Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to a wall for protecting a cut slope of earth or rock.

Traditionally, such cut-off slopes have been protected by stacking stone walls, small concrete blocks, or by covering the entire surface with concrete walls.

However, stone walls and concrete block masonry require a lot of manual labor and are not strong enough, and concrete walls have a risk of collapsing due to poor conformity with the cut surface, and are extremely bland. . The purpose of this invention is to use a special large-sized reinforced concrete block to cover the cut surface efficiently and to fit well with the cut surface, and to create a wall that can also be used as a planting bed if necessary. do.

Next, the present invention will be explained based on illustrated embodiments.

In FIG. 1, reference numeral 1 denotes a slope, and 2 and 3 denote an upper block and a lowermost block stacked against the front of the slope 1.

Since each block has a height of 2 to 3 feet, when the height of the slope 1 is large, more blocks of the same shape as the upper block 2 are stacked. As shown in FIGS. 2 to 5, the upper block 2 includes a top plate 21, a bottom plate 22, and a main wall 23, which are integrally formed with reinforced concrete to form a single character shape.

The top plate 21 and the bottom plate 22 are provided with ridges 24 and grooves 25 of the same shape, respectively, in parallel with the king wall 23, and the rear of the top plate 21 and the bottom plate 22 are provided with cutouts 2 of the same shape, respectively.
6, 26, 26 and 27, 27, 27 are formed. An anchor hole 28 and drain holes 29a, 29b, and 29c are punched in appropriate positions in the bottom wall 23, passing through the front and back.
As shown in FIGS. 6 to 8, the lower block 3 also has a top plate 31, a bottom plate 32, and a main wall 33 integrally formed of reinforced concrete.

The top plate 31' has a ridge 34 having the same shape as the top plate ridge 24 of the upper block 21, and a notch 35 having the same shape as the top plate notch 26.
, 35, 35, and an anchor hole 36 and drain holes 37a, 37b, 37c pass through the main wall 33. A projection 37 projects downward from the front green of the bottom plate 32. 1st again
In the figure, a groove 4 is excavated below the slope 1, crushed stone or chestnut stone 5 is poured into the groove, and a lower tier is placed on top of the groove 4.

The bottom plate 32 of the rack 3 is layered, and the anchor holes 36 are inserted as necessary.
The anchor 38 is driven into the slope surface 1 through it. Then, the gap between the main wall 33 and the slope 1 is filled with concrete 6 through the notch 35 of the upper plate 31 up to the height of the lowest drainage hole 37c, and then crushed stone or chestnut stone 7 is poured upward through the notch 35. Fill. The upper block 2 is stacked on the lower block 3 by engaging the groove 25 of the bottom plate 22 with the ridge 34 of the lower block upper plate 31, and attaching the bottom plate 22 to the lower block upper plate 31 using bolts (not shown). and then drive the anchor 30 into the slope surface 1 through the anchor hole 28 as necessary.

Concrete 8 is then passed through the notch 26 into the gap between the main wall 23 and the slope 1 to the height of the lowest drainage hole 29c.
and then filling with crushed stone or millet 9 above. Finally, the top surface of the top plate 21 of the top block 2 is
Cover the slope 1 with concrete 10 up to the height of the top.

In addition, 11 and 12 are the lowest drainage holes 29c of each block.
and a drainage pipe extending forward from 37c, and 13 is a drainage ditch provided in the ground below the slope 1. When installing tree planting registers 14 and 15 as shown in the first diagram, the bottom plate 2 of each block
Iron shelves 16 and 17 are set up along the front edges of soils 18 and 1, respectively, and synthetic resin boards are placed inside them, and then soil 18 and 1 are placed.
9 will be accommodated and trees will be planted.

Then, a water conduit 42 is installed along the back side of each block from the irrigation groove 41 provided in the concrete top through the notches 26, 27, and 35, and the ends of the water conduit 42 are passed through the drainage holes 29b and 37b. Openings are made into soils 18 and 19, respectively. The drain pipes 11 and 12 mentioned above protrude further forward than the iron fences 16 and 17 and are open. The above-mentioned construction can be carried out efficiently by a small number of people by transporting blocks made in advance at a factory to the work site and piling them up using a hoist. Furthermore, during work, since the size of the space behind the block is defined by the top plate and the garden slope, the thickness of the layer of crushed stone or chestnut stone can always be maintained at an appropriate thickness. The slope surface covering with the above-mentioned blocks acts as a covering to prevent the cut slope surface from being directly exposed to the atmosphere, and at the same time, it also absorbs dirt from the slope surface.

Furthermore, since each block is independently provided with a layer of crushed stone or chestnut stone behind it, it blends well with the slope, effectively reducing mudslides and draining water. Therefore,
Suitable for protecting rocks that are prone to collapse and cut surfaces of rocks that are easily weathered. In addition, since the bending moment applied to the completed wall is divided into each block, the reinforcing bars required for reinforcing each block are much thinner and smaller than conventional concrete coverings.

However, the protrusion 37 of the bottom plate of the bottom block digs into the ground, and the stacked blocks have grooves 25 and ridges 24,
34, so there is no risk of it protruding forward and collapsing. Note that the tree planting bed can be provided on the bottom plates 22, 32 by using the forwardly extending portions thereof, thereby improving the bland appearance caused by only concrete.

A drainage pipe prevents a large amount of water from flowing into the planting bed from behind the garden wall, and a drainage ditch 41 is installed as necessary.
Since the trees can be safely rinsed with water, it is easy to manage the trees.
As described above, according to the present invention, while installing a layer of chestnut stone or the like of sufficient thickness on the cut slope surface, it is possible to inexpensively and efficiently construct a slope that is strong and blends well with the slope surface. It is.
