Description

[Detailed description of the invention] The present invention allows for easy adjustment of the length of the body pipe according to the installation depth of the drainage basin, eliminates waste of body pipe material, and is economical in transportation. This is related to the construction of a drainage basin.

Drainage pipes are often buried underground, and the flow condition of the drainpipe is inspected, and if it is clogged with foreign matter, etc., there are measures to clean and remove it. Drainage drains are provided at appropriate intervals.

There are two types of drainage basins, one is an integrated type and the other is an assembled type, but the assembled type is preferred because it can accommodate the buried depth of the drainage pipe, and its structure is generally based on an inverted base (hereinafter referred to as inverted). The body pipes are stacked on top of each other and a lid is placed on top.
A typical example of its structure is shown in Figure 1 (right hemisection front view).
As shown below. That is, 1 is an invert, 2 is a body pipe, and 3 is a lid. The invert 1 is an open top container having two or more joint ports 4 on the side wall, and by connecting a drain pipe 5 to the joint ports 4. It forms part of the drainage channel. An annular groove 6 is formed at the upper end of the side wall of the invert 1, and the lower end peripheral edge 7 of the trunk tube 2 is fitted into the groove 6 via an adhesive. The illustrated trunk tube 2 has its lower end peripheral edge 7 slightly thicker than the wall main body to prevent breakage due to impact during handling. Also, an annular groove 6 is provided at the upper end peripheral edge of the trunk tube 2.
A is formed, and a lid 3 is attached to the groove 6a to form a drainage basin.

By the way, when burying the drainage basin like the one above, please make sure to match the depth to which the water pipes are buried.
The vertical length of the drainage basin must be adjusted, but this adjustment was done by selecting the optimal one from a variety of body pipes of different lengths, or by combining multiple shorter ones. . However, if the buried depth of the water pipe does not match the length of a single or combined trunk pipe, the plurality of annular protrusions 8 provided on the outer circumferential surface of the lower part of the trunk pipe 2 are used as a guide along the lower surface of the trunk pipe. It was necessary to cut the tube and adjust the length.
In other words, with conventional assembled drainage basins, it is necessary to transport and store a large number of extra trunk pipes at the construction site, and to take them home after construction is completed, making inventory management and transportation management extremely troublesome. If the actual burial depth was deeper than expected without preparation, the user would have to return home to retrieve the parts, which, despite the seeming convenience of an assembled structure, resulted in various inconveniences. In addition, the separated portion of the trunk pipe is wasted in terms of material, which not only increases material costs, but also requires temporary storage and transportation for disposal or reuse of the cut portion, which is not free. The flaw was that it made the construction work in this field, which requires a lot of cutting and cutting, even more complicated.

The present invention was developed in view of this situation, and the purpose is to provide an assembled drainage basin that is easy to adjust the height when assembling the drainage basin and that does not waste the material of the basin. It is something to do.
However, the assembled drainage basin of the present invention takes into consideration the formation of the body pipe, and a pair of fitting structures are formed on both ear sides of a flexible strip material, and the strip material is twisted into a spiral shape. A spirally wound body tube is formed by fitting the ear portions facing each other while winding in a shape, and a step structure is provided inside the upper part of the base portion to fit with a step at the lower end of the spirally wound body tube. An annular frame member having an upward socket shape and a downward socket and a receiving edge of the lid, and a step structure that fits with the step at the upper end of the spirally wound trunk pipe is provided between the trunk pipe and the lid. The key point lies in the intervention of

Hereinafter, embodiments of the present invention will be described based on the drawings, but the present invention is not limited to such embodiments. Appropriate design changes and the like are all included in the scope of the present invention.

FIGS. 2a to 2d are perspective views or partially cutaway views showing each component of the assembled drainage basin according to the present invention. 3 is a lid, 9 is an annular frame member, 2a is a winding trunk tube,
1a indicates an invert, and the assembly specifications thereof are approximately the same as those of the conventional example. However, an annular frame member 9 is placed on the upper peripheral edge of the body pipe 2a, and the lid 3 is fitted into the groove 9a of the frame member 9 to form a drainage basin. As shown in Figure 3 (right hemisection front view). In the drainage basin of the above embodiment, the main point of the present invention is the body part 2a.
is formed by spirally winding the strip material 10. FIG. 4 is an explanatory diagram of a combined state of the strip material 10, in which a fitting groove 11 continuous in the longitudinal direction is formed in one ear portion of the strip material 10, and the fitting groove 11 is formed in the other ear portion. A matching ridge 12 is also formed continuously and made of a flexible plastic material, such as polyethylene, polypropylene, polyvinyl chloride, or the like. Therefore, in forming the body tube, it is sufficient to wind the strips 10 to a desired diameter and stack them while fitting the protrusions 12 into the aforementioned fitting grooves 11. Step portions 10a and 10b are formed according to the width of the strip material 10, but the second
As shown in Figures b and d, stepped portions 10a and 1
Since the fitting recesses 9b, 1b are provided to match the shape of the step 10a, 10b, the fitting recesses 9b, 1b are provided to match the shape of the step 10a, 10b.
By fitting it into 1b, the body tube can be formed spirally without wasting the strip material.

FIG. 5 is an explanatory diagram of another combination of strip materials according to the present invention. One side of the strip material 10a is a smooth surface, and the other side has three protrusions 13, 1 along the longitudinal direction.
3a and 13b, and a fitting protrusion 14 having an S-shaped cross section, similar to the above-mentioned flexible plastic molded product, which fits into a recess 15 formed between the protrusions 13 and 13a. While fitting the protrusions 14, the belt-like material 10a is spirally wound and stacked with the smooth surface facing inside to form the body tube 2b. The reason why a plurality of protrusions 13, 13a, and 13b are formed is to reinforce the strip material, and sometimes only one protrusion is provided.

The strip material used in the drainage basin of the present invention needs to have flexibility as well as rigidity as a body pipe, and the thickness and width should be set according to the material. In addition, when storing and transporting the product, it can be rolled up into a coil so that it does not take up much space, is extremely convenient, and is economical in terms of transportation because it does not take up much space.

Since the present invention is structured as outlined above,
We were able to obtain the effects summarized below.

(1) Since the body pipe for the drainage basin is formed by winding a strip of material, the diameter and height of the body pipe can be freely selected. There is no longer a need to prepare a body pipe.

(2) The height of the body tube can be freely adjusted by cutting the strip material to a suitable length, making it easier to make fine adjustments that were considered difficult with conventional body tubes.

(3) In conventional body pipe height adjustment, a part of the body pipe that was cut during adjustment was discarded, but with the body pipe according to the present invention, the strip material is simply cut at right angles to the length direction of the strip. This allows us to form a trunk tube with the required diameter and height, eliminating material loss.
