Temperature-adaptive water storage and drainage integrated water permeable brick

Abstract

The invention provides a temperature-adaptive water storage and drainage integrated water permeable brick. The brick comprises a modified sand base layer, a water storage cavity, two permanent magnetsarranged in a homopolar manner and a waterproof base layer which are sequentially arranged from top to bottom, a drainage pipe is arranged at the bottom of the waterproof base layer, and the water storage cavity is composed of a water sealing plate and bearing solid pipes located at the two sides of the upper portion of the water sealing plate. An expansion air bag containing low-boiling-point evaporation liquid is arranged at the outer side of each bearing solid pipe, and a heat insulation sliding plate is arranged at the side portion of each expansion air bag, and the expansion air bags arevaporized and expanded to push the corresponding heat insulation sliding plates to move in the direction away from the expansion air bags. The temperature-adaptive water storage and drainage integrated water permeable brick is reasonable in design and ingenious in structure, when the rainwater amount is smaller or the surrounding environment temperature is higher, the surrounding environment temperature can be continuously kept cool due to the evaporation effect of water stored in the water storage cavity or water overflowing due to the effect of the expansion air bags, rainwater is fully utilized, meanwhile, the water storage amount in the water storage cavity can be automatically adjusted, the livable index of a city is improved, and meanwhile, the heat island effect of the city is relieved.

Description

Technical field[0001]The invention relates to a temperature-adaptive integrated water storage and drainage permeable brick.Background technique[0002]The sponge city includes six steps: infiltration, stagnation, storage, purification, utilization, and drainage. The permeable bricks of the sponge city reduce the accumulation of water on the road surface, facilitate citizens to travel, beautify the environment, prevent waterlogging and alleviate the urban heat island effect to a certain extent. However, traditional permeable bricks have simple structure and are easy to block, have single functions, only have the functions of beautification and permeation, and cannot integrate the functions of seepage, storage, use, and drainage. The economic benefits and actual effects are poor. In addition, public places such as urban parks with a large flow of people and surrounding urban areas have a significant heat island effect. Traditional permeable bricks cannot make full use of the rainwater d...

Problems solved by technology

However, the traditional permeable bricks have a simple structure and are easy to block, and have a single function. They only have the functions of beautification and water permeability, and cannot integrate the functions of seepage, storage, use, and drainage. The economic benefits and actual effects are poor.

In addition, urban parks and other public places with a large flow of people and the surrounding urban areas have a significant heat island effect. Traditional permeable bricks cannot make full use of the rainwater during the rainfall period to effectively cool the surrounding environment, which is a great threat to natural resources. waste

[0003] Aiming at the problems of poor functionality and easy clogging of traditional permeable bricks, the present invention provides a temperature-adaptive integrated water storage and drainage permeable brick
