Due to the fact that the geology and long-term human activities often form partial underground cavities, the underground cavities can cause deformation of tunnel rock formations or highway subgrades, and great potential safety hazards exist. For the detection of the underground cavity, a reliable detection method is adopted to clarify the size, the burial depth and the like of the cavity, and flexible treatment measures are adopted for different cavity conditions, so that the effects of safety, economy and rationality are achieved. Before reasonable treatment is adopted for the cavity, whether the cavity is widened or not needs to be found in time, namely whether rock stratum at the top end of the cavity falls or not.
In the related technology, by equidistantly arranging the magnetic coils on the hole wall of a hole vertically penetrating through a karst or goaf roof and suspending a magneto-electric sensor in the hole, when the karst or goaf roof collapses, the magnetic coils fall together, the magneto-electric sensor generates induction current in the falling process, the magneto-electric sensor converts the induction current into an electric signal and then transmits the electric signal to a signal processor of a signal processing device through a signal amplifier, the signal processor automatically collects and analyzes the falling time of the magnetic coils and the collapse thickness of the roof, calculates the collapse frequency of the roof and the residual thickness of the roof strata, and when the thickness of the residual roof strata reaches the set critical collapse thickness or the collapse frequency reaches the preset critical collapse frequency, the signal processor controls an alarm and sends the alarm system to a mobile terminal through a GPRS wireless transmitter, so that the aim of monitoring the collapse degree of the karst or goaf roof is finally achieved.
However, the problem is also that the scheme can detect the situation that surrounding rock collapses, when karst or goaf roof collapses, the magnetic ring falls along with the karst or goaf roof, the magnetic ring causes the magneto-electric inductor to generate induction current in the falling process, and when the magnetic ring falls, the follow-up collapse situation of the surrounding rock cannot be detected continuously, so that maintenance staff can not confirm the concrete situation of cavity collapse.

However, it will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In some instances, well known methods, procedures, systems, components, and/or circuits have been described at a high-level so as not to obscure aspects of the present application with unnecessary description. It will be apparent to those having ordinary skill in the art that various changes can be made to the disclosed embodiments of the application and that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application. Thus, the present application is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the scope of the application as claimed.
Referring to fig. 1, an embodiment of the application discloses a rock stratum deformation monitoring method, which is applied to rock stratum deformation monitoring equipment, the equipment comprises a terminal server 10 and a first detection module 20, the terminal server 10 is arranged in a rock stratum maintenance part, the first detection module 20 is arranged in a rock stratum to be detected, the first detection module 20 is used for detecting the descending condition of the rock stratum to be detected so as to generate a detection signal, then the first detection module 20 sends the detection signal to the terminal server 10, and the terminal server 10 analyzes the acquired detection signal so as to detect an underground cavity in the rock stratum to be detected, thereby realizing corresponding maintenance treatment.
Referring to fig. 2, a formation deformation monitoring method includes the steps of:
s100, periodically acquiring detection signals corresponding to the rock stratum to be detected, and acquiring the thickness of the rock stratum to be detected according to the detection signals.
The rock stratum to be measured represents a rock stratum corresponding to a tunnel rock stratum or a highway subgrade, the detection signal represents a detection signal corresponding to the rock stratum to be measured, and the thickness of the rock stratum to be measured represents the distance from an underground cavity corresponding to the rock stratum to be measured to the ground.
It should be noted that, because the thicknesses of the rock layers to be measured are different, and thus the signal strengths of the detection signals acquired by the terminal server 10 are different, the terminal server 10 acquires the corresponding thicknesses of the rock layers to be measured by detecting the signal strengths.
In conjunction with fig. 3, specifically, the method for obtaining the thickness of the rock stratum to be measured according to the detection signal includes the following steps:
s110, obtaining the corresponding signal intensity value according to the detection signal.
And S120, the signal intensity value is screened out the interval distance corresponding to the signal intensity value in a preset database.
And S130, taking the interval distance as the thickness of the rock stratum to be measured.
The signal intensity value represents the intensity value of the detection signal, the preset database stores the signal intensity value corresponding to the detection signal and the interval distance, the interval distance is stored in the distance in the preset database, and the interval distance represents the distance corresponding to the signal intensity value one by one.
The preset database is a preset database in which data are obtained according to signal forcing values corresponding to detection signals obtained by adjusting the interval distance, the data are counted to form a preset database in which signal intensity values and interval distances are in one-to-one correspondence, and the obtained detection signals are used for further obtaining the signal intensity values corresponding to the signal intensity values, so that the interval distances corresponding to the signal intensity values can be obtained in the preset database, and the obtained interval distances are used as the thickness of the rock stratum to be measured.
S200, comparing the thickness of the rock stratum to be measured with a preset thickness value.
