Abstract

The invention discloses a tunnel section sedimentation and convergence analytical instrument and measuring method. The analytical instrument comprises a semi-circle accurate laser ranging system which is connected with a system host. The system host is fixed on a host carrying plate, a front verticality measuring laser system and a rear verticality measuring laser system are arranged on the front and rear sides of the host carrying plate respectively. A left level bubble and a right level bubble are arranged on the left and right sides of the host carrying plate respectively. A left horizontality fine adjuster and a right horizontality fine adjuster are arranged on the left and right sides of the front verticality measuring laser system respectively. The host carrying plate is fixed on a tripod carrier system. The analytical instrument and the measuring method have the advantages that the front and rear verticality measuring laser systems are arranged on the instrument, so that the consistency and the accuracy of the instrument section before and after measurement are guaranteed; by the aid of the semi-circle accurate laser ranging system, sedimentation or convergence values of 19 measurement points o the tunnel can be measured accurately, and sedimentation or convergence of the tunnel section is monitored effectively.

Description

technical field [0001] The invention relates to the technical field of tunnel section measurement, in particular to a tunnel section settlement convergence measurement and analysis instrument and a measurement method. Background technique [0002] During the excavation and construction of tunnels, geological disasters such as landslides and large deformations of surrounding rocks often occur. The occurrence of geological disasters will lead to casualties, damage to equipment and delay the construction period, which will have a significant impact on tunnel construction. Therefore, in the process of tunnel construction, it is necessary to timely and accurately measure and analyze the settlement and convergence deformation of the surrounding rock, so as to effectively guide the construction and avoid geological disasters and construction accidents. Therefore, it is very important to study the on-site measuring instruments and measuring methods for the surface settlement conver...
