Description

Technical Field

[0001] The invention relates to the field of road reconstruction, and in particular to a ground paving device at a saddle point of a mountain road used in a new energy wind farm. Background Art

[0002] In recent years, with the vigorous development of new energy, the limiting factors of various mountainous terrains have gradually emerged, especially in the saddles of steep mountainous terrains. Since the length of the transport vehicles of new energy wind power projects is about 25 to 28 meters, the hub width is about 5 meters, and the maximum load weight exceeds 100 tons, higher requirements are put forward for the design of new energy wind farm roads. According to statistics, some wind power projects have cancelled the construction of roads because some machine positions are narrow and steep at the saddle of the mountain, which not only affects the calculation of wind resources for the entire project, but also affects the guarantee of power generation. At present, the most common way to deal with this kind of terrain is to build retaining walls. However, when facing higher and steeper terrain, the amount of engineering work of the retaining walls is very large, which puts great pressure on the budget of wind power project roads. Summary of the invention

[0003] The object of the present invention is to provide a ground paving device for mountain road saddles in new energy wind farms, thereby solving the above-mentioned problems existing in the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a saddle paving device for mountain roads in new energy wind farms, including a foldable pavement composed of multiple rows and columns of fixed steel plates, guardrails are arranged on both sides of the upper side along the length of the foldable pavement, the guardrails are connected to both sides of the road and are unfolded upward, and covering plates are arranged on both sides of the lower side along the length of the foldable pavement, the covering plates are connected to both sides of the road, and extend downward along the slope, a plurality of reserved holes are opened on the covering plates, and anchor rods are embedded in the mountain through the reserved holes of the covering plates to fix the covering plates to both sides of the road, and an electro-hydraulic push rod is attached to each fixed steel plate of the foldable pavement, and the electro-hydraulic push rod extends downward to contact and support the mountain when there is a gap between the foldable pavement and the mountain.

[0005] The length and angle of the foldable road surface are adjustable, and the fixed steel plates are connected by foldable hinges, so that the road surfaces of different lengths and widths can be combined according to the terrain.

[0006] The fixed steel plate is welded by an upper steel plate and a lower steel plate, two I-beams in a well shape are welded horizontally and vertically between the two steel plates, and the foldable hinge is embedded in the edge of the fixed steel plate.

[0007] The upper and lower steel plates are formed by welding two 3-6 cm thick square steel plates at a distance of 20-30 cm.

[0008] The cover plate is formed by splicing a plurality of steel plates through movable hinges and can be folded and the angle can be controlled.

[0009] The cover plate can be embedded in the interior of the mountain at an acute angle to the foldable road surface.

[0010] The beneficial effects of the present invention are: the prefabricated splicing technology is adopted, and the paving can be quickly installed in a narrow saddle-shaped terrain, which not only saves construction time, but also can be reused. Compared with the traditional retaining wall solution, it saves budget and solves the problem of abandoning the machine position due to terrain problems. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Specifically, the ground paving device for the saddle of a mountain road used in a new energy wind farm in this embodiment includes a foldable road surface 1, an electro-hydraulic push rod 6, a covering plate 2, an anchor rod, and a baffle 4. The foldable road surface 1 is connected by fixed steel plates 8 through a foldable hinge 5, and each fixed steel plate 8 is welded by two upper and lower steel plates and an I-beam 7 that plays a supporting role in the middle; according to the depth of the mountain saddle, an electro-hydraulic push rod 6 with a telescopic length of the support rod 15 matching the depth of the mountain saddle is selected, and the electro-hydraulic push rod base 14 is connected to the upper steel plate of the fixed steel plate 8 by bolts; according to the width and length of the mountain saddle, the number and arrangement and combination of fixed steel plates 8 are selected, and connected through foldable hinges 5. After the foldable pavement 1 is laid, the electro-hydraulic push rod 6 is controlled to start working until the support rod 15 contacts the mountain and plays a supporting role; the electro-hydraulic push rod 6 is placed at the center of the foldable pavement 1, and one is attached to each fixed steel plate 8; the cover plate 2 is connected to the fixed steel plate 8 through the foldable hinge 5, and the cover plate 2 is arranged on both sides of the foldable pavement 1 and extends downward along the slope; after the cover plate 2 is laid, the anchor rod is driven into the mountain through the reserved hole 3 of the cover plate 2.

[0025] The extended length and width of the prefabricated foldable pavement 1 are determined according to the length and width of the saddle. The length of the covering plate 2 is consistent with the length of the foldable pavement 1. The downward extended width can be determined by calculating the number of anchor rods required based on the weight of the vehicle that the foldable pavement 1 needs to bear. The electro-hydraulic push rod 6 can be replaced freely. According to the maximum transport weight, the electro-hydraulic push rod 6 model with appropriate supporting weight and the telescopic length of the support rod 15 adapted to the depth of the saddle is selected.

[0026] In this embodiment, the foldable pavement 1 is formed by eight double-layer square fixed steel plates 8 with a side length of 1 to 1.5 meters, which are spliced ​​together by foldable hinges 5. The upper and lower layers of square fixed steel plates 8 are 4 to 6 cm thick, and the foldable pavement is 30 to 40 cm thick. Four I-beams 7 are welded in a "well" shape between the two square fixed steel plates 8, with a height of 25-35 cm.

[0028] In this embodiment, the covering plate 2 is composed of sixteen single-layer square fixed steel plates 8 with a side length of 0.8 to 1.2 meters spliced ​​together by foldable hinges 5. The thickness of the square fixed steel plates 8 is 2 to 4 cm. Anchor holes 3 are reserved in the middle position and are arranged in four rows, with four plates in each row.

[0029] In this embodiment, the anchor rod is a HRB335 threaded steel bar with a diameter of 18 to 22 cm and a length of 2.5 m.
