BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the improvement of concrete blocks used for revetments and the like, which is intended to contribute to the protection and maintenance of the natural environment.

[0002]

2. Description of the Related Art A conventional concrete block (hereinafter referred to as "block") of this type is a square, a parallelogram, a rhombus, a rectangle, etc., whose area is 1 m2 (for transportation, construction, etc.). Considering the above, it is customary in the industry to set the area to 1 m2.) There is also a structure made with concrete and arranging suspicious stones, but generally there is a certain degree of geometry on the surface. When the blocks are mass-produced in a form that expresses a geometrical concavo-convex pattern and is constructed, the abutting part of each block becomes a straight line, and the mortar is used to fill the joints so that no gap is created in the linear abutting part. It is normal. In addition, when constructing the above-mentioned geometrical figure-like blocks, there was also a block that was constructed so that joints could be constructed with appropriate intervals and that after the construction, sand and sand were poured into the joints to grow plants and trees. Since the (joint) is a straight line, the sediment at the abutment (ditch) will be washed away by the water flow of the river, the waves of the lake, or the rainfall, and eventually the soil that supports the root of the block will be washed away. Large-scale revetment blocks (especially for small rivers) include retaining wall blocks and large U-shaped ditches. If any of these blocks, including the above-mentioned blocks, is used, lakes and river embankments and coasts will be concrete.
It is the current situation that it has taken away greenery and destroyed nature only by turning it into a tree.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional techniques, the problem to be solved by the present invention is to construct a concrete block having a certain unit area used for revetment of rivers, lakes and marshes. The abutment line that is sometimes formed is stopped from being a straight line, and it is made as complicated a zigzag line as possible, and it is not a straight line shape by filling joints with mortar to form a straight line, but it has a certain width and a constant width. No complex zigzag abutment groove.In addition, the suspicious stones placed in one unit block are also arranged so that the array after construction is not aligned in a straight line to reduce the influence of running water and rushing waves and abutment grooves. Vegetation is easy to grow, and suspicious stones and pedestals look like natural rocks and stones, and the concrete block construction of the present invention minimizes natural destruction and destroys it by conventional construction. Lies in the fact that to win back the green and nature in levees and banks such as natural rivers and lakes.

It goes without saying that the number of doubt stones can be freely selected.

[0006] Fig. 4 is a plan view of a revetment using a unit block. The assumed position of the complex polygon (outer form), the abutting hand, the connecting hand, and the assembling positions of the front, rear, left and right unit blocks. It is a top view which shows the relationship of. As shown in the assembly drawing in FIG. 5, even when the unit blocks have the same shape, the front and rear and left and right unit blocks are arranged such that the corresponding suspicious stones are staggered. In that case, suspicious stones (3) with the same arrangement (arrangement) in the outer formwork (1) having similar top, bottom, left, and right polygons
Since (3A) (3B) (3C) (3D) is molded in the inner formwork (2), the front and rear and left and right unit blocks can be assembled by reversing the front, rear, left and right. The assembling direction lines (9) and (10) are not formed in the straight line shape shown by the dotted line in FIG. 4 but become complicated zigzag lines, and even in the abutment groove (11) formed by the unit blocks facing each other on the assembling line. There are wide and narrow widths, and the shape is the same as a complicated meander every other pair of unit blocks.
Therefore, the suspicious stones (3), (3A), (3B), (3C), and (3D) are arranged in the same manner for every pair of unit blocks. Therefore, as shown in FIG. 5, the suspicious stones (3) (3A) ( 3B) (3C)
The arrangement of (3D) has an irregular appearance, and the abutting grooves (11) in the vertical and horizontal directions are also constructed such that the groove lines and the groove width have an irregular appearance. Of course, at the time of construction, the corresponding abutting hands (4) on the front, back, left and right have their end faces abutting and supporting each other, and the connecting hands (5) are connected to each other to support the unit block. The width and groove of the abutment groove (11) are formed by the abutment of the abutment hand (5) protruding from the pedestal (2 ') and the contour shape of the inner formwork (2), but the inner formwork ( The outer edge (outline) of 2) is formed so as to protrude from the peripheral edge of the pedestal (2 '), and the clearance (7) is formed by the width of the protrusion (H), and the abutment groove (11) is wider than the flat width. It is wider by that amount. When the above arrangement, abutment, and connection abutment construction are completed, soil (12) is put in the abutment groove (11) and grass and small shrubs are planted there to restore nature to the revetment construction site. .

[0007]

