Abstract
The utility model provides a high-strength prestressed combination support pile. Cylindrical tube piles are sequentially arranged to form the high-strength prestressed combination support pile, the tube piles comprise cylindrical concrete hollow piles and reinforcement cages internally arranged in the concrete hollow piles, grouting holes are respectively, symmetrically and axially formed in two sides of each tube pile, namely two ends of each circular diameter, the section of each grouting hole is semicircular, the semicircular grouting holes of two adjacent tube piles are combined to form a circle, and concrete is filled into the grouting holes. The high-strength prestressed combination support pile is mainly applied to the field of engineering supports such as a river bank support, a wharf apron support, a seacoast revetment and a deep foundation pit support, traditional bricks are replaced, the support pile has high strength and bending resistance, engineering quality is improved, and engineering safety is ensured.
Description
Technical field
The utility model relates to a kind of pile tube, relates in particular to the high-strength prestressed combination supporting stake that a kind of intensity is large, the scope of application is wide and meet engineering demand.
Background technology
Along with the development of concrete technology, the technology of concrete tubular pile also reaches its maturity, except being applied to, industry, civilian construction, to be also widely used in each fields such as bridge, harbour, railway or hydraulic engineering.Pile tube comprises prestressed concrete pipe pile (PC pile tube), thin tubular piles produced by prestressed concrete (PTC pile tube), prestressed high-strength concrete pile (PH pile tube), centrifugal tubular pile with concrete of thin-wall steel pipe (TSC pile tube).
But in engineering support field, concrete tubular pile does not also relate to.
At present, utilize plate brick for engineering support, as: the fields such as river levee supporting, wharf apron supporting, littoral bank protection, deep foundation pit support.It is compared with concrete tubular pile, and its intensity and anti-bending strength are too late far away, therefore, adopts plate brick for engineering support, can not guarantee workmanship.
Therefore, need to open up the function of concrete tubular pile, make full use of concrete tubular pile.
Summary of the invention
The purpose of this utility model is to provide a kind of plate brick that replaces for pattern foundation pit supporting structures such as river levee supporting, littoral bank protections, has the high-strength prestressed combination supporting stake of larger intensity and flexing resistance.
To achieve these goals, the high-strength prestressed combination supporting stake that the utility model provides, is arranged and forms successively by cylindrical pile tube;
Pile tube comprises: cylindrical concrete hollow pile and be built in the reinforcing cage in concrete hollow pile;
Pile tube both sides, in round diameter two ends, are respectively equipped with axis of symmetry to the injected hole arranging, and it is semicircle that the cross section of injected hole becomes;
The semicircle injected hole of adjacent two pile tubes is combined into circle, fills concrete in injected hole.
Thus, pile tube arranges successively, and shape is in aggregates, replaces plate brick for pattern foundation pit supporting structure, compares with plate brick, has higher intensity, has improved workmanship, has guaranteed engineering safety; In addition, injected hole is set, fills concrete and not only make to connect closely between pile tube in injected hole, effectively block water, soil overflow from connecting sewing simultaneously.
In some embodiments, the reinforcing cage of pile tube is extended axially along concrete hollow pile by some, and the ring-shaped stirrup formation that circularizes the prestressed reinforcement of distribution and be welded on prestressed reinforcement periphery, and prestressed reinforcement is uniformly distributed or uneven distribution.Thus, according to different bending resistances, require to arrange radical and the distribution mode of prestressed reinforcement.
The high-strength prestressed combination supporting stake that the utility model provides compared with prior art has the following advantages:
The high-strength prestressed combination supporting stake that the utility model provides, be mainly used in engineering support, as: the fields such as river levee supporting, wharf apron supporting, littoral bank protection, deep foundation pit support, replace traditional plate brick, there is higher intensity and bending resistance, improve workmanship, guaranteed engineering safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the high-strength prestressed combination supporting stake of a kind of embodiment of the utility model.
Fig. 2 is the sectional view of pile tube in the high-strength prestressed combination supporting stake shown in Fig. 1.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail to explanation.
Fig. 1 and Fig. 2 have schematically shown the high-strength prestressed combination supporting stake according to a kind of embodiment of the utility model.
As depicted in figs. 1 and 2, high-strength prestressed combination supporting stake of the present utility model, is arranged and forms successively by cylindrical pile tube 11.Pile tube 11 both sides, in round diameter two ends, are respectively equipped with axis of symmetry to the injected hole 2 arranging, and it is semicircle that the cross section of injected hole 2 becomes; The semicircle injected hole 2 of adjacent two pile tubes is combined into circle, fills concrete 4 in injected hole 3.
As shown in Figure 2, pile tube 11 comprises: cylindrical concrete hollow pile 1 and be built in the reinforcing cage in concrete hollow pile 1.The reinforcing cage of pile tube 11 is extended axially along concrete hollow pile 1 by some, and the ring-shaped stirrup formation that circularizes the prestressed reinforcement 3 of distribution and be welded on prestressed reinforcement 3 peripheries, prestressed reinforcement 3 requires to arrange radical and the distribution mode of prestressed reinforcement according to different bending resistances.
In sum, the high-strength prestressed combination supporting stake that the utility model provides, be mainly used in engineering support, as: the fields such as river levee supporting, wharf apron supporting, littoral bank protection, deep foundation pit support, replace traditional plate brick, there is higher intensity and bending resistance, improved workmanship, guaranteed engineering safety.
