Description

Technical Field

[0001] The utility model relates to the field of water conservancy projects, and more specifically, to a water conservancy project slope protection structure. Background Art

[0002] In water conservancy projects, since the slopes are often washed by water or rain, the soil is easily eroded and landslides occur, so water conservancy slope protection structures are often used to prevent them. Existing water conservancy slope protection structures usually include concrete grids laid on the slope surface, and some green plants are usually planted in the concrete grids to reinforce the slope surface. When the flood season comes, ordinary slope protection structures do not have anti-scouring functions. Under the long-term action of water flow, the bottom structure of the concrete grid is prone to collapse and break due to the subsidence or erosion of the underlying soil, thus threatening the stability of the slope protection.

[0003] In order to solve the above problems, in the existing method, a plurality of upwardly extending baffles are usually arranged on the concrete grid to achieve the anti-scouring effect. However, in this method, the baffles cannot be folded and stored. When it is not the flood season and the water level drops, and the scouring of the water flow is small, all the baffles still remain in a vertical upward state. On the one hand, the aesthetics of the slope protection is affected. On the other hand, the baffles will block the green plants, which is not conducive to the healthy growth of green plants.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a slope protection structure for a water conservancy project, which can block the backflow of water flow, thereby reducing the scouring of the slope protection by the water flow, which is beneficial to ensuring the stability of the slope protection, and at the same time can effectively reduce the long-term shading of green plants by the buffer plate.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a water conservancy project slope protection structure, including a slope protection body with a slope surface and a concrete grid laid on the slope surface, the concrete grid including a plurality of transverse concrete ribs arranged at intervals in the transverse direction and a plurality of longitudinal concrete ribs arranged in the longitudinal direction, the cross-sections of the transverse concrete ribs and the longitudinal concrete ribs are both rectangular, a buffer mechanism for water blocking is arranged on the top plane of the transverse concrete rib, the buffer mechanism includes a buffer plate, a hinge seat is fixedly connected to the top upper side of the transverse concrete rib, the upper side of the buffer plate is hinged to the hinge seat through a hinge shaft, the buffer plate can be deflected 0°-180° relative to the top plane of the transverse concrete rib, and a locking assembly that can lock the deflected buffer plate on the hinge seat is also provided on the hinge seat.

[0007] In one of the embodiments, the hinge seat includes two ear ends that are arranged opposite to each other, and the two ear ends are at least partially embedded and fixed inside the transverse concrete rib, and the buffer plate is located between the two ear ends.

[0008] In one of the embodiments, the locking assembly is a bolt, at least one ear end of which is provided with a thread groove extending through the ear end toward the buffer plate, the bolt is threadedly connected to the thread groove, and the bolt can be tightly pressed against the buffer plate.

[0009] In one of the embodiments, a receiving groove is provided on the buffer plate on the opposite side of the top plane of the transverse concrete rib, and an arc-shaped elastic plate with elastic buffering capability is provided in the receiving groove, and the lower side of the arc-shaped elastic plate is fixedly connected to the buffer plate located at the lower side of the receiving groove, and the upper side portion of the arc-shaped elastic plate extends out of the receiving groove.

[0010] In one embodiment, the outer surfaces of the buffer plate and the arc-shaped elastic plate are both provided with a corrosion-resistant coating.

