Abstract

PROBLEM TO BE SOLVED: To facilitate manufacture by obliquely unifying and erecting a pot wall plate having an angle corresponding to the gradient of a slope face to a slope-face protective plate and proper thickness and height on the slope-face protective plate. SOLUTION: A rear is formed in one wall on the side laid on the slope face in a slope-face protective plate 2 having proper thickness. The slope protective block is formed in a shape that slender bowl wall plates 3 are installed to the slope-face protective plate 2 by obliquely unifying and erecting a plurality of stages of the pot wall plates 3 having proper thickness and height at an angle corresponding to the gradient G of a slope face to the slope-face protective plate 2. The thickness of the slope-face protective plate 2 is formed in size thicker than the thickness of the pot wall plate 3, and these thickness is determined properly in consideration of the balance of the weight of earth cover executed to the bowl wall plate 3 and the earth pressure of the slope face of the slope-face protective plate 2. Accordingly, manufacture is facilitated, the area of a manufacturing yard can be utilized effectively while structure is stabilized and can be simplified, and rapid and economical laying execution is carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a block laid in a multistage manner for protecting slopes along steep slope cuts and embankments along roads and in development sites such as housing complexes, and steep seawalls of rivers. The present invention relates to a multi-stage vegetation type slope protection block capable of covering the soil and vegetation to enable greening of the slope.

[0002]

2. Description of the Related Art Cut steep slopes of a developed land as described above,
Conventionally, in order to protect an embankment or a slope on a steep shore of a river, two sides having a reverse-eight-shaped cross-section as shown in the plan view of FIG. 4, the front view of FIG. 5, and the side view of FIG. Single blocks integrated by connecting plates (not shown) between the respective side walls of the large vegetation block 1 having the side walls are sequentially stacked in multiple stages along the slope, and the soil is covered between the upper and lower large vegetation blocks 1 having a step shape. And
Vegetation is applied to green the slope.

[0003] However, the large vegetation block 1 as described above has a complicated structure and lacks stability in its shape, so that the production cost increases and the work of laying on the slope is not easy. There's a problem. In addition, since the block is made of concrete, there is a drawback that underflow water from the slope is blocked by the block, and water is not supplied to the vegetated cover soil on average.

[0004]

SUMMARY OF THE INVENTION The present invention simplifies the structure of a slope protection block used for protecting a slope having a steep slope and increasing the degree of greening of the entire slope, and has a stable shape. Multi-stage vegetation type, which makes it easy to manufacture, improves the workability when laying on the slope, and can supply underground water from the slope to the vegetated soil evenly. Provide a slope protection block.

[0005]

SUMMARY OF THE INVENTION A multi-stage vegetation type slope protection block according to the present invention has an angle corresponding to a slope of a slope, an appropriate thickness and a height, with respect to a slope protection plate having an appropriate thickness. A multi-stage vegetation type slope protection block, which is formed by diagonally integrating a pot wall board having a slope with a slope protection board, and the weight of soil covering the pot wall board and the slope earth pressure of the slope protection board. In consideration of the balance with the above, the wall surface of the slope protection plate is formed to be appropriately thicker than the wall thickness of the pot wall plate, and is composed of a multi-stage vegetation type slope protection block.

Further, the present invention provides a multi-stage vegetation type slope protection block having a plurality of pot wall plates attached to the slope protection plate, and at least a slope protection plate of the slope protection plate and the pot wall plate. Preferably, it consists of a multi-stage vegetation slope protection block in which both plates are formed of porous concrete.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a multi-stage vegetation type slope protection block in one embodiment, and FIG. It is sectional drawing.

First, as shown in the figure, a slope protection plate 2 having an appropriate thickness is used as one wall whose back surface is laid on the slope, and the slope of the slope is inclined with respect to the slope protection plate 2. A plurality of pot wall plates 3 having an appropriate thickness and height at an angle corresponding to G are obliquely integrated with the slope protection plate 2 and erected, thereby forming a long and narrow pot wall plate on the slope protection plate 2. 3 is attached.

In the figure, reference numeral 4 denotes a drain hole, and in this embodiment, the thickness H of the slope protection plate 2 is formed to be larger than the thickness T of the pot wall plate 3. The determination of T is H is based on the weight of the soil covering 5 applied to the pot wall plate 3 as shown in FIG.
It is appropriately determined in consideration of the balance between the slope protection plate 2 and the slope earth pressure, whereby the strength and weight of the entire multi-stage vegetation slope protection block are balanced, and its structural The simplicity of the construction is also provided, and the construction is laid on the slope to provide weight and strength and stability.

Further, in this embodiment, the slope protection plate 2
And the pot wall plate 3 are integrally formed of porous concrete. Next, FIG. 3 shows an example in which the above-mentioned multi-stage vegetation type slope protection blocks are stacked in three levels for slope protection with a steep slope. After the top concrete 7 was cast, the backfill stones 8 were packed on the slopes, and each block was piled up. Then, the soil covering 5 was placed in each pot wall plate 3 and vegetation indicated by 10 was applied. As a result, the concrete surface of each block is almost hidden, and almost 100% greening can be expected.

As described above, since the structure of the small pots can be made relatively small by the pot wall plates 3, the connecting reinforcing plates of the slope protection plates 2 can be omitted. In addition, when the above block is manufactured, since it can be manufactured only with the vertical frame with the cross section of the edge being up and down, the manufacture is easy, and each block of the slope protection plate 2 provided with a plurality of small step pots is used. By increasing the size to a size that can be transported, the efficiency of the laying work on the slope is improved and the workability is improved.

[0012]

According to the multi-stage vegetation type slope protection block of the present invention described above, the production is easy, the area of the production yard can be effectively used, and the structure can be stably simplified. Rapid laying is possible and economical laying is possible.

[0013] By covering the soil between the pot wall plates and vegetation, the slope can be made almost 100% green, and by forming each block with porous concrete,
Not only can drainage of the underground water from the slope be drained, but also water can penetrate the entire slope protection wall, and the average vegetation can be replenished between the vegetation pot walls to maintain vegetation.
