Description
本発明は、線状構造物の構築予定領域に沿って移動しながら、線状構造物の施工を行う線状構造物構築作業システム、及び線状構造物構築作業システムを用いた線状構造物の構築方法に関する。 The present invention is a linear structure construction work system for constructing a linear structure while moving along a planned construction area of the linear structure, and a linear structure using the linear structure construction work system. Regarding how to build.
従来より、擁壁や遮音壁等の線状構造物を構築する場合、線状構造物の横断面より大きい内側空間を有する作業用建屋や移動式足場を施工現場に搬入し、これらを施工現場内に位置する線状構造物の構築予定領域における長手方向に移動させつつ、その内側空間に設けられた作業スペースを利用して、線状構造物の施工を行っている。 Conventionally, when constructing a linear structure such as a retaining wall or a sound insulating wall, a work building or a mobile scaffold having an inner space larger than the cross section of the linear structure is brought into the construction site, and these are carried into the construction site. While moving in the longitudinal direction in the planned construction area of the linear structure located in, the linear structure is constructed by utilizing the work space provided in the inner space.
例えば、特許文献１では、擁壁工事用移動足場を利用して擁壁を構築する方法が開示されている。擁壁工事用移動足場は、構築予定の擁壁の表裏に一対の足場フレームを配置するとともに両者を連結梁で連結して一対の足場フレームで囲まれた内部空間を形成し、足場フレームの内部空間と対向する側面各々に作業通路および昇降階段を設けた構造を有している。 For example, Patent Document 1 discloses a method of constructing a retaining wall by using a moving scaffold for retaining wall construction. For the moving scaffolding for retaining wall construction, a pair of scaffolding frames are placed on the front and back of the retaining wall to be constructed, and both are connected by connecting beams to form an internal space surrounded by the pair of scaffolding frames, and the inside of the scaffolding frame is formed. It has a structure in which a work passage and an ascending / descending staircase are provided on each side surface facing the space.
そして、このような構造の擁壁工事用移動足場の内部空間を利用して、擁壁の構築予定領域を区割りした複数の工事区域のうちの一工区で施工を行う。こののち、クレーン等を用いて擁壁工事用移動足場を移動させ、移動した擁壁工事用移動足場を、次の工区に設置する。これらの作業をすべての工事区域で施工を行うまで繰り返し行い、長大な擁壁を構築している。 Then, using the internal space of the moving scaffold for retaining wall construction having such a structure, the construction is carried out in one of a plurality of construction areas in which the planned construction area of the retaining wall is divided. After that, the moving scaffolding for retaining wall construction is moved using a crane or the like, and the moved moving scaffolding for retaining wall construction is installed in the next construction area. These operations are repeated until construction is carried out in all construction areas, and a long retaining wall is constructed.
特許文献１では、擁壁工事用移動足場を解体することなくそのまま移動させることができることから、一工区ごとに全面足場の組立及び解台を繰り返しながら擁壁の施工を実施するといった手間を省略でき、工期を大幅に短縮できる。また、擁壁工事用移動足場の外周面を養生シートで覆うと、全天候対策を取ることもできる。 In Patent Document 1, since the moving scaffold for retaining wall construction can be moved as it is without dismantling, it is possible to omit the trouble of constructing the retaining wall while repeating the assembly and dismantling of the entire scaffold for each construction zone. , The construction period can be shortened significantly. In addition, if the outer peripheral surface of the moving scaffold for retaining wall construction is covered with a curing sheet, all-weather measures can be taken.
しかし、擁壁工事用移動足場の内側空間は狭隘かつ低空頭となりやすく、別途クレーン等の揚重装置を手配する必要がある等、建設材料や工具等の揚重作業に課題が生じる。また、施工現場が供用中の道路や既設構造物に隣接している場合には、施工現場外への建設資材及び建設廃材の落下防止対策や施工時に発生する粉塵対策等、施工現場周辺の住環境を保全する対策が必要となる。 However, the space inside the moving scaffold for retaining wall construction is narrow and tends to have a low head, and it is necessary to separately arrange a lifting device such as a crane, which causes problems in lifting work of construction materials and tools. In addition, if the construction site is adjacent to an in-service road or existing structure, living around the construction site, such as measures to prevent the construction materials and construction waste from falling outside the construction site and measures to prevent dust generated during construction, etc. Measures to protect the environment are required.
本発明は、かかる課題に鑑みなされたものであって、その主な目的は、施工現場周辺の住環境を保全しながら、作業効率を向上することの可能な、線状構造物構築作業システム及び線状構造物の構築方法を提供することである。 The present invention has been made in view of such a problem, and a main object thereof is a linear structure construction work system capable of improving work efficiency while preserving the living environment around the construction site. It is to provide a method of constructing a linear structure.
かかる目的を達成するため、本発明の線状構造物構築作業システムは、線状構造物の構築予定領域を跨いで配置され、内部空間に作業スペースが形成されるとともに走行体を備える作業用建屋と、前記構築予定領域の長手方向に沿って設けられ、前記走行体の走行方向を案内する走行ガイドと、を備え、前記作業用建屋は、走行方向に平行な両側面の外側が、少なくとも水密性及び気密性を有する防護パネルで被覆され、前記作業用建屋の内面には、作業用足場と天井クレーンとが設けられていることを特徴とする。 In order to achieve such an object, the linear structure construction work system of the present invention is arranged across the planned construction area of the linear structure, a work space is formed in the internal space, and a work building provided with a traveling body. The work building is provided with a traveling guide provided along the longitudinal direction of the planned construction area and guiding the traveling direction of the traveling body, and the work building is at least watertight on the outside of both side surfaces parallel to the traveling direction. It is covered with a protective panel having property and airtightness, and is characterized in that a work scaffold and an overhead crane are provided on the inner surface of the work building.
