黑龙江省青冈公路机械厂职工(原青冈公路管理站技术革新小组)在毛主席革命路线指引下,以大庆为榜样,发扬独立自主、自力更生的革命精神,土法上马,因陋就简,修旧利废,经过上百次的试验和四次大改进,于1974年研制了一台能够自动上料、自动拌合、自动摊铺的自行式渣油路面联合铺路机(见图1)。该机使上料、供油、拌合、摊铺等项作业实现了机械化,因而提高了施工工效和铺路质量,减轻了劳动强度,改善了劳动条件,实现了安全生产,延长了施工季节。如以每天按7小时工作计算,一天铺路可达2公里以上。为我国 Employees of the Qinggang Highway Machinery Plant in Heilongjiang Province (formerly the Technical Innovation Team of the Qinggang Highway Management Station), under the guidance of Chairman Mao’s revolutionary route, took Daqing as an example to carry forward the revolutionary spirit of independence and self-reliance. The earthwork was launched, and because of the simplicity, old repairs and wastes were passed through. Hundreds of tests and four major improvements, in 1974 developed a self-residue residing road paving machine capable of automatic feeding, automatic mixing, and automatic paving (see Figure 1). The machine has enabled the mechanization of operations such as feeding, fueling, mixing and paving, thereby improving construction efficiency and paving quality, reducing labor intensity, improving working conditions, achieving safe production, and extending the construction season. If you work on a daily basis for 7 hours, you can paved more than 2 kilometers a day. For our country
