Description

本発明は、圃場近くに設置された用水路などの既設水路の補修装置及びその補修方法に関するものである。 The present invention relates to a repair device for an existing water channel such as an irrigation channel installed near a farm field and a repair method thereof.

（水路の劣化）
農業用水路などの用水路は、セメント、金属製波板（鋼矢板）などによって作られ、田圃と水路とを区画するが、長期間使用されていくと、経年劣化し、セメントにひび割れが入ったり、波板が錆びて所々、穴が開いてしまったりして、望ましくない場所で水が水路から漏れ、田圃に溢れてしまうといった被害が良く起こる。 (Water channel deterioration)
Irrigation canals such as agricultural canals are made of cement, corrugated metal sheets (steel sheet piles), etc., partitioning rice fields and waterways, but with long-term use, they will deteriorate over time, cracking cement, The corrugated sheet rusts and holes are pierced in some places, causing damage such as water leaking from the waterways and overflowing into the rice fields in undesirable places.

（従来の補修方法）
このように経年劣化した既設水路を補修するために、従来は、クレーンなどの重機をトラック等の車両を使って現場へ搬入し、その重機で新品（交換用）の補修板を吊持しながら劣化部分にあてがい、劣化部分を補修することが一般的である。 (Conventional repair method)
In order to repair existing water channels that have deteriorated over time in this way, conventionally, heavy machinery such as cranes are carried into the site using trucks and other vehicles, and new heavy (replacement) repair plates are being held by the heavy machinery. It is common to apply to the deteriorated part and repair the deteriorated part.

（従来の補修方法で必要な重機と作業運搬路を利用することによる問題点）
しかしながら、現場への重機の搬入や移動には、既設水路脇に沿った田圃の一部を埋め立てて作業運搬路を確保する必要があり、作業運搬路用の土地を補修期間（ある程度長い期間）、田圃保有者から、借り上げなくてはならない。水路周辺の田圃や農地を一旦、埋め立てて作業運搬路としての使用が完了した後、元の借りた状態の農地に戻す作業も必要になる。このように、重機を利用した従来の水路補修には直接役立たない借地や作業運搬路施工のための余分なコストが掛かっていた。 (Problems due to the use of heavy machinery and work haulage required by conventional repair methods)
However, it is necessary to reclaim a part of the rice field along the existing waterway to secure a work transportation path for carrying heavy equipment to the site and repairing the land for the work transportation path (a somewhat long period) You have to borrow from the farmer. It is also necessary to return the farmland to the original borrowed farmland after the land and farmland around the waterway have been reclaimed and used as a work transport path. Thus, the conventional water channel repair using heavy machinery has incurred extra costs for construction of leased land and work transportation routes that are not directly useful.

その上、従来方法では、補修完了後、外見上は作業運搬路から農地に戻せたとしても、農地の土壌特性が変化するなど、農地や農作物などへ環境的な影響を与えかねない。 In addition, in the conventional method, even if the work can be returned to the farmland after the repair is completed, the soil characteristics of the farmland may change, which may have an environmental impact on the farmland and crops.

また、重機を利用した従来方法では、稲刈り等の時期に当たると、借上げ交渉は拒否され、作業運搬路の確保が難しくなり、補修計画が立てづらいといった施工計画上の問題も指摘されている。 Also, with conventional methods using heavy machinery, borrowing negotiations are rejected at the time of rice harvesting, making it difficult to secure a work transportation route, and problems in construction planning such that it is difficult to make a repair plan have been pointed out.

ところで、既設水路の補修に関連した先行技術として、例えば、特許文献１が既に開示されている。この特許文献１では、パネル材を保持する保持機構と、パネル材とともに保持機構を垂直及び水平に移動可能な揚重機（垂直移動機構）及び水平移動機構とを備えたパネル取付装置が開示されている。特許文献１に開示のパネル取付装置では、開口部下向きのコの字状を成す支持部の両端部を水路脇の地面深くに埋設することで、パネル取付装置を、水路を跨いだ状態で水路脇に立設・固定させている。 By the way, as a prior art related to repair of an existing water channel, for example, Patent Document 1 has already been disclosed. This Patent Document 1 discloses a panel attachment device that includes a holding mechanism that holds a panel material, a lifting machine (vertical movement mechanism) that can move the holding mechanism vertically and horizontally together with the panel material, and a horizontal movement mechanism. Yes. In the panel mounting apparatus disclosed in Patent Document 1, the panel mounting apparatus is placed in a state in which the panel mounting apparatus straddles the water channel by embedding both ends of the support portion having a U-shape downwardly facing the opening deep in the ground beside the water channel. Stands and fixes to the side.

