Description

本発明は、鉄道等の軌道に沿って形成され、トラフを設置することが可能な補助沈下防止部材を有するトラフ支持部材、トラフ支持部材の敷設方法およびこれらを用いたトラフ橋に関するものである。 The present invention relates to a trough support member having an auxiliary subsidence prevention member formed along a track such as a railway and capable of installing a trough, a method for laying a trough support member, and a trough bridge using these.

従来、鉄道等の軌道に沿って、内部に電力ケーブルや信号ケーブル等が配置されるトラフが設置される場合がある。例えば、地面にトラフ支持部材を立設し、トラフ支持部材上にトラフ受け具を固定することでトラフ橋を形成し、このトラフ橋にトラフを設置することができる。   Conventionally, a trough in which a power cable, a signal cable, and the like are arranged may be installed along a track such as a railway. For example, a trough support member can be erected on the ground, and a trough bridge can be formed by fixing a trough support on the trough support member, and the trough can be installed on the trough bridge.

図１８は、従来のトラフ橋１１０の一例を示す図である。トラフ橋１１０は、主に、トラフ支持部材１００と、トラフ受け具１０１と、トラフ１０３等から構成される。また、トラフ支持部材１００は、支柱１０７、根枷１０９、トラフ受け台１０２等から構成される。   FIG. 18 is a diagram illustrating an example of a conventional trough bridge 110. The trough bridge 110 mainly includes a trough support member 100, a trough support 101, a trough 103, and the like. The trough support member 100 includes a support column 107, a root rod 109, a trough pedestal 102, and the like.

地面１０５には、支柱１０７が打ちこまれる。支柱１０７の地面１０５に埋設される部位には、支柱１０７の長手方向に略垂直に根枷１０９が接合される。根枷１０９は、板状の部材である。支柱１０７の上端は地面１０５より突出する。支柱１０７の上部には、トラフ受け台１０２が固定される。トラフ支持部材１００は、鉄道等の軌道に沿って、所定の間隔で配置される。   A strut 107 is driven into the ground 105. A root rod 109 is joined to a portion of the column 107 embedded in the ground 105 substantially perpendicularly to the longitudinal direction of the column 107. The root rod 109 is a plate-shaped member. The upper end of the column 107 protrudes from the ground 105. A trough cradle 102 is fixed to the upper part of the support column 107. The trough support members 100 are arranged at predetermined intervals along a track such as a railway.

トラフ受け具１０１上には、所定の間隔で配置されたトラフ支持部材１００にまたがるように、トラフ受け具１０１が配置される。トラフ受け具１０１は、例えばレール上の部材であり、上部にトラフ１０３が設置される。   On the trough support 101, the trough support 101 is arrange | positioned so that the trough support member 100 arrange | positioned at predetermined intervals may be straddled. The trough support 101 is a member on a rail, for example, and the trough 103 is installed in the upper part.

従来のトラフ橋１１０は、例えば以下のようにして施工される。まず、トラフ支持部材１００を設置する部位の地面１０５を掘削する。この際、少なくとも、根枷１０９が設置される深さであって、根枷１０９を設置可能な範囲の地面１０５を掘削する。   The conventional trough bridge 110 is constructed as follows, for example. First, the ground 105 at the site where the trough support member 100 is installed is excavated. At this time, the ground 105 is excavated at least at a depth at which the root anchor 109 is installed and in which the root anchor 109 can be installed.

次に、根枷１０９を設置し、支柱１０７を所定の深さまで打ちこむ。その後、根枷１０９上を埋戻し、土を突き固める。支柱１０７の上部にトラフ受け台１０２を固定することで、トラフ支持部材１００の設置が終了する。以上の工程を、鉄道等の軌道に沿って、所定の間隔で行い、トラフ支持部材１００を所定間隔で設置する。   Next, the root rod 109 is installed, and the support column 107 is driven to a predetermined depth. After that, the top of the root rod 109 is backfilled and the soil is solidified. Fixing the trough cradle 102 to the upper part of the support column 107 completes the installation of the trough support member 100. The above steps are performed at predetermined intervals along a track such as a railway, and the trough support members 100 are installed at predetermined intervals.

その後、トラフ受け具１０１を設置し、全長にわたって長手方向にトラフ受け具１０１同士を連結する。トラフ受け具１０１上には、トラフ１０３を配置し、必要に応じて、トラフ受け具１０１の所定の部位に、トラフ固定金具を設置してトラフ１０３を固定する。以上により、トラフ橋１１０の施工が完了する。   Thereafter, the trough receivers 101 are installed, and the trough receivers 101 are connected in the longitudinal direction over the entire length. A trough 103 is arranged on the trough support 101, and a trough fixing bracket is installed at a predetermined part of the trough support 101 as necessary to fix the trough 103. Thus, the construction of the trough bridge 110 is completed.

このような方法では、支柱１０７の沈下防止や倒れ防止のため、根枷１０９が用いられる。このため、根枷１０９を設置するための地盤の掘削作業に工数を要する。また、支柱１０７を打ちこんだ後に、掘削部を埋戻し、突き固める作業工数を要する。   In such a method, the root rod 109 is used to prevent the support column 107 from sinking or falling. For this reason, a man-hour is required for the excavation work of the ground for installing the root anchor 109. In addition, it requires man-hours for backfilling and tamping the excavated portion after the strut 107 is driven.

これに対し、根枷を設置するための掘削を必要としないケーブルトラフ橋の施工方法等が提案されている（例えば特許文献１）。   On the other hand, the construction method of the cable trough bridge etc. which do not require excavation for installing a root anchor are proposed (for example, patent document 1).

特許文献１の方法では、一対の支持杭を用い、支持杭間の間隔を定めてトラフ橋の施工箇所に打ち込むものである。この方法では、両端に一対のリング状嵌め込み輪を有する保持杆が、打ち込んだ支持杭の上端側から、支持杭間に取り付けられる。また、保持杆上にケーブルトラフ橋の幅方向に伸縮調整可能とされたケーブルトラフ固定具を取り付け、取り付けられたケーブルトラフ固定具間にケーブルトラフが敷設される。   In the method of Patent Document 1, a pair of support piles is used, and an interval between the support piles is determined and driven into a construction site of a trough bridge. In this method, a holding rod having a pair of ring-shaped fitting rings at both ends is attached between the support piles from the upper end side of the driven support pile. In addition, a cable trough fixture that can be extended and contracted in the width direction of the cable trough bridge is attached on the holding trough, and the cable trough is laid between the attached cable trough fixtures.

一対の支持杭を打ち込む際には、間隔調整支持具が用いられる。間隔調整支持具の両側の支持杭嵌め込み輪に支持杭を挿通してそれぞれの支持杭を打ちこむことで、支持杭同士の所定の間隔で打ちこむことができる。   When driving a pair of support piles, an interval adjustment support tool is used. By inserting the support piles into the support pile fitting wheels on both sides of the spacing adjustment support tool and driving each support pile, the support piles can be driven at a predetermined interval.

特許文献１の方法によれば、根枷を用いないため、作業が容易である。また、掘削した残土の処理に困ることがない。さらに、部材の重量がきわめて軽量であり、ケーブルトラフの敷設コストがきわめて安価になしうる。   According to the method of Patent Document 1, since the root anchor is not used, the operation is easy. Moreover, there is no problem with the disposal of excavated residual soil. Furthermore, the weight of the member is extremely light, and the cost for laying the cable trough can be extremely low.

