Description

Technical Field

[0001] This application relates to the field of road structure technology, and in particular to rural road structures in loess hilly areas with soil and water conservation functions. Background Technology

[0002] Soil and water conservation along rural roads in the Loess hilly and gully region is a key challenge in current small watershed soil and water conservation efforts. The main reasons can be summarized in two aspects: First, the investment standards for small watershed management are too low, making it difficult to achieve the hardening of rural roads and the construction of supporting drainage facilities. Currently, most rural roads are dirt roads, with a few areas using dirt roads covered with gravel. Second, rural roads have a large slope, generally about 15°. Coupled with concentrated rainfall in the region, this easily leads to destructive runoff, which can even cause devastating damage to roads.

[0003] Therefore, there is an urgent need to develop a rural road structure scheme suitable for the Loess Hilly Area, which can ensure soil and water conservation while also being low-cost and easy to construct.

[0004] Therefore, it is necessary to provide rural road structures with soil and water conservation functions in the loess hilly areas to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this application is to provide a rural road structure with soil and water conservation functions in the loess hilly area, so as to solve the problems of the prior art mentioned in the background.

[0006] Based on the above ideas, this application provides the following technical solution: a rural road structure in the loess hilly area with water and soil conservation function, including a foundation, a road surface on the top of the foundation, multiple rain collection pits on both sides of the road surface, the multiple rain collection pits being spaced apart, and an interception plate for filtering garbage being provided inside the multiple rain collection pits on the side near the road surface.

[0007] The bottom of the interceptor plate is equipped with a sand and gravel collection plate, and both ends of the sand and gravel collection plate are equipped with collection mechanisms for collecting sand and gravel.

[0008] As a further aspect of this application: the top of the interceptor plate is provided with multiple filter slots, and a guide plate is fixedly connected to the side of the interceptor plate away from the road surface, the guide plate having an arc-shaped cross-section.

[0009] As a further aspect of this application: the sand and gravel collection plate is configured in a herringbone shape, and a flow groove is provided on the outer side of the sand and gravel collection plate for filtering sand and gravel, and a side plate is fixedly connected to the side of the sand and gravel collection plate away from the rainwater collection pit.

[0010] As a further aspect of this application: the collection mechanism includes a support frame, which is fixedly connected to the side wall of the rainwater collection pit and fixedly connected to one end of the sand and gravel collection plate. A connecting plate is provided inside the support frame, and an elastic element is provided between the connecting plate and the bottom of the support frame. A collection frame is provided on the top of the connecting plate.

[0011] As a further aspect of this application: the collection mechanism further includes a lifting plate, which is fixedly connected to the inside of the collection frame, and a sliding groove is provided on the outer side of the interception plate, through which the lifting plate passes and is slidably connected to the interception plate.

[0012] As a further aspect of this application: the elastic element includes a spring and a telescopic rod, the two ends of the spring and the telescopic rod are respectively fixedly connected to the connecting plate and the support frame, and the spring is sleeved on the outside of the telescopic rod.

[0013] As a further aspect of this application: baffles are provided on both sides of the bottom of the interceptor plate, and the baffles are fixedly connected to the side wall of the rainwater collection pit. The interceptor plate is supported and placed by the baffles and the side plates.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] 1. Rainwater washes down the road surface, carrying away garbage along with the water flow. Therefore, this solution uses interceptor plates to filter the rainwater entering the rain collection pit and filter the garbage. The garbage is then carried by the rainwater to a guide plate on one side of the interceptor plate. In this solution, the rain collection pit is designed in an arc shape, so the garbage is carried away by the rain collection pit to both ends, preventing it from entering the rain collection pit. The filter tank in this solution filters larger pieces of garbage, while small sand and gravel pass through.

[0016] 2. The sand and gravel will roll at both ends of the sand and gravel collection plate. The sand and gravel will roll through the sand and gravel collection plate into the support frame and fall into the collection frame for collection. This avoids the sand and gravel from settling at the bottom of the rainwater collection pit, which would cause the bottom of the rainwater collection pit to rise and require a lot of effort to deal with later.

[0017] 3. After the sand and gravel fall into the collection box, they squeeze the connecting plate at the bottom of the collection box and compress the elastic element. As the collection box falls, it drives the lifting plate at the top of the collection box to descend. When the lifting plate descends to a certain height, the maintenance personnel can judge the amount of sand and gravel collected inside the collection box based on the height of the lifting plate, and thus recycle the sand and gravel.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] like Figures 1 to 4 As shown, the rural road structure in the loess hilly area with soil and water conservation function includes the following embodiments:

[0026] Includes a foundation 1, a road surface 101 on top of the foundation 1, multiple rain collection pits 102 on both sides of the road surface 101, the multiple rain collection pits 102 are spaced apart, and an interception plate 2 for filtering garbage is provided inside the multiple rain collection pits 102 on the side near the road surface 101.

[0027] In practice, rural roads are often damaged by rainwater runoff that accumulates and flows over long distances. Therefore, this plan designs road surface 101 with a slightly higher central section and lower sides, typically with a cross slope of 0.5-1.5%. This aims to allow runoff to flow laterally, reducing its accumulation and shortening its travel distance and time. This facilitates runoff interception and utilization while minimizing road erosion, thus protecting the road. It's worth noting that the longitudinal slope of road surface 101 does not exceed 15°. When the slope exceeds 15°, an "S" shape is adopted, winding upwards. Additionally, this plan includes rainwater collection pits 102 on both sides of road surface 101. These pits intercept runoff, reducing water damage and protecting the road surface from soil erosion.

