Description
Technical field
The present invention relates to rock-reinforcing support technology field, particularly relate to linear cavity energy explosion slip casting anchoring pipe anchor rod.
Background technology
Ground anchorage is the anchor pole by burying underground in the earth formation, stratum is locked together tightly, rely on the interaction of anchor pole-injecting cement paste-hole wall ground muscle power, transfer and improve self-strength and the self-stable ability of Rock And Soil, improve by the stress state of anchoring Rock And Soil to make it stable, thus guarantee the technology of engineering safety.The engineer applied of Anchorage Technology came from for 19 end of the centurys, along with the development of its theoretical research and technology, now the fields such as mine, water conservancy, water power, highway, railway, municipal administration, urban construction, geology, military project are widely used in, as a kind of ideal support form, underground construction, slope project, deep-foundation pit engineering etc. stable in play a significant role.Slip casting is also called grouting, it is that certain material formulation is become slurries, poured in stratum or crack with force feed equipment make it spread, gelling or solidification, also can reach the object of strengthening stratum, reinforce one of important measures as at Rock And Soil, its application is increasingly extensive.
Ground anchorage and slip casting are not only subject to the impact of formation lithology, Rock-soil Mass Structure, geological structure, hydrogeology etc., and also may be subject to the effect of violent earthquake, 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, the anchored force of anchor pole must be limited.When the anchored force needing to provide is larger, common bolt anchoring can not meet the needs of engineering, this restricts the application and development of Anchorage Technology undoubtedly, how to improve the loading 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 promoting rock-reinforcing technical development.
In addition, before the injecting cement paste consolidation in ground anchorage, almost can not provide anchored force, therefore after weak rocks soil excavation can not be adapted to, require the requirement that anchored force is provided immediately.Although existing pipe-seam type anchor rod overcomes to some extent to above-mentioned shortcoming, can provide anchored force immediately after rockbolt installation, be conducive to the distortion controlling Rock And Soil in time, the anchored force that can provide is little; Meanwhile, know from experience due to soft rock-soil and clamp-on 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 by this invention is to provide one can provide anchored force to control Rock And Soil distortion immediately, improve the loading transfer mechanism of ground anchorage simultaneously, and grouting and reinforcing is carried out to Rock And Soil, to improve anchor-holding force of anchor bolt and to improve anchoring effect and strengthen the linear cavity energy explosion slip casting anchoring pipe anchor rod of Rock And Soil intensity, stability.
For solving the problem, linear cavity energy explosion slip casting anchoring pipe anchor rod of the present invention, is characterized in that: it comprises both ends open, the tubular type body of rod of hollow and baffle ring and backing plate; The diverse location of described tubular type body of rod tube wall and direction are dispersed with multiple rectangular cutout, and its top is filled stemming and is provided with the described baffle ring of the described backing plate of band; The igniting primer that detonator is housed is provided with in the tube wall of described tubular type body of rod bottom; Layout of linear shaped charge is provided with in the described tube wall being provided with described rectangular cutout.
Described detonator is connected with detonator payment to a porter.
Sockets for collecting energy in described layout of linear shaped charge is linear, and this sockets for collecting energy is just to described rectangular cutout.
The linear cavity liner with its same shape is inlaid with in described sockets for collecting energy.
The present invention compared with prior art has the following advantages:
1, because the tube wall of the tubular type body of rod in the present invention is built with the igniting primer installing detonator and layout of linear shaped charge.First, the blast of igniting primer and layout of linear 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 to extrude Rock And Soil, anchored force can be provided immediately, stop the relative sliding of Rock And Soil and anchor pole, reach the effect of anchoring at once, the particularly important is, layout of linear shaped charge explodes the energy-gathering jetting produced, there is high pressure, speed and energy density, directly to the Rock And Soil impact compress consumingly of the right boring wall of the rectangular cutout of tubular type body of rod tube wall, the effect of explosive charge to Rock And Soil is greatly enhanced by layout of linear shaped charge, hole wall Rock And Soil is caused to be pulverized, linear cavity energy Cut blasting seam is formed in Rock And Soil, by the linear cavity energy Cut blasting seam formed, by tubular type body of rod tube chamber to Rock And Soil slip casting, not only can grouting and reinforcing Rock And Soil, and the injecting cement paste be filled in tubular type body of rod tube chamber and linear cavity energy Cut blasting seam to be connected as a single entity formation anchoring by the rectangular cutout 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 slip casting of linear cavity energy Cut blasting seam, form and among boring, anchoring is made it tubular type body of rod embolism to the injecting cement paste in cumulative charge seam linear while Rock And Soil grouting and reinforcing, fundamentally change traditional anchoring load pass through mechanism, construct friction-embolism compound anchoring and grouting and reinforcing comprehensive support system, significantly improve rock-reinforcing effect, transfer the self-stable ability of Rock And Soil better, thus improve the stability of Rock And Soil, the safety of geotechnical engineering is greatly enhanced.
2, structure of the present invention simple, be convenient to processing, easy construction, with low cost, can speed up the work significantly, improve rock-reinforcing effect.
