Basement anti-floating anchor end node circular truncated cone-shaped groove waterproof construction method
The invention relates to a waterproof construction method for a circular-truncated-cone-shaped groove of an end joint of an anti-floating anchor rod of a basement, and belongs to the technical field of anti-floating anchor rods. During layer pouring, the circular-truncated-cone-shaped groove is reserved in a certain range of the anchor rod joint, a water-swelling water stop strip is wound on the anti-floating anchor rod, asphalt factice is poured in a hot mode, and the waterproof construction method for the end joint of the anti-floating anchor rod of the basement is achieved. Grooves are formed in the base layer, micro-expansion concrete is used for blocking the grooves to enhance water resistance of the base layer, a saline-alkaline tolerant modified asphalt (SBS) waterproof roll additional layer is laid, anchor rods are wrapped in a hot melting mode around reinforcing steel bars, polyurethane is poured, waterproof construction at the joints is carried out, construction is convenient, and the waterproof effect is good. Compared with an existing common construction method that the end of the anti-floating anchor rod is coated with the cement-based capillary crystalline coating and a water stop strip is welded to the anchor bar, the construction method has the advantages that the construction period can be shortened, the construction cost is reduced, and the waterproof effect is better.
本发明涉及一种地下室抗浮锚杆端部节点圆台形凹槽防水施工方法，属于抗浮锚杆技术领域，本发明通过在浇筑在层时，在锚杆节点一定范围内预留圆台形凹槽，用遇水膨胀止水条缠绕在抗浮锚杆上，热灌沥青油膏，并用微膨胀混凝土封堵凹槽来增强基层防水，用铺设耐盐碱改性沥青(SBS)防水卷材附加层，在锚杆处环绕钢筋热熔包裹，并浇灌聚氨酯，进行节点处防水施工，施工方便，防水效果好；本发明的施工方法相对于目前常用的在抗浮锚杆的端头部位涂刷水泥基渗透结晶涂料和在锚筋上焊接止水片的施工方法，可缩短工期，降低施工成本，且防水效果更好。
