Equipment for reinforcing silty-fine sand foundation of passenger transport line and reinforcing method
The invention discloses equipment for reinforcing a silty-fine sand foundation of a passenger transport line, and belongs to the technical field of foundation reinforcement. The equipment comprises atubular pile and a pile tip, the pile tip is movably connected with the outer wall of the bottom of the tubular pile through a buckle, holes are uniformly formed in the bottom of the outer wall of thetubular pile, and a rotating device sleeves the tubular pile. The rotating device comprises an inner pipe inserted into an inner cavity of the tubular pile, a connecting block sleeves the top end ofthe outer wall of the inner pipe, an outer pipe sleeves the outer wall of the connecting block, and open holes are evenly formed in the bottoms of the outer pipe and the outer wall of the inner pipe.The inner pipe and the outer pipe are rotated by rotating the rotating device, so that the open holes and the holes are staggered. The connection between the silty-fine sand pile inside the tubular pile and the silty-fine sand of the foundation outside the tubular pile is broken, and the connection between the silty-fine sand pile, the silty-fine sand of the foundation outside the tubular pile andthe silty-fine sand inside the holes is further broken, so that the silty-fine sand pile or the silty-fine sand foundation compacted outside is not pulled in the pipe pulling process, and the compacted reinforced foundation is prevented from being damaged.
本发明公开了地基加固技术领域的一种加固客运专线粉细砂地基的设备，包括管桩与桩尖，所述桩尖通过卡扣与管桩底部外壁活动连接，所述管桩外壁底部均匀开设有孔洞，所述管桩上套接有转动装置，所述转动装置包括插在管桩内腔中的内管，所述内管外壁顶端套接有连接块，所述连接块外壁套接有外管，所述外管与内管外壁底部均匀开设有开孔，装置中通过旋转转动装置，使内管与外管转动，使开孔与孔洞错位，断开管桩内部粉细砂桩与管桩外界地基粉细砂的连接，也断开粉细砂桩、外界地基粉细砂与孔洞内部粉细砂的连接，从而使拔管的过程中，不会对粉细砂桩或外界压实的粉细砂地基造成拉扯，避免对压实加固的地基造成破坏。
