Prefabricated underground diaphragm wall, segmented connector structure and construction method
The invention belongs to the technical field of foundation pit engineering and particularly relates to a prefabricated underground diaphragm wall. A first embedded steel plate and a second embedded steel plate are laid at the two ends of a prefabricated underground diaphragm wall body correspondingly. Multiple bolt holes are reserved in one end of the prefabricated underground diagram wall body, multiple bolts are embedded in the other end of the prefabricated underground diagram wall body, and one ends of the bolts penetrate the second embedded steel plate. Multiple hand holes are formed in the side wall of the prefabricated underground diagram wall body, and the multiple bolt holes communicate with the multiple hand holes. The invention further provides a segmented connector structure ofthe prefabricated underground diagram wall and a construction method of the segmented connector structure of the prefabricated underground diagram wall. The construction method includes the steps that the above prefabricated underground diaphragm wall is adopted as the previous-constructed prefabricated underground diaphragm wall and the posterior-constructed prefabricated underground diaphragm wall; the bolts on the previous-constructed prefabricated underground diaphragm wall penetrate the corresponding bolt holes of the posterior-constructed prefabricated underground diaphragm wall and then stretch into the corresponding hand holes to be fixed through nuts. A prefabricated assembly manner is adopted, the construction quality can be ensured, the field construction processes are simplified, and the construction efficiency is improved.
本发明属于基坑工程技术领域，具体涉及一种预制地下连续墙，预制地下连续墙本体的两端分别铺设有第一预埋钢板和第二预埋钢板；预制地下连续墙本体的一端预留有多个螺栓孔，另一端预埋有多个螺栓，且各螺栓的一端贯穿第二预埋钢板；预制地下连续墙本体的侧壁上设有多个手孔，多个螺栓孔分别与多个手孔连通。本发明还提供一种预制地下连续墙分节接头结构及其施工方法，包括先行施工预制地下连续墙和后行施工预制地下连续墙，均采用上述的预制地下连续墙；先行施工预制地下连续墙上的螺栓贯穿后行施工预制地下连续墙上对应的螺栓孔后伸至对应的手孔内并通过螺母固定。本发明采用预制拼装形式，可以保证施工质量，简化现场施工工序，提高施工效率。
