Conventionally, the contact material 1' is made by vacuum forming a calendered synthetic resin sheet with a thickness of about 0.3 to 0.6 mm, and bending the whole into a corrugated plate shape, and protruding protrusions 3' on both sides. A contact material block 4' was constructed by directly bonding the contact materials 1' to each other and connecting the contact materials 1' substantially parallel to each other, and a constant distance was secured between the contact materials 1' by the protrusions 3'. Therefore, if the distance between the contact members 1' is to be increased from that shown in FIG. 1a to that shown in FIG. 1b, it is necessary to increase the height of the protrusions 3'. However, since the contact material 1' is formed by vacuum forming, the protrusions 3' are thinner than the other parts, and if the protrusions 3' are made higher in order to increase the distance between the contact materials 1', they become too thin for practical use. There is a risk that it will disappear or a hole will be formed in the protrusion 3'. Therefore,
In order to effectively increase the height of the protrusions 3', it is necessary to make the base calender sheet thicker than before, which poses a problem of increasing the cost per sheet of contact material.

The present invention was made in view of the prior art described above, and its purpose is to ensure the strength of the protrusions even when the protrusions are made high to ensure the distance between the contact materials, and to ensure the strength of the protrusions. To provide a structure of a contact material block for a septic tank, which can keep the cost per block low.

What is shown in FIG. 2a is a calender sheet 5 made of vinyl chloride that serves as a base material, and linear thick portions 2 are provided at regular pitches. The thickness of the thick portion 2 is approximately 0.1 to 0.5 mm thicker than the thickness of the thin portion 6, and is approximately 0.2 to 0.7 mm. The contact material 1 is formed by subjecting the calender sheet 5 to vacuum forming and having truncated conical projections 3 protruding alternately from both sides of the thick portion 2. Therefore, even if the thickness of the protrusion 1 is reduced during vacuum forming, this portion does not become particularly weak, and the compressive strength of the protrusion 3 is ensured. A contact material block 4 is constructed by arranging a plurality of contact materials 1 in parallel and adhering the protrusions 3 of adjacent contact materials 1 to each other as shown in FIG. The contact material block 4 is installed between the partition plates 7 in the septic tank as shown in FIG.

Since the present invention is constructed as described above, when comparing contact materials (calendar sheets) of the same weight, the wall thickness of the boss can be increased, the thickness shrinkage strength of the boss can be improved, and the entire wall thickness can be increased. This has the effect that the cost of the veneer is not as high as in the case of using a base material.
