Feasibility Study On Renovation Project Of Large Pumping Station Of Jingdian First Phas

The Jingdian Irrigation Area is one of the important commodity grain bases in Gansu province.The Jingdian project is an important guarantee for the survival and development of the population,the increase of the farmers'income and the enrichment of the farmers.It is an important infrastructure for the development of the local agriculture and the rural economy,and plays an irreplaceable basic role in the economic and social development of the irrigated area.It is of great significance for the sustainable development of the irrigation area and the construction of a new socialist countryside to make a good job of the management and construction of the Jingdian project and make it full benefit.On the basis of summarizing the status quo of the development of the first phase of the project,the feasibility and necessity of the project implementation are discussed.The task of this renewal and transformation is put forward according to the safety appraisal report of the large-scale pumping station of Jingtai Sichuan electric power pumping station,the content and scale of the construction are determined,and the layout of the project is arranged according to the relevant design specifications.As well as the design of the building,the construction organization design and estimation of investment are compiled,and the engineering management measures are formulated,and the economic benefits of the project are evaluated.The main results are as follows:(1)To update the project to meet the requirements of the energy consumption for the standard,the project can improve the safety and reliability of the project operation and the level of operation and management after the completion of the project,so that the irrigation quality of the irrigated farmland is greatly improved,which provides sufficient and reliable water for the construction of drinking water,town and industry,irrigation district and the ecological environment on the periphery of the irrigation district.The source will promote the comprehensive and sustainable development of the society and economy in irrigation districts.(2)The renovation project is mature,there are plenty of natural materials in the project area,which conforms to the overall goal of the national social and economic development and the improvement of the ecological environment.The construction of the project is feasible.(3)The project is designed to replace the 3 pipes of 1~#~4~#town pier of the total dry two pump station,6~#town pier to the pool of 2~#to 4~#pipe,the demolition and reconstruction of the town and the buttress,the transformation of the pipe groove and the lining,the replacement of the 1~#pipeline between the 1~#pier and the water pool,the demolition and reconstruction of the town and the buttress,and the total dry two pumping station,5~#town pier to the water pool,and the newly repaired Panshan road and repair plate in the outlet pool.Mountain road road,general dry three pump station 3~#town pier to6~#pier pipe replacement;West stem two pump station block bridge reconstruction;total dry two pump station,West dry two pump station management room and living facilities transformation.(4)After the completion of the project,the irrigation area will be improved by 11thousand mu,the grain production capacity is increased by 840 thousand kg,the production capacity of economic crops is increased by 2 million 125 thousand and 200 kg,and the production capacity of herbage is increased by 144 thousand kg.Annual output value increased by 3 million 8 thousand and 900 yuan and annual net profit of 2 million256 thousand and 700 yuan.Annual water supply to the irrigation area and surrounding area is 400 thousand m~3,water fee is 0.35 yuan/m~3,and annual water fee increase is 12thousand yuan.After the transformation of pumping station project,the efficiency of pumping station is increased,the energy consumption is reduced,and the annual electricity saving is 3 million 200 thousand kW·h,and the electricity tariff is saved by 160 thousand yuan.(5)The drinking water of human and livestock in the rural areas is provided 1 million230 thousand m~3 per year,providing 3 million 30 thousand m~3 for urban and industrial water use,and providing 2 million 150 thousand m~3for ecological environment construction water to the irrigated area and its surrounding area,in order to maintain the economic development of the irrigation area,improve the living water of the people and improve the local ecological environment to provide reliable water source.(6)The internal income rate of the project is 8.68%,more than the social discount rate of 8%,the net present value of the economy is 1 million 250 thousand yuan more than0,the cost of economic benefit is more than 1,the index is superior and the economic benefit is remarkable.(7)After the implementation of the renovation project,the utilization rate of water reached 63.8%and the irrigation guarantee rate reached more than 75%,thus promoting stable production and high yield of food economy crops and increasing farmers'income steadily,At the same time,prompting the past barren land appeared a vibrant scene,forming a green barrier,can effectively inhibit the harm of wind and sand,Therefore,some ecological benefits are generated?...
