Water lifting and wind erosion prevention method based on clay pressure injection in arid valley area
The invention discloses a water lifting and wind erosion prevention method based on clay pressure injection in an arid valley area. A plurality of clay columns are injected in the surface layer position of a sand surface at the bottom of a slope 1 of the arid valley area in a pressure mode; setting and implementing clay pressure injection parameters according to the following four key technical links: determining the design height of a clay soil column; clay soil column particle size grading is designed corresponding to the design height of the clay soil column; determining the wetting radius of the clay soil column; and determining the laying density of the clay columns. The innate advantage that water in the river valley area is sufficient is fully utilized, based on the capillary water rising effect of clay, under the condition that no external power is applied, water in the river valley is transferred to a surface layer dry soil layer, the surface layer soil is wetted, and wind erosion is reduced. The sustainability is high; the construction principle is mature, and the practical operability is high; materials can be obtained locally, and the cost is low. The wind erosion problem in the river valley area can be completely solved.
本发明公开了一种干旱河谷区基于黏土压注的提水防风蚀方法，在干旱河谷区坡面1底部的沙面表层位置压注多根黏土土柱；并根据以下4个关键技术环节拟定实施黏土压注参数：确定黏土土柱设计高度；对应黏土土柱设计高度设计黏土土柱粒径配级；确定黏土土柱湿润半径；确定黏土土柱布设密度。充分利用河谷区水分充足这一先天优势，基于粘土的毛细水上升作用，在不施加任何外部动力的情况下，将河谷中水分运移到表层干土层，使表层土湿润降低风蚀。可持续性强；施工原理成熟，实操性强；材料可就地取材，成本低。可以完全解决河谷区风蚀问题。
