Plastic waterstop functions and Principle: Plastic waterstop is a waterstop material made of polyvinyl chloride resin and various additives through mixing, granulation, extrusion and other processes. This product uses the elastic deformation characteristics of elastomer materials to prevent leakage and seepage in the joints of building structures, and has the characteristics of corrosion resistance and good durability. Plastic waterstops are mainly used for foundation projects that are installed in construction joints and deformation joints and are integrated with the concrete during concrete pouring. Such as tunnels, culverts, diversion aqueducts, dams, liquid storage structures, underground facilities, etc.
Construction method of plastic waterstop: The construction method of plastic waterstop is the same as that of rubber waterstop. When pouring and burying, the interface with the concrete should be flat and the joint portion should be bonded and tightened. During the pouring and burying process, the concrete should be fully vibrated with appropriate force to make it well combined with the concrete to obtain the best water-stopping effect.
Precautions for plastic waterstop construction:
During the construction process, because there are many sharp-edged stones and steel bars in the concrete, care must be taken to avoid mechanical damage to the waterstop.
. When positioning the plastic waterstop, make sure that the interface with the concrete is flat and smooth, and the waterstop should not be flipped or twisted, otherwise it should be adjusted in time.
.When pouring the fixed waterstop, the waterstop should be prevented from deflecting and affecting the waterstop effect.
. Plastic waterstop joints can use bonding, heat welding and other methods to ensure that the joints are firm.
During the process of pouring concrete, pay attention to sufficient vibration to achieve full combination of waterstop and concrete.