しかしながら、水路の一箇所での補修が終了し、少し離れた箇所（例えば、水路の流れ方向に沿って離れた箇所）で再度、新品パネルを使った補修作業を行いたい場合、上記のパネル取付装置を重機やトラックなどの車両で移動させて水路脇の所望の位置に再度設置させる必要がある他、新品パネル等を次の補修箇所の水路脇まで移動させる必要がある。 However, if repair at one location of the waterway is completed and you want to perform repair work using a new panel again at a location slightly away (for example, a location away along the flow direction of the waterway), install the panel above. It is necessary to move the apparatus with a vehicle such as a heavy machine or a truck and install it again at a desired position beside the waterway, and it is also necessary to move a new panel or the like to the side of the waterway at the next repair site.

要するに、特許文献１では、水路のある一箇所での効率的なパネル材の移動・施工を行う機構が開示されているが、水路全体（通常はある程度の長い距離を持つ）に対して連続的な補修作業を行う際でも、パネル材の搬入から水路内への移動及び取付けまでの効率的な移動・取付けを容易く行える機構までは開示されていない。また、特許文献１の技術は、その構造やその説明を見る限り、水路脇の作業用運搬路の造設や、水路脇での重機の利用を完全に排除できるとは言い難い。 In short, Patent Document 1 discloses a mechanism for efficiently moving and constructing a panel material at one place where there is a water channel, but it is continuous with respect to the entire water channel (usually having a certain long distance). Even when performing repair work, there is no disclosure of a mechanism that facilitates efficient movement / mounting from the loading of the panel material to the movement and mounting in the water channel. In addition, as far as the structure and description thereof are concerned, it is difficult to say that the technology of Patent Document 1 can completely eliminate the construction of a work transport path beside the water channel and the use of heavy machinery beside the water channel.

本発明によれば、既設水路の補修装置として、市販の重機や車両に比べて簡素かつ軽量な構成の上記クレーン本体と、上記運搬用台車と、を利用・搬入するだけで補修作業を実行できるため、従来の方法で必須であった重機を利用する必要がない。 According to the present invention, as an existing waterway repair device, repair work can be performed simply by using and carrying in the crane main body and the transport carriage having a simpler and lighter configuration than commercially available heavy machinery and vehicles. Therefore, it is not necessary to use heavy machinery that was essential in the conventional method.

そのうえ、本発明では、補修箇所（例えば、パネル材を積んだ車両が停車している田圃脇の道路から離れた田圃の奥まで延びた水路内の補修箇所）までパネル材を運ぶために、運搬用台車の架台にパネル材を積載して該台車を水路側壁に沿って走行させるだけで良いので、水路脇に従来のような重機やパネル材を補修箇所まで運び込んだり、運び出したりするための作業運搬路を造設する必要がないため、これに要するコストや時間を無くすことができる。 Moreover, in the present invention, in order to carry the panel material to a repair location (for example, a repair location in a waterway extending to the back of the rice field far from the road on the side of the rice field where the vehicle loaded with the panel material is stopped) It is only necessary to load the panel material on the carriage base and run the truck along the side wall of the trolley, so it is necessary to carry heavy machinery and panel materials to the repair site alongside the water channel. Since it is not necessary to construct a transportation path, costs and time required for this can be eliminated.

作業運搬路を不要とすることは、地主との借地交渉や水路脇の農地を傷めたりすることが殆どないため、農地の土壌特性の改変や悪化を心配することもない。さらには、水路の補修時期を、水路に近接した農作地の種まき時期や収穫時期から避ける必要もないため、一年中を通して補修を行いやすくなり、補修計画も立てやすくなるといったメリットも享受できるようになる。 Eliminating the work haulway hardly negotiates leases with landowners or damages the farmland beside the waterway, so there is no concern about alteration or deterioration of the soil characteristics of the farmland. Furthermore, since it is not necessary to avoid the repairing time of the waterway from the sowing time and harvesting time of the agricultural land close to the waterway, it will be possible to enjoy the benefits that it will be easier to make repairs throughout the year and to make a repair plan. become.

