径流场作为水土流失监测中重要的设施,其制作形式、工艺、方法都直接或间接地决定了监测结果的精度和有效性。PVC-桩结构径流场采用防水、塑型方便的PVC材料与桩体利用软连接来制作水土流失监测径流场,具有试验结果精确、布设简单、成本低廉、不受地形限制等诸多特点,可广泛应用于公路、铁路等具有短期侵蚀背景、侵蚀强度监测需求的生态影响型建设工程。 As an important facility for soil erosion monitoring, the runoff field determines the accuracy and effectiveness of monitoring results, directly or indirectly, in the form, process and method of its production. The PVC-pile structure of radial flow field is made of waterproof and plastic PVC material and flexible pile to make the monitoring runoff field of soil and water loss by soft connection. It has many features such as accurate test results, simple layout, low cost and no terrain restriction. Applied to highway, railway and other short-term erosion background, erosion intensity monitoring needs of the ecological impact of construction projects.