特開２０１５−１４２３８７号公報JP2015-142387A

しかし、特許文献１は、管状の支柱を使用するために、硬い地面の場合には摩擦力により打ちこみにくい。また、管状の支柱を２本別々に打ち込んで２本の支柱間距離を調整するため、間隔調整用の支持具を使用する必要がある。このため、間隔調整支持具の着脱作業を必要とするため、作業性が悪い。   However, since Patent Document 1 uses a tubular support, it is difficult to strike due to frictional force in the case of hard ground. Further, in order to adjust the distance between the two struts by separately driving two tubular struts, it is necessary to use a support for adjusting the distance. For this reason, since work for attaching and detaching the interval adjustment supporter is required, workability is poor.

また、２本の杭を打ち込んだ後に、支持杭嵌め込み輪を支持杭に挿通させて、保持杆を支持杭間に取り付け、さらにトラフ橋の幅方向に伸縮調整可能とされたケーブルトラフ固定具を取り付ける等作業が複雑である。また、トラフ支持部材上にトラフを設置し、トラフにケーブルを収容した時に、トラフ支持部材が沈下するおそれがある。   In addition, after driving the two piles, insert the support pile insertion ring into the support pile, attach the holding rod between the support piles, and further fix the cable trough fixture that can be expanded and contracted in the width direction of the trough bridge Work such as installation is complicated. Moreover, when a trough is installed on a trough support member and a cable is accommodated in the trough, the trough support member may sink.

本発明はこのような問題に鑑みてなされたもので、作業が容易であり、トラフ支持部材の沈下や転倒を防止することが可能な補助沈下防止部材を有するトラフ支持部材、トラフ支持部材の敷設方法およびこれらを用いたトラフ橋を提供することを目的とする。 The present invention has been made in view of such problems, and is a trough support member having an auxiliary subsidence prevention member that is easy to work and can prevent the trough support member from sinking or falling, and laying the trough support member The object is to provide methods and trough bridges using them.

前述した目的を達成するために第１の発明は、所定長さの少なくとも２本の支柱が略平行に所定間隔をあけて、前記支柱の頭部近傍で固定部材にて固定されており、前記固定部材は、上部に設けられるトラフ受け具設置部材と、下部に設けられる沈下防止部材と、を具備し、前記固定部材の上面がトラフ受け具設置面であり、前記固定部材の下面が沈下防止面で、さらに前記固定部材の下方に、補助沈下防止部材が着脱可能に設けられていることを特徴とするトラフ支持部材である。 First invention to achieve the above object is opened at least two predetermined distance substantially parallel struts having a predetermined length, is fixed at fixing member in the head near the post, the The fixing member includes a trough receiver installation member provided in an upper part and a settlement preventing member provided in a lower part, and the upper surface of the fixing member is a trough receiver installation surface, and the lower surface of the fixing member is prevented from sinking. The trough support member is characterized in that an auxiliary subsidence prevention member is detachably provided on the surface below the fixing member .

前記補助沈下防止部材の少なくとも一方の端部が、一方の前記支柱に設けられた孔にボルト固定されてもよい。また、前記補助沈下防止部材の他方の端部には、爪部が形成され、前記爪部が前記支柱に引っかかることにより、前記補助沈下防止部材が前記支柱に固定されてもよい。 At least one end of the auxiliary settlement prevention member may be bolted to a hole provided in one of the columns. Further, a claw portion may be formed at the other end of the auxiliary settlement preventing member, and the auxiliary settlement prevention member may be fixed to the column by hooking the claw portion onto the column.

前記補助沈下防止部材の他方の端部には孔が形成され、前記補助沈下防止部材の両方の端部が、それぞれの前記支柱に設けられた孔にボルト固定されてもよい。 A hole may be formed in the other end of the auxiliary settlement prevention member, and both ends of the auxiliary settlement prevention member may be bolted to holes provided in the respective support columns.

前記補助沈下防止部材の両側の固定部にそれぞれ形成された孔は、長穴または併設して形成された複数の孔であり、前記補助沈下防止部材は、前記支柱に設けられた孔と前記長穴または併設して形成された複数の孔とを用いて、前記支柱の孔にボルト固定されることにより、前記固定部材に対して平行あるいは斜めに取り付け可能であってもよい。 The holes formed in the fixing portions on both sides of the auxiliary settlement prevention member are elongated holes or a plurality of holes formed side by side, and the subsidiary settlement prevention member includes the hole provided in the support column and the long hole. It may be possible to attach to the fixing member in parallel or obliquely by being bolted to the hole of the column using a hole or a plurality of holes formed side by side.

前記支柱の所定位置に水抜き孔が形成されてもよい。   A drain hole may be formed at a predetermined position of the support column.

前記支柱の下端部が鋭角に形成されていることが望ましい。   It is desirable that the lower end of the column is formed at an acute angle.

前記固定部材は、上部に設けられるトラフ受け具設置部材と、下部に設けられる沈下防止部材と、を具備し、前記トラフ受け具設置部材と、前記沈下防止部材とが隙間をあけて配置され、前記トラフ受け具設置部材の上面の前記トラフ受け具の設置面と、前記沈下防止部材の下面の前記沈下防止面は、それぞれ平坦に略平行に形成されていて、前記沈下防止部材の下方に、前記補助沈下防止部材が着脱可能に設けられていてもよい。 The fixing member includes a trough receiver installation member provided in an upper part and a settlement prevention member provided in a lower part, and the trough receiver installation member and the settlement prevention member are arranged with a gap therebetween, The installation surface of the trough receiver on the upper surface of the trough receiver installation member and the settlement prevention surface of the lower surface of the settlement prevention member are formed flat and substantially parallel to each other, below the settlement prevention member, The auxiliary subsidence prevention member may be detachably provided .

前記固定部材は、前記支柱の上端から所定距離下方に設けられ、前記固定部材の上方に、前記支柱の上端が突出してもよい。   The fixing member may be provided below the upper end of the support column by a predetermined distance, and the upper end of the support column may protrude above the fixing member.

第１の発明によれば、２本の支柱が固定部材で固定されているため、支柱を個別に打ち込む必要がない。また、支柱を打ちこむ際に、別途間隔調整治具などが不要である。また、２本の支柱を用いるため、根枷がなくても転倒などを防止することができる。このため、根枷を設置するための地盤の掘削が不要となり、埋め戻し作業および突き固め作業も不要となる。このため、支柱の設置が容易である。   According to the first invention, since the two columns are fixed by the fixing member, it is not necessary to drive the columns individually. In addition, a separate spacing adjustment jig or the like is not necessary when driving the struts. In addition, since two struts are used, it is possible to prevent a fall or the like even without a root. For this reason, excavation of the ground for installing the root anchor is unnecessary, and backfilling work and tamping work are also unnecessary. For this reason, installation of a support | pillar is easy.

また、固定部材の下面が地面と接触して、沈下防止面として機能する。このため、支柱が所定以上深くに沈下することを防止することができる。   Further, the lower surface of the fixing member comes into contact with the ground and functions as a sinking prevention surface. For this reason, it can prevent that a support | pillar sinks deeply more than predetermined.

