[Embodiment of device]

 First, the block material for a retaining wall of the present invention according to claim 1 is composed of two constituent members, a block body and a base member.

Of these, the block body is formed such that recesses are provided on both upper and lower surfaces so that the longitudinal cross section in the longitudinal direction is substantially I-shaped, and the recessed portion in the middle of this substantially I-shaped is in this substantially I-shaped. It is a relative shape to a convex shape in which two convex portions on the outer side are in contact with each other at their side faces and are formed. In addition, at least one of a protrusion and a fitting groove orthogonal to the width direction of the block main body, for example, a protrusion on the upper surface and a fitting groove on the lower surface are fitted on each of the upper and lower surfaces and both the left and right surfaces. It is provided so as to correspond to the male and female on each of the upper and lower or left and right facing surfaces so as to match. Further, the left and right side surfaces are provided with locking portions to form locking grooves communicating with the back surface.

As described above, the block main body is formed so that the longitudinal cross section is substantially I-shaped. This is because the convex portions formed by connecting the side surfaces of the other block body to each other are fitted in the concave portions on both the upper and lower sides, that is, a plurality of the substantially I-shaped block bodies are staggered so that they are engaged with each other. By stacking the blocks on top of each other, the block main bodies that are stacked on top of each other can be prevented from shifting in the left-right direction, and a strong connection structure can be obtained.

Therefore, the concave portions on the upper and lower surfaces of the block body are formed in a relative shape to the convex shape formed by communicating the two block bodies on the left and right sides.

Further, the longitudinal projections and fitting grooves formed on both the upper and lower sides and the left and right sides of the block body are such that when the block bodies are vertically stacked and communicated with each other on the left and right sides. The fitting grooves and the projections are fitted in correspondence with each other in the space, and the connection prevents the block main body from slipping forward or moving vertically or horizontally. Therefore, the protrusion and the fitting groove must be in the male and female relative shape and at the relative position on the upper and lower surfaces and the left and right side surfaces of the block body. However, the number, length, size, and shape of the protrusions and fitting grooves are not limited as long as they are of the male and female relative shape. Further, the fitting groove may be at least one capable of inserting and fitting these ridges, and may be deeper than the length of the ridges, but for stable mounting. It is preferable that the upper and lower surfaces or the left and right surfaces of each of the stacking members and the left and right members are in close contact with each other when stacked and communicated with each other.

Note that these ridges and fitting grooves do not have to be convex or concave with respect to a common base plane, and for example, an intermediate portion between the convexes and the convexes is concave, or the concave and concave are It includes all that are recognized as protrusions and fitting grooves in a relative sense, such as making the middle part convex.

Locking grooves formed on both right and left side surfaces of the block body are for locking and locking a locking base portion of a base member which is another component of the present invention. The block main body and the base member are connected to each other, and the base member is buried and fixed to the ground to prevent the block main body from moving or collapsing in the front-rear direction.

Therefore, this locking groove must be shaped so as to fit with the locking base of the separate base member. Then, part or all of them must be connected to the back surface of the block body so that the fitted base member can be extended to the back surface of the block body. However, the shape may be rectangular, circular, or any other shape, and its size is not limited.

Further, since the locking groove is provided for fixing the block main body to the ground through the connected base member, the locking groove is provided with a locking portion for locking the base member. To be The position, shape, and material of this locking portion are, for example, those in which a projection made of concrete is integrally molded in the middle of the back surface of the locking groove, or one in which a steel locking ring is attached below the locking groove, or It may be of any type such as a stepped portion integrally formed with the locking groove as described in the embodiments described later.

Next, a base member, which is another component of the present invention, extends from the block body to the back surface thereof and is embedded in the soil to fix the block body to the ground. Is. Therefore, the shape and material are not limited as long as they fulfill this function, and they may be round steel bars, concrete square bars, concrete spheres, wooden boxes, or any other shape, but the block body is firmly grounded. A thicker or longer one is preferable in order to secure stability by fixing to.

