Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a caisson turning support apparatus for safely and reliably transporting and installing a caisson having a small free space and a small buoyancy.
[0002]
[Prior art]
Small caissons used for breakwaters and mooring berths may have less free space for droughts or may have low caisson buoyancy. When navigating these caissons with little free space and caisson with low buoyancy, the hoisting vessel is lifted to assist the buoyancy. However, when a caisson used for port construction on a remote island or the like is manufactured on the mainland or the like, the cruising distance becomes long in many cases, and safety at the time of cruising becomes a problem, and a lot of cost is required in terms of cost. For this reason, there are various designs for caisson with little free space and caisson with small buoyancy, and the safety and cost are being compared for the navigation method.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to provide a caisson turning support device that can safely and reliably transport and install a caisson having a small free space and a caisson having a small buoyancy, and that is inexpensive and easy to attach and detach.
[0004]
[Means for Solving the Problems]
The present invention is suspended to two ships buoyancy barge, and caissons to provide a possible caisson temporary置架stand Ueno, a caisson temporary置架table raising and lowering the adjustable platform hoist winches provided on buoyancy barge, two vessels The buoyancy trolley is equipped with a caisson cruise support device using a gantry system that is provided with a balloon for fixing caissons on each side of the ship that opposes the buoyancy trolley, and a pontoon connection winch that can draw the two buoyancy trolleys together .

DETAILED DESCRIPTION OF THE INVENTION
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a caisson cruise support apparatus using a gantry system according to the present invention will be described below with reference to the drawings.
[0006]
FIG. 1 is a front view showing the concept of the device. This device suspends a caisson temporary mount 2 with a cable 9 on two buoyancy pedestals 3 and the caisson 1 on the caisson temporary mount 2. The caisson temporary mounting base 2 can be mounted on the buoyancy carrier 3 with a base hoisting winch 4 that can be adjusted up and down via a cable 9.
[0007]
Next, FIG. 2 is a front view of the caisson turning support apparatus according to the gantry system of the present invention, FIG. 3 is a plan view thereof, and FIG. 4 is a side view thereof.
[0008]
The caisson 1 is placed on the caisson temporary stand 2 positioned between the two buoyancy trolleys 3. The air compressor driven by the portable generator 7 is placed on the buoyancy trolley 3. 8, and a balloon 6 for fixing the caisson 1 is provided on each of the opposing ship sides of the two buoyancy trolleys 3. Air is injected into the balloon 6 from the air compressor 8. As shown in the figure, two buoyancy trolleys 3 are interposed by interposing balloons 6 infused with air on both sides of the caisson 1 and on opposite sides of the two buoyancy trolleys 3. A trolley connection winch 5 that pulls them together with a connection cable 10 is provided.
[0009]
In FIG. 2, the right half indicated by arrow A indicates the state when caisson 1 is mounted on caisson temporary mount 2, and the left half indicated by arrow B indicates caisson temporary mount 2 for adjusting the draft of caisson 1. The state where it is raised by the stand hoisting winch 4 is shown.
[0010]
Next, the procedure for assisting the navigation of the caisson 1 using the apparatus of the present invention will be described. First, in FIG. 5, the caisson temporary mounting base 2 is lowered by lowering the cable 9 and the caisson 1 is temporarily placed. In this state, as shown in FIG. 6, the caisson 1 is drawn and placed on the caisson temporary stand 2.
[0011]
Next, the caisson 1 is lifted by hoisting the caisson temporary mounting base 2 with the base hoisting winch 4 as shown in FIG. 7, and further, as shown in FIG. The caisson 1 is fixed by injecting air from the air compressor 8 into the balloon 6 as shown in FIG.
[0012]
In this state, the caisson 1 is towed to a predetermined towed position by a tow boat or the like, but during that time, the caisson 1 is fixed via the balloon 6, so that it is safely held during the tow. In other words, the balloon 6 functions to protect the caisson 1 and also serves to assist buoyancy during cruise.
[0013]
It should be noted that when the caisson 1 is lowered from the state shown in FIG.
[0014]
【The invention's effect】
According to the caisson cruising support device of the present invention described above, it is possible to safely and reliably transport and install a caisson with a small margin of psoriasis or a caisson with a small buoyancy. The apparatus is relatively inexpensive as compared with the conventional system, and the caisson can be easily attached and detached.
[0015]
Further, in the device of the present invention, the caisson is crushed with the caisson fixing balloon interposed therebetween, so that the caisson is protected from swaying during cruising, and is not damaged, making the caisson safer. To tow.
