Detailed description of the invention
Describe the technical solution of the utility model in detail below with reference to drawings and the specific embodiments, so as clearer, understand utility model essence of the present utility model intuitively.
As shown in Figures 1 and 2, and in conjunction with Fig. 3, one provided by the utility model reclaims prestressed anchor entirely, is mainly used in building foundation pit construction and uses.
Specifically, one provided by the utility model reclaims prestressed anchor entirely, comprises upper end and lower end, and described upper end is free segment 10, in order to be connected with prop 100 with building operations; Described lower end is anchoring section 20, improvement of the present utility model is, described anchoring section 20 is for adopting the cold solid material of thermoplastic to pour into a mould the hollow circular cylinder forming, the center adaptation of described hollow circular cylinder has a central tube 30 that extends to described free segment 10, is fixed with a heating wire 40 in described anchoring section 20 around described central tube 30; In described hollow circular cylinder, be evenly equipped with the many steel strand 50 that extend to described free segment 10 along its circumferencial direction, in the present embodiment, described top and bottom are by the elongated setting of steel strand, just lower end is to be cast with in the appearance of described steel strand the hollow circular cylinder that adopts the cold solid material of thermoplastic to make, and wherein described in two, steel strand 50 are connected with the two-stage of described heating wire 40 by a heating wire wiring terminal 60 near one end of anchoring section, other end external power supply 70.
It should be noted that, in the present embodiment, the cold solid material of described thermoplastic is sulphide mastic, and described central tube 30 is heat proof material, it can be heating resisting metal material or heatproof nonmetal material, the external surface of central tube 30 also wraps up or is coated with one deck insulation materials, and to make in the time utilizing the utility model to carry out operation, central tube is non-conductive.
For ease of more thorough understanding implementation step of the present utility model, elaborate below with reference to Fig. 1, Fig. 2 and Fig. 3.
Concrete construction method of the present utility model, comprises the following steps:
S1, digged pit in construction ground 80, to form foundation ditch 90, construction supporting piling wall or supporting aspect, build pattern foundation pit supporting structure body 100 sidewalls.
S2, prefabricated prestressed anchor as claimed in claim 1;
S3, hole to underground in the inner side of described foundation pit side-wall, to form bolthole, the anchoring section of described prestressed anchor 20 is transferred in described bolthole;
S4, in described bolthole, in the interior injected water mud of described central tube 30, after the cement paste initial set of central tube 30 interior injections, secondary grouting is carried out in the gap between described hollow circular cylinder and bolthole, so that described anchoring section 20 glueds joint and forms anchoring body with underground ground;
S5, on described prop 100, certain position arranges anchor pole base, solidify and meet the requirements of after intensity until described anchoring body, the free segment of described prestressed anchor 10 is fixed on described anchor pole base, so that prestressed anchor and described prop 100 are strained, prestressed anchor enters duty;
S6, foundation ditch 90 have been constructed, and along with underground structure rises, prestressed anchor work completes, and removes the anchor pole base on prop 100, makes many described steel strand 50 in free state;
S7, adopt the fixture of two tape insulation handles to connect respectively wherein two steel strand 50 that connected power supply 70, switch on power 70, so that steel strand 50, power supply 70, heating wire 40 form loop, heating wire 40 heating of switching on, adopt the cold admittedly anchoring section 20 that material is poured into a mould the hollow circuit cylinder body structure forming of thermoplastic because of heating wire 40 heating deliquescing, steel strand 50 get loose;
S8, first choose and do not connect the steel strand 50 of power supply 70 by external force, then 70 the steel strand 50 of switching on power of choosing, steel strand 50 are removed complete, and the described heating wire 40 being connected with steel strand 50 also can be chosen accordingly, and prestressed anchor reclaims complete entirely.
It should be noted that, described central tube 30 also can adopt center bar, in the time that described central tube 30 adopts center bar, need to bind a Grouting Pipe at the sidewall of described anchoring section 20, now, available this Grouting Pipe replaces central tube 30, implements the slip casting operation to anchoring section 20, at this, do not elaborate.
By this, in the utility model embodiment, described anchoring section 20 is except steel strand 50, only containing a small amount of metal material, and do not need extra wire, switch on power 70, by the heating of heating wire 40, anchoring body is subject to after thermal softening, steel strand 50 separate with anchoring body is easy, and then the steel strand of anchoring section 20 50 can be taken out, and reach the object of substantially removing the metal material being buried in the earth completely, make effectively to remove metal garbage in soil, effectively reduce the environment pollution that metal garbage causes.
And the utility model is simple in structure, cost is low, and the required manpower of metal recovery is few and reclaim totally, convenient and swift, has larger environment protection significance and higher application value, can be very welcome, can be used widely.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; everyly utilize equivalent structure that manual of the present utility model and accompanying drawing content do or the conversion of equivalent flow process; or be directly or indirectly used in other relevant technical fields, within being all in like manner included in scope of patent protection of the present utility model.
