Basement settlement joint waterproof structure leakage repairing method
The invention provides a basement settlement joint waterproof structure leakage repairing method which comprises the steps that foaming type silicate modified polyurethane is injected into a cavity between a middle-buried water stop belt and a backfill soil layer through each first grouting pipe till the first target grout amount is reached, and after foaming of the foaming type silicate modified polyurethane begins, the foaming type silicate modified polyurethane is injected into a cavity between the middle-buried water stop belt and the backfill soil layer; acrylic resin is injected into a cavity between the middle-buried type water stop belt and the foaming type silicate modified polyurethane through each second grouting pipe to reach a second target grout amount, and after the foaming type silicate modified polyurethane and the acrylic resin are solidified, a plurality of water-swelling water stop strips are embedded into the settlement joint in the length direction of the middle-buried type water stop belt. And a third grouting pipe is arranged between every two adjacent water-swelling water stop strips, so that polyurea grouting liquid is injected into a cavity between the water-swelling water stop strips and the middle-buried type water stop belt to a third target grout amount. The problem that other grout cannot be grouted after the grout of the waterproof structure expands due to the fact that the grouting amount of the grout in the settlement joint does not reach the standard or exceeds the standard is solved.
本发明提供一种地下室沉降缝防水结构渗漏修复方法，包括通过每个第一注浆管向中埋式止水带和回填土层之间的空腔内注入发泡型硅酸盐改性聚氨酯至第一目标浆液量，在发泡型硅酸盐改性聚氨酯开始发泡后，通过每个第二注浆管向中埋式止水带和发泡型硅酸盐改性聚氨酯之间的空腔内注入丙烯酸树脂至第二目标浆液量，在发泡型硅酸盐改性聚氨酯和丙烯酸树脂凝固后，将多个遇水膨胀止水条沿中埋式止水带长度方向嵌入沉降缝中，在相邻两个遇水膨胀止水条之间设置第三注浆管，以在遇水膨胀止水条与中埋式止水带之间的空腔内注入聚脲注浆液至第三目标浆液量。本发明解决沉降缝中浆液注浆量不达标或超标，导致防水结构浆液膨胀后其他浆液无法注浆的问题。
