Analysis and simulation of the formation mechanism of chemical clogging in geotextile-encased hydraulic piezometer tubes
摘要
Abstract
To address the issue of chemical clogging in geotextile-encased hydraulic piezometer tubes,a comprehensive analy-sis was conducted on the structural characteristics of the permeable section of the piezometer tube and the function of the filter body.Combining factors such as the hydration of concrete,chemical reactions of minerals in soil layers,water flow conditions,and the material properties of geotextiles,the crystallization and deposition mechanisms leading to chemical clogging were ex-plored in depth.Based on existing research,a design concept for an indoor experimental device was proposed.The design con-cept of this device allows experimental simulation that considers the structural characteristics of the geotextile itself,the effects of chemical substances,and actual operating conditions,providing a reference for the prevention and mitigation of chemical clogging in geotextile-encased hydraulic piezometer tubes.关键词
