Abstract

The present invention discloses a lightweight prefabricated steel-concrete composite cable tunnel, which is used to solve the problems of long construction period, heavy weight, and inconvenient transportation and installation of cable tunnels in the prior art. The cable tunnel is composed of a fireproof layer, a skeleton layer, and a concrete layer from the inside to the outside; the skeleton layer is a cross-grid steel structure, the grid is filled with building fireproof panels, and a high-density polyethylene plastic film is applied to the outside of the concrete layer. Beneficial effects include: using the lightweight prefabricated steel-concrete composite cable tunnel in the embodiment of the present invention, the middle layer adopts a cross-grid steel structure as a load-bearing skeleton, the outer layer adopts lightweight aggregate concrete to transfer the load to the load-bearing skeleton, the inner layer is decorated with fireproof panels, and the outside is pasted with plastic film, which can be factory-produced and mechanized on-site assembled, and has multiple functions such as light weight, waterproof, fireproof, and anti-corrosion, which reduces the operation and maintenance costs of cable trenches, saves equipment investment, speeds up construction, and has greater economic benefits.
