Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roads, in particular to a pavement structure of a mining transportation road. Background Art
[0002] Most mining companies are located in mountainous areas with inconvenient transportation. Their transportation roads are often simple soil roads. Although mining cars can also run, their resistance to natural factors and carrying capacity are very poor. Dust flies when the weather is clear, and rainwater accumulates on the road surface on rainy days, making the road muddy. Most mining vehicles are heavy-loaded vehicles, which have high requirements for carrying capacity. Therefore, the road surface is often bumpy after rain, causing vehicles to bump and slip, or even unable to pass, and causing serious vehicle damage. After paving the road surface, the road conditions can be improved, allowing vehicles to pass at a certain speed, smoothly and safely.
[0003] In addition, due to poor drainage, the current mine transportation roads are prone to water accumulation during the rainy season, which not only causes the roads to be slippery, but is also easily damaged by rainwater accumulation, thus affecting driving safety.
[0004] In view of this situation, it is urgent to design a road pavement structure suitable for heavy-duty mining vehicles to improve driving conditions and ensure driving safety. Summary of the invention

[0007] The utility model discloses a road pavement structure suitable for heavy-loaded mining vehicles, which is composed of a crushed stone pavement, a drainage blind ditch and an anti-seepage layer. The crushed stone pavement is paved on a foundation trench excavated from an original earth road, the bottom of the foundation trench is an "inverted V-shaped" slope with a high middle and low sides, and the slope is used to guide water to the drainage blind ditches on both sides. The drainage blind ditches are built on both sides of the foundation trench. The anti-seepage layer is paved on the bottom surface of the foundation trench and the drainage blind ditches on both sides of the foundation trench, and the anti-seepage layer is used to isolate water and prevent rainwater from seeping into the roadbed. A drainage pipe is laid in the drainage blind ditch and crushed stones are buried and compacted.
[0008] Furthermore, the slope of the "inverted V-shaped" slope is preferably in the range of 5° to 8°.
[0009] Furthermore, a plurality of water filtering holes are evenly arranged on the wall of the drainage pipe to facilitate rapid and timely drainage.
[0010] Furthermore, the wall of the drainage pipe is wrapped with geotextile and fastened with galvanized iron wire.
[0011] Furthermore, the diameter Φ of the water filter hole is 8-12 mm, preferably 10 mm.
[0012] In actual applications, the drainage pipe is made of high-quality PE pipe; the anti-seepage layer is made of highly elastic waterproof material.
[0013] The utility model has the following positive effects after adopting the above technical scheme:
[0014] (1) The utility model sets a gravel road surface, which can improve the bearing capacity and anti-skid ability of the original transportation road, meet the driving requirements of heavy-duty vehicles in mines, and reduce dust and improve the mine environment;

[0020] In order to better describe the utility model, the following is a further detailed description of a road pavement structure suitable for heavy-duty mining vehicles in accordance with the utility model in combination with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other implementation channels obtained by ordinary technicians in this field without creative work are all within the scope of protection of the utility model.
[0021] In addition, it should be understood that for the sake of ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. For example, the thickness or width of some parts may be larger than that of other parts.
[0022] Depend on Figure 1 The utility model is a transverse cross-sectional view of a road pavement structure suitable for heavy-duty mining vehicles. Figure 2 It can be seen that the utility model is a road pavement structure suitable for heavy-duty mining vehicles to travel, which is composed of a crushed stone pavement 2, a drainage blind ditch 3, and an impermeable layer 5; the crushed stone pavement 2 is paved on the foundation trench excavated from the original earth road 1, and the bottom of the foundation trench is an "inverted V-shaped" slope with a high middle and low sides, and the slope is 5° to 8°; the drainage blind ditch 3 is built on both sides of the foundation trench; the impermeable layer 5 is laid on the bottom surface of the foundation trench and the drainage blind ditches 3 on both sides of the foundation trench; a drainage pipe 4 is laid in the drainage blind ditch 3 and filled with crushed stone for compaction, and a plurality of water filtering holes 8 are evenly arranged on the pipe wall of the drainage pipe 4; in the embodiment, the aperture Φ of the water filtering hole 8 is 10 mm, and the pipe wall of the drainage pipe 4 is wrapped with a geotextile 6 and fastened with a galvanized iron wire 9.
[0023] The utility model is a road pavement structure suitable for heavy-duty mining vehicles. During the construction process, a foundation trench is first excavated on the original earth road 1, and the bottom of the trench forms an "inverted V-shaped" slope with a high middle and low sides, with a slope of 5° to 8°. Then, an anti-seepage layer 5 is laid at the bottom of the foundation trench and in the trenches on both sides. The anti-seepage layer 5 is a highly elastic waterproof material. After the anti-seepage layer 5 is laid, gravel is filled and a drainage pipe 4 is laid and compacted. The gravel used should have the characteristics of high hardness, high strength and good wear resistance. Pebbles, granite, marble, limestone, etc. can be selected. Rainwater collected on the gravel road surface 2 can flow into the drainage blind ditch 3 along the bottom of the trench and be discharged through the drainage pipe 4 buried in the drainage blind ditch 3. The drainage pipe 4 adopts a high-quality PE pipe, and the pipe wall is evenly provided with water filter holes 8 with a hole diameter of 10 mm. The pipe wall is covered with geotextile 7 and tied with galvanized iron wire 9.
[0024] Compared with traditional soil roads, the gravel road surface 2 can effectively improve the road's bearing capacity and anti-skid ability, reduce dust, and beautify the mine environment while ensuring driving safety and efficiency; the drainage blind ditch 3 can timely discharge rainwater that seeps from the gravel road surface 2, and the anti-seepage layer 5 blocks the rainwater infiltration channel, which can effectively prevent the softening effect of rainwater on the roadbed. At the same time, the drainage pipe 4 can effectively collect rainwater and discharge it in a centralized manner, and can be used in conjunction with the rainwater collection pool as mine water to reduce water pressure.