[0028] It is worth noting that the recommended dimensions for the rainwater collection pit 102 are as follows: the bottom length and width are 1.0 × 0.6m, and the depth is 0.35m; the top width of the earthen embankment is 0.3m, and the slope ratio is 1:0.5-0.75. The construction dimensions of the rainwater collection pit 102 should also be determined in conjunction with the roadside terrain conditions. If the terrain conditions permit, the number of rainwater collection pits 102 can be determined in conjunction with the spacing of roadside afforestation, provided that the runoff interception in the catchment area is met. Generally, the spacing between rainwater collection pits is 2-3m, and they are arranged on both sides of the road. Afforestation can be carried out inside the rainwater collection pit 102 later.

[0029] In this embodiment: a sand and gravel collection plate 3 is provided at the bottom of the interceptor plate 2, and a collection mechanism for collecting sand and gravel is provided at both ends of the sand and gravel collection plate 3.

[0030] The top of the interceptor plate 2 has multiple filter slots, and a guide plate 201 is fixedly connected to the side of the interceptor plate 2 away from the road surface 101. The guide plate 201 has an arc-shaped cross-section.

[0031] In practical implementation, when it rains, rainwater flows down the road surface 101, carrying away the garbage along with the water flow. Therefore, in this solution, an interceptor plate 2 is installed to filter the rainwater entering the rain collection pit 102 and filter the garbage. The garbage is then carried by the rainwater to the guide plate 201 on one side of the interceptor plate 2. In this solution, the rain collection pit 102 is set in an arc shape, and the garbage is carried away by the rain collection pit 102 to both ends, preventing it from entering the interior of the rain collection pit 102. The filter tank in this solution filters larger garbage while allowing smaller sand and gravel to pass through.

[0032] Example 2: The sand and gravel collection plate 3 is set in a herringbone shape, and a flow groove is opened on the outside of the sand and gravel collection plate 3 for filtering sand and gravel. A side plate 301 is fixedly connected to the side of the sand and gravel collection plate 3 away from the rainwater collection pit 102.

[0033] Both sides of the bottom of the interceptor plate 2 are provided with baffles 203. The baffles 203 are fixedly connected to the side wall of the rainwater collection pit 102. The interceptor plate 2 is supported and placed by the baffles 203 and the side plate 301.

[0034] The collection mechanism includes a support frame 4, which is fixedly connected to the side wall of the rainwater collection pit 102 and fixedly connected to one end of the sand and gravel collection plate 3. A connecting plate 401 is provided inside the support frame 4, and an elastic element is provided between the connecting plate 401 and the bottom of the support frame 4. A collection frame 402 is provided on the top of the connecting plate 401.

[0035] In practice, when rainwater washes sand and gravel into the rainwater collection pit 102, the sand and gravel are filtered through the sand and gravel collection plate 3. The sand and gravel collection plate 3 is designed in a herringbone shape, so the sand and gravel will roll at both ends of the sand and gravel collection plate 3. The sand and gravel roll through the sand and gravel collection plate 3 into the support frame 4 and fall into the collection frame 402 for collection. This avoids the sand and gravel from settling at the bottom of the rainwater collection pit 102, which would cause the bottom of the rainwater collection pit 102 to rise and require a lot of effort to deal with later.

[0036] Generally, after each heavy rain, maintenance is required to prevent sand and gravel from becoming stuck or the overall structure from being damaged, thus affecting soil and water conservation. The system implemented in this application effectively prevents soil erosion and damage to the road surface, and effectively collects rainfall. Rainwater is stored in the collection pit 102 and used to irrigate trees, ensuring stable growth of the greenery. When the trees reach a certain age, their root systems will further enhance soil and water conservation by fixing the soil.

[0037] In this embodiment, the collection mechanism also includes a lifting plate 403, which is fixedly connected to the inside of the collection frame 402, and a sliding groove 202 is provided on the outside of the interception plate 2. The lifting plate 403 passes through the sliding groove 202 and is slidably connected to the interception plate 2.

[0038] The elastic element includes a spring 405 and a telescopic rod 404. The two ends of the spring 405 and the telescopic rod 404 are fixedly connected to the connecting plate 401 and the support frame 4, respectively, and the spring 405 is sleeved on the outside of the telescopic rod 404.

[0039] In practice, when sand and gravel fall into the collection frame 402, the connecting plate 401 at the bottom of the collection frame 402 is squeezed, and the elastic element is compressed. As the collection frame 402 falls, the lifting plate 403 at the top of the collection frame 402 is lowered. When the lifting plate 403 falls to a certain height, the maintenance personnel can judge the amount of sand and gravel collected inside the collection frame 402 based on the height of the lifting plate 403, and then recycle the sand and gravel. When recycling, the personnel lift the intercepting plate 2. At this time, the personnel lift the collection frame 402 by holding the lifting plate 403, and then take out the sand and gravel. At the same time, the connecting plate 401 in this solution blocks the sand and gravel from rolling between the connecting plate 401 and the bottom of the support frame 4, and protects the telescopic rod 404 and the spring 405.
