Description

Technical Field

[0001] This disclosure relates to the field of road technology, and more specifically, to a road structure for an onshore wind farm. Background Technology

[0002] (1) Commonly used drainage ditches for wind farm roads mainly use dry-laid rubble, mortar-laid rubble, cement mortar bricks, concrete and reinforced concrete, etc. Some of them can be sourced locally, but in most cases they need to be purchased from building materials markets, which increases construction costs and overall investment in wind power projects.

[0003] (2) The structure is complex and the construction process requires formwork, concrete curing and other work, which requires a large number of templates, increases the construction period and does not meet the construction period requirements of onshore wind farms.

[0004] (3) The construction process is complex and requires a high level of technical skills from the construction personnel, which increases the risk of quality problems in the construction process.

[0005] (4) Wind farms that use traditional road drainage ditches often experience problems such as drainage ditch blockage and damage, which leads to large-scale damage to the wind farm roads, affecting the normal operation of the wind farm, and the repair costs are high. Summary of the Invention

[0034] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0035] Reference Figures 1 to 3As shown, this disclosure provides an onshore wind farm road structure, which includes a roadbed 1, a road surface body 2, a drainage ditch 4, and a slope 5. The roadbed 1 includes a first roadbed section 11 and a second roadbed section 12 connected to each other. The road surface body 2 is disposed above the first roadbed section 11. One side of the second roadbed section 12 is connected to the first roadbed section 11 and the road surface body 2, and the other side is connected to the drainage ditch 4. The side of the drainage ditch 4 away from the second roadbed section 12 is connected to the slope 5, and the cross-sectional structure of the drainage ditch 4 is V-shaped.

[0036] In the above technical solution, the first roadbed section 11 of the roadbed 1 provides an installation foundation for the road surface body 2, and the second roadbed section 12 is equivalent to a road shoulder, which allows water on the road surface body 2 to be discharged into the drainage ditch 4. The drainage ditch 4 has a V-shaped cross-section. After the water on the road surface body 2 is discharged into the drainage ditch 4, the V-shaped drainage ditch 4 can effectively reduce the blockage and ensure smooth drainage.

[0037] In one implementation, reference Figure 2 As shown, the drainage ditch 4 includes a drainage ditch body 41, a first connecting part 42, and a second connecting part 43. The first connecting part 42 and the second connecting part 43 are respectively connected to both ends of the drainage ditch body 41. The first connecting part 42 is connected to the second roadbed section 12, and the second connecting part 43 is connected to the slope 5. By providing the first connecting part 42, the connection between the drainage ditch 4 and the roadbed 1 can be better realized. By providing the second connecting part 43, the connection between the drainage ditch 4 and the slope 5 can be better realized. The first connecting part 42 and the third connecting part 43 can be constructed in any suitable shape and structure, and this disclosure does not limit them.

[0038] Optionally, refer to Figure 3 As shown, the drainage ditch 4 includes multiple drainage ditch segments 40, which are spliced ​​together in pairs. Any three adjacent drainage ditch segments 40 include a first drainage ditch segment 401, a second drainage ditch segment 402, and a third drainage ditch segment 403. An expansion joint 404 is provided between the first drainage ditch segment 401 and the second drainage ditch segment 402, and the expansion joint 404 is filled with polyethylene paste. A plate joint 405 is provided between the second drainage ditch segment 402 and the third drainage ditch segment 403, and the plate joint 405 is filled with C20 concrete with an expansion agent content of 10%. By splicing multiple drainage ditch segments 40, the construction method is simpler. The addition of polyethylene paste to the expansion joint 404 and C20 concrete with an expansion agent content of 10% to the plate joint 405 not only improves the connection stability and sealing of each drainage ditch segment 40, but also effectively extends the service life of the drainage ditch 4.

[0039] In other embodiments, the thickness of the drainage ditch body 41 is 50 mm, the width of the expansion joint 404 is between 25 mm and 30 mm, the thickness of the polyethylene paste is 50 mm, the width of the board joint 405 is between 25 mm and 30 mm, and the thickness of the C20 concrete is 50 mm. However, this disclosure does not limit the above dimensions, and they can be set according to actual needs.

[0040] Optionally, the drainage ditch section 40 can be cast using C20 concrete through a mold, but this disclosure does not limit the forming method of the drainage ditch section 40.

[0041] Reference Figure 2 As shown, the outer surfaces of the first connecting portion 42 and the second connecting portion 43 each include a planar segment 421, a first inclined segment 422, and a second inclined segment 423 connected sequentially to each other. One end of the planar segment 421 is connected to the inner surface of the drainage ditch body 41, and the other end of the planar segment 421 is connected to the first inclined segment 422. The second inclined segment 423 connects the first inclined segment 422 and the outer surface of the drainage ditch body 41, and the included angle between the second inclined segment 423 and the outer surface of the drainage ditch body 41 is 150°. The arrangement of the planar segment 421 allows for better parallel arrangement with the second roadbed segment 12, and the arrangement of the first inclined segment 422 and the second inclined segment 423 allows for better fit with the roadbed 1, improving sealing performance.

[0042] Optionally, the width of the first connecting portion 42 and the second connecting portion 43 is 100 mm, the width of the drainage ditch body 41 is 693 mm, and the depth of the drainage ditch 4 is 600 mm. However, this disclosure does not limit the above dimensions.

[0043] Optionally, the expansion angle of the drainage ditch 4 is between 55° and 65°, which facilitates the downward sliding of debris and reduces the adhesion of debris to the inner wall of the drainage ditch 4.

[0044] In one implementation, reference Figure 1 As shown, the upper surface of the road surface body 2 and the upper surface of the second roadbed section 12 are connected to form a first surface 20. In the direction that gradually approaches the drainage ditch 4, the first surface 20 extends downward at an angle relative to the horizontal plane. The inclined arrangement of the first surface 20 facilitates the flow of water into the drainage ditch 4.

[0045] Optionally, the first roadbed section 11 and the second roadbed section 12 are integrally formed to facilitate construction.

[0046] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0048] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
