Anti-floating anchor rod for pre-tensioning method construction
The anti-floating anchor rod comprises a cushion layer used for being formed in an external pre-buried foundation pit in a pouring mode and a rod body used for being formed in the external pre-buried foundation pit in a pouring mode, a bottom anchor bearing plate is arranged at the top end of the rod body, the bottom anchor bearing plate is locally embedded in the cushion layer, and the bottom anchor bearing plate and the cushion layer are connected in a pouring mode. The rod body comprises an inner rod used for being connected with a cushion layer in a pouring mode and an outer rod used for penetrating out of a bottom anchor bearing plate, a steel strand is connected into the inner rod, a penetrating groove allowing the steel strand to penetrate through is formed in the outer rod, and a counter-force device used for providing prestress for the inner rod is arranged on the bottom anchor bearing plate. The problems that in the prior art, a post-tensioning method is adopted for construction, so that the hidden danger of water leakage of a bottom plate is likely to occur, and the durability of the bottom plate is not high are solved.
本发明公开了一种先张法施工用抗浮锚杆，包括用于在外界预埋基坑上浇筑成型的垫层和用于在外界预埋基坑中浇筑成型的杆体，所述杆体顶端端部设置有底部锚垫板，所述底部锚垫板局部嵌于垫层中且两者之间浇筑连接设置，所述杆体包括用于与垫层浇筑连接的内杆和用于贯穿出底部锚垫板的外杆，所述内杆中连接有钢绞线，所述外杆中设置有供钢绞线穿设的穿槽，所述底部锚垫板上设置有用于向内杆提供预应力的反力装置，本发明解决了现有技术中采用后张法施工导致底板容易出现渗漏水隐患且底板耐久性不高的问题。
