Description
Technical field
The invention belongs to technology for deformation monitoring fields, and in particular to a kind of crack three direction displacement monitoring measuring device.
Background technique
In hydraulic engineering, after water conservancy reservoir filling, with increasing for reservoir level, the pressure of water acts on concrete surface
On plate, concrete slab will be deformed with massif connecting sewing, cause panel two sides that can generate the deformation in three directions, i.e. panel
Relative to the changing of the relative positions of massif, the sedimentation displacement that panel is compressed due to the effect of waterpower to dam body, due to the effect panel phase of waterpower
The physical quantity monitored required for being exactly for the displacement that massif gap is opened, these three displacements.
Three-direction gap detector hydraulic structure field use relatively broad, range that however, it is not limited to this, many bridges,
The geotechnical engineerings such as subway ship lock, tunnel, high slope also have extensive demand and application.
There are mainly two types of the Three-direction gap detectors of structure in engineering application at present:
(1) structure is first is that a kind of based on a monoblock type Three-direction gap detector structure for face combination
As shown in Figure 1, marked in the figure: 1- universal joint；2- displacement meter；3- adjustment screw；Angle block gauge of the 4- with universal joint；5-
Displacement meter support；Hold-down support on 6- panel；7- fixing threaded hole；8- stops the hold-down support on plate；9- A-frame.3
Crack gauge one end is fixed at 1 point, is mounted on the side in crack, and the other end of 3 crack gauges is fixed in a mounting bracket, peace
Mounted in the other side in crack, measurement is completed by carrying out rigid connection to crack gauge both ends, obtained data can not be directly anti-
X, Y, Z axis displacement variable is reflected, needs quadratic formula calculating that can carry out data analysis.
It is had the following disadvantages based on a monoblock type Three-direction gap detector (structure one) for face combination:
1. the data of measurement cannot be used directly, need quadratic formula to calculate, error is larger: three direction displacement monitoring device is opposite
What is answered is to measure the change in displacement of X, Y, Z axis, and 3 crack gauges and X, Y, Z axis that existing measuring device is fixed are due to fixation
The reason of structure, can not intuitively reflect the displacement of three axial directions in different angles, gained measured value.In engineering application
It needs to carry out conversion by solid geometry and trigonometric function formula and obtains corresponding displacement variable, since there are three-dimensional space
Change in displacement, that is, allow to calculate change in displacement it is also extremely complex, there are biggish errors.
2. the instrument measured value in three directions influences each other, error is larger: existing measuring device when X, Y, Z axis any one
Direction is subjected to displacement variation, and driving simultaneously 3 sensors, deformation occurs, and variation is in irregular stereoeffect.Such as
When fruit only has single axial to be subjected to displacement variation, wherein 2 sensors are in tensional state, 1 sensor is in compressive state,
Can have compressed sensor can not work normally in loose condition (of surface), the normal work of equipment be influenced, so as to cause measured value
There are large errors.
3. equipment overall structure is larger, place smaller scope of application: existing equipment overall volume is larger, is only applicable to space
More open perhaps both ends have larger plane crack at carry out Embedded installation in some narrow side slopes or gallery then by
Being limited to objective condition can not install, and there are limitations for the scope of application.
4. instrument is fixedly connected, link is more, and measured value accuracy is low, and error is larger: existing structure crack gauge both ends use ten thousand
It is fixed on bracket and support to section, crack gauge is attached by installs fixture and connecting rod by screw thread, and there are connections
Link is relatively more, and there are certain gaps for universal joint and each junction, will affect specific measuring value accuracy, generate measurement
Error.
5. mounting bracket volume is larger, installation difficulty is big: being all uneven, and existing at the crack of usual engineering site
Structure Three-direction gap detector bracket requires both ends mounting surface to must assure that crack end flat is concordant, and frame bottom anchors plate suqare
It is very big, it needs to choose opposed flattened end face when engineering construction is buried and is cleared up, or pour a smooth embedded end
Face, it is more demanding for engineering construction, increase the difficulty of installation.
(2) structure is second is that a kind of based on a split type Three-direction gap detector structure for face combination
As shown in Fig. 2, the label in Fig. 2: 1- instrument mounting bracket；2- sensor；3- measuring block；4- protective cover.Such as Fig. 2
The side for mounting bracket being fixed on crack is shown, 3 sensors, calibrating block cloth are set along X, Y, Z axis direction respectively above
It sets in the other side in crack, the slide bar thimble of 3 sensors is held out against in 3 planes of calibrating block using the elastic force of spring, this 3
A plane is orthogonal, and when crack deforms, slide bar thimble carries out planar slide, each sensor point in calibrating block
The displacement variable in oneself representative direction is not measured.
It is had the following disadvantages based on a split type Three-direction gap detector (structure two) for face combination:
1. probe measurement modular construction will affect measured value in sliding or even damage instrument: probe measurement structure and instrument are drawn
Bar directly passes through screw thread rigid connection, and in translation gliding, pull rod is due to that can be generated deviation, serious meeting by side-friction
It causes the measuring steel wire of instrument sensing unit to be deformed, measured value is caused to be abnormal even without measured value.
2. probe assembly cannot achieve sealing and dustproof, easy card plug is used for a long time and leads to not measure: existing probe measurement knot
Component, which cannot achieve, to be fully sealed, and in engineering long-term use process, probe assembly is easy to float into dust, is accumulated dirt, is led to group
Situations such as Caton, blocking occur inside part, makes probe assembly fail, and when crack deforms, probe can not be under the action of the spring
Deforming simultaneously can not continue to work normally, and measurement is caused to be failed.
3. probe measurement modular construction is complex, more demanding to assembly crewman's technical level: probe measurement component is complete
Portion is fragmentary accessory, requires when assembly instrument pull rod that cannot have a rotation, and assembly crewman needs the training by profession can be compared with
Good completion assembly.
4. mounting bracket volume is larger, installation difficulty is big: being all uneven, and existing at the crack of usual engineering site
Structure Three-direction gap detector bracket requires both ends mounting surface to must assure that crack end flat is concordant, and frame bottom anchors plate suqare
It is very big, it needs to choose opposed flattened end face when engineering construction is buried and is cleared up, or pour a smooth embedded end
Face, it is more demanding for engineering construction, increase the difficulty of installation.
