SI JINGFENG / ZENG JIANNAN / XI SHUXIN

The invention discloses a waterproof structure for pipe gallery deformation joints and a construction method. The waterproof structure for the pipe gallery deformation joints comprises a middle-buriedtype steel-edge rubber water-stop belt, special-shaped auxiliary reinforcement steel bars, annular-direction fixing reinforcement steel bars, a slurry injection pipe, a slurry injection transverse pipe, a slurry injection box, a traction device, shearing force bars, a black iron pipe, a waterproof coiled material, a waterproof coiled material reinforcement layer, a waterproof coiled material concrete protective layer, polyurethane sealant, a deformation joint padding plate and a polythene foam plastic board isolating layer. According to the waterproof structure for the pipe gallery deformation joints, based on an existing construction structure, a slurry injection pipeline structure and the traction device are introduced, and the waterproof effect of the actual pipe gallery deformation joints and integrity of the pipe gallery structure are effectively improved.

本发明公开了一种用于管廊变形缝的防水结构及施工方法，包括中埋式钢边橡胶止水带、异形辅助钢筋、环向固定钢筋、注浆管、注浆横管、注浆盒、牵拉装置、剪力筋、黑铁管、防水卷材、防水卷材加强层、防水卷材混凝土保护层、聚氨酯密封胶、变形缝衬垫板、聚乙烯泡沫塑料板隔离层；基于现有施工结构，引入注浆管路结构及牵拉装置，有效提高实际管廊变形缝的防水效果及管廊结构整体性。
