DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin drainage basin, and more particularly, to a synthetic resin drainage basin using ribbed high rigid pipes as an inflow pipe and an outflow pipe.

[0002]

2. Description of the Related Art In a series of sewage treatment functions of collecting wastewater from various places, guiding the wastewater to a wastewater treatment plant, and purifying and discharging the wastewater, smooth collection of the generated wastewater is the most important function. Various members including a drainage basin have been developed in order to measure the size of the basin. On the other hand, concrete products for drainage equipment including drainage pipes such as inflow pipes and outflow pipes have been used extensively in the past. Recently, the use of synthetic resin pipes and synthetic resin drainage basins has been increasing.

In particular, as the above-mentioned synthetic resin pipe, a so-called "high-rigid pipe with ribs" reinforced by a rib structure is used in new construction and repair work of sewage pipes. When connecting to the synthetic resin drainage basin, it is impossible to join it as it is, and even if it can be connected well, the outer diameter and the inner diameter of the rib pipe and the inflow pipe of the synthetic resin drainage basin connected thereto A step or a gap was formed between the receiving port and the outlet of the outlet pipe, which hindered the smooth drainage collection function of the drain pipe system.

Therefore, between the high-rigidity pipe with ribs and the drainage basin made of synthetic resin, an intermediate joint made of a special-diameter pipe joint is used so as to prevent a step at the connection portion. It is. However, in order to prepare the dedicated intermediate joints in various drainage lines, it is necessary to prepare enormous sizes and types of joints ranging from small diameter to large diameter. Since it is required to lay the inflow pipe and the outflow pipe in the drainage basin as compactly as possible because they are to be laid in limited places around the periphery of objects, etc. It could be difficult. Under such circumstances, the development of a drainage basin capable of providing a highly rigid pipe with ribs in a compact and highly efficient manner has been eagerly desired.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above facts, and an object of the present invention is to provide a drain line using a high-rigidity pipe with ribs as an inflow pipe and an outflow pipe. An object of the present invention is to provide a synthetic resin drainage basin that can be piped reliably and easily without using a special intermediate joint and without steps or gaps.

[0006]

According to the first aspect of the present invention,
A receiving port having an inner diameter substantially equal to the outer diameter of the plurality of annular ribs provided around the outer wall of the inflow pipe, and an inflow having a diameter substantially equal to the inner diameter of the inflow pipe connected to the receiving port and opened to the wall of the drainage basin body; A drainage basin body having a hole, an outflow hole and an outlet connected thereto, and an elastic ring fitted so that its tip slightly pops out between annular ribs near the inlet of the inflow pipe inserted into the receptacle. A synthetic resin drainage basin comprising a synthetic resin drainage basin characterized in that the difference between the outer diameter and the inner diameter of the elastic ring is continuously changed in the circumferential direction. I do.

The inflow pipe provided with a plurality of annular ribs around the outer wall connected to the synthetic resin drainage basin of the present invention is provided by providing a plurality of annular ribs on the outer wall of the synthetic resin pipe. It can increase the rigidity of the synthetic resin pipe and achieve high flat strength without increasing the thickness of the synthetic resin pipe, and can be used in all burial sites such as deep burial, ultra-shallow burial, burial under the roadway, etc. As a synthetic resin tube that can be used, recently, a synthetic resin tube newly developed, generally called a high-rigid tube with ribs and certified by the Japan Sewage Works Association, is used. means.

The shape of the annular rib is not particularly limited as long as it can enhance the rigidity of the synthetic resin pipe. For example, in the case of a synthetic resin pipe having a nominal diameter of 200 mm, the height is 11 mm. For a synthetic resin tube with a diameter of .6 mm, a width of 3.5 mm, a rib pitch of 25.4 mm and a nominal diameter of 200 mm,
Height 18.2 mm, width 5.5 mm, rib pitch 38.
For example, a rib having a dimension of 1 mm can be used. Further, the tip of the annular rib is not particularly limited, for example,
It may be one that forms a smooth surface like the outer peripheral edge of a disk, but it may also be one in which both outer peripheral edges at the above-mentioned tip are cut with a curved surface and formed into a middle-high mountain shape.

The high rigid pipe with ribs is not particularly limited in the material and the like of the synthetic resin constituting the ribs except for providing the rib structure. For example, hard vinyl chloride resin, polyethylene, polypropylene, etc. Olefin resins and the like can be mentioned. These ribbed high rigid pipes are
Like the hard vinyl chloride resin pipe, the pipe end can be expanded at the time of piping.

The shape of the receiving port in the synthetic resin drainage basin of the present invention is such that the inlet at one end of the high-rigidity pipe with the rib can be connected to the inner wall of the receiving port in a watertight manner. A cylindrical rib having an inner diameter substantially equal to the outer diameter of the annular rib, and at least two or more of the annular ribs provided on the outer wall of the inflow pipe have a length capable of being inserted into the receptacle. Although it may be a receiving port, the inner diameter gradually decreases in the insertion direction of the insertion port at one end of the inflow pipe, and a 2/3 length is inserted from the end face of the receiving port toward the inflow hole provided in the drainage basin body. May be a tapered sleeve-shaped receptacle having an inner diameter substantially equal to the outer diameter of the annular rib of the inflow pipe at the inclined position.

In the synthetic resin drainage basin of the present invention, the number of receptacles provided in the drainage basin body is not particularly limited. For example, only one location may be provided, but two or more locations may be provided. Is also good.