また、固定部材が支柱と溶接で固定されれば、組立作業が不要である。また、また、固定部材が支柱とボルトで固定されれば、ばらして運搬などができるため、保管、運搬が容易である。   Further, if the fixing member is fixed to the support column by welding, assembly work is not necessary. Further, if the fixing member is fixed with the support column and the bolt, it can be separated and transported, so that storage and transport are easy.

また、固定部材の下方に補助沈下防止部材を着脱可能とすることで、より確実に、支柱が所定以上深くに沈下することを防止することができる。例えば、地面の不陸によって、固定部材の下面を地面に接触させることが困難な場合でも、補助沈下防止部材を用いることで、支柱の沈下を防止することができる。   Moreover, by making the auxiliary subsidence prevention member detachable below the fixing member, it is possible to more reliably prevent the support column from sinking deeper than a predetermined depth. For example, even when it is difficult to bring the lower surface of the fixing member into contact with the ground due to unevenness of the ground, the use of the auxiliary settlement prevention member can prevent the support from sinking.

また、補助沈下防止部材が、固定部材に対して斜めに取り付け可能であれば、地面が水平ではない場合にも、補助沈下防止部材を確実に地面に面接触させることができる。このため、設置場所が斜面である場合においても、支柱の沈下を防止することができる。   Further, if the auxiliary subsidence prevention member can be attached obliquely to the fixing member, the auxiliary subsidence prevention member can be brought into surface contact with the ground without fail even when the ground is not horizontal. For this reason, even when the installation location is a slope, it is possible to prevent the column from sinking.

また、補助沈下防止部材は、一方の端部が、一方の支柱に設けられた孔にボルト固定されるようにすれば、補助沈下防止部材を支柱に取り付ける作業が容易である。   Further, if one end of the auxiliary settlement preventing member is bolted to a hole provided in one support column, the work of attaching the auxiliary settlement prevention member to the support column is easy.

また、補助沈下防止部材の両方の端部を、それぞれの支柱に設けられた孔にボルトで固定することで、確実に、補助沈下防止部材を支柱に固定することができる。   Further, by fixing both ends of the auxiliary settlement prevention member to the holes provided in the respective columns with bolts, the auxiliary settlement prevention member can be reliably fixed to the column.

支柱の所定位置に水抜き孔を形成することで、支柱の設置部において地面を流れる水が堰き止められることがない。このため、トラフ橋に沿って、水たまりが形成されることを抑制することができる。   By forming a drain hole at a predetermined position of the support column, the water flowing on the ground is not blocked by the support column installation part. For this reason, it can suppress that a puddle is formed along a trough bridge.

また、支柱の下端部を鋭角に形成することで、支柱を地面に打ち込む作業が容易となる。   Moreover, the operation | work which drives a support | pillar into the ground becomes easy by forming the lower end part of a support | pillar at an acute angle.

また、固定部材が、上部に設けられるトラフ受け具設置部材と、下部に設けられる沈下防止部材とによって構成されることで、トラフ受け具の設置面と、沈下防止面との隙間を大きくとることができる。このため、トラフを設置した際に、地面とトラフ下面との間に隙間を形成することができる。この結果、トラフによって、水が堰き止められることを防止することができる。   In addition, since the fixing member is configured by the trough receiver installation member provided in the upper part and the settlement preventing member provided in the lower part, the clearance between the installation surface of the trough receiver and the settlement prevention surface is increased. Can do. For this reason, when the trough is installed, a gap can be formed between the ground and the lower surface of the trough. As a result, water can be prevented from being blocked by the trough.

この際、トラフ受け具設置部材の上面のトラフ受け具の設置面と、沈下防止部材の下面の沈下防止面が、それぞれ平坦に略平行に形成されるため、トラフ受け具の設置が容易であるとともに、沈下防止面を地面に確実に面接触させることができる。   At this time, the trough receiver installation surface on the upper surface of the trough receiver installation member and the subsidence prevention surface on the lower surface of the subsidence prevention member are formed flat and substantially parallel to each other, so that the trough receiver can be easily installed. At the same time, the settlement-preventing surface can be reliably brought into surface contact with the ground.

また、固定部材が、支柱の上端から所定距離下方に設けられ、固定部材の上方に、支柱の上端が突出するようにすることで、支柱の上部を、トラフ受け具のガイドとして利用することができる。   In addition, the fixing member is provided at a predetermined distance below the upper end of the column, and the upper end of the column protrudes above the fixing member, so that the upper part of the column can be used as a guide for the trough receiver. it can.

第２の発明は、第１の発明にかかるトラフ支持部材を地面に打ち込んだ後で、少なくとも一方の前記支柱に設けられたボルト孔に、前記補助沈下防止部材の一方の端部を固定することを特徴とするトラフ支持部材の敷設方法である。   In the second invention, after the trough support member according to the first invention is driven into the ground, one end of the auxiliary subsidence prevention member is fixed to a bolt hole provided in at least one of the columns. This is a method for laying a trough support member.

補助沈下防止部材を固定した後、前記固定部材の上面にトラフ受け具を固定してもよい。   After fixing the auxiliary subsidence prevention member, a trough receiver may be fixed to the upper surface of the fixing member.

第２の発明によれば、地面の不陸によって、固定部材の下面を地面に接触させることが困難な場合でも、補助沈下防止部材を用いることで、支柱の沈下を防止することができる。   According to the second invention, even when it is difficult to bring the lower surface of the fixing member into contact with the ground due to the unevenness of the ground, the support can be prevented from sinking by using the auxiliary settlement-preventing member.

また、トラフ受け具を固定することで、上部にトラフを設置することが可能なトラフ橋を施工することができる。   Moreover, the trough bridge which can install a trough in the upper part can be constructed by fixing a trough receptacle.

第３の発明は、トラフ支持部材と、前記トラフ支持部材上に設けられるトラフ受け具と、前記トラフ受け具を連結する連結部材と、を具備し、前記トラフ支持部材は、所定長さの少なくとも２本の支柱が略平行に所定間隔をあけて、前記支柱の頭部近傍で固定部材にて固定されており、前記固定部材は、上部に設けられるトラフ受け具設置部材と、下部に設けられる沈下防止部材とから形成され、複数の前記トラフ支持部材が所定の間隔をあけて配置され、複数の前記トラフ支持部材にまたがるように、前記固定部材のトラフ受け具設置部材の上面に前記トラフ受け具が配置され、少なくとも一部の前記沈下防止部材の下方に、補助沈下防止部材が着脱可能に設けられ、前記補助沈下防止部材の沈下防止面が、地面に接触し、前記連結部材は、前記トラフ受け具の端部を挿入可能な空間と、前記空間に突出する係止爪と、を具備し、前記連結部材の両端から、前記トラフ受け具の端部が挿入されて、長手方向に前記トラフ受け具が連結され、前記係止爪が、少なくとも一方の前記トラフ受け具に設けられた係止部に係止されることを特徴とするトラフ橋である。 A third invention includes a trough support member, a trough receiver provided on the trough support member, and a connecting member that connects the trough receiver, and the trough support member has at least a predetermined length. Two struts are fixed by a fixing member in the vicinity of the head of the support column at a predetermined interval substantially in parallel, and the fixing member is provided at a trough support installation member provided at an upper portion and a lower portion. The trough support is formed on the upper surface of the trough support installation member of the fixed member so that the trough support members are arranged at predetermined intervals, and are arranged at predetermined intervals. ingredients is disposed beneath at least a portion of the sinking prevention member, the auxiliary subsidence prevention member is removably provided, the sinking prevention surface of the auxiliary subsidence prevention member is in contact with the ground, the coupling member A space into which the end of the trough receiver can be inserted; and a locking claw protruding into the space.

