DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to prevention of collapse of slopes such as mountains, rivers and lakes and improvement of earth covering blocks used for greening work.

[0002]

2. Description of the Related Art As shown in FIG. 1, a concrete covering block used in the industry for preventing collapse of slopes and the like and for greening has a square (25) wide and a bottom (26) as shown in FIG. It was a covered soil block (24). A drain hole (23) is provided to extend laterally through the surrounding rising outer frame (22) and the inner frame (27) forming the grid (25). Constructing a soil covering block (24) with such a configuration on the hillside, on the slope of a river or lake, etc.
Then, the soil was covered on top of it, and seeds of grass were sown on the soil cover to plan the greening. Japanese Unexamined Patent Publication No. 1-146022 is provided as a greening method for a mountainside or a river embankment. In this method, a cured soil seeded with grass seeds is attached to a rock wall or a slope constructed with concrete. The former method has the disadvantage that soil cover flows down due to heavy rain and only soil cover blocks remain, while the latter lacks fixation on sloped rock and concrete construction surfaces, and like the former, there is a disadvantage that vegetation blocks flow out due to heavy rain. .

[0003]

The problem to be solved by the present invention is that the drainage hole (23) is a small hole when a certain amount of rain falls in the above-mentioned conventional soil covering block, so that the soil penetrates the soil so that the soil covering block is infiltrated. (24) The accumulated rainwater cannot be completely drained, and the drain holes (23) are immediately clogged, and the drainage is not performed. There is a major technical and economical problem that it is necessary to solve this problem and make the greening of the construction surface permanent because of the defect that soil is re-covered each time. In the means disclosed in Japanese Patent Application Laid-Open No. 1-146022, the vegetation block constructed on the inclined surface is soil, so that the steeply-sloped rock wall or concrete surface has no holding power and has no retaining force as described in the specification. It is difficult to settle, and furthermore, the supply of water from the underground by capillary action is extremely small, causing the grass to die due to dryness. There is a problem. The present invention is to solve the above problems.

[0004]

The present invention employs the following means to solve the above-mentioned problems. That is, on a concrete base having an appropriate thickness formed so as to be able to be fitted and assembled in the front-rear and left-right directions, a plurality of earth retaining members projecting from the base at appropriate heights at appropriate intervals and being integrated with the base in parallel. A plurality of array groups are configured with the body as one array group, and the individual soil members forming each array group are zigzag so that the individual soil members forming the other array groups and their longitudinal lines cross each other. Arranged to form a plurality of zigzag earth retaining body rows, forming a zigzag rainwater flow path on the base, the flow path is provided with a plurality of drain holes vertically penetrating the base The above problem could be solved by fitting and assembling this to the construction surface, covering the soil, sowing grass seeds and planting small shrubs. The earth retaining body may have a trapezoidal cross section and may be formed in a horizontally long rectangular shape, or the earth retaining body may have a constant height, or may have a height difference to further improve the base. Was constructed so that its cross section became trapezoidal, thereby making the production of the covering block more efficient.

[0006]

4 and 5 show a second embodiment of a covering block according to the present invention. In the second embodiment, the arrangement of each of the soil retaining members is the same as that of the first embodiment, in which all the formed shapes such as heights are the same. This is a covering block in which the height of the earth retaining bodies in the group is arranged at the intersection of height.

That is, as shown in FIG. 4 and FIG. 5, the height of the earth retaining bodies (12), (12 ') and (12 ") of the first array group is the same as that of the earth retaining body (12) and the earth retaining body (12"). High, and the height of the intermediate soil body (12 ') is formed low, so that its upper base area (13) is equal to the upper base area (1) of the soil body (12) (12 ").
It is formed wider than 4). Next, the soil bodies (15), (15 ') and (15 ") of the second array group are soiled bodies (15) and (15").
The height of the earth retaining body (15 ') is increased. Earth retaining bodies (16) (16 ') (1)
6 ") is the height of the earth retaining bodies (12) (12 ') of the first array group.
(12 "), and the soil members (17), (17 ') and (17") of the fourth array group are combined with the earth members (2) (2') (2 ") of the second array group. Other configurations are exactly the same as those of the first embodiment.

Although the construction of the earth covering block of the present invention is as described above, the height (21) of the earth retaining bodies constituting each arrangement group may be arranged with various height differences other than those shown in the embodiment. Needless to say, the arrangement angle α of the soil body of each array group with respect to the base (5) can be freely set to be large or small, and the seepage water formed on the base by the soil body of each array group can be set. The angle α may be set so that the flow path (19) does not become linear, and has a complicated zigzag shape.

Next, in the case of performing the protection of the inclined surface and the greening work using the earth covering block (11) of the present invention, which describes the operation of the present invention, the formation angle α between the surface of the base (5) and each earth retaining body.
Regardless of the size, the angle at which the covering block (11) is attached to the horizontal surface is determined so that the rainwater flow path (19) will not be linear at all in consideration of the inclination angle of the slope of the construction site, the annual rainfall amount, soil quality, etc. Then, the individual covering blocks (11) are fitted and assembled in the front, rear, left and right directions, and are attached to the inclined surface. Of course, in the lowermost construction section, it is natural to carry out necessary foundation construction. At the time of assembling, the mounting brackets (20) provided in advance are appropriately tightened to each other with a wire or the like, and a reinforcing bar is inserted into a reinforcing-bar insertion hole (28) to be connected, and the mounting joint is filled with mortar. In that case, the construction surface is covered with the earth covering block (11) of the present invention, is formed in a zigzag shape by the earth retaining body, and the branch road (2) is formed in the middle.
The rainwater flow path (19) in which 9) is also formed is configured in multiple layers. Of course, the rainwater flow path (19) is always formed with a gentle inclination downward, and there is no place where it goes backward.

