本处所谓“压榨”,系指通过不同的压力将天然沉积物中的孔隙溶液挤出来,以确定其成分地化性质.对于岩土中孔隙溶液的水质和推的研究,在水文地质、工程地质、水文地球化学、环境地质等方面均具有特殊的意义.该仪器81年由我院水文系研制(委托有关厂家负责制造),为气压—活塞两用三联式密封型压榨仪,扰动土和原状土均可试压.仪器操作简单,退样时仍借助于气压,使用方便.一、主要部件和技术性能
As used herein, “squeezing” refers to the extrusion of pore solutions in natural sediments by different pressures to determine their compositional geochemical properties.For the study of pore water quality and pushing in geotechnical engineering, in hydrogeology, engineering Geology, hydrogeochemistry, environmental geology, etc. The instrument was developed by our hydrology department in 1981 (commissioned by the manufacturers responsible for manufacturing), for the pressure - piston dual-use triple sealed press, disturbance of soil and The undisturbed soil can be pressure test. The instrument is simple, air pressure is still used when the sample is withdrawn, easy to use. First, the main components and technical performance
