以前我队打水平钻孔拉管作业需要人力多,劳动强度既大、拉管效率又很低。深孔钻进,拉管时间是钻进的5—6倍,甚至8倍,钻进中绝大部分时间花在拉管工序上,成为水平钻孔钻进中的主要问题。通过毛主席著作学习,干部到现场参加劳动,找出了主要矛盾,进行设计,在党委领导下,利用现有材料和废旧料经过短时间试制成功了拉 In the past, my team needed a lot of manpower to drill the horizontal drilling and pulling pipework. The labor intensity was large and the pulling pipe efficiency was very low. Deep hole drilling, pipe pulling time is drilling 5-6 times, or even 8 times, most of the drilling time spent in the pipe pulling process has become the main issue of horizontal drilling. Through the study of Chairman Mao’s works, cadres came to work at the scene, identified the major contradictions and designed them. Under the leadership of the party committee, the successful trial of the existing materials and scrap materials through trial production was completed
