A kind of rainwater storage seepage tank

Abstract

The invention discloses a novel rainwater storage leakage and tank which comprises a tank body, wherein the tank body is of a dual-layer wall structure; a water storage cavity is formed by a chamber enclosed by an inner wall, a leakage cavity is formed by a chamber between the inner wall and the outer wall; the lower part of the outer wall is provided with a leakage hole; the upper part of the inner wall is provided with overflow holes communicated with the water storage cavity and the leakage cavity; support ribs are arranged in the leakage cavity at intervals. The novel rainwater storage and leakage tank has the beneficial effects that a storage function and a leakage function are integrated, the leakage efficiency is high, the load-carrying performance of the tank body is high, and an extra floor space is not needed to be occupied.

Description

technical field [0001] The invention relates to a rainwater storage device, in particular to a rainwater storage and seepage device arranged underground. Background technique [0002] In the past, the idea of ​​urban construction to solve the problem of rainwater drainage was to quickly discharge block, collect it through the ground stormwater outlet, drain it into the municipal rainwater pipe network system, and finally divert it to natural waters. This treatment method does not consider the collection and reuse of rainwater, which wastes natural resources, and does not set up storage and purification facilities. In the heavy rainfall environment, the garbage and sundries involved in the pipeline system by rainwater not only easily block the pipeline, It will also cause environmental pollution to natural waters. [0003] In order to solve the above problems, the country has proposed the concept of "sponge city", which is a new concept of stormwater management designed for ...

AI Technical Summary

Problems solved by technology

[0004] The idea of ​​storing and utilizing rainwater in the prior art is to store it in large-scale storage tanks, and then transport it through pipelines or transfer tools when needed. Such large-scale storage tanks have high maintenance costs, and rainwater volatilization and transportation The degree of waste such as consumption is relatively serious, and the real energy saving and environmental protection and the full utilization of resources have not been achieved
