Description

Stablize board-like anchor pile retaining structure

Technical field

The utility model relates to the retaining structure of geotechnical engineering, particularly applies to the anchor pile retaining structure of long cantilever section in high embankment closing slope or the landslide control, large soil pressure (or Thrust of Landslide).

Background technology

Along with the development of society, a lot of high embankment side slopes has appearred, simultaneously because the restriction of engineering specifications, much engine requests employing retaining structure closing slopes in the engineering.On the other hand, some stable Rock And Soil of occurring in nature along with the variation of the external conditions such as geology, the hydrology, becomes understable, unstable.Under aforementioned engineering specifications, can relate to and use the long anchor pile of cantilever segment, effect soil pressure or Thrust of Landslide thereon is also larger, and this has proposed very high requirement to anchor pile.Yet the cantilevered anchor pile is as a kind of cantilever structure, and is stressed and deformation performance is relatively poor.Especially anchor pile is when the soil layer anchoring, be difficult to reach " horizontal movement of place, ground stake should not greater than 10mm " of code requirement, if surpass, just conventional coefficient of subgrade reaction can not adopt, must carry out reduction, coefficient of subgrade reaction diminishes after the reduction, and it is larger to draw pile deformation, forms vicious circle, control the stake horizontal movement of place, ground so usually adopt increase stake cross section or increasing buried depth, final economic effect is not good, and the buried depth of stake is excessive, constructional difficulties.At present, the gear measure in high embankment closing slope or the landslide control mainly contains following several:

The stake board wall is developed by anchor pile, when the embankment side slope adopts the cantilevered anchor pile to prop up gear, between the stake breast boards is set, in order to the soil body behind the protected apron.The embankment, the cutting that can be used for general area, soaking district and earthquake zone prop up gear, also can be used for a landslide gear protection.Early 1970s takes the lead in being applied in the trunk railways such as a Liu Tielu, Line of Nankun Railway.

Prestressed anchor pull-type (anchor cable) stake board wall is that the cantilever segment at anchor pile applies prestressing force, with the engineering measure of the gear protection that solves high slope.It is a kind of structure of drawing facility to be combined as a whole on stake board wall and anchor.Typical engineering has Line of Nankun Railway stone stockaded village prestressed anchor sheet-pile retaining wall engineering.

Pile foundation joist retaining wall is the combining form of retaining wall and stake, is connected by joist.Be mainly used in solving the lower problem of bearing capacity, retaining wall is generally weight formula or gravity, and pile foundation is anchor pile.In the geotechnical engineering field, this gear form is widely used.

The anchor pile of said structure under certain engineering boundary condition, can relate to that cantilever segment is long, soil pressure or Thrust of Landslide is large, do not have stable anchor to draw the engineering specifications such as rock mass after the stake.Inevitably calculate the stake of heavy in section, long anchoring section, its result is very uneconomical, and difficulty of construction is also very large.

The utility model content

Technical problem to be solved in the utility model provides a kind of board-like anchor pile retaining structure of stablizing, and is out of shape the difficult problems such as excessive with the long cantilever that runs in the solution conventional design, large soil pressure or Thrust of Landslide, place, soil layer anchor pile ground.Optimize the anchor pile cross section, improve the safety of retaining structure, reduce construction costs.

The technical scheme that its technical problem that solves the utility model adopts is as follows:

Of the present utility modelly stablize board-like anchor pile retaining structure, comprise the anchor pile that the interval arranges, the bottom of anchor pile is embedded in the anchoring Rock And Soil, it is characterized in that: the stake top of described anchor pile is provided with the with it fixed setting panel that is integrated and horizontal stable plate, and steadying plate laterally inwardly extends into the embankment side slope and bankets or come down in the gliding mass.

The beneficial effects of the utility model are: effectively solve the difficult problems such as the long cantilever that runs in the conventional design, large soil pressure or Thrust of Landslide, the distortion of place, soil layer anchor pile ground be excessive, optimize the anchor pile cross section, improve the safety of retaining structure, reduce construction costs; The retaining structure system is simple, stressed clear, and exploitativeness is strong.
