扬州地区638.8公里航道的疏浚任务,大部分由两艘60米~3绞吸式挖泥船组承担,因受航道条件及抛泥区的限制,其输泥管道搬迁频繁。过去使用10英寸钢管时,因重量大,敷设困难,相继发生多起碰伤、砸伤事故。 1986年初,在省工程局的支持下,与常州增强塑料厂合作,试验用该厂生产的高密
Most dredging operations in the 638.8km waterway in Yangzhou are mostly undertaken by two 60m ~ 3 cutter suction dredgers, which are relocated frequently due to the restriction of shipping conditions and disposal areas. In the past when using 10-inch steel pipe, due to heavy weight, laying difficulties, have occurred more than bumps, injured accident. In early 1986, with the support of the Provincial Engineering Bureau, and Changzhou reinforced plastic factory cooperation, test the plant used to produce high-density
