Embodiment 1

[0023] see figure 1 with figure 2 , a kind of simulated experimental device for roof greening rainwater stagnation and purification of the present invention is composed of simulated roof greening device 1, slope brick bearing platform device 2 and rainwater runoff collecting device 3 three parts.

[0024] The simulated roof greening device 1 is composed of an HDPE box 11 with an internal dimension of 685 mm in length, 525 mm in width and 390 mm in height, and inside the HDPE box 11, 30 mm high root-proof, breathable, storage and drainage boards are sequentially laid from bottom to top. 12. The mass per unit area is 150g / m 2 Geotextile 13, matrix layer 14 and vegetation layer 15, described geotextile 13 can superpose multi-layer according to specific experimental design requirements, to achieve expected experimental effect, described matrix layer 14 can be configured and laid according to specific experimental design requirements, The maximum laying thickness is about 310mm,...

Embodiment 2

[0028] The main structure of this embodiment is the same as that of Embodiment 1, the difference is that the PVC drainage pipe is a three-stage structure (such as image 3 shown), are respectively a PVC drainage pipe 311 with an inner diameter of 30mm and a length of 100mm, a PVC drainage pipe 312 with an inner diameter of 30mm and a length of 130mm, and a PVC two-way adapter pipe 313 with an inner diameter slightly larger than 30mm. The PVC drainage pipe 311 It is connected with the PVC drain pipe 312 by the PVC two-way adapter pipe 313, and is bonded with the special hard plastic PVC adhesive for water supply.

Abstract

The invention discloses a roof greening simulation experiment device comprising a simulation roof greening device, a bearing table device and a rainwater runoff collection device; the simulation roof greening device comprises a low-pressure polyethylene box; an anti-root filtering water storage and drainage layer, a base material layer and a vegetation layer are sequentially laid in the low-pressure polyethylene box from bottom to top; the bearing table device is used for bearing the simulation roof greening device; the rainwater runoff collection device comprises a drainage pipe and a sampling bottle connected with the drainage pipe; drained water enters the sampling bottle through the drainage pipe. The device is easy to assemble and move and can be specially applied to various roof greening simulation experiments, so that experiments are more flexible and are not limited by time, space and weather changes. The device not only can simulate flat roofs, but also can simulate slope roofs of different gradients.

Description

technical field [0001] The invention belongs to the technical field of roof greening and relates to a roof greening simulation experiment device which can be used for rainwater stagnation, runoff regularity and pollutant purification effect analysis. Background technique [0002] With the intensification of urbanization, the area of ​​urban impermeable underlying surfaces is on the rise, causing problems such as urban heat island effect, flood disasters, and water pollution to intensify. As the "fifth facade" of the city, the urban roof accounts for about 30% of the hard surface of the entire city. Therefore, since the concept of green roofs appeared in Germany at the end of the 19th century, this technology has gradually been valued and widely applied by countries all over the world. At present, countries around the world have carried out a series of roof greening research and application work. In the simulation experiment of roof greening, it is often necessary to establ...
