Condition is typically only possible by into tunnel is observed, in-site measurement obtains, and this just needs technical staff and each side supervisor frequency
It is numerous to enter tunnel.And in major long tunnel, personnel are long the time required to commuting, at the same personnel's vehicle can also increase in tunnel it is logical
Wind demand, commuting cost are high.
With the development of remote control technology in tunnel, and for the consideration to cost of labor and personal security, rely on
Traditional manual measurement method can not be well adapted for the requirement constructed at present, therefore be highly desirable to invent a kind of tunnel
The automatic acquiring method of road digging footage, to coordinate other remote monitoring measures to be used in conjunction with being supervised outside tunnel to reach
The purpose of control.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art, there is provided a kind of tunnel piercing drilling depth automated watch-keeping facility and
Method.
A kind of tunnel piercing drilling depth automated watch-keeping facility, including the first shock-wave detection instrument, the second shock-wave detection instrument and

4) repeatedly measurement construction trolley obtains average distance S to the distance between face2；
5) by the distance S of the construction trolley being calculated to hole1And manual measurement construction trolley is between face
Average distance S2It is added, the as distance L at hole to face；
L=S1+S2。
Described method, shock-wave detection instrument should be arranged at abutment wall, and two shock-wave detection instrument are installed in same
Highly, so as to calculate shock wave for the first time reach correct time difference Δ t.
Described method, shock-wave detection instrument should be arranged at steady air current, and two shock-wave detection instrument are arranged on
Sustained height, obtain the relatively accurate value of digging footage；The aerial velocity of wave of shock wave： m/
S, wherein t be tunnel in temperature, unit DEG C.
The present invention benefit be：
1. remote automatic acquisition digging footage outside tunnel is realized, so as to more easily understand construction speed, Ke Yida
To the purpose monitored in real time；
2. not having to exclusively carry out in addition to manual measurement to excavate drilling depth manual measurement, the number that personnel enter tunnel is reduced, section
Human-saving material resources also ensure unimpeded in the safety and tunnel of personnel simultaneously；
The present invention is applied to all mountain tunnels using blasting, can monitor tunnel piercing drilling depth in real time, be
An important ring for constructing tunnel remote real-time monitoring is realized, particularly benefit is more notable in major long tunnel construction, is new shape
The invention and innovation being highly desirable under gesture.
Brief description of the drawings
Fig. 1 is a kind of tunnel piercing drilling depth automatic monitoring system side view based on shock-wave detection instrument.
In figure, 1, shock-wave detection instrument；2nd, construction trolley；3rd, face,
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
During the automatic data collection of tunnel piercing drilling depth, as shown in figure 1, a kind of automatic data collection side of tunnel piercing drilling depth
Method, contain following steps：
Step 1), it is in the construction trolley for making shock-wave detection instrument be arranged at tunnel portal abutment wall position and sustained height
Shock-wave detection instrument (1) is installed, avoids human error as far as possible；
Step 2), after onepull, measure first shockwave signal in air by two shock-wave detection instrument and arrive
Up to the time, and both time difference Δ t are drawn, avoid the temporal error that the attenuation band of shock wave comes to a certain extent；
Step 3), considering that in the case of velocity attenuation, speed is propagated according to shock wave in atmosphere shock wave in atmosphere
DegreeWherein t is temperature in tunnel, unit DEG C, and the time difference Δ t of signal twice,
Calculate the distance S that construction trolley (2) arrives hole1, calculation formula is as follows：
S1=Δ tv
Step 4), repeatedly the distance between measurement construction trolley to face obtains average distance S2；
Step 5) is by the distance S of the construction trolley being calculated to hole1With manual measurement construction trolley to face it
Between distance S2It is added, the as distance L at hole to face.
