鼠道排水是治理渍害的有效途径

Mole Drainage——An Effective Way for Control of Waterlogging Damage

鼠道虽比暗管的排水效果差些,寿命短些,但施工方便,投资少,见效快,特别值得在南方粘质土地区大力推广应用。文章介绍了鼠道排水的原理和适用条件;以大量的试验数据为根据,证明了鼠道排水的治渍效果;根据不同情况,确定鼠道的合理布局。

Comparing with the underground pipe drainage. the mole drainage has shortcomings of lower drainage effects and short using life, but has many advantages, such as easy construction, Jess capital input and quick functioning,Therefore,it is worth for spreading and application in the clay soil region of South China. This paper presents the principles and applied condiment of mole drainage. The waterlogging damagecontrol effects of mole drainage have been proved by a large number of experiment data. The reasonable spacing of mole drains has been determined in many cases.
