In order to solve the problem of anti-abrasion and anti-seepage of concrete scroll case in Nierji Hydraulic Project,the technology is applied into this project.

This paper reports the hydrology examination work for Nierji hydraulic project river closure in 2001 in winter.

The main purposes of Nierji Hydraulic Project is flood control so as to supply water for living and industry,as well as agriculture and power generation,while considerations on improving the shipping condition and water environment are needed.

CAT fiber was added in the construction of hydraulic turbine concrete of snails shelly in powerhouse of Ni erji water conservancy project in order to improve the performance of split-resisting,imperviousness,anti-impulse and wear-resisting.

Ni erji water conservancy project as an important project constructed by the state is strictly managed according to the law of tender and bid and the correlational policy and statute.
