Road engineering pavement leveling machine

Abstract

The invention discloses a road engineering pavement leveling machine, and belongs to the technical field of pavement leveling. A road engineering pavement leveling machine comprises a moving seat, a collecting groove is formed in the advancing side of the moving seat, and the advancing side of the collecting groove and the moving seat are fixedly connected with a shovel plate; a rolling shaft is rotatably arranged on the side, close to the shovel plate, in the collecting tank, and a plurality of soil breaking wheels are fixedly arranged on the rolling shaft; a plurality of leaking holes are formed in the bottom wall of the collecting tank; a rolling wheel is further rotationally arranged at the bottom of the moving base and arranged on the side, away from the rolling shaft, of the collecting groove. According to the device, the uneven position of the roadbed can be flexibly repaired and leveled in a targeted mode, the guarantee for the flatness of the roadbed is greatly enhanced, operation is easy, use is convenient, and the convenience degree is high.

Description

technical field [0001] The invention relates to the technical field of road leveling, and more specifically, relates to a road leveling machine for road engineering. Background technique [0002] Pavement roughness refers to the deviation value of the unevenness in the longitudinal direction of the road surface. The road surface roughness is an important index in the evaluation of the road surface and the acceptance of the road construction. For this indicator, during the roadbed construction process of highway engineering, the staff usually need to use leveling equipment to level the paved roadbed soil surface, so as to ensure that the road surface can ensure that the asphalt thickness is more uniform after the asphalt is added. More flatness. Most of the existing leveling machines are equipped with large rollers to squeeze and flatten the road surface.

[0002] Pavement roughness refers to the deviation value of the unevenness in the longitudinal direction of the road surface. The road surface roughness is an important index in the evaluation of the road surface and the acceptance of the road construction. For this indicator, during the roadbed construction process of highway engineering, the staff usually need to use leveling equipment to level the paved roadbed soil surface, so as to ensure that the road surface can ensure that the asphalt thickness is more uniform after the asphalt is added. More flatness. Most of the existing leveling machines are equipped with large rollers to squeeze and flatten the road surface. Although it can effectively compact the road surface, it has a relatively high protrusion It is difficult to flatten the protruding part in a large subgrade position, and there will be a problem of bulging even after leveling, which will affect the subsequent work of laying asphalt, although the flatness index can be achieved by changing the thickness of the asphalt , but this will cause the quality of the road surface to decline. Moreover, the compaction of the road surface by the roller is mostly achieved by the weight of the roller itself and the leveler. The compaction effect achieved in this way It can only act on the soil part of the roadbed, and there is a gravel layer under the roadbed. It is difficult to fill the gaps in the gravel layer by weight suppression, and then it will cause voids under the road surface during the long-term opening of the road. The drum will greatly shorten the service life of the road surface. In view of this, we propose a road leveling machine for road engineering
