Description

Pipe Assembly of Culvert for Seperating Raindrops and Sewage}

The present invention relates to a sewage culvert-attached sewage separation apparatus attached to the sewage culvert to separate and discharge rainwater and sewage, and more particularly, attached to the sewage culvert where rainwater and sewage are joined. The present invention relates to a sewage culvert-type sewage sewage separation device that allows sewage to be separated without being mixed with each other.

In general, municipal sewage treatment can be divided into classification and confluence. In the classification formula, sewage pipes and sewage pipes are separately installed to transfer sewage to a sewage treatment plant, and sewage and sewage are separated and discharged separately. Thus, there is less sediment inflow and easier water quality management and control.

In addition, the confluence type discharges rainwater and sewage through a consolidation type single conduit and discharges them to sewage culverts or sewage conduits. After being collected and transported in the clay chamber, it is purified in the sewage treatment plant and discharged.

However, the combined sewage treatment method as described above has the following problems.

First, as well as sewage as well as the rainwater does not need to be treated together in the sewage terminal treatment plant, there is a problem in that the capacity of the sewage treatment device must be designed large.

Second, because the area of sewage culverts is planned based on rainwater rainwater, it is difficult to secure proper flow rate in Cheongcheon-si, which causes decay and harmful gases and odors due to the accumulation of organic matter, inorganic matter and earth and sand during dry season. Cause civil complaints and pollute the environment.

Third, in case of rain, the sewage discharge increases, and it is transported to sewage treatment plant through the drainage pipe, and the remaining sewage is overflowed from rainwater soil and discharged to public water. Entering it causes problems causing fish death and river pollution.

Accordingly, Utility Model Registration 0184310 (Publication No. 20-1999-0039390) has a sewage blocking block (1) made of waste vinyl in the sewage culvert (C) as shown in FIG. A sewage blocking block for sewers is disclosed.

However, the sewage blocking block for sewage disclosed in Utility Model Registration No. 0184310 separates the inside of the sewage culvert into two spaces, but since the upper part of the sewage blocking block is opened and the two spaces communicate with each other, the sewage and excellentness of the two spaces in rainy weather are excellent. Is mixed with each other over the open upper end of the sewage blocking block is discharged to the outside, there is a problem that the river pollution occurs, there is a problem that can not prevent the odor spread of the sediment deposited in the sewage culvert.

In addition, the sewage blocking block for sewage disclosed in Utility Model Registration No. 0184310 divides the sewage culvert into only two parts, a space in which the sewage flows and a rainwater flows, so that sewage pipes cannot be connected to both sides of the sewage culvert. If sewage pipes are connected to both sides of the culvert, the construction is impossible, or there is a problem that the sewage pipes must be rebuilt so that all the sewage pipes are connected to one wall of the sewage culvert.

In this regard, the present applicant, as disclosed in Patent Registration No. 0733608, to completely solve the above-mentioned problems, completely separates the space in which the sewage flows and the space in which the rainwater flows, so that the sewage and the rainwater can be discharged without mixing with each other. Provides sewage culvert-type sewage sewage separation device that can be installed without structural change even when sewage pipes discharging sewage are connected to both side walls of sewage culverts by securing proper flow rate of city sewage. I've done it.

However, the applicant's registered patent described above is significantly improved in construction and function compared to the design disclosed in Utility Model Registration No. 0184310 mentioned above, and can be easily installed, but there are still some structural disadvantages to further improve it. There is a need.

Such sewage separator according to the present invention provides the following effects.

First, since the sewage separation plate is attached to one side or both bottom edges of the sewage culvert, the sewage culvert can be completely separated and discharged while minimizing the reduction of the passage area of the sewage culvert. Since it is sealed, it prevents the spread of odor of sewage and is effective for health hygiene.

Second, the sewage separation plate is made of a synthetic resin material such as plastic, simply assembled in the sewage culvert, and easily attached by anchor bolts, etc., the construction is very easy, and the construction time can be significantly shortened. In addition, since the sewage separation plate and the sewage induction pipe and the like can be transported and constructed without the need for mobilization of heavy equipment, the workability is excellent, the air is shortened, and problems such as civil complaints are eliminated.

Third, since the inner space of the sewage separation plate is completely separated from the remaining space of the sewage culvert to prevent the mixing phenomenon of sewage and rainwater in the sewage culvert during rainy weather, it is possible to prevent the pollution of the stream and improve the water quality of the water flowing into the sewage treatment plant. There is also an advantage to improve operational efficiency in sewage treatment plants.

Fourth, the cross-sectional area of the flow path formed by the sewage separator is smaller than that of the other parts. Therefore, even when the amount of water is low, the flow of sewage flowing through the flow path formed by the sewage separating plate is fast, thereby ensuring a minimum flow rate. Therefore, a phenomenon in which foreign matters such as soil and sand accumulate on the bottom surface of the sewage flow path hardly occurs, and the space in which the sewage flows is sealed, thereby preventing the spread of odor caused by the sediment and the sewage.

Fifth, since the sewage separation plate can be installed on both sides of the sewage culvert, even if sewage pipes are connected to both side walls of the sewage culvert, it is possible to smoothly discharge the sewage to both sides without making structural changes.

Sixth, in the case of existing cities, sewage and rainwater must be discharged separately, and the sewage culverts that have already been constructed must be demolished and then converted into a complete classification system in which rainwater pipes and sewage pipes are separately installed. It is not applicable in terms of constructability. Therefore, the present invention, which can separate and discharge rainwater and sewage as in the case of constructing the sewage separation plate only by installing the sewage separation plate, can be constructed at a significantly lower cost than the construction cost according to the classification and is very effective in terms of economic efficiency. In the case of construction, it is possible to minimize complaints due to traffic obstacles, and it is highly desirable in terms of environment since there is no waste generated by demolition of existing sewage culverts accompanying construction by classification.
