Squeeze-in underground diaphragm wall gapless steering device

Abstract

The invention relates to a squeezing type underground continuous wall gapless steering device, and belongs to the technical field of underground space development static force extrusion. The problem that in the construction process of an existing static pressure underground continuous wall, steering is incoherent, water seepage happens, and the wall forming quality is affected is solved. The squeezing type underground continuous wall gapless steering device comprises a shell, a vibration cooling device and a rotating device, the vibration cooling device is located in the shell, and the rotating device is arranged at the upper end of the shell. The squeezing type underground continuous wall gapless steering device is applied to the axis angle change of a squeezing type underground continuous wall and steering with the angle larger than or smaller than 90 degrees.

Description

technical field [0001] The invention relates to a squeeze-in type underground continuous wall gapless steering device, which belongs to the technical field of static squeeze-in for underground space development. Background technique [0002] At present, the walking systems of all hydraulic static pile drivers (hereinafter referred to as static pile drivers) at home and abroad are all walking systems. When turning or moving in a straight line during the pile pressing process, the piles are cut off from the surface or directly pressed against the top of the piles. The construction technology of the squeeze-in underground diaphragm wall (hereinafter referred to as the squeeze-in floor wall) requires at least one wall-forming device that cannot be pulled out of the ground before the construction of the squeeze-in floor wall is completed, otherwise, it will be damaged due to the unit wall section.

Problems solved by technology

[0002] At present, the walking systems of all hydraulic static pile drivers (hereinafter referred to as static pile drivers) at home and abroad are all walking systems. When turning or moving in a straight line during the pile pressing process, the piles are cut off from the surface or directly pressed against the top of the piles. The construction technology of the squeeze-in underground diaphragm wall (hereinafter referred to as the squeeze-in floor wall) requires at least one wall-forming device that cannot be pulled out of the ground before the construction of the squeeze-in floor wall is completed, otherwise, it will be damaged due to the unit wall section. The incoherent mechanical connection between them will cause water seepage, which will affect the quality of the wall; moreover, the wall-forming device is expensive and can be used repeatedly.

The existing method is to implement the inner and outer multi-layered overlapping corner walls according to the corresponding angles at the corners of the ground wall to seal the interface to achieve the purpose of waterproofing and anti-seepage; practice has proved that the sealing effect of the overlapping sealing method at the corners of the extruded ground wall is not good. Especially in the saturated water soft soil layer or complex soil layer, the waterproof effect of the overlapping corner wall basically fails to meet the technical requirements for waterproof and anti-seepage
