Embodiment Construction

[0014] The present invention will be further described below.

[0015] A method for accurately and efficiently locating the penetrating parts of marine engineering pipelines according to the present invention specifically includes the following steps:

[0016] First, according to the design drawings, obtain the number of positioning axes in the X direction and Y direction of the project, as well as the name and coordinates of each positioning axis, and construct the positioning grid.

[0017] Then, according to the design drawings, obtain the plane coordinates of the positioning points of the pipeline penetrations.

[0018] Secondly, the absolute coordinate difference between the positioning point of the penetration and each positioning axis in the positioning grid is calculated, and the difference between the absolute coordinates has a sign indicating the relative position of the positioning point of the penetration and the positioning axis. In each direction, compare the ab...

Abstract

The method used for accurate high-efficiency positioning of an ocean engineering pipeline penetration member. The method comprises steps that a number of positioning shafts in an X direction, a number of positioning shafts in a Y direction, the name and the coordinate of every positioning shaft are acquired, and a positioning shaft net is built; the plane coordinate of the positioning point of the pipeline penetration member is acquired; the differences between the coordinate of the positioning point of the pipeline penetration member and the absolute coordinates of the various positioning shafts in the positioning shaft net are calculated, and by comparing the absolute values of the absolute coordinates, a minimum absolute value is determined; the on-site positioning of the penetration member is completed according to the name of the positioning shaft corresponding to the minimum absolute value and the absolute coordinate difference. The method is advantageous in that working time of on-site operators is reduced, working efficiency is improved, and at the same time, a construction error rate is reduced.

Description

technical field [0001] The present invention relates to a method, more specifically, relates to a method for accurately and efficiently locating a penetrating part of an ocean engineering pipeline. Background technique [0002] At present, the positioning of the penetrations of marine engineering pipelines is mostly done by manual calculation and measurement by construction personnel. For general engineering projects, the shortest length is more than 20 meters, and the longest length is hundreds of meters. The construction personnel need to carefully check the positioning point data of the penetrating parts to ensure that the calculation is correct, and then measure and calculate the position of the origin of the coordinate grid to locate the penetrating parts. Cargo location. This work is time-consuming and labor-intensive, and is prone to errors. Once the positioning fails, it will cause rework of multiple processes such as welding, grinding, and touch-up painting, and se...
