subject: Nanjing Road Excavation Backfill Application Intech Quick Fix Of New Technologies - Perkins, Road [print this page] 5 21, in Nanjing Xingang Development Zone, a new avenue of Yao, a rare, huge area of over 200 square meters of road disease, in the "Highway doctor" INTECH company independently developed a "city road Fast remediation excavation backfill "the latest technology in less than two days time on the restoration of normal traffic, but also the technology for the first time in Nanjing, was a large-scale promotion within the application.
Discarded building materials through the break, mixing, addition of a dedicated research and development INTECH curing agent, it becomes a foundation material, strength fully comply with the requirements of the new road. INTECH this technology not only solves the problem of building materials for recycling, but also solve the long period of traditional excavation backfill process, low efficiency, can realize the day of backfilling, paving the way for the day, the day of opening. This latest technology has been selected as Construction Department of Jiangsu Province "Jiangsu Provincial Department of Construction Science and Technology Achievement Project", in the Jiangsu province-wide promotion.
200 square meters large two-day settlement road repair disease New Road
Yao and Yao in Nanjing Xingang Development Zone of doors between the cars much traffic every day, many industrial heavy vehicle speeding overhead. Early May, IAC companies conservation construction, found a huge area of over 200 square meters of road disease.
"A large area of road subsidence has occurred, the diagnosis was two gray gravel emergence of more serious problems, should be heavy-duty trucks over this road, the road caused by overloading," INTECH Construction Engineering Division Analysis of the Han Yanfeng manager, said. In accordance with the construction plan, to dig up the road, redo lime gravel. "If the traditional process, using the old material, at least 7 days, taking into account the road with heavy traffic, in order to shorten the construction period, we decided to use the road excavation backfill latest quick fix technology."
In accordance with the requirements of construction, digging the scene after 39 cm of the embankment, a large number of construction waste to be used for part of the original lime gravel laying. As the rapid filling of the material has good mobility, can easily enrich the pore lumen and the hidden foundation, king of additives in thermal radiation by heating heating baking, the backfill material in the curing process does not shrink, solved by material embankment caused by contraction itself, the road sinking. The support of new technologies, construction of asphalt pavement repair then start INTECH's construction team took only two days to complete the repair work there way disease.
Than the traditional process, the higher the quality of the restored road, get blown away by the business units. They presented under construction, new road in Yao similar way elsewhere disease, will also be repaired in this way.
The recycling of construction waste backfill material laying on the road after the patient Department
Variety of wastes can be reused
At the construction site, the reporter saw a large area of road subsidence Way disease being a Excavator Dug, and dug out of the waste have been poured into the edge of the waiting Dump truck Ri. "These wastes can all be recycled again." On-site construction staff, told reporters. The waste is broken asphalt surface was then transported to a dump truck near the mixing plant apart, using the compulsory mixing machine for mixing. Mixing field reporters to see, in addition to transport waste to the asphalt, the mixing inside the building also piled up a lot of rubbish.
Of the construction waste for recycling
"We are the technology type of recyclable construction waste is very broad," Ying Da Han Yanfeng company construction division manager, said, "including the asphalt surface layer of lime, cement stabilized crushed stone, sand rice, pure sandy soil, gravel soil (gravel content of not less than 70%), gravel, pebbles, sand-and so on can be completely recycled, "will be abandoned by this construction waste reprocessed into roadbed materials The technology not only saves a lot of new construction materials, and avoid energy waste and environmental hazards. As the waste material no longer need to prepare for dumping sites, to avoid the use of land and environmental pollution, recycling economy in line with the "reduction" and "reuse" and "resource" principle. With the urban construction and urban
the acceleration of old city reconstruction, resulting in a growing number of waste building material. INTECH's the economy, efficiency, environmental technologies, to solve the transport of construction materials appearances, garbage dumping problems, both to protect the environment, but also to reduce the high transport costs, is undoubtedly of great significance. It is understood that the technology in addition to foundation repair, you can also quickly backfill for the pipeline, pit covers repair and so on, greatly reducing construction time, improve the efficiency of road usage.