As described above, the covering block of the present invention can be constructed by adjusting the angle of attachment to the horizontal plane.
If the earth α is formed at a constant angle when the earth retaining body is integrally arranged on the base (5), the necessity of manufacturing and preparing a plurality of types of covering blocks (11) having different angles α is reduced. However, depending on the construction site, it may not be possible to use a covering block that has been manufactured with a predetermined angle α. Therefore, the covering block (11) of the earth retaining body having the angle α corresponding to the construction site is manufactured and used. It could be. The height (21) of the earth retaining body is suitably at least about 10 cm or more and about 30 cm. However, the height of all earth retaining bodies in all the arrangement groups is constant and the covering block (11) having a large height is used. Whether to use, to use a relatively low height, or to use a covering block (11) consisting of arranging earth retaining bodies having a difference in height, is selected according to various conditions such as the inclination angle of the construction site. It is good.

When the sticking work is completed on the construction slope or the like, the soil is covered over the entire surface of the covering block (11), but the covering is performed to such an extent that all the earth retaining bodies are hidden. Then, grass seeds are sown on the cover soil to plan the greening. At this time, if it is possible to place the rainwater flow path (19) at the position, the drain hole (1
It is advisable to plant a small shrub at the position 0). There is no problem if there is rainfall on the fitting and attaching work surface by the soil covering block (11) of the present invention, and if the rainfall is the allowable moisture content of the covering soil, but if the rainfall exceeds the allowable amount, a part of the rainfall is drained. It penetrates into the ground through the holes (10), partly flows on the soil cover surface and partly penetrates and flows between the soil cover and the base. At this time, the water flowing down the rainwater flow path (19) flows in a zigzag manner, and a part of the water branches off and flows down to the branch path. The falling rainwater is blocked by the earth retaining body and does not flow linearly even on an inclined surface, and therefore does not flow by being urged. The earth retaining bodies arranged obliquely with the angle α function to prevent the earth from flowing down.

[0012]

Since the present invention has the above-described structure and operation, the conventional covering block (24) can be used during heavy rain or heavy rain.
Then the rainwater infiltrating into the block is the surrounding rising frame
(22) and drain holes (23) formed in the inner frame (27)
Because the holes are small holes, they easily clog and easily exceed the discharge limit, and the rising frame (22) completely prevents the rainwater from flowing down, so that the rainwater stays in the soil covering block (24) and the soil becomes muddy. At the same time, it goes up and down with rainwater. The same applies to the case where grass seeds are sown and greened on the soil cover. On the other hand, in the case of the present invention, the rain falling on the soil cover block (11) not only flows down the surface but also a large amount of seeping rainwater flows. However, a part of the soil penetrates into the ground through the drain hole (10), and a part of the water flows constantly without being urged in a zigzag shape according to the rainwater flow path (19). Block (1
Since there is no rising frame in the four surroundings of 1), the amount of water staying on the base (5) is small. Therefore, the soil covering (18) floats by the staying water on the base (5) as in the conventional block (24) of this type. This has an extremely great effect that muddy water does not flow down at once. Of course, the above effect is amplified because many earth retaining bodies are arranged in a zigzag shape to prevent the earth from flowing down. In addition, the drainage hole (10) is made as large and wide as possible on the sloping surface constructed by the soil covering block (11) of the present invention on the premise of planting grasses and small shrubs. Hole (1
0), and extends into the soil (18) on the base (5) and also extends from the adjacent drainage hole (10) into the ground. In addition to fixing the soil on the slope by its own weight and the weight of the soil cover (18), the rooting of the planting shrub has a great effect of preventing collapse of the soil cover block (11) and prevention of soil loss. Also, even if the covering block is made of concrete,
There are many drainage holes (1
0) has the effect that it does not die due to the replenishment of water due to the capillary action, and the covering block (11) of the present invention has a special polygonal shape and is fitted and assembled with the block (11) adjacent to the front, rear, left and right. Naturally, each covering block (11) is fixed by the mounting metal fittings, and each covering block (11) is jointed with mortar by jointing with the reinforcing bar inserted through the insertion hole (28). Since it is buried and integrated as a whole, no cracks are easily generated on the construction surface, and since the covering does not flow out unlike the conventional covering block, there is no need for re-covering work, which is economically significant. This has a great effect that an extremely natural greened inclined surface appears and is maintained. In addition, when the revetment of a river or lake is constructed by the earth covering block (11) of the present invention, especially in a portion below the surface of the water, in the case of a river, the water is cut off by the soil retaining body, and the sediment or the flowing dust between the soil retaining bodies. There is also an effect that aquatic plants are generated and become a habitat for fish and restore natural conditions to the river flow. The same applies to lake shores. In addition, since the base (5) and the retaining body are formed in a trapezoidal shape, there is an advantage that the block (11) can be easily removed from the manufacturing process.
