Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and specifically relates to an arched river slope protection structure. Background Technique

[0002] In water conservancy projects, in order to prevent soil erosion on the slope, an arched framework is usually covered on the slope surface to play a role in protecting and strengthening the slope body. However, in the arched slope protection structure, the arch ring needs to bear the soil pressure from the slope body. In addition, it also needs to resist external loads including rain erosion and wind. Without sufficient reinforcement measures, the arch ring will surely deform, and even cracks and fractures will occur, resulting in the instability of the slope protection structure. In this way, the slope body will collapse, threatening the surrounding buildings, roads and personnel safety.

[0003] Therefore, in order to solve the defect that the lack of reinforcement structure of the arch ring leads to the instability of the slope protection structure, it is very necessary to propose an arched river slope protection structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide an arched river slope protection structure. By supporting a herringbone strut beam in the arch ring, the bearing capacity of the arch ring is effectively enhanced. And both ends of the herringbone strut beam are welded to the inner wall of the arched framework through reinforcing ribs, further improving the stability of the entire arched framework structure, enabling the arch ring to better resist external loads and preventing the arch ring from deforming, so as to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An arched river slope protection structure includes a slope body. Climbing ladders are symmetrically arranged at both ends of the slope body. The slope surface of the slope body is distributed in a stepped manner, and is successively divided into a first slope surface, a second slope surface and a third slope surface from top to bottom. Slope platforms are provided between the first slope surface and the second slope surface, between the second slope surface and the third slope surface, and at the slope foot.

[0007] The first slope surface, the second slope surface and the third slope surface are all reinforced by an arched framework. The arched framework includes a first arch ring and a second arch ring arranged up and down. Herringbone strut beams are supported in both the first arch ring and the second arch ring. Both ends of the herringbone strut beam are welded to the inner wall of the arched framework through reinforcing ribs.

[0008] Preferably, wave piles are installed on the slope platform.

[0009] Preferably, a retaining wall is installed at the slope foot, and the retaining wall is reinforced by anti-slip piles.

[0010] Preferably, the slopes of the first slope surface, the second slope surface and the third slope surface are all 45°.

[0011] Preferably, a water retaining edge is provided at the bottom of the first arch ring, and the water retaining edge is arc-shaped.

[0012] Preferably, a fixing net is laid on the soil surface inside the arch-shaped framework of the first slope surface, the second slope surface and the third slope surface.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In this arch-shaped river slope protection structure, through the arrangement of the double-layer arch ring and the herringbone strut beam, the bearing capacity of the arch ring is effectively enhanced. The herringbone strut beam can share the pressure from the slope soil borne by the arch ring and disperse the pressure in all directions, reducing the situation of excessive local stress on the arch ring. At the same time, through the arrangement of the reinforcing ribs, the structural stability of the entire arch-shaped framework is further improved, the ability of the arch-shaped framework to resist external loads is enhanced, and the deformation of the arch ring is prevented.

[0015] 2. In this arch-shaped river slope protection structure, by arranging the stepped slopes, the water flow velocity on the slope can be effectively slowed down. When rainwater flows down along the slope, the stepped slope surface and the slope platform will block the water flow multiple times, reducing the scouring force of the water flow on the slope surface, thereby reducing the risk of soil erosion.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer toFigure 1 - Figure 2 An arched river slope protection structure includes a slope body 1. Climbing ladders 2 are symmetrically arranged at both ends of the slope body 1. The slope surface of the slope body 1 is distributed in a stepped manner and is successively divided into a first slope surface 11, a second slope surface 12, and a third slope surface 13 from top to bottom. The slopes of the first slope surface 11, the second slope surface 12, and the third slope surface 13 are all 45°. Slope platforms 14 are provided between the first slope surface 11 and the second slope surface 12, between the second slope surface 12 and the third slope surface 13, and at the slope foot.