本発明の線状構造物構築作業システムによれば、作業用建屋には作業スペースに面して作業用足場と天井クレーンが設けられていることから、揚重装置等を別途手配する必要が無く、狭隘な作業スペースを有効に活用しながら、線状構造物の施工を行うことができる。また、施工現場におけるクレーンを用いた揚重作業が、作業用建屋内への資材搬入時のみであるため、吊荷の接触事故が生じにくく安全性を向上することが可能となる。 According to the linear structure construction work system of the present invention, since the work building is provided with a work scaffolding and an overhead crane facing the work space, it is not necessary to separately arrange a lifting device or the like. , It is possible to construct linear structures while effectively utilizing the narrow work space. Further, since the lifting work using a crane at the construction site is performed only when the material is brought into the work building, it is possible to improve the safety by preventing the contact accident of the suspended load.
また、作業用建屋に形成された作業スペースは、防護パネルで防護されていることから、施工中に作業スペースから施工現場外に向けて、建設工具や建設資材もしくは建設廃材等が落下したり、粉塵やコンクリートのレイタンス処理水が飛散する現象を抑制でき、施工現場周辺の住環境を保全することが可能となる。 In addition, since the work space formed in the work building is protected by a protective panel, construction tools, construction materials, construction waste materials, etc. may fall from the work space to the outside of the construction site during construction. It is possible to suppress the phenomenon of dust and concrete latency-treated water being scattered, and to preserve the living environment around the construction site.
本発明の線状構造物構築作業システムは、前記作業用建屋が、前記線状構造物を構築するために実施する作業工程の数量と同数設けられていることを特徴とする。 The linear structure construction work system of the present invention is characterized in that the work building is provided in the same number as the number of work steps to be carried out for constructing the linear structure.
本発明の線状構造物構築作業システムによれば、前記構造物を構築するために実施する作業工程の数量と、同数の作業用建屋が設けることから、実施する作業を作業用建屋ごとで分担することができ、分担された作業を並行して実施しながら線状構造物を構築することが可能となる。 According to the linear structure construction work system of the present invention, the number of work steps to be carried out for constructing the structure and the same number of work buildings are provided, so that the work to be carried out is shared among the work buildings. It is possible to construct a linear structure while carrying out the shared work in parallel.
また、作業用建屋ごとに、分担された作業に必要な機能及び施工現場周辺の住環境保護に必要な機能を装備して、線状構造物構築作業システムの多機能集約化を図ることもでき、これにより、線状構造物を構築する際の作業性が大幅に向上し、工期削減及び工費短縮に寄与することが可能となる。 In addition, each work building can be equipped with the functions required for shared work and the functions required for protecting the living environment around the construction site, and the linear structure construction work system can be integrated into multiple functions. As a result, workability when constructing a linear structure is greatly improved, and it becomes possible to contribute to reduction of construction period and construction cost.
本発明の線状構造物構築作業システムは、前記線状構造物が、鉄筋組立作業、型枠組立作業、及びコンクリート打設作業の、少なくとも３つの作業工程を経て構築される鉄筋コンクリート造よりなり、前記３つの作業工程をそれぞれ分担して実施する、３台の前記作業用建屋が設けられるとともに、前記コンクリート打設作業を実施する前記作業用建屋には、コンクリートの供給配管が設置されていることを特徴とする。 The linear structure construction work system of the present invention comprises a reinforced concrete structure in which the linear structure is constructed through at least three work steps of a reinforcing bar assembly work, a formwork assembly work, and a concrete placing work. The three work buildings that share and carry out the three work processes are provided, and the concrete supply pipes are installed in the work building that carries out the concrete placing work. It is characterized by.
また、本発明の線状構造物の構築方法は、本発明の線状構造物構築作業システムを用いた線状構造物の構築方法であって、前記走行ガイド上に、鉄筋組立作業を実施する前記作業用建屋、鉄筋組立作業が終了している位置で型枠組立作業を実施する前記作業用建屋、型枠組立作業が終了している位置でコンクリート打設作業を実施する前記作業用建屋、を配置し、前記作業用建屋各々で、分担された作業を実施することを特徴とする。 Further, the method for constructing a linear structure of the present invention is a method for constructing a linear structure using the linear structure construction work system of the present invention, and a reinforcing bar assembly work is carried out on the traveling guide. The work building, the work building where the formwork assembly work is carried out at the position where the reinforcing bar assembly work is completed, the work building where the concrete placing work is carried out at the position where the formwork assembly work is completed, Is arranged, and each of the work buildings is characterized in that the shared work is carried out.
本発明の線状構造物構築作業システム及び線状構造物の構築方法によれば、３台の作業用建屋ごとで、鉄筋組立作業、型枠組立作業及びコンクリート打設作業を並行して実施し、各作業の終了後には作業用建屋を次の施工位置に移動して、分担された同じ作業を繰り返し行うことができる。これにより、１つの作業スペースで複数の作業を行う場合と比較して、作業に必要な工具の入れ替え等の工程を省略でき、施工性を向上しつつ工期を大幅に短縮することが可能となる。 According to the linear structure construction work system and the linear structure construction method of the present invention, the reinforcing bar assembly work, the formwork assembly work, and the concrete placing work are carried out in parallel for each of the three work buildings. After each work is completed, the work building can be moved to the next construction position and the same shared work can be repeated. As a result, compared to the case where a plurality of works are performed in one work space, steps such as replacement of tools required for the work can be omitted, and the work period can be significantly shortened while improving workability. ..
本発明によれば、作業用足場と天井クレーンが設けられた作業スペースを防護パネルで保護した作業用建屋を備えることから、施工現場周辺の住環境を保全しながら、狭隘な作業スペースでの線状構造物の作業効率を向上することが可能となる。 According to the present invention, since a work building in which a work space provided with a work scaffold and an overhead crane is protected by a protective panel is provided, a line in a narrow work space is provided while preserving the living environment around the construction site. It is possible to improve the work efficiency of the shaped structure.