[0011] To sum up, the utility model has the following beneficial effects: the utility model arranges the hinge seat, the buffer plate and the locking assembly, and before the flood season comes, the buffer plate is rotated a certain angle around the hinge axis, so that the buffer plate is kept approximately vertical to the horizontal ground, and is locked and fixed by the locking assembly. The buffer plate can block the backflow of water flow, thereby reducing the scouring of the slope protection by the water flow, which is beneficial to ensure the stability of the slope protection; at the same time, when the flood season is over and the water level drops, part of the buffer plate can be selectively rotated 0°, so that the buffer plate is in contact with the top plane of the transverse concrete rib. In this way, on the one hand, the slope protection structure can be exposed, which is beneficial to improving the aesthetics of the slope protection. On the other hand, the buffer plate will not block the green plants for a long time, which is beneficial to the healthy growth of green plants and further reduces the soil and water loss in the concrete grid.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 3 As shown, an embodiment of the present application provides a water conservancy project slope protection structure, including a slope protection body 1 with a slope surface and a concrete grid laid on the slope surface, the concrete grid including a plurality of transverse concrete ribs 2 arranged at intervals in the transverse direction and a plurality of longitudinal concrete ribs 3 arranged in the longitudinal direction, and the specific laying and fixing method of the concrete grid adopts the existing technology, which will not be repeated in this embodiment. The cross-sections of the transverse concrete ribs 2 and the longitudinal concrete ribs 3 are both rectangular, and a buffer mechanism 4 for water blocking is provided on the top plane of the transverse concrete ribs 2, and the buffer mechanism 4 includes a buffer plate 41, and a hinge seat 5 is fixedly connected to the top upper side of the transverse concrete rib 2, and the upper side of the buffer plate 41 is hinged to the hinge seat 5 through a hinge shaft 6, and the buffer plate 41 can be deflected 0°-180° relative to the top plane of the transverse concrete rib 2, and a locking assembly 7 that can lock the deflected buffer plate 41 on the hinge seat 5 is also provided on the hinge seat 5.

[0018] During the operation of the above-mentioned slope protection structure, before the flood season arrives, the buffer plate 41 is rotated around the hinge shaft 6 by a certain angle so that the buffer plate 41 maintains an approximately vertical state with the horizontal ground, and is locked and fixed by the locking assembly 7. The buffer plate 41 can block the backflow of water, thereby reducing the erosion of the slope protection by the water flow, which is beneficial to ensure the stability of the slope protection; at the same time, when the flood season is over and the water level drops, part of the buffer plate 41 can be selectively rotated by 0° so that the buffer plate 41 is in contact with the top plane of the transverse concrete rib 2. On the one hand, the slope protection structure can be exposed, which is beneficial to improving the aesthetics of the slope protection. On the other hand, the buffer plate 41 will not block the green plants for a long time, which is beneficial to the healthy growth of green plants and further reduces the soil and water loss in the concrete grid.

[0019] In this embodiment, the hinge seat 5 includes two ear ends that are arranged opposite to each other. The two ear ends are at least partially embedded and fixed inside the transverse concrete rib 2, and the buffer plate 41 is located between the two ear ends.

[0020] Specifically, the ear ends can be integrally cast and fixed during the pouring of the concrete grid, or they can be fixed later using expansion screws.

[0021] In this embodiment, the locking assembly 7 is a bolt, at least one ear end of which is provided with a thread groove penetrating toward the buffer plate 41, the bolt is threadedly connected with the thread groove, and the bolt can be tightly pressed against the buffer plate 41. During operation, by tightening the bolt, the bolt and the buffer plate 41 can be tightly pressed against each other, so that the buffer plate 41 can be suspended and fixed on the hinge seat 5 within the range of 0°-180°, which has the advantages of simple structure and convenient and quick operation.

[0022] In this embodiment, a receiving groove 411 is provided on the buffer plate 41 on the opposite side of the top plane of the transverse concrete rib 2, and an arc-shaped elastic plate 42 with elastic buffering ability is provided in the receiving groove 411. The lower side of the arc-shaped elastic plate 42 is fixedly connected to the buffer plate 41 located at the lower side of the receiving groove 411, and the upper side of the arc-shaped elastic plate 42 extends out of the receiving groove 411. The arc-shaped elastic plate 42 is made of a highly elastic metal material. When the water flow impacts, the arc-shaped elastic plate 42 can be elastically retracted toward the receiving groove 411, so as to achieve the effect of buffering and absorbing energy, which is conducive to slowing down the impact force of the water flow and improving the service life of the utility model.

[0023] In this embodiment, the outer surfaces of the buffer plate 41 and the arc-shaped elastic plate 42 are provided with a corrosion-resistant coating, which can specifically be a paint layer. By providing the corrosion-resistant coating, the rust rate of the buffer plate 41 and the arc-shaped elastic plate 42 can be slowed down, which is beneficial to improving the service life.

[0024] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
