Wet joint construction method for prefabricated lane plates in tunnel
The invention relates to a wet joint construction method for prefabricated lane plates in a tunnel. The method comprises the steps that female head reinforcing steel bars with open ends are reserved at one ends of prefabricated lane plates, male head reinforcing steel bars with closed ends are reserved at the other ends of the prefabricated lane plates, and when the two prefabricated lane plates are spliced, the reserved female head reinforcing steel bars of the second prefabricated lane plate are opposite to the male head reinforcing steel bars of the first prefabricated lane plate; the second prefabricated lane plate reserved female reinforcing steel bars and the first prefabricated lane plate male reinforcing steel bars are inserted into 1/2 in a staggered manner; transverse steel barsin male steel bars of the first prefabricated lane plate are inserted into staggered positions of the female steel bars and the male steel bars; C-shaped reinforcing steel bars are inserted, and plugging and caulking of the lower gaps of the wing plates of the lane plates are performed; the C-shaped reinforcing steel bars are bent and the C-shaped reinforcing steel bars are welded with reserved female head reinforcing steel bars of the second prefabricated lane plate to form a closed ring; and cast-in-place concrete is poured, so that the two prefabricated slabs are connected into a whole. According to the tunnel internal prefabricated lane plate wet joint construction method, the transverse steel bars can be arranged in a full-length mode, cutting and welding are not needed, and the method adapts to internal narrow construction space; installation is convenient, connection is firm, construction is rapid, and economy and reasonableness are achieved.
一种隧道内部预制车道板湿接缝施工方法，在预制车道板一端留设端头开口的雌头钢筋、另一端留设端头闭合的雄头钢筋，两块预制车道板拼装时，使第二预制车道板预留雌头钢筋与第一预制车道板雄头钢筋相对；先使第二预制车道板预留雌头钢筋与第一预制车道板雄头钢筋交错插入1/2；再将第一预制车道板雄头钢筋里的横向钢筋翻入雌、雄头钢筋交错位置；插入C型钢筋，对车道板翼板下间隙进行封堵、嵌缝；将C型钢筋弯折并与第二预制车道板预留雌头钢筋焊接成闭合环；现浇混凝土浇筑，使两块预制板连接成整体。本隧道内部预制车道板湿接缝施工方法，横向钢筋可通长设置，无需截断、焊接，适应内部狭小施工空间；安装方便、连接牢固、施工快速、经济合理。
