(57) [Summary] [Purpose] The purpose is to alleviate the tilting of the rising pipe fitted into the upper opening of the drainage basin and to eliminate the inclination of the drainage basin. [Structure] A ring body (2) externally inserted on the outer peripheral surface of a rising pipe (104) fitted into an upper end opening (103) of a box body (100) and a horizontal rib body (3) fixed to a central portion of the outer peripheral surface of the ring body (2) to prevent inclination. Configure the ingredient 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tilt preventive tool for preventing a buried drainage container from tilting.

[0002]

[Prior Art]

 For example, as shown in FIG. 4, a drainage basin installed in a general house is constructed by connecting drainage pipes 102 and 102 to drainage pipe connection ports 101 and 101 of a basin body 100 made of synthetic resin. A rising pipe 104 is fitted into the upper end opening 103 and is buried in the ground.

[0003]

[Problems to be solved by the device]

 However, in the case where the rising pipe 104 is fitted into the sill body 100 and is backfilled into the ground, if the backfilling is insufficient or the ground is soft, the upper end opening 103 of the sill body 100 is insufficient. Since the length of the riser pipe 104 is 2 to 4 times as long as the inner diameter of the riser pipe, as shown in FIG. 4, when the riser pipe 104 is obliquely pressed, there is no support so that the riser pipe 104 easily tilts as it is. The slope body 100 in which the rising pipe 104 is fitted is also inclined, and the drain pipe 102 is disengaged from the drain pipe connection port 101 to hinder the flow of drainage, or backflow or splashing of drainage occurs. There was a problem that the inside of the basin body 100 was easily soiled.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a device for preventing the inclination of a drainage basin of the present invention comprises a ring body slidably inserted into a rising pipe fitted into an upper end opening of the basin body, and a horizontal body extending around the periphery of the ring body. It is characterized by comprising a rib body.

[0004]

[Action]

 According to the device for preventing inclination of the drainage basin configured as described above, when the ring body with the horizontal rib body is externally fitted to the rising pipe and the basin body is buried in the ground, the horizontal rib body makes contact area with earth and sand in the ground. Increase, the horizontal ribs are fully embedded in the sand and the rising pipe is buried.When this rising pipe is pushed diagonally, this force is received by the horizontal ribs and the vertical pressing force is increased. The ring body now moves up and down the rising pipe, and the rising pipe is no longer tilted directly, and the tilting of the sill body to which this rising pipe is fitted can be prevented.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a tilt preventive tool 1 for a drainage basin according to an embodiment of the present invention, and FIG. 2 is a side view showing a partially cutaway sectional view of the tilt preventive tool 1 in use. . The tilt stopper 1 is composed of a ring body 2 and a horizontal rib body 3 attached around the ring body 2.

The ring body 2 is, for example, a ring made of a synthetic resin such as polyvinyl chloride resin or a light metal such as aluminum, and the inner diameter of the ring body 2 is fitted into the upper end opening 103 of the basin body 100 of the drainage basin 104. Is slightly larger than the outer diameter of the rising pipe 104 and is slidable in the vertical direction along the outer peripheral surface of the rising pipe 104.

The horizontal rib body 3 attached to the central portion of the outer peripheral surface of the ring body 2 is a donut-shaped disc made of a synthetic resin such as polyvinyl chloride resin similar to the ring body 2 or a light metal such as aluminum. There, it is firmly fixed to the outer peripheral surface of the ring body 2 by an adhesive or welding.

As shown in FIG. 2, the tilt preventive tool 1 is inserted into a rising pipe 104 which is fitted into an upper end opening 103 of a container body 100, positioned at an appropriate position, and embedded in earth and sand to be used. Used. If the tilt preventive tool 1 is inserted in the rising pipe 104 and the earth and sand are backfilled, the contact area between the horizontal rib body 3 and the earth and sand is increased, and the earth and sand are sufficiently meshed with each other. Even if the ground surface is stepped on in a sufficient state and a diagonal force is exerted, the horizontal rib body 3 having a large area receives the force, and the diagonally applied force is converted into a vertical force, so that the ring body 2 is moved. The riser pipe 104 slides vertically to absorb the force. Therefore, there is no fear that the rising pipe 104 will tilt, the basin body 100 itself fitted at the lower end will not be tilted, and the drain pipe 102 will come off the drain pipe connection port 101 and hinder the flow of drainage. The inside of the basin body 100 is not polluted due to backflow or splash of drainage.

Further, even if the frozen ground in the cold district causes a bulge on the ground surface, the horizontal rib body 3 receives a rising force, and only the tilt prevention tool 1 rises on the outer peripheral surface of the rising pipe 104. The rise of the rising pipe 104 can be prevented, and the sill body 100 will not be lifted.

The tilt preventive tool 1 is not limited to the configuration of the above embodiment, and the ring body 2 that slides on the outer peripheral surface of the rising pipe 104 has a rectangular horizontal outer shape as shown in FIG. It may be a tilt preventive tool 1a in which a rib body 31 or a horizontal rib body having a polygonal shape or a mesh shape is fixed and integrated, and the ring body 2 and the horizontal rib body 3 are vertically divided as a unit. The divided surfaces may be joined with a fastener such as a bolt and a nut, an adhesive, or the like, and integrally mounted on the rising pipe 104.

Further, when a plurality of tilt preventive tools 1 and 1a are attached to the rising pipe 104 at a predetermined interval, the contact area with the earth and sand is further increased, so that the inclination of the rising pipe 104 is eased especially in soft ground. It is possible to effectively prevent the tilt of the drainage basin.

[0013]

[Effect of the device]

 As is clear from the above description, in the device for preventing inclination of the drainage basin of the present invention, the horizontal rib body increases the contact area with the earth and sand, and it becomes difficult for the horizontal rib body to receive force and directly transmit it to the rising pipe. The tilt preventive tool slides in the vertical direction of the rising pipe to absorb the force, and there is no concern that the drainage pipe fitted with the rising pipe will tilt.
