Treatment method for water leakage of settlement joint of underground passage
The invention provides a treatment method for water leakage of a settlement joint of an underground passage, which belongs to the technical field of constructional engineering and comprises the steps of foundation treatment, hole arrangement and drilling, primary high-pressure polyurethane grouting, pre-burying of a secondary high-pressure polyurethane pouring cavity, embedding of expansion rubber and pouring of polymer concrete, secondary high-pressure polyurethane pouring and polyurethane elastic waterproof sealing. And a polymer mortar cover. According to the method, an elastic rubber reinforced water-swelling type water-stop belt can be formed, and it can be effectively ensured that the settlement joint keeps the waterproof function to the maximum extent in the long-term operation process of an underground passage; and the problems of inconvenient passage of passengers, structural damage to concrete, shortened service life of the concrete structure and the like caused by water seepage of the underground passage can be fully avoided.
本发明提出了一种地下通道沉降缝漏水的处理方法，属于建筑工程技术领域，包括基础处理，布孔钻孔，一次高压灌浆聚氨酯，预埋二次高压灌注聚氨酯空腔，嵌填膨胀橡胶并浇筑聚合物混凝土，二次高压灌注聚氨酯，聚氨酯弹性防水密封，聚合物砂浆封面。本方法可以形成“弹性橡胶加强并遇水膨胀型止水带”，可以有效确保沉降缝在地下通道的长期运营过程中最大限度的保持防水功能，能充分避免地下通道渗水造成的旅客通行不便和对混凝土造成的结构损伤破坏和混凝土结构寿命缩短等问题。
