Waterproof structure of joint in open trench tunnel prefabricated lining with upper and lower blocks and construction method
The invention belongs to the technical field of underground structure engineering, and particularly relates to a waterproof structure of a joint in an open trench tunnel prefabricated lining with upper and lower blocks and a construction method. The waterproof structure comprises a lining ring; the lining ring is formed by splicing a prefabricated lining upper block and a prefabricated lining lower block which are oppositely arranged up and down; each of the prefabricated lining upper block and the prefabricated lining lower block comprises a structural plate and two side walls connected withtwo ends of the structural plate; and the two side walls of the prefabricated lining upper block are connected with the two side walls of the prefabricated lining lower block through concave and convex tenon structures respectively; side wall waterproof grooves extending in the longitudinal direction are formed in the outer sides of tenons on annular joint faces in the side walls provided with thetenons; and side wall waterproof rubber strips are pasted in the side wall waterproof grooves. According to the waterproof structure and the construction method, waterproof materials are saved, the construction quality is high, certain procedure crossing can be achieved between waterproof construction and prefabricated lining assembly, the lining construction speed is increased, and the overall construction period of an open trench tunnel is shortened.
本发明属于地下结构工程技术领域，具体涉及一种上下分块的明挖隧道预制衬砌拼缝防水结构及施工方法，包括衬砌环，所述衬砌环是由上下相对设置的预制衬砌上分块和预制衬砌下分块拼接而成；所述预制衬砌上分块和所述预制衬砌下分块均包括结构板以及与所述结构板两端连接的两侧墙，所述预制衬砌上分块的两侧墙与所述预制衬砌下分块的两侧墙分别通过凹凸榫结构连接；于设有凸榫的侧墙的环向拼缝面上的凸榫外侧设置沿纵向延伸的侧墙防水凹槽，且所述侧墙防水凹槽内粘贴有侧墙防水胶条。本发明不仅节约防水材料，施工质量较高，并且防水施作可以和预制衬砌拼装实现一定的工序交叉，加快衬砌施做速度，缩短明挖隧道整体工期。