As described above, according to the present invention, suspicious stones are arranged in a complex polygon whose top, bottom, left and right are similar, and the tip end face of the abutting hand is always positioned parallel to the side of the polygon. The unit blocks having such a structure are arranged in a staggered manner in the construction direction of the unit blocks during construction, and the vertical and horizontal abutment grooves generated by abutment and connection have a complicated width and shape. Since it becomes a meandering shape and the arrangement of large and small stones also has a complicated irregular shape, the water flow of the river flowing on the block construction surface does not flow linearly and smoothly on the side abutment groove, but the flow meanders or Is blocked by smooth stones of large and small sizes, the flow velocity drops, and shunting occurs in the direction of the longitudinal abutment groove, and stagnation of the flow occurs on the back side of the stones in the flow velocity direction.
Also, since the flow velocity decreases in the wide part of the groove and stagnation occurs, the aquatic plants planted in the abutment groove are not washed away by the force of running water, and the soil in the groove is also washed away by running water. Nothing. Of course, aquatic plants naturally grow and grow in the vertical abutment grooves below the surface of the water. Next, regarding the relationship between the vertical abutment groove on the water surface and water, the two waters that have fallen due to heavy rain are not collected in the abutment groove, but rather are supported by suspicious stones and the horizontal abutment groove. Will be divided into two. For example, as shown in FIG. 5 (embodiment), the rainwater flowing down the vertical abutment groove is placed in the uppermost unit block, which is a stone (3C).
When flowing down the abutment groove formed by (3B) and suspicious stone (3B) (3C), suspicious stone (3A) of the next unit block
At the end, the flow velocity is reduced and the flow is divided into the left and right lateral abutment grooves, and part of the flow proceeds to the next vertical abutment groove, but in the groove, the flow velocity declines in the wide groove portion (15), and stagnation occurs. In addition, the water flow split left and right also stagnates because the flow velocity decreases in the wide groove part on both sides.
Further, the water flow diverted to the right hits the suspicious stone (3A) and the suspicious stone (3C) opposite to this, and the flow velocity is reduced, and the water is stagnated at the relevant portion. Similarly, the water flow split to the left hits the suspicious stone (3) and splits into the vertical and horizontal abutting grooves, and the flow velocity is reduced at the wide groove portions (15). In this way, the water flows flowing through the abutting grooves are complicatedly meandered, and due to the wide and narrow groove width, and the obstruction of the water flow due to suspicious stones, it is impossible to flow down the vertical abutting grooves all at once due to a large amount of precipitation. The horizontal abutment groove is also sympathetic, so the soil in the vertical and horizontal abutment grooves will never be washed away. Of course, each abutment groove contains soil. As mentioned above, the top surface is almost flush with the pedestal, so the rain that fell on the construction surface of the unit block of the present invention flows down the entire construction surface. Although it is thought that it does, the soil in the horizontal abutment groove as well as the vertical abutment groove is washed away because the flow and flow velocity are obstructed by the suspicious stones (3) (3A) (3B) (3C) (3D). There is no such thing. Therefore, the planted plant grows perfectly. Naturally, even if it is called a vegetation, it should be avoided that it is a large tree, and it is almost limited to small shrubs, so select a tree that can grow sufficiently with the width and depth of the abutment groove. Good.
As is apparent from the configuration of the present invention, the vertical and horizontal abutment grooves have a suspicious stone peripheral edge (inner peripheral edge of the inner frame) protruding from the peripheral edge of the pedestal leg portion (13) to form a play gap portion, and the protrusion portion (open gap Part), the abutment groove is wide, and the amount of soil is large correspondingly, and the rooting area and volume of the vegetation are large, which promotes the growth of vegetation. However, water required for plants is always supplied by running water below the water surface of the revetment, and water is supplied to the plants due to the capillarity of rainwater and groundwater on the construction surface of the water surface, so there is no risk of plant death. In addition, since the flow of water and rainwater below and above the revetment construction surface (block construction surface) is not a straight line as described above, vertical and horizontal abutment grooves will not be washed away, so the width of the groove will be reduced. Even if it is adopted considerably wider than the conventional construction joint, the water does not flow into the pedestal leg from the location and the revetment unit block does not tilt and cracks occur on the revetment construction surface. Furthermore, when it is constructed on the revetment of lakes such as dams, the suspected stones above the surface of the water have the action and effect of eliminating the waves. Under the water surface, the plants planted in the vertical and horizontal abutment grooves are not only a good habitat for fish and water-dwelling organisms, but also aquatic plants naturally grow and promote the breeding of aquatic animals. Not only the vegetation planted as a habitat for above-ground organisms but also other plants naturally sprout and grow, so that it is effective in recovering the lost nature over the entire construction surface. In addition, when the construction surface in lakes and marshes requires special attention to the wave cancellation due to the wind direction, etc., embedding crushed stones in the abutment groove only on the construction surface that requires the wave cancellation is very effective.
In addition, on the construction surface above and below the water surface, water flow is obstructed by suspicious stones, so suspicious stones (upper surface of the pedestal), especially dust and sediment accumulated at the roots of suspicious stones, and vegetation conditions are set up. As it grows, the restoration of nature is accelerated, the conventional landscape of full concrete is eliminated, and the near natural landscape is restored to the construction surface. When natural stone patterns are drawn on the surface of suspected stones and pedestals using silica sand, white cement, pigments, etc., a revetment with a mixture of pseudo-natural stones and vegetation appears and the effect of the entire revetment construction surface is great. It also has the effect of becoming.
Next, if a through hole (6) is opened in the pedestal and soil is inserted and embedded in it, it is possible to plant appropriate vegetation in the through hole (6). Aquatic plants and above-ground plants grow properly, and the increased supply of water from the hole (6) due to capillarity hydrates the plants that grow around the suspicious stone. It also has the effect of helping water supply to the plants growing in the ditch. Further, since the unit block has a plurality of abutting hands (4) and a connecting hand (8) for abutting and connecting the unit blocks on the front, rear, left and right due to its structure, it is conventionally necessary to fill the joints with mortar in the construction of this type of block. It is possible to maintain the assembly force sufficiently without carrying out the construction, and this assembly force is further enhanced by embedding the vertical and horizontal abutment grooves with soil.
