Recently,the total investment in the highway segment Jiuquan crack sealing machine, blower and other mechanical vehicles,using pouring technology, crack sealing material Doan pouring glue and self-developed rubber powder, prepared asphalt, 312 State Line Road, Highway 214, Highway 314, Highway 302 and Ka highway pavement line thorough treatment. Up to now, the road pouring reached 29860 linear meters.
Due to the impact of climate and traffic load and other factors, 312 State Line Road, Highway 214, Highway 314, Highway 302 and Ka line highway pavement cracks. To effectively prevent further cracking pavement, water seepage, aging, extend the life of the road, use the paragraph in fine weather, the temperature suitable for favorable conditions and concentrate on raising administer sections of pouring. Recalling that paragraph pouring work in previous years, summed pouring technology experience and lessons learned, early crack sealing machine hire professionals conducted a systematic maintenance, procurement Reid pouring sealant over 30 tons, developed and put into rubber powder, asphalt potting material prepared potting, avoid pouring past is not dense, uneven thickness, the high cost.
To maintain the quality and quantity on schedule to complete the work of pouring the paragraph to take "three strict three fine, three in place" measures, "three strict": that is, strict construction management and strict operating procedures, strict quality of pouring.”Three fine": that is, carefully brush the seam, remove debris in the joints; blow carefully sew, sew remove dust inside; pouring carefully to ensure that the full amount of oil in the joints and not outside the silt. "Three in place": First oil perfusion within the fracture in place to ensure fuel adhesion; the second is to guide technicians in place to track, do a good job records, ready to solve the problems in construction; Third, safety management in place, requiring construction workers must the safety logo clothing, construction site safety warning signs set up eye-catching, and a full-time security staff to divert traffic.
With decades’ development, Shanghai Doan Machinery Technology Co.,Ltd. have absorbed the top technical talents to keep continuous innovation in leading high-end road maintenance equipment.