支柱３は、例えばＬ字状の断面形状の部材である。なお、支柱３の断面形状はL字状に限られず、例えばＵ字状など、任意の形状でよいが、筒状の閉断面形状ではないことが望ましい。支柱３が筒形状であると、支柱３を地面に打ち込む際に、支柱３の内部に石や土が詰まり、抵抗が大きくなるため、打ちこむことが困難になるためである。   The support | pillar 3 is a member of L-shaped cross-sectional shape, for example. In addition, the cross-sectional shape of the support | pillar 3 is not restricted to L shape, For example, although arbitrary shapes, such as U shape, may be sufficient, it is desirable that it is not a cylindrical closed cross-sectional shape. This is because, when the support column 3 has a cylindrical shape, when the support column 3 is driven into the ground, the inside of the support column 3 is clogged with stones and earth, and resistance increases, so that it is difficult to drive in.

なお、支柱３をより打ちこみやすくするため、支柱３の下端部は、鋭角に形成されている。また、所定長さの少なくとも２本の支柱３は、略平行に所定間隔をあけて、支柱３の頭部１３近傍で固定部材５にて固定されて連結される。   In addition, in order to make it easier to strike the support column 3, the lower end portion of the support column 3 is formed at an acute angle. Further, at least two struts 3 having a predetermined length are fixedly connected by a fixing member 5 in the vicinity of the head 13 of the strut 3 at a predetermined interval in parallel.

固定部材５は、上部に設けられるトラフ受け具設置部材７と、下部に設けられる沈下防止部材９からなる。トラフ受け具設置部材７と、沈下防止部材９は、隙間をあけて配置される。トラフ受け具設置部材７の上面は、トラフ受け具設置面１５となる。また、沈下防止部材９の下面は、沈下防止面１７となる。   The fixing member 5 includes a trough support installation member 7 provided in the upper part and a settlement preventing member 9 provided in the lower part. The trough support installation member 7 and the settlement prevention member 9 are arranged with a gap therebetween. The upper surface of the trough receiver installation member 7 is a trough receiver installation surface 15. The lower surface of the settlement preventing member 9 is a settlement preventing surface 17.

トラフ受け具設置面１５は、後述するトラフ受け具が設置される部位である。また、沈下防止面１７は、トラフ支持部材１を地面に打ち込んだ際に、地面と接触し、それ以上支柱３が深くに沈下されることを防止する部位である。トラフ受け具設置面１５と沈下防止面１７とは、それぞれ平坦に略平行に形成される。   The trough support installation surface 15 is a part where a trough support described later is installed. The sinking prevention surface 17 is a part that contacts the ground when the trough support member 1 is driven into the ground, and prevents the column 3 from sinking further deeply. The trough support installation surface 15 and the settlement prevention surface 17 are each formed flat and substantially parallel.

なお、固定部材５は、トラフ受け具設置部材７と沈下防止部材９とが一体で構成されてもよい。この場合でも、固定部材５の上面がトラフ受け具設置面１５であり、固定部材５の下面が沈下防止面１７となり、トラフ受け具設置面１５と沈下防止面１７とは、それぞれ平坦に略平行に形成される。   The fixing member 5 may be configured such that the trough receiver installation member 7 and the settlement preventing member 9 are integrated. Even in this case, the upper surface of the fixing member 5 is the trough receiver installation surface 15, the lower surface of the fixing member 5 is the settlement prevention surface 17, and the trough receiver installation surface 15 and the settlement prevention surface 17 are flat and substantially parallel to each other. Formed.

固定部材５は、支柱３の上端（頭部１３）から所定距離下方に設けられる。このため、固定部材５の上方に、支柱３の上端が突出する。固定部材５は、支柱３と溶接部１９により固定されている。すなわち、トラフ受け具設置部材７と沈下防止部材９は、それぞれ、両端部が支柱３に溶接によって固定される。   The fixing member 5 is provided below the upper end (head 13) of the column 3 by a predetermined distance. For this reason, the upper end of the column 3 protrudes above the fixing member 5. The fixing member 5 is fixed by the support column 3 and the welded portion 19. That is, both ends of the trough receiver installation member 7 and the settlement preventing member 9 are fixed to the support column 3 by welding.

なお、図３に示すように、固定部材５が、支柱３とボルト２３で固定されてもよい。この場合には、トラフ受け具設置部材７と沈下防止部材９は、それぞれ、両端部が折曲げられて、折曲げ部には図示を省略した孔が形成される。また、折曲げ部が当接する支柱３にも同様に孔が設けられ、折曲げ部と支柱３とを貫通するボルト２３によって、両者が固定される。なお、以下の図においては、溶接部１９およびボルト２３の図示を省略する。   As shown in FIG. 3, the fixing member 5 may be fixed by the support column 3 and the bolt 23. In this case, both ends of the trough receiver installation member 7 and the settlement prevention member 9 are bent, and a hole (not shown) is formed in the bent portion. Similarly, a hole is provided in the support column 3 with which the bent portion abuts, and both are fixed by a bolt 23 penetrating the bent portion and the support column 3. In addition, in the following figures, illustration of the welding part 19 and the volt | bolt 23 is abbreviate | omitted.

トラフ受け具設置部材（トラフ受け具設置面１５）には、孔１６が設けられる。孔１６は、後述するトラフ受け具を設置する際に用いられる。また、それぞれの支柱３には、同一方向に向けて孔１１が設けられる。孔１１は、沈下防止部材９の下部に設けられる。孔１１は、後述する補助沈下防止部材を固定する部位である。   A hole 16 is provided in the trough receiver installation member (trough receiver installation surface 15). The hole 16 is used when installing a trough receiver described later. Further, each column 3 is provided with holes 11 in the same direction. The hole 11 is provided in the lower part of the settlement preventing member 9. The hole 11 is a part for fixing an auxiliary settlement prevention member described later.

また、図２に示すように、支柱３の所定位置には、水抜き孔２１が形成される。水抜き孔２１は、沈下防止部材９のわずかに上方に設けられる。例えば、水抜き孔２１は、トラフ受け具設置部材７と沈下防止部材９との間に設けられる。なお、水抜き孔２１は、トラフ受け具設置部材７と沈下防止部材９の間だけでなく、沈下防止部材９の下部にも所定間隔で複数個、両方の支柱３の対応する同一の位置にそれぞれ設けてもよい。このように、支柱３の下端部方向に水抜き孔２１を多く設けることにより、地表面近傍の支柱３の地中埋設部に水が溜ることで地盤が緩むことを防止することができる。   Further, as shown in FIG. 2, a drain hole 21 is formed at a predetermined position of the column 3. The drain hole 21 is provided slightly above the settlement preventing member 9. For example, the drain hole 21 is provided between the trough receiver installation member 7 and the settlement prevention member 9. It should be noted that a plurality of drain holes 21 are provided not only between the trough receiver installation member 7 and the sinking prevention member 9 but also at a lower portion of the sinking prevention member 9 at a predetermined interval at the same corresponding positions of both struts 3. Each may be provided. Thus, by providing many drain holes 21 in the direction of the lower end portion of the support column 3, it is possible to prevent the ground from loosening due to the accumulation of water in the underground portion of the support column 3 near the ground surface.

