Embodiment Construction

[0043] The present invention will be described below with reference to the accompanying drawings:

[0044]1. Preparation before the excavation of the groove: the exploration wall corresponds to the physical and mechanical characteristics of the rock soil in the groove, provides a basis for the selection of the wall of the excavator. When the opening of the excavation layer is mainly the viscous soil layer, the wall should be embedded with the rail beam. The wall excavation machine should be used to walk on the track beam in a housing, and the mechanical weight is passed from the wall to the adjacent support pile 6. Lighter equipment; when the excavation layer is mainly sanded or rock, it is possible to consider using crawler excavators, and the self-weight of the excavator is borne by unshaated rock. After the excavator is selected, the working space required for its desired work is determined, and the load required for the wall foot supporting the pile 6 can be determined by weig...

Abstract

The invention belongs to the technical field of civil construction underground engineering, and provides a sinking wall construction method, which enables the wall to sink in a controlled manner, and is relatively economical and reasonable. Excavate the rock and soil layer by layer, use the jack on the supporting pile to support the wall at the bottom of the excavated groove so that the bottom of the wall is suspended, use the jack to lift the supporting pile to cooperate with the excavation; after layered excavation, use the jack to press the supporting pile Until its settlement is stable; the wall and the retaining structure are entrained with roller elastic support rods, which transmit the balanced rock-soil pressure and control the sinking frictional resistance; the wall sinks under the control of the jack for a section, and the ground is raised for a section. When this construction method is used for foundation pit support, after connecting the basement exterior wall and the steel support wall on the ground, they sink in place under control at the same time, and then carry out large-scale excavation, which can prevent accidents caused by insufficient support. The support system has strong adaptability to architectural schemes and geology. This construction method can also be used in the construction of slope retaining walls and underground anti-seepage walls.

Description

Technical field [0001] The present invention belongs to the field of civil engineering underground engineering, involving a construction method for underground walls. Background technique [0002] First, on the ground, the wall of the wall corresponding to the groove body is pulled out, so that the wall will sink from the ground to the ground, it can be called a wall method. Traditional Shenjing Fair is all excavated of the generous body around the well. There are many patents to provide a method and apparatus for sinking wall. China Patent (CN1120104A) discloses a ground wall construction method, displaced with a water gun to form mud water, and the jet pump is removed from the mud water, and the wall is separated by the blade soil, and the weight is separated by the film; The aqueous ring surrounding the wall is reduced and prevents the collapse of the earth. China Patent (CN101338567B) discloses a construction method for the construction of semi-inverse processes in accordance...