本発明の線状構造物構築作業システムは、擁壁や遮音壁等の線状構造物を地上もしくは地中を開削して施工する際に適したシステムであり、作業用建屋を施工現場内に位置する線状構造物の構築予定領域における長手方向に沿って移動させながら、内側空間に形成された作業スペースを利用して、線状構造物を構築するものである。 The linear structure construction work system of the present invention is a system suitable for excavating a linear structure such as a retaining wall or a sound insulating wall on the ground or in the ground, and a work building is located in the construction site. The linear structure is constructed by utilizing the work space formed in the inner space while moving along the longitudinal direction in the planned construction area of the linear structure.
本実施の形態では、図１（ａ）（ｂ）で示すような、複数の鋼管杭Ｐを一列に配置して形成した基礎上に、鉄筋コンクリート造の壁体Ｗを構築する場合を事例に挙げ、以下に詳細を説明する。 In the present embodiment, a case where a reinforced concrete wall body W is constructed on a foundation formed by arranging a plurality of steel pipe piles P in a row as shown in FIGS. 1A and 1B is taken as an example. , The details will be described below.
≪≪線状構造物構築作業システム≫≫
図１（ａ）で示すように、線状構造物構築作業システム１００は、壁体Ｗの構築予定領域Ｅに跨って配置される３台の作業用建屋１０と、作業用建屋１０の走行方向を案内する走行ガイド２０と、図５で示すような、作業用建屋１０を牽引する牽引機構３０とを有している。なお、施工現場内に位置する壁体Ｗの構築予定領域Ｅには、壁体Ｗの基礎となる複数の鋼管杭Ｐが列をなして埋設されている。
≪≪Linear structure construction work system≫≫
As shown in FIG. 1A, the linear structure construction work system 100 has three work buildings 10 arranged across the planned construction area E of the wall body W, and the traveling directions of the work buildings 10. It has a traveling guide 20 for guiding the vehicle and a towing mechanism 30 for pulling the work building 10 as shown in FIG. A plurality of steel pipe piles P, which are the foundations of the wall body W, are buried in a row in the planned construction area E of the wall body W located in the construction site.
≪走行ガイド≫
走行ガイド２０は、図１（ａ）及び図２で示すように、壁体Ｗの構築予定領域Ｅに沿って設けられるもので、作業用建屋１０が移動するレール本体２１と、作業用建屋１０の逸走を抑制するストッパー２２とにより構成されている。
≪Running guide≫
As shown in FIGS. 1A and 2, the traveling guide 20 is provided along the planned construction area E of the wall body W, and the rail main body 21 to which the work building 10 moves and the work building 10 It is composed of a stopper 22 that suppresses the escape of the rail.
レール本体２１は、作業用建屋１０が載置された際に変形しない程度の強度を有するとともに、上面に凹部を有する長尺材が望ましく、本実施の形態では、軸線方向に接続した複数の溝形鋼を採用している。これらレール本体２１は、構築予定領域Ｅの長手方向両側それぞれに設置されるとともに、レール本体２１の端部には、ストッパー２２が配置されている。 The rail body 21 is preferably a long material having a recess on the upper surface while having a strength that does not deform when the work building 10 is placed. In the present embodiment, a plurality of grooves connected in the axial direction are desired. Shaped steel is used. These rail main bodies 21 are installed on both sides in the longitudinal direction of the planned construction area E, and stoppers 22 are arranged at the ends of the rail main bodies 21.
ストッパー２２は、レール本体２１上を走行する作業用建屋１０の逸走を防止できるものであれば、いずれ形状のものを採用してもよいが、本実施の形態では、レール本体２１の軸線方向に対して長手方向が直交して配置されるアングル材等の長尺鋼材を採用している。その配置位置は、側面をレール本体２１の端面に当接した状態で、鋼管杭Ｐと対向する端部が、溶接等の固着手段により鋼管杭Ｐの側面に固着されている。 The stopper 22 may have any shape as long as it can prevent the work building 10 traveling on the rail body 21 from escaping, but in the present embodiment, the stopper 22 is oriented in the axial direction of the rail body 21. On the other hand, long steel materials such as angle materials that are arranged orthogonally in the longitudinal direction are used. The arrangement position is such that the end portion facing the steel pipe pile P is fixed to the side surface of the steel pipe pile P by a fixing means such as welding while the side surface is in contact with the end face of the rail body 21.
こうしてストッパー２２にレール本体２１の端面を当接させることにより、作業用建屋１０がレール本体２１上を走行する際、レール本体２１の端部を越えて逸走しようとする挙動を抑制することができる。 By bringing the end face of the rail body 21 into contact with the stopper 22 in this way, when the work building 10 travels on the rail body 21, it is possible to suppress the behavior of trying to escape beyond the end of the rail body 21. ..
≪作業用建屋≫
作業用建屋１０は、図２で示すように、その内側空間が壁体Ｗを構築する際に使用する作業スペース１６となっており、建屋本体１１と、建屋本体１１の内部空間に設けられる作業用足場１７と、天井面に設けられる天井クレーン１８と、を有している。
≪Work building≫
As shown in FIG. 2, the work building 10 has a work space 16 whose inner space is used when constructing the wall body W, and is provided in the building main body 11 and the internal space of the building main body 11. It has a scaffolding 17 and an overhead crane 18 provided on the ceiling surface.
建屋本体１１は、図１（ｂ）及び図２で示すように、フレーム１２と、フレーム１２の側面を覆う防護パネル１１１、遮蔽カーテン１１２、及び通気性面材１１３を有している。 As shown in FIGS. 1 (b) and 2, the building main body 11 has a frame 12, a protective panel 111 that covers the side surface of the frame 12, a shielding curtain 112, and a breathable surface material 113.
