Waterstops Heilongjiang steel putty rubber water stop market 400-0318-993 

 Product Description 
 Tunnel and Underground Engineering of the water stop is a concrete lining seam (construction joints, expansion joints and settlement joint) built-in water stop. Bypass, flange, expansion of rubber and stop slurry treatment with the composition (Figure). Its characteristics: First, in the water stop the drainage channels connected by a lower part of the tunnel drainage system, waterstops lateral seepage pressure; paste in the three seam on both sides of the water stop flange water swelling rubber strips to prevent lateral flow of water seepage along the water stop. The water stop for three sewn in the lining of the tunnel and underground engineering waterproof.

 Sealing: 
 This product is widely used in various types of concrete and cast-in-place concrete structure. For example: culverts, dams, reservoirs, inverted siphon, subway, culverts, tunnels, hydropower, thermal power plants and so on. In these works, sometimes not continuous casting, or will cause expansion and contraction of concrete structures due to ground deformation and temperature changes and other reasons, should be left in the pouring deformation joints, construction joints. Seam seepage, leakage through the rubber water-stop approach to solve. It can prevent groundwater (or outside water) leaking into the building structure, but also to prevent water leakage inside the building to the outside world, with favorable results. 
 (2) water-stop design and selection: 
 The choice of 1.1 water stop 
 Should be based on a hierarchy of importance of the structures, deformation joint deformation and water pressure, water-stop, so that (should be) taken into account to determine the work environment, economic factors and other conditions. 
 1.2 water stop material choice according to the following provisions 
 1.2.1 Under normal circumstances, multi-use natural rubber water stop. 
 1.2.2 When the case of weak acid, alkali, corrosive media, should use neoprene waterstops. 
 1.2.3 should be selected when the case of oil medium nitrile rubber water stop. 
 1.2.4 When possible case of mold erosion, should be considered mold rubber water-stop, their grades should reach more than two and two. 
 1.2.5 When the use temperature: -25 ° C ~ 60 ° C, selection of neoprene waterstops. 

 -35 ℃ ~ 60 ° C, use of natural rubber water stop. 

 -40 ° C ~ 60 ° C, use EPDM rubber water-stop. 
 1.3 the waterstops width and thickness of options to consider the following three factors 
 1.3.1 the level of deformation joint and vertical deformation 
 1.3.2 The water pressure 
 1.3.3 structure of the section size 
 (3) water-stop: (1). Buried in rubber water stop (2) backing with rubber water stop (3) (4) grouting steel side rubber waterstops waterstops and other forms. 
 Rubber water-stop construction and installation of: 
 The water stop pouring concrete pouring process, some or all buried in the concrete. In pointed stone and reinforced concrete, in waterstops positioning and concrete pouring process, should pay attention to the installation location method and pouring pressure to avoid the water stop was punctured. As the tear strength of rubber is 3-5 times lower than the tensile strength, so if the water stop was punctured will greatly reduce the water stop the ability to resist external forces. Therefore, in the construction of extra attention. Specific precautions are as follows: 
 1.1 in the steel banding and formwork, the water stop must be taken to a reliable fixed measures to avoid displacement occurred in the pouring of concrete to ensure that the correct location of waterstops in concrete. 
 1.2 fixed water stop, only perforated holes allow parts of the water stop shall not damage the body part. 1.3 
 Construction specifications for fixed water-stop shall be designed requirements, commonly used fixation methods: the use of a fixed set of additional reinforced; fixed special fixtures; wire and template fixed. Regardless of the fixed method. 
 Must be guaranteed the waterstops accurate positioning without damaging the effective part of the water-stop, convenient concrete pouring. 
 (5) after-sales service: 
 The water stop at the factory should be connected as a whole, as a result of the use of the environment or transport conditions and restrictions required in the field connection, we can always send someone to the field joints and to guide the installation. Site joints by hot press curing glue, and the appearance of smooth, bright and clean.
