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.

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
