Abstract:
In allusion to the problem of little water yield and more easy blocking up using the traditional construction well technology for the thin thickness and fine particle micro-confined aquifer in Suzhou-Wuxi-Changzhou area,this paper studys the micro-confined groundwater mining engineering and technique by the large-diameter well,daughter-parent well and arrangement well. Taking the three demonstration projects of Wutang in Changzhou,Tongli in Wujiang and Huangdai in Xiangcheng district of Suzhou as examples,we study and design the planar structure,dig a well structure and construction technology of the large-diameter well,daughter-parent well and arrangement well,and evaluates the water- well yield and changes in water quality under the mining technology. According to test results and hydrogeological conditions of the micro-confined groundwater,we conduct the mining technlogy appropriate zoning for the micro-confined aquifer in Suzhou-Wuxi-Changzhou,the zoning results have guidance significance to the mirco-confined aquifer mining technlogy planning.
