Anotace

This specification covers the minimum performance and material requirements for resilient connectors used for connections between precast reinforced concrete storm sewer structures and pipes, and between precast reinforced concrete pipe and laterals for storm drainage systems. These connectors are designed to prevent soil migration between the pipe and storm sewer structure, and between the pipe and lateral. Resilient materials for connectors, filler rings, and mechanical devices shall be tested, and shall conform to the specified values chemical resistance, tensile strength, elongation hardness, accelerated oven-aging, compression set, water absorption, ozone resistance, low-temperature brittle point, and tear resistance. The design of the connector and the pipe stubs are detailed.
