Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a prefabricated assembled box culvert structure. Background Art

[0002] Due to urban development, we often face the need to transform old river channels into the ground, or to transform drainage pipes and ditches. The common construction method is to excavate the foundation pit first, and then cast the box culvert concrete structure on site. The on-site construction speed is slow, the quality cannot be guaranteed, and it is easily affected by the weather. In addition, since on-site construction requires the establishment of formwork support frames and scaffolding, the construction risk is high. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a prefabricated assembled box culvert structure to overcome the deficiencies in the above-mentioned prior art.

[0004] The utility model provides a technical solution to the above-mentioned technical problems as follows: a prefabricated assembled box culvert structure, comprising: bolts and a plurality of porous box culvert structural units arranged in sequence, the porous box culvert structural units comprising: a top plate, a bottom plate, a side wall and a plurality of intermediate partition walls, the top plate and the bottom plate are provided with a plurality of bolt holes penetrating the end faces and surfaces at both ends, the side walls and the intermediate partition walls are provided with a plurality of bolt holes penetrating the end faces and sides at both ends, one end of the bolt is located in the bolt hole of one of the two adjacent porous box culvert structural units, and the other end is located in the bolt hole of the other porous box culvert structural unit, so as to connect the two adjacent porous box culvert structural units.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, a rubber water stop ring is provided between two adjacent porous box culvert structural units.

[0007] Furthermore, the end surface of the porous box culvert structural unit has an annular groove adapted to the rubber water stop ring.

[0008] Furthermore, the surfaces of the top plate and the bottom plate are provided with avoidance grooves at the opening of each bolt hole, and the surfaces of the side walls and the middle partition wall are provided with avoidance grooves at the opening of each bolt hole.

[0009] Furthermore, the porous box culvert structural unit is formed by integrally casting reinforced concrete.

[0010] Furthermore, the porous box culvert structural unit is a straight line segment, an arc segment, or a combination of both.

[0011] The beneficial effects of the utility model are as follows: the prefabricated assembly box culvert technology can speed up the box culvert construction speed, improve the construction quality, reduce the construction risk, and is less affected by the weather. In addition, since the on-site construction requires a large site, a temporary access road needs to be set up, and the prefabricated assembly technology can use the assembled box culvert structure as a temporary road and operation platform, thereby reducing site occupation or reducing temporary land acquisition. It is more advantageous in areas where there are no conditions for setting up temporary access roads. The number of box culvert holes is set according to actual needs. The structure is mainly used for river channel reconstruction, water passage, etc. BRIEF DESCRIPTION OF THE DRAWINGS
