Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] see figure 1 , 2 , The test device of the present invention comprises a bed surface frame 1, a water barrier 2, a drainage groove 3, a drainage plate 4, an iron support 5 with a height of 60 cm, and an inclination adjustment device 6 installed at the bottom of the support. 3 rows of diameters are 2 centimeters of drainage holes on the water baffle 2, so that the soil flow in the horizontal direction in the soil layer can flow into the drainage groove through the water baffle. Drainage tank 3 is equipped with a top cover, which is used to prevent rainwater from directly falling into the drainage tank, which will affect the test results. The height of the inclination adjustment device 6 of each foot of the support 5 can be adjusted to level or adjust the inclination angle of the bed surface to ensure that the water flows into the drain...

Abstract

The invention discloses a testing device for detecting the closure and peak regulating effects of a green roof. The testing device comprises a testing bed face and a support. The testing bed face comprises a bed face frame. The bed face frame is divided by a water stopping plate into a left side and a right side, a water draining groove is formed in one side, and a water draining plate is laid on the other side; a filtering layer, a soil layer and a plant layer are sequentially arranged on the water draining plate, a plurality of water draining holes are formed in the water stopping plate and used for leading water into the water draining groove, a top cover is arranged at the upper portion of the water draining groove, a water outlet is formed in the water draining groove, drained water is led into a water collecting container through a water draining pipe, and the water draining plate also leads drained water into the water collecting container; the testing device also comprises a comprehensive detection analysis system. The testing device can be used for simulating the closure effect under the condition that an actual roof is transformed into a green roof, quantitative analysis is carried out, the influence of other factors on the testing result is eliminated, and the basis is provided for formulating a sponge-city development scheme. The testing device is low in cost, convenient to assemble and disassemble, high in operability and wide in application range.

Description

technical field [0001] The invention relates to the field of urban hydrology and flood control, in particular to a test device for detecting the effect of peak regulation and interception of green roofs. Background technique [0002] In recent years, there have been frequent reports of waterlogging disasters across the country, and the concept of sponge cities has been vigorously promoted across the country. At present, the roofs of urban buildings in my country account for about 40%-50% of the urban impermeable underlying surfaces, and the rainwater runoff of urban building roofs should be well controlled. It is of great significance to urban stormwater management and disaster prevention and mitigation. In recent years, green roofs have been widely regarded as a technology to solve the problem of stormwater regulation in complex cities. As a technology that can effectively intercept rainwater and carry out renovation at a reasonable cost, green roof has great development po...
