Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is:

[0055] see figure 1 , In this embodiment, the drainage layer 60 is provided with drainage pipes (not shown in the figure) for discharging liquid. By adopting the above solution, it is convenient for excess liquid flowing into the storage and drainage layer 60 to be discharged from the drainage pipe in a timely, effective and reliable manner. In addition, the risk of liquid penetrating from the storage and drainage layer 60 to the structural layer 30 can be effectively reduced, and the waterproof performance of the green roof can be improved. In addition, it is also convenient for the user to quickly and conveniently install the drainage layer 60 according to the discharge position of the drainage pipe.

Abstract

The invention relates to the technical field of noise control, and provides a green roof and a building wherein the green roof comprises a soil layer, a low-frequency sound absorption structural layer and a structural layer which are arranged in sequence; the low-frequency sound absorption structural layer comprises a plurality of resonance structures which are arranged at intervals and extend in the thickness direction of the low-frequency sound absorption structural layer, and sound channels extending in the thickness direction of the low-frequency sound absorption structural layer are formed between the adjacent resonance structures. Each resonance structure is provided with at least one resonance cavity and at least one resonance neck enabling the resonance cavity to be communicated with the adjacent sound channel, and in the thickness direction of the low-frequency sound absorption structural layer, the cross section size of the resonance cavity is larger than that of the resonance neck. According to the green roof, medium-high frequency sound wave signals are effectively attenuated through the soil layer, low-frequency sound wave signals are effectively attenuated through the low-frequency sound absorption structural layer, attenuation of urban noise within a wide frequency range can be achieved, and the sound absorption and noise reduction performance of the green roof is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of noise control, in particular to a green roof and a building. Background technique [0002] Green roofs are one of the important structures for building green, low-carbon and healthy buildings. They can effectively improve the urban ecological environment, reduce building energy consumption, reduce flood disasters, create a good visual environment, and so on. However, the existing green roofs have poor sound absorption and noise reduction performance, especially the inability to effectively reduce traffic noise and multiple reflection noise in narrow streets, making residents vulnerable to noise interference and exhausted physically and mentally. Contents of the invention [0003] The purpose of the present invention is to provide a green roof to solve the problem of poor sound absorption and noise reduction performance existing in the existing green roof. [0004] In order to achieve the above object, ...
