Abstract

The invention discloses a quake-proof anchor rope which comprises a free section and an anchoring section, wherein the anchoring section is provided with a quake-proof anchoring device; the quake-proof anchoring device comprises a bearing plate, a quake-proof anchorage device and a permanent anchorage device; a anchor rope passes through the bearing plate and sequentially passes through the quake-proof anchorage device and the permanent anchorage device; the quake-proof anchorage device has a slidable extruding sleeve structure for setting the maximum anchoring force; the quake-proof anchoragedevice is pressed tightly at the inner side of the bearing plate; the permanent anchorage device is a standard extruding sleeve; a certain distance is arranged between the permanent anchorage and thequake-proof anchorage device; when earthquake occurs, huge impact energy is generated instantly so as to lead the stress of the anchor rope to be increased dramatically; in the invention, when the instant impact force born by the anchor rope exceeds the largest static frictional force between the quake-proof anchorage device and the anchor rope, the anchor rope slides relatively to the quake-proof anchor rope, thus buffering the instant impact force of the earthquake; and simultaneously, the absolute length of the free section of the anchor rope is lengthened, thus further reducing the instant impact force born by the anchor rope, preventing the anchoring system from overloading or the rope body from being snapped, and achieving the purpose of quake proof.

Description

Quake-proof anchor rope
Technical field
The present invention relates to a kind of anchorage cable anchoring structure, particularly a kind of quake-proof anchor rope.
Background technology
Because prestress anchorage cable has unique advantage, obtains using comparatively widely in the slope of highway stabilization works.
Prestress anchorage cable is maintaining the security and stability of side slope.The side slope that adopts prestress anchorage cable initiatively to reinforce, general higher steeper, anchor cable is as permanent work and concealed work, and the security and stability of side slope depends on the reinforcement effect of anchor cable to a great extent.
Though prestress anchorage cable has good anchorage effect to side slope, when earthquake takes place,, may cause anchor cable to lose efficacy because the distortion of side slope strenuous vibration produces huge pulling force of moment to anchor cable, threaten the stability and the safety of side slope.
In the anchorage cable anchoring structure, free section has better anti, and still, from whole anchoring system, the anti-seismic performance of prestress anchorage cable is relatively poor, and the inefficacy of various ways takes place when earthquake.As the most frequently used tension type anchor cable, mortar is as the fragile material that almost can not bear pulling force, and under the earthquake motion load action, very easily cracking is also toward the progressive destruction in anchoring section depths.
Therefore, need improve, make it have good anti-seismic performance, guarantee the security and stability of side slope in earthquake and after the earthquake existing side slope prestressed anchor Cable Structure.
Summary of the invention
In view of this, the invention provides a kind of quake-proof anchor rope, have good anti-seismic performance, when earthquake takes place, can avoid anchoring system overload or destruction, reach the purpose of earthquake resistance and prevention.
Quake-proof anchor rope of the present invention, comprise free section and anchoring section, anchoring section is provided with the antidetonation anchor device, the antidetonation anchor device comprises loaded plate, antidetonation ground tackle and permanent ground tackle, anchor cable passes loaded plate and passes the antidetonation ground tackle successively and permanent ground tackle, and the antidetonation ground tackle is for setting the slidably extruded sleeve structure of maximum anchored force, and the antidetonation ground tackle is pressed on the loaded plate inboard, permanent ground tackle is the standard extruded sleeve, between permanent ground tackle and the antidetonation ground tackle determining deviation is set.
Further, the internal circular surfaces of described antidetonation ground tackle is provided with anti-skidding line;
Further, the anti-skidding line of described antidetonation ground tackle is a helicitic texture;
Further, loaded plate arranged outside antidetonation tube, the antidetonation tube is fixedlyed connected with loaded plate;
Further, the loaded plate inboard is provided with protective cover, and described protective cover covers on antidetonation ground tackle and permanent ground tackle outside;
Further, the arranged outside shock-proof check plate of the outer ground tackle of anchor cable, described shock-proof check plate presses outer ground tackle end face.
Beneficial effect of the present invention: when earthquake takes place, with instantaneous generation enormous impact energy, cause the stressed rapid increase of anchor cable, quake-proof anchor rope of the present invention can be when the anchor cable instant impact surpasses maximum static friction force between antidetonation ground tackle and the anchor cable, anchor cable produces with respect to the antidetonation ground tackle and slides, thereby the instant impact of buffering earthquake, simultaneously, the absolute growth of the free section of anchor cable is elongated, further reduce the instant impact of anchor cable, avoid anchoring system overload or cable body to break, reach the purpose of antidetonation, guarantee the security and stability of side slope in earthquake and after the earthquake.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Figure 1A place enlarged drawing;
Fig. 3 is antidetonation ground tackle and anchor cable body matching chart.
The specific embodiment
Fig. 1 is a structural representation of the present invention, Fig. 2 is Figure 1A place enlarged drawing, Fig. 3 is antidetonation ground tackle and anchor cable body matching chart, as shown in the figure: the quake-proof anchor rope of present embodiment, comprise free section 1 and anchoring section 2, anchoring section 2 is provided with the antidetonation anchor device, among the figure, 8 are anchor cable (present embodiment is 4 bundle steel strand), and 9 is Grouting Pipe; Described anchor antidetonation fixing apparatus comprises loaded plate 3, antidetonation ground tackle 4 and permanent ground tackle 5, described anchor cable 8 passes loaded plate 3 and passes antidetonation ground tackle 4 successively and permanent ground tackle 5, antidetonation ground tackle 4 is for setting the slidably extruded sleeve structure of maximum anchored force, 4 pairs of anchor cables of antidetonation ground tackle apply constant radial pressure, thereby contact surface has maximum static friction force; Antidetonation ground tackle 4 is pressed on loaded plate 3 inboards (outside is meant outer ground tackle direction, and the inboard is meant interior ground tackle direction), and permanent ground tackle 5 is the standard extruded sleeve, between permanent ground tackle 5 and the antidetonation ground tackle 4 determining deviation is set.When earthquake takes place when, with instantaneous generation enormous impact energy, cause anchor cable 8 stressed rapid increases, the present invention can be when anchor cable 8 instant impacts surpass maximum static friction force between antidetonation ground tackle 4 and the anchor cable 8, anchor cable 8 produces with respect to antidetonation ground tackle 4 and slides, and makes the absolute growth of anchor cable 8 free sections 1 elongated, thereby reduces the instant impact of anchor cable 8, avoid anchoring system overload or cable body to break, reach the purpose of antidetonation.
In the present embodiment, described antidetonation ground tackle 4 internal circular surfaces are provided with anti-skidding line, are used to control the maximum static friction force of anchor cable 8 and antidetonation ground tackle 4.
