Description

{A pulling up method of sunken body under the sea}

The present invention relates to a method of lifting a deep-sea sinker, more particularly, to a method of lifting a deep-sea sinker, comprising the steps of: precipitating a plurality of H files in a sectional shape (round, oval, H file, and then a girder or strut corresponding to the lateral pressure is installed on the inner side wall of the work space made of the H file, so that it is not affected by the flow velocity and water pressure during deep water underwater operation, And to a method of lifting.

As is well known, in general, when a sinking object such as a ship or an aircraft is sunk in a water such as a sea, a river, a lake, or the like, the depth of the sinking water is not deep enough to allow the diver to dive, If the depth of the water is 40 ~ 60m or more, or the float of the mud floats on the bottom of the sea floor is blurred and the working distance can not be secured, The diver could not get into the water, and there was no proper equipment to salvage the sinkholes that were sunk in deep water, so the sinkholes that were sunk in deep water could not salvage.

Since the sinking bodies that are immersed in the deep water as described above can not be lifted and the sinking bodies are left in deep water, the damage caused by the property damage and the oil leaking from the sinking bodies are very large This is the current situation.

Also, if a human accident occurs, it must be very sensitive to the way of getting up with the survivors and may spread to social disasters.

Accordingly, in order to solve such a problem, the deep sea sinking lifting method of Patent No. 10-365260 has been developed. In the lifting method, the weight weight 9 is weighted, the bottom surface excavator 12 is attached, A fluid injector 19 is used to form a pit in the front and rear of the lower part of the cone, and a sink chain is inserted through the pit to fix the cone and then towed by a crane.

However, in the deep-sea salvage method, when the weight of the sinking body is large, when the pit is formed at the front and rear sides of the lower part of the sinking body by using the high-pressure fluid injector 19, the sinking body collapses into the pit due to its own weight, And secondly, the conventional deep-sea salvage method has a problem that the operation is hardly possible because it is difficult for the bird to be positioned at a precise position with respect to weight in a severe region.

In addition, even if the sinking body exists at a depth sufficient for the deep-sea divers to work, there is a problem that the operation time of the diver is very limited in the high-altitude region and the time and cost are rapidly increased.

FIG. 2 is a view showing a state where a structure is installed through a deep sea sink lifting method according to an embodiment of the present invention. 4 is a front sectional view showing a single-file installation structure of a deep sea sink lifting structure according to an embodiment of the present invention, FIG. 5 is a cross- 1 is a flowchart illustrating a flow of a method for lifting a deep sea sinker according to an embodiment.

In accordance with an embodiment of the present invention, a method for lifting a deep sea sinker is provided in which a plurality of H files are set up in a circumferential shape (round, oval, rectangular) And struts (Strut: 14) corresponding to the lateral pressure are installed in the side wall of the work space made of the H file, so that it is not influenced by the flow velocity and the water pressure in the deep water underwater operation It is a fast and safe way to work.

In accordance with one embodiment of the present invention, a method of lifting a sinkhole sinker according to an embodiment of the present invention can be used to salvage a sinkhole from a shallow coastal coastal area, .

Once in a region with a high flow rate, deep-sea divers are almost impossible to work, and even if they do work, the working time is very short, which can be very costly to salvage.

In order to solve such a problem, the method of lifting the deep sea sinker according to one embodiment of the present invention is a method in which a safe, economical and quick lifting is accomplished by using a water film method.

More specifically, the method for lifting the deep sea sinker according to an embodiment of the present invention forms the structure 1 so as not to be disturbed by the operation due to the flow rate during operation of the sinking body 2.

The structure 1 may be composed of a plurality of structures depending on a cost range or a working time for a work. Fig. 4 shows a single-order structure, and Figs. 2 and 3 show a double-order structure.

The order structure is a structure for blocking the periphery of the casting body 2 from the outside seawater and can realize two cases of draining the inner space of the structure 1 and not draining the inner space of the structure 1 have.

If you drain the internal space, you can work comfortably without diving. If you do not drain the internal space, the deep-water diving will dive, but it will not be affected by the algae.

