Municipal arterial road renovation project
Project Background
A major road renovation project in Datong City has a total length of 3.2 kilometers, with a red line width of 40 meters. It includes old pavement removal, pipeline renovation, roadbed reconstruction, and asphalt paving. The construction area is located in the core of the urban district and requires high flexibility of equipment and low-noise operations.
Core equipment
Hengyue Heavy Industry HY215-9D small excavator (main equipment)
Supplementary equipment: pavement milling machine, loader, small roller
Device Application Highlights
Urban Construction Compatibility: The HY215-9D has a compact body and a small turning radius, enabling it to smoothly navigate through narrow construction areas. It can work in tandem with a breaker to efficiently remove old cement pavements, avoiding disturbances to surrounding buildings and residents.
Multi-Process Collaborative Operations: The equipment can quickly switch between various attachments such as breakers, buckets, and grabs, simultaneously completing pavement removal, trench excavation, and waste clearance, achieving “one machine for multiple uses” and reducing the number of equipment entries.
Low Noise and Environmental Protection Performance: The optimized engine noise reduction design effectively reduces noise during urban construction, meeting environmental protection construction requirements. No noise complaints were received during the project period.
Project Results
During the stage of old pavement removal and pipeline renovation, the operational efficiency of the equipment was enhanced by 6 times compared to traditional manual methods. The construction period for a single section was reduced to 15 days.
The equipment was capable of flexibly adapting to multiple construction processes, thereby reducing the cost of additional equipment rentals and lowering the overall construction cost by 10%.
