Description

Sewage conduit with circular overlapping cross-sectional structure {SEWER PIPE WITH CIRCULAR OVERLAPPING CROSS SECTIONAL STRUCTRE}

The present invention relates to sewage conduits, and more particularly, to sewage conduits having a circular overlapping cross-sectional structure capable of maintaining a desired flow rate even when the flow rate is high and the flow rate is low.

In general, people need clean water, and at the same time, they contaminate water through various activities, resulting in the production of sewage and wastewater. Therefore, the space where people live is connected with water supply to supply clean water and sewage to discharge sewage and wastewater. Here, clean water is delivered from the water purification plant to the living space through a constant conduit, and sewage and wastewater are transferred from the living space to the wastewater treatment facility through sewage conduits.

In particular, sewage conduits are generally designed to treat both contaminated water entering from around sewage conduits as well as waste water that is thrown away from the living space. Therefore, the sewage pipe is preferably designed to be able to move all without clogging by the flow rate flowing in the pipe, even if the soil, dirt, garbage, and the like moving with the rain water.

Therefore, sewage conduits prescribe minimum flow rates for the maximum amount of sewage per hour to prevent sediment and sedimentation at the bottom of the sewer. However, if the flow rate is lower than the standard, it is natural to deposit foreign matters in sewage pipes, and it is virtually impossible to prevent foreign matters from being deposited under irregular rainfall conditions.

In the case of sediment deposits in sewage pipes, the sediment can be impeded by the flow of sewage, leading to serious problems such as foul odor from sediments and even serious problems such as corrosion and breakage of pipes from hydrogen sulfide gas from sediments.

1 is a view illustrating a sewage conduit system having a circular overlapping cross-sectional structure according to an embodiment of the present invention.

Referring to FIG. 1, a sewage conduit system having a circular overlapping cross-sectional structure includes a sewage conduit 100 and a detector 400.

Sewage conduit 100 is a configuration for delivering the waste water flowing from the living space or surroundings to the sewage treatment area, the lower part of the sewage conduit 100 is supported and fixed by the conduit support 200. Sewer conduit 100 having a circular overlapping cross-sectional structure according to an embodiment of the present invention has a cross-sectional shape of the pentagon, it is possible to arrange so that the shape is upside down when installed.

For convenience of description, the portion corresponding to the belly portion of the otuigi shape that is the cross-section of the sewage pipe 100 will be referred to as "high flow conduit" and will be given the reference numeral of "110", to the head portion of the otuigi shape The corresponding part is called "low flow conduit" and will be given the reference numeral "120". That is, the sewage conduit 100 according to the embodiment of the present invention is one module that can be divided into a high flow rate conduit 110 and a low flow rate conduit 120 and the high flow rate conduit 110 is installed at an upper side. And a low flow conduit 120 is disposed on the lower side.

A description of the cross section of the sewage pipe 100 will be described in more detail with reference to FIG. 2. The high flow rate conduit 110, which is a part of the sewage conduit 100, includes an open section GG and has a circular cross section of a first diameter, and the low flow conduit 120 of the remaining part has an open section GG. It shares and has a circular cross section of a second diameter smaller than the first diameter in the outward direction of the high flow conduit 110. Subsequently, at both ends of the open section GG of the high flow rate conduit 110 and the low flow rate conduit 120, a contact point at which the high flow rate conduit 110 and the low flow rate conduit 120 are in contact with each other is formed. The position of the contact point is defined according to the size of the first diameter of the high flow rate conduit 110 and the second diameter of the low flow rate conduit 120.

Subsequently, the first flow conduit 310 is connected to the low flow conduit 120, and the second conduit 320 is connected to the high flow conduit 110. Here, the first connection pipe 310 is a configuration for transmitting the state of the water flowing in the low flow conduit 120 to the detector 400, the second connection pipe 320 to the high flow conduit 110 It is a configuration for transmitting the state of flowing water to the detector 400.

Next, the detector 400 receives the state of the flow of the low flow conduit 120 delivered through the first connection pipe 310 and detects the state of the flowing water, and the high flow rate delivered through the second connection pipe 320. Receiving the state of running water of the conduit 110 detects it. The arrangement and shape of the detector 400 may vary, and in this example, the detector 400 is installed on the ground. In the case of the detector 400, since it is possible to detect the state of running water of the sewage conduit 100 without directly observing the sewage conduit 100, a worker can analyze the inside of the sewage conduit 100 quickly. This makes it possible to quickly undertake appropriate maintenance work.

Here, the detector 400 may directly acquire the flowing water flowing in the high flow rate conduit 110 and the low flow rate conduit 120 to determine the state of the flow water, and determine the state of the flow water through the hydraulic pressure according to the flow rate. It is also possible. The state of the flowing water detected through the detector 400 may be whether the flowing water is detected or the components of the flowing water.

On the other hand, the flowing water flowing into the sewage pipe 100 may be divided into a case where the flow rate is small and the flow rate is large according to the flow rate. Thus, the detector 400 may detect the state of the flowing water through the first connector 310 when the flow rate is low, and the flow of the water through the first connector 310 or the second connector 320 when the flow rate is high. It is possible to grasp the state of the. In particular, when the flow rate is small, the detector 400 acquires air in the sewage pipe 100 provided through the second connector 320 because the flow of water does not rise to the position where the second connector 320 is connected. It is possible to do this and to analyze it.

