A system and method for monitoring the amount of broken stones in the riprap pipe of an underwater leveling machine

Abstract

The invention discloses a system for monitoring the amount of crushed stones in a rock-pipe of an underwater leveling machine, which includes an optical sensor group, a pressure gauge group, a comprehensive acquisition instrument and a computer system. The optical sensor group includes at least two optical sensors, which are respectively installed on the At the highest position and the lowest position of the design debris volume of the riprap tube, the pressure gauge group includes at least two pressure gauges, which are respectively installed at the highest position and the lowest position of the design debris volume of the riprap tube. The pressure gauge and the optical sensor will collect The real-time data and signals are transmitted to the computer system through the integrated acquisition instrument, and the computer system processes the real-time data and signals to obtain the height of the top surface of the gravel in the riprap tube during the working process of the underwater leveling machine and output it to the output device. The invention also discloses a method for monitoring the amount of crushed stones in the riprap pipe of the underwater leveling machine using the monitoring system. The output result of the invention is accurate and reliable, and can greatly improve the leveling operation efficiency.

Description

technical field [0001] The invention relates to a system and a method for monitoring the amount of broken rock in a riprap tube, in particular to a monitoring system and a monitoring method for the amount of broken stone in a riprap tube of an underwater foundation leveler for an immersed tube tunnel. Background technique [0002] With the continuous development of immersed tube technology, more and more cross-river and sea-crossing passages in China are in the form of immersed tube tunnels. The advantages of shallow burial depth and large cross-section allow a short transition section of road and tunnel to connect the two banks. It is the most suitable form of cross-river and cross-sea passage in the prosperous central city. [0003] One of the most important links in the construction of immersed tube tunnel is the leveling treatment of the immersed tube foundation. In the pre-excavated foundation groove, a layer of gravel cushion with a diameter of 20-60mm is laid. The gr...

Problems solved by technology

When transporting stones into the riprap pipe, the water body is abnormally turbid and the visibility is extremely low. It needs to be left to stand until the water body becomes clear to observe, which greatly affects the accuracy of monitoring and work efficiency
