春融时对道路翻浆的预防北京道路翻浆发展时期,约从三月半到四月半,预防道路翻浆在春融以前就已开始。我们的预防办法:①根据历年道路情况(地下水、表面水的排除,路面逐年翻浆情况等)和现状(交通量、冻冰深度、路面的变形等)作好调查,确定可能翻浆的道路,尽可能封闭交通,禁止重型车辆在翻浆发展时期通行,或级织重型车辆绕行。②路堑地段挖汇水沟宣泄路基水份。应先挑修侧沟,使汇水沟加深1～1.5公尺,以便把路基水份汇集排除路肩较宽或预计翻浆严重时,另外在路面边缘于路肩上修筑明沟,宽20～30公分,深度可针对冻层厚
Preventive measures for road bleaching at spring meltdown Beijing road bleaching period of development, from about half of March to April and half, to prevent road bleaching in the spring before the melt has begun. Our preventive measures: ① According to the road conditions over the years (groundwater, surface water exclusion, road conditions, etc.) and the status quo (traffic volume, the depth of ice deformation, deformation of pavement, etc.) to investigate and determine the road may dip, do Traffic may be blocked, heavy vehicles are prohibited from passing through during the development of the dumping paddy, or heavy duty vehicles are bypassed. ② cutting section dug ditch catharsis embankment moisture. The side ditch should be picked first to deepen the catch ditch 1 to 1.5 meters in order to put the roadbed water together to exclude a wide range of road shoulder is expected or severe when the pulp is also the edge of the road in the road to build open ditch, 20-30 cm wide, Depth for frozen layer thickness
