Underground diaphragm wall joint waterproof construction method and waterproof structure
The invention provides a waterproof construction method and a waterproof structure for an underground diaphragm wall joint, aims to solve the problems that waterproof construction of the underground diaphragm wall joint is difficult, and water resistance is easily influenced by expansion and contraction of the underground diaphragm wall joint and is easy to lose efficacy, and belongs to the technical field of water resistance. The waterproof structure for the underground diaphragm wall joint comprises a waterproof strip, a water guide plate and a protective layer, a triangular waterproof groove is formed in the soil back side of the underground diaphragm wall joint, the waterproof strip is embedded in the waterproof groove and divides the waterproof groove into an inner cavity and an outer cavity, the outer cavity is located on the outer side of the inner cavity, the inner cavity is filled with a water-soluble grouting material, and the outer cavity is filled with super-early-strength micro-expansive cement; the water guide plate is arranged on the outer side of the super-early-strength micro-expansive cement, the protective layer covers the outer side of the water guide plate, and the two ends of the protective layer are connected with wall blocks on the two sides of the underground diaphragm wall joint respectively. The service life of the waterproof structure is prolonged.
本发明是提供一种地下连续墙接缝防水施工方法及防水结构，以解决地下连续墙接缝防水施工困难，防水易受地下连续墙接缝伸缩影响而易失效的问题，防水技术领域。地下连续墙接缝防水结构，包括防水条、导水板和保护层；所述地下连续墙接缝的背土侧开设有三角形的防水槽，所述防水条嵌设在所述防水槽内，并将所述防水槽分隔成内腔和外腔，所述外腔位于所述内腔的外侧，所述内腔内填充设置水溶性灌浆材料，所述外腔内填充设置超早强微膨胀水泥；所述导水板设置在所述超早强微膨胀水泥的外侧，所述保护层覆盖设置在所述导水板的外侧，且两端分别与所述地下连续墙接缝两侧的墙块连接。本发明提高了防水结构寿命。
