Self-adhesive reflective film description

Reflection sheet size: 20 × 20] [mm, [40 × 40] mm, [60 × 60]
Select the appropriate measurement tool enables you to do more with less = self-adhesive reflective film is that you complete the survey work the best tools.
In a conventional survey work to be done a job is directed, you need to run the ruler who go to the backsight prism or rack set up signs, not only need someone to do it, but also to spend the appropriate time; your work may often encounter many places it is difficult to assume that a prism, or difficult to reach, or you need to spend a lot of time and effort to frame a good prism, even worse is that often go to these points erecting prism, with the self-adhesive reflective film what the problem is more easily solved.
For instance,
1, in the dense steel mesh in erecting prism is difficult.
2, on the road in the busy erecting prism is dangerous.
3, tunnel construction deformation observation
4, bridge construction in deformation observation
If your job is to conduct deformation monitoring, the need to go regularly to the point of erecting prism deformation, and this process tends to continue for some time, self-adhesive reflective film can solve your these annoying things, just pay a small fee, you can make once and for all your work, greatly improving the efficiency of your work.

Wide range of applications: Tunnel Engineering

Self-adhesive reflective sheet
Wide range of applications

Tunnel

In the construction of the tunnel surrounding rock deformation observation convergence using reflective film, you do not need time to set up observation points prism; steel arch docking tunnel center line calibration, orientation, etc. work using reflective sheet also greatly facilitate the work.

Subway Project

With self-adhesive reflective sheet for subway construction of buildings and ground deformation observed displacement observation, cavern-oriented measurements. Monitoring operation of the subway also be used.

Bridge Engineering

Used in bridge construction stakeout, arch stitching, displacement observation and bridge operation process of displacement measurement. These do not need a lot of time and then to a known point on the mirror set.

Construction

Construction, there are dense steel mesh and scaffolding, can be found through visual observation position has been very difficult, erecting prism is difficult work. Self-adhesive reflective film easily solve this problem.

Routine measurements

In the rear-view orientation, free station and other work using a self-adhesive reflective sheet, saving a run-foot rear view member station while saving time.

Slope Monitoring

Slope monitoring, there are a large number of points need to regularly measure the deformation, these points are either difficult to reach, or set to mirror the difficulties, the use of self-adhesive reflective film greatly simplifies the work.

Ships measurement

Large vessels of the manufacturing process is the final survey work correctly spliced ​​guarantee. The large number of observation points, distributed to all parts of the hull, some difficult to reach, and some hard erection prism.

Three-dimensional laser scanning

Three-dimensional laser scanning ultimate goal is to restore the space of real objects 3D models. Scan multi-station work is often done in order to graphic stitching, you need a certain number of feature points are arranged as tie points.

Close-range photogrammetry

Close-range photogrammetry bad but at key places the texture feature points are arranged in order of stitching pattern, you need a certain number of feature points are arranged as tie points. Self-adhesive reflective film is a good choice.

Special measurement

In the high-voltage wires, high temperature and other dangerous places or difficult laid prism, or where people should not stay long in place, with the self-adhesive reflective sheet alternative prism.

Instrument calibration

Instrument in the course of routine requires regular inspection and adjustment, for example, I angle, C angle, the laser beam collimation axis is coaxial with the other. Using self-adhesive reflective sheet is not required after each re-laid inspection field.

Measure the distance to meet most of the measurement tasks
If a prism measurement mode measurement, measuring range can reach 250 meters, if the prism measurement mode measurement, measuring range can reach 1300 meters. (This data is for all models of Leica Total Station, Total Station other brands, this data is slightly different.)
Advantages: compact, convenient placement
Self-adhesive reflective sheet with 20 × 20mm, 40 × 40mm, 60 × 60mm variety of specifications, self-adhesive reflective film followed by a sticker, pasted directly to the desired object can be observed.
Durable
Self-adhesive reflective film can be used in most work environments, under normal circumstances the sun and rain years after the initial measurement range can reach 50% of the general measurement cycle, the measurement range is almost no change.
Low cost, suitable for long-term laid
As the cost is very low, do not worry about stolen stolen, can require long-term observation of objects laid on top.
In the wild or underground engineering aiming to facilitate
Because self-adhesive reflective film also has diffuse functions, such as at night or low light underground engineering work environment at the site as long as the direction of a target with a flashlight to shine, you will find a very bright highlights - self-adhesive reflective film, no need to use a prism operations torch lighting prism.
For a variety of instruments ranging goniometer
All total station, Ranging can use, only need to set up different instruments for different prism constant can be. Whether your product is already discontinued, or the latest products, you can use self-adhesive reflective film.
