| Abstract: | According to the characteristic of Qinghai-Tibet Plateau, the paper researches on the bore bottling pile and the change process of surrounding ground temperature, and summarizes the change rule of concrete temperature and ground temperature, which can guide the choosing of antifreezing measure and concrete mixing material temperature. Then it analyses the inftuence of concrete construction material and construction method on the back freezing law of bore bottling pile, and introduces the performance of drilling machine, drilling efficiency and concrete bottling craft. |
