Application Research On Key Construction Technology Of Underwater Leveling Bar In Dredging Engineering

In dredging engineering high points are remained after dredger dredge sea bed,which is very common quality problem. Lower efficiency and higher cost are mostdifficult problems which always make the contractor headache at the last sweepingstep of construction. If sweeping can not be completed efficiently, not only the projectprogress will be suspended but also all expected profit of project will be devoured. Toachieve sustainable development, any dredging enterprise is aspiring to complete theproject with the way of Energy-saving, cost-reduction and efficiency-increasing.Developing the new sweeping equipment with higher efficiency and lower cost is tobe more and more important thing focused by dredging contractor.What we discuss is an underwater leveling bar which is specially used indredging engineering, while the key construction skills of the equipment is to bestudied integrated in this paper. At the first chapter, development trend of dredgingengineering and existed common quality problems of construction were analyzed sothat we can easily understand the background of the underwater leveling bar arising.Then the designing concept, structural style and assembling mode were clearlyrecommended as well as application scope, allowable operation condition and variouspreparation conditions of construction. According to experience summarized frompractice, we comprehensively stated the construction procedure, operation key points,and key factors of quality control and. Through studied the application of the levelingbar in three actual project cases, the economic benefits and social results were detailedanalyzed. High efficiency, low cost and environmental is its special superiority. It issignificantly to continue the study of the underwater leveling bar and its constructionkey technology for the dredging enterprise achieving sustainable development andincreasing the competence.
