Rubber waterstops are widely used in various types of concrete structures. For example, in underground projects such as retaining dams, reservoirs, subways, culverts, and tunnels. In these projects, due to the inability to cast continuously, deformation of the foundation, or thermal expansion and contraction of concrete components caused by temperature changes, deformation joints and construction joints are often left during casting. These joints are required to prevent leakage. The problem must be solved by casting rubber waterstops at the deformation joints. It can not only prevent groundwater (or external water) from leaking into the building structure, but also prevent water in the building from leaking to the outside world. 1. Product Introduction
Waterstops utilize the characteristics of high elasticity and compression deformation of rubber to produce elastic deformation under various loads, thereby effectively tightening and sealing, preventing building water leakage, water seepage, and shock absorption and buffering. . In the general architectural design of larger projects, continuous pouring is not possible. Due to the deformation of the foundation or the thermal expansion and contraction of concrete components caused by temperature changes, construction joints, settlement joints, and deformation joints need to be left. Waterstops must be installed at these joints to prevent water leakage.
Waterstops are mainly used in foundation projects that are integrated with the concrete structure in construction joints and curved joints when concrete is cast in place, such as underground facilities, tunnel loopholes, water aqueducts, dams, liquid storage structures, etc. .
2. Product advantages
Excellent wear resistance, weather resistance, water resistance and chemical resistance.
, tear resistance, strong adaptability, good elastic recovery, and good water-stopping effect.
, has certain mechanical strength and large elongation.
3. Construction Points
When installing the waterstop, steel bars can be used to fix its position. If the waterstop needs to be overlapped, the two sides to be overlapped can be smoothed with a grinder first, and then glued with strong glue. The adhesive should be pasted, and the overlap length should be no less than 1.
4. Precautions
During construction, the accurate position of the waterstop and the pouring quality of the concrete must be ensured, and the two must be closely integrated.
During construction, the line must be stretched and positioned according to the specifications of the waterstop.
The edge of the waterstop must be compacted with flat steel and expansion screws, and sealed with sealing paste.
5. Storage and transportation
Storage products should be stored in a ventilated, cool, dry warehouse and away from fire sources.
. When transporting, it should be placed upright to avoid gravity extrusion.
