Description

Dredging apparatus having flexible pipe

The present invention relates to a dredging device having a flexible pipe, and more particularly, to a dredging device for dredging sludge, soil, sand, gravel and the like (hereinafter referred to as 'tosa') of lakes, rivers, seas, and the like. .

Dredging is carried out to achieve various purposes. Typically, dredging is carried out to remove contaminants deposited on the water surface, and dredging is also performed to collect aggregate from the water surface.

Dredging in small places, such as artificial ponds, is made relatively easy by a wide variety of devices and methods.

On the other hand, dredgers are mainly carried out by floating dredgers in relatively large lakes, rivers and seas.

If you look at the configuration of a dredging device to float dredger, a dredger having various mechanical devices, such as a pump for suction and discharge of the soil, suction pipe extending from the dredger to the bottom of the dredger, is installed extending from the dredger to the ground It includes a discharge pipe. In addition, the dredger may be provided with a shredding device extending to the water surface. Depending on the configuration of the device, the suction pipe and the shredding device may be connected to a crane installed in the dredger to be controlled on the dredger.

The method of dredging using the above apparatus will be briefly described as follows. First, float the dredger, and move the dredger to the position to be dredged. Next, the suction pipe is placed on the bottom of the water and the soil is sucked through the suction pipe by driving a mechanical device such as a pump located on the dredger. Next, the sucked soil is discharged to the ground through the discharge pipe. In case of inhalation, the water is sucked together with the earth and sand, and the water is separated and discharged on the dredger, and only the soil is transported to the ground.

In the conventional dredging device as described above, the suction pipe and the discharge pipe mainly consist of a metal pipe. If the suction and discharge pipes consist of metal pipes, the suction and discharge pipes should only be installed in a straight line due to the nature of the metal pipes. In this case, there is a problem in that the pipe must be newly connected every time the dredger moves.

In order to improve the above problems, the suction pipe and the discharge pipe are formed of a metal pipe, but may be used by connecting a flexible rubber pipe to a predetermined portion. In this case, however, the cross section of the pipeline through which the soil is transported is uneven, which causes severe flow resistance, and thus causes overload of a mechanical device such as a pump. In severe cases, the suction and discharge pipes may be temporarily blocked, which may occur when the pipe flows due to movement or dredging of the dredger, while the rubber pipe part connected to the metal pipe is temporarily folded. In addition, the metal tube and the rubber tube is connected by the flange coupling, it takes a lot of cost and time for the connection, there is also a problem in durability due to the relative weakness of the rubber tube portion.

The present invention has been made in order to solve the above problems, by using at least one of the inlet pipe and the discharge pipe as a flexible material, even if the pipe flows due to the movement of dredgers, waves, etc., the pipe dents, blockage of the pipe It is an object of the present invention to provide a dredging device capable of stably inhaling and discharging soil without occurrence of this.

Still another object of the present invention is to form a suction pipe and a discharge pipe by using a material which ensures safety and ease of construction by numerous repeated constructions, thereby improving durability of the suction pipe and the discharge pipe, and facilitating the construction and handling of the suction pipe and the discharge pipe. It's about letting go.

The present invention provides a dredging device having a flexible pipe, the dredging device according to the present invention, the dredger is equipped with a mechanical device including a pump for suction and discharge of the soil; A suction pipe extending from the dredger to the bottom of the water and sucking the soil; And a discharge pipe extending from the dredger to the ground to discharge the earth and sand, wherein at least one of the suction pipe and the discharge pipe is characterized in that the main material of the pipe is flexible.

At least one of the suction pipe and the discharge pipe made of the flexible material is characterized in that the synthetic resin pipe.

It is preferable that the said synthetic resin pipe is made from polyethylene.

According to the present invention as described above, by using at least one pipeline from the suction pipe and the discharge pipe as a flexible material, even if the pipeline flows due to the movement of dredgers, waves, etc., no crushing of the pipeline, blockage of the pipeline does not occur The soil can be sucked in and discharged stably.

In addition, by forming a suction pipe and a discharge pipe by using a synthetic resin pipe (polyethylene pipe), which has secured safety and ease of construction by numerous repeated constructions, it improves the durability of the suction pipe and the discharge pipe, and facilitates the construction and handling of the suction pipe and the discharge pipe, unlike in the related art. can do.

1 is a conceptual diagram illustrating a dredging device according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, a dredging device according to an embodiment of the present invention will be described in detail.

In describing the present invention, the size or shape of the components shown in the drawings may be exaggerated or simplified for clarity and convenience of description. In addition, terms that are specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator. These terms are to be construed in accordance with the meaning and concept consistent with the technical idea of the present invention based on the contents throughout the present specification.

