Reason software module the relevant information of country rock is handled, if there is information do not meet associated tunnel job specfication, regulation is wanted
The data asked, monitoring and signal processing software module control live acoustooptic alarm system module and issue alarm signal, warning construction
Personnel take care.
Specifically, country rock inner wall displacement measurement is the displacement for monitoring country rock different depth, the loosening of country rock after excavating is judged
Range.Monitoring measurement section is set according to tunnel surrounding geological conditions, 5 gaging holes, hole is arranged in side wall and arch in each section
Deep 3.5-5m, aperture are Ф 50, and every hole buries 3 steel chord type multipoint displacement meters, so that each measuring point is combined closely with the wall of a borehole, rock
It drives measuring point to move together when layer is mobile, measures the displacement of country rock different depth.It is assumed that farthest point layout is in stabilizing surrounding rock
It is interior, and then shift value of each measuring point relative to farthest measuring point can be found out.When the depth of burying degree of farthest measuring point is bigger, originally experience
The influence of excavation is smaller, and measured shift value is closer to absolute value.
Specifically, anchor ergometer is according to tunnel surrounding geological conditions or setting monitoring measurement section, it is all in each section
Radial bore is pressed on side, arranges 5 gaging holes in tunnel-side and arch, the steel chord type bolt shaft of 3 measuring points of installation in each gaging hole

Impact direction is the tangential direction of tunnel contour.
Specifically, needing to be monitored concussion of blasting, using acceleration transducer when Nearby Structure builds tunnel
Dynamometry concussion of blasting.
Specifically, if there is tunnel occur earth's surface infiltration situation, need to seepage pressure, water flow is monitored, and is adopted
Seepage pressure and water flow are monitored respectively with osmometer and flowmeter.Temperature sensor is used to monitor the real-time temperature in Tunnel
Degree.
In the present embodiment, the frequency in the period of automatic collection control module control sensor group acquisition signal and transmission signal
Rate.Automatic collection control module includes sequentially connected timer and controller, and timer is used for acquisition signal period and hair
The frequency for the number of delivering letters carries out timing, controller control sensor group work after reaching the time for controller.Presently relevant rule
Model, regulatory requirements the monitoring period be unable to satisfy the surrounding rock stability monitoring requirement of self-stable ability difference, i.e., artificial monitoring method is not
It can effective monitoring weak surrounding rock stability.Tunnel Excavation Monitoring cycle T is not greater than tunnel stand up time T0, otherwise cannot be effective
Monitor the stability of country rock.The relationship that time and space index from China railways tunnel based on RMR establish can be seen that
The tunnel of 10.5m span, the average stand up time of V grades of country rocks only have 30 minutes, and the stabilization time of IV grades of country rocks also only has 10
Hour.It is therefore to be understood that the speed of surrouding rock deformation speed, the number of monitoring should be enough, if be less than 5 times, surrouding rock deformation
The trend of curve is unobvious, and therefore, monitoring number should not be less than 5 times.Based on analysis above, it can be deduced that monitor the period and enclose
Relational expression between rock stand up time, i.e. stand up time T subtract buries a little before time Ta, should be greater than pendulous frequency multiplied by monitoring cycle this
It is only an adequate condition.According to above analysis, effective monitoring is carried out to rock stability, that is to say, that monitoring
Period must be sufficiently small, should can just be met the requirements using automatic monitoring.Therefore, automatic collection control sensor group acquires IV grades and encloses
The period of rock signal is 20min-3h.Automatic collection control module control sensor group acquire V grades of country rock signals period be
7min-10min.Different grades of Rock Mass to could carry out rock stability using different monitoring cycles effective
Monitoring.
Specifically, the monitoring and signal processing software module include single-chip microcontroller.
As stated above, the present invention is by installing various sensors, real-time automatic collecting country rock in tunnel surrounding monitoring section
Related data, automatic collection control module control sensor acquisition signal period and send signal frequency, pass through communication
Module transfers signals to monitoring and signal processing software module, and monitoring and signal processing software module receive and process data,
And compared with associated tunnel job specfication, the threshold value of regulatory requirements, alarm signal is issued close to or over the data of threshold value,
Warning construction personnel takes care, when something goes wrong, can timely early warning, while also can enter the site of an accident without personnel just
A large amount of relevant information is provided, the safety of system is improved, in addition, other than it can monitor the state of country rock, moreover it is possible to have
Standby positioning function, locating module can obtain the country rock position gone wrong in real time, enable the rapid orientation problem of staff
Position, the present invention can monitor the deformation of the unstable country rock of construction tunnel in real time to be issued on warning information to avoid thing
Therefore generation.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
