Wall-mounted wing wall combined with cast-in-place pile foundation pit supporting and construction method thereof
The invention discloses a wall-mounted wing wall combined with cast-in-place pile foundation pit supporting and a construction method thereof. The wall-mounted wing wall comprises cast-in-place piles, a pile top platform and wall plates; the wall plates are located in front of the exposed faces of the cast-in-place piles, and the rear walls of the wall plates are connected with the exposed faces of the cast-in-place piles in a pouring manner to serve as main soil retaining and supporting structures of the wing wall; and the pile top platform is fixed to the tops of the cast-in-place piles, and the pile top platform and the lower wall plates are combined to serve as a wing wall upper supporting structure. The construction method of the wall-mounted wing wall comprises the steps that firstly, basic plane scabbling and cleaning are conducted on original cast-in-place piles and pile top beams, then net hanging reinforcing steel bar drilling is conducted, then rear reinforcing steel bars are buried, a double-layer reinforcing steel bar net is arranged, a formwork is erected, and finally layered concrete pouring is conducted, so that the cast-in-place piles, the pile top platform and the wall plates form the integrated wall-mounted wing wall, and formwork removal and forming are conducted. The wall-mounted wing wall can adapt to the limitation of various complex terrains and site conditions, the integrity of a supporting structure and a soil retaining structure is improved, the construction period is shortened, and the construction cost is reduced.
本发明公开了一种与钻孔灌注桩基坑支护相结合的挂壁式翼墙及其施工方法，该挂壁式翼墙包括灌注桩、桩顶平台和壁板；所述壁板位于灌注桩外露面前方，壁板后壁与灌注桩外露面浇筑连接作为该翼墙主要挡土及支护结构；所述桩顶平台固定于灌注桩顶部，桩顶平台与下部壁板结合作为翼墙上部支撑结构；其施工方法为先对原有的灌注桩和桩顶冠梁进行基础面凿毛、清理，再进行挂网钢筋钻孔，然后埋设后置钢筋、布设双层钢筋网、架立模板，最后进行分层浇筑混凝土，使灌注桩、桩顶平台和壁板形成一体式的挂壁式翼墙，拆模成型。本发明能适应各种复杂地形及场地条件的限制，提升了支护结构与挡土结构的整体性，缩短了工期，降低了施工成本。