フレーム１２は、図２で示すように、壁体Ｗの構築予定領域Ｅを挟んで一対の支柱１３を配置するとともに支柱１３の頭部どうしを連結梁１４で連結した門型ラーメン構造を、図１（ｂ）で示すように、構築予定領域Ｅの長手方向に間隔を設けて複数配置し、これらを連結桁１５で連結することにより形成されている。そして、このフレーム１２の内側が、壁体Ｗの構築に係る作業を実施するための作業スペース１６となっている。 As shown in FIG. 2, the frame 12 has a gate-shaped rigid frame structure in which a pair of columns 13 are arranged across a planned construction area E of the wall body W and the heads of the columns 13 are connected by connecting beams 14. As shown in 1 (b), a plurality of planned construction areas E are arranged at intervals in the longitudinal direction, and these are connected by a connecting girder 15. The inside of the frame 12 is a work space 16 for carrying out the work related to the construction of the wall body W.
また、図２で示すように、支柱１３の下端部には、連結桁１５の延在方向に回転する、例えばエンドレスコロや車輪等を備えた走行体１３１がベースプレート１３２を介して設けられている。これにより作業用建屋１０は、レール本体２１上を走行することが可能となっている。 Further, as shown in FIG. 2, a traveling body 131 having, for example, an endless roller or a wheel, which rotates in the extending direction of the connecting girder 15, is provided at the lower end of the support column 13 via the base plate 132. .. As a result, the work building 10 can travel on the rail body 21.
防護パネル１１１は、図２及び図３で示すように、フレーム１２の走行方向に平行な側面であって連結桁１５と支柱１３とにより囲まれる範囲を、外側から被覆するようにして設置されている。防護パネル１１１の材料は、少なくとも気密性及び水密性を有し、さらには壁体Ｗの構築作業時に使用する建設工具や建設資材が衝突した際に、破損しない程度の強度を有するものが好ましく、例えば、金属製パネルやカーボン積層ボード等が好適である。 As shown in FIGS. 2 and 3, the protective panel 111 is installed so as to cover the side surface of the frame 12 parallel to the traveling direction and surrounded by the connecting girder 15 and the support column 13 from the outside. There is. The material of the protective panel 111 preferably has at least airtightness and watertightness, and is strong enough not to be damaged when a construction tool or construction material used during the construction work of the wall body W collides with the material. For example, a metal panel, a carbon laminated board, or the like is suitable.
これにより、作業用建屋１０内に設けた作業スペース１６から施工現場外に向けて、壁体Ｗの構築時に使用する建設機械や工具、建設資材もしくは建設廃材等が落下したり、粉塵やコンクリートのレイタンス処理水が飛散する現象を抑制することが可能となる。 As a result, the construction machinery, tools, construction materials, construction waste materials, etc. used when constructing the wall body W may fall from the work space 16 provided in the work building 10 to the outside of the construction site, or dust or concrete. It is possible to suppress the phenomenon that the latency-treated water is scattered.
遮蔽カーテン１１２は、図２及び図３で示すように、フレーム１２の走行方向に平行な側面であって走行体１３１より内側に、隣り合う支柱１３のベースプレート１３２を架け渡すようにして設置している。遮蔽カーテン１１２の材料は、気密性及び水密性を有し、かつ垂下げられた際の下端部がレール本体２１の設置面に沿う程度に可撓性を有する材料であればいずれを採用してもよく、本実施の形態では、ゴムシートを採用している。 As shown in FIGS. 2 and 3, the shielding curtain 112 is installed so as to bridge the base plate 132 of the adjacent columns 13 on the side surface parallel to the traveling direction of the frame 12 and inside the traveling body 131. There is. As the material of the shielding curtain 112, any material is adopted as long as it has airtightness and watertightness and the lower end portion when hung is flexible enough to be along the installation surface of the rail body 21. Also, in this embodiment, a rubber sheet is used.
これにより、防護パネル１１１の下端部とレール本体２１の設置面との間に形成される隙間が塞がれるため、作業スペース１６から施工現場外に向かって、セメントが混じった排水やノロ等が漏出する現象を防止できる。 As a result, the gap formed between the lower end of the protective panel 111 and the installation surface of the rail body 21 is closed, so that drainage or slag mixed with cement flows from the work space 16 to the outside of the construction site. The phenomenon of leakage can be prevented.
なお、本実施の形態では、遮蔽カーテン１１２の下端部をレール本体２１の設置面に沿わせて屈曲させているが、必ずしもこれに限定するものではない。例えば、レール本体２１の設置面であって、構築予定領域Ｅに面する側面に沿ってトレンチを形成し、このトレンチ内に下端部が入り込むようにして、遮蔽カーテン１１２を垂下させてもよい。 In the present embodiment, the lower end of the shielding curtain 112 is bent along the installation surface of the rail body 21, but the present invention is not necessarily limited to this. For example, the shielding curtain 112 may be hung down by forming a trench along the side surface of the rail body 21 facing the planned construction area E and allowing the lower end portion to enter the trench.
通気性面材１１３は、図２及び図４で示すように、フレーム１２の天井部であって連結桁１５と連結梁１４とにより囲まれる範囲を、外側から被覆するようにして設置されている。通気性面材１１３の材料は、網鋼板やルーバー等、通気性を有する材料であれば、いずれを採用してもよいが、本実施の形態では、目合い１ｍｍ程度のメッシュシートを採用している。 As shown in FIGS. 2 and 4, the breathable surface material 113 is installed so as to cover the ceiling portion of the frame 12 surrounded by the connecting girder 15 and the connecting beam 14 from the outside. .. As the material of the breathable face material 113, any material having breathability such as a mesh steel plate or a louver may be used, but in the present embodiment, a mesh sheet having a mesh size of about 1 mm is used. There is.
これにより、作業用建屋１０に流入した風は通気性面材１１３から抜けていくため、強風に晒されても作業用建屋１０が浮き上がる等のレール本体２１から逸脱する現象を抑制することができる。なお、通気性面材１１３にルーバーを用いると、作業用建屋を全天候型の建屋とすることが可能となる。 As a result, the wind that has flowed into the work building 10 escapes from the breathable surface material 113, so that it is possible to suppress a phenomenon in which the work building 10 floats up from the rail body 21 even when exposed to strong wind. .. If a louver is used for the breathable surface material 113, the work building can be made into an all-weather building.
