Description
Technical field
The utility model relates to construction equipment, particularly a kind of tunnel anchor rod component.
Background technology
At present, a kind of mode that engineering adopts in order to the stability improving tunnel surrounding squeezes into anchor pole on country rock, the effects such as the Main Function adopted in such a way is suspention, compound beam, reinforcing arch, except these effects, effect is on the other hand in the STRESS VARIATION of set time monitoring anchor pole under the effects such as country rock extruding, for the rapid construction in tunnel provides safely instruction.
As Fig. 4, in Practical Project, the stressometer of friction anchoring formula anchor rod component is mostly Reinforcement Stress-count.Mainly should be made up of reinforcing bar 1, electronic building brick 3, stressometer 2 and wire 5 etc. with the anchor rod component of Reinforcement Stress-count, wire 5 is drawn from the electronic building brick 3 on stressometer 2 side, and distributes along reinforcing bar 1.
But such anchor rod component existing problems and defect, as workman utilizes air drill to squeeze in the process of anchor rod component in country rock, there is strong rubbing action in Reinforcement Stress-count and country rock, make the wire on stressometer and electronic building brick can be subject to the powerful active force of country rock and damage, such damage is mainly reflected in this stressometer in vibrations process, the exposed wire in reinforcing bar outside with the active force of country rock strong friction power under make wire easily occur crackle in friction process with the disconnection of electronic building brick, electronic building brick is subject to friction and causes sensitivity to decline the even problem such as forfeiture.This interruption just causing anchor stress data to be transmitted, makes the survival rate of anchor rod component greatly reduce, thus correctly can not feed back the information of country rock inside in time, causes negative effect to construction.
Utility model content
For current technology Problems existing, the utility model provide a kind of can the anchor rod component of guardwire and electronic building brick when squeezing into anchor pole.
The technical solution adopted in the utility model is, a kind of tunnel anchor rod component, comprise for the transit joint inserting reinforcing bar in country rock, be arranged at the stressometer on reinforcing bar and be arranged between stressometer and reinforcing bar, this tunnel anchor rod component further comprises electronic building brick, it is characterized in that, described reinforcing bar and/or transit joint are provided with cavity, and described electronic building brick to be arranged in this cavity and to be connected with stressometer, this electronic building brick is by wire transmission of information, and this wire is arranged in described cavity.
When the stress of surrounding rock structure thing changes; reinforcing bar is stretched or compressive strain; this distortion passes to stressometer by transit joint; stressometer also can from extruding variation sensing to STRESS VARIATION; by signal transmission to the electronic building brick be arranged in reinforcing bar cavity; by electronic building brick is arranged in reinforcing bar cavity, the wire serving protection electronic building brick and be connected with this electronic building brick.Electronic building brick is the device that data are passed to wire by stressometer.
Stressometer (stressgauge) is the instrument measuring geostatic stress.The rigidity of the sensor used in the stress measurement of base area is different, sensor can be divided into two kinds: if when the rigidity of ratio of rigidity institute geodetic point rock is large, be called stressometer; If be less than the rigidity of tested regional rock, then claim deformation gauge or strain meter.Here be the stressometer that the rigidity of the ratio of rigidity institute geodetic point rock of the sensor used is large.
Further, described cavity is the deep hole coaxial with reinforcing bar, and the aperture in this hole is arranged on the end face of reinforcing bar one end.
Further, one end of described reinforcing bar is provided with dismountable closing device.
By arranging closing device, to protect the wire be connected with electronic building brick in cavity.
Further, described closing device is nut, and one end of described reinforcing bar is provided with the screw thread for installing nut.
Particularly, gap is provided with between described nut and this end face.
Footpath at the bottom of the internal thread of nut can be set here and be greater than nut aperture, the footpath, top of reinforcing bar threaded one end is greater than the aperture of nut, make this is arranged to the position of threaded reinforcing bar end face in nut and carries out spacing, make nut bottom surface and this end face leave gap, screw thread pair self-locking also can be utilized to leave gap to make nut bottom surface and this end face.(self-locking of screw thread pair energy is because screw thread self-locking, refer to static load and temperature change little time, be threaded and can not automatically get loose.Described screw thread pair energy self-locking is the equivalent friction angle that lead angle is less than screw pair.) allow after nut precession and after leaving space between reinforcing bar end face, electronic building brick and wire can be protected like this, make the acquisition of the accurate safety of data.
Further, described transit joint is frustum cone structure.
Particularly, described stress counts column structure, and these stressometer two ends connect transit joint large end face, and the small end face of this transit joint is connected with the end face of reinforcing bar.
Transit joint is in order to the device between excessive reinforcing bar and stressometer, because stressometer part is relatively thicker in this tunnel anchor rod component, the diameter of reinforcing bar is thinner, and the diameter of reinforcing bar not necessarily, so set up excessive joint according to different bar diameter.
Particularly, described stress counts rectangular structure, and these stressometer two ends connect transit joint large end face, and the small end face of this transit joint is connected with the end face of reinforcing bar.
The beneficial effects of the utility model are:
By arranging cavity in anchor pole; electronic building brick is arranged at the mode in reinforcing bar or in transit joint; make anchor rod component also can protect electronic building brick while use; avoid electronic building brick to contact with country rock with wire, when preventing anchor rod component to squeeze into country rock with anchor pole, active force is to the destruction of electronic building brick and wire.
