在斯塔夫罗波尔斯克的边缘地区,暗管排水工程的施工都是采用半机械化明沟开挖的方法。生产实践观测表明暗排作用的实际效果常常低于设计要求,也就是地下水位仍高于设计标准。为了查明暗排效果不好的原因,在试区上进行了不同暗排结构对比方案的试验研究,方案中有通常采用的北高加索水利科研勘测设计院的设计结构型式和斯塔夫水利工程与土壤改良科研所改进的试验结构型式。
In Stavropolsk’s marginal area, the construction of concealed pipe drains is a method of excavation using semi-mechanized open ditches. Production practice observations show that the actual effect of an underbody arrangement is often lower than the design requirement, that is, the water table is still above design criteria. In order to find out the reason of the poor rowing effect, the experimental study on the contrast scheme of different dark row structures was carried out. The design scheme of the North Caucasus Water Resources Research Institute of Survey and Design, which is commonly used, Soil improvement research institutes to improve the experimental structure type.
