Problems solved by technology

[0002] As the foundation and support of the pavement structure, the subgrade plays a key role in the service behavior of the upper pavement structure. However, there are many high-fill embankments in mountainous areas, especially in loess areas. Due to construction problems and the influence of various natural environmental factors, the subgrade subsidence Diseases occur frequently, and cause damage to the pavement structure layer and reduce the flatness, which seriously threatens the normal operation of the road and the safety of people's lives and properties;
[0003] The existing roadbed repair device cannot change the repair ability of the device with the size of the crack, and cannot adapt to various environments

Abstract

The invention discloses a roadbed subsidence repairing device, which belongs to the field of roadbed repairing devices. Monitoring is performed by a road surface monitoring camera installed above a hydraulic installation sleeve. When a cracked road surface is identified, a material conveying moving box arranged at the rear is used to push the front. The device moves to the cracked road, and is also equipped with a hydraulic telescopic rod to expand the rotating moving arm through the linkage deployment mechanism, so as to adapt to different road gaps. When the road gap is large, the hydraulic telescopic rod shrinks and drives the rotating rod around The rotating shaft rotates, thereby driving the rotating moving arm to open to both sides, so that it can adapt to larger cracks. When the rotating moving arm is opened to both sides, it will also drive the moving sleeve to move up, thereby driving the conveying bellows to the upper side. Move to keep the discharge port and the ground at a certain height, to prevent the discharge port from contacting the ground when the moving arm is turned to open to both sides.

Description

technical field [0001] The invention relates to the field of roadbed repairing devices, in particular to a roadbed subsidence repairing device Background technique [0002] As the foundation and support of the pavement structure, the subgrade plays a key role in the service behavior of the upper pavement structure. However, in mountainous areas, especially in the loess area, there are many high-filled embankments. Due to construction problems and the influence of various natural environment factors, the subgrade subsidence Diseases often occur, and cause damage to the pavement structure layer and reduce the flatness, which seriously threatens the normal operation of the highway and the safety of people's lives and properties; [0003] The existing roadbed repairing device cannot change the repairing capability of the device with the size of the crack, and cannot adapt to various environments. SUMMARY OF THE INVENTION [0004] In order to solve the above problems, the pres...
