Municipal road pipeline protection system and construction method
Technical Field
The invention relates to the technical field of municipal engineering road pipeline construction, in particular to a municipal road pipeline protection system and a construction method.
Background
Along with the continuous promotion of urban modernization, municipal works are important contents of urban development and important foundations of orderly operation of cities, municipal works such as municipal roads, bridges, underground comprehensive pipe galleries and comprehensive pipe networks are more and more, different underground pipe networks are often needed to be spanned in the municipal works, damage to the pipe networks is possibly caused by slightly careless construction operation, and extra construction risks and cost are increased. The pipe network which hinders the progress of the engineering is generally changed in a migration mode to reduce the influence on the engineering, but when underground pipelines which cannot be changed in a migration mode and structures are crossed and cannot be changed in a migration mode, an in-situ protection mode is generally adopted for carrying out in-situ protection. In particular to a comprehensive pipe network for permanent engineering, which is especially used for ensuring the operation and use of the pipe network and avoiding the damage to the pipeline, so that the prevention of the transition and the in-situ protection of the manufactured pipeline are extremely critical, and an effective protection thought is needed.
