Description

Technical Field

[0001] This utility model relates to the field of water flow energy dissipation technology, and in particular to an assembled impact energy dissipation box structure. Background Technology

[0002] Energy dissipation structures are engineering facilities built to eliminate excess kinetic energy from the rapid flow discharged from spillway structures or structures with significant elevation differences, preventing or mitigating the scouring and damage to hydraulic structures and downstream rivers and canals. For small culverts, tunnels, and the outlets of water conveyance and waterproof pipelines, impact energy dissipation boxes are a more economical and practical energy dissipation structure. Traditional impact energy dissipation boxes mostly use cast-in-place concrete structures, which have drawbacks such as complex on-site formwork, long curing periods, and difficulty in adjustment. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an assembled impact energy dissipation box structure that can solve the problems of low construction efficiency and long construction period of traditional impact energy dissipation boxes in cast-in-place concrete structure construction.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] An assembled impact energy dissipation box structure includes a base plate, side plates detachably connected to both sides of the base plate, a back plate detachably connected to the water-facing side of the two side plates, an overflow baffle detachably connected to the backwater side of the two side plates, and an energy dissipation baffle detachably connected to the middle of the two side plates. The impact energy dissipation box structure is a semi-enclosed structure with an open top. The impact energy dissipation box structure has two cavities separated by the energy dissipation baffle inside. The lower part of the energy dissipation baffle has several orifices, and the two cavities are connected through the orifices. A water pipe connection hole is provided in the middle of the back plate. The back plate, base plate, side plates, energy dissipation baffle, and overflow baffle are all prefabricated components.

[0006] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:

[0007] The base plate is anchored to the foundation, and the lower parts of the back plate and the overflow baffle extend beyond the base plate and are embedded in the foundation for anti-slip anchoring.

[0008] The back plate, the bottom plate, the side plate, the energy dissipation baffle, and the overflow baffle are all precast reinforced concrete components, and the corresponding connections are respectively provided with matching tenons and mortises.

[0009] The height of the energy dissipation baffle is located at half the height of the side plate.

[0010] The height of the overflow baffle exceeds the height of the orifice but does not exceed the height of the energy dissipation baffle.

[0011] The height of the water pipe connection hole exceeds the height of the orifice but does not exceed the height of the energy dissipation baffle.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects: the back plate, bottom plate, side plate, energy dissipation baffle, and overflow baffle are all prefabricated and detachable, which significantly improves construction efficiency, greatly reduces construction difficulty, and reduces maintenance and reconstruction costs. It can also be reused in different locations, which is low-cost and more environmentally friendly. The energy dissipation baffle and overflow baffle form a bipolar energy dissipation, which effectively prevents downstream scouring. Attached Figure Description

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote elements with the same or similar functions throughout.

To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] This utility model provides an assembled impact energy dissipation box structure, including a base plate 2, side plates 3 detachably connected to both sides of the base plate 2, a back plate 1 detachably connected to the water-facing side of the two side plates 3, an overflow baffle 5 detachably connected to the water-repellent side of the two side plates 3, and an energy dissipation baffle 4 detachably connected to the middle of the two side plates 3. The impact energy dissipation box structure is a semi-enclosed structure with an open top. The impact energy dissipation box structure has two cavities separated by the energy dissipation baffle 4 inside. The lower part of the energy dissipation baffle 4 has several holes 41, and the two cavities are connected through the holes 41. The middle of the back plate 1 has a water pipe connection hole. The back plate 1, base plate 2, side plates 3, energy dissipation baffle 4, and overflow baffle 5 are all prefabricated components.

[0019] In this embodiment, the lower part of the energy dissipation baffle 4 is provided with two openings 41.

[0020] The water pipe is connected to the water pipe connection hole in the middle of the back plate 1. The water flow first impacts the energy dissipation baffle 4, and then enters the cavity near the downstream through the orifice 41 for underflow energy dissipation, and then overflows over the overflow baffle 5.

[0021] Large stones need to be laid on the downstream side of the overflow baffle 5 to prevent long-term overflow from eroding the river channel.

[0022] The bottom plate 2 is anchored to the foundation, and the lower parts of the back plate 1 and the overflow baffle 5 extend beyond the bottom plate 2 and are embedded in the foundation for anti-slip anchoring.

[0023] Back panel 1, bottom panel 2, side panel 3, energy dissipation baffle 4, and overflow baffle 5 are all precast reinforced concrete components, and the corresponding connections are provided with matching tenons and mortises.

[0024] The height of the energy dissipation baffle 4 is at half the height of the side plate 3.

[0025] The height of the energy dissipation baffle 4 can be adjusted according to the actual situation.

[0026] The height of the overflow baffle 5 exceeds the height of the orifice 41 but does not exceed the height of the energy dissipation baffle 4.

[0027] In this embodiment, the height of the overflow baffle 5 is slightly higher than the height of the orifice 41.

[0028] The height of the water pipe connection hole exceeds the height of the orifice 41 but does not exceed the height of the energy dissipation baffle 4.
