TECHNICAL FIELD The present invention relates to a drainage mass.

[0002]

2. Description of the Related Art Conventionally, drainage flowing out from a kitchen or a kitchen is once made to flow into a drainage mass and then to the sewer main from this drainage mass.

The structure of this drainage mass is as follows.
As described in Japanese Patent Publication No. 71, No. 71, which is composed of a lid, an auxiliary mass, and a mass main body, in which a mass main body into which drainage flows in and out is buried in the ground, and a mass main body in the ground and a lid on the ground Are connected with an auxiliary mass.

Usually, the connection between the lid and the auxiliary mass is
As described in the above publication, a cylindrical protrusion provided on the lower surface of the lid is inserted into a U-shaped receiving portion provided at the upper end of the auxiliary mass.

[0005]

However, if the cylindrical protruding portion provided on the lower surface of the lid is simply inserted into the receiving portion of the auxiliary mass having a U-shaped cross section, rainwater leaks from here and the inside of the drainage mass is leaked. There is the problem of rainwater entering the area.

In order to eliminate such a problem, a seal member is usually provided on the bottom surface of the U-shaped cross section which is the receiving portion to make the space between the cylindrical projecting portion and the receiving portion watertight. However, the lid is often removed to inspect and clean the inside, but when the lid is often removed, earth and sand enter the receiving part, and this earth and sand accumulates on the sealing material provided on the bottom surface, and the lid is removed. When closed, sand and sand are sandwiched between the lid and the sealing material, the watertightness between the tubular projecting portion and the sealing material deteriorates, and rainwater leaks from between the tubular projecting portion and the sealing material.

Therefore, an object of the present invention is not to impair the watertightness between the receiving portion having a U-shaped cross section provided at the upper end of the auxiliary mass and the cylindrical protruding portion provided at the lower surface of the lid, and is simple. It is to provide a drainage mass that can be installed in.

[0008]

The present invention has been made to solve the above problems and achieve the above object. In a drainage mass including a lid, an auxiliary mass, and a mass body, the auxiliary mass has an upper end. It is a tubular body provided with a U-shaped cross-section receiving part, and a locking projection is provided on substantially the entire circumference of the inner or outer peripheral surface of the U-shaped cross-section receiving part, and the lid is A cylindrical projection is provided on the lower surface, and a locking projection is provided on substantially the entire circumference of the outer peripheral surface or the inner peripheral surface of the tip of the projection, and the lid cylinder is provided in the receiving portion of the auxiliary mass. The protrusions are inserted, and the locking projections of the auxiliary mass and the locking projections of the lid are locked via the sealing material.

In the present invention, the outer peripheral surface or the inner peripheral surface in the receiving portion having the U-shaped cross section is the surface facing the outside of the U-shaped inner surface of the cross section, and the surface facing the center. It is called the inner surface.

In the present invention, the cylindrical protrusion provided on the lower surface of the lid is inserted into the receiving portion of the auxiliary mass having a U-shaped cross section, and the engaging protrusion of the auxiliary mass and the engaging protrusion of the lid are provided. There are various ways to do this, but the simplest way is to insert the protruding part of the lid into the receiving part of U-shaped cross section. At this time, the inner diameter of the protruding wall on the outer side of the U-shaped section is made larger than the outer diameter of the cylindrical protruding portion of the lid so that the lid is displaced in the horizontal direction, and the locking protrusion or the receiving portion of the protruding portion of the lid is A structure in which a sealing material is adhered to the entire circumference of the locking convex locking portion is inserted, the protruding portion of the lid is inserted into the receiving portion having a U-shaped cross section of the auxiliary mass, and the lid is displaced to engage the protruding portion. There is a method of locking the stop projection to the locking projection of the receiving portion.

At this time, a part of the lid and the receiving portion may be cut out so that the lid can be easily inserted. The distance to be displaced may be appropriate, but is preferably 2 to 5 mm.

As another method, half the sealing material is adhered to the circumferences of both the locking projections of the tubular projection of the lid and the locking projections of the receiving portion, and the sealing materials are overlapped. Insert the tubular protrusion of the lid into the receiving portion of the auxiliary mass and
There is a method in which the seal material is provided on the entire circumference by rotating it by °.

The sealing material used in the present invention is preferably a soft synthetic resin foam such as polyethylene foam, a rubber foam such as natural rubber, or an elastic body such as natural rubber or synthetic rubber or soft polyvinyl chloride. is there.

The shape of the sealing material is an annular shape which is inserted in the receiving portion of the auxiliary mass having a U-shaped cross section, and the cross section is rectangular, semicircular, triangular, kamaboko-shaped, L-shaped, or protruding on the rectangle. Those having an appropriate shape, such as the one having a groove, can be used.

[0015]

According to the present invention, the engaging protrusion is provided on substantially the entire circumference of the inner peripheral surface or the outer peripheral surface of the receiving portion having the U-shaped cross section of the auxiliary mass, and the outer peripheral surface of the tip portion of the cylindrical protruding portion of the lid is provided. Alternatively, since the locking projection is provided on almost the entire circumference of the inner peripheral surface and the locking projection of the auxiliary mass is locked to the locking projection of the lid through the seal material, The sealing material is provided at a position higher than the bottom surface of the U-shaped cross section.

Therefore, even when the lid is frequently removed, even if the earth and sand fall into the receiving portion, they are only deposited on the bottom portion having a U-shaped cross section and not on the sealing material. Therefore, the watertightness of the sealing material does not become defective due to this earth and sand.

If the structure is such that the cover can be displaced, the cover can be easily opened and closed.
