Pile foundation steel retaining wall sleeve device capable of being rotationally lowered and construction method thereof
The invention discloses a pile foundation steel retaining wall sleeve device capable of rotatably lowering and a construction method thereof.The pile foundation steel retaining wall sleeve device comprises a power mechanism, a sleeve body arranged on the power mechanism and used for driving the sleeve body to rotate, and a reinforcing mechanism arranged on the sleeve body and used for reinforcing the rigidity of the sleeve body; the sleeve body is arranged in the sleeve body to prevent the sleeve body from buckling under the action of torque, and the multiple tool bits are fixed to the bottom of the sleeve body. According to the pile foundation steel retaining wall sleeve device capable of being rotationally lowered and the construction method thereof, obstacles are broken, and the rigidity of the sleeve body is improved through the stiffening ribs; the problems that in the prior art, the sleeve cannot be lowered when encountering an obstacle in a self-weight lowering mode and is prone to being affected by local buckling are solved, the problem that the sleeve cannot be lowered when encountering a hard obstacle in a pile press-in pressure lowering mode is solved, the requirement for the strength of the sleeve is high when the sleeve is driven into the ground through impact piling, and the strength of an existing sleeve is insufficient are solved.
本发明公开了一种可旋转下放的桩基钢护壁套筒装置及其施工方法，包括动力机构，套筒本体，该套筒本体设置在动力机构上，所述动力机构带动套筒本体旋转，加强机构，该加强机构设置在套筒本体上，所述加强机构用于增强套筒本体刚性，防止套筒本体在扭矩作用下发生屈曲，以及多个刀头，多个所述刀头固定在所述套筒本体底部；该可旋转下放的桩基钢护壁套筒装置及其施工方法，实现对障碍物破碎，加劲肋提高套筒本体刚性，解决了现有技术中自重下放的方式遇到障碍物无法下放、容易受到局部屈曲影响的问题、压桩机施加压力下放方式遇到硬质障碍物也无法下放的问题及冲击打桩将套筒打入地下对套筒的强度要求较高，现有套筒强度不够的问题。
