Abstract
The utility model discloses a high-resistance constant-resistance compressible anchor cable, which consists of a stranded wire cable body, a tray and a high-resistance constant-resistance compressible anchor device behind the tray. The compressible anchor device adopts a structure with an inner conical locking sleeve and an outer cone-shaped locking tube, and the lock core presents in a structure with cone-shaped appearance and two or more sections of an inner cylindrical tooth; the locking tube presents in a structure with an outer cylindrical surface and an inner cone-shaped surface as well as a limiting device. The high-resistance constant-resistance compressible anchor cable has the advantages that after the wall rock bodies of the laneway are deformed, a large external force effect can be produced, so that when the anchor cable body reaches the pre-determined value before reaching the limit loading point, the compressible anchor device yields to realize the constant-resistance large-size yield under the restriction conditions of sudden increment of resistance and high working anchoring force, thereby realizing the reliability and long residual action of the supporting system, and ensuring the long-time stability, safety and reliability of the laneway project. The high-resistance constant-resistance compressible anchor cable is widely applied to the rock supporting fields such as coal, water conservancy, tunnel and the like.
Description
Technical field
The utility model relates to ground supporting fields such as coal, water conservancy, tunnel, specifically is that a kind of high-drag constant-resistance allows the pressure anchor cable significantly.
Background technology
The anchor shaft anchor cable support technology has occupied leading position with many superiority such as its high workload resistance active supports rapidly in ground supporting field.The distortion coupled wave theory of support material and country rock allows with high workload resistance constraint constant-resistance down presses theory to become to know together.Yet, as everyone knows, in case metal material loading stress in drawing process surpasses its ultimate strength will rupture failure, loses efficacy for avoiding supporting, in existing supporting design and the construction, be to solve by the way that strengthens supporting intensity, obviously this is very uneconomic, and finally still can't fundamentally solve the heavily stressed large deformation problem of deep-well supporting so that maintenance repeatedly, both influence production safety, caused very big waste again.
At present, the method for domestic suitable for surrounding rock large deformation mainly is the employing butterfly pallet, increase the liner that can contract, employing allows pressing spring, cydariform by flexible measures such as pressure rings.Though these methods can increase certain pressure amount that allows, and all have common shortcoming: the one, low-resistance allows pressure, and the rigidity of having lost support system has been sacrificed and has been increased resistive energy, causes the excessive attenuation of country rock self intensity; The 2nd, make the pressure amount little, be not enough to adapt to the large deformation of deep wall rock.Therefore can't fundamentally overcome the disrumpent feelings and supporting failure phenomenon of anchor shaft anchor cable.Being to allow pressure under the low-resistance condition, is very disadvantageous to supporting.
No matter to adopt spring still be cydariform allows pressure by pressure ring, all can not make full use of the stretch-draw section (general 300mm) of anchor cable afterbody, and the anchor cable afterbody that all accounts for after allowing pressing spring or cydariform kill by pressure ring exposes most of stretch-draw section, therefore effectively allows the pressure amount little.
Summary of the invention
The utility model provides a kind of high-drag constant-resistance allow the pressure anchor cable significantly.Be that the constant-resistance that just starts under the high-drag condition allows the pressure anchor cable significantly; allowing wherein pressed ground tackle can just start constant-resistance when reaching the high workload resistance of setting and allowed pressures, thereby reaches decay, protection cable body, the safe and reliable purpose of suitable for surrounding rock large deformation assurance support system of effectively avoiding country rock intensity and self-supporting ability thereof.Overcome the low-resistance that exists in the above-mentioned background technology and allow the drawback of pressing and allow the little deficiency of pressure amount.
This is practical newly realizes with following scheme: a kind of high-drag constant-resistance allows the pressure anchor cable significantly, comprises the steel strand cable body and is positioned at the pallet of steel strand cable body afterbody, is provided with to have the high-drag constant-resistance and allow the ground tackle of compression functions behind the pallet of steel strand cable body afterbody.
The beneficial effects of the utility model are: can adapt to supporting needs under deep-well high-ground stress and the high tectonic stress condition, after the roadway surrounding rock body deforms, powerful external force effect will be produced, during setting value before the anchor cable body reaches capacity disrumpent feelings point, allow and press ground tackle begin to allow pressures, realize that anxious resistance, the high workload anchored force constant-resistance large scale under retraining that increases allows pressure.Thereby reach support system reliability and long-lasting, guarantee well lane engineering long-term stability, safe and reliable purpose.In addition, the utility model makes ground tackle and allows depressor be integrated, and overcome to allow pressing spring and the cydariform also must be in the trouble of anchor tail machining screw by pressure ring etc., and bolt arrangement is difficult to realize the high defective of anchor-hold just.
