Sludge geology deep foundation pit supporting system and construction method thereof
The invention relates to a silt geology deep foundation pit supporting system and a construction method thereof. The silt geology deep foundation pit supporting system comprises an enclosure structure arranged around a design area of a foundation pit; the multiple rows of first pile foundations are driven in the design area of the foundation pit at intervals, the bottom elevation of the first pile foundations is lower than the bottom elevation of the foundation pit, and the foundation pit is formed by excavating in the enclosure structure; the supporting assemblies are connected between the two opposite sides of the enclosure structure in a jacking and supporting mode at intervals, and the supporting assemblies are transversely arranged and located on the top of the foundation pit; and the concrete cushion layer is arranged on the bottom surface of the foundation pit in a covering manner. The supporting system supports and reinforces the bottom and the top of the foundation pit so as to resist lateral pressure from the periphery of the foundation pit, and the foundation pit does not need to be excavated through dewatering, so that the risk that surrounding buildings settle due to dewatering of the foundation pit can be avoided.
本发明涉及一种淤泥地质深基坑支护系统及其施工方法，包括：沿基坑的设计区域的周围设置的围护结构；间隔地打设于所述基坑的设计区域内的若干排第一桩基，所述第一桩基的底标高低于所述基坑的底标高，通过于所述围护结构内开挖形成所述基坑；间隔地顶撑连接于所述围护结构的相对两侧之间的若干个支撑组件，呈横向设置且位于所述基坑的顶部；覆盖地设于所述基坑底面之上的砼垫层。本发明的支护系统形成对基坑的底部和顶部的支撑和加固作用，以抵御来自基坑周围的侧压力，本发明由于本申请无需采用降水开挖基坑，进而能够避免因基坑降水导致周边建筑物沉降的风险。
