Supporting structure and method for surrounding deep foundation pit of building group under silt geology
The invention relates to a building group surrounding deep foundation pit supporting structure and method under the silt geology, and belongs to the technical field of tubular piles, the building group surrounding deep foundation pit supporting structure comprises a first tubular pile and a second tubular pile, the first tubular pile and the second tubular pile are fixed in an end-to-end welding mode, a sleeve is fixed to the outer side of the welding position of the first tubular pile and the second tubular pile, and a plurality of sealing blocks are slidably connected into the sleeve; when the multiple sealing blocks get close to each other, the welding position of the first pipe pile and the second pipe pile can be attached and held tightly, a driving assembly used for driving the sealing blocks to move is arranged in the sleeve, a supporting frame and an annular frame are fixed to the outer wall of the sleeve, and a main arch frame and an auxiliary arch frame are fixed to the annular frame. The method has the effects that the contact between the pipe pile welding seam and soil can be reduced, and the service life of the pipe pile is prolonged.
本申请涉及一种针对淤泥地质下群楼环绕深基坑支护结构及方法，属于管桩的技术领域，其包括第一管桩和第二管桩，第一管桩和第二管桩首尾焊接固定，第一管桩和第二管桩焊接处外侧固定有套筒，套筒内部滑动连接有多个密封块，多个密封块相互靠近的时候可以将第一管桩和第二管桩焊接处贴合抱紧，套筒内部设置有用于驱动密封块运动的驱动组件，套筒外壁上固定有支撑架和环形架，环形架上固定有主拱形架和副拱形架，本申请具有可以减少管桩焊接缝与泥土接触，增加管桩使用寿命的效果。
