FTDM Laser Tunnel Section Meter
I. Instrument Overview
China is a mountainous country, with mountains or heavy hills accounting for 75% of its total land area. To shorten mileage, protect the environment, and save land, tunnel schemes are particularly emphasized in China's mountain infrastructure construction. Excavation is a key process affecting the construction period and cost of tunnel projects. Over-excavation not only increases engineering cost due to the increase in muck output and lining quantity, but also directly affects the stability of surrounding rock due to stress concentration caused by local over-excavation. Under-excavation directly affects the thickness of the lining, thus impacting engineering quality and safety. Various data show that the control of over-excavation and under-excavation has an important impact on the reliability and economic benefits of tunnel structures.
The FTDM series laser tunnel section meter adopts non-cooperative target laser ranging technology and precise angle measurement technology, closely combines polar coordinate measurement method with computer technology, and cooperates with professional graphics processing software, which can quickly obtain the internal contour curve of the closed tunnel space, display the over-excavation and under-excavation values in real time, and also measure the convergence and the amount of excavated earth and rock. It has the function of indicating blastholes, can quickly produce test results and reports without post-processing, and is a very practical engineering measurement tool.
