Description
Technical Field
The utility model belongs to the technical field of the utility model and specifically relates to a cast-in-place utility tunnel formwork system in big section multicavity is related to.
Background
The utility tunnel is an underground city pipeline utility tunnel, namely, a tunnel space is built underground the city, various engineering pipelines such as electric power, communication, gas, heat supply, water supply and drainage and the like are integrated, a special overhaul port, a lifting port and a monitoring system are arranged, unified planning, unified design, unified construction and management are implemented, and the utility tunnel is an important infrastructure and a 'lifeline' for guaranteeing city operation.
Because the piping lane is located the underground, cast-in-place piping lane is generally under the inside construction of foundation ditch. The operating space of foundation ditch is less, can't pile up the material in a large number, if the material piles up too much will influence constructor's normal operation, when carrying out piping lane formwork, traditional stay bolt fixed method efficiency of construction is lower, because stay bolt is generally longer, at the inside unable normal operation of foundation ditch, during the construction of piping lane top panel, need set up the support at the template of bottom in addition, prevent that the concrete from dropping, and traditional full hall support occupation space is great, and the efficiency of construction is lower.
In summary, it is very important to find a large-section multi-cabin cast-in-place utility tunnel formwork system which can be spliced quickly and does not occupy a large amount of space.
