水泥混凝土路面在我国已有多年的使用历史,近年来,我国现有的水泥混凝土路面有相当一部分已接近或超过设计年限,随着交通量的增加,尤其是汽车轴载日益重型化,在连续荷载作用下,出现路面损坏,使用品质下降等情况,水泥混凝土路面最严重的病害路面板的断板直至破碎,而这种情况往往是由于板下脱空所引起的。如果能解决板底脱空问题,那么水泥混凝土路面的使用年限将大大延长,板下灌浆技术是很有效的解决办法,它是通过对水泥混凝土路面板下灌注水泥浆液、水泥粉煤灰浆液、水泥砂浆,充实板底脱空空隙,达到稳定水泥混凝土板块的目的,改善路面通车状况的方法。
Cement concrete pavement has been used for many years in our country. In recent years, a considerable part of the existing cement concrete pavement in our country has approached or surpassed the design life. With the increase of traffic volume, especially the heaviness of automobile axle load, Load under the action of road damage, the use of quality decline, the worst case of concrete pavement road plate broken until broken, and this situation is often due to the board caused by the void. If you can solve the problem of emptying the bottom of the board, then the service life of the cement concrete pavement will be greatly extended, under the grouting technology is a very effective solution, it is through the cement concrete pavement perfusion cement slurry, cement fly ash slurry, Cement mortar, filling the void at the bottom of the board, to achieve the purpose of stabilizing the cement concrete plate, to improve the traffic conditions of the road.
