江阴玻璃钢船厂承担的千吨驳舱口盖试制任务,是1981年国家重点科研项目之一,经过长江干线千吨驳、杂货驳三年的实船试用,证明各项试验数据符合设计要求。不但本身重量轻,推动用力小,而且耐腐蚀,造型美观,有良好的水密性。这种舱口盖充分体现了玻璃钢轻质、高强的优越性,不但为长江货驳提供了比较实用的舱盖,也为玻璃钢的应用提供了新的途径。交通部长江船舶设计院设计的,以钢质骨架、玻璃钢盖板组成的混合结构,承受重量后,变形很小,外力消除即能恢复原状,并具有损坏后容易修复的优点。在使用中,能减轻船员的劳动强度和降低油布的损耗,并节约
The tens of tons of unloading hatch cover trial task undertaken by Jiangyin FRP Shipyard was one of the national key scientific research projects in 1981. After three years of actual ship trials of 1,000 tons of refutation on the Yangtze River Trunk Line and groceries, it was proved that the test data met the design requirements. Not only its own light weight, pushing force is small, but also corrosion-resistant, beautiful appearance, good watertightness. This kind of hatch cover fully embodies the advantages of lightweight and high-strength glass steel, not only provides a more practical hatch cover for the Yangtze River cargo barge, but also provides a new way for the application of fiberglass. The Yangtze River Ship Design Institute of the Ministry of Transport designed a hybrid structure consisting of a steel skeleton and a glass fiber reinforced plastic cover plate. After the weight is taken, the deformation is very small, and the external force can be restored to the original state, and it has the advantage of being easily repaired after being damaged. In use, can reduce the crew’s labor intensity and reduce the loss of tarpaulin, and save
