Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, a formula of sinking greenery patches, this formula of sinking greenery patches includes body 1 and spillway well 2, and the main part can include planting layer 11, geotechnological cloth layer 12 and gravel layer 13 that permeates water, plants layer 11, geotechnological cloth layer 12 and gravel layer 13 and lay from top to bottom in proper order, wherein, has laid planting soil in planting layer 11, and planting soil can be formed by sand, compost and loam soil mixture, and the infiltration parameter of planting soil is great like this, and planting layer 11 is used for planting the plant, and the preferred, the plant is drought-enduring waterlogging variety. The upper surface of the planting layer 11 is the upper surface of the body 1. The permeable geotextile layer 12 comprises a permeable geotextile. The permeable geotextile can separate the planting layer 11 from the gravel layer 13. The gravel layer 13 is provided with gravels, and the gravel layer 13 can effectively store rainwater due to a large gap between the gravels. The overflow well 2 is arranged in the main body, the overflow well 2 sequentially penetrates through the planting layer 11, the permeable geotextile layer 12 and the gravel layer 13, and one end of the overflow well 2 with an overflow well mouth 23 extends out of the surface of the main body 1, namely out of the upper surface of the planting layer 11. Detachably is provided with overflow well lid 3 on overflow well 2, and overflow well lid 3 can open and shut for overflow well 2, and overflow well lid 3's shape is the round platform shape, and the size of the terminal surface of keeping away from overflow well mouth 23 of overflow well lid 3 is less than the size of another terminal surface of overflow well lid 3. Thus, rainwater can flow down along the side wall of the overflow well cover 3. In addition, if the rainwater is too large, the rainwater may be retained on the upper surface of the body 1, in order to accelerate the speed of rainwater entering the overflow well, a plurality of rainwater openings 31 can be formed in the side wall of the overflow well cover 3, each rainwater opening 31 is a strip-shaped rainwater opening 31, a gap is formed between every two adjacent rainwater openings 31, and the rainwater retained in the rainwater can enter the overflow well 2 through the rainwater openings 31 of the overflow well 2. In addition, in order to prevent the rainwater from entering the rainwater inlet 31 along with the larger garbage to cause the rainwater inlet 31 to be blocked, each rainwater inlet 31 can be provided with a filter screen 32, and the filter screens 32 can be connected with the corresponding rainwater inlets 31 through screws. Overflow mouth 21 can have been seted up to the one end that the well head was kept away from to the overflow well, and overflow mouth 21 is circular mouth, and overflow mouth 21 is used for being connected with municipal pipe network, makes the rainwater in the overflow well 2 get into municipal pipe network.
In above-mentioned technical scheme, overflow well 2 is installed to body 1, and when heavy rain falls down, the rainwater that is detained on planting layer 11 can get into overflow well 2 from inlet for stom water 31, and the quick bottom that flows to overflow well 2 from overflow well 2 to get into municipal pipe network from overflow mouth 21.
In order to facilitate rainwater to enter the municipal pipe network from the overflow port 21, a rainwater connecting pipe 4 can be further arranged, and the overflow port 21 is connected with the municipal pipe network through the rainwater connecting pipe 4. Preferably, rainwater connecting pipe 4 can be the hose that permeates water, because the lateral wall of the hose that permeates water can permeate the hydrone, so the rainwater that is detained at rainwater connecting pipe 4 outer wall also can get into the hose that permeates water through the infiltration, then gets into municipal pipe network together along with overflow mouth 21 exhaust water.
Here, it should be noted that: the pipe body of the rainwater connection pipe 4 may be disposed in the gravel layer 13. If the pipe body of the rainwater connection pipe 4 is installed in the planting layer 11, plants may have an influence on the rainwater connection pipe 4. Preferably, the rainwater connection pipe 4 is disposed at an upper portion of the gravel layer 13. Because the rainwater connecting pipe 4 is buried in the upper portion of the gravel layer 13, the function of storing water in the gravel layer 13 at the lower end can be performed, and if the rainwater connecting pipe 4 is buried in the bottom portion of the gravel layer 13, a large amount of moisture in the gravel layer 13 above the rainwater connecting pipe 4 can enter the rainwater connecting pipe 4 at the lower end, resulting in an insufficient water storing effect of the gravel layer 13.
In addition, as shown in fig. 1, the sunken green land may further include cobblestones 5. An annular flange 22 is integrally assembled at the overflow well mouth 23, the annular flange 22 is abutted with the upper layer of the planting layer 11, and the cobblestones 5 can be laid on the annular flange 22. Like this cobblestone 5 can prevent that the upper end of overflow well from removing and leading to the overflow well to damage, cobblestone 5 can play the warning effect moreover, prevents that the pedestrian from colliding with 23 departments at the overflow well mouth.
The implementation principle of the embodiment is as follows:
when raining, rainwater falls on the plants of the planting layer 11, then permeates into the permeable geotextile layer 12 below along the planting layer 11, and as the permeable geotextile layer 12 can permeate water but cannot permeate objects, the water continuously permeates into the gravel layer 13 below, and the planting soil is kept in the planting layer 11. While the moisture penetrated into the gravel layer 13 may remain in the gravel layer 13. When heavy rain falls, rainwater may be retained on the upper surface of the planting layer 11, and the retained rainwater can enter the overflow well 2 through the rainwater inlet 31 of the overflow well 2, so that the rainwater can flow at a high speed. And the bottom of overflow well 2 is connected with rainwater connecting pipe 4, and rainwater connecting pipe 4 is connected with municipal pipe network, and the rainwater can follow rainwater connecting pipe 4 and channel into municipal pipe network. In this process, because rainwater connecting pipe 4 is the hose that permeates water, the water that gets into rainwater connecting pipe 4 like this can get into gravel layer 13 below through the lateral wall of the hose that permeates water, can accelerate the speed that gravel layer 13 stored water.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
