Underwater fence board preparation and positioning installation method and underwater fence board positioning installation system

Abstract

The invention discloses an underwater fence board preparation and positioning installation method and an underwater fence board positioning installation system. The underwater fence board preparationand positioning installation method comprises the following steps that (1), fence board preparation is performed, specifically, a formwork is prepared, a bottom mold and side molds are installed, steel bar binding is performed, concrete is poured, mold removal is formed, fence board transportation is performed, a fence board is transported to a dock by a heavy carrying car, and the fence board islifted and placed on a transport ship by a gantry crane; and (2) the fence board is positioned and installed, specifically, the transport ship is berthed to an installation ship; a shipborne crane uses a hanging bracket to lift the fence board, and the fence board is lifted to the installation side; the lifting machine starts to lower the fence board; a scanner is turned on to display the actual real-time position of the fence board on a display screen of a main controller; the main controller controls a lifting hook to perform automatic and hydraulic unhooking, and a next fence board is installed; and an installation system includes the lifting machine, four GPS and two scanners, wherein the lifting machine, the four GPS and the two scanners are installed on a hull. The underwater fence board preparation and positioning installation method has a simple preparation process, convenient installation and positioning and high precision.

Description

technical field [0001] The invention relates to the field of fence board preparation and installation, in particular to an underwater fence board preparation, positioning and installation method and an installation system thereof. Background technique [0002] At present, the preparation of fence panels is very complicated and costly. In addition, when installing deep-water fence panels, a combination of square barge cranes is often used to lift the fence panels for installation. Measure the floor and place the fence board installation sideline. Since the operator of the crane cannot observe the position of the fence board in the water, there is no way to accurately locate the installation position of the fence board. It is necessary for the divers to cooperate underwater. The installation position of the board is accurately positioned, and the fence board is placed in the correct position. This method requires the cooperation of divers, which has certain safety risks, and ...

[0002] At present, the preparation of fence panels is very complicated and costly. In addition, when installing deep-water fence panels, a combination of square barge cranes is often used to lift the fence panels for installation. Measure the floor and place the fence board installation sideline. Since the operator of the crane cannot observe the position of the fence board in the water, there is no way to accurately locate the installation position of the fence board. It is necessary for the divers to cooperate underwater. The installation position of the board is accurately positioned, and the fence board is placed in the correct position

This method requires the cooperation of divers, which has certain safety risks, and the use of divers to assist in the installation of fence panels will increase the construction cost of fence panel installation
