Problems solved by technology

However, before the vibrating construction of the entire steel cylinder, the transportation process of the steel cylinder still faces the following difficulties: (1) When transporting the freighter to the construction site, it is necessary to overcome the influence of hydrometeorological conditions such as ocean currents and waves, and it is very difficult to stand in place; (2) After the floating crane takes out the barrel from the freighter and starts to sink the barrel, the parking space of the floating crane and the positioning barge are restricted by each other

Embodiment Construction

[0028] see figure 1 , figure 2 , image 3 Shown, a kind of steel cylinder vibratory sinking construction of the present invention is stationed hoisting method, comprises the following steps:

[0029] 1. After the transport ship 2 carrying the steel cylinder 1 arrives at the station, four-point mooring is carried out to the transport ship through the anchoring device;

[0030] 2. The floating crane ship 3 travels to the lifting position on the side of the transport ship and anchors it for positioning. The bow of the floating crane ship is connected to the bow and stern of the transport ship through two cross-set towing cables 4 and other anchors to hoist and hold the position. ; And control the retraction of the traction cable by the winch (belonging to the prior art, not shown in the figure) for retracting the traction cable on the floating crane ship, so as to realize the displacement and steering of the floating crane.

[0031] The method of the present invention adopts ...

Abstract

The invention relates to a parking craning method for vibration sinking construction of steel cylinders, in particular to a method by which a cargo ship is parked by an anchoring device and fixed point parking and craning of the cargo ship and moving of craned objects are realized by comprehensive anchoring modes such as crossed traction cables. The method comprises the steps of after the cargo ship carried with the steel cylinders arrives at a parking position, performing four-point mooring on the cargo ship by the anchoring device; anchoring and positioning by driving a floating crane ship to the craning position at the side body of the cargo ship, and forming stable connection between the crossed traction cables at the head of the float crane ship and the head and tail of the cargo ship; craning the steel cylinders by the float crane ship; smartly adjusting the direction of the float crane ship by the anchor cables; controlling the float crane ship to drive to the craning position at the side body of a steel cylinder mounting positioning pier for anchoring and positioning; craning the steel cylinder to the vibration sinking designed position of the steel cylinder in a fixed point mode by the positioning pier through the float crane ship and realizing the vibration sinking location of the steel cylinder by the positioning pier.

Description

technical field [0001] The present invention relates to a parking hoisting method for steel cylinder vibratory sinking construction, in particular to a method of parking a transport ship through an anchor device and realizing fixed-point parking of a floating crane ship through comprehensive anchoring methods such as traction cables arranged crosswise. The method of hoisting steel cylinders and moving objects. Background technique [0002] In recent years, with the development of open sea artificial islands and coastal seawall revetment projects, the enclosure structure formed by vibrating and sinking large-diameter cylindrical structures is rapidly forming islands and embankments. The construction technology is becoming more and more mature, and the application prospects are broad. Steel cylinders are generally bulky, and after processing in large-scale processing plants, they are transported to the construction site by ocean-going freighters; for vibration-sinking construc...
