Problems solved by technology

[0003] The traditional positioning of the caisson is assisted by a large crane. The principle of air flotation of the barrel-type components of this structure is different from that of the caisson. The whole process depends on the air pressure in the cabin, and the force is basically in the vertical direction. Since the crane ship cannot Ensure that the force of the double hooks is even and coupled with the effect of water surges, the bucket is extremely unstable under the action of the lifting force, and it is difficult to achieve safe and fast positioning

Embodiment Construction

[0016] The specific technical solutions of the present invention will be further described below with reference to the accompanying drawings, so that those skilled in the art can further understand the present invention, without limiting their rights.

[0017] refer to Figure 1-3 , a double-vessel pull-to-position method for a breakwater bucket-type component, the bucket-type component includes a bottomless and covered oblong barrel body 13 and two anti-wave barrel bodies arranged above the oblong barrel body 13 9. The wave-proof barrel body 9 is arranged along the short axis direction of the oblong barrel body 13, and the oblong barrel body 13 is divided into nine compartments 15 by two vertical and horizontal partition walls 14, and each compartment 15 The top is provided with exhaust holes 16 and drainage holes 6, and the two anti-wave barrels 9 are equipped with an operating platform 10, and the four corners of the operating platform 10 are equipped with GPS data collecto...

Abstract

The invention discloses a double-ship counter-pulling positioning method of a breakwater barrel type component. The method comprises the following steps: when the tide level is high, a main pulling ship is arranged on one side of the barrel type component, a positioning ship is arranged on the other side of the barrel type component, the centers of the two ships and the barrel type component are arranged on the same straight line, three groups of anchor machines are arranged on each of two ships, each group comprises two anchor machines, each group of anchor machines at two ends of the positioning ship are connected with positioning anchors via cross mooring ropes, a group of anchor machines in the middle are connected with the barrel type component via the cross mooring ropes, two groups of anchor machines in the main pulling ship are arranged on the left side and the right side respectively and are connected with the positioning anchors via two open mooring ropes, the other group of anchor machines are arranged at the ship bow and are connected with the barrel type component via the cross mooring ropes so as to counter pull the barrel type component; when the distance between the barrel type component and the mud surface is 1.3-1.7m, the barrel type component is taken to the mounting position for waiting for falling of the tide; when the distance between the barrel type component and the mud surface is 0.5-0.8m, the barrel type component is accurately positioned, exhausts and sinks at the same time; the barrel type component drains water and sink after the barrel type component touches the mud until the sinking depth of the barrel in the mud is 2.0-3.0m, then the positioning is completed. Through the double-ship counter-pulling positioning method of the breakwater barrel type component, the barrel type component is safely and quickly positioned and mounted via counter pulling of double ships.

Description

technical field [0001] The invention relates to a port protection project, in particular to a method for positioning a breakwater barrel-type component by pulling two ships against each other. Background technique [0002] The barrel member of the existing breakwater is a new type of breakwater structure made of concrete, steel bars, steel structures and other materials. This type of structure consists of a base barrel member with no bottom and a cover and two anti-wave barrel members. The barrel-type components of the structure are submerged through a semi-submersible barge and then air-floated. After air-floating, they need to be dragged to the installation position. [0003] The traditional positioning of the caisson is assisted by a large crane. The principle of air flotation of the barrel-type components of this structure is different from that of the caisson. The whole process depends on the air pressure in the cabin, and the force is basically in the vertical directio...
