There is also other identical elements.
Such as Fig. 1 and shown in Figure 3, in the specific embodiment of the present invention, a kind of shield ground settlement is proposed
Automatic monitoring and alarming system, principle are as follows: do not influenced by shield driving above the tunnel axis promoted with same level
Point installs a hydrostatic level 1 respectively, then is separately connected automation collection electronic box 2, so that it may acquire shield cutter distance prison
The sedimentation value of monitoring point when measuring point different distance, automation collection electronic box pass data to the end PC by wireless transmission, pass through
Processing routine on PC draws time-history curves.
In the present invention, two hydrostatic levels 1 use Beijing base Kanggong department BGK-4675 hydrostatic level, are mounted on ground
Table.
In the present invention, described two hydrostatic levels 1 connect tracheae 3 by top, middle part connects tracheae 4 and lower part connects
Water receiving pipe 5 connects, and three root canals guarantee that two hydrostatic level inside water pressures are consistent with air pressure, it is ensured that aqueous vapor pressure balance.
In the present invention, automation collection electronic box 2 integrates automatic data logging kit, the BGK- produced using Beijing base Kanggong department
DR automatic data logging kit calculates the 32 channel BGK-M work CRO distributed network measurement systems using the production of Beijing base Kanggong department
System.
Automatic monitoring and pre-alarming method using shield ground settlement automatic monitoring and alarming system of the invention is as follows:
(1) sample collection: in the operating condition progradation of shield machine normal fluctuation, automated collection systems are arranged in advance, in advance
Collecting sample time-history curves initial value；
(2) it determines standard time-history curves upper and lower limit: sample time-history curves group is drawn according to sample time-history curves initial value,
And then obtain upper and lower envelope, it is pre- as early warning system respectively as the standard time-history curves upper limit and standard time-history curves lower limit
The subsidence range value of alert program；
(3) settlement monitoring: the tunnel axis earth's surface monitoring point of different distance in front of the corresponding cutterhead of standard time-history curves
Automated collection systems are laid respectively, the sedimentation value of each monitoring point in cutterhead front during acquisition and monitoring shield driving；
(4) shield machine operating condition is assessed: if the sedimentation value of different distance monitoring point is without departing from standard time-history curves in front of cutterhead
The upper limit or lower limit of upper corresponding position illustrate that current shield machine operating condition is good, can be used as the reference operating condition promoted for a long time；
(5) automatic early-warning: if the sedimentation value of cutterhead front different distance monitoring point, which exceeds on standard time-history curves, corresponds to position
The upper limit or lower limit set then illustrate that current working exception, early warning system receive corresponding information, issue early warning automatically.
The meaning of time-history curves are as follows: during shield driving, earth's surface measuring point in front of shield with shield driving, measuring point away from
The sedimentation value curve at shield different distance moment is known as time-history curves.
Before the change of shield machine operating condition in the case where shield machine operating condition normal fluctuation, automated collection systems are arranged in advance, are adopted
Collection measures the sample time-history curves initial value of several monitoring points away from cutterhead different distance, as early warning system early warning program
Subsidence range value.
Sample is divided into five stages: rank before leading infection stage, cutterhead reach according to slope variation range by the present invention
Section, shield body pass through stage, long-term settlement stage after stage, shield tail abjection.Since time-history curves have consistent rule, and shield machine
Parameter fluctuation can be such that actual measurement time-history curves fluctuate within the scope of two envelopes, be made respectively by the upper and lower envelope of sample drawing
For the standard time-history curves upper limit and the standard time-history curves upper limit.Actual sample acquisition can be acquired flexibly according to live desirability
In five stages some, certain is several or all corresponding stage monitor values are used as sample cluster, obtain the standard time-history curves upper limit with
Standard time-history curves lower limit, the subsidence range value as the end PC early warning program.
Above-mentioned acquisition system takes initial value and removes, and is re-arranged to the position for needing to monitor and adjust shield machine operating condition
It sets.
The tunnel axis earth's surface monitoring point of different distance is laid automatically respectively in front of the corresponding cutterhead of standard time-history curves
Acquisition system is specifically laid several sets and is determined according to actual conditions, at least lay it is a set of, system can flexibly with shield driving gradually
It is moved along tunnel mileage, remains and earth's surface in front of shield cutter is monitored.
It needs in due course to be finely adjusted shield machine operating condition according to the concrete condition of shield during shield, early warning system can
Shield machine operating condition after fine tuning is assessed.If the sedimentation value of different distance monitoring point is bent without departing from standard time-histories in front of cutterhead
The upper limit or lower limit of corresponding position on line illustrate current shield machine operating condition, that is, the shield machine operating condition after finely tuning is good, can be used as length
The reference operating condition that phase promotes；If the sedimentation value of different distance monitoring point is beyond corresponding position on standard time-history curves in front of cutterhead
The upper limit or lower limit, then the shield machine work condition abnormality after illustrating fine tuning, early warning system receive corresponding information, issue early warning automatically.
Simultaneously can according to measured sedimentation value transfinite degree as next again fine tuning operating condition foundation, again to operating condition into
Monitoring and warning system re-starts monitoring and warning after row fine tuning, and so circulation promotes.
During shield driving, as shield is more and more closer apart from monitoring point, same monitoring point can be with shield distance not
Together, in the different time-history curves stages, early warning bound can also change as shield moves closer to monitoring point.
Position of the monitoring point monitor value on corresponding time-history curves exceeds in front of the cutterhead that early warning system receives when the end PC
The standard time-history curves upper limit or standard time-history curves lower limit, the end PC program issue red early warning automatically.
The sedimentation value in different time course curve stage is in by earth's surface monitoring point in front of monitoring shield cutter, with shield machine
It is more and more closer apart from measuring point, it can be realized real-time dynamic monitoring, whether the next operating condition of shield machine at this time of reversely verifying is reasonable, especially
When needing to finely tune shield machine operating condition, shield machine operating condition problem can be found, adjustment in time in advance, be prevented whereby
Security risk.
So far, though those skilled in the art will appreciate that the exemplary reality that present invention has been shown and described in detail herein
Example is applied, still, without departing from the spirit and scope of the present invention, still can be directly determined according to the present disclosure
Or derive many other variations or modifications consistent with the principles of the invention.Therefore, the scope of the invention should be understood and defined as
Cover all such other variations or modifications.
