- Commodity name: Shield Waterstop
- Commodity ID: 1452942566843109376
Shield waterstop is currently the mainstream material used for sealing waterstop of assembled tunnel segments at home and abroad. It is composed of a single porous EPDM rubber and a water-swellable rubber. The multi-void elastic rubber gasket can reduce the compressive stress during assembly, and has good compressive and biased stress relaxation performance, which can prolong the service life.
Product introduction
Shield waterstop is currently the mainstream material used for sealing waterstop of assembled tunnel segments at home and abroad. It is composed of a single porous EPDM rubber and a water-swellable rubber. The multi-void elastic rubber gasket can reduce the compressive stress during assembly, and has good compressive and biased stress relaxation performance, which can prolong the service life. This composite rubber gasket has a double-safety sealing and water-stop function. When there is a certain gap and offset between the segments during the construction, the product can also effectively ensure the sealing and water-stop effect.
Features
(1) It has good elasticity, aging resistance, chemical resistance and ozone resistance.
(2) In a wide temperature range, it can exert excellent water-stop performance and excellent weather resistance.
(3) It is suitable for construction in low temperature environment and cold area.
Scope of application
The product is suitable for joint waterproof sealing of assembled underground engineering pipelines. Mainly used in infrastructure projects, underground facilities, tunnels, culverts, water conservancy, subway and other projects. This product has been widely used in the waterproof sealing of joints in the shield construction of subway rail transit in Shanghai, Beijing, Tianjin, Guangzhou and other places.
