Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water collecting basin device which is buried in a proper place at a side end of a road and used for draining wastewater such as rainwater.

[0002]

2. Description of the Related Art FIG. 4 is a sectional view showing a conventional water collecting and collecting device. This water collecting basin device has a cylindrical rigid synthetic resin basin body 71 whose diameter is enlarged upward from the bottom surface, and is detachably attached to the bottom surface of the basin body 71 and has a diameter larger than the outer diameter of the basin body 71. Prevention ring-shaped collar plate 7 having an outer diameter of
4 A plurality of cutouts are provided at appropriate positions on the inner peripheral edge of the window of the ring-shaped collar plate 74. On the other hand, on the bottom surface 72 of the box main body 71, there is a slotted protrusion stopping portion 7 protruding outward in a proper position.
A plurality of 3 are projected. The ring-shaped collar plate 74 is made to correspond to the notch portion of the ring-shaped collar plate 74 with the protrusion stop portion, and the ring-shaped collar plate 74 is attached to the main body 71.
To the bottom surface 72 of the. In this state, the ring-shaped collar plate 7
4 is rotated so that the inner peripheral edge of the hole of the ring-shaped collar plate 74 is fitted into the groove hole of the protrusion stopping portion 73 to be fixed. Further, a through hole 75 for connecting the pipe 76 is formed in the peripheral wall of the box main body 71.

At the time of burying on the road side edge, the box main body 71
Open a pilot hole to embed. The box main body 71 is fitted into the prepared hole, and the end of the pipe 76 is fitted into the through hole 75. After this, the earth and sand A at the time of opening the pilot hole is filled into the fitting gap between the pilot hole and the box main body (including the ring-shaped collar plate and the pipe) 71. Therefore, in this water collecting basin device, by attaching a ring-shaped collar plate having a diameter larger than that of the basin body to the basin body, the weight of the earth and sand to be filled acts on the ring-shaped collar plate, and the earth pressure Masu body is pressed downward. Therefore, as compared with the case main body having no ring-shaped collar plate, there is a temporary floating prevention effect.

[0004]

SUMMARY OF THE INVENTION In the above-mentioned conventional water collecting basin device, the basin body is simply fitted and arranged in the prepared hole.
When the earth and sand are thrown into the fitting gap, the pressure of the thrown earth and sand may cause the square body (including the ring-shaped collar plate) to be displaced. Further, the earth and sand to be filled are aggregates having various diameters such as fine sand, fine stones, and small stones, and even if the filled earth and sand are clamped, the weight density acting on the ring-shaped collar plate is small. Therefore, the soil pressure that presses the box body downward is small, and there is a possibility that the box body will float up due to vibration applied to the road.

Further, the cylindrical main body made of synthetic resin is formed in a taper shape expanding upward from the bottom surface. Therefore, a special hole drilling tool is required to open a through hole connecting a pipe in a perfect circular shape.

Further, the synthetic resin container body is set to have a thickness as thin as possible in order to reduce the weight. Therefore, in the structure in which the long and heavy pipe end is directly supported by the box main body, there is a defect that the box main body is distorted.

Further, in the conventional water collecting basin device, the end of the pipe is fitted into the through hole. Therefore, the end of the pipe projects into the internal space of the box body. Therefore, when removing the sludge settling on the bottom of the water collecting basin, the vacuum hose collides with the projecting end of the pipe, which hinders the hose from being taken in and out.

Further, in this water collecting basin, a large-diameter ring-shaped collar plate projects around the outer circumference of the main body of the basin. Therefore, it is necessary to open a large pilot hole on the road surface. The water collecting basin is installed at the boundary between the road surface and the sidewalk. There is a shoulder block at this boundary. Therefore, when opening a large pilot hole, this shoulder block must also be destroyed,
There was a disadvantage that the work was troublesome.

The present invention solves the problems as described above, and when pouring and filling earth and sand into the fitting gap between the cell body and the prepared hole, the cell body does not shift its position and the cell body is completely lifted. It is an object of the present invention to provide a water collecting basin device which is capable of preventing the above-mentioned problems and which is capable of causing the weight of the supporting pipe to act on the basin body as a pressing force and which is excellent in installation stability.

[0010]

In order to achieve this object, the water collecting basin device of the present invention has the following structure. The water collecting basin device is inserted into the rectangular cylindrical box body made of synthetic resin with an upper opening and a bottom, and the through holes in both wall surfaces facing each other of this basin body, and the thin plate-like collar plate is adhered to the inner wall surface of the box body. In addition, a pipe joint in which a continuous cylindrical portion that is continuous with the collar plate is internally fitted to the pipe, a protruding flange plate that continuously projects from both end portions of the bottom surface of the box body, and this protruding flange plate is provided.
It is characterized in that the bottom surface is in contact with the upper surface of the projecting flange plate, and the upper surface is in contact with the bottom surface of the pipe.

