Abstract
The utility model provides a construction foundation three-dimensional high-strength compound pile foundation, which contains a reinforced concrete pile and a top foundation as the same as the prior art. The utility model is characterized in that the reinforced concrete piles are alternatively distributed with cement mixing piles or small square and short piles; the piles are not connected with the top foundation; a mattres pad layer is arranged between the pile top and the top foundation. The utility model has the advantages of lowering pile foundation construction cost, reducing building sedimentation, improving vibration-proof grades of buildings; therefore, being suitable for construction foundation in soft soil areas.
Description
The utility model relates to building field, relates in particular to the building foundation field.
At present, the base form that adopts of China's building foundation field is three kinds of natural ground, composite foundation and pile foundations.Shanghai City capital construction commission has developed " settlement Control composite pile foundation " (Shanghai City " basic design specification of the foundation " in 1999) between composite foundation and pile foundation at local weak soil geology.This composite pile foundation makes stake thrust the bearing stratum certain depth earlier under load by anchoring into top basis with the long reinforced concrete pile of stake and forming jointly with it, allows the soil under basic bear built-loading jointly again.Through facts have proved that this composite pile foundation saves 30% cost than pile foundation, but settlement of building often surpasses 10cm, easily causes differential settlement, and building minor axis seismic resistance calculation does not reach 7 required degree requirementss for fortification against earthquake of area, Shanghai.
The purpose of this utility model is the intensity that strengthens foundation soil from three dimensions, makes stake and inter-pile soil bear built-loading jointly simultaneously, reaches and both reduces the pile foundation cost, reduces building settlement again, and can satisfy seismic resistance calculation.
The purpose of this utility model is to realize by following technical scheme: building foundation three-dimension high-strength composite pile foundation is the same with prior art, all include reinforced concrete pile and basis, top, it is characterized in that cloth cement agitation pile or little side stake stub between between the reinforced concrete pile, stake is not connected with the basis, top, establishes mattress layer between stake top and basis, top.The long 5-20m of stub herein, mattress bed thickness 8-30cm herein is made up of artificial rubble and sand.
The utility model compared with prior art, has following conspicuous advantage: by increase the intensity of soil from three dimensions, the foundation soil distortion is further reduced, both saved pile foundation cost 30-40%, again building settlement is controlled at 1-5cm, owing to be provided with mattress layer, seismic resistance calculation reaches 8 degree and sets up defences.The present invention is applicable to the building foundation of soft clay area.
Description of drawings:
Fig. 1 is the generalized section of an embodiment of the present utility model.
An exemplary embodiments of the present utility model such as Fig. 1: on the place of forming by soil layer (8), (9), (10), earlier reinforced concrete pile (7) is depressed into boulder bed (9) as bearing stratum by pile press, again by mixing pile machine construction cement mixing pile (5), shop embedding stake slabstone (4) between stake (5), (7), repave mattress layer (3) then, and by prior art pouring top basis plain concrete bed course of C10 (2) and raft plate (1).