また、図１（ａ）（ｂ）で示すように、フレーム１２は連結材１１４や張出し材１１５を介して鋼管杭Ｐに連結されており、台風や暴風等の悪天候時にあっても、通気性面材１１３と相まって作業用建屋１０が横転するような現象を防止することが可能となる。連結材１１４はワイヤーやチェーン等いずれの線状材を採用してもよく、また、連結材１１４を連結する位置は、上記の鋼管杭Ｐや張出し材１１５に限定されることなく、施工現場内の不動物であれば、いずれに連結してもよい。 Further, as shown in FIGS. 1A and 1B, the frame 12 is connected to the steel pipe pile P via the connecting material 114 and the overhanging material 115, and is breathable even in bad weather such as a typhoon or a storm. Combined with the face material 113, it is possible to prevent a phenomenon in which the work building 10 rolls over. Any linear material such as a wire or a chain may be used for the connecting material 114, and the position where the connecting material 114 is connected is not limited to the steel pipe pile P or the overhanging material 115, and is within the construction site. If it is a non-animal, it may be connected to any of them.
なお、張出し材１１５は、施工対象領域Ｅに鉄筋かごＳや型枠Ｆが設置されることにより、連結材１１４を鋼管杭Ｐに設置できない場合や、施工現場内に鋼管杭Ｐの代用となる不動物が存在しない場合等に設けるとよい。 The overhanging material 115 can be used as a substitute for the steel pipe pile P when the connecting material 114 cannot be installed on the steel pipe pile P because the reinforcing bar cage S or the formwork F is installed in the construction target area E. It is recommended to provide it when there are no non-animals.
上記の構成を有する作業用建屋１０には、作業スペース１６に面する内側に、作業用足場１７と天井クレーン１８とが設けられている。 The work building 10 having the above configuration is provided with a work scaffold 17 and an overhead crane 18 inside facing the work space 16.
作業用足場１７としては、片持ち式のブラケット足場が採用され、図２で示すように、フレーム１２の走行方向に平行な側面であって、連結桁１５と支柱１３とにより囲まれる範囲の内側に複数段設置されている。 As the work scaffold 17, a cantilever type bracket scaffold is adopted, and as shown in FIG. 2, the side surface parallel to the traveling direction of the frame 12 is inside the range surrounded by the connecting girder 15 and the support column 13. It is installed in multiple stages.
また、天井クレーン１８としては、市場で取引されている何れの形式のものを採用してもよいが、本実施の形態ではいわゆるローヘッド型クレーンを採用し、図４で示すように、フレーム１２の天井部であって連結桁１５と連結梁１４とにより囲まれる範囲の内側に設置されている Further, as the overhead crane 18, any type of crane traded in the market may be adopted, but in the present embodiment, a so-called low-head type crane is adopted, and as shown in FIG. 4, the frame 12 It is installed inside the ceiling portion surrounded by the connecting girder 15 and the connecting beam 14.
具体的には、図４で示すように、フレーム１２の天井部であって内側に連結桁１５と平行な走行レール１８１が２本設置されるとともに、走行レール１８１に直交するガーダ１８２が２台の電動型サドル１８３を介して、走行レール１８１に沿って走行自在に設置されている。なお、電動型サドル１８３は、２本の走行レール１８１に１台ずつ設けられている。そして、図２で示すように、ガーダ１８２に走行トロリー１８４を介して揚重ホイスト１８５が懸垂されている。 Specifically, as shown in FIG. 4, two traveling rails 181 which are the ceiling portion of the frame 12 and parallel to the connecting girder 15 are installed, and two girders 182 orthogonal to the traveling rail 181 are installed. It is installed freely along the traveling rail 181 via the electric saddle 183 of the above. One electric saddle 183 is provided on each of the two traveling rails 181. Then, as shown in FIG. 2, a lifting hoist 185 is suspended from the girder 182 via a traveling trolley 184.
したがって、ガーダ１８２に沿って走行トロリー１８４を走行させることにより揚重ホイスト１８５は、フレーム１２の連結梁１４と平行な方向への移動が可能となる。また、走行レール１８１に沿って電動型サドル１８３を走行させてガーダ１８２を移動させることにより揚重ホイスト１８５は、フレーム１２の連結桁１５と平行な方向への移動が可能となる。 Therefore, by traveling the traveling trolley 184 along the girder 182, the lifting hoist 185 can move in the direction parallel to the connecting beam 14 of the frame 12. Further, by moving the girder 182 by traveling the electric saddle 183 along the traveling rail 181 the lifting hoist 185 can be moved in the direction parallel to the connecting girder 15 of the frame 12.
これにより、作業用建屋１０内の作業スペース１６において作業員は、作業用足場１７を利用した高所作業や、天井クレーン１８を採用した重量物の揚重作業を実施することが可能となる。なお、作業スペース１６となる作業用建屋１０の内部空間は、構築予定の壁体Ｗの横断面より十分大きく確保されていることはいうまでもない。そして、上記の構成を有する作業用建屋１０は、牽引機構３０に牽引されて走行ガイド２０のレール本体２１上を走行する。 As a result, in the work space 16 in the work building 10, the worker can perform aerial work using the work scaffold 17 and lifting work of a heavy object using the overhead crane 18. Needless to say, the internal space of the work building 10 serving as the work space 16 is sufficiently larger than the cross section of the wall body W to be constructed. Then, the work building 10 having the above configuration is towed by the towing mechanism 30 and travels on the rail main body 21 of the traveling guide 20.