次に、トラフ支持部材の敷設方法について説明する。まず、図４に示すように、トラフ支持部材１を地面２５に打ち込む（図中矢印Ｂ）。この際、必要に応じて、支柱３の頭部１３に当て治具などを装着して、当て治具の上方からハンマーなどで両方の支柱３を交互に叩くことで、トラフ支持部材１を地面に打ち込むことができる。   Next, a method for laying the trough support member will be described. First, as shown in FIG. 4, the trough support member 1 is driven into the ground 25 (arrow B in the figure). At this time, if necessary, a trough support member 1 is grounded by attaching a striking jig or the like to the head 13 of the strut 3 and alternately striking both struts 3 with a hammer or the like from above the striking jig. Can be driven into.

ここで、トラフ支持部材１の打ち込み深さは、例えば、トラフ受け具２７上に配置固定される図示しないトラフを含めたトラフ支持部材１の全長の７５％に設定することができる。尚、この打ち込み深さは、トラフ支持部材１を打ち込む斜面の傾斜角度、土質、打ち込み時の荷重などを考慮して適宜設定を変更することができる。   Here, the driving depth of the trough support member 1 can be set to, for example, 75% of the total length of the trough support member 1 including the trough (not shown) arranged and fixed on the trough support 27. The driving depth can be appropriately changed in consideration of the inclination angle of the slope into which the trough support member 1 is driven, the soil quality, the load at the time of driving, and the like.

図５は、図４のＡ−Ａ線断面図であり、固定部材５近傍の断面図である。トラフ支持部材１は、固定部材５の下面が地面２５に接触する深さまで、地面２５に打ち込まれる。すなわち、トラフ支持部材１は、沈下防止部材９の下面の沈下防止面１７が地面２５に接するまで打ち込まれる。沈下防止面１７は、平坦であって、支柱３の長手方向に垂直な面であるため、地面２５と面接触する。したがって、支柱３が、地面２５に対して沈下することが抑制される。   FIG. 5 is a cross-sectional view taken along line AA in FIG. 4, and is a cross-sectional view in the vicinity of the fixing member 5. The trough support member 1 is driven into the ground 25 to such a depth that the lower surface of the fixing member 5 comes into contact with the ground 25. That is, the trough support member 1 is driven until the settlement preventing surface 17 on the lower surface of the settlement preventing member 9 contacts the ground surface 25. Since the settlement prevention surface 17 is flat and is a surface perpendicular to the longitudinal direction of the support column 3, it comes into surface contact with the ground surface 25. Therefore, the support column 3 is suppressed from sinking with respect to the ground surface 25.

以上の方法によって、図６に示すように、鉄道等の軌道に沿って、所定の間隔でトラフ支持部材１を配置する。なお、トラフ支持部材１を所定の位置に配置するために、施工治具等を用いてもよい。施工治具を地面に配置し、施工治具に所定の間隔で設けられる位置決め部にトラフ支持部材１を配置して打ち込むことで、トラフ支持部材１を所定の間隔で設置することができる。   By the above method, as shown in FIG. 6, the trough support members 1 are arranged at predetermined intervals along a track such as a railway. In addition, in order to arrange the trough support member 1 in a predetermined position, a construction jig or the like may be used. The trough support member 1 can be installed at a predetermined interval by placing the construction jig on the ground and placing and driving the trough support member 1 into a positioning portion provided at a predetermined interval on the construction jig.

次に、図７に示すように、所定の間隔で配置されたトラフ支持部材１にまたがるように、固定部材５の上面にトラフ受け具２７を配置する。すなわち、トラフ受け具２７は、トラフ受け具設置部材７の上面のトラフ受け具設置面１５上に設置される。   Next, as shown in FIG. 7, the trough support 27 is arranged on the upper surface of the fixing member 5 so as to straddle the trough support members 1 arranged at predetermined intervals. That is, the trough receiver 27 is installed on the trough receiver installation surface 15 on the upper surface of the trough receiver installation member 7.

トラフ受け具２７は、例えば一対のＬ字状の形鋼が所定の間隔でほぼ平行に連結された部材である。すなわち、トラフ受け具２７は、幅方向に互いに対向してＬ字状部材が配置される。   The trough support 27 is a member in which, for example, a pair of L-shaped steel shapes are connected substantially in parallel at a predetermined interval. That is, the trough receiver 27 is arranged with L-shaped members facing each other in the width direction.

なお、トラフ受け具２７の幅は、支柱３同士の間隔よりも狭いため、トラフ受け具２７を固定部材５上に設置した際に、トラフ受け具２７は支柱３の間に設置することができる。また、前述したように、支柱３の上部が固定部材５の上部に突出するため、支柱３の上部をトラフ受け具２７の設置のためのガイド部として利用することができる。   In addition, since the width of the trough receiver 27 is narrower than the space | interval of the support | pillars 3, when the trough receiver 27 is installed on the fixing member 5, the trough receiver 27 can be installed between the support | pillars 3. . Further, as described above, since the upper portion of the support column 3 protrudes from the upper portion of the fixing member 5, the upper portion of the support column 3 can be used as a guide portion for installing the trough receiver 27.

トラフ受け具２７の両端部近傍には、係止部２９が設けられる。係止部２９は、トラフ受け具２７の幅方向に互いに対向して配置されるＬ字状部材の壁部に設けられる。係止部２９は、Ｌ字状部材の壁部の一部が切りかかれた部位となる。係止部２９は、トラフ受け具２７同士を連結する際に使用される部位である。   Locking portions 29 are provided in the vicinity of both ends of the trough support 27. The locking portion 29 is provided on the wall portion of the L-shaped member that is disposed to face each other in the width direction of the trough receiver 27. The locking portion 29 is a portion where a part of the wall portion of the L-shaped member is cut off. The locking part 29 is a part used when connecting the trough receivers 27 to each other.

図８は、トラフ受け具２７同士を連結する際に使用される連結部材３１を示す斜視図である。連結部材３１は、トラフ受け具２７の端部を挿入可能な空間３３と、空間３３に突出する係止爪３５と有する部材である。   FIG. 8 is a perspective view showing a connecting member 31 used when connecting the trough receivers 27 to each other. The connecting member 31 is a member having a space 33 into which an end portion of the trough receiver 27 can be inserted and a locking claw 35 protruding into the space 33.

連結部材３１は、板状の部材が屈曲して構成され、Ｌ字状の一端側が、隙間を開けて内側に折り返されて形成される。すなわち、折り返し部の隙間が、空間３３となる。なお、連結部材３１の空間３３の幅は、トラフ受け具２７の厚みよりも大きく、連結部材３１の空間３３の高さは、トラフ受け具２７のＬ字状部材の高さよりも高い。   The connecting member 31 is formed by bending a plate-like member, and one end side of the L-shape is formed to be folded inward with a gap. That is, the gap between the folded portions becomes the space 33. The width of the space 33 of the connecting member 31 is larger than the thickness of the trough receiver 27, and the height of the space 33 of the connecting member 31 is higher than the height of the L-shaped member of the trough receiver 27.

