Fabricated underground continuous wall foundation groove gap filling method
The invention discloses an assembly type underground continuous wall foundation groove gap filling method. The method comprises the steps that a guide wall foundation groove is excavated; pre-burying a grouting pipe; the foundation trench gap on the side of the first underground diaphragm wall is backfilled; the next underground diaphragm wall is assembled; the foundation trench gap on the side of the next underground diaphragm wall is backfilled; the above steps are repeated until backfilling of the foundation trench gap on the side of the last but one underground diaphragm wall is completed; and the last underground diaphragm wall is hoisted, then placed in the guide wall foundation trench and spliced with the previous underground diaphragm wall, the foundation trench gap which is not backfilled is backfilled with gravel until the foundation trench gap is filled with the gravel, and grouting is conducted on the foundation trench gap through the pre-buried grouting pipe. According to the construction method, a method of periodically and circularly backfilling the foundation trench gaps is adopted, the gravels are backfilled every time the assembly of one underground diaphragm wall is completed, support can be provided for the assembled underground diaphragm wall and the trench wall in time, the wall piece assembly sag is ensured, the compact filling of the gravels is ensured, and the assembly construction requirements of the ultra-deep underground diaphragm wall can be met.
本申请公开一种装配式地下连续墙基槽缝隙填充方法，包括导墙基槽开挖；预埋注浆管；第一幅地下连续墙侧的基槽缝隙回填：下一幅地下连续墙的拼装：下一幅地下连续墙侧的基槽缝隙回填；重复上述步骤至完成倒数第二幅地下连续墙侧的基槽缝隙回填；将最后一幅地下连续墙起吊后放置在导墙基槽内并与前一幅地下连续墙进行拼装，向未回填的基槽缝隙内回填砂石，直到基槽缝隙内填满砂石，通过预埋注浆管对基槽缝隙进行注浆。本申请采用阶段性循环回填基槽缝隙的方法，每完成一幅地下连续墙的拼装就回填砂石，能及时为已拼装地下连续墙和槽壁提供支护，确保墙片拼装垂度，确保砂石填充密实，能满足超深地下连续墙装配施工要求。