≪牽引装置≫
牽引機構３０は、図５で示すように、ワイヤー３１がフレーム１２の支柱１３に接続されたウィンチ３２と、ウィンチ３２を鋼管杭Ｐに接続するクランプ３３とにより構成され、ワイヤー３１をウィンチ３２で巻き上げることにより作業用建屋１０を牽引し、レール本体２１上を移動させる。
≪Towing device≫
As shown in FIG. 5, the traction mechanism 30 is composed of a winch 32 in which the wire 31 is connected to the support column 13 of the frame 12 and a clamp 33 in which the winch 32 is connected to the steel pipe pile P, and the wire 31 is connected to the winch 32. By winding it up, the work building 10 is towed and moved on the rail body 21.
なお、クランプ３３の接続位置も、前述の連結材１１４と同様で鋼管杭Ｐに限定されるものではなく、施工現場内の不動物であればいずれに接続してもよい。また、作業用建屋１０は、必ずしも牽引機構３０を介してレール本体２１上で走行させる構成でなくてもよく、例えば、自走式の走行体１３１を採用してもよい。 The connection position of the clamp 33 is not limited to the steel pipe pile P as in the above-mentioned connecting member 114, and may be connected to any non-animal in the construction site. Further, the work building 10 does not necessarily have to be configured to travel on the rail body 21 via the traction mechanism 30, and for example, a self-propelled traveling body 131 may be adopted.
上記の構成を有する線状構造物構築作業システム１００によれば、作業用建屋１０に作業用足場１７だけでなく、天井クレーン１８が設けられていることから、作業用建屋１０の内側に設定された狭隘な作業スペース１６に、クレーンの揚重装置を別途配置する必要がないため、壁体Ｗの構築作業を実施する際の作業効率を向上することができる。 According to the linear structure construction work system 100 having the above configuration, since the work building 10 is provided with not only the work scaffolding 17 but also the overhead crane 18, it is set inside the work building 10. Since it is not necessary to separately arrange the crane lifting device in the narrow work space 16, it is possible to improve the work efficiency when carrying out the construction work of the wall body W.
また、作業用建屋１０の両側面に設けられた防護パネル１１１、遮蔽カーテン１１２とがプロテクタとして機能することから、施工現場が狭隘で壁体Ｗの構築予定領域が隣地境界に近接して位置する場合にも、施工現場周辺の住環境を確保しながら作業用建屋１０内の作業スペース１６で、壁体Ｗの構築作業を進捗させることが可能となる。 Further, since the protective panels 111 and the shielding curtain 112 provided on both side surfaces of the work building 10 function as protectors, the construction site is narrow and the planned construction area of the wall body W is located close to the boundary of the adjacent land. In this case as well, it is possible to proceed with the construction work of the wall body W in the work space 16 in the work building 10 while securing the living environment around the construction site.
特に、施工現場が道路に隣接する場合には、上記のとおりセメントが混じった排水やノロ等が道路の路面に漏出して交通阻害を引き起こすといった現象を抑制できるため、作業用建屋１０の側方で道路を供用させつつ、壁体Ｗの構築作業を進捗させることが可能となる。 In particular, when the construction site is adjacent to the road, it is possible to suppress the phenomenon that drainage and slag mixed with cement leak to the road surface and cause traffic obstruction as described above, so that the side of the work building 10 It is possible to proceed with the construction work of the wall body W while keeping the road in service.
また、施工現場で実施するクレーンを用いた揚重作業は作業用建屋１０内への資材搬入時のみであり、また、一般に実施される作業足場の組立及び解体作業も発生しないことから、道路を通行する一般車に吊荷や建設材料が接触する事故が生じにくく、安全性を向上することが可能となる。 In addition, the lifting work using a crane carried out at the construction site is only when the materials are brought into the work building 10, and the work scaffolding assembly and dismantling work that is generally carried out does not occur. Accidents in which suspended loads or construction materials come into contact with ordinary vehicles that pass through are less likely to occur, and safety can be improved.
≪≪鉄筋コンクリート造の壁体Ｗの構築方法≫≫
前述したように、壁体Ｗは鉄筋コンクリート造よりなり、その施工方法は、まず、一列に配置された複数の鋼管Ｐを基礎としてその上部に鉄筋かごＳを配置する。次に、この鉄筋かごＳを囲うようにして型枠Ｆを組み立てる。こののち、型枠Ｆ内にトレミー管Ｔを介してコンクリートＣを打設する。この３つの作業工程を、構築予定領域Ｅの長手方向に沿って繰り返し行う。
≪≪ How to build a reinforced concrete wall body W≫≫
As described above, the wall body W is made of reinforced concrete, and in the construction method thereof, first, a reinforcing bar cage S is arranged above a plurality of steel pipes P arranged in a row as a base. Next, the formwork F is assembled so as to surround the reinforcing bar cage S. After that, concrete C is placed in the formwork F via the tremie pipe T. These three work steps are repeated along the longitudinal direction of the planned construction area E.
そこで、本実施の形態では図１（ａ）（ｂ）で示すように、線状構造物構築作業システム１００に３台の作業用建屋１０１、１０２、１０３を設け、これら３台の作業用建屋１０で上記の３つの作業工程を分担して実施する。 Therefore, in the present embodiment, as shown in FIGS. 1A and 1B, three work buildings 101, 102, and 103 are provided in the linear structure construction work system 100, and these three work buildings are provided. In 10, the above three work processes are shared and carried out.
