Description

Technology Field

[0001] The present invention relates to a sewer pumping pipe structure equipped with a bypass pipe for air discharge, and more specifically, to a sewer pumping pipe structure equipped with a bypass pipe for air discharge that allows for efficient prevention of water hammer within the pumping pipe while reducing construction and maintenance costs of the sewer pipe by piping a movement path at the top of the sewer pumping pipe toward the downstream end to enable air discharge. Background Technology

[0003] Generally, a sewer pipe is a pumping facility that transports various types of wastewater (hereinafter referred to as "sewage"), such as domestic wastewater from households and restaurants, self-purified industrial wastewater, and rainwater combined through stormwater pipes, to a sewage treatment plant.

[0005] Although sewage in sewer pipes, which are pumping facilities, was primarily transported by gravity flow, there are many cases where a pressure transport method is inevitably adopted instead of gravity flow due to topographical issues during sewer pipe construction. In other words, if only gravity flow is used for sewer pipe construction, the excavation depth becomes too deep depending on the terrain, making construction difficult or resulting in excessive construction costs. Therefore, pumping stations are installed in the middle of the facility to install and use a pressure transport pipeline.

[0007] As such, in order to efficiently operate a sewer pipe structure equipped with a pressure pipeline, it is necessary to expel air from within the pipe. Specifically, an air valve is installed and configured to rapidly expel air from within the pipe and sequentially block water outflow when filling it with water, thereby enabling the rapid and efficient operation of water flow or drainage.

[0009] At this time, the purpose of installing an air valve is to exclude or draw in air from within the pipe. In the longitudinal section of the pipeline, air dissolved in the water is released and accumulates at the top of the upward protrusion, forming an air pocket. If this air pocket is not removed, it reduces the cross-sectional area for water flow, hindering smooth water flow and sometimes causing pipeline accidents; therefore, it must be properly and automatically excluded. Furthermore, when laying pipes or refilling water after shutting off the water supply, the pipe must be filled while excluding air. Also, when shutting off the water supply and draining the water from the pipe during construction or as needed for work, the inside of the pipe becomes close to a vacuum, raising concerns that the pipe may deform due to external pressure. In such cases, to prevent pipe deformation, air must be automatically drawn into the pipe. To achieve this purpose, an air valve must be installed at an appropriate location in the pipeline.

[0011] Looking at the operation method of the air valve, the air valve contains a ball inside, configured to move vertically according to the water level in the valve chamber. At this time, when there is air inside, the ball descends and the air escapes through the hole in the air valve, and the water in the pipe rises due to pumping. When water enters the valve chamber, the ball rises due to buoyancy, and with the air expelled, it blocks the hole in the air valve to prevent fluid leakage in the pipe.

[0013] As prior art disclosed in relation to air valves applied to sewer pipes as described above, Korean Registered Utility Model Publication No. 239926 (July 13, 2001) describes an air valve used in a sewer system, wherein the air valve has an upper body fixed to a lower body on which a ball valve is installed, with an intermediate partition inserted between the upper and lower bodies, a seat cover fixed to the upper part of the upper body, a seat body fastened to the inner lower part of the seat cover, a float fixed to the seat body, a small air hole inserted to the upper part of the float, a small air hole seat inserted to seal the inner lower part of the float, a seat plate inserted and fixed to the inner part of the small air hole seat, a float rod fixed and fastened to the seat plate, a spring fastened to the outer side of the float rod, a float ball fixed to the end of the float rod, a ball seat fastened to the lower inner part of the seat body, a float seat inserted to the upper inner part of the seat cover, and an exhaust port on the seat cover to be inserted into the float seat. A multi-sealed air valve for sewers is known, which can maximize the effectiveness and efficiency of the valve by blocking water from leaking out through a configuration in which a formed exhaust port cover is inserted and fixed.

[0015] In addition, Registered Patent Publication No. 0884731 (February 13, 2009) discloses an air valve for a sewer system that is simple in structure, inexpensive, minimizes manufacturing defects, and can fundamentally prevent environmental pollution. It comprises a first housing having a flange on the upper edge and an inlet for water to flow in a vertical direction downward, and a second housing positioned above the first housing having different flanges on the lower and upper sides, respectively, in a position opposite to the flange. A ball is provided inside to discharge and block air by the buoyancy of water flowing in through the sewer pipe, and an air vent valve that discharges air when a water pressure higher than a predetermined pressure is applied.

