Ultra-deep underground diaphragm wall and construction method
The invention relates to an ultra-deep underground diaphragm wall and a construction method, the problem that a three-shaft mixing pile is high in strength and hard on one side and soft on the other side and is difficult to correct is solved by using a cylindrical rotary drilling bit with side cutting teeth, so that the perpendicularity of a groove section meets the design requirement, and the subsequent construction quality is prevented from being influenced; in the construction process, the guide wall steel formwork can be accurately adjusted and fixed through the screw rods and the adjusting nuts on the steel formwork; the combined water stop component is used for conducting waterproof construction on the underground diaphragm wall at the construction joint, on the basis that the bearing performance of the underground diaphragm wall structure is guaranteed, the problem that the waterproof performance of the underground diaphragm wall at the construction joint is difficult to guarantee is solved, and the overall construction quality of the underground diaphragm wall is improved.
本发明涉及一种超深地下连续墙及施工方法，通过使用带有侧面截齿的筒式旋挖钻头解决三轴搅拌桩强度高且一边硬、一边软导致的难以修正问题，使得槽段垂直度满足设计要求，避免影响后续施工质量；施工过程中通过钢模板上螺杆及调节螺母，可以对导墙钢模板进行精准的调节固定；用组合式止水构件对施工接缝处地连墙进行防水施工，在保证地连墙结构承载性能的基础上，解决了地连墙施工接缝处防水性难保证的问题，提升了地下连续墙的整体施工质量。
