Description

{A device of manhole fill-up type water diverting}

The present specification relates to a manhole sewer pipe turning device, and more specifically, natural discharge for bypassing the maintenance section to the ground when dredging sediments accumulated in the sewer pipe between the manhole and the manhole or repairing a damaged sewage pipe due to deterioration. The present invention relates to a water return device for manhole sewage pipes which can be used in combination with a forced and pumping type.

Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application and is not admitted to be prior art by inclusion in this section.

In general, sewage pipes buried in the ground to transfer waste water or sewage to a sewage treatment plant are mainly made of concrete, and the cross-section is formed in a circular or rectangular shape.

The sewage pipe buried in the ground progresses with age, and cracks or holes are generated due to impact, and water or industrial sewage transported along the sewage pipe due to expansion or contraction of the fastening member leaks through the cracks or damaged areas. If it flows into the ground, it can cause serious contamination of groundwater or soil.

Due to this, the relevant sewer pipe is excavated to construct or repair the sewer pipe.

When sediments such as soil and sludge are accumulated in the above-described sewage pipe, dredging is required to remove them. At this time, for the maintenance work or dredging work of the sewer pipe, equipment is inserted into the sewer pipe through a manhole or an operator directly enters the sewer pipe through the manhole.

As described above, prior work is required to repair the inside of the sewage pipe or to dredge sediments such as soil and sludge therein. In other words, the sewer pipe muddol, which measures to bypass the sewage flowing along the buried pipe, will be constructed, and it will be used for various non-drilling construction or work such as non-drilling construction or CC-TV shooting to repair the underground pipe. First of all, it is almost essential.

Recently, for the repair of pipelines, instead of the excavation works of excavating soil and soil by using heavy equipment, non-excavation works that can repair pipelines without excavating soil and rupture the presence of pipelines and identify the exact location where repairs are necessary CC-TV shooting to do this is actively being used.

The above-mentioned non-drilling construction and CC-TV shooting are more likely to damage roads as well as damage to communication cables, power cables, and city gas pipes buried underground while heavy equipment such as excavators is used. As compared with many risks, the most of the problems caused by excavation can be solved, which is a trend that is rapidly increasing mainly in urban areas or new town residential development sites.

1 is a view for explaining a water turning method according to the prior art.

As shown in the figure, according to the conventional water turning method, the manholes M1 and M2 are interposed, and the upstream side pipe P2, the middle pipe P1, and the downstream side pipe P3 are sequentially from the upstream side to the downstream side. When connected to, a large water pump (1) is installed on the ground and a water return hose (2) is installed so as to pass through the ground before and after the water pump (1).

Accordingly, the water pump 1 is operated to pump sewage (W) through the upstream manhole (M1) and pump it up to the ground, and then perform water turning as it is discharged through the manhole (M2) located on the downstream side. Could.

As described above, the conventional water turning method uses a large water pump 1 that consumes a lot of power and is inconvenient to move, and has a problem in that complaints from nearby residents are raised due to noise caused by the operation of the water pump 1.

In addition, as the amount of sewage that can be pumped and pumped by the water pump (1) is limited, it is possible to return water to small pipelines that do not have a large amount of sewage (W), whereas in medium and large pipelines where there is a large amount of sewage It becomes difficult to turn the water.

2 to 5, a manhole sewer pipe turning device capable of being used in combination according to an embodiment of the present specification

Bypass the maintenance section 14 located between the first manhole 11 to which the first conduit 10 is connected from the upstream direction and the second manhole 13 to which the second conduit 12 is connected in the downstream direction It is applied to the manhole sewer water turning device for turning water,

It is detachably mounted to open and close the inlet of the maintenance section 14 and flows along the first conduit 10 to the inlet of the first manhole 11 by hydraulic pressure flowing into the first manhole 11. Air packer 15 for guiding to fill up;

The main body 18 which is detachably mounted to open and close the inlet of the first manhole 11, and is formed with a sewage inlet 16 and a sewage outlet 17 through which sewage flowing in and out of the first manhole 11 flows in and out );

The inlet is connected to the sewage outlet 17 so as to communicate, and the outlet is accommodated inside the second manhole 13, and the inlet height of the second manhole 13 is the same or lower than the inlet height of the first manhole 11 A first water return hose 19 for conveying the sewage discharged through the sewage discharge port 17 to the second manhole 13 in a self-weighting method;

A pump 20 having a suction port branched to the upstream side of the first water return hose 19;

Sewage when the inlet is connected to the outlet of the pump 20 and the outlet is accommodated inside the second manhole 13, and the inlet height of the second manhole 13 is higher than the inlet height of the first manhole 11 And a second water return hose 21 for pumping the sewage discharged through the outlet 17 by the pump 20 to the second manhole 13.

