Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to a prefabricated highway drop structure. Background Technology

[0002] In civil engineering, intercepting ditches are typically installed on the slopes behind buildings and slag heaps, and drainage ditches are installed on walkways to reduce the adverse effects of rainwater and water accumulation on slopes or buildings. After the water from the intercepting and drainage ditches converges, it needs to be treated by slope drops or energy dissipation pools before being discharged into drainage channels with flood control capacity. The construction of slope drops or energy dissipation pools often needs to be adapted to local conditions and may interfere with slope protection work. Determining which highway drop structure can make full use of limited terrain and save construction time is a major challenge for design engineers. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated highway drop structure that is simple in structure, convenient in construction, prefabricated, occupies little space, is easy to assemble and disassemble, and saves construction time.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A prefabricated highway drop manhole structure is connected to a drainage ditch excavated on the highway slope. From bottom to top, it includes a drop manhole cushion layer and a prefabricated manhole body. The prefabricated manhole body is equipped with an energy dissipation pool and a stepped drop sill. The stepped drop sill is symmetrically distributed diagonally. The prefabricated manhole body is provided with inlet slots and outlet slots. It also includes prefabricated inlet / outlet ports, which are respectively connected to the inlet slots and outlet slots.

[0006] Furthermore, the prefabricated inlet / outlet can be rotated.

[0007] Furthermore, both the prefabricated well body and the prefabricated inlet / outlet are prefabricated reinforced concrete structures.

[0008] Furthermore, after the highway slope excavation is completed, the slope at the concave area where water needs to be collected is partially expanded, while the slope on the mountainside is temporarily excavated into a vertical slope.

[0009] Furthermore, the drainage ditch excavated on the highway slope is connected to a prefabricated water inlet.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] This utility model discloses a prefabricated highway drop structure, which is simple in structure, convenient in construction, prefabricated, occupies little space, is easy to assemble and disassemble, and saves construction time. Attached Figure Description

[0015] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a prefabricated highway drop manhole structure is connected to a drainage ditch 4 excavated on the highway slope 0. From bottom to top, it includes a drop manhole cushion layer 1 and a prefabricated manhole body 2, as well as a prefabricated inlet / outlet 3. Both the prefabricated manhole body 2 and the prefabricated inlet / outlet 3 are prefabricated reinforced concrete structures.

[0017] like Figure 2 As shown, the prefabricated well body 2 is equipped with an energy dissipation pool 22 and a stepped drop 21. The stepped drop 21 is symmetrically distributed diagonally. The prefabricated well body 2 is provided with an inlet slot 23 and an outlet slot 24. The prefabricated inlet / outlet 3 can be rotated and is connected to the inlet slot 23 and the outlet slot 24 respectively.

[0018] After the excavation of the highway slope 0 is completed, the slope at the concave area with water collection needs is partially expanded, while the slope on the mountainside is temporarily excavated into a vertical slope. After the foundation expansion is completed, the drop well cushion layer 1 is poured in time, and the precast well body 2 is hoisted onto the top of the drop well cushion layer 1. The drainage ditch 4 excavated from the highway slope 0 is connected to the precast water inlet.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
