Description

A kind of Rain Garden
Technical field
The utility model relates to Rain Garden technical field, specially a kind of Rain Garden.
Background technique
With the improvement of living standards, requirement of the people to residential environment is higher and higher, Rain Garden comes into being.Rainwater Garden is the scrobicula greenery patches of self-assembling formation or hand digging, is converged and is absorbed from roof by the comprehensive function of plant, sandy soil Or the rainwater on ground, soil is gradually penetrated into after making rainwater purification, recharging groundwater or supply landscape water, lavatory water etc. are A kind of rainwater utilization facility of ecological sustainability.
Summary of the invention
The purpose of this utility model is to provide a kind of Rain Gardens, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of Rain Garden, it is characterised in that: packet Foundation pit and the concrete cushion for being set to foundation pit lower part are included, is provided with overflow well and drainpipe on the concrete cushion, it is described Gap is installed at the top of overflow well, is successively equipped with metalling, geotextiles and medium soil layer, institute from the bottom to top in the foundation pit State the blind pipe that tube wall aperture is equipped in metalling.
Sponge urban construction is primarily exactly that nature accumulates, and by " cavernous body ", (cavernous body includes that city is green for accumulation naturally Plant, river, lake, park, porous pavement, wetland, beach etc.) under seep, it is stagnant store, purification, reuse, accumulated by pipe network, thus The standard that sewerage system can be effectively improved extenuates the pressure of urban waterlogging.It secondly is exactly naturally osmotic, by taking green Roof, concave herbaceous field, Rain Garden, permeable pavement, the technological means such as grass planting ditch allow rainwater naturally osmotic to underground, a side Urban waterlogging is alleviated in face, on the one hand balances underground water.Sponge urban construction has gone out outside the cavernous body for protecting city, most important Infiltration link is exactly carried out, and the permeable pavement for permeating link is then very easy to accomplish and can be widely applied.Permeable paving The preferred beautiful solid colorful water-permeable entirety road surface of dress, it is environmentally protective, it is durable.
Compared with prior art, the utility model has the beneficial effects that the Rain Garden can be effectively removed in runoff Suspended particulate, organic pollutant and heavy metal ion, the harmful substances such as pathogen, pass through reasonable plants configuration, rainwater Garden can provide good habitat for insect and birds, pass through the adjustable environmental air of the transpiration of its plant Humidity and temperature, improve microclimate environment.The constructions cost of the utility model Rain Garden is lower, and maintenance and management is than grass Level ground is simple, and Rain Garden can give new landscape perception and visual experience.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
FIG. 1 is a schematic structural view of the utility model.
In figure: two cloth of 1-, one film, 2- metalling, 3- blind pipe, 4- overflow well, 5- concrete cushion, 6- drainpipe, 7- spilling water Mouthful, 8- gravel, 9- medium soil layer, 10- geotextiles.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the present embodiment Rain Garden, including foundation pit and the concrete cushion 5 for being set to foundation pit lower part, coagulation Overflow well 4 and drainpipe 6 are provided on soil padding 5, the top of overflow well 4 installs gap 7, is equipped with position around overflow well 4 In the gravel 8 on medium soil layer 9.Drainpipe 6 is connected to municipal catch-basin.Successively be equipped with from the bottom to top in foundation pit metalling 2, There are ballast grain sizes successively to reduce three layers from the bottom to top for geotextiles 10 and medium soil layer 9, metalling 2.It is equipped in metalling 2 blind Pipe 3.The main function of blind pipe is to be discharged into overflow well after rainwater is collected after the filtering of cavernous body filtering layer by blind pipe, then pass through and overflow Stream well discharges into Storm Sewer Network.
As shown, the foundation pit inner wall of 2 top of metalling is equipped with two cloth, one film 1, two cloth, one film is composite geo-membrane It is a kind of.
The present embodiment Rain Garden construction method is as follows:
1. prospecting scene first, determines construction location, construction area rubbish is cleared up, and have bad luck, prepared for later period unwrapping wire.
2. after clear table, unwrapping wire, especially arc position strictly are got ready by drawing cavernous body position coordinates be subject to and put a little more Then, guarantee the round and smooth beauty of circular arc.
3. earth excavation calculates elevation, digs out the extra earthwork and have bad luck using gray line as boundary, manual cleaning corner location, Plain soil layer compacting.
4. building overflow well and inspection shaft, it is laid with storm sewer (by the unified way of municipal administration) and is connected to catch-basin.
5. being laid with rubble, totally 3 layers of rubble, ballast grain sizes successively become smaller from first layer to third layer in Rain Garden, therefore every It is artificial smooth after layer rubble is completed, next layer is re-layed, to guarantee that the thickness of every layer of rubble reaches requirement, bidding in cavernous body High point determines the thickness of metalling referring to relief.
6. being laid with blind pipe, subject to 100 squares of layings, 50 meters of blind pipes, ensure that blind pipe is embedded among rubble when being laid with blind pipe.
7. geotextiles and two cloth, one film (not needing then to be laid with two cloth, one film other than 3 meters from building) are laid with, according to sponge The shape of body spreads geotextiles, and joint guarantees there are 20 centimeters.
8. last laying medium soil, first determines minimum point and highest point, make it is moulded, it is artificial thin after first digging machine It is whole.
9. elevation control installs overflow well lid and manhole cover.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
