Problems solved by technology

These technologies have improved the water permeability of the ground to a certain extent, but because grass-planting bricks and permeable bricks are often rammed plain soil foundations with poor water permeability, or even concrete foundations with poor water permeability, their ability to absorb rainwater is limited. In addition, the rainwater absorbed by the permeable bricks is difficult to penetrate into the ground, and the effective use of rainwater cannot be realized

Embodiment 1

[0042] A kind of rainwater recycling system in residential quarters, see figure 1 shown, including:

[0043] Permeable ground 1: such as figure 2 As shown, it includes a permeable brick layer 11, a filter layer 12, a first crushed stone layer 13, a coarse sand layer 14, an activated carbon layer 15 and a second crushed stone layer 16 arranged sequentially from top to bottom, and the bottom of the second crushed stone layer 16 A drain pipe 17 and a water diversion plate 18 are provided, the drain pipe 17 is arranged in the middle of the second gravel layer 16, and extends along the front and rear directions, the water diversion plate 18 is arranged in a V shape, and the drain pipe 17 is located in the middle of the water diversion plate 18;

[0044] Water collection tank 2: used to collect the rainwater infiltrated by the permeable ground 1, and its water inlet is connected to the drain pipe 17;

[0045] Water treatment tank 4: located underground, its top is provided with a...

Embodiment 2

[0048] On the basis of embodiment 1, this embodiment is further set to:

[0049] Such as image 3 As shown, the permeable brick layer 11 is composed of several permeable brick groups arranged in parallel, and each permeable brick group is formed by inserting several permeable bricks in sequence; the filter layer 12 is formed by laying several filter boxes, and the permeable bricks directly Laying on the filter box, the upper surface of the filter box is a perforated support frame 122 for supporting permeable bricks, the lower surface of the filter box is a permeable bottom that can permeate water, and a detachable filter screen 121 is arranged in the filter box. The upper surface of the permeable brick is evenly distributed with a number of anti-slip protrusions 111, and there are a number of drain holes 112 arranged in parallel in the permeable brick, and the drain holes 112 extend vertically and run through the entire permeable brick. Further preferably, the diameter of the...

Embodiment 3

[0051] On the basis of embodiment 2, this embodiment is further set to:

[0052] Such as Figure 4 As shown, the left side of the permeable brick is provided with an embedded groove 113, and the right side of the permeable brick is provided with an embedded protrusion 114 that matches the embedded groove 113, and the adjacent permeable bricks pass through the embedded groove 113 and the embedded protrusion. 114 realizes plugging. The permeable bricks are connected together by plugging in sequence from the end to the end. Only the leftmost and rightmost permeable bricks need to be fixed to realize the fixing of the entire permeable brick group. The bottom of each permeable brick does not need to be bonded to the cement layer with poor water permeability. .

Abstract

The invention relates to a rainwater recovery system for a residential district. The rainwater recovery system comprises a water-permeable ground, a water collecting tank and a water treatment tank, wherein the water-permeable ground comprises a water-permeable brick layer, a filter layer, a first crushed stone layer, a coarse sand layer, an activated carbon layer and a second crushed stone layerwhich are sequentially arranged from top to bottom; a drainage pipe and a water guiding plate are arranged at the bottom of the second crushed stone layer; the drainage pipe is arranged at the middleof the second crushed stone layer and extends in the front-rear direction; the water guiding plate is V-shaped; the drainage pipe is positioned at the middle of the water guiding plate; the water collecting tank is used for collecting rainwater penetrating through the water-permeable ground; a water inlet of the water collecting tank is connected to the drainage pipe; the top of the water treatment tank is provided with a water treatment partition plate hanging over the bottom of the water treatment tank; the water treatment partition plate divides the water treatment tank into a water treatment part and a water outlet part; the bottom of the water treatment part communicates with the bottom of the water outlet part; the top of the water treatment part is connected to a water outlet of thewater collecting tank; and the top of the water outlet part communicates with an external landscape pond. Compared with the prior art, the rainwater recovery system for the residential district not only clears the road after the rainwater penetrates into the ground so as to significantly improve the absorptive capability to the rainwater, but also improves the resource utilization rate of the rainwater.

Description

technical field [0001] The invention relates to the field of landscape design, in particular to a rainwater recovery system for residential quarters. Background technique [0002] At present, the water permeability of most garden roads is poor, and the ability to absorb and discharge rainwater is very limited. When the rainfall exceeds the absorption capacity of the ground, if there is a lack of underground drainage facilities, the excessive rainwater will not be discharged in time, which will directly cause the garden road to be flooded by rainwater, seriously hindering people's walking. At the same time, the existing garden roads are relatively simple, and the rainwater cannot be fully utilized. Therefore, when there is sudden heavy rain or continuous rainfall, most of the garden roads are often paralyzed due to accumulated water, which brings a lot of inconvenience to people. . [0003] In order to solve the above problems, people put forward the concept of sponge city,...
