RUNOFF DIVISION AND COLLECTION APPARATUS FOR WATER EROSION MONITORING PLOT

摘要

Disclosed is a runoff division and collection apparatus for a water erosion monitoring plot. The apparatus comprises a collection cylinder and one or more division cylinders, the division cylinders being successively connected in series, wherein a head-end division cylinder is connected to runoff converging on a plot, and a tail-end division cylinder is connected to the collection cylinder. According to the runoff division and collection apparatus for a water erosion monitoring plot in the present invention, the cylinder is made of a high-strength anticorrosive alloy material and is cylindrical, and has an inner diameter of 1 m, such that the problem of a dead corner existing inside the cylinder is prevented relatively well; and the process of sampling is simpler, and a discharge port is reserved at the bottom of the cylinder, such that cleaning is easier. A stabilization grating is arranged inside the division cylinder, such that in the case of a large amount of rainfall, the difference in multi-hole division caused by the instability of flow can be effectively prevented, thereby improving the quality of division and the accuracy of observation and ensuring the uniformity of the water flow rate. Division holes have uniform diameters and are uniformly distributed on the same level, such that the accuracy of division is higher. A detachable stirring apparatus can realize rapid and easy stirring of a sample, such that the accuracy of sampling can be effectively improved.
