[Problems to be solved by the device]

 However, in such a conventional drainage system, when repairing a road, etc., only the pedestal ring is raised without raising the rising pipe, so that the upper end of the rising pipe is However, it was relatively lower than the protective cylinder and manhole cover above it, and it was sometimes difficult to remove the inner cover from the upper end of the rising pipe. In addition, since the rising pipe is not raised, stones or the like may be clogged between the upper end of the rising pipe and the pedestal ring, or the upper end of the rising pipe may be hidden by being buried in earth and sand.

The present invention has been made by paying attention to such a problem in the conventional drainage basin, and its purpose is to solve the above problem and to mount a pedestal ring when repairing a road. It also aims to provide a drainage basin that can easily raise not only the protective cylinder above it, the manhole cover, but also the upper end of the rising pipe.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the drainage basin according to the present invention is provided with a rising pipe above the body of the drainage muffler, a pedestal ring is provided on the side of the upper end of the rising pipe, and a protection cylinder is provided on the pedestal ring. The lower end of the drain is placed on the upper end of the protective cylinder so that the manhole cover can be opened and closed.In the upper part of the drainage body, the upper end has the receiving port and the lower end has the spout. The lower end of the pipe joint is inserted and connected, the lower end of the rising pipe is inserted and connected to the upper end receiving port of the pipe joint, and the upper end of the rising pipe is locked to the pedestal ring. Is.

[0006]

[Action]

 In the drainage basin according to the present invention, a rising pipe is provided above the main body of the drainage basin, a pedestal ring is provided at the side of the upper end of the rising pipe, and the lower end of the protective cylinder is placed on the pedestal ring. A manhole cover is provided on the upper end of the protective cylinder so that it can be opened and closed.The drainage is drained.The upper end of the main body has a receiving end at the upper end and an outlet at the lower end. Since the lower end of the rising pipe is inserted and connected to the upper end receiving port of the pipe joint, the upper end of the rising pipe can be adjusted by adjusting the insertion depth of the lower end of the rising pipe into the upper end receiving port of the pipe joint. The height of the section can be adjusted, and the upper end of the rising pipe can be raised.

Furthermore, since the upper end of the rising pipe is locked to the pedestal ring, the upper end of the rising pipe is raised and then the upper end of the rising pipe is locked to the pedestal ring. The position of the upper end of the pipe can be fixed.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a cutaway front view of a right half portion showing an embodiment of the present invention.

In FIG. 1, reference numeral 1 is a body for drainage made of hard vinyl chloride resin, a receiving port 11 is provided above it, and connection ports 12 and 13 having a diameter of about 200 mm are integrally provided on the left and right sides, and a drain pipe (not shown) is provided. Ready to connect.

Reference numeral 2 is a pipe joint made of a hard vinyl chloride resin, the lower end portion of the pipe joint 2 is an inlet 21, the upper end is a receiving opening 22 having a diameter of about 300 mm, and the outlet 21 is drained. It is inserted in the receptacle 11 of the. Reference numeral 23 is a rubber ring provided in a recess of the upper end receiving port 22 of the pipe joint 2. 3 is a rigid vinyl chloride resin rising pipe, the lower end of which is inserted and connected to the upper end receiving port 22 of the pipe joint 2, and the rising pipe 3 has an insertion depth of 100 to 500 in the upper end receiving port 22 of the pipe joint 2. It can be adjusted in millimeters. As shown in the partially cutaway perspective view of FIG. 2, a flange-shaped locking portion 31 is provided at the upper end of the rising pipe 3. As shown in the partially cutaway perspective view of FIG. 3, the locking portion provided at the upper end of the rising pipe is formed by bending the rising pipe 3a at the upper end opening peripheral edge at three locations outwardly. It may be the pieces 31a, 31a, 31a.

Reference numeral 4 denotes an inner lid made of hard vinyl chloride resin, which is provided on the upper end of the rising pipe 2. Reference numeral 5 denotes a polyethylene pedestal ring provided laterally around the upper end of the rising pipe 2, and has a concave step portion 51 provided on the inner circumference thereof. The formed brim-shaped locking portion 31 is locked. Reference numeral 6 is a cast iron protective cylinder, and the protective cylinder 6 is mounted on the upper end flange-shaped locking portion 31 of the rising pipe 3 which is locked and mounted on the recessed step portion 51 of the pedestal ring 5. Reference numeral 7 denotes a cast iron manhole cover which is pivotally attached to the protective cylinder 6 so as to be openable and closable.

[Effect of device]

 In the drainage basin according to the present invention as set forth in claim 1, the height of the upper end portion of the rising pipe can be adjusted by adjusting the insertion depth of the lower end portion of the rising pipe into the upper end receptacle of the pipe joint. Since the upper end of the pipe can be raised, unlike conventional products, when repairing a road, etc., the riser pipe was not raised and only the pedestal ring was raised. The upper end is relatively lower than the pedestal ring, the protective cylinder above it, and the manhole cover, and there is no drawback that it is difficult to remove the inner cover from the upper end of the rising pipe.

As in the illustrated embodiment, an engaging portion protruding outward is provided at the upper end portion of the rising pipe, and the engaging portion of the rising pipe is provided in a concave step portion provided in the pedestal ring. By placing and locking, the center axis of the riser pipe and the center axis of the pedestal ring can be aligned, and the lower end of the protective tube is placed on top of that, so the upper end of the riser pipe is pedestal. Can be securely locked and fixed to the ring.
