Abstract
The utility model is a fat pile precast driven pile in the building foundation zone, which also comprises a pile body of the precast driven pile similar to the prior art, and is characterized in that the lower end of the pile body of the precast driven pile is the fat pile with the diameter larger than the diameter of the pile body by 5-50cm, and the outer side of the pile body has the thickness of 3-25cm and is filled with sands or pebbles. The utility model can greatly increase the bearing capacity of the pile end of the driven pile and reduce the fabrication cost of the pile foundation; and the outer side of the pile body is filled with sands or pebbles and has a certain thickness, which can facilitate water drainage, earth layer solidifying and foundation soil strengthening. The utility model is applied to the building foundation in earthy areas in the bearing stratum.
Description
The utility model relates to building field, relates in particular to the building foundation field.
At present, in the building foundation engineering, pre cast pile is widely used with its reliable in quality both at home and abroad, yet no matter stake of the existing pre cast pile side of being or pile tube are equal diameter from top to bottom, therefore, bearing capacity of pile tip is little.
The purpose of this utility model is to improve bearing capacity of pile tip greatly, reduces the pile foundation cost, and promotes the soil layer draining to solidify, and improves foundation soil strength.
The purpose of this utility model realizes by following technical measures, the utility model building foundation band stake major part pre cast pile is the same with prior art, all include the pre cast pile pile body, it is characterized in that in pre cast pile pile body lower end being the stake major part of diameter greater than pile body diameter 5-50cm, is back-up sand or the cobble of thickness 3-25cm in the pile body outside.Stake major part herein is plain concrete or steel bar concrete, and stake major part cross section is circular or square or polygon, and the stake major part is connected with insertion or electric welding with pile body.During pile sinking, because pile body diameter is less than the stake diameter at butt end, sand or cobble are just inserted along the stake and the gap of soil, until filling up.
The utility model compared with prior art has following advantage: can improve the bearing capacity of pile tip of driven pile greatly, reduce the pile foundation cost; The pile body outside is certain thickness back-up sand or cobble, is beneficial to draining, solidifies soil layer, improves foundation strength.The present invention is applicable to the bearing stratum building foundation of soft clay area preferably.
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 upper strata (1), (5), (6), stake major part (4) one ends are coated with in the tube chamber (7) of clay insertion tube stake pile body (2), at stake week heap sand, with pile driver it is squeezed in the soil layer (1), along with the sinking of pile body (2), sand (3) is just inserted the space between pile body (2) and the soil layer (1), when stake major part (4) enters bearing stratum (5) surface or certain depth, stop piling, and get final product after the space filled sand (3).
Claims (1)
1, utility model building foundation band stake major part pre cast pile is the same with prior art, all include the pre cast pile pile body, it is characterized in that in pre cast pile pile body lower end being the stake major part of diameter greater than pile body diameter 5-50cm, is back-up sand or the cobble of thickness 3-25cm in the pile body outside.
