Self-contained underground storage and seepage system

Abstract

The invention discloses a self-sufficient underground storage and infiltration system. The system comprises a concave green space lower than the surrounding ground surface, a plurality of drainage pipes are vertically inserted in the left and right sides of the concave green space in a front-back interval mode respectively, a filtering infiltration layer comprises a planting soil layer, an organism layer, a ceramsite layer and a gravel layer which are sequentially arranged from top to bottom, a plurality of water conveying pipelines are laid near plant root systems of the concave green space,a plurality of pipelines at the bottom of the gravel layer are communicated with a regulating storage pool to make filtered rainwater enter the regulating storage pool through the pipelines, the bottom of the regulating storage pool is connected with a plurality of water supply pipes, each water supply pipe extends upwards from the bottom of the regulating storage pool and sequentially penetratesthrough the gravel layer, the ceramsite layer and the organism layer to reach the portion below the plant root systems and is divided into a plurality of branch pipes, each branch pipe is correspondingly communicated with one water conveying pipeline, the pipe wall of each water conveying pipeline is provided with a plurality of holes, and a capillary pipe is installed on each hole. By means of the system, accurate irrigation can be achieved, and the growth of plants is facilitated.

Description

technical field [0001] The invention relates to the fields of pesticide irrigation and urban rainwater runoff control, in particular to a self-supporting underground seepage storage system. Background technique [0002] With the continuous expansion of the city scale, the original green space and farmland are gradually replaced by buildings and other impermeable ground. Human activities have changed the structure and function of the urban surface environment. The hydrological and ecological effects of the river basin affect the hydrological elements such as interception, infiltration and evaporation of rainwater, which intensifies the frequency and intensity of flood disasters in the basin. [0003] In addition, with the continuous improvement of the level of urbanization and the continuous improvement of people's lives, my country's water resources have become particularly scarce. Especially as my country is a large agricultural country, water resources are an important fa...

Problems solved by technology

At present, there have been relevant studies on low-impact development facilities such as the integrated system of infiltration, filtration and collection of runoff developed based on sunken green spaces, but how to recycle the subsequent collected runoff often uses various Power facilities such as water pumps are used to assist subsequent irrigation of the soil, which leads to additional resource consumption
