Abstract
The invention relates to a reinforced core-enveloped structural slope protector, which mainly comprises a unidirectional geotechnological grid, fillings, an anti-aging plant-growing geotextile bag and connecting pieces. The slope protector is made from the fillings reinforced with the unidirectional geotechnological grid. The structural slope protector can obtain the raw materials from local resources and can be constructed with the earth material on the construction site, thus significantly saving energy; the reinforced materials of the structural slope protector has good durability; the structural slope protector also has the advantages of convenient construction, lower construction cost and the like.
Description
Technical field
The present invention relates to a kind of side slope protection body, relate in particular to a kind of geo-grid sheet reinforcement bank protection body.
Background technology
Existing reinforcement bank protection body mainly by geotechnological reinforcement material 1, plant immature soil worker bag 2, pitman 4, filler 6 four parts and form, the geotechnological reinforcement material 1 of dispersed placement in filler 6 with plant immature soil worker bag 2, the conventional reinforcement body of filler 6 common compositions.Its cardinal principle is to adopt reinforcement material that soil stabilization in the unstable slip circle envelope is handled.Existing reinforced slope and retaining wall technology have the following disadvantages: because the reinforcement body of design need pass the unstable slip circle envelope of inside configuration certain-length, the reinforcement length that requires is relatively large, and when the construction operation face has in limited time, need excavate the scope of operation at filler backfill position earlier to stay enough muscle materials to lay, just can construct then, will increase the excavated volume and the amount of fill of engineering like this, increase the difficulty of construction, cause project total cost higher.In that to run into slope protection works higher, during the narrow and small more situation of the scope of operation, use conventional reinforced structure and will make construction costs very high, constructional difficulties, even can't construct owing to can't satisfy the structural entity stability requirement.
Summary of the invention
Technical problem to be solved by this invention has provided a kind of reinforced core-enveloped structural slope protector, at the slope protection works height, and under the narrow and small situation of the scope of operation, but safe construction still.
Reinforced core-enveloped structural slope protector provided by the invention, comprise geotechnological reinforcement material 1, plant immature soil worker bag 2, pitman 4, filler 6, geotechnique's reinforcement material 1 and filler 6 alternately pressings, following one deck geotechnique reinforcement material 1 is connected tension with geotechnological reinforcement material 1 by pitman 4 with last layer, the described immature soil worker bag 2 of planting is wrapped between the adjacent up and down two-layer geotechnological reinforcement material 1 of described reinforced core-enveloped structural slope protector free face, be wrapped in geotechnique bag 3 adjacent counter between the two-layer geotechnological reinforcement material 1 up and down of described reinforced core-enveloped structural slope protector structure behind, and adjacent geotechnological reinforcement material 1 linked together by junction button 5.
As improvement of the present invention, described reinforced core-enveloped structural slope protector structure is provided with drainage network 7 behind and between the sloping body, and drainage network 7 is a kind of adrainage material.
As improvement of the present invention, described geotechnological reinforcement material 1 is mesh type or flaky material.
As improvement of the present invention, the described sack that definite size arranged of immature soil worker bag 2 of planting for adopting the durability synthetic materials to make, interior dress is ploughed and is planted soil and grass-seed; Described geotechnique's bag 3 woven bags of making for common synthetic materials, the existing earth material in filling job site.
As improvement of the present invention, filler 6 is the filler that carries out backfill reinforcement bag core structure according to the parameters selection of reinforcement bag core structure designing requirement, need be by backfilling of earthwork requirement compacting during backfill.
Reinforced core-enveloped structural slope protector of the present invention has utilized the soil principle that its supporting capacity improves under lateral deformation is tied condition, plant by geotechnological reinforcement material 1 and both sides that the soil body retrains in 3 pairs of bags of immature soil worker bag 2 and geotechnique's bag core structure bodies, make the dispersion soil body form the robust structure unit.When each firm block construction vertically is superimposed, formed the gravity retaining structure of a flexibility---slope sticking type reinforced soil retaining wall.The slope sticking type reinforced soil retaining wall can apply active force in protected side slope, improves the stability against sliding of side slope.Lay form because the present invention has changed reinforcement material, reduced the design length of reinforcement body.The present invention and existing conventional reinforced structure major different are the form that bank protection body structure behind anti-package is wrapped up in, thereby cut off unstable curved stroke.The bank protection body of this form of structure and concrete and stone masonry gravity retaining wall mechanics principle are similar, but changed the material of main part that is used for body of wall, the main body filler of this structure is earth material and reinforcement geotechnique material, and then the main body filler of two class formation form barricades is concrete and stone.This reinforcement bag heart bank protection body can freely be selected between 0 °～90 °.
Compare with existing reinforcement technology, the present invention has the low characteristics of engineering comprehensive cost, when the reinforcement technology construction of adopting routine, runs into when needing the former side slope of excavation to carry out the cloth muscle, substitutes the advantage that also has easy construction concurrently with the present invention.Now illustrate:
High 2 meters to build, long 100 meters escape canal is an example, and selecting the material parameter of banketing for use is γ=14kn/m
3, φ=10 °, levee crown evenly distributed load are got 10kpa, calculate the used operating expenses that adopts earth structure and reinforcement bag core structure respectively, carry out the construction cost expense at last relatively.
As calculated:
1. according to conventional reinforced structure way, then needing reinforcement length is 5.8 meters, and its every linear meter(lin.m.) Master Cost is as follows:
| Sequence number | Title material and specification | Unit | | Unit price | |
| 1 | Unidirectional geo-grid | m 2 | 30 | 10 | |
| 2 | Plant immature soil worker bag | Bar | 20 | 18.00 | |
| 3 | Pitman | |
3 | 15 | |
| 4 | Banket | m 3 | 11.6 | 15 | |
| Subtotal | Unit | 879 |
2. press reinforcement bag core structure way, the every linear meter(lin.m.) Master Cost of bank protection body is as follows:
| Sequence number | Title material and specification | Unit | | Unit price | |
| 1 | Unidirectional geo-grid | m 2 | 13 | 10 | |
| 2 | Plant immature soil worker bag | Bar | 20 | 18.00 | |
| 3 | Pitman | |
3 | 15 | |
| 4 | Geotechnique's bag | Bar | 20 | 1 | |
| 5 | Junction button | Individual | 5 | 0.85 | |
| 6 | | m | 3 | 2 | 15 |
| 7 | Connection cord | m | 8 | 0.45 |
| Subtotal | Unit | 592.85 |
Both compare: 592.85/879=67.45%.
By above comparative result as can be seen, adopt the saving of bag core structure engineering direct cost to reach 1/3, this does not also comprise because reduce the expense that amount of excavation is saved of opening.
