- the whole is surrounded and closed by concrete wall 9.
- the part facing the ground should be equipped with an appropriate cover or an openable lid.
- each block 3 has a hollow structure in which the inside is a hollow portion 3a, and the hollow portions 3a of all the blocks 3 communicate with each other by an opening 3b on the peripheral surface. Then, a gap is formed around each block 3 by the joint 1 including the spacers 8a and 8b. Therefore, the entire city surrounded by the concrete wall 9 becomes a tank with the block 3 interposed and can be used as a reservoir. Since the blocks 3 are arranged in a grid in the concrete wall 9, they function as a reinforcing material, and the measures against earthquakes and the like are also thorough. It should be noted that it is not possible to use the illustrated structure itself as a water storage tank to be installed on the ground or on the rooftop of a building, etc. instead of using it as a groundwater tank.
- FIG. 21 is a schematic cross-sectional view of another example of a structure that can be used as a groundwater tank.
- the block 10 shown in FIG. (Same as the joint 2) are arranged vertically and horizontally in the horizontal direction and stacked vertically, and a water-permeable collection is placed on the structure 21 of these blocks 10.
- Water department 17 is provided.
- a space 19 where no block is arranged is formed in a part of the structure 21 of the block 10, and a manhole 18 is provided above the space 19.
- each block 10 has a cubic shape and is self-supporting, is easy to construct, can be arranged and stacked in an orderly manner, and has good stability.
- the block 10 since the block 10 has a hollow portion 11 communicating with all six sides, it can store a large amount of water, is relatively lightweight and has good workability, and there is a possibility that land subsidence may occur. Absent.
- the blocks 10 are cubic, the same state can be obtained even if they are arranged and stacked with any surface facing upward, and the arrangement and the eyebrows suitable for the lightning space at the construction site can be performed.
- blocks can be deposited in the receiving seat formed in the joint and these blocks can be arranged and laminated with a gap, so that the conventional joint for forming joints can be used.
- the joint functions as a positioning material for each block, which simplifies the work and provides a stable work body with a regular arrangement of blocks after the work.
- the mortar or the like can be supplied to the surface of the receiving seat of the joint. This eliminates the need for a step of applying, and improves workability.
- each joint can be chained with each other by passing a tension material such as a wire through these through holes, so that the entire block is restrained through the joint.
- a tension material such as a wire
- the lock itself has a hollow structure and This allows a gap to be provided between the blocks, thereby increasing the overall porosity of the block structure. Therefore, the size of the block structure can be reduced, and the adaptation to soft ground can be optimized.
- the present invention can be applied to fields such as a concrete material constructed by using a block joint to be used as a core material such as a lightweight embankment, or an underground buried type water tank or the like due to a communication structure between concrete blocks.
