Abstract
The utility model discloses a concrete vertical bearing pile with overhanging wedge fin plates. The bearing pile is formed by the method that a precast hollow pile and a hollow pile are driven into soil layers and backfilled with cement mortar; the cross section of a pile block at the position with a distance of 0.5M-1.0M to the pile tip forms a square hollow shape or a circular hollow shape; horizontal through holes are alternately laid out and arranged on the pile wall on two opposite sides at the middle lower part of a hollow pile body; movable wedge fin plates with wedge-shaped inner ends and flat heads or arc head outer ends are inserted in the through holes, and the wedge fin plates are I-shaped steel, or channel steel, or T-shaped steel. The utility model can enhance the vertical bearing capacity of the piles without increasing the diameter and the length of the piles. The utility model has advantages of simple method, convenient implementation and low cost.
Description
Technical field
The utility model relates to a kind of vertical bearing peg of concrete with overhanging wedge shape wing plate.Belong to the building structure in industry and civilian construction, bridge, the port works field.
Background technology
Present many engineerings all adopt concrete pile to improve the vertical bearing capacity of building foundation in the field.The diameter or the length of side of stake are big more, or stake is long more, and then Zhuan vertical bearing capacity is big more, and correspondingly Master Cost and piling expense are also high.Cross when thick or long when stake in some cases, piling is difficulty also.
Can not increase the diameter and the length of stake, take a kind of fairly simple measure to improve the vertical bearing capacity of stake?
Summary of the invention
The purpose of this utility model is to provide a kind of vertical bearing peg of concrete with overhanging wedge shape wing plate, and this bearing peg can improve the vertical bearing capacity of stake effectively under the situation of diameter that does not increase stake and length.
For achieving the above object, the utility model is realized by following technical proposals: be driven into the vertical bearing peg of concrete with overhanging wedge shape wing plate that the backfill cement mortar constitutes in stake behind the soil layer by precast hollow stake and hollow pile, it is characterized in that, hollow or round hollow from the stake cross section side of being of pushing up apart from tip 0.5m～1.0m position to stake, on the pile lining of two opposite side of the middle and lower part of hollow pile body, offer the through hole of horizontal direction alternately, insert the inner end in the through hole and be wedge shape, the outer end is the activity wedge shape wing plate of straight head or circular arc head.
The cross section, aperture of horizontal through hole is I shape on the above-mentioned pile lining, or " U " type of falling, or T-shape.
Above-mentioned wedge shape wing plate is an i iron, or channel-section steel, or the T-shape steel, and two blocks of wedge shape wing plates on the same elevation pile lining measure-alike is symmetry and places, and their length respectively be half of a stake diameter or a length of side.
Superiority of the present utility model is: need not increase the diameter of stake and the vertical bearing capacity that length just can significantly improve stake, method is simple, and it is convenient to implement, and expense is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a work progress schematic diagram of the present utility model.
1 is hollow pile lining among the figure, and 2 is vertical hollow hole and cement mortar, and 3 is horizontal through hole, and 4 is wedge shape wing plate, and 5 is the tapered steel pipe in bottom.
The specific embodiment
An embodiment is as follows for the utility model: the vertical bearing peg of concrete with overhanging wedge shape wing plate as shown in Figure 1, the stake cross section is a square, the length of side is 0.55m, the long 15m of the section of burying stake, pile center is the vertical hollow hole of the cylinder of diameter 0.3m, is establishing horizontal through hole mutual vertically in couples and place the wedge shape wing plate made from i iron, the long 0.27m of wedge shape wing plate on two cross sections of stake bottom 1.0m and 1.5m, the wide 0.30m of wing plate, the high 0.20m of web.
Work progress of the present utility model such as Fig. 2 show, after stake is driven in the foundation soil, from the vertical hollow hole of stake, insert the tapered steel pipe in bottom of an external diameter 0.28m, apply impact force to steel pipe, outwards extrude 0.14m with placing each wedge shape wing plate of horizontal through hole, extract steel pipe then, with cement mortar with vertical hollow hole in the stake and horizontal through hole shutoff.
After handling like this, stake bottom loaded area has increased by 55.5%.For the stake that bearing capacity is provided by the stake bottom fully, the bearing capacity that then is equivalent to stake has improved 55.5%; For the stake that stake side-friction force and bearing capacity of pile tip respectively account for half, then Zhuan bearing capacity improves 27.8% at least, increases the favorable factor of back stake side-friction force increase because consider stake bottom bearing cross-section in analyzing.As seen this utility model is very significant to the effect of the vertical bearing capacity of raising concrete pile.
Claims (3)
1. vertical bearing peg of concrete with overhanging wedge shape wing plate, be driven into behind the soil layer by precast hollow stake and hollow pile that the backfill cement mortar constitutes in stake, it is characterized in that, hollow or round hollow from the stake cross section side of being of pushing up apart from tip 0.5m～1.0m position to stake, on the pile lining of two opposite side of the middle and lower part of hollow pile body, offer the through hole of horizontal direction alternately, insert the inner end in the through hole and be wedge shape, the outer end is the activity wedge shape wing plate of straight head or circular arc head.
2. according to the described vertical bearing peg of concrete of claim 1, it is characterized in that the cross section, aperture of horizontal through hole on the pile lining is I shape with overhanging wedge shape wing plate, or " U " type of falling, or T-shape.
3. according to the described vertical bearing peg of concrete of claim 1 with overhanging wedge shape wing plate, it is characterized in that wedge shape wing plate is an i iron, or channel-section steel, or T-shape steel, two blocks of wedge shape wing plates on the same elevation pile lining measure-alike, be symmetry and place, their length respectively is half of the stake diameter or the stake length of side.
