Description

[Detailed description of the invention] This invention relates to a manhole collection basin that collects inflowing sewage and discharges it to a designated drainage channel. The present invention relates to a water collection basin for a manhole that easily stabilizes and fixes the connection positions of the inflow pipe and drainage pipe connected to the hole, and speeds up the connection of the inflow pipe and drainage pipe to the water collection basin.

Conventionally, manholes were laid by pouring on-site for the lower part of the manhole, but due to current road traffic conditions, in order to meet the requirement of completing backfilling in a short construction period, the above-mentioned manhole It was also necessary to use a factory-molded catchment for the lower catchment to shorten construction time.

However, in the case of manholes, the inflow pipes and drainage pipes connected to them have large diameters and are heavy, so when connecting the inflow pipes and drainage pipes to the insertion holes formed in the water collection basin, it is necessary to make sure that the inflow pipes, etc. It has been difficult to quickly and reliably secure a suitable connection position.

Therefore, the present invention aims to provide a water collection basin for a manhole that eliminates the above-mentioned drawbacks by forming a mounting table for an inflow pipe or the like in the water collection basin.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Reference numeral 1 is a water collection basin body, and a collection chamber 2 in which waste water is collected is provided inside. 3 indicates the bottom formed at the lower part of the gathering chamber 2.

Reference numeral 5 denotes a plurality of thin wall portions provided on the peripheral wall 6 of the gathering room 2. This thin wall portion 5 is for opening an insertion hole for connecting an inflow pipe and a drain pipe to the water collection basin main body 1, and is formed to be thin in order to facilitate crushing. are doing. In addition, in the embodiment, this thin walled portion 5 is formed into three circular thin walled portions 5a, 5b, and 5b with different diameters, as shown in FIG.
5c, and these three circular thin parts 5a,
The circumferential outlines 5A, 5B, and 5C of 5b and 5c are inscribed at the lowest point P of the large-diameter circular thin-walled portion 5a. The lowest point P of this thin-walled portion 5 is such that the thin-walled portion 5 for the inflow pipe and the thin-walled portion 5 for the drain pipe have different heights from the bottom surface 7 of the collection chamber 2, and the thin-walled portion 5 for the inflow pipe The lowest point P ₁ of the drain pipe 5 is located above the lowest point P ₂ of the thin wall portion 5 for the drain pipe.

Reference numeral 8 denotes a mounting table portion whose upper end surface 9 is in contact with the lowest point P of the thin wall portion 5 and is formed as a perpendicular surface to the thin wall portion 5, and is provided on the outer surface of the peripheral wall 6 of the advancement chamber 2. There is. The upper end surface 9 of this mounting table part 8 has a large diameter among the circular thin parts 5a, 5b, 5c because the thin part 5 has three circular thin parts 5a, 5b, 5c with different diameters as described above. Circular thin wall part 5 of
It is formed so as to be circumscribed around the lowest point P with the circumferential outline 5A of a. In addition, as mentioned above, since the lowest point P of the thin wall portion 5 is located at a different position depending on whether it is for an inflow pipe or a drain pipe, the upper end surface 9 of the mounting table 8 is also suitable for an inflow pipe rather than a drain pipe. It is formed at a higher position.

In the above configuration, when connecting the inflow pipe and the drainage pipe to the water collection basin main body 1, the three circular thin-walled parts 5a, 5b, and 5c are appropriately selected according to the pipe diameter, and the parts are crushed and inserted. A hole is formed, and the insertion end of the inflow pipe or drain pipe is placed on the upper end surface 9 of the mounting table 8, and the inflow pipe or drain pipe is connected to the insertion hole.

As described above, in the present invention, the lowest point P of the thin wall portion 5
A mounting table portion 8 having an upper end surface 9 in contact with the upper end surface 9 and the upper end surface 9 being formed as a perpendicular surface to the thin wall portion 5.
is provided on the outer surface of the peripheral wall 6 of the collection chamber 2, so that when connecting an inflow pipe or a drainage pipe to the insertion hole of the water collection basin main body 1, as described above, the insertion end of the inflow pipe or drainage pipe can be placed on the upper end surface 9 of the mounting table 8 and connected.

Therefore, it is possible to connect large-diameter manhole inflow pipes and drainage pipes to the insertion holes of the water collection basin body 1 while maintaining appropriate positions.

In addition, since the position of the inflow pipe and drain pipe connected to the insertion hole of the water collection basin body 1 can be maintained properly and stably, the position of the inflow pipe and drain pipe connected to the insertion hole can be In order to maintain the located inflow pipe and drain pipe in a horizontal position with the insertion hole, there is no need to measure and install the inflow pipe again by connecting it to the rear according to the laying position of the connecting inflow pipe and drain pipe. and drainage pipes can be laid quickly and in appropriate positions.