In the water collecting basin device having such a structure,
Between the projecting flange plate integrally formed in the box body and the pipe (fume pipe) connected to the box body through a pipe joint, a floating support and pipe support member (a rectangular parallelepiped concrete block) Is intervening. Therefore, the weight of the concrete block directly acts on the projecting flange plate, and the measure main body arranged in the prepared hole is temporarily fixed in position. As a result, even if earth and sand are put into the fitting gap between the cell body and the prepared hole, the cell body will not be displaced.

Further, the weight of the concrete block having a high weight density directly acts on the protruding flange plate to press the measure main body downward. Further, the reaction force of the pressing force acting on the protruding flange plate acts on the pipe through the concrete block, and the pipe is firmly supported. Further, as a result of the weight of the pipe (a pipe that is a long heavy object) itself exerting a pressing force on the projecting flange plate via the concrete block, the lift of the box body is completely prevented.

Further, the box body is connected to a pipe through a pipe joint. The thin collar plate portion of the pipe joint is adhered to the inner surface of the wall of the box body, and the cylindrical portion protruding from the cell body is internally fitted to the end of the pipe. Therefore, there is no possibility that the box body will be distorted by the weight of the pipe.
Further, there is no risk of water leakage, and the cylindrical portion to be fitted inside acts as the center of the pipe end portion, and reinforces the dropout of the pipe connection.

[0014]

1 is a sectional view showing a concrete embodiment of a water collecting basin device according to the present invention, and FIG. 2 is a perspective view thereof.

The water collecting basin device is composed of a synthetic resin basin body 1, a pipe joint 2 which is fitted into a through hole 11 in a wall surface of the basin body 1, and is fitted into a pipe 5, and a bottom end of the basin body 1. And a projecting flange plate 3 projecting continuously from the portion
And a pipe support member 4 also for preventing rising, which is interposed between the pipe 5 and the pipe 5.

The box body 1 is made of a hard synthetic resin material such as FRP and is formed into a rectangular tube shape having an open top and a bottom. That is, the box body 1 is a rectangular parallelepiped having an open upper surface, and the lid plate (grating) 17 is attached to the upper opening surface portion 13. Lid plate 17
Is supported by a supporting step portion 12, and although not shown, one end thereof is pinned to a flange frame of the upper opening surface portion 13 and is pivotally supported so as to be openable and closable.

The protruding flange plates 3 are integrally and continuously provided at both ends of the bottom surface 14 of the box main body 1. The projecting flange plate 3 in the form of a flat plate is provided with the wall surface 15 of the box body 1 and the opposing wall surface 1
5a, each of which has substantially the same thickness as the bottom surface of the box main body 1 and the same width as the wall surface 15 (15a), is protruded by a predetermined length. In addition, the through holes 11 and 11 of the box body 1
Is provided at a substantially central portion of the depth of the wall surfaces 15 and 15a. Therefore, the protruding flange plate 3 and the cylindrical portion 2 of the pipe joint 2 described later.
1 and 1 are projected in parallel in the same direction.

The pipe joint 2 has a through hole 11 formed in the box body 1,
11 is fitted and deployed. The pipe joint 2 is a short pipe that is formed of a synthetic resin material such as vinyl chloride, and includes a collar plate 22 and a cylindrical portion 21 that continuously protrudes from the collar plate 22. Collar plate 22
Is set to be larger than the diameter of the through hole 11 and the plate thickness is set to be extremely thin. In the embodiment, it is set to about 3 mm. Thereby, in the state where the cylindrical portion 21 projects outward from the through hole 11 and the collar plate 22 is adhered (silicon resin adhesive) to the inner surface of the wall surface 15 (15a), water leakage is prevented and the thickness of the collar plate 22 is extremely thin. The sludge suction hose is set so that there is no support.

As shown in FIGS. 1 and 2, the pipe (fume pipe) 5 comprises a cylindrical pipe portion 51 and a rectangular outer cylindrical portion 52 surrounding the cylindrical pipe portion 51. The end of the pipe 5 is set so that the end of the cylindrical pipe portion 51 slightly projects. The inner diameter of the cylindrical pipe portion 51 is set so as to correspond to the outer diameter of the cylindrical portion 21 of the pipe joint 2, so that the cylindrical portion 21 is properly fitted into the cylindrical pipe portion 51.

