As a major traffic artery connecting the core business district of the old city and the northern new district in a certain city, Daqing Road has a total length of approximately 3.2 kilometers. It handles an average daily traffic volume of over 25,000 vehicles, with peak-hour traffic exceeding 4,000 vehicles per hour. Meanwhile, it undertakes the daily travel needs of 3 large residential communities and 2 schools in the surrounding area. In the second quarter of 2024, the municipal authorities launched the full-section renovation project of Daqing Road, with manhole cover renewal as a key link. After multiple rounds of comparison and selection, Chang'an SMC composite manhole covers were finally adopted.
Chang'an SMC manhole covers on Daqing Road have been in use for 8 months. According to the follow-up statistics by the municipal authorities and public satisfaction surveys, remarkable results have been achieved:
· Road traffic noise has been significantly reduced, with nighttime noise complaints from surrounding communities dropping from more than 10 cases per month to zero.
· No settlement or damage has occurred to the manhole covers, and there is no waterlogging backflow on rainy days, greatly improving the safety of pedestrians and vehicles.
· In the quarterly public satisfaction survey conducted by the municipal authorities, the score of "road facility experience" for Daqing Road rose from 68 points (before renovation) to 92 points.
· Only 2 rounds of routine inspections were conducted within 15 years, and no manhole cover maintenance incidents occurred. Compared with traditional cast iron manhole covers, the maintenance frequency has been reduced by 80%, saving approximately 18,000 yuan in operation and maintenance labor costs.
· The manhole covers have no theft risk, completely solving the "road hazard" problem caused by frequent theft of traditional cast iron manhole covers.
The application case of Chang'an SMC manhole covers on Daqing Road has become a benchmark for the update of municipal road facilities in the city. At present, 3 renovation projects of major urban arterial roads plan to adopt this solution, gradually promoting the application of SMC composite manhole covers and advancing the upgrading of urban road infrastructure towards "safe, quiet, durable, and environmentally friendly".
