Technical field
This utility model relates to underground engineering suspension roof support field, particularly relates to the recognizable loosening country rock of a kind of band self-drilling type
The Bolt System of drill bit.
Background technology
Destroy stress of primary rock poised state after underworkings excavation, thus tunnel-surrounding radial stress can be caused to drop to
Zero, Surrounding Rock Strength is decreased obviously, and stress concentration phenomenon occurs.After this concentrated stress exceedes Surrounding Rock Strength, in tunnel
The crushed zone that peripheral rock is formed is wall rock loosening ring.Its physical state shows as increase and the stress water thereof of Rockmass fractures
Flat reduction.Thus in current Bolt System, just can carry out after generally requiring the scope of the relaxation zone understanding country rock
The design of reasonable supporting parameter.
Wall rock loosening ring is generally of certain shape, when country rock is isotropic, and vertical stress and horizontal stress phase
It is circular Deng then, is otherwise oval；When the non-same sex of country rock, relaxation zone is irregular.Along with roadway excavation is carried out to deep, enclose
Rock mechanical characteristic often shows as nonlinear, and this also has led to the appearance of the various relaxation zone shapes such as butterfly.At anchor pole anchor

Being connected with sender unit, the signal of strain gauge and sound wave signal receiving device collection is sent to by sender unit
Signal receives and processing means.
Above-mentioned band self-drilling type can recognize that in the Bolt System of loosening country rock drill bit, and described acoustic signals receives dress
Putting and be respectively arranged with one in drilling rod both sides, be provided with anti-rattler about, acoustic signals receives device and launches dress by wire with signal
Put connected.
Above-mentioned band self-drilling type can recognize that in the Bolt System of loosening country rock drill bit, described drilling rod is provided with location
Device.
Above-mentioned band self-drilling type can recognize that in the Bolt System of loosening country rock drill bit, and described signal receives and processes
Device includes signal receiving module, signal processing module, memory module, level switch module, display lamp, signal receiving module,
Memory module and level switch module are connected with signal processing module respectively, the output termination display lamp of level switch module.
The beneficial effects of the utility model are: this utility model install additional in Bolt System strain gauge and
Acoustic signals receives device, and stress and the acoustic signals of collection is sent to signal by dispensing device and receives and process dress
Putting, such Bolt System can identify wall rock loosening ring automatically, removes workman from by virtue of experience, according to boring sound and inlet hole
Difficulty determine relaxation zone scope, cause relaxation zone scope sometimes not accurate enough, there is asking of bigger potential safety hazard
Topic.Further, since current relaxation zone shape irregular in the underground engineering of deep, can save a large amount of after automatically identifying relaxation zone
Anchor pole material, reach preferable anchoring effect simultaneously.

Specific implementation method
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model is from left to right followed successively by pdc drill bit 1, band strain gauge pad (stress sensing
Device) 2, drilling rod 3, acoustic signals receive device 4, sender unit 7, localizer 8, adapter 9, anchor pole 10, anchor rod pallet board 11
With clamp nut 12；This utility model outer end has jumbolter 13 offer to creep into power, and the most also signal receives and processes dress
Putting 14, for acoustic signals and the wireless receiving of stress signal, 15 is display lamp.
Described pdc drill bit 1 is threaded connection and is arranged on drilling rod 3, mainly includes composite sheet 17 and wing 18, hydrophthalmia
16, wherein hydrophthalmia 16 is used to carry injecting paste material, such as Fig. 2, shown in 3, wherein pdc drill bit 1 and drilling rod 3 junction have equipped with
The pad 2 of strain gauge, for collecting the stress of pdc drill bit 1 vertical direction, its information sends signal to by wire 6 and sends out
Injection device 7；
As shown in Figure 4, drilling rod 3 receiving device 4 equipped with acoustic signals, described acoustic signals receives device 4 on 3 liang of drilling rod
