Description

A kind of structure of the Rain Garden that trapezoidal gabion is enclosed
Technical field
This utility model is related to a kind of structure of Rain Garden, the Rain Garden that more particularly to a kind of trapezoidal gabion is enclosed Structure.
Background technology
Rain Garden is the scrobicula greenery patches of self-assembling formation or hand digging, is used for converging and absorbing from roof or ground The rainwater in face, is purified rainwater by the comprehensive function of plant, sandy soil, and is allowed to gradually penetrate into soil, recharging groundwater, Or be allowed to feed the urban waters such as landscape water, lavatory water.It is a kind of ecological sustainability based on low impact utility strategies Rainwater management and rainwater utilization facility.
Rain Garden has three features.First, the area of Rain Garden is larger, therefore, urban storm intensity larger, drop In the case that the water yield is more can rapid, substantial amounts of collection rainwater, in place and its periphery rain disaster have larger Alleviate.Second, such Rain Garden can effectively supplement urban groundwater, the bio-diversity in protection city, realize city The sustainable use of water resource.3rd, in terms of landscape molding, such Rain Garden can create the rainy season scape different from dry season Effect is seen, the resident for periphery provides leisure, the good place to go that takes a walk.
Conventional Rain Garden is gone along with sb. to guard him due to lacking clear and definite border, and the border gradient of Rain Garden is generally required less than 30 degree Within, not so its border soil under the washing away of rainfall runoff will be lost in Rain Garden bottom, limit Rain Garden to rain The implicit ability of water, also causes harmful effect to the Stability Analysis of Structures and vegetation growth state of Rain Garden.On the other hand, enter The water quality of Rain Garden cannot be guaranteed, the plant growing situation in Rain Garden is also increased without preliminary filtration, water quality Uncertain factor is added.
Therefore, for deficiency described above, needing one kind effectively consolidate Rain Garden border prevents rain drop erosion Soil erosion is caused, while have the Rain Garden with firm border of good filtration to early-stage rainwater again.
Utility model content
The purpose of this utility model is structure and its structure for designing the Rain Garden that a kind of new trapezoidal gabion is enclosed Construction method, solves the above problems.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of structure of the Rain Garden that trapezoidal gabion is enclosed, including original soil layer, blotter, geotextiles, plantation soil layer With trapezoidal gabion;The trapezoidal gabion encloses the default place of rotund Rain Garden, and the circle is distinguished from bottom to top For original soil layer, blotter, geotextiles and plantation soil layer;The trapezoidal gabion is installed on the week in the default place of the Rain Garden Side, the trapezoidal gabion are enclosed using expanded sheet metal, and the section of the trapezoidal gabion is trapezoidal, inserts in the trapezoidal gabion Cobble.
Further, the trapezoidal gabion is boulder bed, Flyash Layer and vermiculite layers from outside to inside successively, the trapezoidal stone Cage is layered with expanded sheet metal, then is coupled together each layer with ring fastener;The boulder bed inserts not advising for diameter 50mm-80mm The then cobble of shape;The Flyash Layer inserts the flyash wrapped up with geotextiles, and the particle size range of fly ash grain is 0.5 μ m-300μm;The vermiculite layers insert Vermiculitum, and the vermiculite layers are located at soil of the trapezoidal gabion innermost layer near Rain Garden Earth.
Further, boulder bed, Flyash Layer, the width ratio of vermiculite layers are 3:2:3.
Further, the hypotenuse of the trapezoidal gabion is with the horizontal 20 ° -60 ° of angle.
Further, the original soil layer is the default original soil layer in place of the Rain Garden;The blotter is inserted broken Stone, the thickness of the blotter is 150mm-250mm;The geotextiles are covered in above the metalling;The planting soil Layer inserts the soil of planting plants, and the plantation soil thickness is 400mm-600mm, and the plantation soil layer is covered in the geotechnique Above cloth.
Further, also include that wood flour layer, the wood flour layer are covered in above the plantation soil layer, the wood flour thickness degree For 30mm-50mm.
A kind of construction method of the Rain Garden that trapezoidal gabion is enclosed, comprises the steps:
(1) according to the default size of Rain Garden, Slag bottom is excavated as original soil layer, lay metalling on original soil layer To consolidate substrate;
(2), after compacting substrate, geotextiles are laid;
(3) trapezoidal gabion is enclosed with steel wire iron plate, and be installed on default four side of place of Rain Garden, the trapezoidal gabion Section is trapezoidal, after inserting cobble, is sealed with connector in the trapezoidal gabion;
(4) planting soil is backfilled in the geotextiles, planting soil is not compacted, sow grass seeds or plant scape in planting soil See grass.
Further, in step (2), the hypotenuse of the trapezoidal gabion is with the horizontal 20 ° -60 ° of angle.
Further, the thickness of metalling described in step (1) is 150mm-250mm;Described in step (4) Plantation soil thickness is 400mm-600mm, and the permeability of the planting soil is 100mm/hr-600mm/hr.
Further, also comprise the steps:(5) the thick wood flours of uniform fold 30mm-50mm on planting soil.
The beneficial effects of the utility model can be summarized as follows:
1. the Section Design of gabion is trapezoidal.The border of Rain Garden is so not only made to seem gentle, it is ensured that visual Landscape Effect, that 20 ° -60 ° of the gradient can be gentler is joined with garden bottom mima type microrelief.
2. the Rain Garden that gabion is enclosed is prevented from rain drop erosion and causes soil erosion, lays ovum in water inlet bottom Stone, weakens impulsive force.
3. select gabion as the main material on Rain Garden border, there are three reasons:
(1) economy, environmental protection.By the use of multiple materials with pollutant Filtration Adsorption ability as internal packing material;
(2) permeability, filterability.Gap in gabion is conducive to rainwater to enter Rain Garden, while again to early-stage rainwater There is good filtration;
(3) accumulate in gabion after a certain amount of soil impurity can natural growing plant, ecological effect and landscape effect all good.
4. gabion by the boulder bed of vertical direction, Flyash Layer, vermiculite layers according to 3:2:3 composition of proportions, wherein cobble Layer can play screening effect, filter the bulky grain pollutant in runoff;Fly ash grain compares table in porous type cellular tissue Area is larger, with higher adsorption activity.And Zhu Bi has a loose structure, porosity up to 50% 80% has very strong Water absorption;Therefore, it is possible to filter and adsorb small particles of pollution thing, and the effect with delay, water-retention.
