Description

Technical Field

[0001] The present invention relates to the technical field of underground integrated pipe corridors, and in particular to a block-type underground integrated pipe corridor. Background Art

[0002] Underground utility corridors are public tunnels built underground in cities for laying municipal pipelines such as electricity, communications, radio and television, and water supply. Underground utility corridors can effectively prevent the zipper road phenomenon, so that technicians do not need to repeatedly dig up the road surface. They can repair, maintain, expand and transform various pipelines in the corridors, and greatly reduce the time for pipeline repairs.

[0003] After searching, the publication number CN211257071U discloses a prefabricated pipe gallery, which includes a plurality of pipe gallery body prefabricated parts spliced ​​in sequence along the radial direction of the pipe gallery corridor; wherein each pipe gallery body prefabricated part includes an upper gallery body and a lower gallery body; wherein the upper gallery body includes a first cross beam, a first vertical beam, a first embedded steel plate and a first adhesive layer; wherein the lower gallery body includes a second cross beam, a second vertical beam, a second embedded steel plate and a second adhesive layer, the second vertical beam is connected to the second cross beam, and is arranged in the middle and both sides of the second cross beam, the second embedded steel plate is arranged on the peripheral side of the second vertical beam, and is located at one end of the second vertical beam away from the second cross beam, and the second adhesive layer is arranged at one end of the second vertical beam away from the second cross beam; wherein the first embedded steel plate is welded to the second embedded steel plate, and the first adhesive layer is adhered to the second adhesive layer, so that the first vertical beam is connected to the second vertical beam, and the upper gallery body is at the top of the lower gallery body. The prefabricated pipe gallery has strong deformation resistance and good waterproof performance.
