Description
Technical field
The utility model relates to all construction project fields such as building, municipal administration, traffic, water conservancy, electric power, industry, particularly relates to a kind of recyclable steel strand abnormity soldier pile based on prestressing technique.
Background technology
Base pit engineering technical scheme is mainly considered from aspects such as security reliability, economic rationality, difficulty of construction, construction periods.Prestressed reinforced concrete stake is widely used in present base pit engineering.Prestressed concrete refers to cracking resistance in order to improve reinforced concrete member and avoids reinforced concrete member to occur crack too early, and in concrete component prefabrication process by presstressed reinforcing steel to its in advance stress application to improve a kind of method of component performance.Prestress wire in existing prestressed concrete pile can not reclaim after pile body completes main purpose or recovery difficult larger.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of recyclable steel strand abnormity soldier pile based on prestressing technique, simple and reasonable, after pile body completes main purpose, discharge stretching end prestressing force, steel strand can be pulled out easily by mechanical force, reach the object of recovery.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of recyclable steel strand abnormity soldier pile based on prestressing technique, comprise: concrete pile body, described concrete pile body inside has at least one built-in pipe, described built-in pipe is U-shaped, the bottom fold place of described built-in pipe is positioned at bottom concrete pile body, and two ends of described built-in pipe pass the top of concrete pile body, are equipped with U-shaped prestress wire in described built-in pipe.
In the utility model preferred embodiment, be closed pyramid-shaped structures or conical structure bottom described concrete pile body.
In the utility model preferred embodiment, described concrete pile body inside has a hollow round hole, and described hollow round hole extends along the length direction of concrete pile body, extends upwardly to concrete pile body top and forms opening, extend downward bottom concrete pile body, but do not pass concrete pile body.
In the utility model preferred embodiment, the cross section outline of described concrete pile body comprises two straight flanges be parallel to each other and is positioned at two arc-shaped edges at straight flange two ends.
In the utility model preferred embodiment, the inside of described concrete pile body also has many arrangements of reinforcement.
In the utility model preferred embodiment, described built-in pipe is PE pipe, and the inner surface of described built-in pipe has polytetrafluorethylecoatings coatings.
The beneficial effects of the utility model are: the utility model is based on the recyclable steel strand abnormity soldier pile of prestressing technique, simple and reasonable, after pile body completes main purpose, discharge stretching end prestressing force, steel strand can be pulled out easily by mechanical force, reach the object of recovery.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model based on recyclable steel strand abnormity soldier pile one preferred embodiment of prestressing technique;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
In accompanying drawing, the mark of each parts is as follows: 1, concrete pile body, and 11, straight flange, 12, arc-shaped edges, 2, built-in pipe, 3, U-shaped prestress wire, 4, hollow round hole.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of recyclable steel strand abnormity soldier pile based on prestressing technique, comprise: concrete pile body 1, the inside of described concrete pile body 1 also has many arrangement of reinforcement (not shown)s, be the pyramid-shaped structures closed or conical structure bottom described concrete pile body 1, pile body can be reduced and press down soil body resistance in process.
Described concrete pile body 1 inside has at least one built-in pipe 2, as shown in Figure 2, preferred four built-in pipes in the present embodiment, described built-in pipe 2 is in U-shaped, the bottom fold place of described built-in pipe 2 is positioned at bottom concrete pile body 1, two ends of described built-in pipe 2 pass the top of concrete pile body 1, U-shaped prestress wire 3 is equipped in described built-in pipe 2, the bottom natural of described U-shaped steel strand 3 forms an anchored end, two ends of described U-shaped prestress wire 3 pass from two of built-in pipe 2 ends respectively, form stretching end, before pile body bears external load, at stretching end, stretch-draw is carried out to steel strand, apply compressive pre-stress, improve bending resistance and the rigidity of pile body, postpone the time that crack occurs, increase the durability of pile body, after pile body completes main purpose, discharge stretching end prestressing force, pull out steel strand by mechanical force, reach the object of recovery.
Preferably, described concrete pile body 1 inside has a hollow round hole 4, described hollow round hole 4 extends along the length direction of concrete pile body 1, opening is formed at concrete pile body 1 top, described hollow round hole extends downward bottom concrete pile body 1, but does not run through concrete pile body, and the advantage of this hollow round hole 4 to save material, give full play to circular arch effect, reduce resistance at pile body pressing down in process.
The cross section outline of described concrete pile body comprises two straight flanges be parallel to each other 11 and is positioned at two arc-shaped edges 12 at straight flange 11 two ends, forms odd-shaped cross section, mainly by circular arch as appropriate force transmission mechanism.
Described built-in pipe 2 is PE pipe, the inner surface of described built-in pipe 2 has polytetrafluorethylecoatings coatings, the surperficial smoother of polytetrafluorethylecoatings coatings, like this after pile body completes main purpose, during pull-out steel strand, more laborsaving.
The beneficial effects of the utility model are: the utility model is based on the recyclable steel strand abnormity soldier pile of prestressing technique, simple and reasonable, after pile body completes main purpose, discharge stretching end prestressing force, steel strand can be pulled out easily by mechanical force, reach the object of recovery.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