As the above-mentioned pipe support member 4 also used for preventing floating, a heavy product having a high composition density is selected. Here, a member having a high composition density (a member having a high weight density) means that when placed on the upper surface of the protruding flange plate 3, in comparison with the weight applied to the area of the flange plate 3, it is more than the compacting earth or sand or the mortar to be poured. A member that becomes heavy. For example, a thick iron plate, copper plate, or the like can be considered. In the embodiment, a concrete block having high weight density is used. The concrete block 4 has a rectangular parallelepiped shape and its width and length are set to be substantially equal to the width of the protruding flange plate 3. The bottom surface 42 of the concrete block 4 is in contact with the top surface of the protruding flange plate 3, and the top surface 41 is in contact with the bottom surface 52a of the rectangular outer cylindrical portion 52 of the pipe (Hyumu pipe) 5. There is. In the embodiment, 2
It shows a state in which individual concrete blocks 4 are vertically stacked and arranged on the protruding flange plate 3 (FIG. 1).

When the water collecting basin device having such a structure is provided on the road surface 6, a prepared hole is opened in advance on the road surface 6 as shown in FIGS. Then, in this prepared hole
Insert. The cell body 1 is placed on the upper surface of the horizontal base 8. That is, the bottom surface 14 of the box main body 1 and the protruding flange plate 3 continuous with the bottom surface 14 are placed on the base 8.

After that, the cylindrical portion 21 of the pipe joint 2 is fitted into and connected to the end portion of the pipe (cylindrical pipe portion 51) 5. Therefore, there is no possibility of water leakage, and the cylindrical portion to be fitted inside acts as the center of the pipe end portion, and reinforces the dropout of the pipe connection. Further, the collar plate 22 of the pipe joint 2 is set to have an extremely thin thickness. Therefore, the collar plate 22 adhered to the inner surface of the wall surface 15 (15a) does not largely project inward of the box main body 1, and there is no support for taking in and out the sludge suction hose.

Then, the concrete block 4 is interposed between the protruding flange plate 3 and the bottom surface 52a of the pipe (square outer cylindrical portion 52) 5. The weight of the concrete block 4 directly acts on the protruding flange plate 3 and the protruding flange plate 3
Is pressed downward, and the position of the main body body 1 is temporarily fixed. Therefore, even when the earth and sand are put into the fitting gap between the prepared hole and the cell body 1, the cell body 1 is not likely to be displaced.

Further, in the concrete block 4, the bottom surface 42 contacts the top surface of the protruding flange plate 3, and the top surface 41 contacts the bottom surface 52a at the end of the pipe 5. As a result, the weight of the concrete block 4 having a high weight density directly acts on the protruding flange plate 3 to strongly press the measure main body 1 downward, and the reaction force of the pressing force acting on the protruding flange plate 3 is Acting on the pipe 5 via the block 4,
The end of the pipe 5 is firmly supported. Further, as a result of the weight of the pipe (a pipe that is a long heavy object) 5 itself exerting a pressing force on the projecting flange plate 3 via the concrete block 4, the lift of the box main body 1 is completely prevented.

Further, as shown in FIG. 3, since the protruding flange plates 3 and 3 are provided so as to project in a direction parallel to the road shoulder block 61 that divides the road surface 6 and the sidewalk surface 62, the road shoulder block 61 is opened when the pilot hole is opened. There is no need to dismantle, and a small pilot hole can be opened. Furthermore, the box body 1 is in the shape of a rectangular tube (a rectangular parallelepiped).
Therefore, it is easy to open the through hole (true circular hole) 11 for pipe connection, which is opened in the vertical wall surface 15 of the square body 1.

[0026]

As described above, according to the present invention, the floating flange plate projecting from the lower end of the wall of the synthetic resin box main body and the pipe connected to the box main body through the pipe joint are lifted up. Since the prevention / support pipe support member is interposed, the lift prevention / support pipe support member presses the protruding flange plate downward. Therefore, the measure main body is fixedly arranged in the prepared hole in a temporarily fixed shape, and the measure main body is not likely to be displaced even when earth and sand are put into the fitting gap between the prepared hole and the measure main body. In addition, the lifting prevention and piping support member presses the protruding flange plate downward, and this reaction force supports the lifting prevention and piping support member at the pipe end, and the weight of the piping also supports the lifting prevention and piping support. The protruding flange plate can be pressed through the member to completely prevent the lift of the box body. In addition, long and heavy pipes are supported by a lifting support pipe support member that does not directly affect the weight of the box body.
Disadvantages such as distortion of the box body are eliminated. In addition, the cylindrical portion of the pipe joint functions as a center of the pipe end by being fitted into the pipe end, thereby preventing leakage and reinforcing the bearing of the pipe end.
Moreover, since the collar plate of the pipe joint is set to have an extremely thin thickness, there is no problem in taking in and out the sludge suction hose. Furthermore, since the protruding flange plate is provided only on the two opposing wall surfaces of the rectangular box body,
The preparation of the prepared hole is easy because the preparation of the prepared hole is small and there is no need to break the shoulder block on the road surface. Further, since the square body has a rectangular tube shape, it does not require a special tool for opening a perfect circular through hole for connecting a pipe, and thus has the excellent effects of achieving the object of the invention.