（補修装置の説明）
図１は、既存水路Ｃに設置した本発明の補修装置１を示した斜視図である。補修装置１は、大きく分類して、クレーン本体２と運搬用台車３とによって構成される。図２（ａ）に、水路側壁Ｗの上面Ｗｔ上に設置したクレーン本体２の正面図を示し、図２（ｂ）に水路側壁Ｗの上面Ｗｔ上に設置した運搬用台車３の正面図を示す。 (Description of repair device)
FIG. 1 is a perspective view showing a repair device 1 of the present invention installed in an existing water channel C. FIG. The repair device 1 is roughly classified into a crane body 2 and a transport carriage 3. 2A shows a front view of the crane body 2 installed on the upper surface Wt of the water channel side wall W, and FIG. 2B shows a front view of the transport carriage 3 installed on the upper surface Wt of the water channel side wall W. Show.

先ず、クレーン本体２の構造について詳しく説明する。クレーン本体２は、一対の支柱部２１，２１と、支柱部２１，２１を水路側壁Ｗ，Ｗの上に立設・固定する一対の基台部２２，２２と、支柱部２１，２１の上部２１ｔ，２１ｔに取り付けられた水平支持部２３と、を有する。それゆえ、クレーン本体２の正面視の輪郭は、下向きコ字状に形成される。なお、支柱部２１には、図１に示すように、支柱部２１や水平支持部２３を安定的に固定するための補強材２１ａ，２１ｂを追加してもよい。 First, the structure of the crane body 2 will be described in detail. The crane body 2 includes a pair of column portions 21 and 21, a pair of base portions 22 and 22 for standing and fixing the column portions 21 and 21 on the channel side walls W and W, and upper portions of the column portions 21 and 21. 21t, and a horizontal support portion 23 attached to the 21t. Therefore, the outline of the crane body 2 as viewed from the front is formed in a downward U-shape. As shown in FIG. 1, reinforcing members 21 a and 21 b for stably fixing the column 21 and the horizontal support 23 may be added to the column 21.

クレーン本体２は、さらに、水平支持部２３によって水平（つまり、水平方向の左右）に移動自在に支持された揚重機２４と、揚重機２４から垂直（つまり、垂直方向の上下）に移動自在に吊り下げられてパネル材Ｐを保持する保持部２５と、揚重機２４の水平移動と保持部２５の垂直移動の操作を行うための操作部２６と、を備える。保持部２５は、例えば、図３（ａ）に示すようにフック２５ａと、チェーン２５ｂ、このフック２５ａに引っ掛けられてパネル材Ｐに接続可能なロープ２５ｃを備えていてもよい。パネル材Ｐの表面Ｐｓ_１には、ロープ２５ｃを着脱自在に係合可能な係合部Ｐａが設けられていてもよい。 The crane body 2 is further supported by a horizontal support 23 so as to be movable horizontally (that is, horizontally in the horizontal direction), and vertically movable from the lift 24 (that is, vertically up and down). A holding unit 25 that is suspended and holds the panel material P, and an operation unit 26 for performing the horizontal movement of the lifting machine 24 and the vertical movement of the holding unit 25 are provided. For example, as shown in FIG. 3A, the holding unit 25 may include a hook 25 a, a chain 25 b, and a rope 25 c that is hooked on the hook 25 a and can be connected to the panel member P. The surface Ps ₁ of the panel material P may be provided with an engaging portion Pa capable of detachably engaging the rope 25c.

本実施例では、支柱部２１、基台部２２、及び水平支持部２３は、Ｈ形鋼で作られており、揚重機２４の上部に設けられた移動ローラー２４ｒが、操作部２６からの指示によって、水平支持部２３のＨ形鋼の両側に突出した板に沿って走行することで揚重機２４の本体が水平に移動可能となる。 In this embodiment, the column part 21, the base part 22, and the horizontal support part 23 are made of H-shaped steel, and the moving roller 24r provided on the upper part of the lifting machine 24 is instructed from the operation part 26. Thus, the main body of the lifting machine 24 can be moved horizontally by traveling along the plates protruding on both sides of the H-shaped steel of the horizontal support portion 23.

クレーン本体２の基台部２２，２２には、水路側壁Ｗ，Ｗの上面Ｗｔ，Ｗｔを走行可能な本体用車輪２７，２７が設けられる。このような構成のクレーン本体２は、例えば、作業者Ｏが支柱部２１，２２を水路Ｃに沿って平行に押していくことで、水路側壁Ｗ，Ｗ上を水路Ｃの長手方向に沿って走行可能となる。 The base parts 22 and 22 of the crane main body 2 are provided with main body wheels 27 and 27 capable of traveling on the upper surfaces Wt and Wt of the water channel side walls W and W. The crane main body 2 having such a configuration travels along the longitudinal direction of the water channel C on the water channel side walls W and W by, for example, the operator O pushing the support columns 21 and 22 in parallel along the water channel C. It becomes possible.

