Ecological lawn with siphoning water drainage, collection and reutilization system

Abstract

The invention discloses an ecological lawn with a siphoning water drainage, collection and reutilization system. The ecological lawn comprises a waterproof reinforced concrete top plate, wherein a waterproof layer, a heat insulation layer, a fine aggregate concrete protection layer, a water discharging and storage layer and a planting soil layer are arranged laid on the waterproof reinforced concrete top plate in sequence. The ecological lawn further comprises the siphoning water drainage and collection system. The siphoning water drainage and collection system comprises a plurality of siphoning water drainage tanks, a water drainage pipe and a storage pond, wherein a plurality of observing pipes and a plurality of observing wells are arranged on the water drainage pipe, the observing pipes and the observing wells are distributed in an equal-distance, alternative and spaced mode, the siphoning water drainage tanks are located in the water discharging and storage layer, and the siphoning water drainage tanks are distributed among adjacent irregular water discharging and storage pieces of the water discharging and storage layer. The ecological lawn is reasonable in structural design, the water level of the planting soil layer can be kept lower, air and water permeability of soil are kept, normal growth of plant root systems is ensured, water in the water discharging and storage layer can be also discharged to the observing wells through the siphoning water drainage tanks in an organized mode and converges in the storage pond for secondary recycling, and water resources are saved.

Description

technical field [0001] The invention belongs to the technical field of green buildings, in particular to an ecological lawn with a siphon drainage collection and reuse system. Background technique [0002] With the continuous deepening of the urbanization process, the construction land in the city is becoming increasingly tense, the green area is gradually shrinking, and the quality of the living environment is deteriorating day by day. Therefore, people pay more and more attention to planting plants such as grass, small trees or flowers on the surface of underground garages, roofs and other structures. , Degrading floating dust in the air, integrating the urban environment, and creating a harmonious society also have good effects. It can also increase the urban green area and beautify the living environment. [0003] However, the planting layer on the surface of underground garages, roofs and other structures will form stagnant water due to long-term rainfall. When the acc...

Problems solved by technology

[0003] However, the planting layer on the surface of underground garages, roofs and other structures will form stagnant water due to long-term rainfall. When the accumulated water rises to a certain height, it is easy to submerge the plant root system and cause the root system to rot.

In response to such situations, some operators have added drainage layers, waterproof layers and blind ditch matching structures on the planting layer to promote the discharge of accumulated water. However, blind ditch drainage has limitations, and local drainage is smooth, but it cannot guarantee smooth drainage in most areas, which is easy to drain. Cause water accumulation, the waterproof layer is in the environment of water accumulation for a long time, it is easy to cause partial leakage of the waterproof layer, and the later maintenance is cumbersome, which not only wastes a lot of manpower, material resources, and financial resources, but also greatly reduces the service life of the entire building
