| Abstract: | The Republic of Mali in the Western Africa is a serious water-shortage country.This article introduces the technology of smaller-diameter outlet well（forage） drilling and larger-diameter storage well（puit citerne） drilling,connection of outlet and storage wells,disinfections and water pumping experiment according to the 147 wells matching engineering in Mali and analyzed the construction problems possible encountered with the solutions.The matching engineering of smaller-diameter outlet well and larger-diameter storage well is a good way to solve the people and livestock drinking water difficulty for water-shortage area in Africa,which is worth popularizing. |
