Abstract
A prestressing pipe pile for buildings comprises a pile body (1) and a pile head (2) arranged at the lower end of the pile body (1). The prestressing pipe pile is characterized in that the diameter of the pile head (2) is larger than that of the pile body (1); and the value range of difference value H1 is between 10 cm and 40 cm; and a plurality of raised lines (3) are arranged on the lateral surface of the pile body (1); the value range of the distance H2 of the raised lines (3) higher than the pile body is between 3 cm and 7 cm; the raised lines (3) are uniformly distributed on the pile body (1); and the value range of distance H3 between the two adjacent raised lines (3) is between 20 cm and 50 cm. The utility model has the advantages of simple structure, low cost, good effect, effective acceleration of the drainage and the solidification of soil layers, and improved strength of foundation soil.
Description
Technical field:
The utility model relates to a kind of pile for prestressed pipe, and is especially a kind of simple in structure, with low cost, can promote the soil layer draining to solidify, and improves the pile for prestressed pipe for building of foundation soil strength.
Background technology:
When carrying out building operations, the pile body of applied various pile for prestressed pipe and pile crown diameter equate, the problem that is produced is that the bearing capacity of its end is little, and when the soil property in construct area is softer, uses this pile tube and bring certain potential safety hazard can for later construction; If, use the high pile for prestressed pipe of bearing capacity, improved again and bought the cost that Building Material House needs, and then improved construction costs and construction cost in order to adapt to soil property.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, and cost is low, and is effective, can effectively promote the soil layer draining to solidify, and improves the pile for prestressed pipe for building of foundation soil strength.
Technical solution of the present utility model is: a kind of pile for prestressed pipe for building comprises pile body 1 and is arranged on the pile crown 2 of pile body 1 lower end that it is characterized in that: the diameter of described pile crown 2 is greater than the diameter of pile body 1, its difference H
1Span be 10-40 centimetre.
The side of described pile body is provided with raised line 3, and raised line 3 is higher than the distance H of pile body part
2Span be 3-7 centimetre.
The quantity of described raised line 3 is a plurality of, is distributed on the pile body 1, the distance H between per two adjacent raised lines 3
3Span be 20-50 centimetre.
The utility model is compared with prior art, has following advantage:
Equal conditions down can be by a relatively large margin the supporting capacity of raising stake end, thereby reduced the cost of pile foundation, save construction cost; After pile crown enters ground, in the space around the pile body, fill sandstone or cobble, can promote the draining of soil layer to solidify, improve foundation soil strength, effectively guaranteed construction quality and safety, be specially adapted to bearing stratum soft clay area use preferably.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: a kind of pile for prestressed pipe for building, comprise pile body 1, be provided with pile crown 2 in the lower end of pile body 1, the shape of the cross section of pile crown 2 can be circular, square or polygon, the diameter of pile crown 2 is greater than pile body 1, the difference H of the two
1Span be 10-40 centimetre, be good with 25 centimetres;
Be provided with raised line 3 in the side of pile body 1, the distance H of raised line 3 outstanding pile body parts
2Span be 3-7 centimetre, be good with 5 centimetres;
The quantity of raised line 3 is a plurality of, and concrete number can decide according to the length of pile body 1, and raised line is distributed on the pile body 1, and the distance H between per two adjacent raised lines 3
3Span be 20-50 centimetre, be good with 35 centimetres.
The course of work of the pile for prestressed pipe for building of the utility model embodiment is as follows: at first pile tube is squeezed among the soil layer 4, because the diameter of pile crown 2 is bigger than pile body 1, therefore after pile crown 2 enters bearing stratum 5, just can form the difference H that a width approximates pile crown 2 and pile body 1 around the pile body 1
1Sandstone or cobble are inserted in the space in the middle of this space, compress, and just finish the piling process.
Claims (3)
1, a kind of pile for prestressed pipe for building comprises pile body (1) and is arranged on the pile crown (2) of pile body (1) lower end, it is characterized in that: the diameter of described pile crown (2) is greater than the diameter of pile body (1), its difference H
1Span be 10-40 centimetre.
2, pile for prestressed pipe for building according to claim 1 is characterized in that: the side of described pile body (1) is provided with raised line (3), and raised line (3) is higher than the distance H of pile body part
2Span be 3-7 centimetre.
3, pile for prestressed pipe for building according to claim 2 is characterized in that: the quantity of described raised line (3) is a plurality of, is distributed on the pile body (1) distance H between per two adjacent raised lines (3)
3Span be 20-50 centimetre.
