Measuring and Controlling System and Method for Underwater Attitude of Pipe Sections

Abstract

The invention relates to a system and a method for measuring and controlling underwater attitudes of pipe sections, particularly to a measurement and control system and method which is used for guiding and adjusting the sinking and abutting attitudes of the pipe sections through a GPS (Global Positioning System) receiver, a sonar device and a central processing unit. The sonar device is adopted and can be used for performing real-time positioning on the pipe sections to be installed in the sinking process and performing real-time positioning on the relative position relation between the pipe sections to be installed and the installed pipe sections in the abutting process and accordingly the problem of the sinking and abutting measurement and control of the pipe sections in the deep water can be effectively solved and accordingly the real-time attitude adjustment of the pipe sections in the deep water environment is achieved, the construction cost is saved, and the working efficiency is improved.

Description

Technical field [0001] The invention relates to a measurement and control system and a measurement and control method for the underwater attitude of a pipe section, in particular to a measurement and control system and a measurement and control system for guiding and adjusting the sinking and docking attitude of the pipe section through a GPS receiver, a sonar device and a central processing unit method. Background technique [0002] At present, the underwater tunnel for vehicles to travel is formed by connecting multiple immersed pipes. The volume and weight of the immersed pipe are quite large, generally about 100-200 meters in length. The immersed pipe is laid on a pre-laid foundation bed. When installing large-size immersed pipes, the method of hanging the immersed pipe through the sling cable by the installation ship is mostly used; however, this method requires high precision in the settlement and docking of the immersed pipe, and the corresponding control is very difficult...

Problems solved by technology

When installing large-scale immersed tubes, the method of hanging the immersed tubes by the installation ship through the sling cable is mostly used; however, this method requires high precision for the settlement and docking of the immersed tubes, and the corresponding control is very difficult, and it is very difficult for the tubes to save water. The measurement and control of the lower attitude is an important guarantee to ensure the smooth placement and docking of the immersed tube

The measuring tower method can be used to measure and control the underwater posture of the immersed tube when constructing in shallow water depth areas, but the height of the measuring tower is limited, and the measuring tower may be completely submerged underwater when constructing in deep water depth areas. Therefore, it is necessary to use a deep-water measurement and control system to measure and control the underwater attitude of the immersed tube; but there is no such system that can perform deep-water measurement and control, and there is no corresponding method of using this system for measurement and control.
