Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology and solve the problem of high road smoothness due to the limitation of vehicle speed in the prior art, the road surface is prone to local bulges or depressions after long-term use due to different geological conditions, and it is necessary to pass through the road surface The correction device is used to level and restore good driving conditions, but the existing equipment can only strip and re-pave the asphalt layer of the road surface, and cannot solve the depression and settlement caused by roadbed factors, and the recurrence rate of road surface injuries in the short term after repair Higher, seriously affecting driving safety, increasing the number of maintenance, and occupying the road during the maintenance period is a prominent problem. A highway road surface finishing device proposed by the present invention

Abstract

The invention belongs to the technical field of road engineering, and particularly relates to an expressway pavement finishing device which comprises a vehicle body and a milling roller. The milling roller is rotationally connected with the vehicle body through a bracket and is driven by a hydraulic motor to rotate; a group of oil cylinders are arranged at the bottom of the vehicle body at the side, close to the tail of the vehicle body, of the milling roller, driving units are fixedly connected to the ends of piston rods at the tops of the oil cylinders, and drilling barrels are rotationally connected to the bottoms of the driving units and penetrate through holes in the bottom of the vehicle body; the drilling barrels are driven by the driving unit to rotate; a storage box is fixedly connected in the vehicle body, the bottom of the storage box is communicated with a concrete pump, and an outlet of the concrete pump is rotationally and hermetically connected with the drilling barrel through a pumping pipe; sunken roadbed is uniformly punched through the drilling cylinder, and then rapid hardening concrete is pumped into the drilled hole through the concrete pump to form a pile. Thus, the bearing capacity of the roadbed is increased, and the recurrence of pavement injuries is reduced.

Description

technical field [0001] The invention belongs to the technical field of road engineering, in particular to an expressway road surface finishing device. Background technique [0002] With the continuous development of cities and traffic construction, a large number of expressway pavements are facing maintenance and repair. There are many measures for maintenance and repair, such as milling and resurfacing, recycling and so on. In the prior art, because there are many kinds of road surfaces (such as asphalt road surface, cement road surface, pedestrian road surface), maintenance and repair need to adopt a variety of equipment, which is relatively troublesome, resulting in many road surface maintenance and repairs not being timely, and the performance of the road surface gradually deteriorates. [0003] There are also some technical solutions about road engineering in the prior art. For example, a Chinese patent with the application number 201921171172X discloses a recycled asp...
