It produces little settlements at the bottom, less disturbance and erosion of mud to the walls. It provides a high rate of quality boreholes and meets requirements of various foundation piles.

孔底沉渣少，孔壁受泥浆影响和冲刷小，钻孔质量优秀率高，能够满足各种类型的基桩要求。

Moreover, the drilling process needs to be refined so that the deeper aquifers are not poisoned by arsenic-bearing water trickling down from the shallow aquifers through the boreholes themselves.

还有，钻孔的过程必须要改良，较浅含水层中的砷才不会经由凿孔向下蔓延，进而污染了较深的含水层。
