Description

Technical Field

[0001] The invention relates to the technical field of highway slope protection, and in particular to a highway slope protection drainage structure and a construction method thereof. Background Art

[0002] Highway slope protection is an important measure to ensure road safety and stability. Its main purpose is to prevent slope landslides, collapses and other natural disasters from affecting highways. The following are some common highway slope protection methods:

[0003] By planting lawns, shrubs or trees, using the roots of plants to fix the soil, reducing soil erosion, building an effective drainage system, and preventing rainwater and groundwater from eroding the slopes, common measures include ditches, seepage wells and drainage pipes. In areas where the slopes are steeper or the soil is looser, retaining walls can be built to increase the stability of the slopes. Geotextiles or geonets can be used to reinforce the slopes to prevent soil erosion and enhance the slope's anti-slip ability. Regularly inspect and maintain the slopes, clean drainage facilities in a timely manner, and repair damaged protective measures. Through the comprehensive use of these protective measures, the stability of highway slopes can be effectively improved and traffic safety can be guaranteed.

[0004] For example, the roadbed rock slope stability reinforcement structure and method disclosed in publication number CN 119145434 A, although the anti-slip handle is used to drive the rotating shaft mechanism to rotate, thereby facilitating the storage of the protective net, so that the protective net can be quickly stored when the rock slope body is being trimmed. When using the protective net, the protective net can be directly pulled out, thereby reducing the difficulty of installing the protective net.

[0005] The above design still has defects. The protective effect on the slope is relatively simple and cannot generate more utilization value for the slope. In addition, in actual application, the protective net on the slope fits the surface of the rock slope body to achieve more stable protection of the rock slope body. However, when larger gravel slides down, it cannot block the sliding gravel, and the larger area of ​​the slope will also be wasted, which will reduce the use effect. Therefore, the above problems need to be solved. Summary of the invention

[0011] Furthermore, the construction method of the slope protection drainage structure of the highway specifically includes the following steps:

[0012] S1: Conduct a field survey of the slope rock layer, and pre-embed the concrete base according to the position of the slope rock layer, and support it according to the specific shape of the concrete layer, pre-embed the suction pipe, the first connecting pipe and the drainage pipe, and then pour concrete.

[0016] In the present invention, when in use, rainwater falls on the surface of the concrete layer.

When the rainwater is stored in the two water collecting grooves, it can be driven by the suction pump controlled by the control cabinet when needed, so that the water inside the two water collecting grooves is absorbed through the two first connecting pipes and the first connecting pipe, and then through the drainage pipe and the multiple second connecting pipes, the rainwater is sprayed on the inside of the multiple soil layers through the multiple nozzles, so that the green plants planted on the surface of the soil layer can be watered. At the same time, the green plants planted on the surface of the soil layer will produce a certain buffer for the sliding gravel, thereby effectively reducing the sliding phenomenon at any time.

[0017] When gravel slides through the surface of the concrete layer, the two protective plates can block the gravel, which can effectively block the impact force of the falling gravel. At the same time, under the action of the torsion springs arranged on the surface of the protective plates, the gravel can pass through the surfaces of the two protective plates and slide to the surface of the leaking plate.

[0018] The battery inside the control cabinet can be replenished by the solar panel, so as to facilitate the driving of the suction pump, thereby saving the energy required for irrigation and making the slope more valuable. BRIEF DESCRIPTION OF THE DRAWINGS

During the concrete pouring process, the fixing rod (23) was installed; S2: The soil layer (6) inside the built-in groove (21) is filled with grass and the grass is planted inside the soil layer (6). The protective net (3) is then installed on the surface of the built-in groove (21), thereby protecting the soil layer (6) and preventing soil loss. Water can be precipitated through the soil layer (6) inside the multiple built-in grooves (21) and flow into the two water collection grooves (24) through the multiple water flow grooves (26). The control system inside the control cabinet (5) can drive the suction pump (51) so that the water inside the water flow groove (26) can irrigate the soil layer (6) inside the multiple built-in grooves (21); S3: A support column (211) is installed on the surface of the concrete layer (2), and a protective plate (43) and a solar panel (4) are installed. By setting a torsion spring (46), a certain angle is formed between the protective plate (43) and the solar panel (4), so as to prevent the falling rocks from sliding down with a large impact force, causing the falling rocks to impact on the road and thus affecting the driving on the road; S4: Solar energy can be converted into electrical energy through the solar panel (4), and the electrical energy is stored in a battery arranged inside the control cabinet (5) through a wire, which can increase the energy for the operation of the suction pump (51).
