Abstract
The invention relates to an anchor cable anchoring enhancing method and structure. When an anchor cable is installed, an anchoring agent with different condensation speeds is adopted, the condensation speeds of the anchoring agent are sequentially increased from the outer side of a hole to the inner side of the hole, and therefore it is ensured that no condensation can happen to the anchoring agent outside the hole in the anchoring agent stirring and mixing process at different depths, and the anchoring agent is fully stirred and blocked through the anchor cable anchoring enhancing structure. The anchor cable anchoring enhancing structure is composed of a stirring device and a blocking device, wherein a left-hand thread protrusion is arranged outside the stirring device, 2 to 5 stirring teeth are arranged on the top of the stirring device, and a groove matched with one end of the anchoring agent is formed among the stirring teeth so that the anchoring agent can be prevented from deflecting from the center of the drilled hole in the stirring process. The section of the hole in the stirring device of the anchor cable anchoring enhancing structure is conical, and therefore one end of the anchor cable can be conveniently sleeved with the stirring device. The anchor cable anchoring enhancing method and structure have great significance in improving anchor cable anchoring quality and bringing anchor cable breaking force into full play under the special conditions of fault fracture zones, water-bearing roofs and the like, and have good popularization prospects.
Description
Technical field
The invention belongs to support technology field, lane (tunnel) road, relate to specifically be a kind ofly convenient to that anchorage cable anchoring power gives full play to, the anchoring synergisting method that is easy to implement and structure thereof.
Background technology
Along with the complexity of pit mining condition, the Fracture Force of anchor cable is progressively increasing, a lot of mine has employed the anchor cable of diameter 17.8mm, 21.6mm, 28mm at present, this large diameter high Fracture Force cable bolting in guarantee lane (tunnel) road safely, safeguard and play vital effect in lane (tunnel) road surrounding rock stability, but under some special geologic conditions, the such as condition such as fault belt, moisture top board, the anchoring quality of this kind of anchor cable is difficult to ensure, its high supporting intensity advantage is difficult to play.For this kind of problem, mainly take the mode of arranging more Anchor Agents at present, this mode very easily causes the bottom Anchor Agent when top Anchor Agent stirs to produce Hirschfeld-Klinger reaction, to such an extent as to Anchor Agent effect is difficult to make full use of; Simultaneously, because anchor cable surface is comparatively smooth, be difficult to fully, equably stir Anchor Agent, current employing is wound around iron wire, supposes to stir the modes such as circle in end, although certain stirring Anchor Agent effect can be played, but can borehole wall be destroyed unavoidably, cause hole wall disintegrating slag to be doped in Anchor Agent, affect anchoring effect.If a kind of method that can increase anchorage cable anchoring agent effect can be found, and form corresponding, to be convenient to installation anchoring Synergistic structure, the anchoring quality of this high strength anchor cable is promoted significant.
Summary of the invention
Object of the present invention provides a kind of anchorage cable anchoring synergisting method and structure thereof, the stirring that when anchor cable can be made to install, Anchor Agent is full and uniform, and the anchoring effect playing Anchor Agent to greatest extent, to improve the anchoring quality of anchor cable, make full use of anchor cable Fracture Force.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of anchorage cable anchoring synergisting method and structure thereof, when anchor cable is installed, after drilling construction, adopt the Anchor Agent of different setting rate, first Anchor Agent the fastest for setting rate is filled in hole low, then in hole, fill in the slower Anchor Agent of setting rate successively, ensure that Anchor Agent is uniformly mixed process middle and lower part Anchor Agent and can not produces Hirschfeld-Klinger reaction, Anchor Agent stirs the setting time that should be less than Anchor Agent at a slow speed total time, and its anchoring Synergistic structure fully stirs and shutoff Anchor Agent.
A kind of anchorage cable anchoring synergisting method and structure thereof, its anchoring Synergistic structure is provided with the mixing plant of left hand thread projection by outside and plugging device forms, distance between mixing plant and plugging device is anchorage length, its mixing plant top is provided with 2 ~ 5 stirrer gears, be provided with in the middle of multiple stirrer gear one with the groove of Anchor Agent end anastomosis, depart from boring central authorities when preventing Anchor Agent from stirring, stirrer gear can be provided with hole, and Anchor Agent is stirred further.The internal holes section of the mixing plant of its anchoring Synergistic structure is taper, be convenient to mixing plant and be set in anchor cable end, when anchoring Synergistic structure is installed, first plugging device is placed on one end of anchor cable, pressurization between plugging device and anchor cable is made it fastening, then mixing plant is set in anchor cable end, the distance between mixing plant and plugging device is anchorage length.
Beneficial effect of the present invention:
This kind of anchorage cable anchoring synergisting method and structure thereof, Anchor Agent arrangement is for accelerating successively to Anchor Agent setting rate in hole by outside hole, Anchor Agent is uniformly mixed process middle and lower part Anchor Agent can not produce Hirschfeld-Klinger reaction, play the anchoring effect of Anchor Agent to greatest extent, simultaneously, Anchor Agent stirs the setting time that should be less than Anchor Agent at a slow speed total time, avoids the Anchor Agent stirred at first in Anchor Agent whipping process and occurs Hirschfeld-Klinger reaction, cause integral fastening effect to decline.
The mixing plant of its anchoring Synergistic structure can make Anchor Agent fully, equably stir, and the Anchor Agent that plugging device avoids after stirring is dirty, causes Anchor Agent can not well-bonded anchor cable and hole wall.
This kind of anchorage cable anchoring synergisting method and structure thereof, be particularly useful for the anchorage cable anchoring Quality advance under the specific condition such as fault belt, moisture top board, can give full play to the Fracture Force of anchor cable.
