2806PVC止水带 背贴式。280×6PVC止水带 背贴式
PVC plastic waterstop is composed of grade PVC resin and various chemical additives, water mixing, granulating and extruding process and made with products.
It takes full advantage of the elastic deformation property of PVC resin, and has the function of anti leakage and seepage prevention in the joint of building structure, and has the c h a racteristics of corrosion resistance and good durability.
PVC plastic water stop belt is mainly used for concrete pouring, it is installed in the construction joints and deformation joints, and concrete as one of the basic works. Such as tunnel, culvert, aqueduct, dam, reservoir structures, underground facilities, etc.. The plastic water stopping strip takes full advantage of the elastic deformation property of the polyvinyl chloride resin, and has the function of leakage prevention and seepage prevention in the joint of the building structure, and has the c h a racteristics of corrosion resistance and good durability.
280 x 6，300 x 4300 x 6300 x 8300 x 10350 × 8350 × 10 etc.
The construction method of PVC plastic water stop belt is the same as the construction method of rubber water stop belt. In the pouring buried to make it smooth and fit the concrete interface, the joint part of the adhesive fastening, pouring process to buried in an appropriate capacity of fully vibrating concrete, the good combination with concrete, in order to obtain the best sealing effect.
In the process of construction, the users should pay attention to avoid mechanical damage to the plastic stop belt because of the many sharp stones and reinforcing bars in the concrete.
In the positioning of plastic water stop, to make it and the concrete interface leveling, can not appear water stop, flip, distortion and so on, otherwise should be timely adjustment. When pouring the fixed water stop belt, the water stop belt should be prevented from shifting and the sealing effect will be affected. The joint of the water stop belt can be firmly secured by bonding and heat welding. In the process of pouring concrete, attention should be paid to the full shock and tamping so as to achieve the full combination of the water stopping belt and the concrete.
