Abstract

The invention discloses a water stop belt positioning and connecting device and a construction method. The water stop belt positioning and connecting device comprises a mounting mechanism and two connecting mechanisms, wherein the mounting mechanism comprises two mounting plates and a first connecting limiting piece for locking the positions of the two mounting plates, and first cavities of the two mounting plates define a first annular limiting cavity; the two connecting mechanisms are arranged on the two opposite sides of a longitudinal water stop belt correspondingly, each connecting mechanism covers one of the two connecting positions of the local longitudinal water stop belt and an annular water stop belt, and each connecting mechanism comprises two connecting plates and a second connecting limiting piece for locking the positions of the two connecting plates; and each connecting plate comprises a first connecting section and a second connecting section, second cavities of the twofirst connecting sections define a second annular limiting cavity, and third cavities of the two second connecting sections define a third annular limiting cavity. According to the water stop belt positioning and connecting device and the construction method, the mounting difficulty of the longitudinal water stop belt is reduced, and the connecting difficulty and the mounting difficulty of the longitudinal water stop belt and the annular water stop belt are reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel waterproofing, and more specifically, to a positioning and connecting device for a waterstop and a construction method. Background technique [0002] After the tunnel is excavated and formed, it is necessary to spray the first lining concrete on the inner wall of the tunnel, and after the first lining concrete is formed, pour the second lining concrete. In order to ensure the construction quality, the tunnel is divided into several sections according to the set length, and the construction is carried out in sections. During the construction process, there will be construction joints at the junction of two adjacent construction sections. In the process of pouring the concrete for the second lining, each construction section is also constructed in sections. Typically, the tunnel is cylindrical, and each construction section is cylindrical. The pouring sequence of the second lining concrete in each...
