| a:The rubber hardness range is the recommended value for reference in the design of JY type waterstops for different immersed pipeline projects. | ||||||
| b:Rubber to metal adhesive items are only applicable to waterstops compounded with steel edges. | ||||||
| c:The rubber to cord adhesion item is only applicable to JX type waterstops compounded with cord fabric. | ||||||
| Note: If there are other special needs, the inspection items can be appropriately added by agreement between the supplier and the supplier. The water swelling rubber part of the rubber composite waterstop shall comply with the provisions of GB/T 18173.3. | ||||||
Rubber waterstops are mainly used in foundation projects that integrate concrete structures into construction and deformation joints during cast-in-place concrete pouring, such as underground facilities, tunnels, culverts, water conveyance aqueducts, water retaining dams, and liquid storage structures.