係止爪３５は、空間３３に対応する部位の一部が切り欠かれて、空間３３側に折り込まれた部位である。なお、係止爪３５は、連結部材３１の一方の端部近傍に形成され、係止爪３５の先端が、逆側の端部側に向けて形成される。   The locking claw 35 is a part that is partly cut away and folded into the space 33 side. The locking claw 35 is formed in the vicinity of one end portion of the connecting member 31, and the tip of the locking claw 35 is formed toward the opposite end portion side.

図９は、トラフ受け具２７がトラフ支持部材１上に固定された状態を示す図である。トラフ受け具２７をトラフ支持部材１の固定部材５上に配置した状態で、固定部材５と対向する部位に固定部材３７を配置し、ボルト３９で固定部材３７が固定される。ボルト３９は、トラフ受け具設置部材７に設けられた孔１６（図１等参照）を貫通して固定される。以上により、トラフ受け具２７は、固定部材５と固定部材３７で挟み込まれて固定される。   FIG. 9 is a view showing a state where the trough support 27 is fixed on the trough support member 1. In a state where the trough support 27 is arranged on the fixing member 5 of the trough support member 1, the fixing member 37 is arranged at a portion facing the fixing member 5, and the fixing member 37 is fixed by the bolt 39. The bolt 39 is fixed through the hole 16 (see FIG. 1 and the like) provided in the trough holder installation member 7. As described above, the trough receiver 27 is sandwiched and fixed between the fixing member 5 and the fixing member 37.

また、長手方向に対向するトラフ受け具２７は、それぞれ連結部材３１の両側から挿入される。連結部材３１は一対使用され、トラフ受け具２７の幅方向のＬ字状部材の端部がそれぞれ挿入される。すなわち、連結部材３１の両端から、トラフ受け具２７の端部が挿入されて、長手方向にトラフ受け具２７が連結される。   Further, the trough receivers 27 facing in the longitudinal direction are respectively inserted from both sides of the connecting member 31. A pair of connecting members 31 are used, and the end portions of the L-shaped members in the width direction of the trough receiver 27 are respectively inserted. That is, the ends of the trough receiver 27 are inserted from both ends of the connecting member 31, and the trough receiver 27 is connected in the longitudinal direction.

図１０は、図９のＣ部近傍の断面図である。前述したように、トラフ受け具２７の先端は、連結部材３１の空間３３にスライド挿入される。この際、トラフ受け具２７を所定の長さ連結部材３１に挿入すると、連結部材３１の係止爪３５がトラフ受け具２７の係止部２９に嵌まり、連結部材３１とトラフ受け具２７が係止される。すなわち、係止爪３５が、連結部材３１の両側から挿入されるトラフ受け具２７の内、少なくとも一方のトラフ受け具２７の係止部２９に係止される。   10 is a cross-sectional view of the vicinity of a portion C in FIG. As described above, the tip of the trough receiver 27 is slid into the space 33 of the connecting member 31. At this time, when the trough receiver 27 is inserted into the connecting member 31 with a predetermined length, the engaging claw 35 of the connecting member 31 is fitted into the engaging portion 29 of the trough receiver 27, and the connecting member 31 and the trough receiver 27 are connected. Locked. That is, the locking claw 35 is locked to the locking portion 29 of at least one of the trough receivers 27 inserted from both sides of the connecting member 31.

以上により、トラフ受け具２７を長手方向に連結する。図１１は、トラフ橋５０を示す図である。図１１に示すように、トラフ受け具２７の上部にトラフ４１を配置する。なお、前述したように、沈下防止面１７が地面２５に接触し、沈下防止面１７とトラフ受け具設置面１５とが、隙間をあけて配置される（図５参照）。このため、トラフ４１を設置した際に、トラフ４１の下部に地面２５との間に隙間４３が形成される。したがって、トラフ４１によって、雨水などが堰き止められることを防止することができる。   Thus, the trough receiver 27 is connected in the longitudinal direction. FIG. 11 is a diagram illustrating the trough bridge 50. As shown in FIG. 11, the trough 41 is disposed on the upper part of the trough receiver 27. As described above, the settlement prevention surface 17 contacts the ground 25, and the settlement prevention surface 17 and the trough receiver installation surface 15 are disposed with a gap (see FIG. 5). For this reason, when the trough 41 is installed, a gap 43 is formed between the lower surface of the trough 41 and the ground 25. Therefore, the trough 41 can prevent rainwater and the like from being blocked.

尚、特に図示しないが、トラフ受け具２７上へのトラフ４１の固定は、トラフ受け具２７にトラフ固定用の固定金具を取り付け、その固定金具により、トラフ４１の底部に形成されるリブを押さえることで固定したり、鉄製の結束バンドで、トラフ４１を直接固定したりすることができる。   Although not particularly shown, the trough 41 is fixed on the trough receiver 27 by attaching a fixing bracket for fixing the trough to the trough receiver 27 and pressing the rib formed on the bottom of the trough 41 with the fixing bracket. The trough 41 can be directly fixed with an iron binding band.

以上、本実施の形態によれば、一対の支柱３が固定部材５で固定されており、トラフ支持部材１の倒れを防止することができる。また、間隔調整治具などが不要であり、先端が鋭角に形成されているため、打ち込み作業が良好である。また、支柱３として管状でなくＬ字状やＵ字状などの形鋼を使用しているため、硬い岩や石が管の内部に詰まることがなく、打ち込みが容易である。   As mentioned above, according to this Embodiment, a pair of support | pillar 3 is being fixed by the fixing member 5, and the fall of the trough support member 1 can be prevented. In addition, since an interval adjusting jig or the like is unnecessary and the tip is formed at an acute angle, the driving operation is good. In addition, since the column 3 is made of a steel shape such as an L shape or a U shape instead of a tubular shape, hard rocks and stones are not clogged inside the tube and can be driven easily.

また、沈下防止部材９によって、支柱３がそれ以上地中に沈下することが防止される。このため、根枷などの部材を用いることなく、支柱の沈下を防止することができる。また、地震などにより、地中に埋設された支柱３に応力がかかった場合でも、地面２５に接触する支柱３の沈下防止部材９により支持されているので変形することを抑制することができる。   Further, the settlement prevention member 9 prevents the support column 3 from sinking further into the ground. For this reason, it is possible to prevent the column from sinking without using a member such as a root anchor. Further, even when stress is applied to the pillar 3 embedded in the ground due to an earthquake or the like, deformation can be suppressed because it is supported by the settlement preventing member 9 of the pillar 3 in contact with the ground 25.

また、沈下防止部材９とトラフ受け具設置部材７を別に設けて、間に隙間をあけることで、トラフ４１を設置した際に、トラフ４１と地面２５との間に隙間４３を形成することができる。このため、トラフ４１によって、水等が堰き止められることを防止することができる。なお、トラフ支持部材１においては、水抜き孔２１によって水が流れるため、水の流れを堰き止めることがない。   Moreover, when the trough 41 is installed, the clearance 43 can be formed between the trough 41 and the ground 25 by providing the sinking prevention member 9 and the trough holder installation member 7 separately and providing a gap therebetween. it can. For this reason, it is possible to prevent water or the like from being blocked by the trough 41. In addition, in the trough support member 1, since water flows through the drain hole 21, the water flow is not blocked.

