Construction Measurement Control of Square Vertical Shaft with Large Height Difference
The excavation section type of the cable elevator shaft for the civil engineering and metal structure installation of the TB hydropower station's water diversion and power generation system is rectangular,with the characteristics of small section size and large excavation depth.Its accuracy and reliability are directly related to the construction quality of the vertical shaft.In order to ensure that the excavation,lining shape,and embedded parts meet the design requirements,this article summarizes the application of small size and large height difference rectangular vertical shaft construction measurement technology and methods,and studies the measurement and control technology of the cable elevator vertical shaft in hydropower stations.
