Description

The present invention relates to a rooting block.

Conventionally, an embedding foundation block used for embedding a revetment has been disclosed for the purpose of preventing damage to the river revetment (see, for example, Patent Document 1).

The conventional embedding foundation block disclosed in Patent Document 1 integrally includes a main body portion made of a thick plate-shaped member and a support portion having a triangular side view that supports the main body portion in a slanted state.

Since the rear surface of the support portion is open in the recess of the conventional rooting foundation block, the workability of construction when filling the earth and sand is poor.

An object of the present invention is to provide a rooting block with improved construction workability.

The present invention is a rooting block laid to build the foundation of a block retaining wall, which is filled with a filler inside and provided with a filling space having an upper opening that opens upward. The front side plate is integrally provided with a main body, a front side plate-shaped portion that inclines toward the rear as it goes upward, and a rear side plate-shaped portion that is provided on the opposite side of the front side plate-shaped portion across the block main body. The shaped portion and the rear side plate-shaped portion are provided so as to project upward from the upper surface of the block main body, and the block retaining wall is installed on each upper surface of the front side plate-shaped portion and the rear side plate-shaped portion. The block retaining wall is laminated so as to be continuous with the front side plate-shaped portion, and the rear side plate-shaped portion is continuous with the lower plate-shaped portion and above the lower plate-shaped portion at a predetermined angle. The upper plate-shaped portion and the front side plate-shaped portion are formed so as to have substantially the same inclination angle with respect to the lower surface.

According to the present invention as described above, the embedding block has a filling space in which the filler is filled, and the filling space has an upper opening that opens upward in the installed state. .. According to this, in the installed state, for example, ready-mixed concrete as a filler can be injected into the filling space from the upper opening that opens upward, so that the construction workability can be improved.

Further, it has a substantially rectangular lower surface in a plan view and an inclined surface that is continuous with the front end of the lower surface and inclines toward the rear as it goes upward, and the lower surface is penetrated into the ground. A concave groove-shaped support recess into which the upper end of the sheet pile is fitted is provided, and the support recess is continuously formed in the left-right direction orthogonal to the front-rear direction of the lower surface, and the internal space of the support recess and the filling space. Is preferably formed so as to communicate with each other. According to this, by injecting ready-mixed concrete as a filler into the filling space from the upper opening that opens upward, the ready-mixed concrete flows into the internal space of the support recess. In this way, the sheet pile is integrated into the rooting block.

Further, a concave groove portion is provided on a side surface having a substantially rectangular lower surface in a plan view and rising from both ends in the left-right direction of the lower surface, and the concave groove portion has openings in the upward and left-right directions. It is preferable to have and be configured. According to this, in a state where a plurality of rooting blocks are provided side by side in the left-right direction, ready-mixed concrete as a filler is injected from the opening above the concave groove portion, so that the construction workability is good and the adjacent roots are adjacent. It is possible to strengthen the connection between the filling blocks.
