The anchor rope support device can provide reinforced support for a tunnel and ensure the safety of construction; moreover, the cost of the utility model is lower.
Description
Technical field
The utility model relates to a kind of anchor cable support apparatus, relates in particular to a kind of small-bore agitating type anchor cable support apparatus.
Background technology
At present, flourish along with the coal in China cause, the exploitation dynamics in each mining area constantly increases, and the mine roof accident has risen to first of all kinds of accidents.
According to the actual conditions of back inbreak, mining area back mode of failure roughly can reduce following several:
The first, structure destruction because of tunnel false roof, direct top plane of weakness structural development or influenced by structure such as tomography, causes roof collapse;
The second, abscission layer destroy, not enough or the tunnel span is bigger because of the roof timbering resistance, cause and crush, produce absciss layer, and finally cause roof collapse;
Three, influenced by the back production mining pressure, cause the inbreak of top board unstability;
Four, bolt support was lost efficacy, and caused top board to stride.
For this reason, some mining area is shallow in view of its coal seam buried depth, the nearly level in inclination angle, compose and to deposit stable, roof and belong to factors such as stable type and two kinds of top board types of medium stable type, mining conditions be superior more, Shotcrete Rockbolt Support Technique has been actively pushed forward in the mining area aspect supporting, the underworkings supporting has realized that anchor sprayization, particularly coal roadway support have all realized anchor poleization.
Yet along with the continuous expansion and the intensification of mining area exploitation scope, the degree of depth, a series of new situations have appearred in roof control:
The first, indivedual main mining coal seam top board belongs to compound top board, because supporting parameter is improper, can not controls the top effectively and decline, and the face roof accident is in rising trend;
The second, variation of stope bedrock thickness and increasing mining height have certain influence to the stability of top board, and the ore deposit pressure manifests at times strong and at other times weak, and the existing supporting parameter in tunnel has been proposed challenge;
Three, tunneled the influence of technology, the top board condition is not systematically considered in drift section optimization, and some mine only covets drift section can wide then wide, wide then handy effect, because the tunnel is wide and unsettled of crosspoint is bigger, the easy unstability of top board.
At existing problem in the characteristics of mining area roof collapse and the current control, further improve the existing support pattern in mining area, it is imperative to improve supporting quality.Following several scheme is generally being arranged aspect the reinforcement roof control: the one, optimize the section parameter, reduce the tunnel physical dimension; The 2nd, shed shoring; The 3rd, with anchor, net, beam combined supporting form; The 4th, adopt bolt support, and adopt the anchor cable reinforce support.
Wherein, scheme one is subjected to the present driving technology and the restriction of process for stoping, is difficult to realize fully; Scheme two is the incompatibility production technology not only, and its support cost will exceed 2 to 3 times than bolt support.And scheme three is compared with scheme four, and scheme four can strengthen anchorage depth, more reliable technically, safety; See that economically the cost of scheme four is lower.
Therefore, be necessary to design a kind of anchor cable support apparatus that is used for reinforce support, to overcome above-mentioned defective.
The utility model content
The purpose of this utility model is to provide a kind of anchor cable support apparatus, by using this anchor cable support apparatus, can be the tunnel reinforce support is provided, and ensure construction safety, and its cost is lower.
In order to realize the foregoing invention purpose, the utility model is design like this: this anchor cable support apparatus comprise outer ground tackle, with the pallet of the adjacent setting of outer ground tackle, through the anchor cable of outer ground tackle and pallet, with outside the strand that is oppositely arranged of ground tackle accompany block, anchoring agent and be located at anchor cable and the baffle ring of anchoring agent junction.
By using this anchor cable support apparatus, can be the tunnel reinforce support is provided, ensure construction safety, and its cost is lower.
Description of drawings
Below, will be described in further detail the specific embodiment of the present utility model in conjunction with the accompanying drawings, wherein:
Fig. 1 is the sectional view of anchor cable support apparatus of the present utility model.
The specific embodiment
See also Fig. 1, anchor cable support apparatus 1 of the present utility model is used to the reinforce support in the mine laneway.
Anchor cable support apparatus 1 comprises outer ground tackle 10, the supporting plate 20 adjacent with outer ground tackle 10, pass the anchor cable 30 of outer ground tackle 10 and supporting plate 20, be arranged at outer ground tackle 10 relative ends baffle ring 40, stir card 50 and anchoring agent 60.
Wherein, outer ground tackle 10 adopts its wedge structures, can wedging anchor cable 30, and make anchor cable 30 stressed.The specification of described supporting plate 20 can adopt two kinds: a kind of is 300 * 300 * 15mm, uses separately; Another is 100 * 90 * 10mm, need use jointly with combined members such as steel bands.
The cable body of anchor cable 30 adopts the anchor twisted wire that can adopt high strength, underrelaxation, and described anchoring Ji 60 is a resin explosive roll, and this resin explosive roll comprises quick powder stick and middling speed powder stick two parts, and common one need 2 to 3 anchoring agent with anchor cable 30.
After this anchor cable support apparatus 1 installs, anchor cable 30 is delivered to the top board deep with top board self pressure and stablizes in the rock stratum, under anchor cable 30 prestressed effects, the rock stratum in its anchoring scope is compressed, and makes unconsolidated formation and plane of weakness form " bridle " under its elastic compression.
This anchor cable support apparatus 1 is as reinforce support, i.e. anchor cable support apparatus 1 and bolt support coupling.When in the tunnel bolt support being arranged, before playing anchor cable 30, formed " pressing beam ", add anchor cable 30 on this basis, the corresponding thickness of thickening beam has played that the next " pressing beam " is fixed to suspention effect under the stable rock stratum, deep.Thereby, can control surrouding rock deformation effectively, improved country rock intensity and globality.
By using this anchor cable support apparatus 1 to compare with the common bolt supporting, the one, its length is bigger, can anchor into the deep and stablize in the rock stratum; The 2nd, can apply prestressing force, restriction rock mass deformation development keeps the stable of rock mass.Therefore, can be the tunnel reinforce support is provided, ensure construction safety, and its cost is lower.
