Abstract
The utility model discloses a post-grouting concrete pre-stressed hollow square pile. A central through hole running through the whole post-grouting concrete pre-stressed hollow square pile is arranged in the center of the concrete pre-stressed hollow square pile in the longitudinal axis direction of the post-grouting concrete pre-stressed hollow square pile; the cross section of the post-grouting concrete pre-stressed hollow square pile is in a square structure with circular arc-shaped periphery; the cross section of the central through hole of the post-grouting concrete pre-stressed hollow square pile is square; and the geometric dimensions of sections at the internal periphery and the external periphery of the post-grouting concrete pre-stressed hollow square pile in the whole longitudinal axis direction are identical. According to the utility mode, a grouting pipe is pre-embedded in the prefabrication process of the post-grouting concrete pre-stressed hollow square pile, and the post grouting technique can be carried out after the pile foundation pile-sinking construction is finished, so that the physical-mechanical property of the soil body is changed, the load-bearing capability of the pile body is improved, and the connection between piles is also improved.
Description
Technical field
The utility model relates to the improvement of grouting behind shaft or drift lining concrete pre-stress hollow square pile in the building field and the prefabricated production of cast-in-place concrete structure post, particularly a kind of grouting behind shaft or drift lining concrete pre-stress hollow square pile.
Background technology
Mostly the existing concrete hollow square pile is prefabricated units, and after pile sinking was accomplished, pile body itself contact with the soil body and very fits, and often needs the supporting capacity of the stop time competence exertion stake of length itself, and with between be connected relatively poor.
The utility model content
The technical problem that the utility model will solve provides a kind of grouting behind shaft or drift lining concrete pre-stress hollow square pile, to reduce or to avoid problem noted earlier.
For achieving the above object, the technical scheme of the utility model is following:
A kind of grouting behind shaft or drift lining concrete pre-stress hollow square pile; Said grouting behind shaft or drift lining concrete pre-stress hollow square pile y direction, concrete pre-stress hollow square pile center are provided with the central through hole that runs through whole grouting behind shaft or drift lining concrete pre-stress hollow square pile; The cross section of said grouting behind shaft or drift lining concrete pre-stress hollow square pile is that periphery is that the cross section of the central through hole of the square structure of circular arc, said grouting behind shaft or drift lining concrete pre-stress hollow square pile is square, and said grouting behind shaft or drift lining concrete pre-stress hollow square pile is identical in the interior periphery cross section geometry of whole y direction.
Preferably, said grouting behind shaft or drift lining concrete pre-stress hollow square pile length direction is extended with main muscle, Grouting Pipe and the spiral stirrup around said main muscle, and said main muscle is square.
Through technique scheme, the beneficial effect of the utility model is:
A kind of grouting behind shaft or drift lining concrete pre-stress hollow square pile of the utility model, pre-buried Grouting Pipe in the pile body forming process behind pile foundation construction, is carried out grouting process, from but the soil body fully contact with pile body.On the one hand the soil body is fully contacted with pile body, before the soil body stops, higher pile body bearing capacity is provided, simultaneously, slip casting makes the soil body obtain reinforcing, and also can increase pile body bearing capacity, strengthen simultaneously stake with between be connected.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Extremely shown in Figure 3 referring to Fig. 1; A kind of grouting behind shaft or drift lining concrete pre-stress hollow square pile of the utility model; Said grouting behind shaft or drift lining concrete pre-stress hollow square pile y direction, concrete pre-stress hollow square pile center are provided with the central through hole 10 that runs through whole grouting behind shaft or drift lining concrete pre-stress hollow square pile; The cross section of said grouting behind shaft or drift lining concrete pre-stress hollow square pile is that periphery is that the cross section of the central through hole 10 of the square structure of circular arc, said grouting behind shaft or drift lining concrete pre-stress hollow square pile is square, and said grouting behind shaft or drift lining concrete pre-stress hollow square pile is identical in the interior periphery cross section geometry of whole y direction.
The utility model grouting behind shaft or drift lining concrete pre-stress hollow square pile length direction is extended with main muscle, Grouting Pipe 11 and the spiral stirrup around said main muscle, and said main muscle is square.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
