SD-4 laser tunnel detector

Product Description

Product usage:
The instrument is not only to detect the current section, but also to detect the forward or backward section;
Surrounding rock deformation measurement functions: the instrument can detect all kinds of deformation, such as convergence, subgrade subsidence, slope deformation and arch bridge displacement and deformation; blasthole indication function, and also to complete tunnel profile lofting work .
 Product features:
SD*4 laser tunnel detector uses laptop computer as a controller conveniently to interact between human and computer on the site and to improve the efficiency; Adopt the precise measuring single axis independent decoding technology of the Leica tachometer measurement robot to realize the dual-core biaxial spin control. Precision and testing time has qualitative leap compared with the similar industry products. With German technology ranging sensors, the measurement accuracy is up to tachometer measurement level.
Can store standard section, and can calculate and display the back break results at real-time
Professional post-processing software operation is very simple, and can automatically generate professional reports
Report form is different, and can meet different users’ requirements
Post-processing software can automatic set the page margins and page numbers in printing graphics reports. To ensure the test report unify with the whole inspection unit test report format. Greatly to shorten the detection unit time for report graphic processing.
SD*4 type multi-functional laser tunnel cross-section detector has new functions, such as front and back area section measuring, working face blasthole arrangement and surrounding rock deformation measurement etc.
