Description

Cantilevered structure road and building method thereof in conjunction with H type friction pile punishment landslide
Technical field
The invention belongs to building structure and field of road, particularly to a kind of cantilevered structure road and building method thereof punishing landslide on slip mass slope, mountain area in conjunction with H type friction pile.
Background technology
In road engineering in a mountainous area designs, due to special landform and geological environment, it is frequently encountered location, landslide.Often the bigger landslide of harm is reasonably taked through scheme comparison the measure of passing round.If but after the scheme comparison of sufficient line position, the cost that detours is too big, should consider landslide is renovated.Building road in slide area generally should not adopt embankment pattern to pass through in main sliding section, adopts cutting pattern to pass through at antiskid Duan Buying.In prior art, building road, generally first landslide is punished on slip mass, the many employings in punishment landslide are removed slip mass, are administered surface water and groundwater, lightening and adverse pressure and arrange the measures such as retaining structure.And the form being generally adopted embankment or cutting passes through slip mass.When adopting cutting pattern by slip mass, if built road foundation wider width, necessarily to carry out cutting slope in backer side, when road is positioned at landslide antiskid section, high cutting-slope reduces the stability on landslide, and high cutting-slope need to tackle domatic protection mutually simultaneously, protection works amount is huge, invests significantly high.High cutting-slope destroys natural environment simultaneously, and landscape effect is very poor.
Summary of the invention
It is an object of the invention to provide a kind of cantilevered structure road in conjunction with H type friction pile punishment landslide on slip mass slope, mountain area, landslide can be punished, road is built again in conjunction with Landslide Treatment and on slip mass slope, high embankment is not only avoided during construction, and it is convenient, safe and reliable, economical and practical to construct, save land area, reduce the road construction impact on natural environment simultaneously.
For achieving the above object, technical scheme is as follows: a kind of cantilevered structure road in conjunction with H type friction pile punishment landslide, it is characterized in that: on slip mass slope, be provided with H type friction pile, at H type friction pile, cantilevered structure is set by the friction pile of ditch side, oblique prestress anchorage cable is set between described cantilevered structure and slip mass, using cantilevered structure, longitudinal guidance tape is set as supporting, cantilevered structure is provided with anticollision barrier by ditch lateral edges, longitudinal guidance tape arranges road surface structare layer, described cantilevered structure, longitudinal guidance tape, anticollision barrier and road surface structare layer are collectively forming the cantilevered structure road on slip mass slope.
According to a preferred embodiment of the invention, described H type friction pile includes backer side friction pile and leans on ditch side friction pile and connect backer side friction pile and the transverse strut by ditch side friction pile.
According to a preferred embodiment of the invention, one end, cantilevered structure backer side arranges oblique prestress anchorage cable, and described oblique prestress anchorage cable anchors into the Rock And Soil under potential deep implication face.
It is an object of the invention to provide a kind of building method in conjunction with the cantilevered structure road on H type friction pile punishment landslide on slip mass slope, mountain area, landslide can be punished, road is built again in conjunction with Landslide Treatment and on slip mass slope, high embankment is not only avoided during construction, and it is convenient, safe and reliable, economical and practical to construct, save land area, reduce the road construction impact on natural environment simultaneously.
For achieving the above object, technical scheme is as follows: the building method of a kind of cantilevered structure road in conjunction with H type friction pile punishment landslide, it is characterised in that described construction method comprises the following steps: A. construction backer side friction pile;B. construction is by ditch side friction pile;C. build backer side friction pile and by the armored concrete transverse strut between the friction pile of ditch side, form H type friction pile;D. construction is by the cantilevered structure on the friction pile of ditch side;E. the oblique prestress anchorage cable of stretch-draw;F. to form, for the longitudinal guidance tape of supporting laying, road sections of encorbelmenting with the cantilevered structure of H type friction pile one;G. complete the construction of the gutter of backer side, at cantilevered structure outer ledge, anticollision barrier is installed, complete the pavement structure construction of road overall with scope.
The method have the advantages that newly-built on the slope of slip mass or widen road, the Landslide Treatment in conjunction with H type friction pile arranges the cantilevered structure with prestress anchorage cable and longitudinal guidance tape is collectively forming road.H type friction pile considerably increases the bending rigidity of stake, can bear bigger slope thrust body, and landslide can effectively be administered.Prestressed cable anchorage Rock And Soil under potential deep implication face, it is applied with the external force stoping its downslide to slip mass, improve the stability on landslide, change the irrational cantilevered stress of general friction pile, stake long cross-sectional area with pile body has been dramatically reduced.Avoid huge excavation and fill yard and side slope that high embankment on slip mass causes simultaneously or embankment props up gear protection works, there is obvious economic benefit.Reduce and especially adopt deep slope or main sliding section to adopt high roadbed to have a strong impact on the potential safety hazard of Landslide Stability in antiskid section.Avoid the considerable influence to natural ecological environment.
