Problems solved by technology

[0005] In the case of long underwater slopes, harsh wind and waves, and poor underwater visibility, using the polar coordinate method or GPS positioning installed on the crane, the traditional method of diver-assisted installation is inefficient, and the safety of divers is also lacking.

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention provides an imaging system for installing an armor block of a breakwater and an application technique thereof. A three-dimensional image sonar is used for continuously scanning underwater, positioning coordinates are obtained by a positioning unit, the kinematic error is corrected by an attitude sensor, and a physical model is resolved by a computer so as to generate a three-dimensional diagram containing coordinate information and guide the installation construction of the armor block. A sonar real-time imaging technique is used for installing the underwater armor block of the breakwater, so that frequent positioning and underwater measurement and touch of divers can be omitted, a large amount of time is saved, and the safety risk is reduced; an accurate positioning result is guaranteed by self attitude correction, the influence of wind wave on construction can be effectively reduced, blocks can be accurately put and are hooked and connected with each other, the density and direction can be controlled, the installation quality of the blocks is increased, the wave resistant capability of the breakwater is guaranteed, and a crane operator can know complete information of the armor block, information asymmetry and misunderstanding from the computer in the whole installation process, so that the construction accuracy is greatly guaranteed.

Description

technical field [0001] The invention relates to the technical field of breakwater slope management construction, in particular to an imaging system for installing breakwater face protection blocks and its application technology. Background technique [0002] The new container terminal project of Tema, Ghana is located on the west side of Tema Port, the largest man-made seaport in Africa. The total length of the project breakwater is 3558 meters, and it is a slope type riprap structure with a maximum water depth of 16m. The outer slope of the breakwater adopts 300kg-500kg cushion stones, 2-5t face protection stones and 2m 3 Protective structure of the face armor block. The maximum length of the installation slope of the armor block is 21.8m, of which the 12.5m long slope is located below the extremely low water level of 0.00m. [0003] The face armor block used in the project is ACCROPODE II type face armor block, which is an improved version of ACCROPODE Ⅰ type face armor...
