The seepage-proofing reinforcing plate is arranged, so that the seepage diameter is prolonged, the bonding length between the spherical water stop and the concrete is prolonged, and the spherical water stop has good elasticity, can be well adapted to the deformation of the concrete, achieves the coordination and consistency, effectively reduces the shrinkage joint generated by the shrinkage deformation of the concrete, and further achieves the purpose of preventing the water leakage problem of the permanent joint.
The technical scheme of the utility model:
a high-pressure closed pore plate is arranged between permanent seams of the dam sections, a copper sheet water stop is arranged across the permanent seams, asphalt oil hemp is arranged in a copper water stop copper nose, two water stop ends of the copper sheet are respectively embedded into the dam bodies at two sides of the permanent seams, an inflatable ball-shaped water stop is arranged at two ends of the copper water stop and is embedded together, the inflatable ball-shaped water stop is a shaped product, and an inflatable cavity and an anti-seepage reinforcing plate are arranged.
The utility model has the advantages that: the structure adopts the inflatable spherical water stop and anti-seepage reinforcing plate arranged at the copper water stop end to adapt to deformation and compress the contraction joint between the spherical water stop and the concrete through inflation when the concrete contracts, thereby achieving the purpose of sealing the joint and stopping water. The construction is convenient, the cost is low, and the problem of water leakage of the permanent joint can be effectively prevented.
