Problems solved by technology

[0002] When the block is installed underwater, the posture may change due to water surges or collisions, and it is impossible to ensure that the block posture can be checked and adjusted in time when the posture changes, and the block posture is controlled throughout the process, and it is impossible to ensure that the block is in place. The posture and occlusion between adjacent blocks meet the requirements

Embodiment Construction

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0017] According to an embodiment of the present invention, an underwater visual Core-Loc block installation monitoring method includes the following steps: using GPS-RTK real-time dynamic positioning, setting the horizontal and vertical positioning accuracy of the GPS-RTK receiver, which can be 5mm±1ppm , the RTK measurement parameters are corrected on-site through the pre-arranged elevation control points, and the GPS mobile receiver station is set on the top of the crane boom. The receiver data line is connected to the crane control room, and the computer navigation and positioning software is used for positioning; the GPS-RTK receiver of the present invention can be installed on the top of the 250t crawler boom t...

Abstract

The invention relates to an underwater visual Core-Loc block installation monitoring method, which comprises the following steps: adopting GPS-RTK real-time dynamic positioning, setting horizontal and vertical positioning precision of a GPS-RTK receiver, carrying out field correction on RTK measurement parameters through a pre-arranged elevation control point, arranging a GPS mobile receiver station at the top end of a crane jib, and carrying out underwater visual Core-Loc block installation monitoring. During construction, the Core-Loc block, the suspension wire and the receiver are kept on the same straight line, a data line of the receiver is connected to a crane control room, and computer navigation positioning software is used for positioning; according to the Core-Loc block binding mode, the mounting posture of the block is changed in advance by randomly and alternately using two binding and buckling modes and changing three binding and buckling lifting points, the lifted Core-Loc armor block can be changed into six postures, and the posture inconsistency between the adjacent blocks can be well achieved; according to the technical scheme, the posture of the blocks in the hoisting process is kept consistent, the occlusion performance and the installation density of the blocks are improved, meanwhile, safety in the hoisting process is guaranteed, and the requirement for inconsistent nesting and posture of the blocks in the traditional process can be met.

Description

technical field [0001] The invention relates to the technical field of Core-Loc block installation and construction, in particular to an underwater visual Core-Loc block installation monitoring method. Background technique [0002] When the block is installed underwater, the posture may change due to water surges or collisions, and it is impossible to ensure that the block posture can be checked and adjusted in time when the posture changes, and the block posture is controlled throughout the process, and it is impossible to ensure that the block is in place. The posture and occlusion between adjacent blocks meet the requirements. [0003] Therefore, how to provide an underwater visual Core-Loc block installation monitoring method, to meet the construction requirements of different directions and postures between adjacent Core-Loc armor blocks, and to ensure the hooking between adjacent Core-Loc armor blocks The effect and the technological method to ensure the overall stabi...
