Concrete upside-down hanging well suitable for saturated sand and construction method thereof
The invention discloses a concrete upside-down hanging well suitable for saturated sand. The concrete upside-down hanging well comprises a high-pressure jet grouting pile water stop tent, a concrete upside-down hanging well body, a pipeline compaction grouting composite foundation, an upside-down hanging well compaction grouting composite foundation, a current water supply and drainage pipeline and the like; the pipeline compaction grouting composite foundation is arranged at the position, located at a newly-built jacking pipe, of the outside of the concrete upside-down hanging well body, and the upside-down hanging well compaction grouting composite foundation is arranged at the bottom of the concrete upside-down hanging well body; and outer sleeves are arranged at the junctions between the current water supply and drainage pipeline as well as the newly-built jacking pipe and the concrete upside-down hanging well body separately, and a newly-built inspection well is arranged in the concrete upside-down hanging well body. The invention further discloses a construction method of the structure. According to the upside-down hanging well suitable for the saturated sand and the construction method thereof, the upside-down hanging well compaction grouting composite foundation is adopted for effectively sealing a bottom plate of the concrete upside-down hanging well body, underground water is isolated from the upside-down hanging well, and therefore smooth construction is guaranteed; and meanwhile, according to the construction method, the construction cost is reduced, the foundation bearing capacity is improved, and the integrity and strength of the whole structure are enhanced.
本发明公开了一种适用于饱和砂土中混凝土倒挂井，包括高压旋喷桩止水帐幕、混凝土倒挂井、管道压密注浆复合地基、倒挂井压密注浆复合地基、现状给排水管道等；混凝土倒挂井的外部在位于新建顶管的位置设置有管道压密注浆复合地基，混凝土倒挂井的底部设置有倒挂井压密注浆复合地基；现状给排水管道及新建顶管与混凝土倒挂井的交界处分别设置有外套管，混凝土倒挂井的内部设置有新建检查井。本发明还公开了上述结构的施工方法。本发明采用倒挂井压密注浆复合地基有效地进行混凝土倒挂井底板封底，将地下水与倒挂井隔离，从而保证施工的顺利进行；同时本发明的施工方法降低了工程造价，增加了地基承载力，增强了整体结构的整体性和强度。
