Total investment of ancient water conservancy project construction

This project is 0/58km away from Linfen City, Shanxi Province, 252km away from Taiyuan City, 252km away from Yan 'an City, Shaanxi Province and 439km away from xi City. It is necessary to build a digital microwave or optical cable communication line from Guxian to Linfen or Yan 'an, and connect it with the Yellow River special communication network and public telecommunications.

In the initial stage of construction diversion, it is planned to adopt the diversion mode of one-time interception and tunnel diversion, and it is planned to arrange two diversion tunnels in parallel on one bank. The structure type of earth-rock cofferdam is preliminarily selected, with loam core wall as seepage control and high-pressure shotcrete cutoff wall as foundation. The top elevation of upstream cofferdam is 5 19.50m, the top elevation of downstream cofferdam is 467.50m, the top width is 10.0m, and the slope ratio of upstream and downstream cofferdam is 1: 1.75.

The material transfer station of this project is planned to be located in Linfen City, with the total length of external traffic roads164km, of which18km needs to be built or rebuilt. A low-speed highway and an expressway are arranged on the left and right banks of the site, with a total length of 5 1.7km, in which the traffic tunnel is 650 meters long and the pier of the Yellow River Highway is 400 meters long. The total construction period of the left and right bank dam pulling scheme is 9 years, of which the static preparation period of the linear construction period is half a year, the main project construction is 8 years, the completion period is 6 months, and the preparation period is 2.5 years.

The budget price of main building materials is calculated according to the price in the second quarter of 2003, and the annual price index for calculating the price reserve is tentatively set at 0%. The main results of sub-investment estimation are as follows:
