西非马里共和国大小井配套工程施工技术

Construction Technology of Matching Engineering of Drilling Hole and Well in the Republic of Mali Western Africa

摘要:

西非的马里共和国是一个严重缺水的国家。结合在该国实施的147个大小井配套工程，从小井施工、大井施工、大小井贯通、消毒及抽水实验几个环节进行了阐述，并对施工中可能遇到的问题进行了分析，给出了解决方法。大小井配套工程在解决非洲缺水地区人畜饮水问题上不失为一种比较好的方法，值得推广。

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.
