Description

Technical Field

[0001] The utility model belongs to the technical field of utility tunnels, and particularly relates to a large-diameter pipeline support system for a manhole-type utility tunnel. Background Art

[0002] The urban underground pipeline integrated corridor, also known as "utility tunnel" or "common pipeline", is an intensive tunnel space built underground in the city, where two or more municipal pipelines such as electricity, communication, gas, heating, water supply and drainage are centrally laid in the tunnel, and special inspection openings, hoisting openings and monitoring systems are provided, and unified planning, design, construction and maintenance are implemented.

[0003] The manhole-type underground utility tunnel has a long and narrow structure, without a motor vehicle transportation passage, and only 3 hoisting openings of 10m×2m are reserved at the top of the utility tunnel to solve the hoisting and transportation of pipelines and equipment in the utility tunnel.

[0004] In the traditional construction plan for large-diameter spiral welded pipelines and trusses in the manhole-type underground utility tunnel, due to limited on-site space and narrowness in the tunnel, trusses are usually installed on both sides of the tunnel for floor-mounted installation. However, setting trusses on the masonry wall poses a certain risk of collapse. Moreover, the installation of large-diameter pipelines requires the setting of trusses and pipe clamps to match the length of the large-diameter pipelines. Therefore, a reasonable large-diameter pipeline support system needs to be built to provide for the rapid and reasonable installation and fixation of large-diameter pipelines.