次に、運搬用台車３の構造について詳しく説明する。運搬用台車３は、パネル材Ｐを載置可能な架台３１と、架台３１が水路Ｃを跨ぐように架台３１を保持可能な枠体３２と、水路側壁Ｗ，Ｗの上面Ｗｔ，Ｗｔを走行可能な台車用車輪３３，３３と、を備える。このような構成の運搬用台車３は、パネル材Ｐを積載しながら水路側壁Ｗ，Ｗ上を水路Ｃの長手方向に沿って走行可能となる。また、運搬用台車３に枠体３２の少なくとも一端（図１では矢印の方向における前方端）の隅部から垂直に延びたハンドル部３４，３４が設けられており、これにより、作業者Ｏは自身の体を無理に曲げずに運搬用台車３を水路Ｃに沿って水平移動させられるようになる。なお、クレーン本体２の基台部２２，２２の少なくとも一端にも、上記ハンドル部３４と同様の構造のハンドル部（図示せず）を立設させてもよい。 Next, the structure of the transport carriage 3 will be described in detail. The carriage 3 travels on a gantry 31 on which the panel material P can be placed, a frame 32 that can hold the gantry 31 so that the gantry 31 straddles the water channel C, and upper surfaces Wt and Wt of the water channel side walls W and W. Possible wheels 33 for the carriage. The transport carriage 3 having such a configuration can travel on the water channel side walls W, W along the longitudinal direction of the water channel C while the panel material P is loaded. Further, the carriage 3 is provided with handle portions 34, 34 extending vertically from the corners of at least one end of the frame 32 (the front end in the direction of the arrow in FIG. 1). The carriage 3 can be moved horizontally along the water channel C without forcibly bending its own body. A handle portion (not shown) having the same structure as the handle portion 34 may be erected on at least one end of the base portions 22 and 22 of the crane body 2.

なお、運搬用台車３の水路幅方向の幅３ｗがクレーン本体２の基台部２２，２２間の隙間２ｇより短くされていることに留意されたい（図２（ａ）及び図２（ｂ）を参照）。これにより、運搬用台車３がクレーン本体２の真下にまで進入可能である。この台車３の構造は、本装置１を用いた後述する補修方法を実施する上で大変重要となる。 It should be noted that the width 3w of the transport carriage 3 in the water channel width direction is shorter than the gap 2g between the base portions 22 and 22 of the crane body 2 (FIGS. 2A and 2B). See). As a result, the transport carriage 3 can enter just below the crane body 2. The structure of the carriage 3 is very important in carrying out a repair method described later using the apparatus 1.

クレーン本体２における水平支持部２３と支柱部２１との間の接続部には、水路側壁Ｗ，Ｗ間の距離Ｃｇに対応して、支柱部２１，２１間及び基台部２２，２２間の距離２ｇを調節可能な調節部２８が設けられる。図１では、調節部２８の例示として、水平支持部２３と、支持部２１の上部２１ｔとが互いに当接できるように板状となっており、これらの板には距離２ｇの方向に沿って調整孔２８ｈが複数設けられた構造を成す。これらの調整孔２８ｈのいずれかの位置に水平支持部２３と支持部２１とを締結するためのボルト（図２（ａ）中、２８ｂを参照）を一方から挿通し、他方からナット（図２（ａ）中、２８ｎを参照）で固定することによって、距離２ｇを所望の長さに調節することができる。 The connecting portion between the horizontal support portion 23 and the column portion 21 in the crane body 2 corresponds to the distance Cg between the channel side walls W and W and between the column portions 21 and 21 and between the base portions 22 and 22. An adjustment unit 28 capable of adjusting the distance 2g is provided. In FIG. 1, as an example of the adjustment unit 28, the horizontal support portion 23 and the upper portion 21 t of the support portion 21 have a plate shape so that they can contact each other, and these plates are along the direction of a distance 2 g. The structure is provided with a plurality of adjustment holes 28h. A bolt (see 28b in FIG. 2A) for fastening the horizontal support portion 23 and the support portion 21 is inserted into one of these adjustment holes 28h from one side, and a nut (see FIG. 2). (See 28n in (a)), the distance 2g can be adjusted to a desired length.

