Pre-reinforcement structure for construction of underground diaphragm wall in alluvial layer and construction method
The invention relates to a pre-reinforcement structure for construction of a diaphragm wall in an alluvial layer and a construction method, and belongs to the technical field of construction of underground diaphragm walls. The pre-reinforcement structure for the construction of the diaphragm wall in the alluvial layer comprises the underground diaphragm wall and guide walls oppositely arranged along the axis of the underground diaphragm wall; and a plurality of uniformly-arranged dense and closed row piles are arranged below the guide walls along the central axes of the guide walls, the dense and closed row piles and the guide walls are integrally poured, and the plurality of dense and closed row piles form a row pile wall. The construction method of the pre-reinforcement structure for the construction of the diaphragm wall in the alluvial layer comprises seven steps of stratum pre-judgment and reinforcement depth determination, technical preparation, construction preparation, drilling, drilling-spraying integrated pile forming, pile top chiseling away, pouring and backfilling and tamping. According to the pre-reinforcement structure for the construction of the diaphragm wall in the alluvial layer and the construction method, the safe, efficient and environment-friendly construction of the underground diaphragm wall can be ensured, accidents such as groove wall collapse, slurry leakage and piping in the construction of the underground diaphragm wall can be prevented and reduced, resource waste is reduced, and the construction cost is saved on.
连续墙在冲积层施工预加固结构及施工方法，属于地下连续墙施工技术领域，连续墙在冲积层施工预加固结构，包括地下连续墙和沿地下连续墙轴线相对设置的导墙，所述导墙下方沿导墙中心轴线设有若干个均匀设置的密集封闭式排桩，所述密集封闭式排桩与导墙一体浇筑，若干个所述密集封闭式排桩形成排桩墙。连续墙在冲积层施工预加固结构施工方法包括地层预判及加固深度确定、技术准备、施工准备、钻孔、钻喷一体成桩、桩顶凿除及浇筑及回填、夯实七个步骤。连续墙在冲积层施工预加固结构及施工方法能确保地下连续墙安全、高效、环保施工，可预防、减少地下连续墙施工中槽壁塌陷、浆液漏失、管涌等事故发生，减少资源浪费，节约施工成本。
