Environmentally-friendly water-saving type root infiltrating irrigation device used for light greening

Abstract

The invention relates to an environmentally-friendly water-saving type root infiltrating irrigation device used for light greening. The environmentally-friendly water-saving type root infiltrating irrigation device comprises infiltrating irrigation tubes and a water supply system connected with the infiltrating irrigation tubes. U-type leakage-prevention grooves are formed below the infiltrating irrigation tubes, first waterproof layers are arranged at the bottoms of the leakage-prevention grooves, a drainage plate, a second waterproof layer and a root stopping layer are sequentially arranged below the leakage-prevention grooves, the infiltrating irrigation tubes comprise tube bodies, water outlet channels are formed in the length direction of the tube bodies, a swelling groove is formed in the positions, along one side of the corresponding water outlet channel, of each tube body, the openings of the swelling grooves face the exteriors of the tube bodies, the swelling grooves are provided with only the openings facing the exteriors of the tube bodies, sealing edges are formed along the other sides of the water outlet channels and can be attached to the outer walls of the swelling grooves so as to close the water outlet channels, swelling bodies are arranged inside the swelling grooves and can swell after absorbing water so that the outer walls of the swelling grooves and the sealing edges can be attached, and multiple elastic resetting structures are arranged at the openings of the swelling grooves. Water-saving irrigation can be performed according to the humidity of soil, residual irrigation water and rainwater are collected to keep the humidity of the soil, and plant growth is facilitated.

Description

technical field [0001] The invention relates to a seepage irrigation device, in particular to an environmental protection and water-saving root seepage irrigation device for light greening, which is used for self-regulating water-saving irrigation of artificial greening facilities such as roofs and underground garage tops. Background technique [0002] With the development of urbanization, the land available for greening in cities is becoming less and less. As a form of greening that does not occupy the ground, the greening function of various building roofs has attracted more and more attention: it can not only add green to the city, but also reduce the radiant heat from the roof of building materials and reduce the urban heat island effect. If it is well utilized and promoted to form an urban aerial greening system, its effect on improving the urban environment is immeasurable. [0003] However, the temperature and humidity conditions are often poor on the top of the buil...
