Description
Technical field
The technical fields such as water conservancy, highway and water and soil conservation are the utility model is related to, are more specifically composite foundations
Reinforcement gabion baffling structure.
Background technology
During the filling of the engineerings such as shore protection levee body, highway subgrade, Dumping Sites, generally use barricade resists pressure of banketing
Power.When above-mentioned engineering construction is located at coastal region, river and lake seashore, mollisol area, deep covering layer area, earth formation is more
It is made of Extra-fine sand, silt, silty clay, muck soil, traditional barrier wall structure can not meet filling body after itself and its wall
Stability requirement, must be combined using other modes with barricade, the pressure of banketing after sharing lood wall.
Traditional barricade material is concrete or stone masonry, and concrete guard wall is related to concrete production, transports, pours, applies
Construction equipment is more, complex procedures；Stone masonry barricade needs manually to build by laying bricks or stones, expends substantial amounts of manpower, speed of application is slow.Chinese patent
CN104674841B puts block stone using machinery and quickly forms retaining wall, although improving the degree of barricade mechanized construction, adds
The fast speed of application of barricade, but it faces same problem with concrete guard wall, stone masonry barricade：When running into above-mentioned geology bar
During the poor situation of part, since foundation bearing capacity is relatively low, the filling body after barricade and its wall will occur larger deformation or even
Unstable failure, therefore should not directly be used on mollisol, deep covering layer ground.Chinese patent CN205116214U,
Although CN104389320B, CN103321243B are using bored concrete pile, micro-steel pile, screw rod pile, rotary churning pile, mixing pile to barricade
Ground has carried out consolidation process, but above-mentioned pile body is plain concrete or reinforced concrete structure, complicated construction technique, work of constructing
Phase is grown, and project cost is high.
When filling body height is higher after barricade, pressure of banketing only is resisted in itself by barricade, can cause bricklaying constructed object
Product is huge while higher to the requirement for bearing capacity of ground, and construction cost is also higher.
The content of the invention
The purpose of the utility model is to overcome the shortcoming of above-mentioned background technology, and propose composite foundation reinforcement gabion
Barrier wall structure.
The purpose of this utility model is implemented by following technical solution：Composite foundation reinforcement gabion baffling structure,
It includes composite foundation, reinforced gabion, TGXG, loaded filter and filling body composition；The composite foundation be located at ground with
Lower and be made of more vibro-replacement stone columns, multiple reinforced gabions are piled up in the top of the composite foundation, described
Reinforced gabion on the inside of be provided with filling body, the lower part of the filling body is provided with TGXG, in the reinforcing bar stone
Loaded filter is provided between cage and the filling body.
In the above-mentioned technical solutions：The outer ledge of the vibro-replacement stone column along the reinforced gabion expands arrangement 2-
3 campsheds.
In the above-mentioned technical solutions：The reinforced gabion is formed using site welding and piles up into triangle；It is and adjacent
The reinforced gabion between the fissure of displacement pile up and use it is U-shaped nail be linked to be an entirety.
In the above-mentioned technical solutions：The reinforced gabion includes keel reinforcing bar and fabricated bar, the fabricated bar
Between using galvanized wire bind；The keel reinforcing bar be located at the outside of the fabricated bar and be welded to each other into one it is whole
Body.
In the above-mentioned technical solutions：The TGXG layered arrangement is and described in the inside of the filling body
Filling body is stacked from bottom to top along the bottom of the TGXG；The TGXG lateral length is more than twice of institute
The height for the reinforced gabion stated.
In the above-mentioned technical solutions：The loaded filter is in tilted layout along on the inside of the reinforced gabion, and described is anti-
The upper end of filtering layer is flushed with the upper end of the reinforced gabion.
The utility model has the following advantages that：1st, steel bar stone cage retaining wall can adapt to certain deformation, especially soft
It is more more notable than the advantage of rigid structure barricade in the case of soil base or deep covering layer ground.
2nd, steel bar stone cage retaining wall can be process using reinforcing bar and block building stones at the construction field (site), easy for construction, speed of application
It hurry up.
3rd, consolidation process is carried out to barricade ground using vibro-replacement stone column, live metaling can be made full use of, with concrete
Stake or reinforced concrete pile are compared, and without purchasing reinforcing bar, cement, construction technology is easy, quick.When stake footpath is 60cm, stake is a length of
During 8m, concrete-pile comprehensive unit price is 66 yuan/m, and vibro-replacement stone column comprehensive unit price is 45 yuan/m, and pile body cost can reduce by 30%
More than.
The 4th, TGXG is set in the filling body after barricade, it is possible to increase the globality and non-deformability of filling body, energy
Enough reduce the soil pressure suffered by wall, so as to reduce barricade bricklaying volume and its requirement for bearing capacity to ground, save engineering
Investment.
