Construction method for multi-node anti-seepage treatment of unbonded prestressed anti-floating anchor rod
The invention relates to the technical field of building waterproof construction, and discloses a construction method for multi-node anti-seepage treatment of an unbonded prestressed anti-floating anchor rod, which comprises the following steps: S1, constructing the unbonded prestressed anti-floating anchor rod; the method comprises the steps of foundation pit excavation, anchor rod hole site measurement and placement, follow-pipe drilling and hole forming to the designed depth, drill pulling and grouting, anchor rod anti-pulling rod piece imbedding, grouting, anti-pulling experiment detection and acceptance inspection, S2, bottom plate waterproof construction, S3, BW water swelling sealing strip embedding, S4, anchor rod end waterproof joint treatment and S5, external anti-leakage sealing. Through the construction technology of a waterproof rubber lantern ring, a sealing water stop strip, a polyurethane waterproof coating, a capillary crystalline waterproof coating, a sealing water stop strip and a concrete column pier, the problem that when an anti-floating anchor rod is used due to the fact that the underground water level is high or the self weight of a structure is insufficient in a project adjacent to the lake edge, the top and a bottom plate of the anchor rod are prone to leakage due to rising of the underground water level is solved. The probability of leakage of the top and the bottom plate of the anchor rod is greatly reduced, and the later leakage stopping cost is reduced.
本发明涉及建筑防水施工技术领域，公开了一种无粘结预应力抗浮锚杆多节点防渗漏处理的施工方法，包括以下步骤：S1：无粘结预应力抗浮锚杆施工，基坑挖掘－锚杆孔位测放－跟管钻进成孔至设计深度－拔钻注浆－置入锚杆抗拉杆件－灌浆－抗拔实验检测－验收，S2：底板防水施工，S3：埋设BW遇水膨胀密封条，S4：锚杆端部防水节点处理，S5：外部防渗漏封闭。通过防水橡胶套环、密封止水条、聚氨酯防水涂料、渗透结晶防水涂料、密封止水条和混凝土柱墩的施工工艺，解决工程邻近湖边、地下水位较高或结构自重不足而用抗浮锚杆时，地下水位上升引起锚杆顶部和底板容易渗漏的问题，大幅度降低了锚杆顶部和底板渗漏的概率，减少了后期堵漏成本。
