The confusion and countermeasures faced by the road mechanized maintenance center
1. The scale of construction of road mechanized maintenance center
In formulating the planning of the scale of mechanized maintenance center, we should start from adapting to the needs of economic and social development, adapting to the trend and requirements of future socio-economic development, breaking the administrative boundary of small regions, breaking the maintenance boundary, reasonably determining the radiation radius of the maintenance center, in which large scale to maintain highways and one or two highways, maintenance mileage above 300km, covering an area of about 30 acres, the scale of housing construction 1500m2, auxiliary facilities 200m2, machinery and equipment supporting 10 million yuan; medium-sized to maintain trunk highways and county highways of high secondary pavement, maintenance mileage in more than 200km, covers an area of about 20 acres, building scale of 1000m2, auxiliary facilities 150m2, machinery and equipment supporting 5 million yuan; small to maintain trunk highways, maintenance mileage in 100km above, covers an area of about 10 acres, building scale 500m2, ancillary facilities 100m2, machinery and equipment supporting 3 million yuan.
Mechanized maintenance center plan construction, it is recommended to refer to the following programs.
1. Pain points of grass-roots maintenance machinery operation
(1) Few product varieties, incomplete specifications, insufficient maintenance machinery supporting rate
(2) Poor product reliability, low life span, high failure rate and short average trouble-free working time
(3) the lack of maintenance machinery special chassis, product automation is not high, the lack of maintenance mechanized personnel
(4) input costs, use costs do not match
(5) low operational efficiency and poor results
2. Road too targeted equipment solutions
| Content of conservation operations | Conventional configuration equipment and drawbacks | Lutai optimization equipment and advantages |
| Road sweeping and cleaning | Manual sweeping or simple equipment sweeping, labor-intensive, not environmentally friendly | Towed sweeper or road sweeper, mechanical sweeping, environmentally friendly and strong |
| Conventional Crack Treatment | Grouting machine, low utilization, idle phenomenon is common | Grouting treasure, many people work at the same time, melting efficiency, not aging |
| Small area pothole repair | Integrated maintenance vehicles, high acquisition costs and high operating level requirements | Single drum integrated maintenance machine, non-stick, non-aging, high efficiency |
| Large area pothole repair | Large station centralized treatment with seasonal restrictions | Micro-mixing station + asphalt insulated transport box, unfavorable seasonal autonomy |
