Device and method for collecting side slope water and soil loss under rainfall condition
The invention discloses a side slope water and soil loss collecting device and method under the rainfall condition. The collecting device comprises a side slope ditch, a plurality of rotational flow grit chambers communicated with the side slope ditch are arranged on the side of the side slope ditch, collecting barrels are arranged in the rotational flow grit chambers, and the edge openings of the collecting barrels are lower than the bottom of the side slope ditch; a water guide structure opposite to the rotational flow grit chamber is arranged in the side slope ditch, and/or a water passing structure extending to the underground is arranged on the rotational flow grit chamber. According to the collecting method, the collecting device is adopted, surface water flow or underground seepage water flows into the rotational flow grit chamber in the direction not facing the center of the rotational flow grit chamber, the water flow forms rotational flow in the collecting barrel and carries out sediment deposition, and the sediment deposition amount in the collecting barrel within a set time period is collected and measured. According to the invention, the water and soil loss amount caused by rainfall of the slope in a certain area can be measured, and the result is accurate.
本申请公开了一种降雨条件下边坡水土流失的收集装置及收集方法。该收集装置包括边坡水沟，边坡水沟的边侧设置若干与边坡水沟连通的旋流沉砂池，旋流沉砂池内设有收集桶，收集桶沿口低于边坡水沟底部；边坡水沟内设有与旋流沉砂池相对的导水结构，和/或旋流沉砂池上设有伸至地下的通水结构。该收集方法采用上述的收集装置：地表水流或地下渗水沿非朝向旋流沉砂池中心方向流入旋流沉砂池中，水流在收集桶内形成旋流并进行泥沙沉积，收集并测量设定时间段内收集桶内泥沙沉积量。本申请可测量一定区域内边坡因降雨引起的水土流失量，且结果较为准确。