S300, if the thickness of the rock stratum to be measured is larger than a preset thickness value, judging that the rock stratum to be measured has a descending risk, and periodically acquiring the descending distance of the rock stratum to be measured according to the thickness of the rock stratum to be measured and the preset thickness value.
The preset thickness value represents the thickness value when the rock stratum to be measured does not sink, and the falling distance represents the sinking distance of the rock stratum to be measured. Specifically, the terminal server 10 compares the thickness of the rock stratum to be measured with the preset thickness value, when the thickness of the rock stratum to be measured is greater than the preset thickness value, the terminal server 10 determines that the rock stratum to be measured has a descending risk, and periodically obtains the descending distance of the rock stratum to be measured according to the thickness of the rock stratum to be measured and the preset thickness value so that the terminal server 10 can obtain the descending distance of the rock stratum to be measured in real time.
It should be noted that, since the preset thickness value represents the thickness value when the to-be-measured rock stratum is not sunk, the thickness of the to-be-measured rock stratum corresponding to the to-be-measured rock stratum detected by the terminal server 10 is equal to the preset thickness value at the beginning, so that when the thickness of the to-be-measured rock stratum is equal to the preset thickness value, the terminal server 10 may not perform any operation, but when the thickness of the to-be-measured rock stratum is detected to be smaller than the preset thickness value, it is indicated that the rock stratum deformation monitoring device may be damaged, and maintenance personnel are required to perform maintenance detection on the rock stratum deformation monitoring device so as to be capable of more accurately monitoring the to-be-measured rock stratum sunk.
It should be noted that, in order to monitor the sinking process of the rock stratum to be measured in real time, the terminal server 10 needs to obtain the actual sinking process of the rock stratum to be measured, specifically, periodically obtain the sinking distance of the rock stratum to be measured according to the thickness of the rock stratum to be measured and the preset thickness value, and the method includes the following steps:
s310, taking the difference value between the thickness of the rock stratum to be measured and the preset thickness value as the descending distance.
In another embodiment, for the underground cavity corresponding to the rock stratum to be measured, the rock stratum to be measured does not sink, but directly processes the formed underground cavity, and although danger is avoided in advance, the rock stratum to be measured does not sink, so that a certain maintenance effort is wasted, and maintenance on other underground cavities with danger may be missed. If only the sinking process of the rock stratum to be measured is monitored by light, in the one-down sinking process of the rock stratum to be measured, if the underground cavity cannot be maintained in time, larger loss can be caused.
Referring to fig. 4, in order to reasonably arrange maintenance personnel to maintain the underground cavity formed by the rock stratum to be measured, after periodically obtaining the descending distance of the rock stratum to be measured according to the thickness of the rock stratum to be measured and the preset thickness value, the method further comprises the following steps:
s400, comparing the falling distance with a preset falling interval.
S500, if the falling distance is larger than the preset falling interval, generating and sending out a first processing signal.
S600, generating and sending a maintenance instruction according to the first processing signal.
The first processing signal represents a signal for judging that a hole to be repaired corresponding to the rock stratum to be detected needs to be subjected to emergency processing, and the maintenance instruction represents an instruction sent to a maintenance central control and is used for warning maintenance staff of the maintenance instruction of the rock stratum to be detected.
It should be noted that, if the descent distance is smaller than the preset descent interval, it means that the degree of the stratum to be tested sinking does not need to be maintained at this moment, and only needs to be observed continuously, of course, when the descent distance is equal to the preset descent interval, the terminal server generates and sends out a first processing signal, and the stratum to be tested is maintained.
Referring to fig. 1 and 5, in another embodiment, the formation to be measured may be wholly or partially submerged, and emergency treatment needs to be performed on the underground cavity 50 when wholly submerged, and the treatment process is different for different submerged states, and when partially submerged, a safe part may exist, so that only the submerged part needs to be actively treated.
Here, it should be noted that the formation deformation monitoring apparatus further includes a second detection module 30, where the second detection module 30 includes a second laser sensor 31 and a third laser sensor 32, where the second laser sensor 31 includes a second laser transmitter 311 and a corresponding second laser receiver 312, and where the third laser sensor 32 includes a third laser transmitter 321 and a corresponding third laser receiver 322. The second laser transmitter 311 is disposed opposite its corresponding second laser receiver 312, and the third laser transmitter 321 is disposed opposite its corresponding third laser receiver 322. The second laser sensor 31 is disposed near the top of the underground cavity 50 corresponding to the rock formation to be measured, and the third laser sensor 32 is disposed adjacent to the second laser sensor 31 and along the vertical direction.
In connection with fig. 6, after generating and issuing the first processing signal, the following steps are also included:
s510, periodically acquiring a first width signal of the rock stratum to be measured, and acquiring a feedback signal according to the first width signal.
S520, acquiring a falling state corresponding to the rock stratum to be detected according to the feedback signal, wherein the falling state comprises synchronous falling and asynchronous falling.
S530, if the falling state is synchronous falling, generating and sending out a first processing signal.