また、運搬用台車３の枠体３２のうち、水路Ｃを跨ぐように置かれた一対の枠体３２ａ，３２ａには、図２（ｂ）に示すように、幅調節部３５が枠体３２ａ，３２ａに沿って取り付けられており、これにより、幅調節部３５の長さ方向に複数設けられた調整孔３５ｈに図示しないボルト・ナットを取り付けて、枠体３２の幅方向の長さ３ｗを水路Ｃの隙間Ｃｇに対応した所望の長さ（隙間Ｃｇよりやや大きく、かつ、クレーン本体２の支柱部２１（基台部２２）間の隙間２ｇより小さい長さ）に設定することが可能となる（図２（ａ）も参照）。 Moreover, as shown in FIG.2 (b), as shown in FIG.2 (b), as for a pair of frame 32a, 32a placed so that the water channel C may be straddled among the frames 32 of the conveyance trolley 3, the frame 32a. , 32a, and bolts and nuts (not shown) are attached to a plurality of adjustment holes 35h provided in the length direction of the width adjusting portion 35, thereby reducing the length 3w of the frame body 32 in the width direction. It is possible to set a desired length corresponding to the gap Cg of the water channel C (a length slightly larger than the gap Cg and smaller than the gap 2g between the column portions 21 (base portions 22) of the crane body 2). (See also FIG. 2 (a)).

また、クレーン本体２又は運搬用台車３の少なくとも一方（図示の実施例では双方）には、クレーン本体２又は運搬用台車３の一部又は全部が水路Ｃ内に落下することを防止する落下防止装置４１，４２が設けられていることが好ましい。 Further, at least one of the crane main body 2 or the transport carriage 3 (both in the illustrated embodiment) prevents the crane main body 2 or the transport carriage 3 from dropping into the water channel C. Devices 41 and 42 are preferably provided.

ここで、クレーン本体２側の落下防止装置４１は、例えば、水路Ｃ両側に置かれた夫々の基台部２２，２２の長手方向の一端（前方端）近くに設けられており、基台部２２の内側に一旦延び、その後、水路Ｃの底に向かって延びた腕部４１ａと、腕部４１ａの下端に回転自在に設けられかつ水路側壁Ｗの側面Ｗｓに沿って走行可能なガイドローラー４１ｂと、を備える。 Here, the fall prevention device 41 on the crane body 2 side is provided, for example, near one end (front end) in the longitudinal direction of each base portion 22, 22 placed on both sides of the water channel C. 22 is extended to the inside of the water channel C, and then extended toward the bottom of the water channel C. The guide roller 41b is provided rotatably at the lower end of the arm portion 41a and can travel along the side surface Ws of the water channel side wall W. And comprising.

一方、運搬用台車３側の落下防止装置４２は、枠体３２のうち、水路側壁Ｗの側面Ｗｓとは直交する（つまり、図１中の水路Ｃを跨ぐように矢印方向の前方及び後方に置かれた）一対の枠体３２ａ，３２ａのそれぞれに設けられた一対の腕部４２ａと、腕部４２ａの下端に回転自在に設けられかつ水路側壁Ｗの側面Ｗｓに沿って走行可能なガイドローラー４２ｂと、を備える。 On the other hand, the fall prevention device 42 on the transport carriage 3 side is orthogonal to the side surface Ws of the water channel side wall W in the frame 32 (that is, forward and rearward in the arrow direction so as to straddle the water channel C in FIG. 1). A pair of arm portions 42a provided on each of the pair of frame bodies 32a and 32a, and a guide roller rotatably provided at the lower end of the arm portion 42a and capable of traveling along the side surface Ws of the water channel side wall W. 42b.

このような落下防止装置４１，４２を設けることにより、クレーン本体２や運搬用台車３を水路Ｃの長手方向に沿って走行させる際に、本体用車輪２７，２７や台車用車輪３３，３３の横方向（つまり、水路Ｃの長手方向と直交する方向）の移動が所定範囲に規制されるため、本体用車輪２７，２７や台車用車輪３３，３３を含めたクレーン本体２や運搬用台車３の一部又は全部が水路側壁Ｗの上面Ｗｔから外れて（脱輪して）、水路Ｃや水路側壁Ｗ外側の水路脇Ａ１や田圃Ａ２や農地Ａ３へ落下することを防止することができる。 By providing such fall prevention devices 41 and 42, when the crane main body 2 and the transport carriage 3 are run along the longitudinal direction of the water channel C, the main body wheels 27 and 27 and the truck wheels 33 and 33 Since the movement in the lateral direction (that is, the direction orthogonal to the longitudinal direction of the water channel C) is restricted to a predetermined range, the crane main body 2 including the main body wheels 27 and 27 and the bogie wheels 33 and 33, and the transport bogie 3 Can be prevented from falling off the upper surface Wt of the water channel side wall W (falling off) and falling to the water channel A1, the rice field A2, and the farmland A3 outside the water channel C and the water channel side wall W.

