Description

A protection body for highway cutting infiltration slope

Technical Field

The utility model relates to the field of highway slope protection, in particular to a protection body for a highway cutting seepage slope.

Background

In recent years, "ecological railways", "low-carbon roads" and "green airports" in China have become the trend of engineering construction, and have made higher requirements on aspects such as technical innovation, environmental protection and ground disaster prevention and control. The novel structure is mainly applied to river revetment at present at home, for example, the dry dike of the Changjiang river of yellow stone, the Jing river section under the Changjiang river, the Yangjiang river revetment section from Guilin to Yangshao, and the wading road section of the landslide control project of the Chongqing Fengjie terrace all adopt the structure form of a gabion retaining wall, and a good effect is achieved. In recent years, the method has also been applied to roadbed support engineering of roads, such as roadbed support of Wu ten roads and glalan roads, roadbed support of tibet highways and the like.

The supporting and protecting of the gabion used for the highway side slope in China has not yet been widely applied, although there are few successful case projects in road engineering, the anticorrosion technology of the reinforcing mesh for the supporting and protecting type in China internationally includes the defects, so that the durability of the gabion is poor, the problems of rusting of iron wires, breakage of check nets, sliding of stones and the like can not occur for a long time in use, the attractiveness of road appearance is influenced, and the stability of the road cutting side slope can not be guaranteed.

In addition, the site construction process of the traditional gabion protection technology is simple and low, the reinforcing mesh is assembled manually mainly by workers on site, stones are carried, time and labor are wasted, the problems of irregularity of the reinforcing mesh, gabion stacking deviation and other details are often caused, and the hidden danger is buried under the protection and retaining action of later engineering entities.

And the gravel cushion layer 5 is wrapped with a permeable geotextile 4.

And a kerbstone 3 is fixed at the edge of the gabion 1 at the bottommost layer of the protection body.

Rivets 11 extending out of the bottom of the gabion 1 are placed at the bottom of the gabion 1.

Gabion 1 comprises first net piece 6, second net piece 7 and third net piece 8, and a plurality of second net pieces 7 are the first group of cuboid and correspond two sides through assembling the installation of spiral hoop 10, constitute the cuboid second through two first net pieces 6 and organize and correspond two sides, constitute the cuboid third through two third net pieces 8 and organize and correspond two sides.

And a hoisting reinforcing hoop 9 is arranged at the junction of the second net piece 7.

The kerbstone 3 is provided with water permeable holes 301.

The utility model has the beneficial effects that: 1) the split gabion structure is adopted, the split gabion can be installed on site, and the split gabion is small in transportation volume and convenient to transport.

2) This device adopts the steel reinforcement gabion structure, and during the stone material that will accord with the particle diameter requirement was filled the gabion, had certain fender, antiskid, scour protection effect, can bear the destruction of harsh environment and climatic conditions to have the effect that fuses, promotes the view effect with the engineering environment.

Detailed Description

The technical scheme of the utility model is further explained by specific embodiments in the following with the accompanying drawings:

a protection body for highway cutting infiltration side slope that shows as in fig. 1 ~ 5 aims at providing a reliability, and security and strong protective structure of stability realize the protection to highway cutting infiltration side slope. The specific structure and operation are as follows.

The protection body uses gabion 1 as the carrier, adopts the net piece structure that can splice to form a cuboid structure, packs building stones 2 in the stone cuboid structure. The gabion 1 is made up of a first mesh 6, a second mesh 7 and a third mesh 8. The first net sheet 6 is a net sheet with a top surface and a bottom surface and adopts a single net sheet structure. The second meshes 7 form the front meshes and the rear meshes through the assembled spiral hoops 10. During assembly, the second net piece 7 is butted, and the assembled spiral hoop 10 is rotated to enter, so that fastening is realized. The third net 8 is a left net and a right net, and adopts a single net structure. The structure is integrally formed into a cuboid structure through assembling.

After the gabion 1 is spliced, the rivets 11 are firstly prevented, the rivet is of an inverted cone structure as shown in figure 5, and the rivets 11 extend out of the bottom surface of the gabion 1 after the rivet is placed. The rivets (11) serve to ensure stability of the gabion (1) after placement and prevent movement.

For make stable hoist and mount after placing building stones 2, it has hoist and mount to strengthen hoop 9 to consolidate through assembling spiral hoop 10 in the gabion 1 of cuboid, guarantees the intensity of gabion 1.

After the rivets 11 have been placed, the gabion 1 is filled with stones 2 of a specific size.

After the stone is put into with assembling of gabion 1, form a whole, the parcel has geotechnological cloth 4 that permeates water on the gravel bed course 5, and gabion 1 is placed on geotechnological cloth 4 that permeates water. The water-permeable geotextile 4 is a water-permeable geosynthetic material formed by needling or weaving synthetic fibers. The finished product is in cloth shape. The permeable geotextile 4 has excellent filtering, isolating, reinforcing and protecting effects, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance.

After the steps are completed, the gabion 1 is hoisted through hoisting equipment, and the gabion 1 is placed on the gravel cushion 5 in a stepped structure. When 1 hoist and mount of gabion, need hand over the installation each other with the gabion, set up kerbstone 3, the stability of the whole protective body of further assurance simultaneously at 1 border of bottom gabion is fixed.
