Studies On Tianjin Center Port Water Consumption Forecast And Pipes Desig Optimization

As a national key project, Central Fishing Port of Tianjin is an important carrier of a new oceanic economy development, which can promote urbanization of fishing area. In order to do water supply for Central Fishing Port well, the water supply network of Urban Area and Hangu District builded by predicting water consumption and making the design and construction of water-supply pipes and aqueduct.The paper basically grasped the scale and trend of water consumption in the planning period of Central Fishing Port. With making a reasonable plan, development and utilization of water resource, the appropriate water consumption can be safeguarded in the planning period, In addition, water can be maximum saved. On this basis, according to the position of the selected water supply source (JinBin Water Plant) and the Central Fishing Port, the possible crossing routes, the present situation of underground and ground constructions along the route, and combined with the present situation and the overall planning of Tianjin urban road system in 2020, the burying routes of the water pipeline from JinBin Water Plant to Central Fishing Port and the pipes of different sections determinate by making a comparison in term of technical economy. Then, taking the minimum annual cost of water pipes engineering as a goal, the economic diameter of pressure aqueduct determined using the traditional calculation method of the network economy. Finally, according to the results of optimal design of aqueduct, a set of practical construction plan proposed, which can provide the adequate and reliable water guarantee for the construction of Central Fishing Port.
