The conventional method of sedimentation detection is to carry out settlement observation using optical instruments such as theodolite or levels, such method cannot achieve
Real-time monitoring is influenced by sight intervisibility, and the settlement of foundation of upright bar is difficult to observe inside template.
Utility model content
In view of this, the purpose of the utility model is to provide one kind can real-time monitoring, and monitor the high template of accuracy
Support frame optic foundation settlement detector.
The utility model is realized using following scheme: a kind of formwork-support optic foundation settlement detector, including to prop up
The support frame of hold mode plate and more optical fiber grating static water levels, more optical fiber grating static water levels include one and are used as base
Reference of reference optical fiber grating static water level and several monitoring optical fiber grating static water levels to monitor, the monitoring
Optical fiber grating static water level is located at the upright bar lower end side of support frame, and all optical fiber grating static water levels pass through snorkel
It is cascaded with fluid-through tube, all optical fiber grating static water levels are connected by optical fiber with fiber Bragg grating (FBG) demodulator.
Further, the notch positioned at support frame upright bar lower end side, the slot are offered on the ground where support frame
Concrete bed is poured in mouthful, the monitoring optical fiber grating static water level is installed on concrete bed.
Further, the screw rod of three distributions triangular in shape, the monitoring optical fiber light are embedded on the concrete bed
Grid hydrostatic level bottom is provided with the mounting rack being fixedly connected on screw rod, and the mounting rack is hollow rectangular parallelepiped structure,
The bolt hole with screw rod cooperation is offered on the downside of mounting rack, the monitoring optical fiber grating static water level is bolted to connection
Have on mounting rack.
Further, the fiber Bragg grating (FBG) demodulator and computer equipment wired connection, the computer equipment are also connected with
There is precaution device.
Compared with prior art, the utility model has the following beneficial effects: the utility model formwork-support ground is heavy
Drop monitoring device, which solves conventional method in the market, can not observe the observation of template settlement of foundation in real time, be difficult to template inside ground
The problems such as observation point measures can be realized and carry out high-precision real-time monitoring to the absolute settlement of monitoring point ground, effectively
The generation that template is collapsed with unstability accident is taken precautions against, security risk is excluded in time, guarantees the personal safety of construction worker.
For the purpose of this utility model, technical solution and advantage is more clearly understood, specific embodiment will be passed through below
And relevant drawings, the utility model is described in further detail.