First, as shown in Fig. 1, the H file 8 hanging on the crane of a crane line 6 anchored on the water surface is settled to the surrounding seafloor of the sunken body 2. During the process of fixing the H-file 8 to the original ground 4 before the H-file 8 is settled to the surrounding seabed of the sunken object 2, the sunken object 2 is affected It is further necessary to fix the immersed body 2 to the ground.

It is also possible to perform a welding operation on the crane wire 6 so that the entire length of the H file 8 can be equal to or greater than the ground surface 4 while sinking the H file 8 to the surrounding seabed of the sinking body 2 And the H file (8) is settled while carrying out the H file (8).

In this state, as shown in FIG. 4, a plurality of the H files 8 are installed on the circular ground 4 so that the circular structure 1 is formed to surround the surrounding space of the sunken object 2 Install it.

At this time, when the H file (8) is installed on the ground board (4), it can be installed through a hovering device or installed on the ground through a jack. At this time, a separate chemical solution may be injected through the grouting method so that the H file 8 can be more strongly cemented to the paper cloth 4, so that the binding force between the paper cloth 4 and the H file 8 can be further strengthened .

In this state, the waterproof partition 16 is installed between the H files 8 to form the structure 1. Preferably, the surface of the H file 8, The rubber packing? 50 to? 100 is press-fitted.

Next, a girder and a strut 14 are installed on both inner side walls of the H-file 8, and a girder or strut 14 is connected to an external water pressure To generate the side pressure and the transverse-pressure stress.

On the other hand, the work plate 12 is provided on the H file 8.

In this state, the boat is directly raised with a crane, and the towing rope is fixed to the casting body 2 to tow it.

On the other hand, if the inside of the structure 1 is to be drained as shown in FIG. 4, a pumping device is installed on the working plate 12 and the inside of the structure 1 is drained. Then, the inside of the sink is cleaned and the cargo is collected.

Water is injected into the ballast tanks of the sunken bodies 2 to dispose several water partition walls 16 of the structure 1 to water the inside of the structure 1 .

2 and 3, the method further includes a step of installing a sheet sheet 10 in addition to the structure shown in FIG. 4, and installing the water sheet 11 on the sheet 10.

The structure 1 shown in FIGS. 2 and 3 can be improved in safety because the working space is less influenced by the algae, and the space formed by the water barrier ribs 16 is separately formed outside the water barrier ribs 16 A separate space made up of a water receiving sheet 11 and a seawater having a water surface lower than the water surface and higher than the internal space of the water level partition wall 16 is accommodated in the separate space, (16) The work space in the inside can receive less water pressure and thus work safer.

The seat 10 is formed at a position spaced apart from the space defined by the aft partition 16 to form a circular structure as shown in Fig. ) To establish the order.

If the depth from the water surface to the sinking body 2 is 45 meters, preferably the water surface height of the space formed by the water barrier ribs 16 and the water receiving sheet 11 is preferably 35 meters, 16) is formed to be 15 meters in depth so that the divers can easily be submerged.

FIG. 6 is a front sectional view showing another file installation structure of the deep sea sink lifting method according to an embodiment of the present invention, and FIG. 7 is a plan view showing a state in which an order partition is installed in the file of FIG.

When the H file 8 is installed, if the depth of the sinking body is about 40 m to 60 m, a large hovering equipment is required to install the H file 8 on the paperboard 4 in a hovering manner .

Therefore, in the present invention, by providing the structure shown in Fig. 6, the H file 8 can be installed more easily and quickly.

First, when hunting with the hunting equipment is performed to install the H file 8, the hitting force of the H file 8 is transmitted to the nearby ground, causing waves in the water to cause collapse of the ground board 4 around the hit point .

In addition, the H-file (8) requires a large equipment for the hanger because of its length, and it is necessary to work on the barge or work on the deck in order to connect short files by the welding method. However, this is also very troublesome and time- There were disadvantages. In addition, in the case of underwater welding, since it is a hard work, this also has a disadvantage that it takes a lot of cost and time.

In order to prevent this, according to the present invention, as shown in FIG. 6, a casing 30 for a primary pile file for protecting the ground near the pile driving point is formed, and the inside of the casing 30 for the primary pile file (8A) with a shorter length, and then install it.