具体的には、走行方向の先頭に位置する作業用建屋１０１の作業スペース１６では、図２で示すように、鋼管Ｐの上部に鉄筋かごＳを配置する鉄筋組立作業を行う。後続の作業用建屋１０２の作業スペース１６では、図６で示すように、鉄筋かごＳの組み立てが終了した位置に型枠Ｆを組み立てる型枠組立作業を行う。そして、走行方向最後尾の作業用建屋１０３の作業スペース１６では、図７で示すように、型枠Ｆの組み立てが終了した位置の型枠Ｆ内にコンクリートを打設するコンクリート打設作業を行う。 Specifically, in the work space 16 of the work building 101 located at the head of the traveling direction, as shown in FIG. 2, a reinforcing bar assembly work is performed in which the reinforcing bar cage S is arranged above the steel pipe P. In the work space 16 of the subsequent work building 102, as shown in FIG. 6, the formwork assembly work of assembling the formwork F at the position where the assembly of the reinforcing bar cage S is completed is performed. Then, in the work space 16 of the work building 103 at the rearmost position in the traveling direction, as shown in FIG. 7, concrete placing work is performed in which concrete is placed in the formwork F at the position where the assembly of the formwork F is completed. ..
なお、３台の作業用建屋１０１、１０２、１０３はすべて、内方に作業用足場１７及び天井クレーン１８を有し、また、防護パネル１１１、遮蔽カーテン１１２、及び通気性面材１１３で被覆された構造に規格化している。これにより、３つの作業用建屋１０１、１０２、１０３のいずれを選択しても、上記３つの作業工程を実施することができるようになっている。 All three work buildings 101, 102, and 103 have a work scaffolding 17 and an overhead crane 18 inward, and are covered with a protective panel 111, a shielding curtain 112, and a breathable surface material 113. It is standardized to the structure. As a result, the above three work steps can be carried out regardless of which of the three work buildings 101, 102, and 103 is selected.
また、３台の作業用建屋１０１，１０２、１０３はそれぞれ、レール本体２１上で静止している状態では常時、連結材１１４を介して鋼管杭Ｐもしくはストッパー２２に連結し、レール本体２１からの逸走及び横転対策を施しておく。 Further, the three work buildings 101, 102, and 103 are always connected to the steel pipe pile P or the stopper 22 via the connecting member 114 in a state of being stationary on the rail main body 21, and are connected to the rail main body 21. Take measures against escape and rollover.
そして、まず、図１（ｂ）及び図２で示すように、先頭の作業用建屋１０１内の作業スペース１６で、作業用足場１７と鉄筋かごＳの揚重機能を有する天井クレーン１８とを用いて鋼管杭Ｐの上方に鉄筋かごＳを組み立てる。鉄筋組立工程が終了したところで牽引機構３０を用いて、先頭の作業用建屋１０１をレール本体２１上で走行させる。 Then, first, as shown in FIGS. 1B and 2, in the work space 16 in the first work building 101, a work scaffold 17 and an overhead crane 18 having a lifting function of the reinforcing bar cage S are used. Assemble the reinforcing bar cage S above the steel pipe pile P. When the reinforcing bar assembly process is completed, the traction mechanism 30 is used to run the leading work building 101 on the rail body 21.
次の鉄筋組立予定区域まで移動したところで、所定の位置に先頭の作業用建屋１０１を据え付け、再度鉄筋組立作業を実施する。この作業を壁体Ｗの構築予定位置の全てに鉄筋かごＳを設置するまで繰り返す。 After moving to the next planned rebar assembly area, the first work building 101 is installed at a predetermined position, and the rebar assembly work is performed again. This work is repeated until the reinforcing bar cages S are installed at all the planned construction positions of the wall body W.
先頭の作業用建屋１０１の移動作業と同時もしくは移動させたのちに、後続の作業用建屋１０２を牽引機構３０を用いてレール本体２１上で走行させ、鉄筋組立作業が終了した区域に到達させる。こののち、図１（ｂ）及び図６で示すように、後続の作業用建屋１０２を据え付けたうえで、作業スペース１６で作業用足場１７と型枠Ｆの揚重機能を有する天井クレーン１８とを用いて、鉄筋かごＳを挟んだ長手方向両側に型枠Ｆを組み立てる。 At the same time as or after moving the first work building 101, the subsequent work building 102 is moved on the rail body 21 by using the traction mechanism 30 to reach the area where the reinforcing bar assembly work is completed. After that, as shown in FIGS. 1 (b) and 6, after installing the subsequent work building 102, the work scaffold 17 and the overhead crane 18 having a lifting function of the formwork F are installed in the work space 16. Assemble the formwork F on both sides in the longitudinal direction sandwiching the reinforcing bar cage S.
型枠組立作業が終了したところで、牽引機構３０を用いて後続の作業用建屋１０２をレール本体２１上で走行させる。次の型枠組立予定区域まで移動したところで、所定の位置に後続の作業用建屋１０２を据え付け、作業スペース１６で再度型枠組立作業を実施する。この作業を壁体Ｗの構築予定位置の全てに型枠Ｆを設置するまで繰り返す。 When the formwork assembly work is completed, the traction mechanism 30 is used to run the subsequent work building 102 on the rail body 21. After moving to the next planned formwork assembly area, the subsequent work building 102 is installed at a predetermined position, and the formwork assembly work is performed again in the work space 16. This work is repeated until the formwork F is installed at all the planned construction positions of the wall body W.
後続の作業用建屋１０２の移動作業と同時もしくは移動させたのちに、最後尾の作業用建屋１０３を牽引機構３０を用いてレール本体２１上で走行させ、型枠組立作業が終了した区域に到達させる。こののち、図１（ｂ）及び図７で示すように、所定の位置に最後尾の作業用建屋１０３を据え付け、作業スペース１６で作業用足場１７とトレミー管Ｔの吊下げ機能を有する天井クレーン１８とを用いて、型枠Ｆ内にコンクリートＣを打設する。 At the same time as or after moving the work building 102 that follows, the rearmost work building 103 is run on the rail body 21 using the traction mechanism 30 to reach the area where the formwork assembly work has been completed. Let me. After that, as shown in FIGS. 1 (b) and 7, the rearmost work building 103 is installed at a predetermined position, and the work scaffold 17 and the tremie pipe T are suspended in the work space 16. Concrete C is placed in the formwork F using 18 and.
