Connecting structure and connecting method for anti-collision curbstone and lane plates in shield tunnel
The invention discloses a connecting structure of an anti-collision curbstone and a lane plate in a shield tunnel. The structure comprises a prefabricated lane plate, and is characterized in that laneplate annular steel bars are reserved in the prefabricated lane plate, and the annular steel bar is exposed out of the top of the prefabricated lane plate; prefabricated anti-collision curbstones arearranged above the prefabricated lane plate, grooves are formed in the bottoms of the prefabricated anti-collision curbstones, anti-collision curbstone annular steel bars are reserved, the lane plateannular steel bars are located in the grooves in the bottoms of the anti-collision curbstones, and longitudinal steel bars are inserted into the grooves in a penetrating mode. Concrete is poured intothe grooves, so that the prefabricated lane plate and the prefabricated anti-collision curbstones are firmly connected. According to the invention, the high-strength and high-rigidity wet joint is formed in a concrete pouring mode, high error correction capacity is achieved, and the phenomena of longitudinal flexibility and slab staggering of the shield tunnel can be effectively coped with.
本发明公开了一种盾构隧道内防撞侧石与车道板的连接构造，包括预制车道板，其特征在于预制车道板内预留车道板环型钢筋，且所述环形钢筋露出预制车道板的顶部；预制车道板上方设置预制防撞侧石，所述预制防撞侧石底部设置凹槽，并预留防撞侧石环型钢筋，所述车道板环型钢筋位于防撞侧石底部凹槽内，并在所述凹槽内穿插纵向钢筋；凹槽内灌注混凝土，使得预制车道板和预制防撞侧石形成牢靠连接。本发明采用灌入混凝土的方式形成高强度、高刚度的“湿”接头，且具有较强的误差修正能力，可以有效应对盾构隧道纵向柔性、存在错台的现象。
