Description

Shore protection block

The present invention relates to a raft block, and more particularly, to a raft block which is installed in a riverside, a beach, etc. to prevent erosion of soil by flow and provide a foundation for planting various plants. will be.

In general, river banks and river banks are erected by rivers, where earth and sand are likely to be lost. In recent years, with increasing interest in the environment of rivers, they are setting up lakes in consideration of environmental requirements as well as dimensional requirements, which are called (1) hydrophilic / river use banks, (2) ecosystem preservation banks, (3) It can be classified as landscape preservation draft. As such, the revetment method using natural stone has advantages in that it can have an eco-friendly appearance while considering the ecological function of the river, but the construction cost is expensive, and natural stones are not firmly combined with each other and will be lost when the flow velocity increases. Not only is there a concern, there is a disadvantage in that the vegetation base of the plant cannot be provided uniformly.

In order to make up for such drawbacks, it is known to perform a revetment construction using concrete structures having various structures capable of forming voids that are based on vegetation. For example, in the Republic of Korea Patent Publication No. 2001-48066, as shown in Figure 1, the surface portion 10 has a plate-shaped hexahedral structure formed with a plurality of projections 12, each side has a semi-circular groove 14 An arc block is formed, each of which is formed with a quarter circular groove 16 formed at each corner. Each revetment block is connected to each other in a plate shape, so that the semicircular grooves 14 on each side and the quarter circular grooves 16 on each corner are formed to form a circular groove 18 on which the vegetation is based. However, since the raft block or raft structure disclosed in the above-described Korean Patent Publication No. 2001-48066 is disposed in parallel with the ground, it has a strong structure against the pressure applied in the horizontal direction to the ground, but is very vulnerable to the pressure acting perpendicularly to the ground. In addition, the bonding force between the raft block is not secured. Therefore, when the intensity of the flowing water is increased or the waves are drastically driven, there is a high possibility that a problem arises in that the shore block or the shore structure collapses and the soil which is located below is lost.

Accordingly, it is an object of the present invention to provide a raft block that can provide the vegetation base of the plant while protecting the underlying structure of the dike.

Another object of the present invention is to provide a raft block which is less likely to be broken or disassembled even when pressure is applied horizontally and / or vertically.

Another object of the present invention is to provide a raft block having a relatively simple structure.

Figure 2 is a perspective view of the revetment block according to an embodiment of the present invention.

Figure 3 is an exploded perspective view of the revetment block according to an embodiment of the present invention shown in FIG.

In order to achieve the above object, the present invention has a core material having a hexahedral shape; And tapered protrusions protruding from the six surfaces of the core member, respectively. Here, the rake block includes a front, side and rear projections protruding from the front, side and rear of the central portion having a hexahedral shape, the central portion is coupled to the side projections as a whole, and partially coupled to the front and rear projections. It is preferable that the first member made of a rectangular parallelepiped first center member and the second member having the same shape as the first member are vertically coupled to each other such that the respective center members abut each other.

Hereinafter, with reference to the accompanying drawings will be described in detail the relief block according to an embodiment of the present invention as follows.

Figure 2 is a perspective view of the revetment block according to an embodiment of the present invention, as shown in Figure 2, the revetment block according to an embodiment of the present invention is the core member 50 and the central member having a hexahedral shape ( And tapered protrusions 52, 54, 56, 60, 62, and 64, respectively, protruding from six faces of 50). Each of the protrusions 52, 54, 56, 60, 62, and 64 of the revetment block has a taper shape in which the thickness thereof becomes thicker toward the center member 50. Each of the protrusions 52, 54, 56, and 60 has a taper shape. , 62, 64 of the tapered degree of each of the protrusions 52, 54, 56, 60, 62, 64 can be firmly coupled to the central material 50, the projections 52, 54 opposite the central material 50 56, 60, 62, 64) is set to have a thickness such that the end is not broken during transportation or construction of the relief eye member.

The taper degree which can achieve such a function is the protrusions 52, 54, 56, 60, 62, in which the cross-sectional area A at the ends of the protrusions 52, 54, 56, 60, 62, 64 is in contact with the central member 50. , 64) of 20 to 80%, preferably 40 to 60% of the cross-sectional area (B). If the cross-sectional area A of the protruding end is less than 20% of the cross-sectional area B of the protruding portion abutting with the central member 50, the distal end of the protruding portion is too thin and easily broken, and if it exceeds 80%, the protruding portions 52, 54 , 56, 60, 62, 64 is excessively thick, or the protrusions 52, 54, 56, 60, 62, 64 and the central member 50 is not firmly coupled.

FIG. 3 is an exploded perspective view of the revetment block shown in FIG. 2, and as shown in FIG. 3, the first and second members 500 and 600 having the same shape may be provided in the revetment block according to the embodiment of the present invention. It is made by combining vertically with each other. The first member 500 constituting the revetment block of the present invention includes a front, right and rear projections 52, 54 and 56 protruding from the front, right and rear surfaces of the central portion C having a hexahedral shape, respectively. The central portion (C) is composed of the first center member 58 on the rectangular parallelepiped to be coupled to the right side protrusion 54 as a whole, and partially coupled to the front and rear protrusions 52, 56, the second member 600 Has the same shape as the first member 500, and consists of the flat, left and bottom projections 60, 62, 64 and the second central member 68.

Here, the first center member 58 is partially coupled to the front and rear protrusions 52 and 56 to open the right side surface of the center portion C to a predetermined depth p. The depth p at which the right side surface of C) is opened is such that the front and rear protrusions 52 and 56 are separated from the first center member 58 before and after the transportation, coupling process and construction of the revetment block of the first member 500. It should be formed to such a depth that it will not be separated or broken. In this case, when the depth p of the first center member 58 is increased, the depth q of the second center member 68 may be decreased, and either of the opening depths p and q may increase. When is excessively large, since the center member and the projection of the member having the larger opening depth are more likely to be broken apart, the opening depths p and q are equal to each other, that is, the first center of the front and rear projections 52, 56. It is preferable that 1/2 of the cross section of the member side is engaged with the first center member 58.

When the first and second members 500 and 600 are vertically coupled to each other, the first and second central members 58 and 68 come into contact with each other by passing through the openings of the mating members, and thus the first center. The member 58 is supported by the planar and bottom projections 60, 64 of the second member 68, and the second central member 68 is the front and rear projections 52, 56 of the first member 58. It is supported by and forms a relief member as shown in FIG.

The revetment block according to an embodiment of the present invention can be completed by forming and fabricating the first and second members 500 and 600 by concrete, etc., and the size of such relieving block is used by the revetment block. It may be appropriately modified depending on the intended use. For example, it can be used to have a size of about 30cm to prevent the loss of coastal soils of small rivers, and can be manufactured to a size of about 1m to prevent the outflow of soils of large rivers or bottoms. . When the raft block according to an embodiment of the present invention manufactured as described above is positioned so that the protrusions of the rivers, the bottom, the beach, etc. of the rivers alternate, and fill the soil in the gap between the protrusions, sowing, Since the raft block binds more strongly by the root of the plant grown in the vegetation soil of the protrusion gap, it can have a strong raft structure capable of withstanding both the horizontal and vertical impact.

As described above, the raft block according to the present invention can not only provide the vegetation base of the plant while protecting the base structure of the embankment, but also less likely to be broken or dismantled even when pressure is applied horizontally and / or vertically. Compared to the shoreline block shown in the related art, the structure has a relatively simple structure.
