Abstract
A cantilever-type counterfort-type retaining wall of a pile foundation effectively solves the problems of overturning and slipping of a cantilever-type counterfort-type retaining wall and has the advantages of being good in structural integrity, simple in structure, convenient to construct and the like. The cantilever-type counterfort-type retaining wall of the pile foundation comprises the cantilever-type counterfort-type retaining wall (10) and is characterized in that row-up pile foundations (20) are laid below the cantilever-type counterfort-type retaining wall (10) along the length direction of the cantilever-type counterfort-type retaining wall (10) at intervals, and the cantilever-type counterfort-type retaining wall (10) is in rigid connection with the top ends of the row-up pile foundations (20).
Description
Technical field
The utility model relates to cantilevered, counterfort retaining wall, particularly the cantilevered, the counterfort retaining wall that adopt of a kind of high-fill roadbed closing slope.
Background technology
Cantilevered, counterfort retaining wall in the embankment closing slope since its to have closing slope effective, outward appearance is good, thereby be widely used, but it has clear and definite service condition, as hold up the arm-type barricade should not be greater than 10m, and should not adopt at unfavorable geology and the area more than the earthquake motion peak accelerator 0.2g, Cantilever Retaining Wall requires highly should not surpass 6m; Cantilevered, counterfort retaining wall deformation failure cause mainly due to its overturning or slip resistance analysis, antiskid or bearing capacity of foundation soil deficiency simultaneously.For giving full play to the superiority of cantilevered, counterfort retaining wall, in the urgent need to cantilevered, counterfort retaining wall are improved, propose that structural integrity is good, wide accommodation, construction technology be simple, and meet the new structure of environmental requirement.
The utility model content
Technical problem to be solved in the utility model provides a kind of pile foundation cantilevered, counterfort retaining wall, with effective solution determine cantilevered, counterfort retaining wall overturning or slip resistance analysis, antiskid problem, has the characteristics such as structural integrity is good, simple in structure, easy construction.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Pile foundation cantilevered of the present utility model, counterfort retaining wall, comprise cantilevered, counterfort retaining wall, it is characterized in that: pile foundation in a row is laid along its length direction interval in the below of described cantilevered, counterfort retaining wall, and the top of cantilevered, counterfort retaining wall and pile foundation in a row is rigidly connected.
The beneficial effects of the utility model are, have effectively solved certainly cantilevered, counterfort retaining wall overturning or slip resistance analysis, antiskid problem, particularly on plastid poorly or in the earthquake zone and the problem such as overturning or slip resistance analysis, antiskid, the bearing capacity of foundation soil of cantilever when higher be lower; Structural integrity is good, and is simple in structure, easy construction, and wide accommodation, and meet environmental requirement, have wide popularizing application prospect.
Description of drawings
This manual comprises such as next width of cloth accompanying drawing:
Fig. 1 is the utility model pile foundation cantilevered, counterfort retaining wall schematic cross-sectional view.
Component shown in the figure, toponym and corresponding mark: cantilevered, counterfort retaining wall 10, pile foundation 20 in a row, outside pile foundation 21, inboard pile foundation 22.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, pile foundation cantilevered of the present utility model, counterfort retaining wall, comprise cantilevered, counterfort retaining wall 10, campshed base 20 is arranged to along its length direction interval cloth in the below of this cantilevered, counterfort retaining wall 10, and cantilevered, counterfort retaining wall 10 are rigidly connected with the top of pile foundation 20 in a row.Utilize pile foundation 20 to provide skid resistance, anchorage and bearing capacity for cantilevered, counterfort retaining wall 10, utilize cantilevered, counterfort retaining wall 10 to carry out the embankment closing slope.
In a row the stake of each pile foundation is long according to the foundation condition adjustment in the pile foundation 20, when the ground condition is better, pile foundation and ground shared upper load, long the getting the small value of stake. when the ground condition is relatively poor, can adopt pile foundation 20 to bear upper load, sufficient bearing capacity and settlement requirement is covered with in stake.
With reference to Fig. 1, in a row pile foundation 20 is made of the outside pile foundation 21, the inboard pile foundation 22 that arrange along cantilevered, counterfort retaining wall 10 width intervals usually, wherein outside pile foundation 21 is laid in the below, cantilever bottom of cantilevered, counterfort retaining wall 2, and cantilever and the base plate of cantilevered, counterfort retaining wall 10 satisfy force request.In a row the spacing along cantilevered, counterfort retaining wall 10 length directions is 5～10m in the pile foundation 20, or determines according to Force Calculation.
Some principles of the above just explain through diagrams the utility model pile foundation cantilevered, counterfort retaining wall, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
