A rainwater penetration detection device suitable for sponge cities

Abstract

The invention provides a rainwater infiltration detection device suitable for sponge cities, the uppermost layer of which is a bioretention zone, a reservoir is arranged on the lower side of the bioretention zone, and a planting soil layer is arranged on the lower side of the reservoir. A coarse sand layer is arranged on the side, and a gravel layer is arranged on the lower side of the coarse sand layer, and a drainage system is arranged in the gravel layer; the drainage system includes a water collection filter plate and a drain pipe; the water collection filter plate includes a first filter plate connected in sequence, The second filter plate and the third filter plate; a plurality of round pipes are arranged in the drain pipe, the ends of the round pipes are connected to a water collection tank, and an electrode liquid level gauge is vertically arranged on one side of the water collection tank. The rainwater infiltration detection device suitable for sponge cities can realize water recycling and regeneration through the above-mentioned structure, can make full use of water resources, and avoid urban waterlogging; at the same time, it can detect the water seepage of the soil structure at any time, and understand the sponge at any time. The infiltration capacity of urban soil structure, in order to make timely emergency measures to deal with.

Description

technical field [0001] The invention relates to a detection device, in particular to a rainwater infiltration detection device suitable for sponge cities. Background technique [0002] At present, "sponge city" is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and coping with natural disasters caused by rainwater. It can also be called "water elastic city". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection; "sponge city" aims to build a good ver...

AI Technical Summary

Problems solved by technology

However, none of the existing sponge city design schemes can realize the real water recycling and regeneration process, resulting in a large amount of water loss or prone to waterlogging

[0004] While setting up the special soil structure of the sponge city, it is necessary to understand the rainwater infiltration capacity of the sponge city soil structure in order to respond to different wind and rain environments in a timely manner. However, the existing detection equipment cannot perform timely water seepage detection on the sponge city soil structure, resulting It is impossible to make the most effective countermeasures according to the water absorption capacity of the soil structure in a timely manner
