What are the adverse effects of climatic conditions along Lanzhou-Xinjiang high-speed railway on high-speed railway construction?

The climate is continental, hot in summer and cold in winter, and the annual and daily temperature ranges greatly, which is not conducive to workers' construction;

Located inland, the annual precipitation is scarce, water resources are scarce, and it is difficult to guarantee the water for engineering construction and domestic use;

Winter is close to the wind source, with strong wind and many sandstorms in winter, which increases the construction difficulty and hinders the project progress.

Pay attention to the climatic conditions and answer from two aspects: temperature and precipitation.
