Description

  The present invention relates to a wall-integrated foundation block used to construct a retaining wall.

  Traditionally, retaining walls have been built on riverbanks.

  In this retaining wall, a large number of concrete retaining wall foundation blocks are installed and fixed along the river edge on the ground below the cut slope. A retaining wall surface is formed by a set of front walls of the retaining wall construction stacking block stacked in the right and left, and in the gap between the back surface of this retaining wall construction surface (the back surface of the retaining wall construction stacking block) and the slope. It is built by filling hardeners such as crushed stone and concrete.

  The preferred embodiment of the present invention will be briefly described with reference to the drawings showing the operation of the present invention.

  The wall-integrated foundation block A of the present invention is installed and fixed at the site where the retaining wall W is formed via the bottom plate portion 3, and the building block for building the retaining wall W on the bottom plate portion 3 of the wall-integrated foundation block A In this case, the partition forming wall 4 integrally formed so as to rise upward on the bottom plate 3 is the basis of the small-mouth stopper wall 6 that covers the end of the retaining wall W. Thus, by installing and stacking the wall member 5 on the upper part of the partition forming wall 4, it is possible to form the fore wall 6 made up of the partition forming wall 4 and the wall member 5.

  Therefore, in the conventional retaining wall construction using the precast concrete small retaining wall, it was necessary to temporarily install the small retaining wall in the field, but according to the present invention, the wall-integrated foundation block A Since the installation of the partition forming wall portion 4 which is the basis of the small retaining wall 6 is completed at the same time, the temporary work is unnecessary, and the wall member 5 is stacked on the upper portion of the partition forming wall portion 4. Since the small-mouth stop wall 6 can be formed simply by installing, it is possible to shorten the construction time and labor (reduced labor) as compared with the prior art.

  In addition, the wall-integrated base block A of the present invention has the partition forming wall 4, but can be stably grounded at the bottom plate portion 3, so that the partition forming wall 4 is less likely to fall down. The safety is also significantly improved compared to the conventional installation method involving temporary work of the stopper wall.

  Further, the partition forming wall 4 can be used as a foundation of the partition wall 7 by setting the installation and fixing position of the wall-integrated foundation block A at the site where the retaining wall W is formed. By stacking and installing the wall member 5, the partition wall 7 that partitions the retaining wall W at a predetermined interval can be easily and safely formed.

  That is, if the wall-integrated foundation block A of the present invention is installed and fixed at the end of the retaining wall W forming site, the small-sized retaining wall comprising the partition forming wall 4 and the wall member 5 at the end of the retaining wall W 6 can be formed, and if the wall-integrated foundation block A is installed and fixed at a predetermined partition position (position between the retaining walls W constructed in an adjacent state at a predetermined interval) at the retaining wall formation site, the adjacent retaining wall A partition wall 7 composed of the partition forming wall portion 4 and the wall member 5 can be formed between W.

  The wall-integrated foundation block A of the present invention can be easily realized by integrally forming the partition forming wall 4 on the bottom plate 3.

  In addition, for example, the partition forming wall portion 4 that rises upward is integrally formed at one of the left and right end portions of the bottom plate portion 3, and the height dimension of the partition forming wall portion 4 is set to the center of gravity of the block body 2. If the height dimension is set in the bottom plate portion 3 instead of the partition forming wall portion 4, the bottom plate portion 3 is present only on one side of the partition forming wall portion 4. In addition to the configuration suitable for the partition wall 7, it can also be used for forming the partition wall 7, and has the partition forming wall portion 4 at one end of the bottom plate portion 3. Since the center of gravity exists in the bottom plate part 3, it is hard to fall down and is excellent in safety.

  Further, for example, if a locking portion 8 that locks to the lower portion of the wall member 5 is provided at the upper portion of the partition forming wall portion 4, the locking portion 8 is locked to the lower portion of the wall member 5 to partition. It is possible to stack and install the wall member 5 on the upper portion of the forming wall portion 4 in a stable state that is difficult to be displaced.

  Further, for example, a wall-integrated foundation block A that is installed in a side-by-side arrangement with a concrete retaining wall foundation block 9 on which a stacking block 1 for constructing a retaining wall W can be loaded, If a connecting portion 10 that can be connected to the retaining wall foundation block 9 having a different front-rear width from the bottom plate portion 3 is provided at one of the left and right ends or both ends, the existing retaining wall foundation block 9 is Although the front-rear width dimension differs depending on the manufacturer, even the existing retaining wall foundation block 9 having a different front-rear width dimension can be connected via the connecting portion 10.

  Further, for example, if the rear end of the partition forming wall 4 has a structure in which an insert nut 13 that can be screwed with the screw rod 11 protruding rearward is embedded, the partition forming wall 4 (small stop wall) 6 or the partition wall 7) and the slope 20 are filled with a hardening agent 27 such as concrete and cured to integrate the partition wall 4 with the slope 20, the rear part of the partition wall 4 When the threaded rod 11 is screwed onto the insert nut 13 and the threaded rod 11 projects from the rear part of the partition forming wall 4, the threaded rod 11 functions as a reinforcing bar, and the partition forming wall 4, the curing agent 27, Can be firmly integrated.

  For example, if the insert nut 13 into which the screw 12 for fixing the mold member 14 can be screwed is embedded in the side wall portion of the partition forming wall portion 4, the partition forming wall portion 4 (small edge stopper) When the partition forming wall 4 is integrated with the slope 20 by filling a hardening agent 27 such as concrete between the wall 6 or the partition wall 7) and the slope 20 and hardening it, the partition forming wall 4 The mold material 14 for filling the curing agent 27 can be screwed 12 using the insert nut 13 on the side wall.
