  In a conventional drainage wastewater treatment device, the wastewater guided and introduced from the drainage pipe through the inflow guide to the drainage groove of the groove forming floor material flows while diffusing throughout the width of the drainage groove. The average water level in the water becomes shallow, and the drainage performance is reduced due to a decrease in the water pressure of the drainage, and impurities such as dust in the drainage easily collect.

  In addition, the wastewater guided and introduced into the drainage groove of the groove-forming floor material flows while diffusing throughout the width of the drainage groove, so that the drainage easily freezes in layers in winter.

  Therefore, when the drainage groove is clogged due to accumulation of impurities or freezing of the wastewater as described above, there is a disadvantage that the wastewater leaks to the outside of the groove-forming floor material.

  In addition, as a method for solving such inconvenience, for example, as shown in Patent Document 3, at one or a plurality of locations in the width direction on the bottom surface of the drainage groove of the groove forming floor material, a small width that is one step deeper than the drainage groove. There has been proposed a method of forming a groove or forming a bottom surface of a drainage groove of a groove-forming floor material in a V shape in a cross-sectional view to ensure water pressure depending on the amount of water and water depth.

  Even in this case, if impurities accumulate in the narrow groove on the bottom of the drainage groove or the V-shaped drainage groove, or the drainage freezes in layers, the drainage flows while diffusing to the entire width of the drainage groove. Similar to the above, there is a problem in that the drainage performance is degraded or the drainage clogging is caused by the accumulation of impurities.

  In addition, since the groove forming floor material is generally used by being fixed to the floor surface with an adhesive or the like, the mounting position of the fixed groove forming floor material and the attachment of the drain pipe led out from the drain waste water generating equipment side At the construction site where the position is displaced in the groove width direction, if the drain pipe is a pipe with a small amount of bending deformation such as a hard vinyl chloride pipe, the drain pipe is fitted to the groove forming floor material A situation occurs in which the inflow guide tube of the held inflow guide cannot be connected. In this case, it is necessary to replace the drain pipe with a pipe having a large amount of bending deformation such as a stainless steel flexible pipe, and it is easy to make the construction complicated and increase the construction cost in the future.

  The present invention has been made in view of the above-mentioned actual situation, and its main problem is that it is possible to improve drainage performance and to prevent contamination by rational improvement of the drainage groove and the inflow guide of the groove forming floor material. It is possible to suppress accumulation and facilitate the cleaning of the groove of the groove forming floor material, and also easily cope with the case where the mounting position of the groove forming floor material and the mounting position of the drain pipe are misaligned in the groove width direction. It is in the point which provides the drain waste water treatment apparatus which can be performed to.

  According to a first characteristic configuration of the present invention, a groove forming floor material in which a drain drainage groove is formed is provided with a partition portion that partitions the drainage groove into a plurality of drainage groove portions in the width direction, and the groove formation is performed. The mounting base material detachable from the flooring includes an inflow guide for guiding the drainage from the drain drain pipe into one of the plurality of drainage grooves, and a drainage position of the inflow guide for the drainage. A drainage position changing means for changing in the width direction of the groove is provided.

  According to the above configuration, by selecting one drainage position of the inflow guide tool from among the plurality of drainage grooves, the average water level in the width direction of one drainage groove is greater than when using the entire drainage groove. The wastewater that has become deeper and flows into the drainage groove can be smoothly discharged by increasing the amount of water and the water pressure, and it is possible to suppress the accumulation of impurities in the wastewater.

  Moreover, even if the mounting position of the groove forming floor material fixed to the floor surface with an adhesive or the like and the mounting position of the drain pipe led out from the drain drainage generator side are displaced in the groove width direction, the drainage position changing means Therefore, the displacement can be absorbed by changing the drainage position of the inflow guide in the groove width direction.

  Also, when cleaning the groove forming floor material, the drainage position changing means changes the drainage position of the inflow guide from the drainage groove part in use to the unused drainage groove part, while continuing to drain the drainage drainage. The used drainage groove can be cleaned.

  Therefore, it is possible to improve drainage performance, suppress accumulation of contaminants and facilitate groove cleaning of the groove forming floor material, and the groove forming floor material mounting position and the drain pipe mounting position are in the groove width direction. It is possible to easily cope with the case where the position is shifted.

  According to a second characteristic configuration of the present invention, when the water level of the drainage in the drainage channel reaches a set water level, the drainage in the drainage channel overflows the other drainage channel adjacent to the upper part of the partition. It is in the point which is made to be made to constitute.

  According to the above configuration, even when the drainage groove part in use is clogged with impurities or when clogging occurs due to freezing of the drainage, the wastewater in the drainage groove part in use is partitioned on the upstream side of the clogged part. Since it can be made to overflow smoothly to the other drainage groove part which passes the upper part of a part and adjoins, it can suppress that drainage leaks outside the groove | channel formation flooring.

  Furthermore, even if the amount of drainage water that is guided to the drainage channel in use temporarily increases beyond the drainage capacity of the drainage channel, the drainage in this drainage channel passes adjacent to the upper part of the partition. Since it can be made to overflow smoothly to the other drainage groove part to perform, it can also suppress that the waste_water | drain which increased temporarily temporarily leaks outside the groove | channel formation floor material.

  Therefore, when the clogging of the drainage groove due to the accumulation or freezing of impurities occurs and when the drainage temporarily increases, it is possible to automatically deal with it.

  According to a third characteristic configuration of the present invention, when the drainage position changing means is configured, the mounting base material is mounted in a state in which the longitudinal direction in the groove longitudinal direction can be changed with respect to the groove forming floor material. And a holding portion that detachably holds the inflow guide in a state in which the front-rear direction in the groove longitudinal direction can be changed at a portion displaced to one side in the groove width direction of the mounting base. There is in point.

  According to the above configuration, when it is necessary to change the drainage position of the inflow guide, the reverse mounting operation of the mounting base material in the front-rear direction with respect to the groove-forming floor material, and one side of the mounting base material in the groove width direction Therefore, it is only necessary to perform the reverse mounting operation of the inflow guide tool in the front-rear direction with respect to the holding portion at the position displaced in the direction, facilitating the drainage position changing operation and simplifying the structure of the drainage position changing means.

  According to a fourth characteristic configuration of the present invention, the attachment base material includes a fitting portion that is detachably fitted to a fitted portion formed on a side wall portion on both sides in the width direction of the groove-formed floor material. When the fitting portion is fitted to the fitted portion, a weir portion is formed that contacts the inner surface of the groove-forming floor material and blocks the drain groove in the width direction. .

  According to the above configuration, when the fitting portion of the mounting base material is fitted to the fitted portion of the groove forming floor material, the weir portion formed on the mounting base material contacts the inner surface of the groove forming floor material. Thus, since the drainage groove is blocked in the width direction, it is possible to prevent the drainage guided to flow into the one drainage groove from the inflow guide to flow backward to the upstream side.

  According to a fifth characteristic configuration of the present invention, an engagement portion provided at a portion where the holding portion is displaced to one side in the width direction of the mounting base, and a groove with respect to the engagement portion. The engagement portion provided on the inflow guide is engageable from the longitudinal direction, and the engagement portion is engaged with the engaged portion from the longitudinal direction of the groove. This is in that a position restricting portion for restricting to the engagement depth position is provided.

  According to the above configuration, when the inflow guide is reversely mounted to the holding portion of the mounting base, the inflow guide side is engaged with the engaged portion on the mounting base that constitutes the holding portion. The engagement portion of the inflow guide can be reliably mounted at the set engagement depth position simply by engaging the portion from the longitudinal direction of the groove to the position restricted by the position restriction portion.
