Sliding guider for sea riprap drop}

The present invention relates to a sliding guide for offshore sandstone dropping to facilitate the offshore sandblasting using a breakwater.

In order to construct port facilities such as breakwaters, seawalls, and spinning agents, sandstones are laid on the bottom of the sea floor.

Conventionally, a technique for constructing a sandstone was performed by loading a sandstone on a barge and dropping it directly into a fork lane or a crane or dropping it into a construction position using a tubular body.

According to the conventional utility model No. 20-0305867 for the prior art for dropping such a sandstone, to form a chain ring in the cylindrical steel drum and to connect a plurality of chains to the chain ring to manufacture a cylindrical chain ring network It is possible to drop the dead stone at the correct point while adjusting the length according to the depth of the water, and to prevent the wasted waste of the dead stone as much as possible, and to drop the pressed stone at the exact position where the submarine cable and the communication pipe are buried. We have disclosed a technology for deep-sea bottom pipe protection using a barge and a cylindrical chain loop to complete the work under the influence of the outside, thereby preventing the waste of the budget thoroughly.

According to Korean Patent Publication No. 10-0781032, the chute in multiple stages to increase the diameter toward the bottom so that the droppings such as sand or gravel can be dropped smoothly, and at the same time the chute receiving groove is provided at the bottom of the barge In the case of the end of the dropping operation and the like has been disclosed a technique for a submarine construction barge provided with a chute with an improved structure so that the chute can be conveniently mounted on the barge to move.

According to Korean Patent Publication No. 10-1678336, it is possible to adjust the length of the sandstone injection pipe assembly in response to the depth of the seabed depth so that there is little loss during construction, and the ground collision is prevented in the rock or shallow water section during the evacuation. The present invention discloses a technology for a sand-seat discharging device and a control method thereof for preventing a subsurface ground collision and a loss of sand of a barge.

As in the prior art, the sea work by the barge has a disadvantage in that the work efficiency decreases due to a lot of limitations depending on weather conditions. In other words, in case of bad weather, there is a problem of having to withdraw and re-introduce the equipment, as well as a loss of manpower and equipment rental costs, resulting in an uneconomic problem.

Particularly, when the dead stone dropping work is carried out in the existing breakwater section, the work efficiency is deteriorated due to the reflection wave caused by the breakwater, and there is a problem of a safety accident due to excessive work progress.
