This paper introduces in detail the electrification project from the HongLiuhe River to Yandun Hami region in Xinjiang, analyzes and summarizes from the construction point of view construction control technology of bridge piers at the alpine region with strong winds and low temperature environment. Through the control of key technologies like the erection of scaffolding, the pier insulation, moisture shed erection, concrete quality assurance control, the engineering quality of the piers is ensured in condition with strong winds and low temperature. It provides reference for construction continuous con- struction of concrete and engineering rescue with strong winds, and low temperatures in alpine regions.