また、沈下防止部材９とトラフ受け具設置部材７を、一対の支柱３の固定部材５として利用するため、支柱３を確実に連結して固定し、補強することができる。   In addition, since the settlement preventing member 9 and the trough support installation member 7 are used as the fixing members 5 of the pair of support columns 3, the support columns 3 can be reliably connected, fixed, and reinforced.

また、固定部材５が、支柱３の頭部１３から所定距離低い位置に設けられるため、支柱３の上部を、トラフ受け具設置面１５から上方に突出させることができる。このため、支柱３の上部を、トラフ受け具２７の設置のためのガイドとして使用することができる。   Further, since the fixing member 5 is provided at a position lower by a predetermined distance from the head 13 of the column 3, the upper portion of the column 3 can be protruded upward from the trough holder installation surface 15. For this reason, the upper part of the support | pillar 3 can be used as a guide for installation of the trough receptacle 27. FIG.

また、トラフ受け具２７同士を連結する連結部材３１を用いることで、トラフ受け具２７の設置および連結が容易である。この際、トラフ受け具２７の係止部２９が、連結部材３１に係止爪３５によって係止されるため、トラフ受け具２７が連結部材３１から抜けることを防止することができる。   Moreover, installation and connection of the trough receiver 27 are easy by using the connection member 31 which connects the trough receivers 27 to each other. At this time, since the locking portion 29 of the trough receiver 27 is locked to the connecting member 31 by the locking claw 35, it is possible to prevent the trough receiver 27 from coming off the connecting member 31.

なお、係止されていない側のトラフ受け具２７は、連結部材３１に対して移動可能であるが、トラフ支持部材１上に設置されたトラフ受け具２７は、固定部材３７によって軸方向への移動量が規制される。このため、トラフ受け具２７が連結部材３１から抜けることがない。また、連結部材３１によって、トラフ受け具２７に多少のスライド代が設けられるため、トラフ受け具２７の長手方向の位置ずれも吸収可能である。   The trough receiver 27 on the non-locked side is movable with respect to the connecting member 31, but the trough receiver 27 installed on the trough support member 1 is moved in the axial direction by the fixing member 37. The amount of movement is regulated. For this reason, the trough receiver 27 does not come off from the connecting member 31. Further, since the slide member 27 is provided with a slight sliding allowance by the connecting member 31, it is possible to absorb the displacement in the longitudinal direction of the trough receiver 27.

次に、他の実施形態について説明する。図１２は、トラフ支持部材１を所定間隔で設置した状態を示す図である。本実施形態では、地面２５に不陸があり、地面２５の一部が低くなっている。したがって、図の中央のトラフ支持部材１を地面２５に対して、他のトラフ支持部材１と同様に設置してしまうと、当該部位のみ低くなってしまう。この場合に、トラフ４１を水平に配置するためには（図中Ｅ）、対象となるトラフ支持部材１の、当該部位における地面２５からの打ちこみ量を少なくする必要がある。   Next, another embodiment will be described. FIG. 12 is a diagram illustrating a state where the trough support members 1 are installed at predetermined intervals. In the present embodiment, the ground 25 is uneven and a part of the ground 25 is low. Therefore, if the trough support member 1 in the center of the figure is installed with respect to the ground 25 in the same manner as the other trough support members 1, only that portion is lowered. In this case, in order to arrange the trough 41 horizontally (E in the drawing), it is necessary to reduce the amount of the trough support member 1 to be driven from the ground 25 at the site.

この場合には、補助沈下防止部材４５が用いられる。図１３は、補助沈下防止部材４５を示す斜視図である。補助沈下防止部材４５は、正面視において略Ｕ字状であり、側面視において略Ｌ字状の部材である。   In this case, the auxiliary settlement prevention member 45 is used. FIG. 13 is a perspective view showing the auxiliary settlement prevention member 45. The auxiliary settlement prevention member 45 is a substantially U-shaped member in a front view and a substantially L-shaped member in a side view.

補助沈下防止部材４５の下面は平坦な沈下防止面４７となる。補助沈下防止部材４５の幅方向の両側には、沈下防止面４７に対してほぼ垂直に、固定部４８が設けられる。固定部４８には、長穴４９が設けられる。なお、長穴に代えて、複数の孔を併設してもよい。   The lower surface of the auxiliary settlement prevention member 45 is a flat settlement prevention surface 47. Fixing portions 48 are provided on both sides in the width direction of the auxiliary settlement prevention member 45 so as to be substantially perpendicular to the settlement prevention surface 47. The fixing portion 48 is provided with a long hole 49. In place of the long hole, a plurality of holes may be provided.

図１４は、図１２のＤ部におけるトラフ支持部材１の正面図であり、図１５は、図１４のＦ−Ｆ線断面図である。前述したように、地面２５が低いため、トラフ支持部材１の沈下防止部材９は、地面２５とは接触せず、地面２５よりも高い位置に配置される。一方、支柱３には、補助沈下防止部材４５の固定部４８が配置されて、ボルト５１によって固定される。なお、ボルト５１は、固定部４８の長穴４９と、支柱３の孔１１を貫通するように配置される。   14 is a front view of the trough support member 1 in the D part of FIG. 12, and FIG. 15 is a cross-sectional view taken along line FF of FIG. As described above, since the ground 25 is low, the settlement preventing member 9 of the trough support member 1 is not in contact with the ground 25 and is disposed at a position higher than the ground 25. On the other hand, a fixing portion 48 of the auxiliary subsidence prevention member 45 is disposed on the column 3 and is fixed by a bolt 51. The bolt 51 is disposed so as to pass through the long hole 49 of the fixing portion 48 and the hole 11 of the column 3.

このように、補助沈下防止部材４５は、固定部材５の下方に着脱可能であるため、不要な場合には、取り外すことができる。すなわち、沈下防止部材９を地面２５に接触させることができる部位では、補助沈下防止部材４５を装着する必要がない。したがって、所定の間隔で配置された複数のトラフ支持部材１の内、少なくとも一部のトラフ支持部材１については、固定部材５の下面が地面２５に接触する。   Thus, since the auxiliary settlement prevention member 45 is detachable below the fixing member 5, it can be removed when unnecessary. That is, it is not necessary to attach the auxiliary subsidence prevention member 45 at a portion where the subsidence prevention member 9 can be brought into contact with the ground surface 25. Therefore, the lower surface of the fixing member 5 is in contact with the ground 25 for at least some of the trough support members 1 arranged at a predetermined interval.

なお、補助沈下防止部材４５の固定位置は、長穴４９によって調整可能である。すなわち、補助沈下防止部材４５の沈下防止面４７は、トラフ支持部材１の沈下防止面１７よりも低い位置の任意の位置に調整可能である。   The fixing position of the auxiliary settlement prevention member 45 can be adjusted by the long hole 49. That is, the subsidence prevention surface 47 of the auxiliary subsidence prevention member 45 can be adjusted to an arbitrary position lower than the subsidence prevention surface 17 of the trough support member 1.

