A monitoring system and method for tunnel grouting slurry trajectory

Abstract

This application discloses a tunnel grouting slurry track monitoring system, including a monitoring device and a plurality of track data acquisition devices with acceleration inertial navigation sensing capabilities; the monitoring device establishes a wireless communication connection with each track data acquisition device; track data acquisition The device uses the acquisition sensor placed in the grouting fluid to collect its own acceleration inertial navigation information, and uses a wireless multi-hop network to send it to the monitoring device; the monitoring device calculates the trajectory of the trajectory data acquisition device based on the acceleration inertial navigation information, and realizes Tunnel grouting slurry trajectory monitoring. The tunnel grouting grout trajectory monitoring system disclosed in the present application can monitor the flow trajectory of the grouting fluid, thereby realizing timely control of the outflow of the grouting fluid, avoiding the waste of the grouting fluid, and realizing efficient grouting of the tunnel.

Description

technical field [0001] The invention relates to the technical field of engineering monitoring, in particular to a tunnel grouting slurry track monitoring system and method. Background technique [0002] During tunnel excavation, grouting is often used to reinforce the tunnel wall after the shield machine passes through. The gaps or pipes in the direction will lead away a large amount of grouting fluid, and often there is a situation where a large amount of grouting fluid is added, but the rear wall cannot be filled, resulting in a substantial increase in grouting costs. [0003] In the prior art, although ultrasonic CT, electromagnetic wave CT, seismic wave CT, and core drilling method can be used to monitor the quality of grouting. However, these methods cannot be used in the grouting construction process and cannot detect the trajectory of the grout flow. Therefore, if it cannot be found that the state of the rock structure behind the wall is different from that of the op...

Problems solved by technology

However, these methods cannot be used in the grouting construction process and cannot detect the trajectory of the grout flow. Therefore, if it cannot be found that the state of the rock structure behind the wall is different from that of the opening, or there are gaps or pipes in other directions in the tunnel excavation wall The waste of grouting fluid, such as tunnel excavation parts together with caves or underground rivers, these wastes will be staggering
