Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of culverts, and specifically relates to a new type of prefabricated and assembled culvert. Background Technique
[0002] Culverts have been relatively widely used in aspects such as water conservancy projects, municipal engineering, and traffic engineering. They are mainly used in projects such as flood discharge channels, urban sewage pipelines, underground pedestrian passages, and underground motor vehicle tunnels. Currently, the construction of culverts generally adopts the method of in-situ casting. In the actual application process, not only concrete molds need to be arranged on-site first, but also waiting for the concrete to solidify after pouring, resulting in a relatively long construction period. Most of the construction time is spent on the construction of the box culvert. The in-situ casting time and curing time of the culvert are relatively long, which greatly affects the construction progress of the project. At the same time, it also prolongs the project duration and wastes a certain amount of human and material resources.
[0003] Although the current precast culverts can speed up the construction progress, in the actual use process, there are some inconveniences with the overall square culverts. Such culverts are not convenient for transportation, bringing quite a challenge to transportation. Therefore, a new type of prefabricated and assembled culvert is needed to improve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a new type of prefabricated and assembled culvert to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution:
[0006] A new type of prefabricated and assembled culvert includes an upper precast culvert slab, a first side precast culvert slab, a second side precast culvert slab, and a lower precast culvert slab. Reinforcing blocks are fixedly arranged on both sides of the surfaces of the upper precast culvert slab and the lower precast culvert slab. Docking blocks two are fixedly arranged on both sides of the surface of the upper precast culvert slab. One ends of the first side precast culvert slab and the second side precast culvert slab are respectively provided with docking grooves one adapted to the docking blocks two. Docking grooves two are fixedly arranged on both sides of the surface of the lower precast culvert slab, and one ends of the first side precast culvert slab and the second side precast culvert slab are respectively provided with docking blocks one adapted to the docking grooves two.

[0008] As a preferred scheme of the utility model, a bolt is arranged inside the installation hole, and the bolt is in threaded connection with nuts on the sides of the first side precast culvert slab and the second side precast culvert slab.
[0009] As a preferred solution of the present utility model, grouting grooves corresponding thereto are provided inside the upper precast box culvert slab, the first side precast box culvert slab, the second side precast box culvert slab, and the lower precast box culvert slab.
[0010] As a preferred solution of the present utility model, the first side precast box culvert slab and the second side precast box culvert slab have the same structure.
[0011] As a preferred solution of the present utility model, the first docking groove, the first docking block, the second docking block, and the second docking groove are all trapezoidally arranged.
