Abstract

The utility model discloses a drainage structures suitable for meadow, including escape canal, first geotechnological cloth layer, dead leaf bark layer and planting soil layer, from top to bottom lay in the escape canal in proper order on first geotechnological cloth layer, dead leaf bark layer and planting soil layer, the escape canal feeds through to have and is used for going the drinking device who guides outside the escape canal with water. The utility model discloses a form inseparable scour prevention structure with the combination on first geotechnological cloth layer and dead leaf bark layer, simultaneously, water at the bottom of the timely discharge gutter of drinking device avoids ponding to make the escape canal loosely organized, improves the structural stability in escape canal, and then prolongs this drainage structures suitable for meadow's life, simultaneously, there is stronger retentivity on dead leaf bark layer to organic pollutant, and plant roots has purification performance, has improved this drainage structures suitable for meadow's blowdown ability, furtherly, it grows in the grass seeds on planting soil layer to sneak into forms the grass web frame, improves the stability erosion resistibility in escape canal jointly.

Description

A kind of discharge structure being applicable to meadow

Technical field

This utility model relates to discharge structure, particularly for the discharge structure of planting site.

Background technology

Draining grass ditch receives much concern as a kind of emerging Demonstration for Ecological Sanitation facility, and draining grass ditch refers to Plant the earth's surface irrigation canals and ditches having vegetation, can collect, carry and discharge runoff rainwater, and have certain Rainwater purification effect, can be used for being connected other each individual event facilities, urban rainwater canal system system and surpassing Mark rainfall runoff exhaust system.Traditional draining grass trench system be from top to bottom equipped with divot and Plantation soil layer, complete owing to turf fails to grow covering in time at first stage of construction, or by construction matter Amount impact, causes planting soil easily to be taken away by rain drop erosion and produces alluvial in downstream, have impact on Cutting of grass ditch is dirty, retain and landscape effect.

Utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide one to be suitable for In the discharge structure on meadow, its erosion resistibility, pollution discharge capability and stability can be improved.

The purpose of this utility model realizes by the following technical solutions:

A kind of discharge structure being applicable to meadow, including gutter, the first geotechnique layer of cloth, dead leaf Tree skin layer and plantation soil layer；First geotechnique's layer of cloth, dead leaf tree skin layer and plantation soil layer are from top to bottom It is layed in successively in gutter；The bottom in described gutter be communicated with for by water toward outside gutter The priming device guided.

Preferably, the plantation of described plantation soil layer has grass seeds.

Preferably, the bottom of trench in described gutter is lower arcuate surface.

Preferably, described priming device include respectively with the multiple main draining connected bottom gutter Pipe, each main drainpipe is all communicated with arm；Described drawing is provided with water seepage hole on main drainpipe.

Preferably, it is equipped with sandy soil layer below plantation soil layer.

Preferably, gravel layer and second geotechnique's layer of cloth it are equipped with below sandy soil layer successively.

Compared to existing technology, the beneficial effects of the utility model are: this utility model passes through will The combination of first geotechnique's layer of cloth and dead leaf tree skin layer forms close Anti-scouring structure, thus can carry The while of its erosion resistibility high, the hydrops at the bottom of the timely discharge gutter of priming device, it is to avoid hydrops makes row Ditch structure is loose, improves the structural stability in gutter, and then prolongation is originally applicable to meadow The service life of discharge structure；Meanwhile, dead leaf tree skin layer has stronger delay to organic pollution Ability, improves the pollution discharge capability of the discharge structure being originally applicable to meadow；And, the first geotechnique The combination of layer of cloth and dead leaf tree skin layer provides applicable raw also can to first kind of grass seeds planted in soil layer Long environment and space, and promote to be mixed into growth formation grass web frame in the grass seeds of plantation soil layer, And root system of plant has purification function, thus can further improve erosion resistibility and the row in gutter Dirty ability.

Accompanying drawing explanation

Fig. 1 is the schematic diagram that this utility model is applicable to the discharge structure on meadow.

Wherein, 1, first geotechnique's layer of cloth；2, dead leaf tree skin layer；3, plantation soil layer；4, husky Matter soil layer；5, gravel layer；6, second geotechnique's layer of cloth.

Detailed description of the invention

Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:

As it is shown in figure 1, a kind of discharge structure being applicable to meadow, including gutter, the first soil Work layer of cloth 1, dead leaf tree skin layer 2 and plantation soil layer 3；First geotechnique layer of cloth 1, dead leaf bark Layer 2 and plantation soil layer 3 are layed in gutter the most successively；The bottom in described gutter Be communicated with for by water toward the priming device guided outside gutter.First geotechnique's layer of cloth 1 and dead leaf Tree skin layer 2 combines and forms close Anti-scouring structure, is possible to prevent gutter to build up initial stage heavy rain The destruction causing gutter structure, improves the erosion resistibility in gutter and stablizing of structure Property, meanwhile, the water of bottom of trench can be discharged to the external world by priming device timely, it is to avoid water overstocks Bottom of trench, makes gutter loosely organized, destroys gutter structural stability, and then it is applicable to extend this Service life in the discharge structure on meadow；Meanwhile, organic pollution is had by dead leaf tree skin layer 2 Stronger retentivity, can improve the pollution discharge capability of the discharge structure being originally applicable to meadow.

Plantation soil layer 3 kinds is implanted with grass seeds, and first geotechnique's layer of cloth 1 and dead leaf tree skin layer 2 are combined into Grass seeds provides environment and the space being suitable for growth, promotes grass seeds to germinate smoothly growth, grass planting root system Form grass web frame the bond strength with raising plantation soil layer 3, and root system of plant constantly absorbs The nutrient substance filtered in planting soil, purifying rainwater, further raising is originally applicable to the row on meadow The erosion resistibility of water-bound, structural stability and pollution discharge capability.

The bottom of trench in gutter is lower arcuate surface, makes water concentrate on bottom of trench, and then facilitates drinking device Water is discharged.

Priming device include respectively with the multiple main drainpipes connected bottom gutter, each main draining Guan Shangjun is communicated with arm, can be collected by water in time and separately be discharged outside to, improve draining effect Being provided with water seepage hole in rate, and main drainpipe, water flows to main drainpipe from water seepage hole, can filter Except the polluter that some are bigger, and this apparatus structure is simple, easy for installation.

It is equipped with sandy soil layer 4 below plantation soil layer 3, can improve under substrate and ooze coefficient, and Filtering the solid sediment in rainwater and heavy metal contaminants, further raising is originally applicable to meadow The pollution discharge capability of discharge structure.

It is equipped with gravel layer 5 and second geotechnique's layer of cloth 6 below sandy soil layer 4 successively, improves this It is applicable to the stability of the discharge structure on meadow.

It will be apparent to those skilled in the art that can technical scheme as described above and structure Think, make other various corresponding changes and deformation, and all these changes and deformation Within all should belonging to this utility model scope of the claims.
