Description

A prefabricated part for urban underground passage

technical field

The utility model relates to a prefabricated part for urban underground passages.

Background technique

With the progress of society, the rapid progress of urbanization, the popularization and application of new technologies, there are more and more various underground pipe networks laid in cities, which are more and more complex, and the available space is less and less. Cables, optical cables, cable, telephone, natural gas, heating, water supply, drainage and other systems are relatively independent, and manhole covers are scattered all over the place, causing inconvenience to pedestrians and vehicles, which is not conducive to construction or maintenance. The construction cost is high, and the manpower and material resources are seriously consumed.

Utility model content

Aiming at the defects existing in the prior art, the problem to be solved by the utility model is to provide a prefabricated part for urban underground passages which is convenient for centralized construction of urban underground passages, rational layout, and convenient pipeline maintenance.

The technical scheme that the utility model solves its technical problem adopts is:

A prefabricated part for an urban underground passage, which includes a top plate, two side plates, a positioning support structure located between the two side plates, and a sump at the bottom; the top plate is an upwardly convex arc, and the top plate An inlet hole is arranged on the top; the two side plates are respectively connected to the opposite ends of the top plate and parallel to the direction of the underground passage, an opening for the pipeline to pass is set on the side plate, and a sealing rubber pad is set on the upper end surface of the side plate; The positioning support structure is arranged between the two side plates, the positioning support structure is a bracket and/or a hook, and the hook is fixedly connected to the side plate; the side plate and the top plate are connected by a notch and a positioning plug-in .

As a further improvement, the top board and/or side boards are provided with steel bar support.

The beneficial effects of the utility model are: the prefabricated parts are combined, and the top plate and the side plate are connected by a stopper and a positioning plug-in, so as to ensure accurate installation and positioning and avoid misalignment of the position. Guarantee product quality, facilitate product transportation, and reduce the cost of use; the joint surface of the prefabricated part is sealed with a sealing rubber pad to solve the leakage problem; the interior of the prefabricated part is made of high-strength steel bars to ensure the strength of the prefabricated part and improve the safety of underground use ;The positioning support structure positions and supports the pipes and lines, realizes three-dimensional laying of pipes and cables, and makes full use of the space to facilitate the installation and construction of cable pipes; the arc-shaped design of the top cover has high compressive strength and long service life; On the plate, the pipeline perpendicular to the side plate surface passes through; the bottom is provided with a water collection groove, which is convenient for removing accumulated water and dirt; the cavity of the utility model can be walked by people, so it is also suitable for civil air defense projects and can be used for combat readiness Air defense engineering facilities.

The utility model can realize unified planning and reasonable layout of various underground pipe networks in cities, save underground resources, facilitate centralized construction, reduce overall investment, reduce comprehensive costs, avoid multiple construction excavations on the road surface, and greatly facilitate management and maintenance. maintain.
