Abstract

PURPOSE:To prevent water leakage from a swing socket used for joints of pipes buried in the underground. CONSTITUTION:The outer peripheral face of a swing socket 1 is protrusively formed so as to shape a curved face outward. The inner peripheral face at one end of a reinforcing pipe body is formed to make a straight pipe so as to contact the outer peripheral face of a sewer pipe 9. The inner peripheral face at the other end of the reinforcing pipe body 22 is formed to shape a curved face so as to extend along the outer peripheral face of the swing socket 1. The reinforcing pipe body 22 is formed to shape a half-divided pipe in the axial direction. An upper reinforcing pipe body 26 and a lower reinforcing pipe body 27 are formed. In this way, the sewer pipe 9 is prevented from deforming flat due to the earth pressure from the upper side and also water leakage between the swing socket 1 and the sewer pipe 9 can be prevented. Even when a sewer pipe 9 is connected to a catch-basin 2 at an acute angle, the reinforcing pipe body 22 can be closely fitted to the swing socket 1.

2. Description of the Related Art Conventionally, large manholes made of concrete have been used for the inspection port of sewer pipes, but since these large manholes are difficult to install on narrow roads or in bends, vinyl chloride resin has been used in recent years. Manufactured small manholes have been used.

Although it is obligatory to install a manhole at a bending point or when a certain distance (for example, 50 m) is exceeded, since there are few cases where roads continue straightly, there is a slight angle between the inlet and outlet of the manhole. Are often different. In such a case, if the inlet of the manhole is a free receiving port, the angle can be easily adjusted, which is very convenient.

As shown in FIG. 8, the universal receiving port 1 is formed integrally with the container main body 2, and is formed with an outer tube 3 made of synthetic resin such as vinyl chloride resin which is bulged outward in a curved shape. A rotary receiving portion 5 made of synthetic resin having a large rigidity, which is rotatably fitted to the inner peripheral surface of the outer tube 3 through an elastic ring 4. Annular recesses 6 and 7 are respectively provided on the outer peripheral surface and the inner peripheral surface of the rotation receiving portion 5, the elastic ring 4 is mounted in the annular recess 6, and the elastic packing 8 is fitted in the annular recess 7. Has been done.

Then, according to the bending condition of the installation site, the connection pipe 9 is connected to the universal receptacle 1 at a predetermined angle with respect to the basin body 2 and then backfilled. At this time, the connection angle of the connection pipe 9 can be easily changed by rotating the rotation receiving portion 5.

Next, the rising pipe 10 is erected from the upper part of the main body 2 toward the ground surface. It should be noted that a protective casing 11 is provided near the surface of the earth located above the rising pipe 10, and a protective casing seat 12 for supporting the protective casing 11 is arranged below the protective casing 11 so that the rising pipe 10 and the basin body No load from vehicles on the road is directly applied to No.2.

However, when it is buried deep underground, earth pressure is applied to the connecting pipe 9 and the universal receiving port 1 from above. Here, as described above, the universal socket 1
Has a double structure including the outer tube 3 and the rotation receiving portion 5 having high rigidity, and therefore has substantially higher rigidity than the connecting tube 9. For this reason, the connecting pipe 9 is easily deformed into a flat shape by earth pressure so that the dimension in the vertical direction is shortened, whereas the universal receiving port 1 having a large rigidity is not deformed following the connecting pipe 9. There is a problem that a gap is created between the pipe 9 and the elastic packing 8 fitted in the rotary receiving part 5, and water may leak from the gap or unknown water may enter the inside. .

The present invention has been made in view of the above problems, and an object of the present invention is to provide a water leakage prevention device for preventing water leakage from a universal receptacle used in a joint portion of a pipe body buried underground. .

[0009]

The water leakage prevention apparatus of the present invention has a universal receptacle having an outer peripheral surface bulging outward in a curved shape and an inner peripheral surface at one end serving as the universal receptacle. It is formed in a straight tube shape so as to be in contact with the outer peripheral surface of the connecting pipe to be connected, and the inner peripheral surface of the other end is formed into a curved surface so as to follow the outer peripheral surface of the universal receptacle, and is halved in the axial direction. And a reinforcing tube body formed in the.

[0010]

In the water leakage prevention device of the present invention, when buried underground, the connecting pipe located in the vicinity of the universal receiving port is fitted and reinforced at one end portion of the reinforcing pipe body, so that the connecting pipe is installed from above. It is not deformed into a flat shape by earth pressure, no gap is formed between the connecting pipe and the universal receiving port, and water leakage is prevented.

Also, when the connecting pipe is freely joined to the main body at an angle, the inner peripheral surface of the other end of the reinforcing pipe is curved along the outer peripheral surface of the universal receptacle. Since it is formed, the other end of the reinforcing tube can be fitted snugly into the universal receptacle.

Further, since the reinforcing pipe is formed in half in the axial direction, the workability of attaching the reinforcing pipe is improved.
