Description

Circular block for revetment

The present invention relates to a circular revetment block, which forms a circular main body having a desired thickness, and forms a fixing groove that is inwardly drilled at an edge of the main body, and a plurality of the fixing grooves are formed along the circumference of the main body. , Part of which is embedded inside the main body, and part of the elongated block comprising a circular ring-shaped fixing bar that is maintained to be exposed to the outside to cross the fixing groove, the overall planar shape due to the disk-like By constructing the rake block forming the same shape symmetrical to each other,

By applying this revetment block to the revetment construction of rivers, beaches, and other slopes, by connecting the fixing bars facing each other of the adjacent revetment blocks with fixing means, the adjacent revetment blocks are installed to be fixed in close contact with each other. , Assembly with adjacent shore bank blocks. When connected in any direction, the same surface contact and the same spacing are maintained, so that it is possible to install between adjacent neighboring revetment blocks regardless of the installed direction, and it is formed in a disk shape as a whole. The block prevents the scouring of the slope, and the construction can be performed in various forms such as curved shapes or curved surfaces corresponding to the shape of the ground, even under the terrain imbalance of the construction site.

In addition, in the manufacturing process of the revetment block of the present invention, the revetment block is a disk-shaped structure, formed into a structure in which the protrusions of the center portion and the radial protrusions are arranged around the center, thereby the imbalance of compaction due to the introduction of mortar during the molding process. It is not easy to produce and demould homogeneously molded products with uniform compaction, and can produce products regardless of the orientation of the mold (installation position). It has a structure that can uniformly distribute the impact and pressure caused by the external force by the structure.

In general, a lake is a slope where water is generally encountered in rivers, coasts, and embankments. A lake block is installed on these slopes to erode and scour soils due to runoff. Refers to the civil engineering structure installed on the slope to prevent the damage. Representative structure applied to the slope is a revetment block, which is manufactured in the form of a block and installed on the coast, river, and other slopes to protect the slope and scour. It is used for the purpose of preventing.

In addition, such a raft block is mainly made of a polygon, such as a square, or is made of a circular, first, look at the example of manufacturing a square, domestic utility model registration No. 076258 in the shape of a cube, a number of holes therein It is formed so as to penetrate, and each of the four sides is formed with a vegetation revetment block having a structure formed with a coupling protrusion and a fixed groove, the two neighboring vegetation revetment block is posted about the taegeuk vegetation revetment block is constructed to be joined by the coupling protrusion and the fixed groove have.

And look at the example that the revetment block is manufactured in a circular, domestic utility model registration No. 0338773 constitutes a vegetation revetment block forming four fixing grooves and coupling protrusions along the edge of the block body of a circular shape having a predetermined thickness In addition, the contents of the vegetation revetment block is constructed so that the two neighboring vegetation revetment block is joined by the fixing groove and the engaging protrusion, and published in Korea Patent Publication No. 2008-0109209 protrudes on the outer shape of the ring-shaped outer circular body and its outer circular body A prefabricated circular revetment block is constructed in which a prefabricated ring is integrated, and a prefabricated circular revetment block is constructed to fasten a neighboring revetment block through a loop.

However, in the case of the first example of the taegeuk vegetation raft block, the overall shape of the raft block has a hexahedron, that is, a rectangular structure, so if the bottom is uneven or the bottom is flat, the floor is flat. Since it is necessary to clean up, there is a disadvantage in that the air is long, and since the installed revetment blocks are in contact with each other, if the installation surface itself is not flat, it is difficult to select the surface of the revetment installed relieves, and there is a concern that the construction will be protruded at the edges or protruding. The rectangular revetment block had a problem that, after installation, was easily damaged when subjected to an external force on the edges, corners, and other sides of the core.

In the case of the first and second examples of the taegean vegetation raft block and the vegetation raft block, the two neighboring raft blocks have a corresponding structure of grooves and protrusions, that is, a combination of a fixed groove and a coupling protrusion (interlocking method). Since the joints, which are adjacent to each other during installation, must have accurate groove and protruding points, they require a skilled raft block assembly hole for installation, a long construction time, and a free-form coupling structure. After construction, there is a problem that frequent defects such as separation and loss due to external force occur, and there is a problem that the construction site needs to be cleaned up when the bottom of the construction site of the raft block is not flat.

In addition, depending on the construction site to which the interlocking revetment block is applied, the geographic characteristics of the construction site, for example, the topographical characteristics of the conical slope, or the sloped surface where the bottom of the slope is different from the curved slope to the upper and lower construction areas As it is difficult to match the connection points between adjacent blocks that are constructed due to the characteristics of the terrain that is gradually narrowed toward the upper part of the construction site (the lower part is wider and the upper part is narrower), the upper part is densely constructed, Construct them with a slight gap between each other (spacing the space between the revetment blocks), and install them by filling a space in the space between them, or by separately filling the space between the adjacent revetment blocks. In the case of the construction such as to insert a small revetment block The difficulty is to follow, and also have had the problem that can not be reflected at all the very nature of their construction fingers terrain.

