我队于1982年在果洛州大武镇铺筑了3.42公里(路面宽15米)的渣油表处,从三年的使用情况看,起到了美化城镇,利于行车的作用,效果较好。在高寒地区如何修好渣油表处,现将我们的做法和体会介绍如下: 一、气候特点该地处在海拔3,720m以上,公路自然区划为Ⅶ区,属高寒区。24年来的气象资料表明:年平均最高温度达8.1℃,极端最高温度达26.6℃;年平均最低温度达-7.8℃,极端最低温度达-34.9℃。夏季降雨多集中,冬季冰冻时间长。最大冻深达2.02m。由于这些自然因素作用,给该地区铺筑渣油
Our team laid a 3.42km (15m wide) residue meter in Dayu town, Guoluo state in 1982. From the three years’ usage, it has played a role of beautifying the towns and driving traffic, and the effect is better. In the alpine region how to fix the residue table, now we approach and experience are described below: First, the climate characteristics The place is located at an elevation of 3,720 m above the natural division of the highway for the Ⅶ area, is a cold area. The 24-year meteorological data show that the annual average maximum temperature reaches 8.1 ℃, the extreme maximum temperature reaches 26.6 ℃, the annual average minimum temperature reaches -7.8 ℃ and the extreme minimum temperature reaches -34.9 ℃. Concentration of summer rainfall, winter frozen for a long time. The maximum freezing depth of 2.02m. Due to these natural factors, residual oil is laid in the area
