The present invention relates to prefabricated manholes for sewage and sewage, and more particularly, to prefabricated manholes for sewage and sewage, and more particularly, to minimize the phenomenon of odor flow back to the drainage of sewage and sewage generated and discharged from buildings. The present invention relates to a prefabricated manhole for sewage and sewage that can be smoothly drained, can be quickly and easily installed, and can be replaced as needed to replace important areas where corrosion and friction deformations frequently occur during use. .

Generally, sewage and sewage discharged from buildings are discharged into septic tanks to be cleaned.

Here, sewage is discharged from the toilet and sewage is generated and discharged from the kitchen and the toilet, and these are discharged to the septic tank through each drain pipe to be treated.

The sewage and sewage discharged from the inside of the building is discharged to the septic tank through the manhole installed outside the building.

However, manholes in the related art have problems such as long manhole construction period and waste of labor cost because manholes are made by reinforcing concrete using formwork in the field and making manholes.

In addition, in the construction of the manhole, it is necessary to use a fire extinguishing trap, which frequently causes clogging, and thus, drainage is not performed properly.

Therefore, in recent years, efforts to solve such problems have been sought from various angles. An example (published No. 10-2004-0000861) is described as follows.

This, the partition 11 is formed in the middle of the resin body 10 to have a first discharge space portion 12 and the second discharge space portion 13, the first discharge space portion 12 is a drain port 14 A bottom surface 15 inclined downward in a direction is formed, and a sewage pipe 16 for discharge of sewage (w) is installed to be piped on one side, and the sewage (w ') discharge is discharged to the second discharge space portion 13. The sewer pipe 17 is installed to be piped, but the sewer pipe 17 is connected to the elbow pipe 18 is installed so that the drain hole (18a) is directed downward, the second discharge through the elbow pipe (18) Sewage (w ') discharged to the space 13 is formed in the partition 11 and drained to the first discharge space 13 through the drain hole 19 is covered with a stainless steel mesh 21, but elbow pipe (18) And the upper portion of the first and second discharge spaces 12 and 13 are opened and closed by resin covers 20 and 20 'so as to be formed at a position higher than the drain hole 18a of Whereas that facilitate drainage and to ease the manhole construction yet can be made to prevent backflow of sewage smells can promote resource conservation sigongbi according to the conservation and utilization of waste products, including labor costs, it has the following problems.

If you list them in order, they are as follows.

First, in order to form the first and second discharge space portion separately, the volume of the main body was made larger than necessary, and the outer shape of the main body was formed stepwise to form such a space portion, and in the first and second discharge space portions thus formed In order to separate the sewage and sewage separately, there was a problem in that the construction of the pipe connection structure had to be formed separately.

Second, the structure that prevented and formed odor backflow by sewage provided a factor that caused odor backflow.

That is, since the drain hole is higher than the drain hole of the elbow pipe that introduces the sewage, the effect of preventing odor backflow into the sewer pipe can be expected initially, but a certain amount of sewage remains in the second discharge space. This is because, after a certain period of time, the odor caused by this phenomenon flows back into the room through the sewer pipe.

Third, there is a problem in that the drainage is not made smoothly because the discharge treatment is frequently generated because the filtration treatment for the incoming sewage and sewage is weak.

In other words, only one stainless steel mesh can be used for filtration of sewage and sewage flowing into the entire composition, and these components are also installed in a position where an effective filtration stroke cannot be expected.

More specifically, since the sewage flowing into the second discharge space portion is transferred to the stainless steel mesh after an overflow flow in this space, a large amount of foreign matter is already present in the second discharge space portion during the overflow process. This is because it is delivered after precipitation.

The present invention has been made in view of the above-mentioned problems in the prior art, the object of the present invention relates to prefabricated manholes for sewage and sewage, more specifically, the smell of sewage and sewage drainage generated and discharged from the building Sewage and sewage can be improved as necessary to minimize reversal, achieve smooth drainage, install quickly and easily, and replace critical areas where corrosion and friction deformations frequently occur during use. To provide a prefabricated manhole.

Specific means of the present invention for achieving the above object,

Therefore, the definition should be made based on the contents throughout the specification.

As shown, it has an inverted conical shape, the upper part of which is opened, and the lower and rear mouths to which sewage pipes 11 and drain pipes 12 and septic tank connection drains 13 for inflow of sewage and sewage are connected. Outlets 14a, 14b, and 15 are formed, and an insertion fixing protrusion 16 is formed before and after the inner space portion, and a main body (1) having a locking jaw 17 formed on one inner circumference thereof. 10) is formed.

