[Action]

[Waterproof block wall according to claim 1] The waterproof block wall according to claim 1 is arranged around an underground portion such as a basement in a building. Water in the soil enters the concrete block on the soil side of each block body toward the building side, but there is a slight gap between the pair of concrete blocks in each block body, so Water that has entered the concrete block falls downward in the gap. That is, water does not enter the concrete block on the building side. In other words, the water that has penetrated into each block body from the soil is blocked by the gaps between the concrete blocks, so that the water does not reach the building. The spacer fitted in the gap between the concrete blocks serves to keep the gap between the concrete blocks constant. The pair of concrete blocks are provided with vertical ridges corresponding to the opposing surfaces, and these ridges are fitted together,
The pair of concrete blocks will not shift laterally.

[Waterproof Block Wall of Claim 2] The spacer in the waterproof block wall of claim 2 is a tile. The tile has sufficient strength as a spacer and can be obtained at low cost.

[Waterproof block wall according to claim 3] In the waterproof block wall according to claim 3, the gap between the concrete blocks has a taper shape that narrows downward, and the spacer is downward corresponding to the gap. Since the taper shape becomes narrower toward the side, the spacer completely adheres to the gap between the concrete blocks.

[Waterproof block wall according to claim 4] In the waterproof block wall according to claim 4, since the upper surface of the spacer is inclined so that the building side is higher, water falling on the spacer from the gap between the concrete blocks is prevented. Flow toward the concrete block on the soil side without going to the building side,
Along the concrete block on the soil side, further drop through the gap between the concrete blocks. Therefore, water does not reach the concrete block on the building side through the spacer fitted in the gap between the concrete blocks.

[Waterproof block wall of claim 5] In the waterproof block wall of claim 5, when stacking blocks, the soil side end of the building side connecting member is engaged with the building side end of the soil side connecting member. By stopping, the concrete block on the soil side and the concrete block on the building side are fixed to each other. After pouring concrete on the building side, the soil side end of the building side connecting member is removed from the building side end of the soil side connecting member, and the building side connecting member is removed (see FIG. 5). After that, only the soil side connecting member remains on the soil side concrete block. Thus, the building-side end of the soil-side connecting member is provided with a water stopper that closes the horizontal notch, and the water stopper prevents the water intruding along the horizontal notch in the soil-side concrete block. Preventing entry into vertical notch. As a result, water is prevented from entering the building even if the concrete block has a horizontal cutout.

[0021]

As described above, in the waterproof block wall according to the present invention, a pair of concrete blocks provided with vertical ridges corresponding to each other on opposite surfaces are fitted to each other with a slight gap. Along with that, a large number of block bodies in which spacers are fitted in the gaps between the concrete blocks are stacked, and since it is not necessary to place concrete between the concrete blocks, the work is simple and the construction period is greatly increased. It is possible to significantly reduce the construction cost as well as the construction cost. In addition, since a pair of concrete blocks are fitted together with a slight gap left between them and the water that has entered the concrete blocks from the soil side is allowed to fall into the gaps, water will not enter the building. In addition to being completely prevented, each concrete block can be much thinner than the concrete blocks used in conventional waterproof block walls. Therefore, the preferable effect that the manufacturing cost of the concrete block itself is also reduced is exhibited.
