一、前言地下水化学成分的究研乃是水交地質工作主要项目之一,而水样采取工具的优劣将直接影响地下水化学成分的研究,尤其是水中气体成分及一定深度水化学成分的研究,这对采取水样的工具应有较高的要求。目前野外实际工作中所使用采取水样的仪器,往往较为笨重,如:“地下水的物理性質和化学成分”(普里克朗斯基等著)一书中所介绍的彷水深测量器和定深取水器,前者除实用及设备麻烦外,还不能往深处取样。而后者则较为笨重,仅据重即达数公斤,且不适于口径较小的占孔中取水。另外较为轻便的西蒙诺夫取水,器刖易漏水,而使用时由于重经和器身猛烈投入鑽孔中,势必搅动了原水柱,或多或少的混杂了上下水层的水化学成分。其次,直接采用瓶子取水样 I. INTRODUCTION Research into the chemical composition of groundwater is one of the major projects in the field of hydraulics and geology, and the merits and demerits of tools for water samples will directly affect the research on the chemical composition of groundwater, especially the study on the composition of gas in water and certain depth of hydration , Which should have higher requirements for water sampling tools. Presently, the instruments used to take water samples in actual field work are often cumbersome, such as the depth-of-water measuring instruments described in Depth of Physical Properties and Chemical Compositions of Groundwater (Pricklyski et al.), Water, the former in addition to practical and equipment trouble, but also can not go deep sampling. While the latter is more bulky, weighing only a few kilograms, and is not suitable for smaller caliber hole taking water. In addition, the more convenient simeonov draws water and the device is easy to leak. However, due to the heavy and heavy body drilling, it is bound to agitate the original water column, more or less mixed with the water chemical composition of the upper and lower water. Second, direct use of the bottle to take water samples
