Foundation pit supporting structure close to existing building side and construction technology
The foundation pit supporting structure comprises row piles arranged on the side close to the existing building, a top beam is arranged at the tops of the row piles, and a first supporting stirrup is arranged on the side, facing a foundation pit, of the top beam; in the first supporting state, back pressure soil bodies are arranged on the sides, facing the foundation pit, of the row piles, a structural bottom plate is arranged in a non-back pressure soil body area at the bottom of the foundation pit, and second supporting stirrups are arranged on the structural bottom plate; in the second supporting state, a first inclined strut is connected between the first supporting stirrup and the second supporting stirrup; in the third supporting state, a structural bottom plate is arranged in the whole area of the bottom of the foundation pit, a structural side wall is arranged on the side, facing the foundation pit, of the row piles, a third supporting stirrup is arranged on the position, close to the middle, of the structural side wall, and a fourth supporting stirrup is arranged on the position, close to the structural side wall, of the structural bottom plate. And a second inclined strut is connected between the third supporting stirrup and the fourth supporting stirrup. The problem that an existing support is small in working space is solved.
本发明公开了一种临近既有构筑物侧的基坑支护结构及施工工艺,包括设于临近既有构筑物侧的排桩,排桩的顶部设有冠梁,冠梁朝向基坑的一侧设有第一支护马镫;在第一支护状态时,排桩朝向基坑的一侧设有反压土体,基坑底部非反压土体区域设有结构底板,结构底板上设置有第二支护马镫;在第二支护状态时,第一支护马镫与第二支护马镫之间连接有第一斜撑;在第三支护状态时,基坑底部整个区域设有结构底板,排桩朝向基坑的一侧设有结构侧墙,结构侧墙上靠近中部位置设有第三支护马镫,结构底板上设靠近结构侧墙的位置设有第四支护马镫,第三支护马镫与第四支护马镫之间连接有第二斜撑。本发明的目的在于解决现有支护存在工作空间小的问题。
