Pavement repairing device for highway engineering

Abstract

The invention discloses a pavement repairing device for highway engineering. Stirring rods and stirring blades are driven to stir through the rotation of a stirring motor, so that the stirring rods and the stirring blades can fully and uniformly stir asphalt and fine stones placed inside a stirring box, meanwhile the asphalt and the fine stones are fully stirred and mixed, and thus, the repairingeffect of the asphalt and fine stones on the pavement and pot holes of a highway and the practicability are improved; an impact column reciprocates up and down through the rotation of a rotating motorto drive a tamping plate to reciprocate up and down, the tamping plate is used for constantly up and down knocking and tamping, the mixture of the asphalt and the fine stones is tamped by the tampingplate with no need for manual work, thus, the labor intensity is reduced, and the tamping effect and the working efficiency are improved; the pavement repairing device can quickly repair the highwaypavement and prevents the staff from occupying the road for a long time to repair the pavement and affect traffic; and the use reliability of the pavement repairing device is improved when the tampingplate is used for tamping certain pavement several times.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for road surface maintenance, in particular to a road surface repair device for road engineering. Background technique [0002] As we all know, asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage caused by driving and natural factors, making the road smooth and less dusty. , impermeable, and durable, therefore, asphalt pavement is the most widely used high-grade pavement in road construction. According to the "Technical Standards for Highway Engineering" of the Ministry of Communications of China, expressways refer to "capable of adapting to the annual average day and night passenger car traffic volume of There are more than 25,000 vehicles, which are specially used for highways with high-speed driving in separate lanes and all access and exits are co...

[0002] As we all know, asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage caused by driving and natural factors, making the road smooth and less dusty. , impermeable, and durable, therefore, asphalt pavement is the most widely used high-grade pavement in road construction. According to the "Technical Standards for Highway Engineering" of the Ministry of Communications of China, expressways refer to "capable of adapting to the annual average day and night passenger car traffic volume of There are more than 25,000 vehicles, which are specially used for highways with high-speed driving in separate lanes and all access and exits are controlled. Therefore, the road surface maintenance requirements for expressways are relatively high. Mixing the mixture of asphalt and fine gravels is a waste of too much manpower, and the mixing efficiency is low. At the same time, the mixing and mixing of asphalt and fine gravels is not sufficient, resulting in poor repair effect of asphalt and fine gravels on highway road pits, and low practicability. Low; and the mixture of asphalt and fine stones is manually rammed with a tamping plate, which is labor-intensive, and the compaction effect is poor, and the work efficiency is low. The highway pavement cannot be repaired quickly, and the staff spends a long time Occupying the road to repair the road surface, affecting traffic, resulting in lower reliability
