Abstract

Three Gorges Project vertical ship lift is high-walled tower structure. According to the precision requirements of construction for concrete body and built-in embedded parts, the plane, elevation datum transmission and positioning measurement methods for embedded parts in construction survey of concrete and built-in embedded parts of Three Gorges Project ship lift tower were studied. The construction survey technologies, including zenith telescope planar cast point, electromagnetic distance measuring and cylindrical nut type positioning device with a sighting mark in center are applied to size-control measurement for concrete structure and positioning measurement for built-in embedded parts respectively. Through the statistical analysis on the measured data, the construction survey technology solutions for concrete construction of Three Gorges Project ship lift tower are proved to be reliable and feasible.