At this time, more preferably, the above-described first and second water return hoses 19 and 21 are flexible pipes that are free from bending regardless of the transport length according to the site conditions in transporting sewage, and are made of polyester-based fibers. It may be selected and formed of either woven or non-woven fabric.

In addition, the first and second water return hoses 19 and 21 may be formed to stack polyvinyl, polyurethane, and polyurethane film layers in one or more layers for watertight maintenance and strength reinforcement, and reinforced cotton fibers (glass Fiber).

It is further provided with an opening / closing valve 22 mounted on one side of the aforementioned sewage discharge port 17 to open and close the internal passage.

The on-off valve 22 is a knife gate valve that selectively opens and closes the internal passage of the sewage outlet 17 while advancing across the sewage outlet 17, and is turned on when an electrical signal is applied from the outside. A solenoid valve that switches and closes the internal passage, or a lever-type opening and closing valve capable of manually opening and closing the internal passage may be used, and these are technical details used in the art, so detailed description of their configuration Is omitted.

The second water return hose (21) is installed on one side and pumped by the pump (20) to temporarily store and discharge the sewage tank for adjusting the flow rate and flow rate of one or more sewage tanks (23) ); Is further provided, the opening and closing valve 25 is mounted to the outlet (not shown in the drawing) formed in the lower portion of the sewage tank 23 for controlling the flow rate and flow rate.

The above-described on-off valve 25 is a knife gate valve that selectively opens and closes the inner passage of the outlet while advancing across the outlet, a solenoid valve that is switched to the ON state when an electrical signal is applied from the outside, or a solenoid valve to manually close the outlet. A lever-type on-off valve capable of opening and closing the discharge port may be used, and since these are technical details used in the art, detailed descriptions of their configuration will be omitted.

The main body 18 is further provided with an air outlet 26 for inhaling or discharging external air; however, a stopper 27 is attached to the air outlet 26 to be opened and closed.

That is, when the sewage in the first manhole 11 rises and exits, air is discharged or sucked through the open air outlet 26, while air is closed by the stopper 27 when the sewage is diverted. Through the outlet 26, it is possible to prevent the sewage from being discharged to the outside unnecessarily.

It is mounted on the seating groove 28 formed on the lower outer periphery of the main body 18, and is in close contact with the inside surface of the inlet of the first manhole 11 to further seal the coupling gap.

The aforementioned packing member 29 is

When compressed air is supplied from the air compressor (AC), it is expanded upon injection through the injection pipe 30 to fix the main body 18 at the entrance of the first manhole 11, and compressed air to the outside through the injection pipe 30 A ring-shaped air packing that is contracted upon discharge and capable of detaching the body 18 from the first manhole 11 is used.

That is, when compressed air is injected into the packing member 29 through the injection pipe 30 from the air compressor AC, the packing member 29 expands to strongly press the inner circumferential surface of the inlet of the first manhole 11. At this time, the sealing gap between the main body 18 and the inlet of the first manhole 11 is sealed by the expansion pressure of the packing member 29.

On the contrary, when the compressed air of the packing member 29 is discharged to the outside through the injection pipe 30, the packing member 29 is contracted and the gap between the main body 18 and the entrance of the first manhole 11 is reduced. The confidentiality is released. Therefore, the main body 18 in which the packing member 29 is mounted in a contracted state can be detached from the first manhole 11.

Since the packing member 29 that expands in the form of a tube when injecting compressed air from the above-described air compressor (AC) through the injection tube 30 and contracts to an initial state when the compressed air is discharged, these are used in the art. Detailed description of the configuration is omitted.

In the drawings, reference numeral 31 denotes a shoring that is installed at the entrance of the maintenance section 14. As the air packer 15 is connected to the shoring neck 31 by a wire 32, the air packer 15 is discharged by sewage. It serves to hold it so that it does not drift downstream, and is formed in a lattice structure so that the sewage passes.

Thereby, the prop 31 is held by the wire 32 so as not to let the air packer 15 float by the sewage while allowing sewage flow from the first conduit 10 to the maintenance section 14.

On the other hand, even when the air packer 15 expands in the form of a ball by injecting compressed air and seals the opening of the maintenance section 14, it does not resist the pressure of the sewage that rises inside the first manhole 11 and maintains little by little. It can be pushed toward the maintenance section 14. Due to this, it is impossible to sufficiently secure the construction time of the maintenance section 14.

Hereinafter, an example of use of a manhole sewer pipe turning device capable of being used in combination according to an embodiment of the present specification will be described in accordance with the accompanying drawings.

A) It explains how to divert the sewage from the sewage pipe to the ground so that it can work in the maintenance section.

