Summary on the construction of sealing the roof of powerhouse of Fengtan hydropower station expansion works

in the construction of concrete in powerhouse of Ni erji water conservancy project.

Xiafu Hydraulic Complex has a powerhouse to accommodate bulb turbine generator units.

The Xiaoshan Hydropower Station consists of reinforced concrete face rockfill dam, bank spillway, diversion system and power house.

Based on the prototype and model vibration test results,in this paper the reasons of severe viˉbration of powerhouse generator floor in the high operating head region had been analyzed.

Improvements for turbine building baseslab design;

The concrete structure surrounding spiral case of the Three Gorges power station s powerhouse becomes one of the most complicated structures of the powerhouse for its queer geometric figuration.

In order to speed up construction schedule provided that construction quality is guaranteed,the 2nd stage concrete of the cone tube is changed to 1st stage concrete during powerhouse construction of Suzhi hydropower project.

3-D FE-IE model(3-D finite element and infinite element coupling model) for the hydropowerhouse in the Three Gorges Hydropower Project is set up in utilizing infinite element to model the characteristic of unbounded media.

Therefore,this paper takes an electronic factory building as an example,which analyzes the occupational risk factors of its production plants,power facilities,chemicals tank farm in detail,and then it sets forth a series of occupational safety measu.
