Better road surface flatness can not only make vehicle traffic safer and more efficient, but also greatly increase the service life of the road, while also reducing operation and maintenance investment. Asphalt concrete paving on ordinary roads generally uses steel chisels to fix steel wire ropes, and the elevation is controlled by adjusting the steel wire rope to the fixed position on the steel chisel.

Drill holes on the upper part of the completed crash barrier. Directly pave according to the current status of the roadbed. If the previous elevation control is not good, there will be various potholes after the asphalt paving is completed. Drill holes in the completed crash barrier and use bolts to fix the hanging wire bracket. The crash barrier often adopts a reinforced concrete structure. Manual demolition takes a long time and is difficult to construct. Drilling holes in the wall may also destroy the stability of the overall structure of the crash barrier and need to be repaired later.

[0021] The elevation adjustment mechanism includes a vertical channel steel 5 and a movable plate 8. A vertical channel steel 5 is arranged at the left end of each horizontal cross bar 1. A vertical limit hole 6 is arranged at the upper part of each vertical channel steel 5. The end of the horizontal cross bar 1 passes through the vertical limit hole 6 to connect with the vertical channel steel 5. An elevation limit hole 7 is arranged at the lower part. Bolts pass through the elevation limit hole 7 to movably fix the movable plate 8 in the notch of the vertical channel steel 5. A connecting hole 9 is arranged at the lower part of the movable plate 8. A connecting ring 10 is provided in the connecting hole 9, and the two connecting rings 10 are connected by a wire rope 11, and the wire rope 11 is used to place the sensor; the sliding mechanism includes roller one 2 and roller two 13, roller one 2 is a horizontal roller, and roller two 13 is a vertical roller. Roller one 2 is installed between the two horizontal channel steels 3 of each horizontal cross bar 1, and a vertical longitudinal rod 12 is provided at the right end of each horizontal cross bar 1, and roller two 13 is installed at the lower end of the vertical longitudinal rod 12.
