在简易水文地质工作中,有一些值得讨论研究的问题,本文仅就以下三个问题提出讨论意见: 一、动水位观测的效果值得怀疑 传统的简易水文地质工作中的主要部分——动水位观测和冲洗液消耗量观测,在很多地区的具体水文地质条件和施工条件下,事倍功半。同其它许多工作方法一样,它们也有一定的适用条件。动水位和冲洗液消耗量观测的“理想条件”是:1.清水钻进;2.钻孔施工过程中孔内不发生自然造浆;3.每次提钻后,孔底不存在较厚的岩粉;4.钻孔施工过程
In simple hydrogeological work, there are some issues that are worth discussing. This article only discusses the following three issues: First, the effect of dynamic water level observation is questionable The main part of the traditional simple hydrogeological work - the dynamic water level observation And flushing fluid consumption observations, in many parts of the specific hydrogeological conditions and construction conditions, less effective. Like many other methods of work, they also have certain conditions. The “ideal conditions” for the observation of water level and rinsing fluid consumption are as follows: 1. water drilling; 2. no natural slurrying occurs in the hole during drilling; 3. no thicker holes exist at the bottom of the hole after each drilling Rock powder; 4. Drilling construction process
