Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a concrete frame block used for slope protection work.

(Prior art) As a slope protection work, bar-shaped or open-channel slope blocks are combined and joined in a lattice or tortoise-shell shape, and concrete is applied to the slope surrounded by the slope blocks, that is, the filler surface. The soil is filled with chestnut stone, crushed stone, etc. and compacted, or the surface of the soil is planted with grass or other vegetation for greening.

(Problems to be solved by the invention) When using rod-shaped slope blocks, the filling surface is irregularly eroded or washed away by rainwater, and when using an open channel type, the concave waterway area is prone to dirt, debris, etc. When empty cans accumulate, surface water concentrates in that area and overflows, and the water force often erodes or scours the filling surface, leading to destruction.

(Means for Solving the Problem) In a legal frame block formed by bulging both end sides of a square rod sideways into a mountain-shaped cross section to form a joint, a groove is formed on the top surface of the block. The above-mentioned problem is solved by providing a concrete manufacturing frame block having a hole formed therein to form a water channel therein, and a lid receiving stepped portion provided at the upper end of both end faces of the block.

(Operations and Examples) Examples of the present invention will be described with reference to the drawings.

As shown in Figures 1 to 4, isosceles triangular prism-shaped joints 1, 1... with right angle apex angles are formed on both ends of the square rod, and surface water is poured onto the top surface of the block. A groove 2 having an arcuate cross section is provided for water to flow down, recesses 3 are provided at the lower part of the side surface in the axial direction of the square bar for hanging a lifting fitting (not shown), and a water channel 4 is formed inside the recess. The block is formed into a rectangular tube shape by passing a circular hole in the axial direction, and furthermore, on the abutting end surfaces 5 at both ends of the rectangular tube body, a lid receiving stepped portion 9 is provided at the upper end, and a grooved groove is provided at the lower portion. 6 and 6 are respectively provided to form a concrete manufacturing frame block.
Note that 7 is a reinforcing bar for connecting the blocks to each other.

As shown in FIGS. 5, 6, and 7, the concrete frame blocks formed in this way are butted against each other in an X-shape or Y-shape, and one side of each joint 1 is placed in contact with each other. By tightening the contact reinforcing bars 7, a void is formed by the abutting end surfaces 5, 5, . . . of each concrete frame block. Then, a curing agent is filled in the space below the inner bottom surface of the water channel 4, and the space is converted into a water collection basin 8.
A water collection basin cover 10 is fitted into a cover receiving step 9 formed at the upper end of the abutting end face 5.

At this time, each concrete manufacturing frame block is integrated by the binding force of the reinforcing bars 7 and the hardening agent fitted into the grooves 6. In addition, the recess 3...
Filling materials such as concrete, chestnut stone, and crushed stone are inserted into the structure to integrate it.

The concrete manufacturing method frame block related to this invention is
When joined in a shape of a letter or Y, rainwater that falls on the spaced surface surrounded by each concrete frame block flows into the concave groove 2 on the top surface of the block and flows down into the catchment box cover 10. It falls into the water collection basin 8 after passing through the water. After the water is once collected in the water collection basin 8, it flows into the waterway 4 of the concrete frame block below, flows down, and is drained into a drainage ditch (not shown) built at the bottom of the slope. be.

(Effect of the invention) Since the invention is constructed in this way, the surface water on the filler surface flows into the water channel 4 in the block through the groove 2 on the top surface of the block, so that the surface water is transferred to the concrete manufacturing method frame of the plurality of blocks. Water is led directly to the water collection basin 8 in units of squares surrounded by blocks, which ensures that the water can be treated within the water channel 4, and prevents surface water from pouring concentratedly into specific areas. It also has the effect of reducing the moisture content of the seawall, making it perfect for revetment of the closed surface.

Even if garbage, empty cans, etc. accumulate in the groove 2 and flow down the groove 2 along with rainwater, the water collection basin lid 10 can be fitted to prevent the garbage or empty cans from falling into the water collection basin 8, thereby clogging the waterway 4. This prevents rainwater from concentrating in one place and stagnating, and there is absolutely no erosion or scouring of the filler surface, and the slope is reliably protected and will not be destroyed.

Since the flowing part of the water channel 4 is an impermeable layer made of concrete material, the flowing sewage does not penetrate into the ground and is reliably guided to the water collection basin 8, and the water channel part is formed into a smooth surface. Because the roughness coefficient is small, the water force does not weaken, and even if dirt, etc. flows in, it is swept downward by the strong water force, allowing efficient rainwater treatment.

Furthermore, by extending the water channel 4 in the axial direction, it is possible to reduce the weight of the concrete manufacturing frame block, which also has the effect of improving the workability and safety of construction on slopes.

As described above, the present invention is a useful device that has a robust structure, protects the slope in multiple layers, and completely prevents the slope from being destroyed.