Further, the base member is provided with a locking base portion which is inserted into the locking groove of the block body and is locked to the locking portion at least at one end thereof. By connecting these locking bases to the locking parts of the block main body, the base member is prevented from being pulled out from the block main body, and the function as the base member is exerted so that the block main body moves in the front-back direction or Collapse is prevented. The shape and size of this locking base portion are not limited as long as locking connection is possible. In addition, if this is provided at both opposite ends of the base member, the locking base arranged in the soil on the ground side becomes an antibody (anchor) that prevents the base member and the like from being removed from the soil. Therefore, it is even more preferable.

The shape and the like of the front surface portion and the rear surface portion of the block body can be freely formed and changed, for example, those having a projecting surface shape or having a pattern.

The retaining wall block material according to the present invention configured as described above can be fitted in the block body in any of the up-down direction, the left-right direction, and the rearward direction. These can be used in combination. It is also possible to unmate, and when refurbishing the retaining wall, the unit can be reused without destroying it.

Further, since each constituent member of the block material for a retaining wall is formed by one mold member in one shape and it is sufficient, it is possible to manufacture in advance in a homogeneous manner in a large amount at low cost. Inconveniences, difficulties, and dangers related to transportation work and the accumulation of various building materials at construction sites can be eliminated.

Next, the retaining wall structure of the present invention according to claim 2 has a convex shape formed by connecting side surfaces of another block body to the concave portion of the block body according to claim 1. The blocks engage with each other, and the protrusions and the fitting grooves provided on both the upper and lower surfaces and the left and right side surfaces of each of the block main bodies are mated with each other in a mating manner between the adjacent blocks, and at the same time, the base member is formed. The locking base is fitted into the locking groove of the block body, and a plurality of these block bodies and base members are connected and stacked.

The retaining wall structure is constructed by the following procedure. First, a plurality of block bodies according to the invention of claim 1 are communicated by fitting male and female protrusions and fitting grooves formed on the side surfaces of each other within a proper range on a pre-formed basic concrete. Let

Next, the locking bases provided at the ends of the base member, which are separate bodies, are inserted into the locking grooves formed in the side surfaces of the block main bodies that are in communication with each other and abutting against each other. The block main body and the base member are fixed by fitting with the locking portion provided in the lever locking groove. In this case, the base member projects to the back surface of the block body.

After the above work is completed, the protrusions (or the fitting grooves) on the upper surface of the block main body which are laid in a continuous manner and the fitting grooves (or the protrusions) provided on the lower surface of the second-stage block main body. ) And are stacked so that and fit together. As a result, the upper and lower block bodies are fitted and connected to each other to prevent displacement in the front-rear direction between them. At the same time, the central portion of the lower block body and the upper block body are placed on the lower block body. Place the upper block main body in a staggered manner so that the side surface of the block and the side surface of the block correspond to each other. Conversely speaking, one block main body in the upper stage is placed so as to evenly straddle the convex-shaped portions of the two block main bodies in the lower stage connected to each other. As a result, the recesses on the upper surface of the upper and lower stages of the substantially I-shaped block body, which are constricted, and the projections, which are protruded, are engaged with each other, and a lateral shift between them is prevented.

After the block main bodies of the second step are continuously provided, the locking base of the base member is fitted into the locking groove in the same manner as described above, and the base member is projected to the back surface of the block main body.

The above-mentioned continuous stacking can be extended infinitely, and the retaining wall construction range can be freely expanded or reduced. Then, after completing these operations within a certain range, backfilling backfilling into the ground is performed to complete the construction of the retaining wall. It should be noted that backfilling backfilling into the ground can be done very easily and quickly with artificial or mechanical arms.

As described above, the retaining wall according to the present invention constructed by the above-described procedure is fit and connected between the block main bodies and between the block main body and the ground, and is orderly in the vertical, horizontal, and front-rear directions. Safe and stable Retaining wall structure. In addition, the construction period is shortened, which is convenient for construction. In addition, it will be low cost and the convenience of repair and regeneration will be secured.
