The tubular type anchor rod is simple in structure, convenient for construction and low in cost, can instantly provides anchorage force for controlling the deformation of a rock-soil body, and meanwhile, can improve a load transmission mechanism of rock-soil anchor to improve anchorage force of the anchor rod, so that the stability of the rock-soil body can be significantly improved, and accordingly, the safety of an anchor project can be greatly strengthened.
Description
Technical field
The utility model relates to Anchorage Technology, relates in particular to round pie reinforcement antiskid key 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 theory 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.
Ground anchorage not only is 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.
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, become the raising anchor-holding force of anchor bolt, promote the fundamental way of Anchorage Technology 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 needs after weak rocks soil body excavation provide 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, improves simultaneously the Load Transfer mechanism of ground anchorage to improve the round pie reinforcement antiskid key pipe anchor rod of anchor-holding force of anchor bolt.
For addressing the above problem, round pie reinforcement antiskid key pipe anchor rod described in the utility model, it is characterized in that: it comprises the tubular type body of rod and baffle ring and the backing plate of both ends open, hollow; Be distributed with a plurality of circular blocks on the tube wall of the described tubular type body of rod, its top is filled stemming and is 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 block and be provided with column charge.
Described circular block is made of the closed fanning strip of a plurality of concentrics, and the arc of this closure fanning strip all is on the circumference of described circular block, and is connected with described tube wall; Described closed fanning strip refers to by crossing the described circular block center of circle and penetrating described tube wall radially joint-cutting and the fanning strip that forms.
Described detonator is connected with the detonator payment to a porter.
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 column charge that detonator has been installed is housed.the blast of igniting primer and column charge in one, 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, they are two years old, the detonation of column charge directly strong effect on each closed fanning strip of tubular type body of rod tube wall circular block, closed fanning strip is pushed open, making it be the taper seat shape opens and protrudes from outside tube wall and be pressed into Rock And Soil, namely form the fanning strip that opens, also can provide immediately anchored force, produce anchoring effect, they are three years old, the detonation gas of column charge blast to circular block on drill hole wall to the Rock And Soil of wall impact compress consumingly, cause the circular pit of hole wall Rock And Soil crushing-type, thereupon to filling slurry in tubular type body of rod tube chamber and circular pit, injecting cement paste in circular pit combines with the fanning strip that opens that is deep in circular pit, be cast into round pie reinforcement antiskid key, the tubular type body of rod and Rock And Soil are combined closely, that is by means of the round pie reinforcement antiskid key of embolism between hole wall Rock And Soil and the tubular type body of rod dearly, fundamentally changed the anchoring load pass through mechanism, built friction-reinforcement antiskid key NEW TYPE OF COMPOSITE anchoring, improved significantly the ground anchorage effect, transferred better the self-stable ability of Rock And Soil, effectively prevented anchor rod anchored inefficacy, thereby improved the stability of Rock And Soil, the safety of anchoring 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 ground anchorage effect.
