Embodiment
Referring to Fig. 1, present embodiment provides a kind of crack three-dimensional distortion laser measuring apparatus, is made up of generating laser 1, laser pickoff 5, data processing equipment 9.Launch laser beam 4 directive laser pickoffs 5 during work by generating laser 1.Send signal after control panel 2 sensitization of laser pickoff 1, record the vertical change amount and the left and right sides changing of the relative positions amount in crack simultaneously.Through data line 7 input data processing equipments 9, the data that obtain being correlated with by data processing equipment 9, and simulate the trajectory diagram that the crack relatively moves.
The range ability of the crack three-dimensional distortion laser measuring apparatus of present embodiment preparation is 0~500mm, and precision is 1mm, when the crack deflection reaches critical value, in time sends warning through stop.
Generating laser 1 adopts the MYZOX transmitter, comprises being used to show that stadimeter measures the display control panel 2 of distance; On generating laser 1, mainly contain the length travel receptacle, portable power source, parts such as spirit bubble.Major function is to carry out the mensuration of length travel and send mensuration plane two to the needed laser of displacement.
Generating laser 1 sends the specific laser bundle 4 that wavelength is in infra-red range.Generating laser 1 can use the independent current source power supply, also can supply power through the supply voltage device.The wavelength of laser beam 4 is used for the laser pick-off panel 6 of excitation laser transmitter 5 about 650nn.Wherein, laser pick-off panel 6 receives the laser beam 4 that is penetrated by generating laser 1, obtains induction, be used for display panel laterally with vertical change in displacement.
Laser pickoff 5 is through power supply adaptor power supply, also available portable power source such as power supplies such as accumulator, dry cell.In the present embodiment, laser pickoff 5 is selected commercially available known laser pickoff, mainly by receiving panel 6, air level, data processing chip, communication chip, power supply join agreeable to the taste 8 and adjunct circuit constitute.Wherein, Become rectangle on the laser pick-off panel 6 or exist how much rules arranging the photoelectric sensor that can be triggered; When the laser beam 4 of specific wavelength shines sensor specific on the laser pick-off panel 6; The high level that sensor produced can be positioned at the process chip identification of laser pickoff 5 and send digital signal, measure plane two to change in location.Communication chip through being positioned at laser pickoff 5 sends to the digital signal of being sent among the data processing equipment 9.
Generating laser 1 is supported by tripod 3 with laser pickoff 5, and data processing equipment 9 is connected the signal that transmission laser pick-off panel 2 provides through data line 7 with laser pickoff 5, utilize independently developed software that data are handled.
Generating laser 1 can use tripod 4 to support in the plane, can use the different fixed system to support in concave plane or the special place of geographical conditions or supports.
In actual use, generating laser 1 is placed on the one side in crack, laser pickoff 5 is placed on the another side (as shown in Figure 2) in crack.Generating laser 1 is through after the fixed mechanism fixation, and its position cannot be moved easily, and the laser beam of being sent 4 can be positioned at sensing element in the generating laser 1 to be accepted and discern, to measure the distance apart from laser pickoff 5.The photoelectric sensor that is positioned at laser pickoff 5 is discerned.
Data processing equipment 9 is selected conventional computing machine; Ground fissure is installed in the computing machine detects simulation softward, can receive the digital signal that generating laser 1 is sent, and digital signal is recovered; Simulate the time dependent movement locus in crack, two kinds of forms of output pattern and data.Laser is accepted digital signal that panel 6 sent simulate and reduce, restore the time dependent movement locus of ground fissure, its image output of carrying out two dimension is exported with data, can among dual mode, switch to different needs.And will write down with the process of simulation and preserve, perhaps carry out profound Treatment Analysis in order to shelves.Computing machine is through powerful processing terminal, recovers and simulates ground fissure process over time, data pin carried out the different outputs of figure and digital form to different needs.
Because the ground fissure distortion is a kind of progressive process slowly, following inventor provides a kind of simulation test of simply and efficiently monitoring of the gauge for three directional deformation of ground fissure of the utility model is verified.
1) principle of simulated experiment
Ground fissure with the Xian City, Shanxi Province is a research object, and due to the ground non-uniform settling that the activity of ground fissure causes mainly due to artificial excessive pumping underground water, the inventor has expected that drainage carries out simulated experiment.Generating laser, laser pickoff are placed on respectively in the washbowl in two mutually perpendicular tank A, the B; Through to two mutually perpendicular directions (YZ axle) draining; Drive " drift " of washbowl respectively to the YZ axle; Utilization is different because of the settling amount that the difference of water discharge causes, and reaches the variation of X axle.With the variation on the A groove control XY plane, control the variation on the XZ plane with flowing of B groove water, thereby reach the variation of XYZ three-dimensional, draw from perpendicular displacement, the level of simulating ground fissure in fact and open and the horizontal changing of the relative positions.Cause the skew of gauge for three directional deformation of ground fissure three-dimensional, thereby make and to play the laser change on the laser pick-off panel, and then record the variable quantity of three direction displacements.The drainage simulation test is following:
(1) selects two tanks; After two tanks are all added a certain amount of water; Put the above ground (should select the bigger washbowl of area for use, can guarantee enough buoyancy like this) of two washbowl simulated groundwater, again the generating laser and the laser pickoff of crack three-dimensional distortion laser measuring apparatus are put into two washbowls and leveling respectively; After adjusting the position of washbowl, placement a period of time lets the water surface restore calm.Because the easy undulatory property of water needs enough patience, constantly debugging is operated under the horizontality to guarantee crack three-dimensional distortion laser measuring apparatus.
(2) open the drainage switch of two tanks, the beginning draining.
(3) open the power supply of generating laser and laser pickoff, start working.
(4) generating laser emitted laser bundle; The level of measuring ground fissure is on the one hand drawn tensor; The laser pick-off panel of excitation laser receiver sends signal after the sensitization of laser pick-off panel on the other hand, records the vertical change amount and the left and right sides changing of the relative positions amount of ground fissure simultaneously.
(5) data processing equipment is integrated the displacement of three directions, through the software curve movement of ground fissure that draws.The data that test records are as shown in Figure 3.
2) interpretation:
Because test the variation of simulating displacement through the flow of control water, the fluid and the soil body have evident difference, therefore can cause error unavoidably.But the water simulated experiment, controllability is relatively good, and the flow of adjusting water that can be artificial can be found out through experiment, and the gauge for three directional deformation of ground fissure of enough the utility model of variation ability of displacement displays, and produces a desired effect.