なお、クレーン本体２側の落下防止装置４１は、基台部２２，２２の長手方向の一端（前方端）側にだけ設けられることが好ましい。後述の補修方法を実施するにあたり、基台部２２の別の一端（後方端）近くでは、水路Ｃの内側に突出した落下防止装置４１が設けられていないため、運搬用台車３の走行路上に障害物は存在せず、運搬用台車３が後方端からクレーン本体２内に進入し、クレーン本体２の真下位置まで走行できるようになる。 In addition, it is preferable that the fall prevention device 41 on the crane body 2 side is provided only on one end (front end) side in the longitudinal direction of the base portions 22 and 22. In carrying out the repair method described later, near the other end (rear end) of the base portion 22, the fall prevention device 41 protruding inside the water channel C is not provided. There is no obstacle, and the transport carriage 3 enters the crane body 2 from the rear end and can travel to a position directly below the crane body 2.

（補修方法の説明）
次に、以上説明した本発明の補修装置１を用いて既存水路Ｃを補修する方法について、図４を参照しながら説明する。なお、図４は本発明の補修方法の各工程Ｓ１〜Ｓ７を説明したフローチャートである。なお、本補修方法を現場の既存水路Ｃで実施する際の事前準備として、クレーン本体２、運搬用台車３、パネル材Ｐ等の機材をトラック等の大型車両（図示せず）で現場近くの道路脇まで運び込んでおく必要がある。 (Explanation of repair method)
Next, a method for repairing the existing water channel C using the repair device 1 of the present invention described above will be described with reference to FIG. FIG. 4 is a flowchart illustrating the steps S1 to S7 of the repair method of the present invention. In addition, as a pre-preparation when this repair method is carried out in the existing water channel C at the site, equipment such as the crane main body 2, the carriage 3 and the panel material P can be placed near the site using a large vehicle (not shown) such as a truck. It is necessary to carry it to the side of the road.

また、図３（ａ）は、本補修方法に従って、作業者Ｏが水路Ｃ内で補修作業を行う様子と水路Ｃの断面構造の概略を示す。水路Ｃは、その両側の水路脇Ａ１（の土手）との境界を区画する水路側壁Ｗと、底部Ｗｃと、から構成された上方が開口した有底のコの字状断面構造を成す。水路側壁Ｗは、上面Ｗｔ及び側面（内側側面）Ｗｓを有した笠板Ｗａと、鋼矢板等の側壁本体Ｗｂと、から通常、構成される。経年劣化等により、側壁本体Ｗｂには、錆、孔、ひび割れ等の劣化箇所Ｂが発生し、補修が必要な補修箇所となる。 FIG. 3A shows an outline of the cross-sectional structure of the water channel C and how the worker O performs the repair work in the water channel C according to the present repair method. The water channel C has a bottomed U-shaped cross-sectional structure having an open top formed by a water channel side wall W that partitions the boundary with the water channel side A1 (the bank) on both sides thereof and a bottom portion Wc. The water channel side wall W is usually composed of a cap plate Wa having an upper surface Wt and a side surface (inner side surface) Ws, and a side wall body Wb such as a steel sheet pile. Due to aged deterioration or the like, a deteriorated portion B such as rust, hole, crack or the like is generated in the side wall main body Wb and becomes a repaired portion requiring repair.

本補修方法では、先ず、クレーン本体２を水路側壁Ｗ上の任意の位置に立設する（本体立設工程Ｓ１、図４も参照）。より具体的には、道路脇から水路側壁Ｗにクレーン本体２を運び、この本体２を水路側壁Ｗの上面Ｗｔに垂直に立設させる。 In this repair method, first, the crane main body 2 is erected at an arbitrary position on the water channel side wall W (see also the main body erection step S1 and FIG. 4). More specifically, the crane main body 2 is carried from the side of the road to the water channel side wall W, and the main body 2 is erected vertically on the upper surface Wt of the water channel side wall W.

