Abstract
The invention provides a high-strength special-shaped prestress combined support pile. The support pile is formed by first tubular piles and second tubular piles which are sequentially embedded at intervals. Each of each first tubular pile and each second tubular pile comprises an elliptical cylindrical concrete hollow pile and a reinforcement cage built in the elliptical cylindrical concrete hollow pile. Inner arc-shaped female ports symmetrically axially arranged are formed on two sides, namely two ends of the long axis of the ellipse, of each first tubular pile. Outer arc-shaped male ports symmetrically axially arranged are formed on two sides, namely two ends of the long axis of the ellipse, of each second tubular pile. The inner arc-shaped female ports are embedded into the outer arc-shaped mal ports to allow each second tubular pile to be connected with the corresponding first tubular pile in an embedded manner. A grouting hole axially arranged is formed in the middle of each outer arc-shaped male port of each second tubular pile. When each second tubular pile is connected with the corresponding first tubular pile, concrete is filled into the grouting holes. The high-strength special-shaped prestress combined support pile is mainly applicable to engineering support fields such as river wall support, apron support, coast support, and deep foundation pit support, traditional bricks are replaced, high strength and bending resistance are achieved, engineering quality is increased, and engineering safety is guaranteed.

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 object of the present invention is to provide a kind of plate brick that replaces for pattern foundation pit supporting structures such as river levee supporting, littoral bank protections, there is the high temperature prestressing combination soldier pile of larger intensity and flexing resistance.
To achieve these goals, high temperature prestressing combination soldier pile provided by the invention, by the first pile tube and the second pile tube, interval is chimeric successively forms;
The first pile tube and the second pile tube include elliptical cylinder-shape concrete hollow pile and are built in the reinforcing cage in concrete hollow pile;
The first pile tube both sides, in oval major axis two ends, are respectively equipped with axis of symmetry to female mouthful of the arc arranging;
The second pile tube both sides, in oval major axis two ends, are respectively equipped with axis of symmetry to the outer arcuate rim of the mouth arranging;
The female mouth of arc is embedded in outer arcuate rim of the mouth, and the second pile tube is connected with the first pile tube phase embedding;
In the middle part of the second pile tube outer arcuate rim of the mouth, be respectively equipped with the injected hole of axial setting;
The second pile tube fills concrete after being connected with the first pile tube phase embedding in injected hole.
Thus, the first pile tube and the second pile tube successively interval are mutually chimeric, form with integral body, replace plate brick for pattern foundation pit supporting structure, compare with plate brick, have higher intensity, have improved workmanship, have guaranteed engineering safety; In addition, injected hole is set, fills concrete and not only make the first pile tube and the second pile tube part connect closely in injected hole, effectively block water, soil overflow from connecting sewing simultaneously.
In some embodiments, the reinforcing cage of the first pile tube and the second 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, 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.
In some embodiments, the middle cavity of the concrete hollow pile of the first pile tube and the second pile tube becomes cylindrical, and on the major axis wall thickness on concrete hollow pile long axis direction and short-axis direction, minor axis wall thickness equates.Thus, guarantee the uniform distribution of concrete hollow pile intensity and weight.
In some embodiments, the long axis length of the first pile tube and the second pile tube is 300mm-1200mm.
In some embodiments, major axis wall thickness and minor axis wall thickness are 70mm-150mm.
High temperature prestressing combination soldier pile provided by the invention compared with prior art has the following advantages:
High temperature prestressing combination soldier pile provided by the invention, 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.In addition, it is rational in infrastructure, and by two oval PHC pile tubes successively snapping, snapping place connects closely, stability and safety, and the loss of effective anti-sealing, soil.
