Immersed tube freeboard monitoring system and method

Abstract

The invention relates to an immersed tube freeboard monitoring system and method, and belongs to the technical field of immersed tube floating transportation, and the immersed tube freeboard monitoring system comprises a measurement assembly, a data transmission module and a server; the measuring assembly is installed on the side portion of the immersed tube and comprises a pile casing and a pressure sensor fixedly installed in the pile casing, and the pile casing is provided with a through hole so that seawater can enter the pile casing to make contact with the pressure sensor. The data transmission module is installed on the top of the immersed tube and electrically connected to the pressure sensor so as to transmit pressure data measured by the pressure sensor. The server is arranged in a master control room and is in communication connection with the data transmission module so as to receive pressure data measured by the pressure sensor; the server is provided with a calculation module, and the calculation module is used for calculating the freeboard of the immersed tube according to the pressure data measured by the pressure sensor. The immersed tube freeboard monitoring system can automatically monitor the immersed tube freeboard in real time in the immersed tube floating transportation process, the measurement precision is high, and the measurement risk is low.

Description

technical field [0001] The invention belongs to the technical field of immersed tube flotation, and in particular relates to a system and method for monitoring the freeboard of a immersed tube. Background technique [0002] Immersed tube freeboard is defined as the difference in height between the top surface of the immersed tube and the water surface when the immersed tube is in water. During the floating installation of immersed tubes, it is necessary to measure the freeboard data around the tube sections of the immersed tubes, so as to ensure that the anti-floating coefficient of the immersed tubes meets the requirements and ensure the construction safety of the whole cycle of the floating installation of immersed tubes. [0003] At present, the freeboard of the immersed tube is measured manually with a tape measure. This measurement method not only fails to transmit data in real time, but also the measurement data is inaccurate and the data measurement error control is d...

[0003] At present, the freeboard of the immersed tube is measured manually with a tape measure. This measurement method not only cannot achieve real-time data transmission, but also the measurement data is inaccurate, and it is difficult to control the data measurement error. At the same time, the measurement personnel are exposed to the On the top surface, there is a greater safety risk in water-facing measurement operations
