Open cut tunnel deformation joint anti-seepage structure capable of bearing multidirectional dislocation and construction method
The invention belongs to the technical field of tunnel engineering, and particularly relates to an open-cut tunnel deformation joint anti-seepage structure capable of bearing multidirectional dislocation and a construction method. The open-cut tunnel deformation joint anti-seepage structure comprises first lining concrete and second lining concrete which are poured on the inner side wall of a tunnel in the length direction of the tunnel; a deformation joint is reserved between the first lining concrete and the second lining concrete, and an anti-seepage structure is arranged in the deformation joint. According to the method, the assembly type middle-buried steel edge rubber waterstop is arranged in the deformation joint, and dislocation between internal structures of the assembly type middle-buried steel edge rubber waterstop can adapt to plane dislocation or normal dislocation of the deformation joint without affecting the waterproof performance; therefore, the situation that the anti-seepage effect of the anti-seepage structure is weakened or even fails due to dislocation of the tunnels on the two sides of the deformation joint is avoided.
本发明属于隧道工程技术领域，尤其涉及承受多向错动的明挖隧道变形缝防渗结构与施工方法，包括：沿隧道长度方向浇注在隧道内侧壁上的第一衬砌混凝土与第二衬砌混凝土，所述第一衬砌混凝土与所述第二衬砌混凝土之间留有变形缝，所述变形缝内设置有防渗结构；本发明中，通过在变形缝内设置装配式中埋钢边橡胶止水带，装配式中埋钢边橡胶止水带内部结构之间的错动可以适应变形缝的平面错动或者法向错动而不会影响防水性能，从而避免了变形缝两侧隧道错动导致防渗结构的防渗效果减弱甚至失效的情况发生。
