[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope forming block used for earth retaining or revetment.

[0002]

2. Description of the Related Art As a conventional block of this type, a block made of concrete having a substantially quadrangular pyramid shape is known.

[0003]

[Problems to be Solved by the Invention] However, in the conventional blocks, there is a problem that the labor cost is high and the construction period is long because the skill is required to accumulate the blocks.

In view of the above, the present invention provides a slope forming block which can be easily and quickly constructed by a general worker without requiring skill and can form a strong slope. The purpose is.

[0005]

In order to achieve the above object, in a slope forming block of the present invention, a foundation block laid and fixed on foundation concrete, and a first-stage block stacked on the foundation block. , A combination with a second-stage block that is sequentially lifted up on the first-stage block, each of the blocks having an opening in the upper surface thereof and having a substantially U-shaped cross section having at least front and rear walls and a bottom portion, Engagement step portions are formed at the opening edge portions of the blocks and the bottom portions of the blocks stacked with respect to the opening portions so as to prevent the displacement in the front-rear direction by engaging with each other.
An upper end opening of the base block is opened rearward in a slanted shape, and front and rear walls of the first stage block are formed in a rearward slanted shape and an upper end opening thereof is formed substantially horizontally. The blocks are configured such that the front and rear walls thereof are inclined rearward, the upper end opening and the bottom surface are horizontally formed, and a required number of through holes are formed in the bottom of each block.

[0006]

Since the present invention is constructed as described above, the foundation block is first laid and fixed on the foundation concrete, and the hollow portion of the foundation block is filled with concrete.

Next, after stacking the first-stage blocks in a state where the bottom portion is overlaid on the inclined opening portion of the basic block,
Concrete is filled in the hollow portion of the first-stage block.

Next, after stacking the second-stage blocks in a state where the bottom portion is overlaid on the upper surface opening of the first-stage block,
Concrete is filled in the hollow portion of the second block.

Next, after stacking the second-stage blocks in a state where the bottom portion is superposed on the upper opening of the second-stage block,
Concrete is filled in the hollow portion of the second block.

As described above, by stacking the required number of second-stage blocks, a slope having a required height can be formed.

[0011]

1 to 3 show an embodiment of the present invention.
In the figure, 1 is a basic block, 2 is a first stage block, 3
Indicates the second block.

The foundation block 1 is a block laid on foundation concrete 4, and has a horizontal bottom portion 10,
It is formed in a substantially U-shaped cross section with an upper end opening 11 inclined toward the rear and vertical front and rear walls 12, 13.
An engagement step portion 14 having a recessed inner surface is formed at an opening edge portion of the upper end opening portion 11, and two circular through holes 15 are formed in the bottom portion 10.

The first-stage block 2 is a block that is stacked on the basic block 1 and has a bottom 2 that is inclined along the inclination of the upper end opening 11 of the basic block 1.
0, front and rear walls 22 and 23 inclined rearward, and a horizontal upper end opening 21 are formed in a substantially U-shaped cross section,
An engagement step portion 24 having an inner surface recessed is formed at the upper edge of the opening. The bottom 20 has two circular through holes 25.
And the engaging stepped portion 1 of the basic block 1 is opened.
An engagement step portion 26 that engages with No. 4 is formed.

The second-stage block 3 is a block in which a required number of stages are stacked on the first-stage block 2.
A bottom portion 30 formed horizontally along the plane of the upper end opening 21 of the first block 2 and a front and rear wall 3 inclined rearward.
2 and 33 and a horizontal upper end opening 31 having a substantially U-shaped cross section
The upper end opening edge portion is formed in a letter shape, and an engagement step portion 34 having a recess on the inner surface side is formed. And the bottom 30
Two circular through-holes 35 are formed in the hole, and an engagement step portion 36 that engages with the engagement step portion 24 of the first block 2 and the engagement step portion 34 of the second block 3 is formed. There is.

On both sides of each block 1, 2, 3,
Lower reinforcing side walls 17, 27, 37 are respectively formed. As the blocks 1, 2, and 3 stacked on both sides of the slope, those whose entire side surfaces are closed by side walls (not shown) are used.

Since this embodiment is constructed as described above, first, the foundation block 1 is laid on the foundation concrete 4, and the hollow portion of each foundation block 1 is filled with concrete, and the upper surface thereof is engaged. The surface of the portion 14 is leveled along the inclination.

Next, after stacking the first-stage blocks 2 with the bottom portion 20 stacked on the inclined upper-end openings 11 of each base block 1, concrete is filled in the hollow portion of each first-stage block 2, The upper surface is leveled horizontally along the surface of the engagement step portion 24.

Next, after the second-stage blocks 3 are piled up with the bottom portion 30 stacked on the horizontal upper end opening 21 of each first-stage block 2, concrete is filled in the hollow portion of each second-stage block 3. Then, the upper surface thereof is leveled along the surface of the engagement step portion 34.

Next, after the second-stage blocks 3 are piled up with the bottom portions 30 stacked on the horizontal upper end openings 31 of the respective second-stage blocks 3, concrete is placed inside the hollow portions of the respective second-stage blocks 3. To fill.

As described above, by stacking the required number of second-stage blocks 3, the slope having the required height can be easily and quickly formed. The slope thus formed has excellent strength because the concrete in each of the blocks 1, 2 and 3 is integrally connected through the through holes 15, 25 and 35.

It is desirable that the back-filled crushed stone 5 at the rear of the slope be laid every time the blocks 1, 2, and 3 are raised one step. Further, the strength can be further increased by using the through holes 15, 25 and 35 to pass the reinforcing bar.

[0022]

As described above, in the slope forming block of the present invention, since the slope is formed by stacking the blocks so that the bottom portion overlaps the upper end opening of each block,
It can be easily and quickly performed by ordinary workers without requiring skill, and the concrete filled in each block is integrally connected to each other through the through hole opened at the bottom of each block, so it is strong. There is an effect that a smooth slope can be formed.
