Prefabricated reinforced concrete box culverts refer to box-shaped pipe joints prefabricated with reinforced concrete.In the actual application of the project, one or more square or rectangular box culverts are formed into a tunnel space, which integrates various engineering pipes such as electric power, communications, gas, heating, water supply and drainage, and has a special access port, hoisting port and monitoring system. The implementation of unified planning, design, construction and management of pipelines is called the urban underground integrated pipe corridor, which is the “lifeline” to ensure the operation of urban infrastructure.
