Fig. 3 monitors principle of work and the relative settlement curve of vertical displacement with electronic horizontal ruler.
Embodiment
In the Ziyahe River South Road sinking engineering construction digging process, show according to theoretical analysis and empirical data, because soil body unloading effect, the disturbing influence of below subway Line 1 underground railway track is the inhomogeneous stressed of the vertical displacement of underground railway track and underground railway track structure with main manifestations.Be the vertical displacement situation of Real-Time Monitoring subway Line 1 underground railway track, adopt electronic horizontal ruler that automatic monitoring is carried out in the vertical displacement of underground railway track longitudinal profile.Automatically gather Monitoring Data by collector, for the safe operation of Subway Line 1 underground railway track provides measured data.
The automatic monitoring of subway Line 1 underground railway track vertical displacement
(1) principle: utilize and measure the instrument electronic horizontal ruler that underground railway track tilts, with they a plurality of being used in conjunction, with the vertical displacement in monitoring underground railway track longitudinal profile.
(2) singularity
Owing to be subjected to the restriction of underground railway track service time of subway Line 1, be difficult to carry out for a long time continuous manual measurement, for guaranteeing its safety, determine in monitoring range, to adopt the electronic horizontal ruler of U.S. SLOPE INDICATOR company and the vertical displacement automatic monitoring system that corresponding CR series data automatic collector forms, carry out Real Time Monitoring.
(3) Instrument structure
EL BEAM is the instrument of the measurement object tilt (being the point-to-point transmission discrepancy in elevation) of U.S. SLOPE INDICATOR company release.
The core of electronic horizontal ruler is an electrolyte inclination sensor (Fig. 1, Fig. 2).It is to utilize electrolyte to carry out the instrument that horizontal departure (being the pitch angle) is measured, its distinguishing feature is that the sensitivity of angle measurement is very high, can reach 1 second (being equivalent on 1 meter ruler because the inclination angle that two ends have 5 microns discrepancy in elevation to form), and fabulous stability is arranged.
Above-mentioned electrolyte inclination sensor (assembly) is installed in the hollow rigidity ruler, has just consisted of electronic horizontal ruler (EL Beam).Electronic horizontal ruler can singly prop up installation during use, also the joining end to end of branched electric surveyor's staff can be formed one " chi chain ", launches to install along direction to be measured in the monitoring section.
(4) principle of work
The core of electronic horizontal ruler is an electrolyte inclination sensor, and its sensitivity of measuring the pitch angle was up to 1 second.Above-mentioned electrolyte inclination sensor is installed in the hollow ruler, has just consisted of electronic horizontal ruler (EL Beam Sensor).Blade length can be set as required, is installed on the underground railway track railway roadbed (works) with crab-bolt.Then obliquity sensor is returned to zero, and be locked in this position.The sedimentation meeting of railway roadbed (works) changes the inclination angle of beam, and settling amount (d) by formula " L (sin1-sin0) " is calculated.Herein, L is the length of beam; The 1st, current inclination angle value; The 0th, first primary dip value.If a series of electric surveyor's staffs are installed on the underground railway track structure of underground railway track on vertically end to end, forms above-mentioned what is called " chi chain ", just can draw the interior vertical displacement curve of " chi chain " scope.The visible Fig. 3 of its principle.
(5) automatically gather
Electrolyte inclination sensor in the electronic horizontal ruler can be exported according to the variation at inclination angle the voltage signal of corresponding proportion.The signal of " chi chain " upper each electrolyte inclination sensor output is all received on the CR series data automatic collector, just can by the time interval of setting (adjustable scope is several seconds to several hours, generally desirable one hour) to the sensor of all accesses reading of once sampling.The data of each sampling reading gained are temporarily stored in the collector for regularly processing, also can directly be transported to the computing machine from collector by cable, in computing machine, by predefined program voltage signal is converted into the inclination angle angle, length (L) according to the chi body calculates settling amount di (i props up chi in " i " expression chi chain) again, utilizes the method for vector addition can obtain the interior real-time vertical displacement curve (Fig. 3) of chi chain scope.
(6) composition of monitoring system
The vertical displacement automatic monitoring system is by being located at the electronic horizontal ruler on the underground railway track vertical structure and being installed in CR series data automatic collector on the underground railway track sidewall nearby with electronic horizontal ruler, and is located at that main control computer forms in the nearest Site Office.
The output signal of each electronic horizontal ruler is received on nearby the data acquisition unit with cable, and data acquisition unit is with the signal cable of a RS232 interface link to each other with main control computer (also can adopt the wireless network connected mode).Main control computer is located at Site Office interior (determining according to field condition) nearby.The settlement automatic monitoring system can automatic operation once setting, but also can make manual control into by operating personnel at any time.
Special control software is housed in the main control computer, finishes the functions such as data transfer, arrangement calculating, deposit and in real time demonstration monitoring figure.
The data acquisition time interval can and revise in main control computer control during system works.Can adopt 15 minutes interval in the reality, automatically all electronic horizontal rulers be carried out a data acquisition and just can meet the demands.Every collection one secondary data, just at once computing, and a result who gathers shows at screen with figure or form.
Utilize software that the vertical displacement control criterion of underground railway track is set in advance, in case practical distortion surpasses this scope, native system has automatic alarm and warning function.
