我队曾协助益阳市自来水公司打吸水井。吸水井位于资江河中，水深、浪大、流速急，靠近主航道，水上钻探施工条件复杂。针对勘探场地这些不利条件，经多方研究，最后决定采用国产争光10型取样钻机（以下简称取样钻）进行水上钻探。由于采取了一些切实可行的具体措施，四天多就顺利完成了任务。一、具体措施1．河水浅的地段搭台钻进因为取样钻机体小，重量轻，所以只需要用普通的杉木条和松木板搭设钻台，钻台面积不宜过大、以
My team has helped Yiyang City Water Company to play suction wells. Suction wells located in the capital river, water depth, waves, rapid velocity, close to the main channel, water drilling complex construction conditions. In view of these unfavorable conditions of the exploration site, after much research, the final decision was made on the domestic drilling using the domestic Zhenguang 10 Sampling Drill (hereinafter referred to as the sampling drill). As a result of some practical and concrete measures taken, the task was completed in four days. First, the specific measures Because of the small size and light weight of the sample drilling rig, it is only necessary to set up the drilling rig with common fir and pine boards. The area of the drilling rig should not be too large to
