Description

A kind of tunnel piercing drilling depth automated watch-keeping facility and method
Technical field
The present invention relates to a kind of tunnel piercing drilling depth automated watch-keeping facility and method, belong to Tunnel Engineering technical field.
Background technology
At present, greatly developing with China's traffic infrastructure, Tunnel Engineering quantity are continuously increased, particularly western mountain The substantial amounts of Tunnel Engineering of section planning, wherein it is major long tunnel to have considerable part.During constructing tunnel, tunnel internal feelings 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 Data processing module;The first shock-wave detection instrument is fixedly mounted on tunnel portal abutment wall position, the second shock-wave detection instrument It is fixedly mounted in the construction trolley of face;First shockwave signal in the data processing module collection air The time of two shock-wave detection instrument is reached, and draws both time difference Δ t;And speed is propagated according to shock wave in atmosphere V and twice the time difference Δ t of signal are spent, calculates the distance S that construction trolley (2) arrives hole1
S1=Δ tv
Data processing module is by the distance S of the construction trolley being calculated to hole1With manual measurement construction trolley to the palm The distance between sub- face S2It is added, the as distance L at hole to face;
L=S1+S2
The automatic monitoring method of described device, comprises the following steps:
1) the first shock-wave detection instrument is installed at tunnel portal abutment wall position, and in the construction trolley (2) close to face The second shock-wave detection instrument of upper installation;
2) after onepull, when measuring first shockwave signal arrival in air by two shock-wave detection instrument Between, and draw both time difference Δ t;
3) according to the shock wave spread speed v and time difference Δ t of signal twice in atmosphere, construction trolley (2) is calculated To the distance S at hole1
S1=Δ tv
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.
L=S1+S2
Each development blasting drilling depth automatic data collection, makes remote synchronization outside tunnel obtain tunnel piercing drilling depth, so as to more square Just understand construction speed, the purpose monitored in real time can be reached.In addition, do not have to exclusively carry out in addition to demarcation to excavate drilling depth people Work measures, and reduces the number that personnel enter tunnel, improves safety for tunnel engineering and uses manpower and material resources sparingly simultaneously.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted, And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
