Waterproof structure and method for top of concrete side wall of underground building in cover-excavation construction method
The invention discloses a waterproof structure and method for the top of a concrete side wall of an underground building in cover-excavation construction method. The waterproof structure comprises a top plate and a side wall, a construction joint is arranged between the top plate and the side wall, the construction joint is provided with a water stop belt perpendicular to the construction joint, the top plate is provided with a plurality of embedded pipes along the construction joint, end openings of the embedded pipes are aligned with the construction joint and arranged between the water stop belt and the upstream face, and concrete is poured into the embedded pipes from top to bottom to form the side wall. According to the waterproof structure and method, grouting is carried out through the embedded pipes arranged on the top plate, the embedded pipes are arranged from top to bottom and are aligned to the construction joint between the water stop belt and the upstream face, meanwhile, the adjacent embedded pipes arranged side by side serve as exhaust pipes so that the space outside the water stop belt can be densely filled with concrete, no through seam trace exists, air in the gap is exhausted, the density of the concrete is improved, meanwhile, the situation of cold joints caused by secondary grouting is avoided, and the quality problem of leakage of construction joints of the top plate and the side wall is solved.
本发明公开了一种地下建筑盖挖工法混凝土边墙顶部防水结构与方法，包括顶板与侧墙，所述顶板与所述侧墙之间设置施工缝，所述施工缝设置垂直于所述施工缝的止水带，所述顶板沿着所述施工缝设置多根预埋管，所述预埋管的端口对准所述施工缝并设置在所述止水带与迎水面之间，所述预埋管自上而下灌注混凝土形成所述侧墙。本发明通过设置在顶板的预埋管进行注浆，将预埋管自上而下设置并对准止水带与迎水面之间的施工缝，同时将并列设置的相邻的预埋管作为排气管使用，使得混凝土能够将止水带外侧空间填充密实，无通缝痕迹，并令该缝隙的空气排清，提高混凝土密实度，同时避免二次注浆产生冷缝的问题，解决顶板与侧墙施工缝的渗漏质量问题。
