Recyclable drainage soil nail device and construction method
The invention discloses a recoverable drainage soil nailing device and a construction method, the drainage soil nailing device comprises a loop bar assembly and an ejector rod, the loop bar assembly comprises a cylindrical main sleeve, and one end of the main sleeve is connected with an end sleeve with a conical closed end part; a barb piece is arranged in the main sleeve in the axial direction, one end of the barb piece is rotatably installed on the main sleeve through a hinged shaft perpendicular to the axis of the main sleeve, and the main sleeve is further provided with a receding groove corresponding to the barb piece. The barb piece is provided with an abutting part protruding towards the middle of the main sleeve in the radial direction, and the minimum distance between the abutting part and the axis of the main sleeve is smaller than the radius of the ejector rod so that the ejector rod can penetrate into the main sleeve to enable the barb piece to rotate outwards out of the receding groove in the radial direction of the main sleeve. The multiple barb pieces are arranged in the length direction of the main sleeve at intervals, and the barb pieces are distributed in the circumferential direction of the main sleeve. The recoverable drainage soil nail device has the advantages of being ingenious in structural design, capable of being recycled after engineering is completed and the like.
本发明公开了一种可回收式排水土钉装置及施工方法，排水土钉装置包括套杆组件和顶杆，套杆组件包括整体呈圆筒状的主套管，主套管的一端连接有端部呈锥形封闭的端套管；主套管内具有沿轴向设置的倒刺件，倒刺件的一端通过垂直于主套管轴线的铰轴可转动地安装在主套管上，主套管上还具有与倒刺件对应设置的让位槽；倒刺件上具有沿径向朝向主套管的中部突出的顶触部，顶触部与主套管轴心线的最小距离小于顶杆的半径，使顶杆穿入主套管可将倒刺件沿主套管的径向向外转出让位槽；倒刺件沿主套管的长度方向间隔设置有多个，且倒刺件沿主套管的周向分布设置。本发明的可回收式排水土钉装置具有结构设计巧妙，能够在工程完成后后，进行回收再利用等优点。