In this way, the flowing water state and the air state in the sewage conduit 100 obtained from the detector 400 may be utilized as data for problem identification and maintenance of the sewage conduit 100. For example, it is possible to determine whether the water in the sewage conduit 100 is clogged by foreign matter, it is possible to determine whether the hydrogen sulfide gas generated in the sewage conduit 100.

Detector 400 according to an embodiment of the present invention is capable of detecting a clogging phenomenon or hydrogen sulfide gas generation in the sewage conduit 100 even if the operator is not directly injected into the sewage conduit 100, and analyzed quickly According to the results, it is possible to perform appropriate maintenance work on the sewage pipe 100.

FIG. 2 is a view for explaining the sewage pipe 100 of FIG. 1. As described above, the sewage conduit 100 includes a high flow rate conduit 110 and a low flow rate conduit 120, and a cross-sectional view is provided for convenience of description.

Here, D ₁ is the diameter of the high flow rate conduit 110, D ₂ is the diameter of the low flow rate conduit 120. That is, the centers of the high flow rate conduit 110 and the low flow rate conduit 120 are spaced apart by h.

The position v of the contact satisfies Equation 2 below.

[Equation 2]

Here, v refers to the vertical distance from the contact with respect to the lower portion of the high flow conduit 110. The coordinates of the center of the pipe (110) for high flow rate (0, D _1/2) By defining d, y axes to the left are the reference contact (-D _2/2, v) is defined as the right contact (D _2/2 , v).

And, the angle θ with the contact point at the center of the high flow conduit 110 satisfies Equation 3 below.

3 is a conceptual view illustrating an application example of the sewage conduit system having a circular overlapping cross-sectional structure of FIG. 1.

Referring to FIG. 3, a sewage conduit system having a circular overlapping cross-sectional structure includes a plurality of sewage conduits having first to fourth sewage conduits 100-1, 100-2, 100-3, and 100-4 connected in series. The first detector 400-1 is connected to the first sewage conduit 100-1, and the second detector 400-2 is connected to the fourth sewage conduit 100-4. Each of the first detector 400-1 and the second detector 400-2 can detect a running water state of each of the first sewage conduit 100-1 and the fourth sewage conduit 100-4.

Here, the detection results of the first detector 400-1 and the second detector 400-2 are various in the first to fourth sewage conduits 100-1, 100-2, 100-3, and 100-4. It can be used to analyze the state. Hereinafter, for convenience of explanation, it is assumed that the running water in the sewage conduit flows in the direction of the first sewage conduit 100-1 from the fourth sewage conduit 100-4.

Thus, if no flowing water flows through the first detector 400-1 to the first sewage conduit 100-1, the fourth sewage conduit 100-4 is detected through the fourth detector 400-4. If an increase in hydraulic pressure is detected, this can be analyzed as a clogging phenomenon between the second and third sewage conduits 100-2 and 100-3, and when the hydraulic pressure is analyzed, the second and third sewage conduits ( It is also possible to analyze that a part of the conduit is broken between 100-2 and 100-3) and the flow of water flows to the outside.

And, if flowing water flows to the first sewage conduit 100-1 through the first detector 400-1 and flows to the fourth sewage conduit 100-4 through the fourth detector 400-4. If it is detected that the flow of water does not flow, it can be analyzed that breakage occurred between the second and third sewage conduits 100-2 and 100-3, thereby introducing an unwanted flow of water.

In particular, each of the first sewage conduit 100-1 and the first detector 400-1, and the fourth sewage conduit 100-4 and the second detector 400-2 according to an embodiment of the present invention is illustrated in FIG. As described in 1, the first connecting pipe 310 and the second connecting pipe 320 is connected, the water flow and air conditions in the conduit obtained through the first to fourth sewage conduits (100-1, 100-2, 100-3, 100-4) can be used to analyze many more states.

That is, if flowing water flows into the low flow rate conduit 120 of the first sewage conduit 100-1 through the first detector 400-1, it is detected that the flow of water flows through the fourth detector 400-4. If it is detected that the flowing water or the hydraulic pressure is increased in the high flow rate conduit 110 and the low flow rate conduit 120 of the sewage conduit 100-4, this is the second and third sewage conduits 100-2, 100-. 3) It is possible to analyze that an early stage of clogging was formed in between.

Then, if the hydrogen sulfide gas content in the first sewage conduit 100-1 is detected through the first detector 400-1, and the hydrogen sulfide in the fourth sewage conduit 100-4 is detected through the second detector 400-2. When the gas content is detected, it is possible to analyze the source of hydrogen sulfide gas between the second and third sewage conduits 100-2 and 100-3.

As a result, the sewage conduit system having a circular overlapping cross-sectional structure according to an embodiment of the present invention is capable of analyzing the internal condition of a plurality of sewage conduits, and accordingly, it is possible to quickly start an appropriate maintenance work according to the analysis state, thereby reducing the management work cost. It is possible.
