During the road construction, in order to avoid interruption of traffic, will lay the steel plate to ensure vehicle traffic, but the steel plate in the vehicle rolling is not only easy to skid, but also due to Qiaojiao injury tires. Reporters on the 11th was informed that the Municipal Engineering Group Road and Bridge Maintenance and Repair Branch recently in the maintenance of Jiaoning Elevated Road expansion joints, the paving of steel to avoid the drawbacks of the past. Steel surface adds a high-tech material coating, used to ship-borne aircraft landing,[url=http://roadmachinerysuppliers.com/wholesale/2019.html]slurry seal coat[/url] this is the first time for the municipal road maintenance. The past two days, Jiao Ning Elevated Road, west to east direction, Nanjing Road to Yinchuan West Road Bridge under the bridge section, every 11 pm or so began to close the construction until the next morning around 6 am to open up traffic. It is understood that the closure of the construction is to carry out maintenance of an expansion joint maintenance, distance Yinchuan West Road about 200 meters under the bridge. In order to prevent the elevated road surface due to thermal expansion and contraction caused by local damage, in each joint between the bridge design expansion joints .Pridge bridge expansion, expansion joints pitch smaller, winter cooling after bridge shrinkage, expansion joint gap Municipal Engineering Group Road and Bridge Maintenance and Repair Branch, Mr. Zhang introduced the technical staff, in general, in accordance with national standards, the gap should not exceed 8 cm. "The current expansion joints have exceeded the standard parts." Mr. Zhang said that the gap is too large, not only to the inconvenience of traffic vehicles in the past, but also lead to displacement in the expansion joint water stop, making the bridge lost Water effect, when it rains, the rain under the expansion joints under the leak, the bridge below has become a "Shuilian Dong." In addition, garbage, dust, etc. will be leaked down,[url=http://roadmachinerysuppliers.com/pavement/2252.html]surface treatment road equipment supplier[/url] there are security risks. At present, less traffic at night when the closure of the construction, a total of about 40 meters to replace the expansion joints, duration will continue until the end of this month. As Jiao Ning Elevated Road traffic density, in order to ensure the normal passage of vehicles during the day, the need for temporary laying of steel plate in the maintenance site. Construction unit of the person concerned, the traditional steel plate is easy to skid, Qiaojiao, owners will pay attention to a little damage caused by car accident, and grinding noise when rolling, affecting the surrounding residents. This time maintenance and repair, the construction unit has just developed a new island Castle, the traditional steel plate surface coating of a high-tech coating, not only solved the problem of vehicle traffic, but also to avoid the laying of the past, the common drawbacks of steel . It is reported that this steel by the Qingdao Polytechnic University,[url=http://roadmachinerysuppliers.com/pavement/4945.html]lawn blowers for sale[/url] Professor of Civil Engineering, Qingdao Guogong New Materials Co., Ltd. Chief Engineer Huang Weibo led the team to develop, using the military aspects of carrier-based aircraft landing technology for the first time in municipal maintenance projects. Trial a few days since the effect is obvious, the future is expected to Castle in all municipal construction in the promotion.
