Grouting method for side wall construction joint in cover-excavation top-down method
The invention relates to a cover-excavation top-down method side wall construction joint grouting method, which comprises the following steps: 1) constructing an upper layer structure, pre-burying a grouting pipe in a side wall of the upper layer structure, exposing the upper end of the grouting pipe to the surface of the side wall of the upper layer structure, and extending the lower end of the grouting pipe downwards to the lower surface of the upper layer structure; (2) after concrete pouring of the upper-layer structure is completed and certain strength is achieved, earthwork of the lower-layer structure is excavated; (3) a lower layer structure is constructed, horn mouths are formed in the tops of the side walls, pouring is conducted, and concrete vibrating is conducted; (4) after the concrete of the lower-layer structure reaches the design strength, a pressure type grouting machine is adopted to be connected with the pre-buried grouting pipe of the upper-layer structure, and grouting is conducted on a construction joint between the upper-layer structure and the lower-layer structure; 5, when the grout overflows out of the grouting pipe, grouting is completed, and the surface of the side wall of the upper-layer structure is repaired. According to the method, grouting personnel conduct grouting on the concrete horizontal construction joint of the side wall of the lower layer and the brake shoulder at the bottom plate of the upper-layer structure, a traditional method that construction is assisted by an operation frame is avoided, construction is convenient, and grouting operation is facilitated.
本发明涉及一种盖挖逆作法侧墙施工缝注浆方法，1)施做上层结构，在上层结构侧墙中预埋注浆管，该注浆管上端暴露于上层结构侧墙表面，下端向下延伸至上层结构下表面；2)上层结构混凝土浇筑完成并达到一定强度后，开挖下层结构土方；3)施做下层结构,在侧墙顶部设置喇叭口并进行浇筑，进行混凝土振捣；4)待下层结构的混凝土达到设计强度后，采用压力式注浆机连接上层结构预埋注浆管，对上下层结构之间的施工缝进行注浆；5)当浆液溢出注浆管时，表示注浆完毕，修补上层结构侧墙表面，本方法注浆人员在上层结构底板处进行下层侧墙与刹肩混凝土水平施工缝注浆，避免了传统操作架体辅助施工的方法，施工方便，利于注浆操作。
