model article 1 of construction report: project construction report

Dear leader:

This project is based on the design of Jiaxing Water Resources and Hydropower Exploration and Design Institute and the design and requirements of Haiyan Water Conservancy Bureau, Qinshan Street and Vineyard Owner. After signing the contract on August 31th, it will enter the site on September 7th and be accepted on October 6th, with a total time of * * * lasting 45 days, and all the contents of the project will be completed, specifically. Data acquisition of pressurized pump house in the first station, control and protection of water pump, valve reform; Installation of automatic fertilizer adding system, pipeline reconstruction and canopy construction; Optical fiber laying and welding of the whole system, laying of power line, video signal line and video control line of the whole system; Simple decoration of the control room of the control center, installation of network cabinet, installation of operation desk, configuration of software and hardware of automatic control system, etc.

I. Overview

This project is located next to the North Tuanshi Factory in Qinshan Town, and there is a pressurized pumping station and two 31KW pumps near the river, one for use and one for standby, with frequency conversion control and automatic manual control. The original intake vacuum drainage tank is equipped with two manual gate valves, which has no water shortage protection function. The vineyard * * * is about 351 mu, and there are 16 manual valve wells (the depth of the wells is slightly higher than the ground level). All the work must be manually operated by people at the site. In order to meet the requirements of modern agriculture and landscaping irrigation, and achieve the purposes of scientific water use, improving labor productivity and increasing production and income, a set of automatic drip irrigation fertilization system is specially built. In this automatic control system, all data are transmitted to the monitoring center by optical fiber communication.