The elastic ring in the synthetic resin drainage basin of the present invention is fitted between two adjacent ribs near the inlet of the inflow pipe, and is inserted into the receiving port of the synthetic resin drainage tubing and piped. . Due to the elasticity of the elastic ring, the elastic ring is tightened so as not to be displaced from the position fitted at the time of the piping, and its tip is slightly protruded between the two adjacent ribs. It is fitted. The elastic ring fitted as described above has a slightly protruding tip that presses against the inner wall of the receiving port, so that the receiving port and the inflow pipe can be piped in a watertight manner. The difference in the inner diameter changes continuously in the circumferential direction.

The difference between the outer diameter and the inner diameter of the elastic ring is as follows.
In other words, although the height is high, the elastic ring is pressed by the annular rib during use and changes its height. The height in the cross-sectional shape of the elastic ring at the time is expressed by the difference between the outer diameter and the inner diameter as described above.

The method for setting the difference between the outer diameter and the inner diameter of the elastic ring is not particularly limited.
0 ° rotated each maximum value at a position (t _max.) And the minimum value (t _{mi n.)} And may be continuously changed such that,
Further, the degree of the above change may be given a gradual change, for example, by making the width of the maximum value (t _max. ) And the minimum value (t _min. ) Longer than other changing portions.

The outer diameter of the above-mentioned elastic ring is appropriately set for each nominal diameter of the inflow pipe to be used. (T _max. ) And the minimum value (t _min. ), T _max. = 21.6 mm for a 200 mm nominal diameter receptacle _.
In the case of a receptacle having a t _min. = 15.6 mm and a nominal diameter of 300 mm, t _max. = 28.2 mm and t _min. = 22.2 mm. These elastic rings are fitted so as to protrude by about 2 to 5 mm from the height of the annular rib of the drainage inflow pipe.

The number between the two adjacent annular ribs into which the elastic rings are fitted is not particularly limited. For example, the number may be one, but may be two or more. .

[0017] The material of the elastic ring can be fitted between the two adjacent ribs in the vicinity of the inlet of the inflow pipe so that it does not deviate from the fitted position at the time of piping. It is not particularly limited as long as the inner wall of the receiving port is pressed down and the receiving port and the inflow pipe can be piped in a watertight manner, for example, styrene butadiene rubber (SBR), chloroprene rubber ( CR), fluoro rubber, ethylene propylene rubber (EP
DM etc.).

The outlet of the drainage basin connected to the outlet is not particularly limited, and is appropriately formed depending on the type of the outlet pipe. For example, a cylindrical outlet having the same shape as a rigid polyvinyl chloride resin drain pipe is used. It may be a mouth, it may be a flange joining outlet provided with a flange at the tip, and further from a high-rigidity ribbed pipe having a plurality of annular ribs around the outer wall of the outflow pipe, like the inflow pipe. It may be.

According to a second aspect of the present invention, the outlet connected to the outlet is provided with two or more annular ribs having an outer diameter substantially equal to the inner diameter of the outlet of the outlet pipe around the outer wall. The gist of the present invention is a synthetic resin drainage basin according to claim 1, wherein an elastic body ring is fitted between the annular ribs so that the tip thereof protrudes slightly.

In the present invention, the annular rib provided annularly around the outer wall of the outlet connected to the outlet hole is fitted between two adjacent annular ribs so that the tip thereof slightly jumps out. The elastic ring can form a groove having a depth and a width that can be clamped to such a degree that the elastic ring does not deviate from the position where the ring is fitted when the outflow pipe is piped. The elastic ring protruding into the outlet pipe presses the inner surface of the outflow pipe, and is not particularly limited as long as it can pipe the outlet and the outflow pipe in a watertight manner. An annular rib having the same shape and the same size as the above-mentioned rib of the high-rigidity pipe is used.

The number of the annular ribs may be two, but may be two or more. The elastic ring is fitted between the two annular ribs, and the tip of the elastic ring slightly protrudes from the tip of the annular rib so that the outlet and the outflow pipe can be connected in a watertight manner. If so, an elastic ring in which the difference between the outer diameter and the inner diameter does not change is preferably used, unlike the above-mentioned socket. Also, the number of elastic rings fitted between the two annular ribs is not particularly limited,
For example, the number may be one, but may be two or more.

Since the synthetic resin drainage basin according to the first aspect is constructed as described above, the inflow pipe made of a high-rigidity pipe with a rib is sprayed on the receiving port, and the lubricant is sprayed on the surface of the elastic ring as required. Then, just by inserting, the pipe can be extremely easily and reliably piped. Therefore, as compared with the conventional piping method using an intermediate joint dedicated to a high-rigidity pipe with ribs, the number of members used and the number of construction steps can be significantly reduced, and the seismic performance of the joint can be improved. it can.

Further, even if the inner diameter of the ribbed high-rigidity pipe is not uniform and the inner bottom face of the inflow pipe formed of the ribbed high-rigidity pipe and the inner bottom face of the receiving port are not flush with each other, the ribbed high-rigidity pipe may be used. If the outer diameter of the high-rigidity pipe is slightly smaller,
The part where the difference between the outer diameter and the inner diameter of the elastic ring is the maximum value is located on the bottom, and if the outer diameter of the ribbed high-rigidity pipe is slightly larger, the outer diameter of the elastic ring is By piping such that the part with the smallest difference in inner diameter comes to the bottom surface, the ribs of the high-rigid pipe with ribs inserted into the receptacle are partially deformed, etc. Since the inner bottom surface and the inner bottom surface of the receptacle are adjusted flush,
There is no possibility that the solid matter in the drainage stays on the step generated at the connection part, and a smooth drainage flow can be formed.

Since the drainage basin made of synthetic resin according to the second aspect is constructed as described above, it is extremely easy only by inserting a discharge pipe made of a high-rigidity pipe with ribs into the receptacle as well as the receptacle. In addition, piping can be reliably performed. Therefore, the drainage line can be laid in a compact piping space even in a place where the periphery of the building is limited.
