Is not in accordance with the development concept of material saving, energy saving, land saving, water saving and environmental protection, and is not in accordance with the national sustainable development strategy.
At present, recoverable anchor cables mainly have types such as 'U' -shaped detachable recovery type, main working cable type, auxiliary working cable type, hot melting type and the like, although the types of the recoverable anchor cables are more, the recovery effect is not ideal, the recovery equipment is more complex, like a hot melting system for recovering the hot melting type anchor cables, the hot melting system is easy to damage, and the construction operation requirement is higher.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem of the prior art and provide a recoverable anchor rope, in the anchor rope use phase, anchor rope and wedge clamping piece are fastened tightly, expose the end through stretch-draw anchor rope and drive wedge clamping piece and toper sleeve in close contact with, and the anchor rope pulling force is big more, and the anchor is tight more. In the anchor rope recovery stage, the rotary steel strand drives the clamp to rotate towards the direction of the positioning clamping groove in the shell, the positioning guide plate enters the positioning clamping groove to be rotationally fixed, the clamping effect of the wedge-shaped clamping piece on the anchor rope disappears gradually to realize unlocking, and the steel strand can be pulled out easily to realize recovery.
The utility model discloses the technical scheme who realizes as follows, a recoverable anchor rope, draw board, positioning channel section, connector, steel strand wires pipe including casing, toper sleeve, wedge clamping piece, location. The casing passes through threaded connection with the toper sleeve, and the junction is equipped with the sealing washer, and the anchor rope buries underground, infiltrates groundwater, mud etc. easily to make the anchor rope corrosion, influence the removal of anchor rope, set up the sealing washer, can effectively avoid the entering of groundwater, mud etc..
The upper part of the positioning guide plate is provided with two symmetrically-arranged outer square bosses, and the lower part of the positioning guide plate is provided with a circle of continuous outer circular bosses.
The inside positioning groove that is equipped with of casing, the rotatory location draw plate that drives of steel strand wires gets into positioning groove, and the rotatory baffle part that contacts in the positioning groove of the outer square boss of location draw plate, rotatory the end.
The wedge-shaped clamping pieces are 2-3 and are conical after being combined, and anti-skid grains are arranged on the inner sides of the clamping pieces, so that the clamping force on the steel strand is increased. The wedge-shaped clamping piece is provided with a groove on the outer side and fixed by a clamping piece fixing ring, and the wedge-shaped clamping piece is provided with a groove on the inner side and connected with the positioning guide plate through an excircle boss.
The steel strand is sleeved with a hollow sleeve, and the steel strand enters the conical sleeve through the connecting port and is positioned on the same axis with the wedge-shaped clamping piece, the positioning guide plate and the positioning clamping groove.
Compared with the prior art, the utility model have following advantage and effect, structural design is simple reasonable, processing and simple to operate, and the anchorage force is big before retrieving, and convenient and fast during the recovery, workman intensity of labour is little, effectively solves the low, energy-concerving and environment-protective scheduling problem of rate of recovery.

Detailed Description
In order to make the above features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 4, the recoverable anchor cable comprises a shell (1), a conical sleeve (2), a positioning clamping groove (3), a sealing ring (4), a positioning guide plate (5), a wedge-shaped clamping piece (6), a clamping piece fixing ring (7), a connecting port (8), a steel strand (9) and a hollow sleeve (10). Inside steel strand wires (9) passed connector (8) and got into toper sleeve (2), inside steel strand wires (9) outside cover had hollow sleeve (10), threaded connection was passed through with toper sleeve (2) in connector (8), wedge clamping piece (6) are located toper sleeve (2) inside, the surface of wedge clamping piece (6) is identical with the internal surface wedge degree of toper sleeve (2), wedge clamping piece (6) inside is equipped with clamping piece inner groovy (61), clamping piece inner groovy (61) are connected with excircle boss (52) of location draw plate (5), wedge clamping piece (6) outside is equipped with clamping piece outer groove (62), set up clamping piece retainer plate (7) in clamping piece outer groove (62), location draw plate (5), wedge clamping piece (6), clamping piece retainer plate (7) constitute a anchor clamps wholly.
Wherein, casing (1) and taper sleeve (2) pass through threaded connection, and the kneck is provided with sealing washer (4), and the thick liquid infiltration causes the unable condition of retrieving of steel strand wires when avoiding slip casting.
Wherein, 2-3 wedge-shaped clamping pieces (6) are longitudinally arranged and connected together through a clamping piece fixing ring (7). The inner surface of the wedge-shaped clamping piece (6) is provided with anti-skid lines, so that the clamping force between the wedge-shaped clamping piece and the steel strand (9) is increased.
And in the using stage of the anchor cable, one end of the anchor cable with the anchorage device fixed is placed underground, and then grouting is carried out. When the cement paste reaches the strength, the outer part of the other end of the anchor cable is tensioned, the steel strand (9) is fastened with the wedge-shaped clamping piece (6), the exposed end of the tensioned steel strand (9) drives the wedge-shaped clamping piece (6) to be in close contact with the conical sleeve (2), the larger the tension of the anchor cable is, the tighter the anchoring is, and the anchor cable is locked by an external lock until the designed tension value is reached.
In the anchor rope recovery stage, open outside tool to lock, beat steel strand wires (9) front end with the instrument, and carry steel strand wires (9) rotatory certain angle with anchor clamps, steel strand wires (9) drive that the anchor clamps are whole to rotate towards positioning slot (3) direction in casing (1), the department no longer takes place to rotate to baffle (31) of positioning slot (3) after foreign side boss (51) entering positioning slot (3) of location draw plate (5), wedge clamping piece (6) disappear gradually the realization unblock to the clamping effect of steel strand wires (9) this moment, the artifical steel strand wires (9) that can easily pull out realize retrieving.
Although the present invention has been shown and described with respect to the detailed description thereof, it is not intended to limit the present invention, and modifications and variations are possible without departing from the spirit and scope of the present invention as defined in the appended claims.
