Non-digging Sewerage treatment contamination sediment dredging and conduit device its manufacturing method

The present invention relates to a sewage pipe odor dredging method using a rotating nozzle, more specifically, to remove the forward / reverse rotary sediment having a forward / reverse rotary injection nozzle rotated by the ejection pressure of the high pressure water supplied from the high-pressure water washing vehicle. It forms a means to remove sediment such as fat, oil and grease stuck to the wall of sewage pipe in one step, and it is equipped with sediment suction and dredging means at the back of reverse rotating sediment removal means to suck water and sediment inside sewage pipe. It is easy to move to dredging vehicle, and separate sediment suction and dredging means from forward / reverse sediment removal means, and then spray cleaning agent, emulsifier and water-based herbicide through forward / reverse spray nozzle to make fat remaining on the wall of sewage pipe The process of decomposing and liquefying organic substances such as At the same time to remove using a rotating nozzle to completely eliminate the roots of the trees to breed in the sewers adhering niche is to provide a sewer odor abatement dredging method.

Generally, various sewage flows into the sewage pipe with rainwater, and sediments such as fat, oil, and grease are fixed on the wall of the sewage pipe. This sediment not only prevents the smooth drainage of the sewer pipe but also during the rainy season or during heavy rains, the water and sewage flow back. Cause. Therefore, when it is confirmed that sediment has accumulated in sewer pipes using observation mechanisms, the institution managing the sewer pipe is dredging to remove the sediment.

Dredging of sewage pipes includes equipment for drilling clogged sewer pipes and equipment for pulling up sediment induced by sewer pipes. As a method for drilling a clogged sewage pipe, a method of injecting ultra-high pressure water into a sediment is used, and a vacuum pump is used as a method of pulling up the sediment stuck to the sewage pipe.

FIG. 7 illustrates a conventional method of dredging a closed sewage pipe. The water spray vehicle 100, the collection vehicle 200, and the water tank vehicle are used to crush and pull up the sludge deposited on the sewer pipe 400. 300) is mobilized. The water spray vehicle 100 is formed with a water pumping device 101 for pumping the water stored in the water tank vehicle 300, for guiding the pumped water to the sewer pipe 400 through the hose 102 Hose reel assembly 104 is formed. At the end of the hose 102 is formed a water spray nozzle 103 is sprayed with water, the water spray nozzle 103 is formed so that the water is sprayed to the rear, the driving force is generated by the sprayed water, By the driving force, the body of the water spray nozzle is configured to move forward through the deposited sludge. That is, when the water spray nozzle 103 in the sludge deposited in the sewer pipe 400 in the forward direction, and then pumped the water stored in the water tank vehicle 300 in the water spray device 101 at high pressure As the water is strongly sprayed to the rear of the water spray nozzle 103, the driving force is generated, and the water spray nozzle 101 is advanced while drilling the sludge of the sewer pipe 400. At this time, the sludge is crushed due to the water injected flows into the sewer pipe 400 along with the injected water is introduced into the manhole 401. After the water spraying device 101 is moved to the target point, the hose reel assembly 104 is operated to force the hose 102 to be wound. In this process, water is continuously sprayed through the water spray nozzle 103. The sludge of the sewer pipe 400 is crushed. The sludge thus pulverized flows to the manhole 401 with water.

As described above, the sludge and water guided to the manhole 401 are loaded into the deposit stack 201 of the collection vehicle 200 by the suction operation of the vacuum pump 202.

However, in the related art, a washing device for spraying water and a dredging device for sucking sediment are installed in different vehicles, and a cost required for dredging sewer pipes is required because a separate water truck is required to supply water sprayed into the water spray nozzle. And the labor was consumed a lot of disadvantages.

Moreover, if the sedimentation occurs in sewage pipes, the sewage pipes, which had been kept horizontal to 100 ~ 150m in length, have a lot of difficulty in cleaning work.In particular, even if the inside of curved sewage pipes are washed with high pressure water, Water and sediment accumulate, which makes it difficult to clean. Therefore, sediment is cleaned by inserting and pulling a separate jig into the sewer to remove the remaining water and sediment. Therefore, the jig is not smooth, the curved portion and the jig is not in close contact with the remaining water and sediment is a problem that does not clean the cleaning work is a cause of odor occurs.

In the case of the conventional cleaning operation, the sediment flowing into the hose by the suction operation of the vacuum pump is discharged into the sediment stacker of the collection vehicle by spraying the high pressure water to the curved sewage pipe to push out the water and the sediment. Excessive high-pressure water is injected to push out the sediment of the curved sewer pipe, and as a result, more high-pressure water is generated than the sediment, so that the high-pressure water is sucked more than the sediment in loading the sediment in the actual collection vehicle.

