Construction method for underground diaphragm wall system under weak geological condition in reclamation area
The invention discloses a construction method for an underground diaphragm wall system under weak geological conditions in a reclamation area. The construction method comprises the following construction steps: surveying and setting out; soft foundation treatment: carrying out soft foundation treatment according to the measured and paid-out underground diaphragm wall line position; grooving and reinforcing, wherein grooving and reinforcing treatment is conducted on the two sides of the underground diaphragm wall line position; grooving the underground diaphragm wall; manufacturing an underground diaphragm wall reinforcement cage; hoisting an underground diaphragm wall reinforcement cage; pouring underground diaphragm wall concrete; and backfilling an empty wall section. In the S2, grating type cement mixing pile soft foundation treatment is carried out on a soft geological layer within the range of 12 m on one side of the underground diaphragm wall, and grating type single-pipe jet grouting pile soft foundation treatment is carried out on a rock-filled layer geological layer containing construction waste and disordered miscellaneous filling within the range of 12 m on one side of the underground diaphragm wall. The construction method for the underground diaphragm wall system under the weak geological condition of the reclamation area has the advantage of being high in supporting strength, and during application, the construction difficulty can be lowered, the construction period can be shortened, and the engineering benefit can be improved.
本发明公开了一种用于填海区软弱地质条件下地下连续墙系统的施工方法，包括以下的施工步骤：测量放线；软基处理，根据测量及放线好的地下连续墙线位进行软基处理；成槽加固，对地下连续墙线位的两侧进行成槽加固处理；地下连续墙成槽；制作地下连续墙钢筋笼；吊装地下连续墙钢筋笼；浇筑地下连续墙混凝土；空墙段回填；在步骤S2中，地下连续墙一侧12m范围内的软弱地质层进行格栅式水泥搅拌桩软基处理，地下连续墙一侧12m范围内的含有建筑垃圾及无序杂填的填石层地质层进行格栅式单管旋喷桩软基处理。该种用于填海区软弱地质条件下地下连续墙系统的施工方法具有支护强度大的特点，在应用时可降低施工难度、节省工期、提升工程效益。
