Foundation pit top prefabricated water retaining wall structure and construction method thereof
The invention belongs to the technical field of foundation pit engineering and specifically relates to a foundation pit top prefabricated water retaining wall structure. The foundation pit top fabricated water retaining wall structure comprises a prefabricated water retaining wall and a crown beam. The top of the crown beam is provided with a reserved groove. The bottom of the prefabricated waterretaining wall is arranged in the reserved groove. Post-cast concrete is poured in the space between the prefabricated water retaining wall and the inner wall of the reserved groove. The prefabricatedwater retaining wall is connected with the top surface of the crown beam through fixing iron pieces. A construction method of the foundation pit top prefabricated water retaining wall structure comprises the steps of (1) prefabricating the prefabricated water retaining wall in a segmented mode in a factory and reserving bolt holes; (2) constructing an envelope structure and the crown beam, and reserving anchor bolt holes and the reserved groove; (3) hoisting the prefabricated water retaining wall, and mounting the bottom of the prefabricated water retaining wall in the reserved groove of thetop of the crown beam; (4) connecting the prefabricated water retaining wall with the crown beam through the fixing iron pieces; and (5) pouring the post-cast concrete into the space between the prefabricated water retaining wall and another prefabricated water retaining wall and the space between the prefabricated water retaining wall and the inner wall of the reserved groove. According to the foundation pit top prefabricated water retaining wall structure, the water retaining wall is prefabricated, is convenient to construct, economical and environment-friendly, and the assembly precision, the strength of connecting joints and the structure stability can be improved.
本发明属于基坑工程技术领域，具体涉及一种基坑顶装配式挡水墙结构，包括预制挡水墙和冠梁，冠梁的顶部设有预留槽，预制挡水墙的底部置于预留槽内，且预制挡水墙与预留槽的内壁之间浇筑有后浇混凝土；预制挡水墙通过固定铁件与冠梁的顶面连接；其施工方法：1）在工厂分段预制出预制挡水墙，并预留螺栓孔；2）施工围护结构与冠梁，并预留锚栓孔和预留槽；3）吊装预制挡水墙，将其底部安装于冠梁顶部的预留槽内；4）通过固定铁件将预制挡水墙和冠梁连接；5）在预制挡水墙与预制挡水墙之间以及预制挡水墙与预留槽的内壁之间浇筑后浇混凝土。本发明的挡水墙采用预制的形式，施工便捷、经济环保，且能提高装配精度、连接节点强度以及结构稳定性。