This conventional cleaning and dredging work is inconvenient to repeatedly perform a number of operations to remove the water and sediment accumulated in the curved sewer pipe and additional to remove the remaining water and sediment using a separate equipment The work is in progress, but the result is inadequate, which causes a lot of workforce, time and maintenance costs are excessively consumed.

In addition, in the case of the conventional washing and dredging operations, there is a problem in that odors are continuously generated because the remaining sediments such as protein, organic matter such as fat, etc. remaining on the wall of the sewage pipe are not completely removed.

On the other hand, in recent years, the injection device is used to remove the deposit while the injection nozzle is rotated by using the injection pressure of the high pressure water, but a separate equipment and working manpower to load the high pressure water injected from the injection device in the dredging vehicle takes a problem And, there is a problem that the construction cost is excessive because the separate equipment and manpower and time to completely remove the remaining sediment such as oil and grease remaining on the sewer pipe wall.

The conical holder is protruded to the front of the sediment inlet, so that the sediment inlet prevents the sediment inlet from colliding with the curved sewer while maintaining the equilibrium with the sewer. It is to provide a reduced dredging method.

Another object of the present invention is the guide member installed in the forward / reverse rotation nozzle is formed in a plurality of frames in a spherical shape is fixed integrally to the support and the fixture so that the inside penetrates the impact when colliding with the wall surface of the sewer pipe It is to provide a sewer pipe odor dredging method using a rotating nozzle to be absorbed, and to maintain the center of gravity without passing the sewage suction port collides with the sewer pipe wall when the sewer pipe is bent "a".

Another object of the present invention is to inhale the sediment inside the sewage pipe immediately without performing additional dredging after the sediment, such as fat, oil and grease fixed to the sewer pipe wall using high pressure water is completed. By inserting dredging means integrally, water and sediment are sucked into suction channel of sediment inlet and stored in vacuum tank of dredging vehicle.In this step, sediment suction port is equilibrated with sewer pipe even if conical holder is inclined along sewage pipe during movement of curved sewer pipe. The conical holder formed on the front of the sediment suction inlet maintains the state and facilitates the suction of the sediment inlet, while providing a dredging method for reducing the odor of the sewer pipe using a rotary nozzle which allows the sewer pipe to be moved quickly while maintaining the center of gravity of the sediment inlet. .

After the preparation steps of the forward / reverse sediment removal means (A) (B) and the rotation means (C) and the sediment suction and dredging means (D) are completed, devices are introduced into the sewer pipe (1) to the sewer pipe (1). Sediment removal step to remove the sediment stuck to the wall,

The process of removing sediment (2) such as fat, oil and grease stuck to the sewer pipe (1) is divided into two stages, but the first stage is to operate the high pressure water washing vehicle (10) to operate the high pressure water hose (11). The forward rotation nozzle No. 20 and the reverse rotation injection nozzle 21 are rotated in opposite directions by the high pressure water supplied to the high pressure water hose 11 while moving to the front along the guide roller 39. 2) is removed, and the dredging vehicle 35 is operated in this step so that the sediment transfer hose 40 moves along the guide roller 39 into the sewer pipe 1 and the sediment suction port of the sediment suction and dredging means D. Water 30 and sediment 2 accumulated in the sewer pipe 1 are sucked together and loaded into the vacuum tank 36 of the dredging vehicle 35.

In particular, the sediment (2) of the bottom surface of the curved sewage pipe (1) remains unremoved, resulting in the inconvenience of having to repeatedly perform the cleaning and dredging operations and the maintenance cost. There is a problem that takes a lot, and the situation that the additional work using the jig or sponge, etc. due to the failure to remove the remaining sediment only by cleaning and dredging work, but the present invention can solve all such conventional problems. The rotating means (C) is connected between the forward and reverse rotation sediment removal means (A) and (B) rotated by the ejection pressure of the high pressure water so as to rotate in the opposite direction and remain on the wall surface of the sewer pipe (1). Dredging vehicle on the back of the reverse rotation sediment removal means (B) to quickly remove the sediment (2), such as fat, oil, grease, and to remove the sediment (2) to the outside quickly ( A sediment suction and dredging means (D) connected to 35 may be provided to remove the sediment and at the same time water and the sediment may be loaded into the vacuum tank 36 through the suction channel 34 of the sediment suction port 30. The process of removing and loading sediment in one work process can be performed quickly, saving work time and manpower, saving construction cost, and carrying out a separate process of loading sediment together. It can be omitted, in particular, by removing the internal moisture of the sewage pipe (1) by the suction air flowing into the sediment suction port 30 to maintain a natural dry state to more quickly perform the task of coating the cleaning agent and emulsifier on the wall of the sewage pipe There are features that can be done.

In addition, the process of removing sediment in the sewer pipe (1) and the device for removing odors and residual sediments such as fat, oil, grease, and protein remaining on the wall of the sewer pipe (1) can be used as both. One feature is to reduce the cost of manufacturing a separate device.
