Drainage pipe with replaceable filter element and filter element replacement method thereof
The invention discloses a drainage pipe with a replaceable filter element and a filter element replacement method thereof, and relates to the technical field of slope underground water drainage pipes, the drainage pipe comprises a porous pipe and a filter element, a plurality of water seepage holes are formed in the pipe wall of the porous pipe, one end of the porous pipe is a closed end, and the other end of the porous pipe is an open end; the filter element is inserted into the porous pipe and comprises a filter screen pipe, an inverted filter layer covering the surface of the filter screen pipe and a water injection pipe arranged in the filter screen pipe; the replacement method comprises the steps of segmenting the drainage pipe, performing finite element analysis to obtain a change curve of slope stability coefficients under different clogging and rainfall conditions, and determining whether the drainage pipe is replaced or not and a replacement time point according to the change curve. According to the invention, the structure of the drainage pipe is optimized, the calculation of the equivalent permeability coefficient of the soil body is improved in the analysis method, a filter element replacement method is further established based on the analysis of the stability coefficient of the side slope under different clogging conditions, the characteristics of the soil body are better met, and the analysis result is more real and reliable.
一种可更换滤芯的排水管及其滤芯更换方法，涉及边坡地下水排水管技术领域，排水管包括多孔管和滤芯，所述多孔管管壁设置有多个渗水孔，所述多孔管一端为封闭端且另一端为开口端；所述滤芯插接在所述多孔管内，所述滤芯包括滤网管、覆盖在所述滤网管表面的反滤层以及设置在所述滤网管内部的注水管；更换方法包括将排水管分段、有限元分析得到不同淤堵及降雨情况下边坡稳定系数的变化曲线、根据变化曲线确定排水管是否更换和更换时间点。本发明优化了排水管的结构，并在分析方法上针对土体等效渗透系数的计算做出了改进，进一步基于不同淤堵情况下边坡的稳定系数分析建立了滤芯的更换方法，更符合土体的特性，分析结果更真实可靠。
