Cover-excavation top-down side wall waterproof connecting structure
The invention discloses a cover and excavation top-down side wall waterproof connecting structure which comprises a concrete side wall, the concrete side wall is composed of a first construction concrete side wall and a second construction concrete side wall, and a construction joint is arranged between the bottom face of the first construction concrete side wall and the top face of the second construction concrete side wall. The construction joint is of a multi-stage step-shaped structure which is inclined upwards from the upstream face to the downstream face, each step face of the multi-stage step-shaped structure is an inclined face, an anti-seepage coating layer is sprayed on the outer wall of the concrete side wall at the downstream face of the construction joint, and a self-adhesion coiled material reinforcing layer is arranged on the outer wall of the concrete side wall at the upstream face of the construction joint. And a plurality of water expansion water-stop strips are arranged in the construction joint in a full-length manner. By the adoption of the structure construction joint, the compactness of post-poured concrete on the upstream face can be remarkably improved, and the waterproof effect of the structure is greatly improved.
本发明公开了一种盖挖逆作侧墙防水连接结构，包括混凝土侧墙，混凝土侧墙由先施工混凝土侧墙和后施工混凝土侧墙组成，施工缝设置在先施工混凝土侧墙的底面和后施工混凝土侧墙的顶面之间，施工缝为由迎水面至背水面斜向上的多级台阶形结构，多级台阶形结构的各台阶面为斜面，在施工缝的背水面处的混凝土侧墙外壁上喷涂有防渗涂料层，在施工缝的迎水面处的混凝土侧墙外壁上布设有自粘卷材加强层，在施工缝内通长设置有多道水膨胀止水条。采用本结构施工缝能够显著提高迎水面后浇混凝土的密实性，极大的提高了结构的防水效果。
