Abstract
The utility model relates to a novel steel bar concrete precast pile, for resolving the problem of prior art which is hard to sink pile on foundation of sand or broken pebbles. The technical scheme of the utility model comprises that the pile body of prior hollow pile is arranged with water outlets. The utility model can be used for hollow steel bar concrete precast piles in any shape. The utility model can sink pile on the foundation of sand or broken pebbles.
Description
(1) technical field:
The utility model relates to a kind of new reinforcing steel bar concrete precast pile.
(2) background technology:
The precast reinforced concrete piles that sinks in the existing building engineering when being sand or crushed gravel as ground, often can't carry out with hammering or static pressure pile-sinking merely, should be aided with pile jetting usually, and sinking of pile by water jet with interior be the best towards interior row's method.This stake slime water in interior process of carrying out pile sinking towards interior row's method is to discharge from the top of stake.Rise out the height h of the water surface (referring to river face or phreatic surface) when excessive when stake, the efficient of discharging slime water is very low, and h value is greater than 30 meters, and slime water just row has not come out, and this method is also just of no use, and pile sinking has also just become insurmountable hang-up at this moment.
(3) summary of the invention:
The utility model has solved prior art is difficult to pile sinking on the ground of sand or crushed gravel technical barrier.
The technical solution of the utility model is as follows: the pile body at existing hollow pile is provided with weep hole.
The utlity model has following advantage:
1. before the horizontal weep hole of pile body buried, slime water was discharged from horizontal weep hole, and this moment, the h value was little, spoil disposal slurry efficient height, pile sinking effect height.
2. after the horizontal weep hole of pile body buried, row's slime water was discharged into the pile body outside by horizontal weep hole on the part, and the sand around the moistening stake can reduce pile side resistance greatly.
3. because this stake can be given full play to the effect towards row, can reach desirable embedded depth equally with low power water pump and air compressor.
4. because end resistance and pile side resistance are reduced to littler degree, also can smoothly stake be sunk to the pile monkey of little energy or the less Static pressure pile driver of static pressure and to require the degree of depth.
5. Zhuan maximum embedded depth can reach 70～80 meters.
6. plant takes and electricity charge saving.
(4) description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the A-A sectional view.
Fig. 3 is the B-B sectional view.
Fig. 4 is the C-C sectional view.
(5) specific embodiment:
Embodiment 1:
As shown in Figure 1: 1 is pile body, and 2 is the centre bore of stake, and 3,4 is the horizontal weep hole of pile body.The utility model is on the pile body 1 of the precast reinforced concrete piles of existing hollow horizontal weep hole 3,4 to be set.Shown in Fig. 2,3,4: weep hole 3,4 is interspersed about being about every interval 2000mm on the pile body 1, and the aperture of weep hole 3,4 is about 40mm.
The utility model structure is applicable to the hollow steel bar concrete precast pile of any profile.
Claims (4)
1 one kinds of precast reinforced concrete piles that are provided with centre bore is characterized in that: the pile body at the precast reinforced concrete piles that has hollow now is provided with weep hole.
2 precast reinforced concrete piles according to claim 1: it is characterized in that: weep hole is horizontal weep hole.
3 precast reinforced concrete piles according to claim 1: it is characterized in that: weep hole is interspersed about being about every interval 2000mm on the pile body 1.
4 precast reinforced concrete piles according to claim 1: it is characterized in that: the aperture of weep hole is about 40mm.
