| Abstract: | This paper mainly introduced applying construction technology of driling holes by the crawler, the usage of the precast long steel column and superfine cement grouting in the reinforcement of bearing capacity of the grouting pile. These methods successfuly solved problems of the schedule and cost increasing in the pile construction of artificial hole of 2.8m in diameter, of 30m in depth and of 4.8 m in expanding botom diameter and achieved good economic benefits. |
