Description
Technical field
The present invention is the horizontal bolt anchorage of a kind of multistage bank protection and bottom bank protection draining mixed structure, belongs to Highway Slope and protects
Slope technical field of structures.
Background technology
Project post-evaluation has slope protection and retaining structure protection two classes.The conventional measure of slope protection has mortar or tabia
Etc. wiping one's face, whitewash, pneumatically placed concrete, mortar flag stone revetment, shotcrete bank protection, anchor and spray net bank protection etc..Such measures is mainly in order to protect
The domatic rock decay of excavation slope peels off, broken fall and a small amount of falling rocks fall the phenomenons such as block.The side slope protected, should have enough
Stability, then first props up gear and protects for unstable side slope.The type of retaining structure is more, such as retaining wall, anchored bolt retaining wall, resists
Sliding pile etc..The existing protective action of these retaining structures, plays the role of again to reinforce slope body.Use engineering measure bank protection, often too
Pursue intensity effect, destroy ecological natural, landscape effect difference, and As time goes on, concrete surface, mortar flag stone face
Can weathering, aging, even damage, the later stage renovates costly.
Using phytobiocoenose Gu Po, keeping the effect of soil to have certain limit, it is not usually involved in deep soil
Cave in or the slip of extremely thick and heavy soil layer.For high gradient slope, if not taking engineering measure, plant growth medium is then difficult to invest
Domatic, plant just cannot grow.Therefore, slope vegetation protection technology must be that plant measures combines with engineering measure, plays the two
Respective advantage, just can efficiently solve slope project protection and the contradiction of environmental destruction, both ensure that stablizing of side slope,
The fast quick-recovery of slope vegetation can be realized again, reach the harmonious coexistence of mankind's activity and natural environment.
Afforestation project bank protection is to use lived plant to realize the purpose of bank protection, and its function embodiment is following several sides
Face:
(1) soil conservation function
The vertical root system of plant may pass through the loose weathered layer of slope body shallow-layer, anchors on the more stable rock-soil layer in depths,
Play the effect of prestressed anchor.Dogstail, legume and undershrub have obvious soil to strengthen making at underground 0.7～1.5m
With the anchorage effect of Tree root system can have influence on the deeper rock-soil layer in underground.The herbaceous plant of shallow root, its root system is in soil mid-game
The wrong joint of root, makes slope soil become the composite of soil and grass roots, and grass roots, just as the prestressed three-dimensional reinforcement material of band, makes the soil body strong
Degree is greatly improved.The unstability of side slope and the size close relation of slope body water pressure, rainfall is the important of induction mass erosion
One of factor.Plant is by absorbing and rising slope internal water, the pore water pressure reducing the soil body, and the shearing resistance improving the soil body is strong
Degree, and then promote stablizing of side slope body.Having the domatic of vegetative coverage, rainfall, before arrival is domatic, is just dammed by vegetation, is planted
To the raindrop of landing and concentration plume, be there is significantly pin by cauline leaf can act on, slope water erosion can be effectively prevented.Covering of vegetation
Lid also can be effectively prevented sandstorm.
(2) environmental functional is improved
As time goes on, function is constantly strengthened for the individuality of plant or group, is other animals and plants by Self-variation
Life condition is provided, improves ecological environment around.Such as, strengthen water retention, provide life for animal, insect etc. are biological
Space, alleviates miniclimate, purifies air, reduction noise etc..
(3) health care, educational level are improved
By the configuration of different plant varieties and different shaping, different ecoscape effects can be shown.Phytobiocoenose
The view being formed can make people experience mental toughness, calmness, gracefulness, comfortable etc..
In a word, taking engineering reinforcement measure, to mitigation, the domatic unstability building the initial stage and erosion effect are preferable, effect
Significantly, but, As time goes on, aging, the corrosion of reinforcing bar of atmospheric disintegration of rocks, concrete, intensity reduces, and effect is also got over
It is poorer to come.Use slope vegetation protection then on the contrary, effect when starting is weak, but with the growth of plant, breeding, intensity increases
Add, can be increasing to the effect mitigating domatic unstability and erosion.In addition, slope vegetation protection also have one significant excellent
Point, it can recover the ecological environment being destroyed because of engineering construction.
Content of the invention
It is an object of the invention to solve the classification of existing Highway Slope domatic in the case of running into different soil, especially road
The soil at base top is stable soil, domatic classification bank protection domatic for domatic carrying out reinforcing to bank protection during detrimental soil, draining, to
Realize construction of the highway, use during stabilization and reinforcement, promote the use quality of highway and service life.
For achieving the above object, the technical solution used in the present invention is the horizontal bolt anchorage of multistage bank protection and bottom bank protection row
Water mixed structure, this mixed structure is divided into bank protection horizontal bolt anchorage system and bottom bank protection drainage system；The horizontal anchor pole of bank protection
Hardened system is arranged on the middle and upper part of multistage bank protection, and bottom bank protection drainage system is arranged on the bottom of multistage bank protection.
Bank protection classification between road surface (1) and roadbed bottom surface (5) is arranged, and the bank protection section of each middle and upper part uses cement anchor
Block (2), horizontal anchor pole (3) are reinforced；The ply stacking angle of cement anchor block (2) is equal with the bank protection gradients at different levels of road surface (1),
In the top of the embedded subordinate in cement anchor block (2) the bottom bank protection of every grade of bank protection；Cement anchor block (2) is domatic with bank protections at different levels
Between be provided with horizontal anchor pole (3)；Be parallel to each other between each horizontal anchor pole (3) layered arrangement.
Bottom bank protection drainage system includes drainage groove (4), water guide groove (6)；Bank protection slope bottom water guide groove (6) connection
Top (7) and roadbed bottom surface (5)；Drainage groove (4) is arranged on the toe at the bottom of bank protection Nei and parallel with roadbed bottom surface (5), gutter
Groove (4) is connected with water guide groove (6).
The degree of depth in the embedded subordinate in described cement anchor block (2) bottom bank protection is the 1/9-1/ of cement anchor block (2) length
6。
The inner surface of described bottom bank protection drainage system is coated with cement mortar protective course.
The gradient between top, bank protection slope, described bottom (7) and water guide groove (6) is 1%-3%.
Compared with prior art, the present invention has the advantages that.
1st, this structure is by being coated with cement sand bed at the inner surface of bottom bank protection drainage system, in order to stop outer flowing water
Penetrate into roadbed, it is ensured that the service life of roadbed and use quality.
2nd, this structure is provided with cement anchor block and each horizontal anchor pole being evenly arranged, each anchor pole phase along the surface of classification bank protection
It is arranged in parallel mutually, and the end of horizontal anchor pole is fixed on anchoring cement block, effectively increases the slope stability of classification bank protection
Property.
3rd, the bottom bank protection drainage system of the present invention is compound with bank protection horizontal bolt anchorage system arranges, effectively can reduce ground
The impact on roadbed stability for the face draining, this structure construction is simple, and Practical Performance is very good.
