Cover-excavation top-down side wall construction joint waterproof node structure
The invention discloses a cover and excavation top-down side wall construction joint waterproof node structure which comprises a molded concrete wall and a brake shoulder concrete wall, the molded concrete wall is located below the brake shoulder concrete wall, and an upper layer horizontal construction joint is arranged between the molded concrete wall and the brake shoulder concrete wall; the brake shoulder concrete wall is provided with a first glue injection hole communicated with the groove, the molded concrete wall is provided with a second glue injection hole communicated with the upper-layer horizontal construction joint, and single-component polyurethane sealant is injected into the first glue injection hole, the groove, the upper-layer horizontal construction joint and the second glue injection hole. Single-component polyurethane sealant is injected into the first glue injection hole, the groove, the upper-layer horizontal construction joint and the second glue injection hole, the single-component polyurethane sealant is water-swelling water-stopping glue, then mortar is used for trowelling in the first glue injection hole, the upper-layer horizontal construction joint and the second glue injection hole, and the waterproof effect of the construction joint is ensured.
本发明公开了一种盖挖逆做侧墙施工缝防水节点构造，包括模筑混凝土墙和刹肩混凝土墙，所述模筑混凝土墙位于刹肩混凝土墙的下方，且所述模筑混凝土墙和刹肩混凝土墙之间设置有上层水平施工缝，所述刹肩混凝土墙上设有与凹槽连通的第一注胶孔，所述模筑混凝土墙上设有与上层水平施工缝连通的第二注胶孔，所述第一注胶孔、凹槽、上层水平施工缝、第二注胶孔注入有单组份聚氨酯密封胶。本发明向第一注胶孔、凹槽、上层水平施工缝、第二注胶孔注入有单组份聚氨酯密封胶，单组份聚氨酯密封胶为遇水膨胀止水胶，然后在第一注胶孔、上层水平施工缝、第二注胶孔内均通过砂浆抹平处理即可，确保施工缝防水效果。
