Description

  The present invention relates to a curb-integrated side groove block in which a curb block and a side groove block arranged at the end of a road or a boundary between a roadway and a sidewalk are integrated, and a method for manufacturing the same.

  A curb block is provided at the end of the road or at the boundary between the roadway and the sidewalk to ensure the safety of pedestrians. When a gutter block as a rainwater drainage facility is provided at the end of the road, the curb block is constructed in a state of being partially mounted on the gutter block (see, for example, Patent Document 1).

FIG. 16 is a process diagram showing a construction procedure for a conventional curb block and gutter block.
First, as shown in FIG. 16 (a), the asphalt layer 30 and the ground layer 31 at the end of the road are excavated to form grooves 32 as shown in FIG. 16 (b), and as shown in FIG. 16 (c). The base 33 of the gutter block is formed with calcite and mortar. Then, as shown in FIG. 4D, a side groove block 34 is disposed on the foundation 33, and the backfilling material 35 is backfilled in the roadway side groove 32 as shown in FIG.

  Further, as shown in FIG. 5 (f), the backfilling material 35 is backfilled in the sidewalk-side groove 32, and as shown in FIG. 4 (g), curbstone and mortar are used to form a curbstone. Form the foundation 36 of the block. Further, a curb block 37 is disposed on the notch of the foundation 36 and the side groove block 34 as shown in FIG. 11 (h), and backfilling beside the curb block 37 as shown in FIG. The material 38 is backfilled. Finally, an asphalt layer 39 is formed on the backfill material 38.

  In the conventional construction method, it is necessary to perform excavation according to the width of the foundation 33 of the side groove block 34 and the width of the foundation 36 of the curb block 37 to be constructed in a state of being partially mounted on the notch of the side groove block 34. Because there is a large amount of excavation. In addition, since the side groove block 34 is disposed, backfilling is performed halfway, and the foundation 36 of the curb block 37 is formed. After the curb block 37 is disposed, the backfill is performed, so that workability is poor. Furthermore, since the curb block 37 and the side groove block 34 must be manufactured, the mold investment is large and the workability at the time of manufacture is also poor.

  In order to solve these problems, a side groove block in which a curb block and a side groove block are integrated has been developed. For example, the side groove blocks described in Patent Documents 2 and 3 are obtained by integrally molding a curb block at the time of molding the side groove block.

  By the way, when a house, a store, or the like is made along the road in the future, the vehicle cannot get over the step of the curb block on the side of the road, so a vehicle entry part that eliminates the step is necessary.

  At this time, as described in Patent Document 1, for curb blocks and gutter blocks manufactured and constructed separately, it is only necessary to replace the curb block. You have to start over. In addition, as described in Patent Documents 2 and 3, in the case of a side groove block integrated with a curb block, only the curb block portion cannot be separated, so the entire side groove block must be replaced, and the product cost and construction Both efforts are uneconomical.

  Therefore, in the present invention, in the curb integrated side groove block in which the curb block and the side groove block are integrated, a curb integrated side groove block capable of easily separating only the curb block portion and a manufacturing method thereof are provided. With the goal.

  The curb-integrated side groove block of the present invention is a curb-integrated side groove block in which the curb block and the side groove block are integrated, and a separation member is embedded in a boundary portion between the curb block part and the side groove block part. This is a curb integrated gutter block.

  Further, according to the manufacturing method of the curb-integrated side groove block of the present invention, a separating member is disposed in a part that becomes a boundary between the curb block part and the side groove block part in the mold, and the ready-mixed concrete is placed in the mold. It is characterized by being cast and molded.

  In another curb integrated side groove block of the present invention, a separation cavity is formed at the boundary between the curb block portion and the side groove block portion, instead of the separation member. This curb-integrated side groove block is provided with a die for forming a cavity for separation at the boundary between the curb block part and the side groove block part in the formwork, and pouring the ready-mixed concrete into the formwork. Mold with.
