Technical Field

[0001] This utility model belongs to the technical field of soil and water conservation monitoring devices, specifically relating to a prefabricated runoff plot. Background Technology

[0002] In soil and water conservation monitoring, runoff plots are facilities used to quantitatively observe soil erosion. During the monitoring process, by observing data such as runoff volume and sediment content generated by rainfall in the runoff plots, we can understand and assess the degree of impact of different land use types, slopes, slope lengths, and slope aspects on soil erosion.

[0003] Existing runoff plots generally consist of embankments and catchment facilities. The embankments are used to clearly define the boundaries of the runoff plot, ensuring that all studies are conducted within this specific area. The area inside the embankments is the catchment area, and the catchment facilities, such as drainage ditches and catchment channels, are used to collect the water flowing out of the catchment area for measurement and analysis.

[0004] Traditionally, the embankments of runoff areas are formed by brick masonry and cement plastering. In order to ensure the stability of the embankments, it is necessary to excavate foundation trenches of a certain size and depth during construction, and then compact and backfill or masonry them as the foundation of the embankments to ensure the stability of the runoff area embankments. Currently, this construction method is slow, resulting in a long construction cycle for runoff areas. Utility Model Content
