Pressure type prestress anti-floating anchor rod and construction method thereof
The invention relates to the technical field of constructional engineering, in particular to a pressure type prestress anti-floating anchor rod which comprises a threaded steel bar, and an anchoring device, a pre-tightening device, a water stop ring, an assembly type support, a bearing body and an end cap which are connected from top to bottom along the threaded steel bar. The anchoring device, the pre-tightening device, the assembly type support, the bearing body and the end cap are detachably connected to the threaded steel bar, and the water stop ring is fixed to a drilling hole opening. A steel pipe is arranged between the pre-tightening device and the assembly type support, and a pressure-bearing anchoring section is formed between the bearing body and the cushion layer. According to the technology, the steel pipe only needs to be installed within a certain depth range of the orifice, the prestress can be balanced through the bonding force of the steel pipe and the grouting body interface, the requirement for the construction quality of the orifice is not high, and the prestress applying process is greatly simplified.
本发明涉及建筑工程技术领域，特别涉及一种压力型预应力抗浮锚杆包括螺纹钢筋，以及沿螺纹钢筋由上至下连接的锚固装置、预紧装置、止水环、装配式支架、承载体以及端帽，锚固装置、预紧装置、装配式支架、承载体以及端帽可拆卸连接于螺纹钢筋，止水环固定于钻孔孔口处；预紧装置和装配式支架之间设置有钢管，承载体至垫层之间形成承压锚固段。本发明技术只需要在孔口一定深度范围内安装钢管，依靠钢管与注浆体界面的粘接力即可平衡预应力，对孔口的施工质量要求不高，大大简化预应力施加流程。
