Sponge city street tree feeding system

Abstract

The invention relates to a sponge city street tree feeding system, which comprises a road, and a water collecting system for supplying water to grass and trees on two sides of the road, wherein the upper surface of a first impervious layer is a surface layer arranged in an S shape along the length direction of the road; a water outlet trough is arranged under the lowest water outlet surface of thefirst impervious layer along the width direction of the road. According to the sponge city street tree feeding system provided by the invention, when the water in an impounding reservoir is collected, by utilizing the first impervious layer arranged in the S shape, the water stored in the impounding reservoir automatically flows toward the inner part of the water outlet trough along a lower direction and flows into the impounding reservoir along the water outlet trough; the water outlet trough is hollow U-steel so that the water flows smoothly without being blocked; in addition, the bottom part of the impounding reservoir is the S-shaped layer, and the water outlet trough is arranged at the bottommost position of the S-shaped layer, so that the water accumulated in the impounding reservoir can automatically flow toward the inner part of the water outlet trough along the inclined surface of the S-shaped layer surface without being partially remained in the impounding reservoir.

Description

technical field [0001] The invention relates to the technical field of urban water collection, in particular to a system for supporting street trees in a sponge city. Background technique [0002] The surface of modern cities is constantly covered by reinforced concrete buildings and impervious roads. Although the production efficiency and quality of life have been improved, compared with natural soil, ordinary cement concrete floors lack the ability to absorb heat and infiltrate rainwater. A series of problems followed: First, the decrease in the water seepage capacity of the road surface caused serious water accumulation on the road surface in rainy days. Although there are deep wells on the road for drainage, the water accumulation problem still cannot be effectively solved, which will improve the comfort of vehicles and pedestrians. adverse effects on safety and security; [0003] Second, the impermeable road surface is difficult to exchange heat and humidity with the a...

Problems solved by technology

[0002] The surface of modern cities is constantly covered by reinforced concrete buildings and impervious roads. Although the production efficiency and quality of life have been improved, compared with natural soil, ordinary cement concrete floors lack the ability to absorb heat and infiltrate rainwater. A series of problems followed: first, the decrease in the water seepage capacity of the road surface caused serious water accumulation on the road surface in rainy days. Although there are deep wells on the road for drainage, the water accumulation problem still cannot be effectively solved, which will improve the comfort of vehicles and pedestrians. and adverse effects on safety;

[0003] Second, the impermeable pavement is difficult to exchange heat and humidity with the air, and it is easy to produce the "heat island effect", which makes the temperature inside the city too high, leading to climate deterioration

[0004] Third, the imperviousness of the road makes the soil under the road low, which will have a negative impact on the normal growth of the street trees on both sides, and will cause problems such as the tree is not lush enough and the root system pushes the floor tiles on the road out of the ground.