[0022] Among them, the setting of the climbing ladders 2 provides a convenient passage for construction personnel to maintain and repair the slope body 1 in the later stage;

[0023] The slope surface is set in a stepped manner, and slope platforms 14 are provided between the slope surfaces and at the slope foot. This structural design breaks the traditional single-slope surface structure, helps to disperse the overall sliding force of the slope body 1, and at the same time has better stability and anti-scouring ability. The slope platform 14 can buffer and divert rainwater, reduce the direct scouring of rainwater on the slope surface soil, protect the integrity of the slope surface soil, and thus extend the service life of the slope protection device.

[0024] Please refer to Figure 1 - Figure 2 , wave piles 141 are installed on the slope platform 14.

[0025] Among them, the setting of the wave piles 141 enhances the stability of the slope platform 14 and the entire slope body 1, can effectively resist the lateral pressure generated by the soil of the slope body 1, and at the same time can prevent the settlement of the slope platform 14.

[0026] Please refer to Figure 1 - Figure 2 , a retaining wall 4 is installed at the slope foot, and the retaining wall 4 is reinforced by anti-slip piles 5.

[0027] Among them, the setting of the retaining wall 4 can prevent the slope body 1 from collapsing, prevent the soil of the slope body 1 from sliding out of the slope foot. At the same time, a large amount of rainwater will converge at the slope foot and generate a scouring force during the rainy season. The retaining wall 4 can block the erosion of rainwater on the slope foot soil and maintain the structural integrity of the slope foot soil, providing a solid foundation for the stability of the slope body 1;

[0028] The anti-slip piles 5 play a role in reinforcing the retaining wall 4, making the retaining wall 4 more firmly connected to the soil below the slope foot, preventing the retaining wall 4 from tilting or shifting, and at the same time improving the overall bearing capacity of the slope foot.

[0029] To solve the technical problem of how to reinforce the arch ring, please refer to Figure 3 , the present embodiment provides the following technical solutions:

[0030] The first slope surface 11, the second slope surface 12, and the third slope surface 13 are all reinforced by an arch-shaped framework 3. The arch-shaped framework 3 includes a first arch ring 31 and a second arch ring 32 arranged vertically. Inside the first arch ring 31 and the second arch ring 32, there are herringbone support beams 33 supported. Both ends of the herringbone support beams 33 are welded to the inner wall of the arch-shaped framework 3 through reinforcing ribs 34.

[0031] Specifically, in the arch-shaped framework 3, herringbone support beams 33 are arranged inside both the first arch ring 31 and the second arch ring 32 to support the top part of the arch. When the soil on the slope applies pressure to the arch ring under the action of gravity, the herringbone support beams 33 can share the pressure borne by the top of the arch, preventing the top of the arch from deforming due to excessive pressure. Moreover, the arrangement of the reinforcing ribs 34 further reinforces the arch ring. The reinforcing ribs 34 are like a bond that tightly binds the herringbone support beams 33 and the arch-shaped framework 3, capable of effectively transmitting force, so that the force on the entire arch-shaped framework 3 is more evenly distributed, and at the same time, the displacement of the herringbone support beams 33 is restricted.

[0032] Among them, a water retaining edge 311 is provided at the bottom of the first arch ring 31, and the water retaining edge 311 is arc-shaped.

[0033] It should be noted that the setting of the water retaining edge 311 can effectively intercept rainwater, reduce the direct scouring force of rainwater on the slope soil, control the flow velocity and flow rate of rainwater on the slope, keep the soil particles in a relatively stable state, thereby protecting the integrity of the slope soil and maintaining the stability of the slope.

[0034] Among them, a fixing net 35 is laid on the soil surface inside the first slope surface 11, the second slope surface 12, and the third slope surface 13 within the arch-shaped framework 3.

[0035] It should be noted that the setting of the fixing net 35 is used to fix the soil, prevent the soil from shifting and flowing away when being scoured by rainwater, and at the same time can enhance the overall stability of the soil and improve the ability of the slope soil to resist deformation and sliding.
