Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage, in particular to a drainage ditch suitable for a wind farm road in a mountainous area. Background Art
[0002] Due to the influence of factors such as climate conditions, topography, geological conditions and mountain seepage, the road engineering of wind farms in the southern mountainous areas has the characteristics of difficult construction, long route distance, large height difference, and great influence of climate conditions. During the construction process, in order to meet the requirements of road drainage, soil and water conservation and large-scale transportation, it is necessary to dig temporary drainage ditches on the side of the road. Due to the long duration of the rainy season, heavy rainfall throughout the year, thick surface humus layer and loose soil in the wind farm area in the southern mountainous areas, it is easy to be washed and eroded by rainwater in places such as roads, slag yards, high and steep slopes and areas with poor geological fluctuations, which can easily cause geological disasters such as landslides, landslides, and soil erosion. In the sections of the wind farm road that are susceptible to rainwater erosion, if the temporary drainage ditch uses an ecological drainage ditch, the bottom of the ditch is uneven because the soil and rocks are difficult to clean, resulting in the inability of the rainwater in the ditch to be discharged in time and water accumulation. The accumulated water seeps down and causes problems such as roadbed instability, slope collapse and soil erosion. If the temporary drainage ditch uses a circular hard plastic pipe drainage ditch, the drainage pipe is incompatible with the ecological ditch in shape and size, and there is a lot of water leakage; the circular drainage pipe has a small inner diameter for water flow, which is easily blocked by debris, making it difficult to clean and maintain, and the length applicability is poor, and it is not easy to install and remove, resulting in limited recycling value. If the temporary drainage ditch uses a concrete drainage ditch, there are problems such as large drainage ditch engineering, high construction cost, slow construction progress, and during the transportation of large equipment or civil construction, large transport vehicles or construction equipment can easily squeeze and damage the concrete drainage ditch, causing the road drainage ditch to need to be reworked, resulting in increased engineering costs.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.
[0025] like Figure 1 As shown, the utility model is a drainage ditch suitable for a mountain wind farm road, comprising a plurality of unit components 1 and a connector 2. The plurality of unit components 1 are arranged parallel to the length direction of a road 4, and two adjacent unit components 1 are connected by the connector 2. Figure 2 As shown, the top of the cross section of the unit component 1 perpendicular to the length direction is a trumpet-shaped opening, and has a first arc segment 11 arranged near the mountain slope 5, a first vertical segment 13 connected to the first arc segment 11, a second arc segment 12 arranged near the road 4, a second vertical segment 14 connected to the second arc segment 12, and a semicircular arc segment 15 for connecting the first vertical segment 13 and the second vertical segment 14. Figure 3 and Figure 4 As shown, the connector 2 is a U-shaped structure, and both ends of the U-shaped structure along the length direction are provided with a mounting groove 21. The first vertical section 13, the semicircular arc section 15 and the second vertical section 14 of the end of the unit component 1 are all snap-fitted with the mounting groove 21, and the sealant 3 is used to seal the seams to prevent leakage. The unit component 1 and the connector 2 are both made of hard plastic material, and the first arc section 11, the first vertical section 13, the semicircular arc section 15, the second vertical section 14 and the second arc section 12 are integrally formed. The drainage ditch of the utility model is made of plastic material, which can be obtained by reprocessing waste plastic products in production and life. The raw materials of the product are widely available, the technical difficulty is small, and therefore the production cost is low. Because the color of the plastic material can be varied, the drainage ditch can also be designed into various colors as needed, and the appearance is more beautiful.
[0026] The drainage ditch of the utility model is applied to the wind farm in the southern mountainous area, and the specific implementation method is as follows:
[0027] (1) Material preparation. According to engineering experience, the natural ecological ditch (i.e. soil ditch) of a wind farm is usually 400mm wide and 400mm deep. In order to match the size of the drainage ditch with the size of the ecological ditch, the wall thickness of the unit component 1 is 5mm, the radius of the semicircular arc segment 15 is 200mm, the length of the first vertical segment 13 and the second vertical segment 14 is 100mm, the radius of the first arc segment 11 and the second arc segment 12 is 100mm, and the total depth of the drainage ditch is also 400mm. The connecting piece 2 is 67mm, the depth of the installation grooves 21 at both ends is 30mm, the distance between the two installation grooves 21 is 7mm, and the wall thickness of the installation groove 21 is 5mm. The first arc segment 11 and the second arc segment 12 can make the drainage ditch more smoothly connected with the road 4 pavement and the slope 5, so that rainwater on the road 4 pavement and rainwater on the road slope 5 can be smoothly merged into the ditch and discharged outside. The quantity of each item of the unit component 1, the connecting piece 2 and the sealant 3 meets the needs.
[0028] (2) Construction preparation. A natural ecological ditch is excavated on the inner side of the wind farm road section that is susceptible to rainwater erosion. The ditch length is the length of the affected area, 400 mm wide and 400 mm deep. The longitudinal slope ratio i of the natural ecological ditch is the designed slope ratio, and the inner edge of the natural ecological ditch is 100 mm away from the toe of the slope.
[0029] (3) Installation of drainage ditch. 1) Apply a layer of 1mm thick adhesive sealant 3 to the length of the two ends of the unit component 1 that need to be inserted into the connecting piece 2. 2) Insert the unit components 1 into the installation groove 21 of the connecting piece 2 respectively to form a 2m long temporary drainage ditch group. After the adhesive sealant 3 solidifies, place the 2m long temporary drainage ditch group into the excavated natural ecological ditch. 3) Connect each temporary drainage ditch group in series to form a complete drainage ditch. The overall length of the drainage ditch is determined according to the length of the road section that is susceptible to rain erosion. 4) Press the two edges and the bottom of the laid drainage ditch to ensure that the temporary drainage ditch is in close contact with the ground as a whole.
[0030] like Figure 1 As shown, in order to make the unit components 1 easy and convenient to connect to each other, the length design of the connecting piece 2 only covers the first vertical section 13, the semicircular arc section 15 and the second vertical section 14 of the unit component 1. There is a 7mm gap between the adjacent first arc sections 11, but this does not affect the function of the drainage ditch to converge and discharge. The drainage ditch size of the utility model is mainly used in parts such as wind power project roads, slag yards and material yards, and its design size can meet the normal rainfall drainage requirements in most parts of the country. If the drainage ditch needs to be used in other projects such as municipal engineering, the design size of the temporary drainage ditch should be adjusted according to the drainage volume and location of the specific project. However, the design concept, appearance and material of the drainage ditch can be used as a reference.
[0031] The utility model is a drainage ditch suitable for the road of a wind farm in a mountainous area, which has beautiful appearance, low cost, simple construction, reliable connection, smooth drainage, good anti-seepage performance, convenient cleaning and maintenance, and high recycling value. According to the construction experience of wind power projects in mountainous areas, if the wind farm road is eroded by water seepage and the lower slope landslides, the engineering repair cost per meter of road is 3 to 5 times the new construction cost, or even more. According to the conventional construction difficulty standard, the cost of new construction of a wind farm in a mountainous area is about 1.2 million per kilometer, while the cost of repairing a wind farm road that has a lower slope landslide due to water seepage in the roadbed is as high as 3.6 million to 6 million per kilometer; therefore, the drainage ditch of the utility model is used in the road engineering of a wind farm in a mountainous area to protect the road from water seepage erosion, indirectly saving a large amount of road engineering repair costs, and having huge economic benefits.