つまり、コンクリートＣを打設する際に用いるトレミー管Ｔは、図７で示すように、天井クレーン１８の揚重ホイスト１８５に支持させればよく、トレミー管ＴにコンクリートＣを供給する供給配管Ｂは、最後尾の作業用建屋１０３のフレーム１２もしくは作業用足場１７に沿わせて設置するとよい。これにより、狭隘な作業スペース１６であっても供給配管Ｂが邪魔にならず、効率よくコンクリートの打設作業を実施することができる。 That is, as shown in FIG. 7, the tremie pipe T used when placing the concrete C may be supported by the lifting hoist 185 of the overhead crane 18, and the supply pipe B for supplying the concrete C to the tremie pipe T may be supported. May be installed along the frame 12 of the last work building 103 or the work scaffold 17. As a result, even in a narrow work space 16, the supply pipe B does not get in the way, and the concrete placing work can be efficiently performed.
また、供給配管ＳにコンクリートＣを供給する圧送ポンプＳＰ及び圧送ポンプＳＰにコンクリートＣを供給するコンクリートミキサー車（図示せず）は、図１（ａ）で示すように、最後尾の作業用建屋１０３の進行方向後端側に配置しておく。これにより、施工現場内における圧送ポンプＳＰ及びコンクリートミキサー車（図示せず）の移動量を最小限に抑えて、施工対象領域内での安全性及び作業効率を確保することができる。 Further, as shown in FIG. 1A, the pressure feed pump SP that supplies the concrete C to the supply pipe S and the concrete mixer truck (not shown) that supplies the concrete C to the pressure feed pump SP are the last work buildings. It is arranged on the rear end side in the traveling direction of 103. As a result, the amount of movement of the pressure pump SP and the concrete mixer truck (not shown) in the construction site can be minimized, and safety and work efficiency in the construction target area can be ensured.
コンクリート打設作業が終了したところで、牽引機構３０を用いて最後尾の作業用建屋１０３をレール本体２１上で走行させる。次のコンクリート打設予定区域まで移動したところで、所定の位置に最後尾の作業用建屋１０３を据え付け、作業スペース１６で再度コンクリート打設作業を実施する。この作業を壁体Ｗの構築予定位置の全てにコンクリートＣを打設するまで繰り返す。 When the concrete placing work is completed, the traction mechanism 30 is used to run the rearmost work building 103 on the rail body 21. After moving to the next planned concrete placement area, the rearmost work building 103 is installed at a predetermined position, and the concrete placement work is performed again in the work space 16. This work is repeated until concrete C is placed at all the planned construction positions of the wall body W.
上記のとおり、３台の作業用建屋１０１、１０２、１０３ごとで３つの作業工程を分担するとともに、各々に分担された作業に必要な機能及び施工現場周辺の住環境保護に必要な機能を装備して、線状構造物構築作業システム１００の多機能集約化を図っている。そして、３台の作業用建屋１０１、１０２、１０３ごとで分担された作業を同時に並行して実施し、各々の作業が終了したところで、進行方向前方の所定位置に移動させたのち、再度分担された同じ作業を行う。これを構築予定領域Ｅに沿って繰り返し実施することにより、所望の長さを有する壁体Ｗを構築することができる。 As mentioned above, the three work buildings 101, 102, and 103 share three work processes, and each of them is equipped with the functions required for the assigned work and the functions necessary for protecting the living environment around the construction site. As a result, the linear structure construction work system 100 is being integrated into multiple functions. Then, the work assigned to each of the three work buildings 101, 102, and 103 is carried out in parallel at the same time, and when each work is completed, the work is moved to a predetermined position in front of the traveling direction and then shared again. Do the same work. By repeating this along the planned construction area E, the wall body W having a desired length can be constructed.
本発明の線状構造物構築作業システム１００及び線状構造物構築作業システム１００を用いた線状構造物Ｗの構築方法は、上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更が可能である。 The method for constructing the linear structure W using the linear structure construction work system 100 and the linear structure construction work system 100 of the present invention is not limited to the above embodiment and deviates from the gist of the present invention. Various changes can be made as long as they are not.
例えば、本実施の形態では、線状構造物構築作業システム１００で構築する線状構造物として、鉄筋コンクリート造の壁体Ｗを事例に挙げたが、必ずしもこれに限定されるものではなく、地上もしくは開削工法で構築する線状構造物であれば、いずれを採用することも可能である。 For example, in the present embodiment, the reinforced concrete wall body W is taken as an example as the linear structure to be constructed by the linear structure construction work system 100, but the present invention is not necessarily limited to this, and is not necessarily limited to this. Any linear structure constructed by the open-cut method can be adopted.
また、本実施の形態では、線状構造物構築作業システム１００に、鉄筋コンクリート造の壁体Ｗを構築するために実施する３つの作業工程と同数の、３台の作業用建屋１０１、１０２、１０３を採用したが、その数量は、これに限定されるものではない。例えば、作業用建屋１０の数量を増やして、複数の作業用建屋１０内で同一作業を実施してもよいし、作業用建屋の数量を減らして、１つの作業用建屋１０内で複数の作業を実施してもよい。 Further, in the present embodiment, three work buildings 101, 102, 103, which are the same number as the three work steps to be carried out for constructing the reinforced concrete wall body W in the linear structure construction work system 100. However, the quantity is not limited to this. For example, the number of work buildings 10 may be increased to carry out the same work in a plurality of work buildings 10, or the number of work buildings may be reduced to carry out a plurality of operations in one work building 10. May be carried out.
また、本実施の形態では、３台の作業用建屋１０１、１０２、１０３をすべて同一の構造に規格化したが、作業用建屋１０各々の作業スペース１６で実施する作業内容に応じて、作業用建屋の高さや長さもしくは形状等を適宜変更してもよいし、装備する設備を変更してもよい。 Further, in the present embodiment, the three work buildings 101, 102, and 103 are all standardized to have the same structure, but for work, depending on the work content to be performed in the work space 16 of each work building 10.
