The upper water isolation strip 11, the lower water isolation strip 12 and the two side water isolation strips 13 jointly enclose a water collection area. By measuring the flow rate of the water collection area per unit time and combining it with the total area of the slope, the rainwater flow rate of the three-dimensional slope as a whole per unit time can be obtained; the top shape of the water storage tank 2 is adapted to the shape of the lower water isolation strip 12 and fits the bottom surface of the lower water isolation strip 12. A water permeable groove 121 communicating with the water storage tank 2 is opened on the lower water isolation strip 12. The rainwater flowing out of the water collection area can enter the water storage tank 2 through the water permeable groove 121 for collection; multiple measuring cylinders 3 are arranged at intervals in the width direction of the water storage tank 2 below the water storage tank 2. The measuring cylinders 3 are transparent cylinders and scales 31 are distributed on the measuring cylinders 3. A plurality of connecting pipes 21 are arranged at the bottom of the water storage tank 2. The plurality of connecting pipes 21 correspond to the multiple measuring cylinders 3 one by one. The plurality of connecting pipes 21 can simultaneously introduce the rainwater collected in the water storage tank 2 into the multiple measuring cylinders 3.

Then, the water blocking sheet 131 at the top end of the side water blocking strip 13 is pressed by the pressing member 4 on the upper water blocking strip 11, and the water blocking sheet 131 at the bottom end of the side water blocking strip 13 is pressed by the pressing member 4 on the water storage tank 2, which can prevent rainwater outside the frame 1 from entering the water blocking area and at the same time prevent the rainwater in the water blocking area from flowing out of the frame 1. Specifically, the pressing member 4 includes a pressing seat 41, a pressing sheet 42 is provided on the pressing seat 41, and a pressing screw 43 for driving the pressing sheet 42 to abut against the water blocking sheet 131.

Remove multiple measuring cylinders 3 from the slope surface and observe the collected rainwater volume. Calculate the total collection volume of multiple measuring cylinders 3 to obtain the rainwater volume per unit time in the water collection area. Combine with the total area of the slope to obtain the rainwater flow rate of the three-dimensional slope as a whole per unit time.