[0017] However, when an air valve is applied to a sewer pumping pipe as in the aforementioned conventional technologies, foreign substances often accumulate on the surface of the ball inside the valve due to the high viscosity of the wastewater passing through the valve along with foreign substances. Furthermore, if foreign substances adhere to and accumulate around the ball inside the valve, it hinders the up-and-down movement of the ball, leading to frequent malfunctions such as wastewater leakage. Moreover, if a strainer is installed at the bottom of the valve, maintenance is difficult because the strainer must be cleaned frequently, and poor maintenance of the valve leads to functional failure of the pumping pipe.

[0035] Next, a preferred embodiment of a sewer pumping pipe structure equipped with an air discharge bypass pipe according to the present invention will be described in detail with reference to the drawings.

[0037] First, an embodiment of a sewer pumping pipe structure having an air discharge bypass pipe according to the present invention is formed by including a sewer pumping pipe (10) and an air bypass pipe (20), as shown in FIG. 1.

[0039] The above sewage pressure pipeline (10) is constructed to be continuously piped underground, and is configured to form a transport flow path for sewage fluid, thereby forming a waterway to a public sewage treatment facility.

[0041] The above sewage pressure pipeline (10) is constructed by connecting it along the longitudinal direction toward the sewage transport path, and is configured to have an uppermost part (a1) in the upstream terrain and a downstream part (a2) in the downstream terrain according to the construction terrain of the pipeline.

[0043] The above sewage pressure pipeline (10) is configured with connecting nipples (15a) and (15b) to enable connection to the above air bypass pipeline (20).

[0045] The above connecting nipples (15a) and (15b) are configured to connect one end or the other end of the air bypass pipe (20) to the sewage pressure pipe (10). That is, they are configured to connect both ends of the air bypass pipe (20), namely one end or the other end of the air bypass pipe (20), to the sewage pressure pipe (10), respectively, at the uppermost part (a1) and the downstream part (a2) of the sewage pressure pipe (10).

[0047] Although not shown in the drawing, the sewage pressure pipe (10) is formed with an exhaust hole and an organic hole. That is, it is configured to have an exhaust hole formed to allow air to be discharged corresponding to the connecting nipple (15a) at the uppermost part (a1) of the sewage pressure pipe (10), and an organic hole formed to allow air to be introduced corresponding to the connecting nipple (15b) at the downstream part (a2) of the sewage pressure pipe (10).

[0049] In the sewage pressure pipeline (10), the connection point of the downstream section (a2) where the air bypass pipeline (20) is connected at one end is configured to be a point where the water pressure of the fluid is greater than the rising pressure of the air, thereby enabling smooth air flow from the uppermost section (a1) of the sewage pressure pipeline (10).

[0051] The above air bypass pipe (20) performs the function of forming an extended air transport path that enables the discharge and transport of air generated within the above sewage pressure pipe (10).

[0053] The air bypass pipe (20) is installed by connecting both ends to the sewage pressure pipe (10), with one end connected to the uppermost part (a1) of the sewage pressure pipe (10) and the other end connected to the downstream part (a2) of the sewage pressure pipe (10). That is, one end of the air bypass pipe (20) is connected to a connecting nipple (15a) corresponding to the exhaust hole at the uppermost part (a1) of the sewage pressure pipe (10), and the other end of the air bypass pipe (20) is connected to a connecting nipple (15b) corresponding to the exhaust hole at the downstream part (a2) of the sewage pressure pipe (10).

[0057] The above air bypass pipe (20) is structured to discharge air generated at the uppermost part (a1) within the sewage pressure pipe (10). By means of a suction operation occurring in the air bypass pipe (20) at the downstream part (a2) of the sewage pressure pipe (10), the air generated at the uppermost part (a1) of the sewage pressure pipe (10) is discharged and transported, thereby offsetting the maximum negative pressure generated at the uppermost part (a1) of the sewage pressure pipe (10) and preventing water hammer within the pipe.

This allows for the simultaneous installation of the bypass pipe during the laying of the pumping pipe, as well as the elimination of the need for a separate air valve and valve chamber, thereby reducing construction costs. Furthermore, it eliminates the need for separate maintenance, thereby facilitating pipe maintenance and preventing defects. Additionally, it is possible to resolve the difficulties associated with installing valve chambers even in urban areas with many obstacles, and improve constructability due to the absence of an air valve chamber.
