Description

 Shore block to prevent earth and sand loss {REVETMENT BLOCK FOR PREVENTING EVACUATION OF SEDIMENT}

 The present invention relates to a protection block for earth and sand for protecting the surface of a lake by installing it on shore slopes, harbors, river shores, slopes, or underwater floors. Providing a smooth growth space, the plant provides a vegetation space so that it can be stably approached to the natural environment in a faster time, and provides a more stable shore slope by preventing coastal erosion or collapse of river banks due to soil loss. It relates to a protection block for soil loss.

Although various types of revetment blocks have been disclosed in the conventional patent literature in the art, existing revetment blocks are simply mounted on shore slopes, harbors, river rake slopes or underwater floors, and the soil is lost due to rapids and waves. Cases are frequently occurring, and as a result, they have failed to meet the functions of environmentally friendly protection block and have various problems.

Specifically, disclosed in Japanese Laid-Open Patent Publication No. Hei 11-107243, among the lanyard blocks in the art, does not have a configuration for connecting each lanyard block with another lanyard block, but only within the lanyard block. It is a form that has a configuration that allows the growth of plants by forming a cavity. This structure is not connected to each other is not necessarily connected to each other because of the flow or waves of the river inevitably can not maintain the state of construction when the gap between each block will not achieve the original purpose of construction As a result, the construction had to be reconstructed, which resulted in significant disadvantages in terms of effort and cost.

On the other hand, Japanese Unexamined Patent Publication No. 2002-105928, Japanese Unexamined Patent Publication No. 2003-090022, Korean Unexamined Patent Publication No. 2002-0020925, and Korean Unexamined Patent Publication No. 2003-0044558 supplement the above disadvantages. In order to connect each of the ban block to disclose a ban block is configured, but to connect each ban block with the other ban block was accompanied by the hassle of using a separate connecting member.

Also, among the conventional lanyard blocks, in the lanyard blocks disclosed in PCT International Publication WO 03/06040, PCT International Publication WO 03/066970, and Korean Laid-Open Patent Publication No. 2002-0010116, each lanyard block may be replaced with other lanyard blocks. Although the above-mentioned troublesome points are solved by constructing the interlocking blocks of each revetment block without using a separate connecting member to connect with each other, the relieving points of the relieving block described in the patent document are also described. The external force in the horizontal direction of the front, rear, left, and right of the block can be stabilized, but it has a disadvantage in that it does not have the ability to cope with the displacement of the foundation ground such as vertical external force, that is, uneven settlement after construction of the raft block.

As described above, the type having the interlocking structure between the revetment blocks also has a disadvantage in that it does not have the ability to respond to displacement of the foundation ground, such as uneven settlement after construction of the revetment block.

In addition, in the conventional revetment block as a measure to prevent the loss of the sediment deposited on the revetment block is merely to have a configuration that allows the growth of plants (that is, the same structure as the earth and sand loss prevention network of the present invention) Has the disadvantage of not being able to respond properly to high flow rates and waves.

In addition, in the case of constructing by using the above-mentioned revetment block, since it requires a separate equipment and process, the construction cost is high, the construction period is long, and many cases require reconstruction.

 The present invention is to solve the problems as described above, and has a structure for interlocking between the raft block in the raft block itself is configured to have a coping force to the displacement of the foundation ground, such as uneven settlement after construction of the raft block.
