Prefabricated underground diaphragm wall inter-width segmental connecting piece and anchoring construction method
The connecting piece comprises an omega-shaped inter-amplitude connecting piece body and a T-shaped inter-amplitude connecting piece body, the omega-shaped inter-amplitude connecting piece body is arranged in a groove of the Nth prefabricated underground diaphragm wall, an opening of the omega-shaped inter-amplitude connecting piece body faces the (N + 1) th prefabricated underground diaphragm wall, and the T-shaped inter-amplitude connecting piece body is arranged in a groove of the T-shaped inter-amplitude connecting piece body. The T-shaped inter-amplitude connecting piece is arranged in a tenon of the (N + 1) th prefabricated underground diaphragm wall, and the omega-shaped inter-amplitude connecting piece and the T-shaped inter-amplitude connecting piece are connected in an inter-amplitude mode; the construction method comprises the following steps that the inter-width connecting pieces are machined; processing a structure for anchoring the inter-width connecting piece; segmented slotting is machined; correcting and accepting; transferring to a prefabricated part processing factory; carrying out segment splicing and welding on the inter-width connecting pieces; anchor bolts are installed; hoisting and fixing the complete inter-width connecting piece; a prefabricated underground diaphragm wall is manufactured; the adjacent prefabricated underground diaphragm walls are assembled in a guiding mode; and finishing construction. High-precision, high-efficiency and high-quality assembly of the prefabricated underground diaphragm wall is achieved.
本发明公开了一种预制地连墙幅间可分节连接件及锚固的施工方法，其连接件包括Ω形幅间连接件、T形幅间连接件，Ω形幅间连接件设置在第N幅预制地下连续墙的凹槽中，且开口朝向第N+1幅预制地下连续墙，T形幅间连接件设置在第N+1幅预制地下连续墙的凸榫中，Ω形幅间连接件、T形幅间连接件进行幅间相连；其施工方法，包括以下步骤：加工幅间连接件；加工用于幅间连接件锚固的结构；加工分节开槽；矫正和验收；转运至预制构件加工厂；进行幅间连接件的节段拼接和焊接；安装地脚锚栓；吊放并固定完整的幅间连接件；制作预制地下连续墙；进行相邻幅预制地下连续墙的导向拼装；完成施工。本发明实现了预制地下连续墙的高精度、高效率、高质量拼装。
