湖南大慈公路的路面是组织民工采用大流水作业铺装的。实行大流水作业,不但可以使民工迅速掌握操作技术,而且因为集中使用工具的关系,还可以大大减少购置工具的费用(如挖路槽和整理路容的小组,就不需要耕犁和较多的水桶,底、面层组可以不配备黄土筛和较多的锄头)。兹将这种作业的主要内容介绍如下: 一、组织分工路面施工分四个组。第一组是路槽兼采结合料组,任务是:整平路基,挖路槽,采备黄土,挖盲沟,填卵石,夯填盲沟,铺贴草皮,碾压路槽(3—4遍),整平路槽等。第二组是底层铺装组,任务是:铺装级配砾石(或泥结碎石)底层或人工基础,碾压底层(人力碾压时碾压5—6遍,压路机碾压时碾压两遍),培底层、路肩(以防碾压时侧向移动),整补底层等。第三组是面层铺装组,任务是:铺装级配砾石(或泥结碎石)面层,碾压面层(人力碾压时碾压4—5遍,用压路机碾压时只压两遍),培路肩,整补 The road of Hunan Dicu Road is to organize migrant workers to use large running water for paving. The implementation of large-scale water operations not only enables migrant workers to quickly grasp operational techniques but also greatly reduces the cost of purchasing tools due to the centralized use of tools (such as digging trenches and sorting out road capacity, eliminating the need for plowing and more Bucket, bottom, surface layer group may not equipped with loess screen and more hoes). The main content of this operation will be introduced as follows: First, the division of labor Pavement construction is divided into four groups. The first group is combined with the road and the combination of materials group, the task is: leveling roadbed, digging road trenches, mining loess, digging blind ditch, fill pebbles, ramming filling blind ditch, paving the turf, 4 times), leveling road trough and so on. The second group is the bottom pavement group, the task is: pavement grading gravel (or clay bonded stone) the bottom or artificial foundation, rolling the bottom layer (when the human rolling compacted 5-6 times, roller compaction rolling Twice), Pei bottom, shoulders (to prevent lateral movement when rolling), to complement the bottom and so on. The third group is the surface pavement group, the task is: pavement grading gravel (or clay bonded stone) surface, rolling the surface layer (when the human rolling compacted 4-5 times, with roller compaction Pressure twice), training road shoulder, make up
