Abstract
The utility model relates to a tubular type anchor rod with grouted circular energizing blasting holes for anchoring. The anchor rod comprises a tubular type hollow rod body with two openings formed at two ends, a baffle ring and a backing board, wherein a plurality of circular openings are distributed on the pipe wall of the tubular type rod body in different positions and directions; stemming is filled at the top end of the tubular type rod body, and the baffle ring with the backing board is arranged at the top end; a fulminating charge with a blasting cap is arranged on the pipe wall at the bottom end of the tubular type rod body; and shaped charges are arranged on the pipe walls of the circular openings. The tubular type anchor rod is simple in structure, convenient for construction and low in cost, can instantly provides anchorage force for realizing the effect of instant anchoring; and meanwhile, a conventional anchoring load transmission mechanism is fundamentally changed, so that a novel composite friction-plugging anchoring and pouring reinforced comprehensive support system is established.
Description
Technical field
The utility model relates to rock-reinforcing support technology field, relates in particular to circular CUMULATIVE BLASTING hole slip casting anchoring pipe anchor rod.
Background technology
Ground anchorage is by being embedded in the anchor pole in the stratum, the stratum is locked together tightly, rely on the interaction of anchor pole-injecting cement paste-hole wall ground muscle power, transfer and improve self intensity and self-stable ability of Rock And Soil, improvement by the stress state of anchoring Rock And Soil making it stable, thereby guarantee the technology of engineering safety.The engineering of Anchorage Technology is used and was come from for 19 end of the centurys, development along with its theoretical research and technology, the fields such as mine, water conservancy, water power, highway, railway, municipal administration, urban construction, geology, military project now have been widely used in, as a kind of comparatively desirable support form, play a significant role in underground construction, slope project, deep-foundation pit engineering etc. stable.Slip casting also is called grouting, it is that certain material formulation is become slurries, with force feed equipment, it is poured into and makes its diffusion, gelling or curing in stratum or crack, to reach the purpose of strengthening stratum, slip casting also plays a significant role in Rock And Soil is reinforced, and its application is increasingly extensive.
Ground anchorage and slip casting not only are subject to the impact of formation lithology, Rock-soil Mass Structure, geological structure, hydrogeology etc., also may be subject to the effect of violent earthquake, and they all constitute a threat to the safety of ground anchorage and slip casting.
During the construction and operation of ground anchorage, anchor pole is extracted from injecting cement paste, anchor pole is extracted from anchor hole together with injecting cement paste is two kinds of ground anchorage mode of failure the most basic, and they all can cause ground anchorage to lose efficacy, and bring hidden danger to engineering safety.In order to ensure engineering safety, must limit the anchored force of anchor pole.When the anchored force that provides when needs is larger, the common bolt anchoring can not be satisfied the needs of engineering, this restricts the application and development of Anchorage Technology undoubtedly, how to improve the Load Transfer mechanism of ground anchorage, overcome the drawback of common bolt anchoring, improve anchor-holding force of anchor bolt, the measure of integrated use rock-reinforcing, strengthening the stability of Rock And Soil, is the fundamental way that promotes the rock-reinforcing technical development.
In addition, almost can not provide anchored force before the injecting cement paste in ground anchorage is fixed, therefore can not adapt to the requirement that the rear requirement of weak rocks soil body excavation provides anchored force immediately.Although existing pipe-seam type anchor rod overcomes to some extent to above-mentioned shortcoming, can provide immediately anchored force after rockbolt installation, be conducive in time control the distortion of Rock And Soil, the anchored force that can provide is little; Simultaneously, because soft rock-soil cognition is clamp-oned tube chamber from the pipe seam of pipe-seam type anchor rod, also will cause the further decline of anchored force.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of anchored force that can provide immediately to control the Rock And Soil distortion, improve simultaneously the Load Transfer mechanism of ground anchorage, and Rock And Soil is carried out grouting and reinforcing, to improve the circular CUMULATIVE BLASTING hole slip casting anchoring pipe anchor rod of anchor-holding force of anchor bolt and anchoring effect and Rock And Soil intensity and stability.
For addressing the above problem, circular CUMULATIVE BLASTING described in the utility model hole slip casting anchoring pipe anchor rod is characterized in that: it comprises the tubular type body of rod and baffle ring and the backing plate of both ends open, hollow; A plurality of circular ports that distributing on the tube wall diverse location of the described tubular type body of rod and direction, its top are filled stemming and are provided with described baffle ring with described backing plate; Be provided with the igniting primer that detonator is housed in the tube wall of described tubular type body of rod bottom; Be provided with in the described tube wall of described circular port and be provided with beehive-shaped charge.
Described detonator is connected with the detonator payment to a porter.
Link together by detonating fuse between described beehive-shaped charge, and join with described igniting primer.
Sockets for collecting energy in described beehive-shaped charge be taper shape, hemispherical, semielliptical shape, parabola shaped, hyperbola and tubaeform in a kind of, this sockets for collecting energy is over against described circular port.
Be inlaid with the cavity liner identical shaped with it in described sockets for collecting energy.
The utility model compared with prior art has the following advantages:
1, in the tube wall due to the tubular type body of rod in the utility model, igniting primer and the beehive-shaped charge that detonator has been installed is housed.at first, the blast of igniting primer and beehive-shaped charge in anchor rod body produces strong effect to tube wall, make tubular type body of rod generation plastic strain, cause tube wall radial dilatation extruding Rock And Soil, anchored force can be provided immediately, the relative sliding that stops Rock And Soil and anchor pole reaches the effect of anchoring at once, the particularly important is, the energy-gathering jetting that the beehive-shaped charge blast produces, pressure can reach millions of atmospheric pressure, has very high energies density, directly to the Rock And Soil of the right boring wall of the circular port of tubular type body of rod tube wall impact compress consumingly, the effect of explosive charge to Rock And Soil will be strengthened greatly, cause the hole wall Rock And Soil to be pulverized, the circular CUMULATIVE BLASTING of formation hole in Rock And Soil, by the circular CUMULATIVE BLASTING hole that forms, by tubular type body of rod tube chamber to Rock And Soil slip casting, not only can the grouting and reinforcing Rock And Soil, and the injecting cement paste of filling in tubular type body of rod tube chamber and circular CUMULATIVE BLASTING hole is by the formation anchoring that is connected as a single entity of the circular port on tubular type body of rod tube wall, the tubular type body of rod and Rock And Soil are combined closely, that is by the hole slip casting of circular CUMULATIVE BLASTING, formation to the Rock And Soil grouting and reinforcing time injecting cement paste in circular CUMULATIVE BLASTING hole with tubular type body of rod embolism among boring with its anchoring, fundamentally changed traditional anchoring load pass through mechanism, friction-embolism NEW TYPE OF COMPOSITE anchoring and grouting and reinforcing comprehensive support system have been built, improved significantly the rock-reinforcing effect, transferred better the self-stable ability of Rock And Soil, thereby improved the stability of Rock And Soil, the safety of geotechnical engineering is greatly enhanced.
2, the utility model simple in structure, be convenient to processing, easy construction, with low cost, can speed up the work significantly, improve the rock-reinforcing effect.