First, the casing 30 for the primary hitting file is mounted on the hovering target point, and then the primary hitting file 8A having a length short enough to be fixed to the casing 30 for the primary hitting pile is secured to the crane Into the casing 30 for the primary hunting pile and hover with the hunting equipment.

At this time, since the primary hitting file 8A is relatively short in length and is stuck in the inside of the casing 30 for primary hatching pile, a wave transmitted to the water surface is transmitted to the primary hatching casing 30), which is helpful for hunting, and it does not interfere with the adjacent ground in the lateral direction, so that fast and robust hunting becomes possible.

When the hammering operation is completed, the divided secondary water column 8B is bolted to the primary hammering pile 8A in the water.

When a plurality of secondary water column 8B is assembled upwards, the pile structure shown in Fig. 7 is completed.

In this state, if the both side ends of the secondary partition wall 16 are recessed into the secondary water film column 8B, the structure 1 shown in Fig. 7 is formed.

In this case, a girder or a strut (Strut) 14 is provided on both inner side walls of the water tray column 8B to more firmly support the frame. Particularly, it further strengthens the supporting force against hydrostatic pressure or hydrostatic force, which is a lateral pressure force.

The entire structure 1 is completed by assembling a separate corner partition 17 to the corner.

FIG. 8 is a front sectional view showing a sheet pile installation structure of a deep sea sink lifting method according to an embodiment of the present invention.

8 is a view showing a method of constructing the structure 1 by installing the sheet pile 10 and connecting the water receiving sheets 11 instead of installing the H file 8.

First, as shown in Fig. 1, the seat pile 10 suspended from a crane of a crane line 6 anchored to the water surface is settled to the surrounding seafloor of the sunken body 2. During the process of fixing the sheet pile 10 to the original ground 4 before sinking the sheet pile 10 to the surrounding seafloor 2, the sinking pile 2 is affected It is further necessary to fix the immersed body 2 to the ground.

8, a plurality of the sheet piles 10 are provided on the circular ground 4 so that the circular structure 1 is formed to be surrounded in the peripheral space of the sunken object 2, Install it.

In this state, the water receiving sheet 11 is provided on the sheet pile 10 to form the structure 1. [

In this case, unlike the case where a girder or a strut 14 is provided on both inner side walls of the H-file 8, drainage is not performed. Therefore, even if the structure 1 is not affected by water pressure, 14) to reinforce the structure.

This structure makes it possible to perform a safe operation quickly and economically because it is not influenced by algae when the deep sea diver works on the sunken body 2 by the water receiving sheet 11. [

FIG. 9 is a front sectional view showing an installation block of a deep sea sink lifting method according to an embodiment of the present invention.

9 is a view showing a state in which the car accommodating cellular block 20 is installed on the ground and the other car accommodating cellular block 20 is installed repeatedly thereon in place of the installation of the H file 8, It is possible to secure the same order space as that of installing the seat file 10 and connecting the water receiving sheets 11, respectively.

First, as shown in FIG. 1, the car-containing cellular block 20, which hangs on the crane of a crane line 6 anchored to the water surface, is settled to the surrounding seafloor of the sunken body 2. At this time, before the car-receiving cellular block 20 is settled to the surrounding seabed of the sunken object 2, the sunken object 2 is fixed to the original ground so that the sunken object 2 is not affected by other operations More steps are needed.

In this state, as shown in FIG. 9, a plurality of the car-receiving cellular blocks 20 are installed in the circular ground 4 so that the circular structure 1 is surrounded in the peripheral space of the sunken body 2 Respectively.

In this state, the structure 1 as shown in Fig. 9 can be constructed by repeatedly installing another car-receiving cellular block 20 above the car-receiving cellular block 20 and connecting it with the connecting pin 22 .

In this case, a girder and a strut (14) are provided on both inner side walls of the H-file (8) to cope with water pressure, and a large pump is operated in the water film structure to drain the water.

However, since this structure works under the same conditions as in the land in the inner space of the car-containing cellular block 20 or the structure of the car-receiving steel double wall, it does not receive any influence like a bird on the sunken ship It is possible to work quickly and safely, and is economically very advantageous. In addition, the method of forming the structure 1 by installing the car-accommodating cellular block 20 or the car-receiving steel material double wall is economically advantageous because the installation time of the structure 1 can be effectively reduced.
