Description
Technical field
The present invention relates to field of civil engineering, more particularly to a kind of anti-lateral deflection anti-float anchor rod of retardation setting type and its construction method.
Background technology
Anti-float anchor rod is a kind of conventional structural elements for providing underground structure, underground structure anti-floating ability.Its
The body of rod is made by reinforcing bar, steel strand wires, steel pipe etc., and most of to be implanted into foundation soil, upper end is anchored into basis.Work as hypogee
When thing, structures are by upward water buoyancy, anti-float anchor rod will constrain building, structures, prevent its floating.
In construction period due to using precipitation means, basement and the effect for being not affected by upward water buoyancy；As top is built
The progressively construction of thing is built, downward pressure incrementally increases, and basis is inevitable to produce downwards certain sedimentation.And the anti-float anchor rod body of rod is
Elongated metallic member, larger anti-pulling capacity can be produced but pressure can not be born, therefore with setting of ground, anchor rod body
Inevitable compressive buckling.
When construction is completed, precipitation terminates, and when basement starts to bear upward water buoyancy, is stretched in the anti-float anchor rod of lateral deflection
After be only possible to basement provide constraint.So not only anti-float anchor rod is poor to basement anti-floating binding effect, and anti-floating anchor
Under pressure is drawn repeatedly, intensity can also decline club shaft.
Therefore, it is necessary to prior art is improved.
The content of the invention
It is an object of the invention to provide a kind of anti-lateral deflection anti-float anchor rod of retardation setting type and its construction method, construction period is prevented
Anti-float anchor rod compressive buckling, and then weaken anti-floating binding effect and lever strength.
To achieve the above object, the present invention uses following technical scheme：

In basis, the inner hollow of metal tube and retarding mortar is perfused with, the upper end closed and lower ending opening of metal tube；The body of rod
Bottom implantation foundation soil in, the top of the body of rod is through cock body and stretches into metal tube；The cock body is arranged at metal tube lower end
Opening, metal tube lower ending opening is blocked and is relatively fixed metal tube and the body of rod；The upper end of the body of rod and the upper end of metal tube
An intersegmental gap is left between inwall.
Further, the metal tube is metal bellows.
Further, the cock body is in round table-like rubber stopper, and the middle part of rubber stopper is provided with the through hole passed through for the body of rod.
Further, the upper end of the metal tube is provided with aspirating hole.
The construction method of the anti-lateral deflection anti-float anchor rod of retardation setting type described in more than one, including：
S1, metal tube is inverted, retarding mortar is injected in metal tube；
S2, cock body is enclosed on the body of rod, and body of rod top is inserted in metal tube；
S3, after using cock body, metal tube lower ending opening is blocked, metal tube is together just being put with the body of rod；
S4, treat that retarding mortar flow to metal tube bottom, gap is formed on metal tube top；
S5, it is implanted into foundation soil internal drilling and by the bottom of the body of rod, then is cased with pouring at metal tube on body of rod top and smashes construction
Basis.
Further, the S4 also includes：Extract the air in gap out.
The present invention utilizes the characteristic of retarding mortar, by above-mentioned construction, as upper load increases base in work progress
Plinth starts to settle, and during retarding mortar ot-yet-hardened, the body of rod can the free movement in metal tube, ensure the body of rod not by lateral deflection；Treat
Construction finishes, and after foundation settlement is stable, retarding mortar solidification, the body of rod plays anti-floating effect.
Compared with prior art, the anti-lateral deflection anti-float anchor rod of retardation setting type provided by the present invention has preferably anti-to basement
Floating binding effect, it also ensure that lever strength does not reduce because pressing drawing repeatedly.

Embodiment
Technical scheme is described in detail below in conjunction with accompanying drawing and specific embodiment.
As depicted in figs. 1 and 2, anti-floating binding effect and the body of rod are weakened to solve construction period anti-float anchor rod compressive buckling
The problem of intensity, the invention provides a kind of anti-lateral deflection anti-float anchor rod of retardation setting type.Specifically, it includes the body of rod 1, metal tube 2, delayed
Solidifying mortar 3, cock body 4；The metal tube 2 is anchored in basis 5, the inner hollow of metal tube 2 and is perfused with retarding mortar 3, gold
Belong to the upper end closed and lower ending opening of pipe 2；In the bottom implantation foundation soil 6 of the body of rod 1, the top of the body of rod 1 passes through cock body 4 simultaneously
Stretch into metal tube 2；The cock body 4 is arranged at the lower ending opening of metal tube 2, the lower ending opening of metal tube 2 is blocked and by metal
Pipe 2 and the body of rod 1 are relatively fixed；An intersegmental gap 10 is left between the upper end of the body of rod 1 and the upper end inwall of metal tube 2.
Retarding mortar 3 be by cement, compound retarder and sand through suitably matching the extraordinary mortar formed, can one compared with
Do not solidified in the long period, and can reach higher-strength after solidifying, it is more at present to be applied in advance as grouting material
In power concrete works.
By above-mentioned construction, as upper load increases in work progress, when basis 5 starts sedimentation, retarding mortar 3 is not yet
Solidification, the body of rod 1 can the free movement in metal tube 2, ensure the body of rod 1 not by lateral deflection.It is to be onstructed to finish, after basic 5 settlement stabilities,
Retarding mortar 3 solidifies, and the body of rod 1 plays anti-floating effect.
Further, as shown in figure 3, in the embodiment of the present invention, the metal tube 2 preferably uses metal bellows, ripple
It can strengthen and be engaged ability between metal tube 2 and retarding mortar 3 and basis 5.
Further, as shown in figure 4, the cock body 4 is in round table-like rubber stopper, the middle part of rubber stopper, which is provided with, supplies the body of rod
1 through hole 41 passed through.The main function of cock body 4 is to prevent that retarding mortar 3 from leaking down and the motion to the body of rod 1 play the guiding role, plug
The compressibility of the above-mentioned shape cooperation rubber of body 4, when basis 5 sinks, cock body 4 is progressively squeezed into metal tube 2, with reduction pair
Hindered caused by the free movement of the body of rod 1.
Further, as shown in figure 3, the upper end of the metal tube 2 is provided with aspirating hole 20.Provided in an embodiment of the present invention
After the anti-lateral deflection anti-float anchor rod of retardation setting type is completed, the air in gap 10 can be extracted by aspirating hole 20, to reduce the portion
Dividing air compression, the free movement to the body of rod 1 produces obstruction afterwards to a certain extent.
The embodiment of the present invention additionally provides the construction method of the anti-lateral deflection anti-float anchor rod of retardation setting type described in more than one, specifically
Ground, the construction method include：
S1, metal tube 2 is inverted, retarding mortar 3 is injected in metal tube 2；
