[0002] Floral drainage boards are made of polystyrene or polyethylene plastic base plates, stamped to form conical protrusions or reinforcing ribs (or hollow cylindrical porous shapes). These drainage boards can quickly and effectively drain rainwater, significantly reducing or even eliminating the hydrostatic pressure on the waterproof layer. This active water-guiding principle achieves an active waterproofing effect.

[0023] As an optional technical solution of this utility model, a water inlet balance pipe 7 is fixedly connected to the center of one side of the test cylinder 5, a drainage balance pipe 18 is fixedly connected to the center of the side of the sealing cover 17 away from the test support platform 21, a second overflow plate 23 is fixedly connected to the center of the top of the inner wall of the water inlet balance pipe 7, a first overflow plate 23 is fixedly connected to the center of the top of the inner wall of the drainage balance pipe 18, a drain valve 19 is fixedly connected to the center of the top of one side of the drainage balance pipe 18, and a water inlet is fixedly connected to the center of the top of one side of the water inlet balance pipe 7.

[0024] As an optional technical solution of this utility model, a water storage tank 20 is provided on the inner wall of the frame support 1.

[0027] The following steps are required when using this longitudinal water flow measuring instrument for flower drainage boards:

[0028] 1) The transmission screw 15 is rotated by the geared motor 13, which can drive the sliding support plate 16 to slide towards the geared motor 13, thereby opening the sealing cover 17 and allowing the test support table 21 to pull out the test cylinder 5.

[0029] 2) Then place the flower drainage board onto the top surface of the testing support platform 21;

[0030] 3) Then, water is pumped into the water inlet balance pipe 7 by the water inlet pump 24, and then injected into the test cylinder 5. Water is then injected into the test cylinder 5 until the second overflow plate 23 overflows, so that the test cylinder 5 is filled with water.

[0031] 4) Then open the drain valve 19 to allow water to drain out. At this time, the water level difference between the two ends of the drain plate is exactly 20cm, the hydraulic gradient is 0.5, and check if the pressure is 350kpa. After everything meets the requirements, use a measuring cylinder to take water at the overflow outlet 3 to measure the water flow and measure the water temperature. Repeat the water flow measurement after 6 hours. When the relative error between the two is less than 2%, the latter water flow is taken as the test value of the water flow of the drain plate.

[0032] In summary, by rotating the transmission screw 15 driven by the reduction motor 13, the sliding support plate 16 can slide towards the side of the reduction motor 13, thereby opening the sealing cover 17. This allows the test support platform 21 to be pulled out of the test cylinder 5, facilitating the placement and removal of the drainage plate for testing. After placement, the rotation of the transmission screw 15 causes the sealing cover 17 to cover the sealing silicone ring 11, achieving a seal on the test cylinder 5. This allows for quick placement and removal of the test plate, improving testing efficiency. By setting up the test support platform 21, the test cylinder 5 can be pushed in during testing to fill the space, thereby improving the efficiency of increasing water pressure inside the test cylinder 5 and achieving water balance more quickly, thus improving testing efficiency.
