A pipe joint installation positioning control system and method

Abstract

The invention relates to the technical field of engineering measurement, in particular to a pipe joint installation positioning control system and method. The pipe joint installation positioning control system provided by the present invention includes: a positioning device installed on the installation ship, used to obtain the position parameters of the positioning device; The relative positional relationship of hauling, and the installation relative positional relationship between the pipe joints to be installed and the installed pipe joints; the control device is used to determine the current position of the pipe joints to be installed according to the data measured by the positioning device and the sonar measurement and control device, and Output correction parameters according to the current position and the preset position of the pipe section to be fixed to correct the current position. This system installs the positioning device on the installation ship, uses the positioning device and the sonar measurement and control device to locate the pipe joint to be installed, so as to avoid the deformation of the measuring tower in the water and affect the positioning accuracy of the pipe joint to be installed, thereby improving the installation and positioning control of the pipe joint the accuracy.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a pipe joint installation positioning control system and method. Background technique [0002] With the progress of society and the development of science and technology, pipe section tunnels are more and more widely used in water transportation projects. The pipe section method tunnel construction is to sink the prefabricated pipe sections into the water and excavate the trenches in advance. A construction method in which pipe joints are assembled and connected together in water. [0003] At present, the total station method and the GPS method are commonly used methods for locating pipe joints in the water-saving sinking and docking construction. These two methods usually install a measurement tower at the beginning and end of the pipe joint, and set up a GPS positioning system or a prism on each measurement tower to perform absolute positioning of the pipe join...

AI Technical Summary

Problems solved by technology

Although the absolute coordinates of the pipe joints can be measured by the total station method or the GPS method, as the distance between the pipe joints to be installed and the installed pipe joints continues to shrink, the water entry depth of the pipe joints gradually increases. Deformation will cause a deviation between the actual coordinates of each feature point on the pipe joint and the coordinates calculated according to the results of the total station method or GPS method, which will affect the connection between the pipe joint to be installed and the installed pipe joint. The positioning accuracy of the pipe joints, resulting in a decrease in the installation and positioning accuracy of the pipe joints
