The water stop ring is refined from polymer inorganic water-absorbing expansion materials and rubber, which is a new type of waterproof engineering material. When exposed to water, it can absorb water and expand at a high expansion rate. It relies on its own expansion to squeeze the gap between the concrete and the tension bolts, which can completely stop the water. In actual construction, the operation is very flexible and convenient, which saves labor, time and money. Raw material costs. It is an updated product of welded waterstop plate (ring) and has been widely used in various projects. Product Features:
In traditional concrete wall formwork support, pull bolts or slatted tie rods are the main connectors connecting the two sets of vertical formwork inside and outside. Due to the tens of thousands of steel formwork used to fix it, Because the two tension bolts penetrate the wall throughout their length, the waterproof function of the waterproof concrete itself is lost. In order to solve this problem, a thick steel water stop plate is welded in the middle of the butt bolt. The disadvantage of this method is that it is difficult to inspect and guarantee the quality of the weld, and it is passive waterproofing. Once there are defects such as cracks, slag inclusions, burn-through, and pinholes in the weld, there will be subsequent water seepage paths that are difficult to cure.
This water stop ring is made of water-swellable rubber, and its performance reaches the various indicators in Part 3 of B/3 "Polymer Waterproof Materials" - Water-swellable rubber. It can be a round or rectangular piece. The general specifications of the strong body are outer diameter size and thickness. When in use, just put the water stop sheet tightly on the middle part of the pull bolt or lath type tie rod, and eventually it will be buried in the cast-in-place concrete to achieve the best waterproof effect.
Water stop ring technical indicators project standards:
Time required for water absorption expansion rate/maximum water absorption expansion rate (free state) 3 Heat resistance ℃ (no flow) Low temperature resistance and flexibility - ℃ (no flow around the round rod) Crack) water resistance (free state) immersion (overall expansion without fragments) tensile strength. Our company also produces rubber waterstop series, plastic waterstop series, pull bolt waterstop series, bridge bearing series, telescopic sewing series. Two-component polysulfide sealant, polyethylene closed-cell foam board, permeable hose, plastic blind ditch and other products used in various bridges, tunnels, water conservancy and highway projects.
