TOWING TYPE UNDERPASS CONSTRUCTION METHOD
To provide a towing type underpass construction method capable of obtaining a stable support reaction force when towing even if a box structure is heavy.SOLUTION: The present invention includes a box-shaped roof forming step of forming a box-shaped roof 22 on the ground immediately below an expressway 50, and a towing step of towing a box structure 20 to an arrival base 52 side while replacing it with the box-shaped roof 22, and installing it on the ground below the expressway 50. In the towing step, at the arrival base 52, a tie beam 13 is erected between an opposing surface portion 11b of a support wall 11 in the towing direction X and a face wall portion 53a of an embankment ground below the expressway 50, and by using the erected tie beam 13, the support reaction force when the box structure 20 is towed by a towing steel wire 12 is borne not only by the support wall 11 but also by the face wall portion 53a of the embankment ground.SELECTED DRAWING: Figure 2
【課題】函体構造物の重量が重いものであっても、けん引する際の支持反力を、安定した状態で得ることのできるけん引式アンダーパス工法を提供する。【解決手段】高速道路５０の直下部分の地盤に箱形ルーフ２２を形成する箱形ルーフ形成工程と、函体構造物２０を、箱形ルーフ２２と置き換えるようにしつつ、到達基地５２側にけん引して、高速道路５０の下方の地盤に設置するけん引工程とを含んでいる。けん引工程では、到達基地５２において、支持壁体１１のけん引方向Ｘの対向面部１１ｂと、高速道路５０の下方の盛土地盤の鏡壁面部５３ａとの間につなぎ梁１３を架設しておき、架設した該つなぎ梁１３を介することで、けん引用鋼線１２によって函体構造物２０をけん引する際の支持反力を、支持壁体１１のみならず盛土地盤の鏡壁面部５３ａにも負担させる。【選択図】図２