工程Ｓ１の実行後、水路側壁Ｗに沿って本体用車輪２７を転動させてクレーン本体２を補修箇所Ｂまで移動（水平移動）させる（本体移動工程Ｓ２）。なお、クレーン本体２の高さ及び幅は、それぞれ、約３〜５ｍ及び約１〜３ｍ（水路Ｃの幅Ｃｇに対応して調整）であり、簡素なＨ形鋼で形作られているため従来の重機に比べて格段に軽量であり、複数の作業者Ｏによる人力だけで、水路側壁Ｗ上の補修箇所Ｂまで容易に水平移動させることが可能となる。 After execution of process S1, wheel 27 for main bodies is rolled along waterway side wall W, and crane main part 2 is moved to repair location B (horizontal movement) (main body movement process S2). The height and width of the crane body 2 are about 3 to 5 m and about 1 to 3 m (adjusted according to the width Cg of the water channel C), respectively, and are conventionally formed with simple H-shaped steel. It is much lighter than the heavy machinery, and can be easily moved horizontally to the repair location B on the water channel side wall W only by human power by a plurality of workers O.

工程Ｓ２の実行後、運搬用台車３（より詳しくは、台車用車輪３３）を水路側壁Ｗ上の任意の位置に載置する（台車載置工程Ｓ３）。その後、パネル材Ｐを運搬用台車３に積載する（パネル材積載工程Ｓ４）。その後、水路側壁Ｗに沿って台車用車輪３３を転動させて運搬用台車３を前述の補修箇所Ｂ近くの位置に立設したクレーン本体２の真下に進入させる（台車進入工程Ｓ５）。 After the execution of the step S2, the transport carriage 3 (more specifically, the carriage wheel 33) is placed at an arbitrary position on the water channel side wall W (on-vehicle placement step S3). Thereafter, the panel material P is loaded on the transport carriage 3 (panel material loading step S4). Thereafter, the cart wheel 33 is rolled along the water channel side wall W to cause the transport cart 3 to enter just below the crane body 2 erected at the position near the above-described repair location B (trolley entry step S5).

上記工程Ｓ１〜Ｓ５の実行によって、クレーン本体２と運搬用台車３とが補修のための望ましい位置に配置できたので、作業者Ｏは、図３（ａ）及び後述の説明に示すように、被装着部材であるパネル材Ｐの取付・接着を開始できるようになる。 Since the crane main body 2 and the carriage 3 can be arranged at a desired position for repair by performing the steps S1 to S5, the operator O, as shown in FIG. Attachment and adhesion of the panel material P, which is a member to be mounted, can be started.

つまり、クレーン本体２の保持部２５（図３（ａ）では、揚重機２４に懸架されているチェーン２５ｂの末端に接続されたフック部２５ａ及びロープ２５ｃ）にパネル材Ｐを取り付けて、操作部２６を操作して、パネル材Ｐが補修箇所Ｂに接近するように保持部２５及び揚重機２４を移動させる（パネル材操作工程Ｓ６）。具体的には、保持部２５の垂直移動によって保持部２５に取り付けられたパネル材Ｐも水路Ｃの上下に移動させることができ、揚重機２４（及び揚重機２４に吊り下げられた保持部２５）の水平移動により、保持部２５に取り付けられたパネル材Ｐも水平移動させることができる。 That is, the panel material P is attached to the holding portion 25 of the crane body 2 (in FIG. 3A, the hook portion 25a and the rope 25c connected to the end of the chain 25b suspended from the lifting machine 24), and the operation portion 26 is operated and the holding | maintenance part 25 and the lifting machine 24 are moved so that the panel material P may approach the repair location B (panel material operation process S6). Specifically, the panel material P attached to the holding unit 25 by the vertical movement of the holding unit 25 can also be moved up and down the water channel C, and the lifting machine 24 (and the holding unit 25 suspended from the lifting machine 24). ) Can be moved horizontally as well.

すなわち、上記工程Ｓ６の実行後は、例えば、パネル材Ｐは水路Ｃ内の補修箇所Ｂに近接した位置に配置・一時固定できた状態になる。このような状態から、パネル材Ｐを補修箇所Ｂに接続して補修を行う（補修工程Ｓ７）。 That is, after execution of the above-described step S6, for example, the panel material P is in a state where it can be arranged and temporarily fixed at a position close to the repair location B in the water channel C. From such a state, the panel material P is connected to the repair location B for repair (repair process S7).

