Abstract
A sand layer cut slope ecological protection structure can effectively resolve the problems of scouring, topsoil slip and stability of sand layer side slopes and facilitate growing of plants on the sand layer side slopes. The sand layer cut slope ecological protection structure comprises a water-blocking framework (20) which is fixedly arranged on an excavated side slope surface (10) and distributed in latticed mode, water-permeable geotextile (11) is laid in griddings of the water-blocking framework (20) along the excavated side slope surface (10), the water-permeable geotextile (11) is laid with hollow building blocks (21), and the hollow building blocks (21) are backfilled with planting soil (22) for planting plants.
Description
Technical field
The utility model relates to the ecological reinforcement protection engineering of side slopes such as railway, highway, water conservancy, particularly a kind of layer of sand cut slope ecological protection structure.
Background technology
Sand-layer foundation mainly is distributed in China's Coastal Areas, and sand-layer foundation is because good water permeability, and excavation layer of sand cut slope receives that flow action is subject to wash away, sapping influences, and excavation slope stability will be had a strong impact on, and layer of sand side slope surface protection simultaneously is difficulty comparatively.In recent years, country also begins corresponding ecological construction when strengthening the infrastructure construction dynamics, and country clearly proposes to strengthen the green channel construction.Therefore, a kind of layer of sand stable slope property that both guaranteed of active demand realizes green channel construction needs again, and construction technology is simple and practice thrift the new construction of construction investment, and meets environmental protection requirement.
The utility model content
The utility model technical problem to be solved provides a kind of layer of sand cut slope ecological protection structure, can solve washing away of layer of sand side slope effectively and slip and collapse and stability problem, and help plant and on the layer of sand side slope, grow.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The layer of sand cut slope ecological protection structure of the utility model; Comprise and be fixedly installed on the skeleton that intercepts water that excavation slope distributes as net shape on domatic; It is characterized in that: the said skeleton grid that intercepts water is interior along the permeable geotextiles of the domatic laying of excavation slope; The planting soil that backfill is used to plant plant in the permeable geotextile laying building-block, building-block.
Said excavation slope is domatic to be single-stage, and sloping height≤8m, ratio of slope be not suddenly in 1: 2.
Said excavation slope is domatic to be multistage, and every grade of sloping height≤8m, ratio of slope be suddenly in 1: 2, at different levelsly the platform that width is not less than 3m is set between domatic, platform sealing and catchwater is set.
The beneficial effect of the utility model is, can fine solution layer of sand side slope wash away to slip collapsed and stability problem, and helps plant and on the layer of sand side slope, grow, thereby plays effective green ecological protective action; Its job practices is simple, helps reducing construction costs; Compliance with environmental protection requirements is easy to apply.
Description of drawings
This manual comprises following four width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model layer of sand cut slope ecological protection structure;
Fig. 2 is the enlarged diagram of local A among Fig. 1;
Fig. 3 is the structural representation of the hollow core building block of the utility model layer of sand cut slope ecological protection structure;
Fig. 4 is the structural representation of the hollow core building block of the utility model layer of sand cut slope ecological protection structure;
Component shown in the figure, toponym and pairing mark: excavation slope is domatic 10, permeable geotextiles 11, platform 12, the skeleton 20 that intercepts water, building-block 21, planting soil 22.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
See figures.1.and.2, the layer of sand cut slope ecological protection structure of the utility model comprises being fixedly installed on the skeleton 20 that intercepts water that distributes as net shape on the excavation slope domatic 10.Lay permeable geotextiles 11 along excavation slope domatic 10 in said skeleton 20 grids that intercept water, permeable geotextiles 11 is laid building-block 21, the planting soil 22 that backfill is used to plant plant in the building-block 21.Said permeable geotextiles 11 is evened up in skeleton 20 grids that intercept water by building-block 21 compactings; It is domatic that permeable geotextiles 11 plays a part firm chiltern; Can fine solution layer of sand side slope receive to concentrate infiltration to wash away local sand and influence whole slope stability problem gradually; It is domatic that said building-block 21 plays a part firm chiltern, can fine solution layer of sand side slope face the empty stability problem that collapses that is prone to slip, backfill planting soil 22 in the said building-block 21; Help plant and on the layer of sand side slope, grow, thereby play effective green ecological protective action.
Said excavation slope domatic 10 can be a single-stage, and sloping height≤8m, ratio of slope be not suddenly in 1: 2.With reference to Fig. 1, said excavation slope domatic 10 also can adopt multistage, and every grade of sloping height≤8m, ratio of slope be suddenly in 1: 2, at different levelsly the platform 12 that width is not less than 3m is set between domatic, platform 12 sealings and catchwater is set.With reference to Fig. 1, the thickness of said planting soil 22 is identical with building-block 21 thickness, and its external surface and building-block 21, skeleton 20 and his like the water surface that intercepts water are smooth-going.Usually, the said thickness that intercepts water skeleton 20 is not less than 0.6m, and skeleton 20 spacings that respectively intercept water are not more than 4m.
With reference to Fig. 3 and Fig. 4, for ease of construction, said building-block 21 can adopt hollow six rib building blocks or hollow two six rib building blocks, adopts the cement mortar bonding between each building-block 21.The thickness of building-block 21 is not less than 0.1m usually.Said permeable geotextiles 11 single-block areas are not less than 4m
2, even up by building-block 21 compactings.
Some principles of the above the utility model layer of sand cut slope ecological protection structure that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
