The present invention relates to a pressurized stone drop for protecting an underwater structure, and more particularly, a pressurized stone for protecting an underwater structure to prevent breakage of an underwater structure caused by a dead stone when a dead stone is dropped on an underwater structure to protect the underwater structure. It is about the release.

As shown in Fig. 1, in the case of installing the underwater structure 1 (high voltage electric cable, etc.) in the water (river, sea), the pressed dead stone (S) is loaded on the barge (2), the fork-lane and so on The heavy equipment 3 is mounted, and the dead stone S is dropped in the water by the heavy equipment 3.

However, the push-seat dropping method according to the prior art has the following problems.

Since the dropping of the sandstone (S) is made in the water phase, there is a resistance by water, but the underwater structure (1) has a problem that the damage caused by the collision of the sandstone (S) occurs.

In addition, since the dropping of the dead stone (S) is made only by the dead weight of the dead stone (S), some of the dead stones (S) cannot be dropped on the underwater structure (1), and thus there is a problem in that the amount of use of the dead stone (S) increases.

In addition, there is a problem in that the use fee, labor costs, etc. caused by the use of a separate heavy equipment (3).

The present invention is to solve the above-mentioned conventional problems, to provide a push-down stone for protecting the underwater structure that can prevent the damage of the underwater structure caused by the dead stone when it is dropped on the underwater structure to protect the underwater structure. There is a purpose.

And, another object of the present invention is to be able to drop the sandstone only on the underwater structure.

Another object of the present invention is to reduce the cost by dedicating equipment for the dropping of the sandstone.

Pressed dead stone for protecting the underwater structure according to the present invention provided to achieve the above object, the barge is floating on the sea and the dead stone is loaded and provided with a discharge port; A dropping means comprising a plurality of actuators mounted on the barge and at least one dropping plate for pushing and dropping the dead stone loaded on the barge into the dropping port while moving forward and backward by the actuator; And a protective mat wound on the winding drum mounted on the barge and laid on the underwater structure embedded in the bottom of the water.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

As shown in Figures 2 and 3, the pressurized stone to protect the underwater structure according to the present invention, floating in the water and stored in the sandstone (S) and the barge (10) provided with the outlet 11, barge ( It is composed of a dropping means 20 mounted on the 10) and pushed the dead stone (S) to the discharge port 11, and a protective mat 30 mounted on the barge 10 and covering the underwater structure (1).

The barge 10 floats on the water and can be driven by a tug or by its own power, and the outlet 11 is preferably formed in the center of the barge 10.

The dropping means 20 is composed of a curved dropping plate 22 which pushes back and forth by the actuator 21 and the actuator 21 to push the dead stone S toward the dropping hole 11 side, and the dropping hole 11 It can be mounted in two places on both sides of. The dropping plate 22 is connected to one or more actuators 21. The actuator 21 may be a hydraulic cylinder or the like, and may be remotely controlled through a remote controller.

The protective mat 30 is wound on the winding drum 31 and laid on the underwater structure 1 while being released by the dead stone S laid upon the barge 10. In other words, if one end of the protection mat 30 is fixed to the sand structure (S) on the underwater structure (1), and then dropping the sand stone (S) while driving the barge 10, the sand stone (S) to the protection mat (30). Since the mat is fixed to the protective mat 30 is to be released.

That is, according to the present invention, since the dead stone (S) is not directly laid on the underwater structure (1) but on the protective mat (30), it is possible to prevent the scour of the underwater structure (1) and the like while preventing the damage of the underwater structure (1). You can do it.

On the other hand, the pressurized stone release for protecting the underwater structure according to the present invention, the dropping guide (40) may be further included in order to drop the dead stone (S) on the underwater structure (1).

Drop guide tube 40 is a plurality of pipes (41, 42, 43) of different diameters made of different diameters so as to drop the dead stone (S) on the underwater structure (1) irrespective of the water depth change (in the drawing Only three are shown), and elevators 44 that expand and contract the pipes 41, 42, 43. The pipes 41, 42, and 43 are provided with locking jaws 41a and 42a at the joints so that the pipes 41, 42 and 43 are not separated from each other. The elevator 44 is wound around the winding drum 44a and the winding drum 44a. It may be composed of a motor (not shown) winding the wire 44b and the winding drum 44a connected to the pipe 43. The wire 44b is preferably a chain which is not broken by the dead stone (S), and may be disposed outside the pipes (41, 42, 43).

The action of the pressurized stone to protect the underwater structure according to the present invention configured as described above is as follows.

After loading the dead stone (S) on the barge 10, and moves to the installation place of the underwater structure (1).

After digging out a groove on the bottom of the water and putting the underwater structure (1) in the groove and then backfilling to install the underwater structure (1), the length of the drop guide tube 40 is adjusted according to the depth. How to adjust the length of the drop guide pipe 40 is slowly descended from the third tube (43) of the lowermost when the elevator 44 is released, the second tube 42 is lowered when the lowering of the third tube (43) is completed. The length of the overall drop guide tube 40 can be adjusted to the depth.

When the length adjustment of the drop guide tube 40 is completed, one end of the protective mat 30 is fixed to one side of the underwater structure (1) by the sandstone (S), and then along the longitudinal direction of the underwater structure (1) When the barge 10 is moved, the protection mat 30 is laid on the underwater structure 1 while being slowly released from the winding drum 31.

When driving the actuator 21 of the dropping means 20 while laying the protective mat 30, the dropping plate 22 advances and pushes the dead stone S into the dropping hole 11 so that the dead stone S is discharged. Through the drop guide tube 40 through the inside, the dead stone (S) is dropped on the protective mat 30 through the drop guide tube 40, pressing the underwater structure (1) with the protective mat 30 in between. This prevents scour and the like of the underwater structure 1.

As described above, according to the pressurized stone drop for protecting the underwater structure according to the present invention, by dropping through the protective mat instead of directly dropping the supporting stone so that the underwater structure is not scoured over the underwater structure through the impact of the dead stone It can prevent the damage of the structure.

In addition, since the dead stones are dropped only on the underwater structure through the drop guide, the loss of the dead stones can be reduced, thereby reducing the use of the dead stones, thereby reducing the cost.

In addition, since the equipment for dropping of the dead stone is mounted on the barge exclusively, it is possible to automatically drop the dead stone without mounting unnecessary heavy equipment, thereby reducing costs.

While the invention has been described and illustrated in connection with a preferred embodiment for illustrating the principles of the invention, the invention is not limited to the configuration and operation as such is shown and described. Rather, it will be apparent to those skilled in the art that many changes and modifications to the present invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes and modifications and equivalents should be considered to be within the scope of the present invention.
