摘要
伴随疏浚技术的快速发展,采用大型挖泥船直接开挖大体积风化岩已成为主要施工手段。以“电天牛”系列绞吸船为例,通过合理选用绞刀和绞刀齿、降低绞刀齿磨损、软化岩石等一系列措施,可有效提高船舶生产率、降低施工成本。与传统炸礁、清礁施工工艺相比,绞吸船开挖风化岩具有施工效率高、成本较低的优点。
With the rapid development of dredging technology,the direct excavation of large-scale weathered rock by large dredgers becomes the main means of construction.Taking the “Electricity-Tianniu” series cutter suction dredger as an example,through a series of measures,such as rational selection of cutter head and cutter tooth,reduction of cutter tooth wear and softening rock,the productivity of ships is effectively improved and construction cost is reduced.Comparing with the traditional reef blasting and reef clearing construction technology,the cutter suction dredger excavation of weathered rock has the advantages of high construction efficiency and low cost.
