Abstract
The utility model discloses an ecological embankment. The ecological embankment comprises a foundation, an embankment and a protective slope, wherein the foundation and the embankment are made of rock-fill concrete, the protective slope is soil body, and two slopes of the embankment are in the shape of stages. The rock-fill concrete used in the ecological embankment takes the large-particle-size rock-fill as aggregates, thereby reducing cement usages, saving costs, speeding up construction speed, and effectively reducing the hydration heat of concrete. Therefore, the ecological embankment has the advantages of simple manufacturing processes, less construction links, small floor spaces, and enabling to be used under multi-foundation conditions. Because the protective slope is soil body, plants such as grass and low shrubs can be planted on the soil body and the plants are adaptable to the soil body, thereby strengthening the effect of beautification.
Description
Technical field
The present invention relates to a kind of ecological dyke, this ecology dyke can be brought into play flooding action and Greening functions simultaneously.
Background technology
The urban flood defence dike is coastal or the requisite water conservancy projects in city, river, and the dike type can have multiple choices according to the difference of dyke standard.The earth embankment levee body uses core-wall or sloping core antiseepage, and arranges drainage etc.But surface self-sow or sowing plant, natural landscape is better.But the earth embankment floor space is large, and foundation dredging and processing engineering quantity are large, are unfavorable for adopting in urban flood defence.Gravity dam formula dyke uses the rigid materials such as concrete, stone-laying to fill, have the space of saving, safety factor advantages of higher, but because gravity dam formula dyke surface be towering light face often, stopped that people contact with natural soil, water etc., ecological, attractive in appearancely all suffered damage.
The river channel ecology bank protection comprises plant type bank protection, timber bank protection and stone material bank protection etc., and bank protection commonly used is grassed slope, riprap and wire basket bank protection etc.Above-mentioned river course slope protection purpose mostly is the reinforcing river levee, satisfies simultaneously the requirements such as ecological, attractive in appearance.But without the antiseepage function, stability is lower, and flooding action is faint.
Summary of the invention
The purpose of this invention is to provide a kind of ecological dyke, is that a kind of ecological dyke based on rock-fill concrete is the combination of rock-fill concrete dyke main body and ecological revetment.
A kind of ecological dyke provided by the present invention, it comprises basis, levee body and protective slope; Described basis and levee body are built by rock-fill concrete and are obtained.
The used rock-fill concrete of the present invention is that the boulder/cobble that will satisfy certain particle diameter requirement (generally greater than 30cm) directly puts in storage, and is formed with the rockfill in space; Then satisfy the self-compacting concrete (Self-Compacting Concrete is called for short SCC) of particular requirement at the rockfill surface casting, fill and form closely knit concrete; Adopt described rock-fill concrete as levee body, can have dash and antiseepage effect concurrently, can save the seepage control method of levee body.
In the above-mentioned ecological dyke, described protective slope specifically can be the soil body, and its top layer can adopt endemic plant or turf to cover, and landscaping effect is good and simple and easy to do.
In the above-mentioned ecological dyke, two of described levee body are domatic all to be can be step-likely, and this setting can be satisfied the stability of outside institute earthing body (being protective slope).
In the above-mentioned ecological dyke, the slope ratio of the back side of described levee body can be 1:(0.2 ~ 2), the slope ratio of the face near water of described levee body can be 1:(0 ~ 1), but be not 1:0, to satisfy stable and stress requirement.
In the above-mentioned ecological dyke, the slope ratio of described protective slope can be less than 1:0.3, and described slope is than hour, and the domatic of described protective slope can be domatic close to level.
The present invention has following beneficial effect: rock-fill concrete of the present invention with large particle diameter enrockment as aggregate, reduce cement consumption, save cost, speed of application is fast, can effectively reduce the concrete heat of hydration, the technique when therefore making ecological dyke of the present invention is simple, and construction link is few, and ecological dyke floor space less provided by the invention can adopt under multiple foundation condition.Protective slope adopts the soil body, on the soil body planting plants such as grass, low brushwood etc., strong adaptability, landscaping effect is good.
Description of drawings
Fig. 1 is the structural representation of ecological dyke provided by the invention.
Each mark is as follows among the figure: 1 basis, 2 levee bodys, 3 protective slopes, 4 plants.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing, but the present invention is not limited to following examples.
The ecological dyke that the present embodiment provides as shown in Figure 1, it comprises basis 1, levee body 2 and protective slope 3; Wherein basis 1 and levee body 2 are built by rock-fill concrete and are obtained, and all can build by construction method for rock-fill concrete dam, two of this levee body 2 are domatic be designed to step-like so that the building of follow-up protective slope; This protective slope 3 is the soil body, can be used for planting plants 4 on it, is used for beautifying the environment; The back side slope of this levee body 2 is than being 1:0.2, and the face slope is than being 1:0.2, to satisfy stable and stress requirement near water; The slope of this protective slope 3 is than being 1:0.5.
In the above-mentioned ecological dyke, the comprehensive slope of the back side of levee body 2 than and near water the comprehensive slope of face than can be respectively in 1:(0.2 ~ 2) and 1:(0 ~ 1) scope in adjust, and the slope of face is 1:0 than not near water; The slope of protective slope 3 is than less than 1:0.3, and when it got minimum value, this is domatic, and to form a level domatic.
When making above-mentioned ecological dyke, according to " Code for design of levee projects " related request, the rock-fill concrete dyke of calculation Design height is under the different levee body gradients, levee foundation stress level, Against Sliding Stability and overturning or slip resistance analysis are stable, make upstream face and back side levee body without tensile stress, the levee body maximum crushing stress is lower than compressive strength, and Against Sliding Stability coefficient and the overturning or slip resistance analysis coefficient of stability are greater than the regulation and stipulation permissible value.
The gradient of protective slope can be determined according to " Technique Code for Building Slope Engineering " computational analysis.
In the above-mentioned computational process, non-flood season, upper earthing body applies gravity pressure to basis and levee body, elevation is identical with levee crown if banket behind the dike, then should calculate simultaneously its to the level of levee body to soil pressure, should calculate levee foundation minimax stress and ratio thereof, Against Sliding Stability, the overturning or slip resistance analysis coefficient of stability this moment, and compare with standard; Flood period, the soil body can calculate gravity pressure by buoyant unit weight before the dike, and levee foundation is subjected to the uplift pressure effect, should check seepage flow under foundation stability and minimax stress and ratio, Against Sliding Stability, the overturning or slip resistance analysis coefficient of stability this moment, needs in case of necessity ground is carried out respective handling.
