The utility model discloses can improve soil body mechanical properties, soil body stability need not to remove the reconstruction retaining wall behind the enhancement wall, pile foundation construction safe and reliable.
Description
Technical field
The utility model relates to technical field of buildings, is specially a kind of bridge pile foundation structure of constructing within the scope of reinforced earth retaining wall.
Background technology
Reinforced earth retaining wall adds lacing wire in soil, utilizes the rubbing action between lacing wire and soil, improves the deformation condition of the soil body and improve the engineering properties of the soil body, thus reaching the object of the stable soil body.Reinforced earth retaining wall is made up of filler, the lacing wire of arranging in filler and shingle nail three part.Because reinforced earth bulkhead is flexible structure, it has good resistance to deformation and the ability of earthquake motion, saves occupation of land simultaneously, and handsome in appearance, cost is lower, therefore applies to widely on embankment section and water conservancy project shore protection barricade.Existing reinforced earth bulkhead to be constructed pile foundation, because pile foundation position needs to cut off lacing wire Effect of Materials stability, the conventional soil compaction effect rushing (brill) hole pouring pile pile foundation construction and shock effect, all may cause larger potential safety hazard to present situation retaining wall structure safety and stability.Therefore be necessary to study a kind of bridge pile foundation structure being adapted at construction within the scope of reinforced earth retaining wall.
Utility model content
The purpose of this utility model is to provide a kind of bridge pile foundation structure of constructing within the scope of reinforced earth retaining wall, to realize supporting bridge Upper Structure.
For achieving the above object, the utility model is by the following technical solutions:
A bridge pile foundation structure within the scope of reinforced earth retaining wall, comprises pile foundation main body, steel pile casting, steel sheet pile props up mask, compaction grouting hardened layer, plain concrete sclerosis confining bed; Described pile foundation main body is club-footed holing pile, and described pile foundation main body is positioned at the distance≤300cm below road surface; Described steel pile casting is around being arranged on pile foundation main body outer rim; Described steel sheet pile props up mask and is positioned at pile foundation main body side, and its top is concordant with road surface; Described steel sheet pile props up between mask and pile foundation main body and fills compaction grouting hardened layer; Described stake top mark height above reinforced earth retaining wall upper surface arranges plain concrete sclerosis confining bed.
Wherein, described compaction grouting hardened layer is selected cement list liquid to starch in injection injected hole and is formed, the every 1.0m of described injected hole
2arrange 1, in quincuncial arrangement.
Preferably, described plain concrete sclerosis confining bed is obliquely installed outside wall, and horizontal wall inscription is 1 ° ~ 2 °, and thickness is 20cm ~ 50cm.
After adopting technique scheme, the utility model has following effect: the utility model is adapted at reinforced earth retaining wall scope and constructs, adopt the mode of compaction grouting can improve soil body mechanical property, soil body stability after reinforcement wall, avoid or reduce the destruction to stable region lacing wire, reduce soil compaction effect and the shock effect of pile foundation construction, guarantee the reinforced earth retaining wall safety of construction period and operation phase, stablize.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, the utility model discloses the bridge pile foundation structure in a kind of reinforced earth retaining wall 6 scope, comprise pile foundation main body 1, steel pile casting 2, steel sheet pile prop up mask 3, compaction grouting hardened layer 4, plain concrete sclerosis confining bed 5.
Pile foundation main body 1 is club-footed holing pile, and pile foundation main body 1 is positioned at the distance≤300cm below road surface; Steel pile casting 2 is around being arranged on pile foundation main body 1 outer rim; Steel sheet pile props up mask 3 and is positioned at pile foundation main body 1 side, and its top is concordant with road surface; Steel sheet pile props up between mask 3 and pile foundation main body 1 and fills compaction grouting hardened layer 4; The above reinforced earth retaining wall upper surface of stake top mark height arranges concrete sclerosis confining bed 5 of being always or usually as specified.Element concrete sclerosis confining bed 5 is obliquely installed outside wall, and horizontal wall inscription is 1 ° ~ 2 °, and thickness is 20cm ~ 50cm.Work progress of the present utility model is as follows:
1, construction guard fender forms place, sets steel sheet pile supporting formation steel sheet pile and props up mask 3, feel understand reinforcement material scope and present situation situation to present situation reinforced earth retaining wall 6 along road side.
2, height of pile top (≤300cm) is excavated in boundary of works area, and remove the reinforced earth retaining wall 6 of more than corresponding height, and C20 element concrete sclerosis Seal treatment is built to construction surface, and look for slope, namely be obliquely installed outside wall, horizontal wall inscription is 1 ° ~ 2 °, and formin concrete sclerosis confining bed 5, is beneficial to draining.
3, within the scope of pile foundation, compaction grouting cure process is carried out to the earth's surface soil body and form compaction grouting hardened layer 4.Compaction grouting hardened layer 4 is selected cement list liquid to starch in injection injected hole and is formed, water/binder ratio 0.5 ~ 0.6, water glass incorporation 3%, the every 1.0m of injected hole
2arrange 1, in quincuncial arrangement.
4, steel pile casting 2 retaining wall fetches earth while follow up, and end pore-forming is expanded rapidly in position at the bottom of stake.
5, descending reinforcing cage, continous pouring concrete, forms pile foundation main body 1, completes pile foundation construction.
The utility model, in the stability under loading mechanism of reinforced earth retaining wall 6, is avoided or reduces the destruction to stable region lacing wire, adopts the modes such as slip casting to improve soil body mechanical property, soil body stability after reinforcement wall, and rebuild retaining wall without the need to removing, pile foundation construction is safe and reliable.
The above, be only the utility model preferably detailed description of the invention, is anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
