High-speed railway embankment anti-seepage structure using capillary isolation layer
The invention discloses a high-speed railway embankment anti-seepage structure using a capillary isolation layer. The capillary isolation layer is arranged between a foundation bed surface layer and a foundation bed bottom layer of an embankment; the capillary isolation layer comprises a fine aggregate layer, a three-cloth two-film layer and a coarse aggregate layer from top to bottom; the fine aggregate layer is composed of sandy soil, the coarse aggregate layer is composed of gravel and construction waste, and recycling of the construction waste is beneficial to efficient utilization of resources and sustainable development of the environment. The capillary isolation layer is simple in structure and low in cost, the anti-seepage effect of the capillary isolation layer can be brought into full play, permeation of rainwater to the foundation bed bottom layer of the high-speed railway embankment is effectively controlled, and therefore the purposes of controlling settlement of the high-speed railway embankment and maintaining long-term durability and stability of the embankment are achieved.
本发明公开了一种利用毛细隔离层的高速铁路路堤防渗结构，在路堤的基床表层与基床底层之间设置毛细隔离层；毛细隔离层自上而下为细骨料层、三布两膜以及粗骨料层；细骨料层由砂土组成，粗骨料层由碎石和建筑垃圾组成，建筑垃圾的回收使用有利于资源的高效利用以及环境的可持续发展。本发明结构简单且成本低廉，能充分发挥毛细隔离层的防渗效果，有效控制雨水对高速铁路路堤的基床底层的渗透，从而达到控制高速铁路路堤沉降，维持路堤的长期耐久性和稳定性的目的。