このようにして、トラフ支持部材１を地面に打ち込んだ後で、支柱３に設けられた孔１１に、補助沈下防止部材４５を固定することで、補助沈下防止部材４５の沈下防止面４７を地面２５に接触させることができる。このため、それ以上、トラフ支持部材１が地面２５に沈下することを防止することができる。   In this way, after the trough support member 1 is driven into the ground, the subsidence prevention surface 47 of the auxiliary subsidence prevention member 45 is fixed to the ground 11 by fixing the auxiliary subsidence prevention member 45 in the hole 11 provided in the column 3. 25 can be contacted. For this reason, it is possible to prevent the trough support member 1 from sinking to the ground 25 any more.

このように、補助沈下防止部材４５を固定した後、トラフ支持部材１の固定部材５の上面（トラフ受け具設置面１５）にトラフ受け具２７を設置して固定することで、トラフ橋を施工することができる。   In this way, after fixing the auxiliary subsidence prevention member 45, the trough bridge 27 is constructed by installing and fixing the trough receiver 27 on the upper surface (trough receiver installation surface 15) of the fixing member 5 of the trough support member 1. can do.

なお、図１４に示す例では、補助沈下防止部材４５の両方の端部（固定部４８）が、それぞれの支柱３に設けられた孔１１にボルト５１で固定される例を示したが、これに限られない。例えば、補助沈下防止部材４５の一方の端部（固定部４８）のみが、それぞれの支柱３に設けられた孔１１にボルト５１で固定されてもよい。   In the example shown in FIG. 14, an example is shown in which both ends (fixed portions 48) of the auxiliary settlement prevention member 45 are fixed to the holes 11 provided in the respective columns 3 with the bolts 51. Not limited to. For example, only one end portion (fixing portion 48) of the auxiliary settlement prevention member 45 may be fixed to the hole 11 provided in each column 3 with the bolt 51.

図１６（ａ）は、補助沈下防止部材４５の他の固定構造を示す正面図、図１６（ｂ）は、図１６（ａ）のＧ−Ｇ線断面図である。本実施形態では、補助沈下防止部材４５には、一方のみに長穴４９が設けられる。補助沈下防止部材の他方の側には、支柱３の端部に引っかかるように爪部５３が設けられる。   FIG. 16A is a front view showing another fixing structure of the auxiliary settlement prevention member 45, and FIG. 16B is a cross-sectional view taken along the line GG of FIG. In the present embodiment, the auxiliary subsidence prevention member 45 is provided with a long hole 49 only on one side. A claw portion 53 is provided on the other side of the auxiliary subsidence prevention member so as to be caught by the end portion of the column 3.

本実施形態では、爪部５３が支柱３に引っかかっているため、支柱３に対して傾きが規制される。したがって、補助沈下防止部材４５は、支柱３に対して、多少の傾斜は許容されたとしても、支柱３に対してほぼ垂直に取り付けることができる。このため、沈下防止面４７を支柱３に対してほぼ垂直に維持することができる。   In this embodiment, since the claw part 53 is caught by the support | pillar 3, inclination with respect to the support | pillar 3 is controlled. Therefore, the auxiliary settlement prevention member 45 can be attached substantially vertically to the support column 3 even if a slight inclination is allowed with respect to the support column 3. For this reason, the settlement prevention surface 47 can be maintained substantially perpendicular to the column 3.

このように、補助沈下防止部材４５は、少なくとも一方の端部を、いずれかの支柱３に固定することで、沈下防止面４７を地面２５に対して面接触させることができ、トラフ支持部材１の沈下を防止することができる。   As described above, the subsidence prevention member 45 can bring the subsidence prevention surface 47 into surface contact with the ground 25 by fixing at least one end to any of the columns 3, and the trough support member 1. Can be prevented from sinking.

また、上述した実施形態では、地面２５がトラフ支持部材１に対してほぼ垂直である場合（すなわち、地面２５が略水平である場合）を示したが、地面２５がトラフ支持部材１の幅方向に傾斜していてもよい。   In the above-described embodiment, the case where the ground 25 is substantially perpendicular to the trough support member 1 (that is, the ground 25 is substantially horizontal) is shown. However, the ground 25 is in the width direction of the trough support member 1. It may be inclined.

図１７は、傾斜した地面２５にトラフ支持部材１を設置した状態を示す図である。この場合でも、トラフ支持部材１は、鉛直方向に設置される。このため、沈下防止面が支柱３に対して垂直に形成されていると、沈下防止面を地面２５に面接触させることができない。   FIG. 17 is a diagram illustrating a state in which the trough support member 1 is installed on the inclined ground surface 25. Even in this case, the trough support member 1 is installed in the vertical direction. For this reason, if the settlement prevention surface is formed perpendicular to the support column 3, the settlement prevention surface cannot be brought into surface contact with the ground surface 25.

例えば、長穴４９の穴幅をボルト径より幅広に形成し、それぞれの支柱３に対して、補助沈下防止部材４５の両方の固定部４８をそれぞれ固定することで、補助沈下防止部材４５を固定部材５に対して平行あるいは斜めに取り付け可能である。For example, the hole width of the long hole 49 is formed wider than the bolt diameter, and both the fixing portions 48 of the auxiliary subsidence prevention member 45 are fixed to the respective columns 3 to fix the auxiliary subsidence prevention member 45. It can be attached to the member 5 in parallel or obliquely.

このように、補助沈下防止部材４５を用いることで、地面２５が低い部位や傾斜面でも、トラフ受け具設置面１５の高さを維持した状態で、トラフ支持部材１の沈下を防止することができる。   In this way, by using the auxiliary settlement prevention member 45, the trough support member 1 can be prevented from sinking while the height of the trough support installation surface 15 is maintained even on a portion where the ground 25 is low or an inclined surface. it can.

また、地震などで、地面２５の地中の土砂の状態が変化しても、補助沈下防止部材４５が支柱に固定されることで、トラフ支持部材１の剛性が向上して、支柱３の間隔がほぼ一定に保たれることから、トラフ支持部材１が傾くことがない。   Further, even when the state of the earth and sand in the ground 25 changes due to an earthquake or the like, the subsidence prevention member 45 is fixed to the column, so that the rigidity of the trough support member 1 is improved and the interval between the columns 3 is increased. Is kept substantially constant, the trough support member 1 does not tilt.

また、補助沈下防止部材４５を用いる場合には、前述した水抜き孔２１は、トラフ受け具設置部材７と沈下防止部材９の間だけでなく、沈下防止部材９の下部にも所定間隔で複数個、両方の支柱３の対応する同一の位置にそれぞれ設けてもよい。このように水抜き孔２１を配置することにより、補助沈下防止部材４５を設けた時に、補助沈下防止部材４５近傍に雨水などがたまることを防止することをできる。   Further, when the auxiliary subsidence prevention member 45 is used, the above-described drain holes 21 are provided not only between the trough receiver installation member 7 and the subsidence prevention member 9 but also at a lower portion of the subsidence prevention member 9 at a predetermined interval. Each may be provided at the same corresponding position on both struts 3. By disposing the drain hole 21 in this way, it is possible to prevent rainwater and the like from accumulating in the vicinity of the auxiliary subsidence prevention member 45 when the auxiliary subsidence prevention member 45 is provided.
