1、工程概况1991年广西区渔业建港工程公司承建的企沙渔港码头扩建工程为混凝土方块重力式码头,位于企按渔港深水码头和冰厂码头之间,长135m,两个泊位,工程预算总造价105万元。码头基槽开挖分两步进行,首先由1.5m3的抓斗挖泥船经一个多月施工完成基槽方量约1万m3;此后由 1. Project Overview In 1991, the expansion project of the construction of Qisha Port built by Fishery Harbor Engineering Company of Guangxi District was a concrete block gravity wharf located at a distance of 135m long between the deep-water port of fishing port and the ice-wharf. The two berths, the project budget The total cost of 1.05 million yuan. Pier base trench excavation in two steps, first by the 1.5m3 grab dredger by more than a month to complete the construction of the foundation side of about 1 million m3; from
