Soil layer anti-floating anchor rod structure and construction method
The invention discloses a soil layer anti-floating anchor rod structure and a construction method. The anchor rod structure comprises anchor rod reinforcing steel bars, fixing supports, positioning clamps, a cement mortar grouting structure, a cushion layer, water stop rings and a basement concrete bottom plate; the positioning clamps tightly sleeve the anchor rod reinforcing steel bars and are welded to the anchor rod reinforcing steel bars at intervals; the anchor rod reinforcing steel bars are inserted into anchor rod holes; the fixing supports are welded to the outer side faces of the samehorizontal position of the anchor rod reinforcing steel bars; wholes formed by the fixing supports and the anchor rod reinforcing steel bars can be tightly embedded into the anchor rod holes; one setof fixing supports are welded at each interval; the upper portions of the anchor rod reinforcing steel bars are connected with the water stop rings, and the diameter of the water stop rings is largerthan that of an outer circle formed by anchor rod steel bars; an effective anchoring section of the anchor rod structure enters a rock stratum; and primary normal pressure cement mortar grouting andmortar supplementing are carried out, grouting is carried out until a full effect is achieved, and an anti-pulling test is carried out after anchor rod structure construction is completed. According to the structure and the method, the water stop rings are waterproof so that the anchor rod structure can be protected; the positioning clamps and the fixing supports can perform fixing and accurate positioning; and the fixing supports can also maintain the stability of the anchor rod structure.
本发明公开一种土层抗浮锚杆结构及施工方法，锚杆结构包括锚杆钢筋、固定支架、定位卡，水泥砂浆灌浆、垫层、止水环、地下室混凝土底板，定位卡紧套住锚杆钢筋，并与锚杆钢筋隔一段焊接一个，锚杆钢筋插入锚杆孔内，每根锚杆钢筋同一水平位置外侧面均焊接有型固定支架，固定支架和锚杆钢筋形成的整体能紧嵌进锚杆孔内，固定支架隔一段焊接一组，锚杆钢筋上部连接有止水环，止水环的直径大于锚杆钢筋形成的外圆直径，锚杆结构有效锚固段进入岩层。然后一次常压水泥砂浆灌浆、补浆，直至灌浆饱满，锚杆结构施工完成后进行抗拔试验。本发明的止水环，能防水，保护锚杆结构；定位卡和固定支架可固定、可准确定位；固定支架还可维持锚杆结构稳定。
