Asphalt laying reciprocating type compaction device for highway engineering construction and implementation method of asphalt laying reciprocating type compaction device

Abstract

The invention discloses an asphalt laying reciprocating type compaction device for highway engineering construction, a small transmission wheel drives a large transmission wheel to rotate through a transmission belt, a movable rod moves and drives a movable sliding set to do reciprocating linear motion on a guide rail at the same time, then a compaction roller moves front and back, asphalt is rolled back and forth, it is guaranteed that asphalt has certain rudiment during vibration tamping, the phenomenon of unevenness caused by direct tamping is avoided, and the compaction roller moves back and forth in a linear mode. The invention further discloses an implementation method of the asphalt laying reciprocating type compaction device for highway engineering construction, the rotation directions of a first gear and a second gear are the same, the rotation directions are the same, hard staggered force can be avoided, damage caused by too firm asphalt is avoided, meanwhile, the multiple sets of scrapers are arranged and attached to the outer wall of the compaction roller, the scrapers can rotate along with a cleaning cylinder to scrape the compaction roller, the rotation speed of the cleaning cylinder is higher than that of the compaction roller, the scraping force is improved, and the damage rate is reduced.

Description

technical field [0001] The invention relates to the technical field of road construction devices, in particular to an asphalt paving reciprocating compaction device for road engineering construction and an implementation method thereof. Background technique [0002] 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 from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, the base layer can also use rigid cement concrete or semi-rigid hydraulic materials. The compaction of asphalt mixture is an important aspect of asphalt pavement construction, and it is a very import...

AI Technical Summary

Problems solved by technology

[0003] In the compaction operation of highway engineering, roller compaction and vibratory compaction are usually carried out separately. Due to the flexibility of the asphalt material, the asphalt material is prone to slight deformation after a long time of roller compaction. At the same time, the process of roller compaction takes a long time. Long, many times, can only be carried out from the beginning to the end, can not be compacted repeatedly, the compaction effect is general, secondly, because the asphalt has a certain viscosity, the existing scraping mechanism causes the scraping to be carried out by the rotating force of the drum, However, the roller rolls slowly, resulting in a small scraping force, which cannot be cleaned well, and the scraping mechanism is often stuck and damaged
