針对隧道村砌渗漏病害,在宝成綫若干隧道中使用膨胀水泥喷浆、勾縫等及深孔镄眼排水法进行了整治。茲簡略介紹如下: 一、喷浆防水法喷浆法在工程补程与防水层上,国内外采用較多。近几年来,国内把它作为水垻及船底防水层已很普遍,但是,在隧道工程上应用尙少。 In view of the leakage of tunnel masonry, some tunnels in the Baocheng line were rectified by the use of expansion cement shotcreting, jointing, etc., and deep-hole hole drainage. The brief introduction is as follows: First, the spray-water spray method is widely used at home and abroad in the engineering repair and waterproof layer. In recent years, it has become common in China to use it as a water jacket and bottom waterproof layer, but there are few applications in tunnel construction.
