Abstract
The utility model discloses an offset-prevention type composite foundation structure, comprising a plurality of piles vertically arranged in a foundation in a mesh shape, wherein a cushion layer is paved on the top of each pile body and internally provided with a geogrid, each pile body is internally provided with a reinforcement cage, the upper end of each reinforcement cage is connected with the corresponding geogeid together, and the outer circumferential surface of each pile body is provided with a reinforcing structure for increasing a pressure bearing area between each pile body and soil. The offset-prevention type composite foundation structure disclosed by the utility model is simple in structure and convenient to use and has the advantages that not only are the shear resistance and bending resistance of the pile bodies increased, but also offset is prevented effectively, the anti-sliding stability of the composite foundation of the plurality of pile bodies is enhanced, and the settlement deformation resistance is increased.
Description
Technical field
The utility model relates to the capital works technical field, is a kind of anti-skew formula composite foundation structure concretely.
Background technology
At present; In flusch and the huge thick soil layer, often present soft hard structure down, generally in construction project; With last soft top layer as ground; At this moment need use composite foundation, composite foundation is usually used in the engineerings such as railway, highway, harbour and building, bears the ground that covers load jointly through the pile body and all foundation soils of pile body that are arranged in the ground.Bed course is generally depended in the distribution of composite foundation king-pile body stress, and GSZ generally is set in bed course, and sharing of soil layer stress is one of key factor of control composite foundation sedimentation and resistance to overturning.The position of pile body is controlled than being easier in the general foundation engineering, but in the last soft top layer such as soft foundation, owing to squeeze the influence of soil or soil excavation construction; The situation of pile body offset takes place easily, and the stress of putting aside in the soil like this is increasing, because GSZ is not connected with pile body; Only bed course is connected with pile body, and GSZ does not receive the constraint of pile body like this, not only causes the relative position of pile body to be difficult to confirm; Thereby cause the skew of pile body; And,, make inter-pile soil bear bigger load so can't stress effectively be delivered on the pile body owing to produce moderate finite deformation under the loading last covering; Therefore reduced the flexural strength of pile body, and made composite foundation produce bigger sedimentation.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art; Provide a kind of simple in structure; Easy to use, the shearing resistance and the bending resistance of pile body can not only be improved, and displacement can be effectively prevented; Increase the stability against sliding of a plurality of pile body composite foundations, thereby improve the anti-skew formula composite foundation structure of the ability of anti-sedimentation and deformation.
Its technical scheme is: anti-skew formula composite foundation structure; Comprise and be the latticed many piles body that is vertically set in the ground; The top of said pile body is equipped with bed course, is provided with GSZ in the said bed course, is provided with reinforcing cage in the said pile body; The upper end of said reinforcing cage and said GSZ link together, the external peripheral surface of said pile body be provided with can increase and soil between the ruggedized construction of bearing area.
Said ruggedized construction comprises and the supporting plate that is arranged on the pile body external peripheral surface that be provided with reinforcing rib between said supporting plate and the said pile body, said supporting plate and reinforcing rib and said pile body are in aggregates by reinforcing bar and concrete pouring.
After having adopted technique scheme; The beneficial effect that the utility model is obtained is: the utility model is simple in structure; Easy to use, the shearing resistance and the bending resistance of pile body can not only be improved, and displacement can be effectively prevented; Increase the stability against sliding of a plurality of pile body composite foundations, improved the ability of anti-sedimentation and deformation.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
Shown in accompanying drawing; Anti-skew formula composite foundation structure comprises being the latticed many piles body 1 that is vertically set in the ground that the top of said pile body 1 is equipped with bed course 2; Be provided with GSZ 3 in the said bed course 2; Be provided with reinforcing cage 4 in the said pile body 1, the upper end of said reinforcing cage 4 and said GSZ 3 link together, the external peripheral surface of said pile body 1 be provided with can increase and soil between the ruggedized construction of bearing area.
Pile body 1 top is provided with shearing resistance and the bending resistance that reinforcing cage 4 can effectively improve pile body 1; GSZ 3 is connected the lateral displacement that can retrain single pile body 1 with the top of pile body 1; Increase the stability against sliding of a plurality of pile body 1 composite foundations; Simultaneously can also give full play to the high characteristic of its tensile strength, upper load can be transferred on the high pile body of bearing capacity 1 effectively, therefore can further improve the vertical bearing capacity of composite foundation.
Said ruggedized construction comprises and the supporting plate 5 that is arranged on pile body 1 external peripheral surface, is provided with reinforcing rib 6 between said supporting plate 5 and the said pile body 1, and said supporting plate 5 is in aggregates by reinforcing bar and concrete pouring with reinforcing rib 6 and said pile body 1.Through supporting plate 5 can improve and soil layer between bearing area; And prevent that pile body 1 from taking place laterally or length travel; Thereby the ability with stronger anti-sedimentation and deformation, and can improve the structural strength of pile body 1 through reinforcing rib 6, improved the shearing resistance and the bending resistance of pile body 1.
During use, can adopt and casting reinforcedly behind the manually digging hole process pile body 1, when making, reinforcing cage 4 can be set on the top of pile body 1 with concrete; The grade makes ground be lower than the top of pile body 1, lays the rubble that constitutes bed course 2 more on the ground; Rubble is laid to concordant with pile body 1 top; Lay one deck GSZ 3 on the surface at rubble and pile body 1 top then, and reinforcing cage 4 and GSZ 3 are linked together, re-lay rubble afterwards through connector; Constitute bed course 2 like this, thereby accomplish whole construction course.
The utility model is simple in structure, and is easy to use, can not only improve the shearing resistance and the bending resistance of pile body, and can effectively prevent displacement, increases the stability against sliding of a plurality of pile body composite foundations, improved the ability of anti-sedimentation and deformation.
