Description

Technical Field

[0001] The present application relates to the technical field of highway roadbed protection slopes, and specifically discloses a highway roadbed protection slope. Background Art

[0002] Slope protection refers to the general term for various paving and planting done on the slope surface to prevent the slope from being eroded;

[0003] Chinese patent publication number CN214940241U discloses a highway embankment protection slope, which includes a highway embankment and slopes on both sides of the highway embankment. The slopes are provided with partitions, which are grid-like structures and are characterized in that: a plurality of guide rails are laid on the partitions, the length direction of the guide rails is consistent with the inclination direction of the slopes, and brackets are slidably provided on the guide rails along their own length directions, and the brackets are provided with internal hollow cross beams, and nozzles are connected at both ends of the cross beams, and the nozzles face the slope surface of the slopes. A hose is connected on the cross beams, and the end of the hose away from the cross beam is connected to the water source. This application has the effect of reducing the labor intensity of workers when watering ecological slope protection;

[0004] The problem solved by the above patent is: reducing the labor intensity of workers when watering ecological slope protection;

[0005] Back to the ecological irrigation of slope protection, we must first know that for slope protection, there is a certain height and slope. Traditional ecological irrigation of slope protection is manual irrigation, which requires manual climbing or descending. Therefore, most slope protections have stairs built on the slope protection to reduce the labor intensity of workers when watering the ecological slope protection.

[0006] The above patent adopts hose pouring, the hose is exposed and the driving assembly is built beside the roadbed. The above patent is only feasible in theory and cannot be put into practice. Even if the daily maintenance cost of the mechanical mechanism is not considered, the weathering effect of the hose after exposure will lead to the poor effect of the above patent in pouring slope protection.

[0007] To this end, the inventor proposes a slope protection that is switchable and can effectively reduce the labor intensity of workers when watering the ecological slope protection. To this end, the inventor proposes a highway roadbed protection slope. Utility Model Content

[0008] The utility model aims to solve the problem that the ecological irrigation of the slope protection is high in labor intensity for workers when lime is applied to the traditional highway roadbed protection slope in hot seasons.

[0009] In order to achieve the above object, the utility model provides the following basic solutions:

[0010] A highway roadbed protection slope comprises an original foundation, a roadbed arranged on the original foundation, a passable road surface arranged on the roadbed and a guardrail arranged based on the passable road surface, characterized in that it also comprises a protection slope body arranged on both sides of the roadbed, a concrete wall is fixedly connected to the protection slope body, a plurality of vegetation grooves are opened on the concrete wall, a water pipe network with the same shape as the concrete wall is arranged in the concrete wall, water inlets of the water pipe network are opened on the protection slope body on both sides of the passable road surface, and water outlets of the water pipe network are at the bottom of the vegetation grooves.

[0011] The principles and effects of this basic solution are:

[0012] 1. Compared with the prior art, this device has a simple structure and an ingenious design. Through the design of a water pipe network, this device solves the problem of high labor intensity for workers in ecological irrigation of the slope protection during limework in hot seasons in the traditional highway roadbed protection slope, and no longer needs to trim the slope stairs for manual uphill or downhill irrigation.

[0013] 2. Compared with the prior art, compared with the traditional external water pipes, this device embeds the water pipe network inside the concrete wall. This operation can effectively avoid the weathering effect after the hose is exposed, and there is no difficulty in manufacturing. It only needs to determine the number of vegetation troughs and build a water pipe network based on the number of vegetation troughs. After the water pipe network is built, the concrete wall can be protected. After waiting for the concrete wall to solidify, the water pipe network can naturally act on the vegetation trough, and then the vegetation trough can be irrigated.

[0014] 3. Compared with the prior art, this device eliminates the traditional driving components to reduce maintenance costs and construction costs. Based on the principle that the main body of the protective slope has a certain slope and the passable road surface is also passable by humans, the water inlet of the water pipe network is opened on the main body of the protective slope on both sides of the passable road surface, and water is poured into the water inlet. Due to the effect of gravity, water flows to a lower place, and the water outlet of the water pipe network is at the bottom of the vegetation trough, that is, no matter how the water flows, the water will flow out from the bottom of the vegetation trough, thereby watering the vegetation.

[0015] 4. Compared with the prior art, this case has a certain water storage function. Since a water pipe network is designed, and the water inlet of the water pipe network is opened on the main body of the protective slope on both sides of the passable road surface, the water outlet of the water pipe network is at the bottom of the vegetation trough. For the water pipe network, it is similar to a water tank. There will be a part of water in the water pipe network. If watering is needed again, the water flow can quickly reach the vegetation trough.

[0016] Furthermore, the water pipe network is formed by splicing a plurality of water pipes to realize the flow of water, thereby realizing the water flow acting in the vegetation trough.

[0017] Furthermore, the vegetation trough is provided with a soil layer, a gravel layer, a vegetation net and vegetation in sequence from the inside to the outside. The basic structure of the slope vegetation is conducive to soil and water stability and avoids soil and water loss.

[0018] Furthermore, the main body of the protection slope is a right-angled trapezoid, the right-angled surfaces of the main body of the protection slope are arranged on both sides of the roadbed, and the inclined surface of the main body of the protection slope is used to fix the concrete wall, so as to ensure that the concrete wall has a certain slope, which is conducive to the flow of water.

[0019] Furthermore, a support column is provided at the bottom of the water pipe, and the support column is installed on the main body of the protective slope to achieve stable installation of the water pipe. BRIEF DESCRIPTION OF THE DRAWINGS

To realize the flow of water flow, and then realize the water flow acting in the vegetation groove 8, a support column is arranged at the bottom of the water pipe, and the support column is installed on the protection slope body. To realize the stable installation of the water pipe.

[0028] The vegetation trough 8 is provided with a soil layer 11, a gravel layer 12, a vegetation net 13 and vegetation 14 from the inside to the outside. The basic structure of the slope vegetation 14 is conducive to soil and water stability and prevents soil and water loss. The main body of the protection slope is a right-angled trapezoid, and the right-angled surfaces of the main body of the protection slope are arranged on both sides of the roadbed 2. The inclined surface of the main body of the protection slope is used to fix the concrete wall 7. Ensure that the concrete wall 7 has a certain slope, which is conducive to the flow of water.

[0029] Specific implementation process:

[0030] The first step is to pour the roadbed 2 on the basis of the original foundation 1, and harden the road surface on the basis of the roadbed 2 to form a highway;

[0031] In the second step, the main body of the protective slope is cast based on the roadbed 2, the number of vegetation troughs 8 is determined based on the inclined area of ​​the main body of the protective slope, and then the support columns are installed, and the water pipe network 9 is installed on the support columns, as shown in the following figure.
