Open cut tunnel assembly integral structure and construction method thereof
The invention discloses an open-cut tunnel assembly integral structure and a construction method thereof. The open-cut tunnel assembly integral structure comprises a bottom plate, side walls and a top plate. The bottom plate comprises a bottom plate main body and a bottom plate side wall joint; each side wall and the top plate comprise a precast slab facing the inner side of the tunnel and a cast-in-place layer facing the outer side of the tunnel; the reinforcing steel bars of each cast-in-place layer and the reinforcing steel bars of the corresponding prefabricated slab are of an integral structure, and manufacturing is completed while the corresponding prefabricated slab is prefabricated; the reinforcing steel bars of the prefabricated plate of each side wall extend into the corresponding joints between the side walls of the bottom plate and the top plate to be anchored; the steel bars of the cast-in-place layer of each side wall are in lap joint with the steel bars of the bottom plate body and the steel bars of the cast-in-place layer of the top plate. During construction, the bottom plate body is firstly poured, then the prefabricated side walls and the prefabricated top plate are hoisted, and after anchoring and lap joint of the steel bars are completed, all cast-in-place layers and joints between the side walls of the bottom plate are secondarily poured. The problems that in the prior art, the construction mechanization degree is low, construction procedures are complicated, and the construction precision requirement is high are solved.
本发明公开了明挖隧道装配整体式结构及其施工方法，包括底板、侧墙和顶板；底板包括底板主体，以及底板侧墙间接头；每一侧墙和顶板均包括朝向隧道内侧的预制板，以及朝向隧道外侧的现浇层；每一现浇层的钢筋均与相应的预制板的钢筋为一整体结构，在相应的预制板预制时同时完成制作；每一侧墙的预制板的钢筋均伸入相应的底板侧墙间接头，以及顶板进行锚固；每一侧墙的现浇层的钢筋均与底板主体的钢筋，以及顶板的现浇层的钢筋搭接。施工时，先浇筑底板主体，然后吊装预制完成侧墙和顶板，完成钢筋的锚固和搭接后，二次浇筑所有的现浇层和底板侧墙间接头。本发明解决了现有技术施工机械化程度低、施工工序繁复、施工精度要求高等问题。
