Description

[Detailed description of the invention] This invention relates to a connected concrete block for revetment used on the slopes of river banks, etc. As shown in the figure, the front wall of the block body 1 made of concrete is shaped like a rectangular parallelepiped. A concave part 2 and a convex part 3 that can be fitted into the concave part 2 and the rear wall are formed, and a protrusion 4 is provided in the center of the upper surface with an inclination around the four circumferences, and a protrusion 4 is provided in the upper half of the entire outer circumferential wall. It has a structure in which an inclined surface a is attached and through holes 5, 5.5 communicating from the front to the rear are provided in the center of the main body.

Since the present application has the above-described structure, the front and rear bulges and convex portions 3 and concave portions 2 are fitted into each other and are tightly connected in series, as shown in FIG. 5, and a wire or reinforcing bar is inserted into the through hole 5. If connected together, it will fit well and adhere well to the sloped ground surface or curved surface, preventing soil and sand from flowing out.

The device-like protrusions 4 on the surface are extremely useful for moderating the flow velocity.

Furthermore, in this application, the parallel combination can be varied in various ways,
For example, as shown in Fig. 6, the connected state in which they are arranged horizontally in the same direction may be arranged in reverse rows every other row, with the concave portions facing each other, butt against each other, and arranged in a staggered manner with spaces arranged, or as shown in Fig. 7. It is also possible to create several rows in opposite directions, with rows in the same direction every other row, shifted by half a length each.

In other words, the interlocking of the concave and convex portions of each block ensures a tight connection and greatly increases the stability of the revetment.Moreover, it conforms well to the curved surface of the slope, and the protrusions reduce the flow velocity, and the interlocking of the blocks simplifies the installation work on site. No particular skill is required for construction, construction management is easy, and the block has three through holes for reinforcing bars, allowing you to decide the number of reinforcing bars to be used as needed for areas such as rapids, water bumps, and curved areas. The blocks are extremely flexible, and even after the blocks are laid, it is easy to insert reinforcing bars into them, and there is no need for horizontally connecting reinforcing bars like in conventional blocks, which significantly improves on-site work efficiency.

Furthermore, since there are no straight joints in the direction of water flow, the phenomenon of suction of earth and sand can be reduced.

Furthermore, there are few gaps between the bending blocks at the top and apron.
It has a great erosion prevention effect, and by mixing blocks in a combination arrangement, construction can be done in 5cm increments.The gaps created by the staggered arrangement can be filled with planting methods, creating a landscape that is adapted to the environment. It is possible to create new designs, reduce construction costs by 20%, and the shape of the block is novel and the surface finish is beautiful, creating a geometric pattern.
It can be used for a variety of purposes, such as protection work for the outer high water bed of bank revetment work, and bed protection work.

As described above, according to the present application, the interlocking of the blocks ensures a close connection, it is stable by adapting to the curved surface of the slope, it is effective in moderating the flow velocity, it is easy to construct, and the finished surface is beautiful.