これにて、通常、長い水路Ｃ上のある一つの補修箇所Ｂでの補修を終えることができるが、長時間の使用により、通常、水路Ｃ上のそれ以外の複数の劣化箇所Ｂで補修が必要となる。そのような（別の補修箇所Ｂでの補修が必要な）場合には、毎回、上述した本体立設工程Ｓ１乃至補修工程Ｓ７を繰り返すことで、積載車両停車位置や道路から著しく離れた水路Ｃ上の奥まった所でも、クレーン本体２と運搬用台車３を利用するだけでパネル材Ｐを容易く安全に運び込み、補修箇所Ｂに接合することができるのである。従って、本補修方法では、従来の補修方法で必須であった重機の利用をすることも、重機を水路Ｃに沿って移動させたり、仮置いたりするための作業運搬路を水路Ｃ脇に沿って造設・確保していくことも不要となる。 With this, the repair at one repair point B on the long water channel C can be completed normally, but the repair is usually performed at a plurality of other deteriorated points B on the water channel C by using for a long time. Necessary. In such a case (repair at another repair point B is necessary), the main body erection process S1 to the repair process S7 are repeated every time, so that the waterway C significantly separated from the loading vehicle stop position and the road. The panel material P can be easily and safely transported and joined to the repair location B simply by using the crane main body 2 and the transport carriage 3 even in the deeper place above. Therefore, in this repair method, the use of heavy machinery, which was essential in the conventional repair method, can be used along the water channel C along the work transportation path for moving the heavy machinery along the water channel C or temporarily placing it. It is no longer necessary to build and secure the system.

なお、本発明の補修方法は、さらに、以下に説明する工程Ｓ１１，Ｓ１２，Ｓ１３も含んでいることが好ましい。すなわち、図３（ｂ）に示すように、本方法に利用するパネル材Ｐの一方の表面Ｐｓ_２には、予め補強材Ｐｂ（好ましくは、複数の鉄筋を格子状に組んだ構造）を配設しておく（剛性強化工程Ｓ１１）。そして、図３（ａ）に示すように、補修工程Ｓ７より前の段階で、補修箇所Ｂの近くの（箇所Ｂの上方に位置する）水路側壁Ｗの上面Ｗｔに、補修箇所Ｂまで到達する貫通孔Ｈを設ける（穿孔工程Ｓ１２）。 In addition, it is preferable that the repair method of this invention also contains process S11, S12, S13 demonstrated below. That is, as shown in FIG. 3B, a reinforcing material Pb (preferably a structure in which a plurality of reinforcing bars are assembled in a lattice shape) is arranged on one surface Ps ₂ of the panel material P used in this method. (Stiffening step S11). And as shown to Fig.3 (a), it reaches the repair location B on the upper surface Wt of the water channel side wall W near the repair location B (located above the location B) in the stage before the repair step S7. A through hole H is provided (drilling step S12).

このような好適な事前処理工程Ｓ１１，Ｓ１２を実行しておけば、補修工程Ｓ７では、パネル材Ｐの内表面Ｐｓ_２側を補修箇所Ｂに当接させつつ、貫通孔Ｈから補修箇所Ｂとパネル材Ｐとの隙間にセメント又はモルタル、その他の結合硬化剤を流し込みことにより、補修箇所Ｂとパネル材Ｐとを確実かつ堅固に接合することができる（工程Ｓ１３）。これにより、補強材Ｐｂ（鉄筋）付きパネル材Ｐで接合・補修された補修箇所Ｂを含んだ修復部分では、補修前に比べると、その剛性や強度を大幅増強することができる。 If running such suitable preprocessing steps S11, S12, the repairing process S7, while the inner surface Ps ₂ side of the panel material P is in contact with the repaired portion B, a repaired portion B from the through-hole H By pouring cement, mortar, or other bonding hardener into the gap with the panel material P, the repaired portion B and the panel material P can be reliably and firmly joined (step S13). Thereby, the rigidity and strength of the repaired part including the repaired part B joined and repaired by the panel material P with the reinforcing material Pb (reinforcing bar) can be greatly increased as compared to before repairing.

本発明によれば、水路Ｃ上をそれぞれ別々に走行可能で簡素かつ軽量なクレーン本体と運搬用台車を利用するだけ補修作業が行えるため、従来の方法では必須であった重機の導入や作業用運搬路の造設が不要になり、上述した様々なメリットを補修請負業者や水路脇の農地所有者に提供するのである。このように、本発明は、産業上の利用価値及び産業上の利用可能性が非常に高い。 According to the present invention, since repair work can be performed only by using a simple and lightweight crane body and a transport carriage that can run separately on the water channel C, the introduction and operation of heavy machinery, which is essential in the conventional method, can be performed. This eliminates the need for construction of a transport channel and provides the various advantages described above to repair contractors and farmland owners alongside waterways. Thus, the present invention has a very high industrial utility value and industrial applicability.
