Temporary steel pipe pile pulling-out device based on thixotropic slurry resistance reduction and construction method of temporary steel pipe pile pulling-out device
The invention belongs to the technical field of steel pipe pile construction, and particularly relates to a temporary steel pipe pile pulling-out device based on thixotropic slurry resistance reduction and a construction method thereof.The temporary steel pipe pile pulling-out device comprises a steel pipe pile, a grouting pipeline, thixotropic slurry, grouting equipment, hoisting equipment and a vibratory hammer; the grouting pipelines are distributed on the inner periphery of the steel pipe pile and fixedly connected with the inner wall of the steel pipe pile, the grouting pipelines are communicated with the slurry outlet holes and communicated with surrounding soil through the slurry outlet holes, and the thixotropic slurry is injected into the space between the steel pipe pile and the surrounding soil through the grouting pipelines. And a circle of thixotropic slurry sleeve is formed between the steel pipe pile and the surrounding soil body. The method has the beneficial effects that the thixotropic slurry is adopted to reduce the side friction resistance between the steel pipe pile and the soil body, and the counter force required to be provided for pulling out the steel pipe pile is greatly reduced, so that small mechanical equipment can be adopted for pulling out the steel pipe pile, and the construction is convenient and rapid.
本发明属于钢管桩施工技术领域，尤其涉及一种基于触变泥浆减阻的临时钢管桩拔除装置及其施工方法，包括钢管桩、注浆管道、触变泥浆、注浆设备、起重设备以及振动锤，所述钢管桩下部埋入土体部分沿环向、竖向均匀设置有出浆孔，所述注浆管道分布在所述钢管桩内周并与所述钢管桩内壁固定连接，所述注浆管道与所述出浆孔连通，并通过所述出浆孔与周围土体连通，所述触变泥浆通过所述注浆管道注入所述钢管桩与周围土体间，在所述钢管桩与周围土体间形成一圈触变泥浆套。本发明的有益效果是：采用触变泥浆减小钢管桩与土体间的侧摩阻力，极大的降低了拔除钢管桩所需提供的反力，从而可以采用小型机械设备进行钢管桩拔除，施工方便快捷。
