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 indicationfunction, and also to complete tunnel profile lofting work.
 Product features:
 

• SD*3 laser tunnel detector uses laptop computer as a controller conveniently to interact between human and computer on the site and to improve the efficiency; with the high precision angle encoder and ranging sensors, to make tunnel detector accuracy increased 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*3 type multi-functional laser tunnel cross-section detector is not only keeping the original SD*2 series section testing function, but also having other new functions, such asfront and back areasection measuring, working faceblasthole arrangement and surrounding rock deformation measurement etc.