S540, if the falling state is asynchronous falling, generating and sending out a second processing signal.
The feedback signal comprises a first specified signal and a second specified signal, wherein the first specified signal represents a signal received when the rock stratum to be tested sinks synchronously, and the second specified signal represents a signal received when the rock stratum to be tested sinks asynchronously and drops for a specified distance. The second processed signal characterization warns maintenance personnel of the signal that requires primary processing of the cavity.
Specifically, the terminal server 10 receives the first width signal generated by the second laser transmitter 311, the terminal server 10 sends the first width signal to the second laser receiver 312 and the third laser receiver 322, when the second laser receiver 312 and the third laser receiver 322 receive the first width signal, both respond to the first width signal and send a feedback signal to the terminal server 10, and the terminal server 10 processes the feedback signal to obtain a falling state corresponding to the rock stratum to be measured, and if the falling state is synchronous falling, the terminal server 10 generates and sends a first processing signal. If the drop state is asynchronous drop, the terminal server 10 generates and issues a second processing signal.
In another embodiment, in order to accurately obtain the corresponding falling state of the rock stratum to be tested, it is necessary to reasonably obtain how the rock stratum to be tested is sunk, so that maintenance personnel can reasonably arrange to maintain the underground cavity 50 of the rock stratum to be tested.
Acquiring a falling state corresponding to the rock stratum to be detected according to the feedback signal, wherein the falling state comprises the following steps:
s521, judging whether the feedback signal is the first specified signal.
S522, if the feedback signal is the first specified signal, determining that the falling state corresponding to the rock stratum to be detected is synchronous falling.
S523, if the feedback signal is not the first specified signal, judging whether the feedback signal is the second specified signal.
S524, if the feedback signal is the second specified signal, determining that the falling state corresponding to the rock stratum to be tested is asynchronous falling.
Specifically, the terminal server 10 receives the first width signal generated by the second laser transmitter 311, the terminal server 10 transmits the first width signal to the second laser receiver 312 and the third laser receiver 322, and when the second laser receiver 312 receives the first width signal, the second laser receiver 312 responds to the first width signal and transmits a first specified signal to the terminal server 10, and when the third laser receiver 322 receives the first width signal, responds to the first width signal and transmits a second specified signal to the terminal server 10.
It should be noted that, since the second laser receiver 312 is disposed opposite to the second laser transmitter 311, when the terminal server 10 receives the first width signal and receives the first specified signal again within the specified time, it is indicated that the rock stratum to be measured above the underground cavity 50 is either not sunk or sunk as a whole. Since the first processing signal is generated and sent by the terminal server 10 in this embodiment, it is only determined that the rock formation to be measured is synchronously sinking.
When the terminal server 10 receives the first width signal and receives the second specified signal within the specified time, it indicates that the stratum to be measured on the upper layer of the underground cavity 50 sinks on the side close to the second laser transmitter 311, and thus, it is determined that the stratum to be measured sinks asynchronously.
It should be noted that, when the terminal server 10 receives the second width signal sent by the third laser transmitter 321 and the terminal server 10 receives the feedback signal sent by the second laser transmitter 311 within the specified time, the terminal server 10 determines that the rock stratum to be measured on the upper layer of the underground cavity 50 is sunk near the side of the second laser receiver 312, and thus determines that the rock stratum to be measured is asynchronized sunk.
In another embodiment, when the maintenance personnel performs processing, the maintenance personnel can perform corresponding processing on the emergency situation in time when the emergency situation is met. Therefore, when it is just found that the underground cavity 50 needs to be repaired, the terminal server 10 makes a corresponding treatment scheme according to the current condition of the rock stratum to be tested, and sends the treatment scheme to the repair staff in the first time, so that the repair efficiency of the underground cavity 50 of the rock stratum to be tested by the repair staff can be improved.
After the falling state corresponding to the rock stratum to be detected is obtained according to the feedback signal, the method further comprises the following steps:
s550, acquiring soil data of the cavity to be tested;
s560, acquiring a processing scheme according to the soil data and the falling state, and judging the falling state of the rock stratum to be tested;
s570, if the falling state is synchronous falling, the first processing scheme is sent to maintenance personnel and a command for making emergency processing is generated;
and S580, if the falling state is asynchronous falling, sending the second processing scheme to maintenance personnel for subsequent processing.
The soil data represent soil layer data corresponding to the cavity to be tested, the treatment scheme comprises a first treatment scheme and a second treatment scheme, the first treatment scheme represents an emergency treatment scheme, and the treatment scheme is higher in priority. The second processing scheme characterizes a lower priority processing scheme.
Here, the priorities corresponding to the first processing scheme and the second processing scheme are different, and it is the same how the maintenance of the underground cavity 50 may be implemented, and the first processing scheme and the second processing scheme correspond to soil data around the underground cavity 50.
