DN150 Clamp Rubber Expansion Joint’Elevated Bridge Drainage Pipe Flexible Connection’
The official website of Shanghai Songjiang Vibration Absorber Group Limited introduces: Information on DN150 Clamp Rubber Expansion Joint ‘Elevated Bridge Drainage Pipe Flexible Connection’. Songjiang Group has designed a dedicated flexible connection product for urban elevated bridge drainage pipe systems, providing both shock absorption and noise reduction to protect the service life of drainage pipelines.
This product is mainly used for elevated bridge drainage pipelines, serving the purpose of a flexible connection to protect the long-term service life of drainage pipelines. Songjiang Group has supplied a batch of clamp-type rubber joints for the drainage system of the Minhang elevated road in Shanghai, as well as a batch for a municipal drainage system on Chongming Island. The product is made of natural rubber, exhibiting excellent aging resistance, with a normal service life of over 10 years. It is easy to install, has low maintenance costs, and is a new type of flexible connection product. However, its drawback is that it has a limited pressure-bearing effect, with a maximum pressure not exceeding 3 kg.

Road Surface Drainage Introduction: In order to rapidly eliminate standing water on the bridge deck, prevent rainwater from pooling and infiltrating the beams, thus affecting the durability of the bridge, drainage considerations are incorporated into the bridge design. Apart from longitudinal and transverse slope drainage on the bridge deck, a certain number of drainage pipes are installed to form a complete drainage system. The types of drainage pipes include metal drainage pipes, reinforced concrete drainage pipes, transverse drainage pipes, etc.
The number and diameter of drainage pipes on the bridge deck depend on the length, width, and longitudinal slope of the bridge. For urban bridges, overpasses, or highway bridges, a closed drainage system should be installed, directing drainage pipes directly to the ground. The aperture and quantity of drainage pipes are designed based on the rainfall intensity and catchment area of the region.
To swiftly remove standing water on the bridge deck and prevent rainwater from stagnating and penetrating the beams, the bridge design incorporates both longitudinal and transverse slope drainage. A specific number of drainage pipes are installed on the bridge deck to form a complete drainage system. The types of drainage pipes generally include metal drainage pipes, reinforced concrete drainage pipes, transverse drainage pipes, and closed drainage systems.
