A first sliding sleeve 6 is provided on two of the insertion rods 5 located at the bottom of the right frame beam 4, and a second top column 7 is provided at the bottom of the first sliding sleeve 6; both the left frame beam 1 and the right frame beam 4 include a vertical beam, a cross beam and a longitudinal beam.

A rotatable positioning sleeve 8 and a steel drill rod 9 structure are also installed at the bottom of the longitudinal beam to realize inclined support on both sides of the left frame beam 1 and the right frame beam 4.

[0028] In the temporary widening structure of the road in this wind farm, the left frame beam 1 and the right frame beam 4 are temporarily installed at the road collapse by the first top column 2. Then, the right frame beam 4 is matched with the docking sleeve 3 of the left frame beam 1 through the insertion rod 5 to adjust the relative positions of the left frame beam 1 and the right frame beam 4, so that the left frame beam 1 and the right frame beam 4 are close to both ends of the road collapse pit, realizing the assembly of the left frame beam 1 and the right frame beam 4 into an integral support frame and placing it in the collapse pit. Then, by inserting the steel drill 9 on the positioning sleeve 8 into the pit walls at both ends of the collapse pit, the left frame beam 1 and the right frame beam 4 are inclinedly supported to prevent the left frame beam 1 and the right frame beam 4 from tilting to the left end or the right end under the action of external forces. Then, by laying the steel plate 11 on the left frame beam 1 and the right frame beam 4, the temporary widening treatment of the road surface at the collapse of the road can be realized, ensuring that vehicles can pass normally. The temporary widening structure of the road in this utility model is convenient, fast for assembly and disassembly, and simple in operation. The positions of the left frame beam 1 and the right frame beam 4 can be adjusted according to the length of the collapse pit to meet the use requirements. The frame is reliably supported by the first top column 2, the second top column 7 and the steel drill 9, ensuring the firm stability of the whole widening structure and the safe passage of vehicles.

[0029] A preferred embodiment of this specific method is that the bottoms of the first top column 2 and the second top column 7 are provided with telescopic top rod structures.

In this embodiment, the top rod 12 can adjust the distance extending downward from the first top column 2 and the second top column 7 up and down, so as to realize the adjustment of the heights of the left frame beam 1 and the right frame beam 4, meeting the temporary widening requirements of collapse pits with different depths.

[0031] A preferred embodiment of this specific method is that a locking nut 13 capable of abutting against the bottom surfaces of the first top column 2 and the second top column 7 is provided on the screw rod part of the top rod 12.

By hitting the hammer head, the steel drill rod 9 can be obliquely inserted into the pit wall of the collapsed pit, and then by rotating the limit nut 10 to abut against the bottom surface of the positioning sleeve 8, the positioning sleeve 8 can be supported, so as to realize the inclined support for the left frame beam 1 and the right frame beam 4, and prevent the left frame beam 1 and the right frame beam 4 from tipping forward or backward;

[0034] Moreover, the positioning cylinder 14 of the limit nut 10 is adapted to the inner wall of the positioning sleeve 8, so that there is no relative movement between the positioning sleeve 8 and the steel drill rod 9, realizing the reliable positioning of the steel drill rod 9 and the positioning sleeve 8; in actual use, the rotation angle of the positioning sleeve 8 can be adjusted according to the actual terrain, so as to adjust the inclination angle of the steel drill rod 9.

[0035] A preferred embodiment of this specific method is that second sliding sleeves 15 are provided on the four plugging rods 5, and a support rod 16 is connected between two adjacent second sliding sleeves 15. Adjusting the positions of the four second sliding sleeves 15 can adjust the supporting positions of the support rod 16 for the four plugging rods 5, ensuring reliable support for the middle part of the entire widening structure.

[0038] A preferred embodiment of this specific method is that a positioning boss 19 adapted to the positioning groove 18 is provided at the bottom of the pad 11. The pad 11 is of a steel plate structure and can undergo elastic deformation under pressure. The bottom surface of the positioning boss 19 is arranged in contact with the cross beam, and the pad 11 is quickly assembled through the cooperation of the positioning boss 19 and the positioning groove 18.

[0039] A preferred embodiment of this specific method is that guide rods 20 are horizontally penetrated through the longitudinal beams on both sides of the left frame beam 1 and the right frame beam 4, a limiting plate 21 capable of abutting against the side part of the pad 11 is provided at the inner end of the guide rod 20, and a spring 22 is provided on the guide rod 20 between the limiting plate 21 and the longitudinal beam. The provided telescopic limiting plate 21 further limits both sides of the pad 11 to prevent the pad 11 from deflecting.

[0040] A preferred embodiment of this specific embodiment is that a limiting convex block 23 is provided at the top inside the limiting plate 21. An inclined wedge surface is provided at the top of the limiting convex block 23. The bottom surface of the limiting convex block 23 can be attached to the top surface of the backing plate 11. The limiting convex block 23 provided on the limiting plate 21 can vertically limit the backing plates 11 on both sides to prevent the backing plates 11 on both sides from warping.

[0041] Working principle:

[0042] The left frame beam 1 and the right frame beam 4 are temporarily installed at the road collapse site through the first jack 2. Then, the right frame beam 4 is matched with the docking sleeve 3 of the left frame beam 1 through the insertion rod 5 to adjust the distance between the left frame beam 1 and the right frame beam 4, so that the left frame beam 1 and the right frame beam 4 are close to both ends of the road collapse pit, realizing the assembly of the left frame beam 1 and the right frame beam 4 into an integral support frame and placing it in the collapse pit. Then, the steel pins 9 on the positioning sleeves 8 are obliquely inserted into the pit walls at both ends of the collapse pit to realize the inclined support for the left frame beam 1 and the right frame beam 4, preventing the left frame beam 1 and the right frame beam 4 from tilting to the left end or the right end under the action of external forces; then, by laying the steel plates 11 on the left frame beam 1 and the right frame beam 4, the temporary widening treatment of the road surface at the road collapse site can be realized to ensure that vehicles can pass normally; the top rod 12 can adjust the height up and down, and can adapt to the uneven foundation in the collapse pit. The height of the backing plates 11 at the tops of the left frame beam 1 and the right frame beam 4 has good adaptability, which is convenient for the layout and installation of the entire widening frame; the temporary widening structure of the wind farm road of the present invention is convenient and fast to assemble and disassemble, simple to operate, can adjust the positions of the left frame beam 1 and the right frame beam 4 according to the length of the collapse pit to meet the use requirements, and the frame is reliably supported by the first jack 2, the second jack 7 and the steel pins 9 to ensure the firm stability of the entire widening structure and ensure the safe passage of vehicles.
