Description
Technical field
The present invention relates to slope greening fields more particularly to a kind of highway code to build slope planting structure and its construction work
Skill.
Background technique
In current large-scale engineering process of construction, ecological afforestation engineering technology is greatly developed, especially high
In fast highway planting engineering, by vast scientific research and the discussion of engineering staff and practice, many new greening techniques are developed, such as
Soil environmental protection repair process device technique, highway shield soil structure etc..These technologies overcome the list of Traditional project technology
One property and inefficiencies, realize the combination of ecological afforestation and highway.However, the prior art is mostly only directed to newly
In the research and development and technological innovation of material, shorter mention to highway code builds the technical study and utilization of side slope.
When carrying out side slope code block at present, hard stone code of the stone application partial size greater than 35cm that code is built is built, and stone is as far as possible
Rule, code masonry block are close to as far as possible, are closely knit, without obvious cavity, absent-mindedness phenomenon.Although can all carry out nailing when being laid with metal mesh
With the fixation of assistant metal net, but due to the firm deficiency of rock layer, it still will appear the case where nail slides in stone, cause
The soil moved in improve the original layer on upper layer also will appear offset, and offset is built up to a certain degree, and the risk on landslide is also just gradually increased, and there are safety
Hidden danger.
Summary of the invention
The object of the present invention is to provide a kind of highway codes to build slope planting structure and its construction technology, stable structure
Property is good, and soil moved in improve the original layer is not easy to slide, and the risk on landslide is greatly reduced.
To achieve the above object, the present invention provides a kind of highway code block slope planting structure, including stone layer, described
Stone layer is equipped with multiple hexagonal stiffening frames；Each stiffening frame includes that six roots of sensation skeleton and the six roots of sensation are same for connecting
The reinforcing bar of adjacent skeleton in stiffening frame；Skeleton includes the inserted link of lower part and at least two gear stone portions in portion disposed thereon, keeps off stone
Portion end protrudes from the side wall of inserted link, and it is inserting for 1.5 times of end reinforced sectional area or more that sectional area is equipped in each gear stone portion
Hole, it is end reinforced to be located in the jack and be equipped with elastic filler between the two；It is successively set from the bottom to top above stiffening frame
There are metal mesh and soil moved in improve the original layer.
As a further improvement of the present invention, the jack is located on the top surface in gear stone portion, and reinforcing bar includes being located at its both ends
Bending part, the bending part is plugged in the jack, is filled with the elastic filler between the two；Each reinforcing frame
Apical side height of the upper level of stone layer not higher than gear stone portion in frame.
As a further improvement of the present invention, the free state of the reinforcing bar is arc-shaped.
As a further improvement of the present invention, the skeleton further includes the pillar being connected to above gear stone portion, the pillar
The grid on metal mesh is passed through from the bottom up.
As a further improvement of the present invention, the top of the pillar is higher than the middle part of soil moved in improve the original layer.
As a further improvement of the present invention, stone portion, three gears stone are kept off there are three being all provided on each skeleton
Portion is uniformly distributed around the axis of inserted link.
To achieve the above object, the present invention also provides a kind of highway codes to build slope planting structure construction technology, including
Following steps: carrying out slope surface treatment, forms more smooth stone layer；The skeleton interval is inserted on the stone layer of slope surface,
And reinforcing bar is protruded into the jack in gear stone portion；Elastic filler is injected into jack, makes skeleton and steel after elastic filler solidification
Muscle, which is fixedly connected, constitutes the stiffening frame；After being laid with metal mesh above stiffening frame, then soil moved in improve the original base of sowing grass seeds by duster on metal mesh
Material forms soil moved in improve the original layer.
As a further improvement of the present invention, when being laid with the metal mesh, the pillar above the gear stone portion is allowed to wear
Cross the grid on metal mesh；Reinforcing bar in stiffening frame, which forms metal mesh, to be supported, and metal mesh is located at stiffening frame middle part
It is sunk under the gravity of soil moved in improve the original substrate to stone layer upper surface position.
Beneficial effect
Compared with prior art, highway code of the invention builds the advantages of slope planting structure and its construction technology are as follows:
1, the inserted link of skeleton and gear stone portion are inserted on stone layer, can be to adding since gear stone portion protrudes from inserted link side wall
Gu the building stones at six angles play certain restriction effect in frame.The building stones at six angles are by after limiting displacement, in stiffening frame
Building stones by middle section are then not easy building stones sliding occur also by multidirectional limit, occur to reduce top soil moved in improve the original layer
The probability of sliding.When skeleton, which is inserted in, connects reinforcing bar on stone layer, it is difficult to accomplish to ensure that spacing is exactly accurate between each skeleton, and
By allowing the jack sectional area in gear stone portion to be 1.5 times of end reinforced sectional area or more, can facilitate end reinforced into gear stone portion
On jack in, it is easy for installation.Meanwhile after the completion of reinforcing bar is connected with skeleton, due to end reinforced slotting with skeleton gear stone portion
What is filled between hole is elastic filler, even if slope surface has part deformation after work progress or completion, can also allow that reinforcing bar end
Portion carries out a degree of movement in jack, reduces pressure between the two or pulling force, reduces the risk that structure is destroyed.
2, bending part is plugged in the jack in gear stone portion, and the upper level of stone layer is not higher than in each stiffening frame
The apical side height in stone portion is kept off, then reinforcing bar forms metal mesh and supports, and metal mesh is located at stiffening frame centre position in soil moved in improve the original base
It is sunk under the gravity of material to stone layer upper surface, the entire metal mesh of slope surface forms the recessed structure of part convex portion, then
Soil moved in improve the original layer bottom surface also constitutes rough structure, further decreases soil moved in improve the original layer and the probability slid occurs, improves its stable structure
Property.
3, the free state of reinforcing bar is arc-shaped, then after connecting framework, entire hexagon stiffening frame has certain quilt
The surplus compressed or be stretched, overall structure have a degree of elasticity, certain stiffening frames are avoided to go out because of unbalance stress
The case where existing local plastic deformation.
4, the pillar on skeleton passes through the grid on metal mesh from the bottom up, and the grid width of metal mesh is pillar width
1.5-1.7 times or so, positioning action can be played to metal mesh, metal mesh is not easy to slide.And pillar also can be to soil moved in improve the original layer
Play position-limiting action.
5, three gear stone portions are uniformly distributed around the axis of inserted link on skeleton, then two adjacent stiffening frames can be allowed to share a side
Edge allows the stiffening frame of entire side slope in honeycomb structure.
Through the following description and in conjunction with the attached drawings, the present invention will become more fully apparent, these attached drawings are used to explain the present invention
Embodiment.