As shown, the dredging device according to an embodiment of the present invention is a dredger 10, a suction pipe 20 extending from the dredger 10 to the bottom surface of the dredger 10 and the discharge pipe 30 extending from the dredger 10 to the ground; Include.

Although not shown, the dredger 10 includes a pump for suction and discharge of the earth and sand, various machinery and control devices for sailing, and the like. In addition, a crane 11 may be installed from one end of the dredger 10, and a shredding device 12 may be connected to an end of the crane 11. The suction pipe 20 part in contact with the bottom surface may also be connected to the crane 11 and controlled from the dredger 10.

In the embodiment of the present invention, at least one of the suction pipe 20 and the discharge pipe 30 is made of a flexible material. When the suction pipe 20 and the discharge pipe 30 are made of a flexible material as described above, even if the pipe path is changed or the pipe flows due to the movement of the dredger 10 or the wave, the pipe is crushed or blocked. This does not occur, so it is possible to stably suck and discharge soil.

The suction pipe 20 and the discharge pipe 30 made of the flexible material is preferably formed of a synthetic resin pipe. Synthetic resin pipe is flexible due to the unique properties of the synthetic resin, and is suitable as the suction pipe 20 and the discharge pipe 30 when considering the problems caused by the movement of the dredger 10, the influence of waves.

In particular, it is preferable that the suction pipe 20 and the discharge pipe 30 are formed of polyetherene pipe, and the polyethylene pipe is excellent in long-term durability due to numerous repeated constructions and uses, and has been proved to be easy to construct. When the suction pipe 20 and the discharge pipe 30 according to the embodiment of the present invention is formed of a polyethylene pipe, it is possible to completely improve the conventional problem that the pipeline is crushed or blocked due to the movement of the dredger 10, the influence of waves, etc. Can be.

In addition, the polyethylene pipe has a certain slip property (slip) due to its peculiar property, which makes it easier to transfer the soil which is sucked and discharged through the suction pipe 20 and the discharge pipe 30 formed of the polyethylene pipe. Is done.

In the dredging process, when the soil is collected from the deeper water surface, or when the dredger 10 moves and collects the soil from an area farther from the land, the suction pipe 20 or the discharge pipe 30 should be extended. In such a case, when using the suction pipe 20 and the discharge pipe 30 connected to the metal pipe or the metal pipe in a predetermined length as in the prior art, it is very troublesome and expensive to extend the pipe line. When the suction pipe 20 and the discharge pipe 30 is a polyethylene pipe, the extension of the suction pipe 20 and the discharge pipe 30 can also be very easy. For example, if the suction pipe 20 is to be extended, the suction pipe 20 connected to the pump can be separated and easily extended using a flange for polyethylene pipe secured by ease of construction by butt fusion or repeated use by a desired length. In addition, in the case of extending the discharge pipe 30 can be extended in the same manner as the suction pipe 20, in this case, it is possible to extend the length more easily by performing butt fusion in the ground.

When the suction pipe 20 and the discharge pipe 30 (especially the discharge pipe) is used to connect the rubber pipe to the metal pipe and the metal pipe at a certain length, the specific gravity of the pipe line is largely sinking to the water surface. When the pipeline sinks to the surface as a whole, the overall length of the discharge pipe 30 should be long, which inevitably increases the cost and difficulty of handling. However, when the suction pipe 20 and the discharge pipe 30 (particularly the discharge pipe) is a polyethylene pipe, the discharge pipe 30 is exposed to the water surface because the specific gravity of the polyethylene is smaller than the water. In this case, the length of the entire pipe line may be shorter than that of the metal pipe, which leads to cost reduction. In addition, due to the floating in the water pipe can be easily confirmed, such as damage to the discharge pipe 30, it is easy to handle.

When the suction pipe 20 and the discharge pipe 30 are made of metal pipes as in the related art, a phenomenon in which the pipe line is crushed or blocked occurs, and the overall length of the pipe line becomes long, which inevitably causes an overload of a mechanical device such as a pump. In addition, repeated overloading of machinery results in shortening its lifespan. In addition, large capacity of machinery such as pumps should be designed in consideration of pipe distortion, blockage, length of pipeline. On the other hand, when the suction pipe 20, the discharge pipe 30 is formed of polyethylene pipe as in the present invention, the pipe line is not crushed or blocked, and the length of the pipe is relatively short, so that the overload of the mechanical device can be prevented. The overall cost can be reduced by not having to design a large capacity of machinery, such as a pump.

Although the present invention has been described with reference to the above-described preferred embodiments and the accompanying drawings, different embodiments may be constructed within the spirit and scope of the invention. Accordingly, the scope of the present invention is defined by the appended claims, and is not to be construed as limited to the specific embodiments described herein.
