Description
Technical Field
The utility model relates to a tunnel water-stopping fixing device, and belongs to the technical field of underground tunnel construction.
Background
At present, in the second-stage lining construction process of a tunnel, in order to avoid the reasons of temperature expansion and contraction, foundation settlement, earthquake collision and the like, a structural joint is arranged between every 10-15 m. Because the waterproof treatment of the structural joint of the concrete is very difficult, especially the problems of uneven settlement or expansion with heat and contraction with cold are very difficult to completely solve, a water stop copper sheet or a rubber water stop belt needs to be arranged at the parting position. The water-stopping copper sheet (rubber water-stopping belt) is partially or completely embedded in the concrete pouring process. Because the installation position and the effect of the water stop copper sheet (the rubber waterstop) directly influence the water stop effect of the culvert (the tunnel) parting, the water stop copper sheet (the rubber waterstop) needs to take reliable fixing measures so as to ensure the correct position of the water stop copper sheet (the rubber waterstop) in concrete.
The commonly used fixing mode of the water stopping copper sheet (rubber water stopping belt) comprises the following steps: fixing by using additional steel bars, fixing by using special fixtures, fixing by using lead wires and templates and the like. However, no matter which fixing method is adopted, the effective waterproof part of the water stop belt must not be damaged when the water stop copper sheet (rubber water stop belt) is fixed. How to guarantee smooth accurate fixed of stagnant water copper sheet (rubber waterstop), and guarantee that stagnant water copper sheet (rubber waterstop) does not suffer damage is the technical problem that needs to solve urgently.
However, in the actual construction process, in order to prevent the displacement of the water-stopping copper sheet (rubber water-stopping belt) during the concrete pouring, holes are punched on the allowed part of the water-stopping copper sheet (rubber water-stopping belt) only when the steel bars and the formwork are bound or fixed by a large mechanical steel plug clamp. Although the fixation of the water-stopping copper sheet (rubber water stop) is solved in the prior art, the water-stopping copper sheet (rubber water stop) is damaged to a certain extent by punching holes. In recent years, a plurality of scholars invent clamps for water stop copper sheets (rubber water stop belts), but the construction steps are complicated, and meanwhile, fixing members and the clamps need to be poured in secondary concrete, so that the construction speed is low, the fixing members and the clamps cannot be reused, the construction technical requirement is high, and the construction cost is too high. The large mechanical steel plug clamp is only suitable for the construction of culverts (tunnels) with larger hole diameters, and has higher one-time investment cost and low repeated utilization rate.
