Construction method of ultra-deep underground diaphragm wall
The invention relates to a construction method of an ultra-deep underground diaphragm wall. Relates to the technical field of building construction. The method comprises the specific steps of groove section excavation, grooving quality inspection, sediment cleaning, reinforcement cage hoisting, grouting guide pipe arrangement, secondary bottom cleaning through a pump suction method, concrete pouring and the like. In the groove section excavation step, the second groove section and the first groove section are spaced by a certain distance, so that in the process of excavating the first groove section and the second groove section, the grab bucket type trenching machine is supported and limited by the wall on the periphery, the grab bucket of the grab bucket type trenching machine is balanced in stress, and the trenching quality of the first groove section and the second groove section is guaranteed; in the process of excavating the third groove section, the grab bucket of the grab bucket type trenching machine can sleeve the guide partition walls from the two sides to conduct excavation, the grab bucket of the grab bucket type trenching machine can bear balanced force through supporting and limiting of the guide partition walls, and therefore the trenching quality of the third groove section is guaranteed, the construction efficiency is improved, and the construction quality of the underground diaphragm wall is guaranteed.
本发明涉及公开了一种超深地下连续墙施工方法。涉及建筑施工技术领域。本方法具体槽段开挖、成槽质量检验、沉渣清理、吊装钢筋笼、设置注浆导管、泵吸法二次清底、以及浇灌混凝土等步骤。本发明的槽段开挖步骤中，第二槽段与第一槽段间隔一定距离，因此在挖掘第一槽段和第二槽段的过程中，墙壁在四周对抓斗式成槽机进行支撑限位，使抓斗式成槽机的抓斗吃力均衡，从而保证第一槽段和第二槽段的成槽质量；在挖掘第三槽段的过程中，抓斗式成槽机的抓斗可以从两侧套住导向隔墙进行挖掘，通过导向隔墙的支撑限位，同样能使抓斗式成槽机的抓斗吃力均衡，从而保证第三槽段的成槽质量，进而既提高施工效率，又保障地下连续墙的施工质量。
