For a long time,with the rapid development of China's economy,along with the advancement of urbanization process,a large number of construction land is needed,on the one hand,the shortage of cultivated land resources,on the other hand,the construction land is occupied by a large number of cultivated land,and the land resources are increasingly scarce.All the provinces in the coastal areas are eager to solve the land demand of the urban development,especially the land demand of the coastal construction of the ports along the river.Reclamation is an important way to expand living space and production space.The main way to encircling the sea is to fill the mud and sand on the bottom to the scope of reclamation.The general construction machinery is dredger.At the same time,90%of China's foreign trade is completed by sea every year,and ports play an important role as a special hub.The top ten ports in the world have seven seats in our country.There are 34 million ton and more than 2300 ton berths of our country.There are five ports in the ring Bohai,the Yangtze River Delta,the southeast coast,the Pearl River Delta and the southwest coast.However,in the 18 thousand kilometers of the coastline,the number of real natural deepwater ports is very small,and all of them need to dredge the channel and dredge the berth.And the general construction machinery is also a dredger.The main types are winch suction type,chain bucket type,grab bucket type,rake suction type and suction type.The combination of sea reclamation and dredging channel is only done with the suction dredger,because the suction dredger not only has the advantages of low cost of engineering,but also the ship type can adapt to a variety of working conditions,especially in the dredging and reinforcement of the embankment,the reinforcement of dikes and other projects is only a suction dredger.To complete.Therefore,cutter suction dredgers play an important and irreplaceable role in dredging and dredging projects.hrough the study on the quota of Jiangsu water conservancy project design estimate(2017 Revised Edition)and the 2010 edition of Jiangsu water conservancy project budget quota on the quota of the dredging dredger in the dredging project,this paper analyzes the quota formulation and the quota group price factors,determines the influencing factors,constructs a new break even analysis model,and constructs the change of the total cost in the ship type.The relation between the total cost and the total square quantity when the distance is changed,the function diagram of the total cost and the total square of various ship forms at the same row distance is obtained,and the intersection point(i.e.the balance Square)is found out,the optimal cost point is obtained according to the data,the optimal cost points are connected in turn to form the optimal cost line,and finally the optimal cost distribution is made to find the project and the standard section at a certain row distance.In the case of known quantity,it is concluded that the lowest cost is the type of hull.According to the quota data,we can speculate the fixed variable and fixed cost of4500m~3/h Tian whale,and calculate the equilibrium square when the row spacing is 3.1km.Finally,two examples are used to verify the optimal cost distribution diagram.