In addition, in the case of the prefabricated circular revetment block exemplified by the third example, the distribution of force in the form of a circle is easier than the square, and the installation of the non-flat place by the fastening of the adjacent revetment block by the loop is easy, but protruding Since there is a fastening structure by the structure of the loop, the space between the neighboring shore blocks according to the projecting degree of the protruding ring and the coupling means to be used is generated. Since the space between the lanyard blocks is increased, the effect of the slope protection is inferior, and if the number of rings is large, there is a problem that neighboring lanyard blocks are damaged by the loop in the storage, moving and installation state.

Therefore, in order to solve the above problem, the present invention forms a circular main body having a required thickness, and forms a fixing groove that is drilled inward at an edge of the main body, and a plurality of the fixing grooves are formed along the circumference of the main body. And part of which is embedded in the main body, and part of which is composed of a revetment block including a circular ring-shaped fixing bar which is kept exposed to the outside so as to cross the fixing groove, which is generally flat due to the shape of a disk. By constructing a bank block in the same direction symmetrical with each other,

By applying this revetment block to the revetment construction of rivers, beaches, and other slopes, by connecting the fixing bars facing each other of the adjacent revetment blocks with fixing means, the adjacent revetment blocks are installed to be fixed in close contact with each other. Since the same surface contact and the same distance are maintained even when installed in any direction when assembling and connecting with the adjacent banks, the construction is possible between the neighboring banks of the neighboring banks regardless of the installed direction. As a result, the circular revetment blocks are densely constructed from each other to prevent scouring of the slopes, and the construction can be performed in various forms such as curved shapes or curved surfaces corresponding to the shape of the ground, even under the unbalanced conditions of the construction site.

In addition, the fixed bar applied to the present invention maintains a circular ring shape that crosses the circumferential direction of the main body, and a part of the fixed bar maintains a form embedded in the main body, and is exposed to the outside at the position where the fixed groove is located. The circular ring-shaped fixing bar serves as a reinforcing bar (reinforcing barn) to reinforce the rigidity of the revetment block, and at the same time serves as a fixing bar (support) for fixing the fixing means to be described later. At the same time, the ring-shaped fixed bar is provided with a “Y” shaped reinforcement bar, which extends in a radial direction to have an angle of 120 ° from the inner center point of the fixed bar. In addition to reinforcing the rigidity of the ring-shaped fixing bar, the reinforcing bar is integrally embedded in the main body of the revetment block, thereby simultaneously reinforcing the strength of the manufactured revetment block. To do that.

In addition, in the manufacturing process of the revetment block, by forming a disc-shaped structure, the imbalance of compaction due to the injection of mortar does not occur during the molding process, it is not only easy to produce and demould a homogeneous molded product having a uniform compaction degree In particular, the product can be produced regardless of the orientation (installation position) of the mold, and the produced circular revetment block has a basic circular structure to uniformly distribute impact and pressure caused by external force.

Therefore, the present invention forms a circular main body having a required thickness, and forms a plurality of fixing grooves inwardly formed at the edges of the main body, and a plurality of the fixing grooves are formed along the circumference of the main body, and part of the main body is inside the main body. Which is embedded in and partially composed of a raft block comprising a circular ring-shaped anchoring bar which remains exposed to the outside to cross the anchoring groove, which is generally symmetrical to each other in any planar direction due to the disk-like shape as a whole. By constructing the rake block forming the shape,

By applying this revetment block to the revetment construction of rivers, beaches, and other slopes, by connecting the fixing bars facing each other of the adjacent revetment blocks with fixing means, the adjacent revetment blocks are installed to be fixed in close contact with each other. Since the same surface contact and the same distance are maintained even when installed in any direction when assembling and connecting with the adjacent banks, the construction is possible between the neighboring banks of the neighboring banks regardless of the installed direction. In addition, it is possible to prevent the scouring of the slope by the circular revetment blocks that are tightly constructed with each other, as well as to be applied in various forms such as curved shapes or curved surfaces corresponding to the shape of the ground, even under the terrain imbalance conditions of the construction site. .

In addition, the fixed bar to be applied to the present invention is composed of a circular ring-shaped fixed bar transverse to the circumferential direction of the main body, the "Y" shaped to extend radially to have an angle of 120 ° from the inner center of the fixed bar As the reinforcing bar is provided to be integrated, a part of the fixing bar and the reinforcing bar are embedded in the main body, and a part of the fixing bar is maintained to be exposed to the outside at the position where the fixing bar is located. The fixing bar and reinforcing bar of the shape serves as a reinforcing bar (reinforcing bar) to reinforce the rigidity of the revetment block, the exposed portion of the fixing bar serves as a fixing bar (support) for fixing the fixing means described later. At the same time it is effective.

In addition, in the manufacturing process of the raft block, the present invention is molded into a disc-shaped structure, so that the imbalance of compaction due to the mortar input during the molding process does not occur, so that the production and demoulding of a homogeneous molded product having a uniform compaction degree is easy. In addition, in particular, the product can be produced regardless of the orientation of the mold (installation position), and the produced circular revetment block has the effect of uniformly distributing impact and pressure caused by external force by the basic circular structure.
