Abstract
A pretensioned prestressing wedge-shaped concrete tubular pile is suitable for products of foundation infrastructure, and consists of a steel bar, a hooping bar and concrete, the diameter at one end of the tubular pile is larger, the diameter at the other end of the tubular pipe is smaller, the pile body has a wedge-shaped structure, and the steel bar and the hooping bar in the tubular pile are fixedly connected. In the utility model, the contact area between the pile body and the soil is increased, the side resistance of the pile body is improved by compacting the soil a plurality of times, and the safety quality of the building is improved.
Description
Technical field
The utility model relates to a kind of building foundation field and uses product, specifically a kind of pretensioned prestressing wedge shape concrete tubular pile.
Background technology
Concrete tubular pile in the realm of building construction, be widely used at present as the basis; But present employed concrete tubular pile is the identical isometrical pile tube of two ends diameter; Earlier drill through isodiametric hole during use at predeterminated position; Again concrete tubular pile is put into the hole, in some heavy constructions or facility, then can once more it be tamped until lithosphere, make it have higher supporting capacity.Diameter is identical up and down but the isometrical concrete tubular pile of this kind is owing to it, and the diameter in its preset hole must be identical with this pile tube diameter, if preset bore dia then pile tube less than normal can't get into, rocks if preset can produce after hole then pile tube bigger than normal gets into.Just because of this, after isometrical concrete tubular pile got into preset hole, any change can not take place in the soil body density around it, and the pile body collateral resistance is a steady state value.In some heavy constructions or facility, need to improve the pile body collateral resistance and squint to prevent building or facility, the used isometrical concrete tubular pile of this kind then can't address the above problem at present.
Summary of the invention
In order to solve the problem that the existing concrete pile tube exists; The utility model provides a kind of pretensioned prestressing wedge shape concrete tubular pile; This pretensioned prestressing wedge shape concrete tubular pile not only can have advantages of high bearing capacity, and can effectively improve the collateral resistance of pile body.
The utility model solves the technical scheme that its technical problem adopted: it is to be made up of reinforcing bar, stirrup and concrete, and an end diameter of pile tube is bigger, and other end diameter is less, and pile body is wedge structure, and reinforcing bar is fixedly connected with stirrup in the pile tube.The utility model can increase the contact area of the pile body and the soil body under the situation that does not reduce the concrete pipe pile bearing capacity, utilize pile body the repeatedly extruding of the soil body to be improved the collateral resistance of pile body.
The beneficial effect of the utility model is: not only have advantages of high bearing capacity, increase the contact area of the pile body and the soil body, utilize pile body the repeatedly extruding of the soil body to be improved the collateral resistance of pile body; Thereby reduction production cost of products; Product structure is simple, and cost is low, is prone to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the cross-sectional view of the utility model.
Fig. 2 is the cross-sectional view of the 2nd kind of embodiment of the utility model.
Code description among the figure: 1,1 '-concrete; 2,2 '-reinforcing bar; 3,3 '-stirrup; 4-segmentation pile tube; 5-segmentation pile tube; 6-segmentation pile tube.
As shown in Figure 1, the utility model is made up of concrete (1), reinforcing bar (2) and stirrup (3), and the upper end diameter of pile tube is bigger, and lower end diameter is less, and pile body is wedge structure, and reinforcing bar (2) is fixedly connected with stirrup (3) in the pile tube.Because the two ends diameter of the utility model is different, and pile body is wedge structure, thus when boring preset hole, then can bore one with the utility model in the diameter diameter identical than small end; And after pile tube being put into preset hole, through the compacting pile body, then can pile body be inserted in the preset hole; In the compacting process, because the upper diameter of pile tube can be increasing, former preset Kong Zehui is expanded; And then push the soil body on every side, thus improved the density of pile body surrounding soil, improved the collateral resistance of pile body.
Fig. 2 is the cross-sectional view of the 2nd kind of embodiment of the utility model; This embodiment calculates the size of each segmentation pile tube earlier respectively according to the construction needs; Each segmentation pile tube (4), (5), (6) that to produce then connect, and are applicable to the deep foundation ditch operation.
Need to prove that what the utility model adopted is hollow-core construction, but can adopt solid construction according to the present technique scheme in actual conditions, can further improve the bending resistance of pile tube.
Claims (1)
