摘要
针对上游法筑坝坝体浸润线高、危害大、降深难的问题，采用水平孔—竖直袋状砂井联合自流排渗新技术进行排渗。该方法不仅排渗水量大，浸润线降低幅度大，不需动力和维护，而且施工简单快捷，投资费用低，适用于各类尾矿坝浸润线的降深。
In consideration of the problems of high water table level,great danger and difficulty in table lowering existing in the dam body constructed by up stream method,the new gravity flowing technology of the combination of horizontal holes—vertical pocket type sand wells was used for filtrate drainage.This method is not only characterised by large volume of drainaged infiltrate,great lowering of water table level and needing no power and maintenace,but also has the advantages of simple and rapid construction and small investment.As a result,it is suitable for the water table level lowering of various tailings dams.
