Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example one
The embodiment discloses a box-shaped structure 1 for earth covering and backfilling of subway and municipal works, as shown in fig. 1, comprising: more than one box 11, a plurality of brackets 12 for erecting pipelines, and a plurality of connecting parts 13 for connecting with the brackets 12; the support 12 is arranged on the inner wall of the box body 11 through the connecting part 13, the support 12 is provided with a containing position 121 for placing the pipeline 2, the box body 11 is partially buried in soil above the top plate of the subway station 3 to be used as backfill between the subway station 3 and municipal works, when the box body 11 is prefabricated, the box body 11 can be an independent box body 11, and a plurality of box bodies 11 can be connected into a whole, so that the process of site construction is reduced.
According to the embodiment, the plurality of boxes 1 replace the traditional earthing backfill, so that the earthing thickness of the top plate of the subway station 3 is reduced, further reinforcement on the station structure is not needed, the station structure is safer, the construction cost is reduced, and the investment is saved; meanwhile, a support 12 for erecting pipelines is further arranged in the box body 11, and the requirement of municipal pipeline laying is met.
In the above embodiment, the side wall of the box body 11 is provided with the opening for accommodating the pipeline 2 to pass through, when the box body 11 is prefabricated, the opening can be reserved firstly, and the position and the number of the opening can be determined by combining with the actual construction site.
In the above embodiment, the support 12 is a steel support, which can provide sufficient support for the pipeline.
In the above embodiment, the connecting member 13 is an anchor bolt embedded in the inner wall of the box 11, and the bracket 12 is a reinforced concrete cantilever beam fixed to the inner wall of the box 11 by the anchor bolt.
In the above embodiment, the box body 11 is a reinforced concrete box body, and the manufacturing cost is relatively low, so that the strength of the box body 11 is higher.
