High Precision Measurement of Metal Structure Installation in Hydropower Stations
The installation work of the metal structure of the Longpankar Hydropower Station mainly includes four radial gates in the overflow dam section,three supporting discharge gates at the bottom of the spillway dam section,and four water inlets in the plant inlet dam section.The installation measurement is mainly carried out on metal structures such as the radial gate of the overflow dam section,the steel lining of the spillway bottom hole and its working gate slot bottom sill,the pressure pipeline of the factory inlet and its maintenance gate slot bottom sill.High precision measurement methods are used to control the measurement accuracy and ensure construction quality.
