Description
Technical field:
The invention belongs to building operations uplift pile technical field, relate to a kind of anti-floating stake of miniature anti-floating stake, particularly a kind of built-in nonmetal muscle material.
Background technology:
Along with the development and use of urban underground space, the embedded depth of foundation of building constantly increases, and the anti-floating problem becomes more and more outstanding, and present anti-floating technology mainly contains anti-floating technical measures such as falling row's underground water, ballast method, the stake of major diameter anti-floating; Wherein the anti-floating stake is used comparatively extensive, but there are many problems in the anti-floating stake in the reality, the anti-corrosion protection of anti-floating stake for example, anti-floating stake anti-corrosion measure commonly used at present mainly contains: adopt corrosion inhibitor, epoxy coating reinforcing bar, strengthen protective layer thickness, rebar surface preservative treatment and cathodic protection etc.; But muscle material surface anticorrosive is handled and the safeguard measure of isolating and insulating is all adopted in cathodic protection, the material that adopts or bigger to the influence of reinforced steel bar strength and adhesion stress, or cost is higher, aseptic technic does not also obtain the breakthrough of essence, in urban traffics such as subway are built, by the stray electrical current that DC power-supply system produces, the electrochemical corrosion that metal material is produced more can not fundamentally solve; With respect to common anti-floating stake, it is strong that miniature anti-floating stake has a ground adaptability, advantages such as arrangement form is flexible, pore-forming is fast, little, the construction machinery miniaturization of construction occupied ground and economic environmental protection, particularly bearing capacity is big in the hard rock soil layer, it has more advantage, to become the measure of anti float of preferential employing gradually; Its operating principle is for burying miniature anti-floating stake underground in the stratum, utilize miniature anti-floating stake pulling force and miniature anti-floating stake integrated mortar (pea gravel concreten) anchoring body and with stratum consolidation, so that the stratum forms the globality structure, make the frictional force of miniature anti-floating stake greater than hydraulic pressure buoyancy, play the effect of anti-floating, thereby reach the purpose of its distortion of control; But at present the pile body muscle material of the miniature anti-floating stake of using adopts metal material mostly, treat that it imbeds the rock mass soil layer after, along with the continuity of time, often contain Na in the underground water
+, Ga
2+, Mg
2+, Cl-, SO
4 2-Plasma panel makes material of body of a pile suffer chemical attack easily, influence miniature anti-floating strength of the mixing pile, and then its anchoring effect damaged, this phenomenon is particularly outstanding aspect the anti-floating on building basis, coastal area, in Construction of Urban Rail Traffic such as subway, stray electrical current by DC power-supply system produces produces electrochemical corrosion to metal material and exists too in miniature anti-floating stake, and the anticorrosion problem of miniature anti-floating stake in the stratum also is present problem demanding prompt solution.
Summary of the invention:
The objective of the invention is to overcome the defective that exists in the prior art, seek to design and a kind ofly can effectively solve miniature anti-floating stake and suffer the measure of etching problem, under the prerequisite that does not raise the cost, provide a kind of corrosion resistance good, anti-pulling capacity height, the anti-floating stake that can improve the built-in nonmetal muscle material in application life.
To achieve these goals, agent structure of the present invention comprises interior anchoring section, outer anchoring section, miniature pile body, muscle body separator, steel sleeve, rigidity stress diffusion disc, muscle body and concrete floor; Wherein miniature pile body is built-in with muscle material or the muscle body of full thread solid construction, the material of muscle body is glass fiber reinforced polymer (GFRP), the separator of muscle body is annulus four horn shapes, the circular hole that evenly distributes and communicate with the muscle body on its annulus, the internal diameter of steel sleeve is greater than the diameter of muscle body, rigidity stress diffusion disc is square, the circular hole that evenly distributes and communicate with steel sleeve on the rigidity stress diffusion disc; Whole anti-floating stake is made up of interior anchoring section and outer anchoring section two parts, and the interior anchoring section of miniature anti-floating stake (the being miniature pile body) outside is connected with miniature pile body, and the centering when playing miniature anti-floating stake installation acts on; Miniature pile body is built-in with some nonmetal muscle bodies, and muscle body separator is sleeved on equally spacedly on the muscle body and with inwall and the muscle material of miniature pile body and is connected, and plays the fixedly effect of muscle body centering; Steel sleeve is sleeved on the muscle body of outer anchoring section, and certain spacing is left on the top of steel sleeve and miniature pile body, and the packing ring epoxy resins closely links together it between steel sleeve inboard and the muscle body; Rigidity stress diffusion disc is inserted on the steel sleeve by through hole, by the mode of welding rigidity stress diffusion disc is connected with steel sleeve.
When the present invention realizes installing, hole in Rock soil Foundation according to size and the position of miniature pile body, to form miniature anti-floating stake hole, stake hole and ground are perpendicular; The miniature pile body that muscle body separator is installed is inserted in the stake hole, manually send into, arrive bottom, stake hole until miniature pile body bottom, keep the vertical of miniature pile body in the installation process; The outer end in mini pile hole connects Grouting Pipe, Grouting Pipe is extended a bottom, hole, with grouting pump slurries are injected along Grouting Pipe, when treating that injection slurry arrives the injected hole top Grouting Pipe extracted and close grouting pump, so far finish whole slip casting process, after slip casting is finished that the injected hole top is manually floating; Muscle body at the outer anchoring section of miniature pile body is installed steel sleeve, and steel sleeve is by epoxy resin and muscle body tight bond, and the length of steel sleeve determines according to the design anchored force; With welding manner rigidity stress diffusion disc is installed in the steel sleeve outside, the installation site of rigidity stress diffusion disc is control criterion with the thickness of concrete foundation base plate, and rigidity stress diffusion disc floor space size and empty quantity determine according to the design anchored force; According to the outer anchoring section length that miniature pile body is determined in thickness and the anti-floating requirement of concrete floor, so far finish the installation process of whole miniature anti-floating stake.
The present invention compared with prior art, the muscle body of miniature anti-floating stake and muscle material have adopted glass fiber reinforced polymer (GFRP), can effectively avoid the anti-floating stake to be corroded, and prolong the application life of anti-floating stake, outer anchoring section is equipped with steel sleeve and stress diffusion disc simultaneously, improve the anchored force of anti-floating stake, its technology is simple, and installation is convenient, cost is low, the reliability height, good in economic efficiency, have outstanding substantive distinguishing features and obvious improvement.
