Anti-loosening pressure type prestress self-checking anti-floating anchor rod and construction method thereof
The invention discloses an anti-loosening pressure type prestress self-checking anti-floating anchor rod and a construction method thereof, and belongs to the technical field of foundation construction, and the anti-floating anchor rod comprises an anchoring body, a prestress steel strand, a bearing plate, a base plate, an elastic anti-loosening piece and a tensioning end anchorage device; the anchoring body is arranged in a foundation; the prestressed steel strand is arranged in the anchoring body, and the top end extends out of the anchoring body; the bearing plate is arranged on the prestressed steel strand in a sleeving manner and is arranged at the top of the anchoring body; the base plate is arranged on the prestressed steel strand above the bearing plate in a sleeving manner; the elastic anti-loosening piece is arranged between the base plate and the bearing plate in an abutting mode. The tensioning end anchorage device is arranged on the prestressed steel strand, and the bottom face of the tensioning end anchorage device makes contact with the base plate. The elastic anti-loosening piece serves as a force transmission piece to participate in tensioning construction of the prestressed steel strand, elastic potential energy is accumulated in the process, and after the tensioning end anchorage device is fixed, the anchor plate of the tensioning end anchorage device is continuously extruded through the base plate, so that the clamping piece of the tensioning end anchorage device is prevented from loosening.
本发明公开了一种防松脱的压力型预应力自检抗浮锚杆及其施工方法，属于地基基础施工技术领域，抗浮锚杆包括锚固体、预应力钢绞线、承压板、垫板、弹性防松件和张拉端锚具；锚固体设置在地基内；预应力钢绞线设置在锚固体内部，其顶端伸出锚固体；承压板套设在预应力钢绞线上，且设于锚固体顶部；垫板套设在承压板上方的预应力钢绞线上；弹性防松件抵接设置在垫板和承压板之间；张拉端锚具设置在预应力钢绞线上，其底面与垫板接触。本发明的弹性防松件作为传力件参与预应力钢绞线的张拉施工，在该过程中积蓄弹性势能，在张拉端锚具固定后，通过垫板对张拉端锚具的锚板进行持续挤压，防止张拉端锚具的夹片松脱。
