Culvert pipe prefabricated end plate and grouting bag combined plugging structure and construction method thereof
The invention discloses a culvert pipe prefabricated end plate and grouting bag combined plugging structure, and belongs to the technical field of civil engineering. The structure comprises a culvertpipe arranged at a water delivery position of a dam body, wherein the culvert pipe is filled with a row of grouting bags, a culvert pipe space except the grouting bags is filled with self-compacting concrete, culvert pipe prefabricated end plates are installed at the ends of the culvert pipe, at least two rows of grouting holes with downward end openings are formed in the dam body in the axial direction of the culvert pipe, one row of the two rows of grouting holes penetrate through the culvert pipe, and the end openings of the other grouting holes are positioned within 0.5 m from the peripheral side of the culvert pipe. The structure can improve the construction efficiency of culvert pipe plugging, reduces the construction difficulty, and avoids the situation that a novel water seepage channel is formed.
本发明公开了一种涵管预制端板及注浆囊袋组合封堵结构，属于土木工程技术领域。本发明包括于坝体输水处装设的涵管，涵管内填充有一排注浆囊袋，且除注浆囊袋之外的涵管空间内填充有自密实混凝土，涵管的端部安装有涵管预制端板，坝体内沿涵管轴向布设至少两排端口向下的灌浆孔，其中一排贯通涵管，另外的灌浆孔的端口处于涵管周侧0.5m之内。本发明可以提高涵管封堵的施工效率、降低施工难度，避免形成新的渗水通道。
