Construction method of lower groove anti-floating anchor rod pile head
The invention relates to the technical field of anti-floating anchor rod construction, and aims to solve the problems that in the prior art, in order to guarantee the straight anchoring length of anti-floating anchor rod steel bars in a raft, a groove is designed in the raft, so that the forming quality of a concrete cushion layer is difficult to control, and the raft is prone to leakage in the later period that the waterproof performance of the anti-floating anchor rod pile head position is weak. The invention provides a construction method for a lower groove anti-floating anchor rod pile head. The construction method comprises the steps that a lower groove is excavated; cleaning the end of the anti-floating anchor rod; manufacturing a lower groove shaping mold; mounting a cushion brick and a lower groove shaping mold; the lower groove shaping mold is pressed through a pressing mold; cushion layer concrete is poured; sleeving the longitudinal bars of the anti-floating anchor with a sleeve, and embedding the lower end of the sleeve into the cushion concrete; after the cushion concrete is formed, the pressing mold and the lower groove shaping mold are taken out, and the sleeve is filled with a capillary crystalline waterproof material; paving a waterproof coiled material on the cushion layer, sleeving a rubber water stop strip on the sleeve, and constructing a waterproof protective layer on the waterproof coiled material; the waterproof effect of the anti-floating anchor pile head can be effectively improved, and the leakage risk is reduced.
本发明涉及抗浮锚杆施工技术领域，旨在解决现有技术为保证抗浮锚杆钢筋在筏板中直锚长度，筏板设计下凹槽，导致混凝土垫层成型质量控制难，抗浮锚杆桩头位置防水薄弱后期筏板容易渗漏的问题，提供一种下凹槽抗浮锚杆桩头施工方法，包括开挖下凹槽；清理抗浮锚杆端头；制作下凹槽定型模具；安装垫砖和下凹槽定型模具；通过压紧模具压紧下凹槽定型模具；浇筑垫层混凝土；在抗浮锚杆纵筋外部套设套管，将套管下端埋入垫层混凝土；垫层混凝土成型后取出压紧模具和下凹槽定型模具，在套管内充填渗透结晶防水材料；在垫层上铺贴防水卷材，在套管上套设橡胶止水条，在防水卷材上施工防水保护层；本发明能有效提高抗浮锚杆桩头防水效果，减小渗漏风险。
