我局工程队将300吨方驳改装成水下粗、细平工作船。船上装有可拆装的分节组合式细平专用刮槽(尺度为6～9.5米),设有吊杆,供升降刮槽用,船首设有碎石漏斗架横移道车轮,可左右移动供料,并挂有象鼻式分节漏斗;船尾设有粗、细平所需的二片石钢筋笼,以控制补抛片石的准确性。粗、细平仍由潜水员用横向刮道做检查,先粗平,再细平。利用该船粗、细平,提高工效3倍。
Our engineering team 300 tons of barge converted into underwater rough, fine workboat. The boat is equipped with a detachable sub-section combination of fine special scraping groove (scale of 6 ~ 9.5 meters), with a boom for the lifting scraper groove, the head with gravel tractor cross-track wheel, can be left and right Mobile feed, and hung with a triceratopic segmented funnel; stern with coarse, fine required two pieces of stone reinforced cage, to control the accuracy of make-up tablets stone. Coarse, thin still by the diver to do horizontal scraping inspection, the first coarse, then fine. The use of the ship rough, fine, improve work efficiency 3 times.