In the main body 10, the internal space is formed to be divided into first and second discharge spaces 21 and 22, but a through hole 23 is formed at one side and one side. The divided panel 20 in which the discharge hole 24 is formed is inserted into the bent portion extending downward, and the first and second inflow spaces 21 and 22 are formed by the divided panel 20. The upper part of the main body 10 which is divided into the upper cover 30a, 30b which is connected to the sieve net 31 hinged is configured to open and close it.

On the other hand, the discharge hole 24 of the split panel 20 is connected to the blocking plate 25 to achieve the folding operation by the falling hydraulic pressure and load of the incoming sewage and sewage.

Referring to such components will be described the operation and effect of the present invention.

This is because the main body 10 is placed in the ground which has been destroyed to achieve the installation, and the sewage pipe 11, the drain pipe 12, and the septic tank outside the inlet, outlet 14a, 14b, and 15 of the main body 10. The connection drain port 13 may be connected.

When the connection is completed, the space is formed inside the main body 10 from the opened upper part of the main body 10 after the soil is backfilled to the outside of the main body 10 located in the ground which is thus excavated. The split panel 20 is inserted into and fixed to the insertion fixing protrusion 16 formed before and after, and the split panel 20 is divided into first and second inflow spaces 21 and 22 by the split panel 20. Assembled installation is completed by inserting the cover (30a, 30b) which is formed integrally with the sieve network 31 from the upper portion of the main body 10 to the lower portion.

The present invention, which is assembled and installed in this way, has a very suitable shape for installing the main body 10 embedded in the ground during use, as well as an externally connected sewage pipe 11 and drain pipe 12 and a septic tank connecting drain hole ( 13, the entrance and exit 14a, 14b, and 15 are formed in consideration of the connection copper wire with the maximum, so that the landfill installation and the connection installation can be made relatively quickly and easily.

In addition, the sewage and sewage flowing in and out of the sewage pipe 11 and the drain pipe 12 connected to the inlets 14a and 14b of the main body 10 may be separately partitioned by the split panel 20 upon inflow. The second inflow space 21, 22 is introduced into the first, first, the sewage flowing into the first inflow space 21 to the outlet 15 located in the lower portion along the inner peripheral surface formed to be concave downward After being delivered dropping, it is smoothly drained through the septic tank connecting drain 13 connected to the outside of the outlet 15.

In more detail, the sewage that is introduced into the first inflow space 21 and is dropped and delivered to the outlet 15 and then drained is disposed in the discharge hole 24 of the split panel 20 in the falling transfer process. In this case, the sewage delivered to the outlet 15 via the discharge hole 24 opens the blocking plate 25 installed in the discharge hole 24 by folding hydraulic pressure and a load, and then connects the septic tank connecting drain 13 Will be delivered.

Then, the blocking plate 25 which is folded by the drop hydraulic pressure of the sewage and the load to open the discharge hole 24 to plan the drainage stroke is again discharged to the discharge hole 24 by its elastic restoring force after the drainage treatment. Will be closed.

On the other hand, the sewage flowing into the second inflow space 22 is introduced into the second inflow space 22 and then passed through a predetermined passage process to the outlet 15 to be delivered to the drainage process, the split panel ( Except for passing through the through-holes 23 of 20, the discharge hole 24 of the split panel 20 and the blocking plate 25 installed therein as in the above-described wastewater in the process of drop transfer to the outlet (15). It will be drained smoothly via.

Therefore, it is possible to achieve a smooth discharge stroke of the sewage and sewage drained through the main body 10 corresponding to the manhole, and to fundamentally prevent the remaining of the sewage and sewage in the main body 10. And, it is possible to prevent the odor that flows back into the building by the discharge delay and remaining sewage and sewage in the main body 10 corresponding to the manhole in advance, the outlet 15 and the septic tank connection drain 13 It is generated by the sewage and sewage remaining in the to be able to minimize the backflow odor delivered to the body (10).

The sewage and sewage introduced into the main body 10 cover the first and second inflow spaces 21 and 22 which are respectively partitioned so as to be closed so as to be closed in an initial process flowing into the main body 10. ), (30b) is delivered to the outlet 15 after the maneuvering process by the filtration network 31 hinged to the lower portion of the outlet 15 is blocked by the foreign matter contained in the sewage and sewage discharged to the outlet 15 is discharged Problems that occur can be prevented in advance.

In addition, the cover 30a, 30b is opened to be inserted into the partitioned first and second inflow spaces 21, 22 of the main body 10 in the process of checking whether there is an abnormality in the main body 10. When a large amount of foreign matter is deposited in the filtering mesh 31 is located, the cover 30a, 30b to the outside to remove the foreign matter, so that the cleaning in the main body 10 corresponding to the manhole quickly and easily It becomes possible.

In addition, since the direct contact with the contaminated sewage and sewage is directly connected to the main body 10, the split panel 20 is installed in a structure that is easily connected to the main body 10. Economical maintenance is possible and semi-permanent use is possible.
