The PVC plastic waterstop is a waterstop product made of high-grade polyvinyl chloride resin and various chemical additives, which are mixed, granulated and extruded.

Principle

It makes full use of the elastic deformation characteristics of polyvinyl chloride resin to prevent leaks and seepage in the joints of building structures, and has the characteristics of corrosion resistance and durability.

Use

The PVC plastic waterstop is mainly used for the basic engineering which is integrated with the concrete in the construction joint and the deformation joint when the concrete is poured. Such as tunnels, culverts, diversion aqueducts, dams, liquid storage structures, underground facilities, etc. The plastic waterstop takes full advantage of the elastic deformation characteristics of the polyvinyl chloride resin to prevent leaks and seepage in the joints of the building structure, and has the characteristics of corrosion resistance and durability.

Specification

280 × 6, 300 × 4, 300 × 6, 300 × 8, 300 × 10, 350 × 8, 350 × 10 and so on.

Construction Method:

The construction method of the PVC plastic waterstop is the same as the construction method of the rubber waterstop. When it is buried, it should be flattened with the concrete interface, the joint part is bonded and fastened, and the concrete should be fully shocked with appropriate force during the burying process to make it fit well with the concrete to obtain the best water stopping effect. .

Construction Notes:

During the construction process, due to the presence of many sharp-pointed stones and steel bars in the concrete, care should be taken to avoid mechanical damage to the plastic waterstop.

When positioning the plastic waterstop, it should be flattened with the concrete interface, and the phenomenon that the waterstop is turned over and twisted can not occur. Otherwise, it should be adjusted in time. When pouring the fixed waterstop, prevent the waterstop from shifting and affect the water stopping effect. Waterstop joints can be bonded and heat welded to ensure a firm joint. Pay attention to the full shock during the pouring of concrete to achieve a full combination of the water stop belt and concrete.

The classification of rubber waterstops includes: medium-buried rubber waterstops, externally-applied rubber waterstops, medium-buried groutable waterstops, and water-swellable rubber waterstops. The rubber waterstop uses a metal plate waterstop that changes the water's penetration path and extends the water's penetration path. In the construction environment where the leakage water may contain corrosive components, the rubber waterstop can provide a certain anti-corrosion effect. In the protection project, the rubber waterstop is used to ensure the protection effect of the project. Rubber waterstops are also commonly used in projects with high impermeability requirements and small areas. For example, the rubber waterstops such as casting pits and electric furnace pits in smelters are made of natural rubber and various synthetic rubbers. Various additives and fillers, which are plasticized, kneaded and pressed, have many varieties and specifications, such as bridge type, mountain type, P type, R type, U type, Z type, B type, T type, H Type, E type, Q type, etc. The water-stopping material has good elasticity, wear resistance, aging resistance and tear resistance, is suitable for deformation ability, and has good waterproof performance, and the temperature is in the range of -45 ° C - + 60 ° C. This product should not be used when the temperature exceeds +70 ° C and is strongly oxidized or attacked by organic solvents such as oils.

Waterstop Use

It is mainly used for concrete casting and other construction of expansion joints such as infrastructure projects, underground facilities, tunnels, sewage treatment plants, water conservancy, gates, subways at the bottom of dams.
