Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a slope block used for slope protection work.

(Prior Art) Conventionally, as a legal frame block, the one shown in FIG. 9 has been proposed.

This legal frame block 1 is a substantially rectangular block body with joints 2 provided at both ends. A large number of these legal frame blocks 1 are arranged vertically and horizontally to form a grid, and these are anchored (not shown).
Stop on slope 3 with , divide slope 3 into a grid pattern,
This makes it possible to protect and stabilize the slope 3. In addition, the gaps 4 at the corners of the lattice 6 formed by the joints 2 at both ends of the lattice blocks 1 are filled with concrete to connect the lattice-shaped lattice blocks 1 to each other. There is.

Then, depending on the situation at the site, that is, depending on the slope slope, soil quality, etc., soil may be applied to the lattice 6 formed by the slope block 1 to be used as turf or seeding. It was sometimes covered with chestnut stone, cobblestone, or lining block.

(Problem to be solved by the invention) However, in the case of this legal frame block 1, it is constructed to form a lattice-like structure, and the inside of the lattice 6 formed by each block 1 is lined with chestnut stone or cobblestone. In this case, cracks occurred in the frame block 1 due to the load of the chestnut stones or cobblestones.

In addition, in the case of this slope block 1, when it is constructed in a lattice shape and the inside of the lattice 6 formed by each block 1 is lined with an inner block,
As shown in FIG. 9, four approximately triangular lining blocks 5 are lifted up with a crane and placed inside the lattice 6 to cover the inside of the lattice 6, and mortar is filled between each lining block 5. It is necessary to fix the lining block 5 within the lattice 6, and performing such work on the entire slope 3 is very complicated and requires a lot of work time.

The present invention was developed in view of these problems, and it reduces the occurrence of cracks caused by the load of chestnut stones or cobblestones, and also allows slope protection work to be carried out easily and in a short period of time even when using inner block cladding. The purpose is to provide a slope block that can perform the following steps.

(Means for Solving the Problems) That is, the present invention has a slope section provided in a lattice shape and a slope section extending to the side of this slope section when a large number of them are lined up on a slope to cover the slope. In a legal frame block consisting of an inner lining part that forms drainage holes when the frame part is provided in a lattice shape, the legal frame block is a substantially square block body, and the legal frame parts are provided diagonally. This is a legal frame block characterized by having a lining part extending laterally so as to be perpendicular to the legal frame part.

(Function) Therefore, in the slope block of the present invention, the slope sections provided diagonally on the block body are provided in a lattice pattern on the slope to cover and protect the slope. In addition to stabilizing the lattice, an inner lining part extending to the side of the lattice part perpendicularly to the lattice part lines the inside of the lattice formed by the lattice part. A drainage hole is formed in the

As shown in FIGS. 1 to 3, the slope blocks 11 of the present invention are arranged in large numbers on the slope 13 in the vertical and horizontal directions to cover the slope 13 and protect and stabilize the slope 13. It is in block type. A legal frame portion 14 is provided on the diagonal line, and a legal frame portion 1
An inner lining part 15 extends on the side so as to be orthogonal to 4.

As shown in FIGS. 1 to 3, the legal frame portion 14 is manufactured to have a trapezoidal cross section, and has a pair of contact surfaces at both ends that abut against another adjacent legal frame block 11. a generally hexagonal joint 12 having 16
is provided. Further, a reinforcing bar 17 is passed through the inside of the legal frame part 14 in the longitudinal direction, and both ends of the reinforcing bar 17 protrude into the joint part 12, respectively. When a large number of the legal frame blocks 11 are arranged vertically and horizontally on the slope 13, the legal frame parts 14 are provided in a grid pattern on the slope 13, and the slope 13 is covered by the legal frame parts 14. It is divided into a grid for protection.

As shown in FIGS. 1 to 3, the middle part 15 is a substantially triangular plate manufactured at the same time as the above-mentioned legal frame part 14, and when the legal frame blocks 11 are arranged in the vertical and horizontal directions, The inside of the lattice 18 to be formed is covered by four lining parts 15 extending from the sides of the lateral frame part 14 so as to be perpendicular to the lattice part 14, and these four lining parts 15 ,15,
A drain hole 19 is formed in the center of the grid 18 covered by the grids 15, 15.
As shown in FIGS. 1 to 3, the drainage holes 19 are holes formed in each of the inner lining parts, and are formed in each inner lining part 15 depending on the slope of the slope 13, soil quality, etc. By changing the size of this drainage hole 19, it is possible to cover almost the entire inside of the lattice 18 with the lining part 15 and use it as a mere drainage hole, or to use it as a mere drainage hole, or to cover it with soil. It has come to be covered with grass or sown seeds, or covered with chestnut stone or cobblestone. When using chestnut stones or cobblestones, since the sill section 14 is reinforced by the middle part 15, it is possible to reduce cracks that occur in the sill frame block 11 due to the load of the chestnuts or cobblestones.

The process of installing the thus constructed legal frame block 11 on the slope surface 13 will be explained.

First, as shown in FIG. 4, the slope blocks 11 are placed on the foundation concrete 20 poured at the lower end of the slope 13 at fixed intervals in the lateral direction, that is, at intervals equal to the width of the slope section 14. place Next, as shown in FIG. 5, the legal frame block 11 is placed vertically on each joint 12 of the horizontally installed legal frame block 11.