2 to 4, the old or damaged sewage pipe of the above-described maintenance section 14 can be repaired, replaced, or dredged in the maintenance section 14 can be dredged from the upstream direction. In the case of turning the water by bypassing the maintenance section 14 located between the first manhole 11 to which the first conduit 10 is connected and the second manhole 13 to which the second conduit 12 is connected in the downstream direction to the ground. , According to the ground environment of the first manhole 11 and the second manhole 13, it is possible to turn the water by non-power.

In detail, air is discharged and installed at the entrance of the maintenance section 14 by interconnecting the contracted air packer 15 and the strut 31 by wires 32, at this time, the air packer 15 ) Is connected to the strut 31 by the wire 32 even when the sewage flows in the maintenance section 14, so that even when the air packer 15 is contracted, it does not drift to the downstream side by the sewage.

The lower end of the above-described main body 18 is inserted into the inlet of the first manhole 11, but from the air compressor AC to the packing member 29 mounted on the seating groove 28 formed in the outer periphery of the main body 18. The compressed air supplied through the air hose is injected by the injection pipe (30). That is, due to the expansion of the packing member 29, the coupling gap between the main body 18 and the entrance of the first manhole 11 can be sealed.

The one end of the first water return hose 19 is connected to the sewage outlet 17 of the body 18 so as to communicate, and the other end of the first water return hose 19 is accommodated inside the second manhole 13.

In addition, as the compressed air supplied from the air compressor (AC) through the air hose 24 is injected into the air packer 15, the air packer 15 expands to expand the air packer 15 and the maintenance section 14 The gap between the openings can be sealed.

Since the air packer 15 that expands by the compressed air injected from the air compressor 24 through the air hose 24 and fills the inlet side of the maintenance section 14 is the technical content used in the art, The detailed description of these structures is omitted.

Therefore, the sewage flowing from the upstream and flowing through the first conduit 10 fills up inside the first manhole 11. At this time, the air outlet 26 of the main body 18 is switched to the open state so that the air remaining inside the first manhole 11 can be discharged to the outside as the sewage rises inside the first manhole 11.

At this time, when the sewage flowing into the first manhole 11 reaches the sewage outlet 17 of the body 18, the stopper 27 is closed by closing the air outlet 26. Due to this, the sewage filling up inside the first manhole 11 is prevented from leaking to the outside through the air outlet 26, and thus can be discharged through the sewage outlet 17 of the main body 18, and the sewage outlet 17 The passing sewage can be transferred to the second manhole 13 through the first water return hose 19.

At this time, as shown in FIG. 4, when the inlet height of the second manhole 13 is equal to or lower than the inlet height of the first manhole 11, the sewage discharged through the sewage outlet 17 is non-powered. By doing so, it is possible to transfer the second manhole 13 along the first water return hose 19 in a self-weight flow method.

That is, when the water is returned by bypassing the maintenance section 14 to the ground, the sewage flowing into the first manhole 11 is caused by a difference in the inlet height of the first manhole 11 and the inlet height of the second manhole 13. As the water is returned to the second manhole 13 by filling up, it is unnecessary to use a power source such as a water pump.

As described above, the sewage flowing from the upstream and flowing into the first manhole 11 along the first pipeline 10 can be turned around by bypassing the maintenance section 14 to the ground. That is, as the sewage flowing into the first manhole 11 flows naturally in a self-weight flow method along the first water return hose 19 and bypasses the second manhole 13 ) To bypass the water.

By bypassing the maintenance section 14 to the ground and turning the water, the maintenance section 14 can repair or replace the old or damaged sewage pipe, or dredge sediments.

On the other hand, when the predetermined work is completed in the maintenance section 14, the draining of the sewage filling the first manhole 11 can be completed.

After separating the stopper 27 coupled to the air outlet 26 of the main body 18, the air outlet 26 is opened and the compressed air is discharged from the air packer 15.

Due to this, the air packer 15 is switched to the contracted state, and the entrance of the maintenance section 14 is opened, so that the sewage filling up inside the first manhole 11 passes through the strut 31 to the maintenance section 14 Flows down

That is, the level of the sewage filling the first manhole 11 is lowered than the sewage outlet 17 of the main body 18, and the water turning operation ends. At this time, even if the sewage inside the first manhole 11 passes through the entrance to the maintenance section 14 at a high speed, the air packer 15 flows along the sewage because it is connected to the prop 31 by the wire 32. It is prevented from going down.

When the water turning operation is completed by bypassing the maintenance section 14 to the ground as described above, the compressed air is discharged through the injection pipe 30 from the packing member 29 to switch to the contracted state, thereby converting the first manhole ( 11) Separate the main body 18 from the inlet. Thereafter, compressed air is discharged from the air packer (15) installed at the entrance of the maintenance section (14) to separate the strut (31) and air packer (15) from the maintenance section (14) to the first manhole (11) outside. Lift.

B) It explains how to increase the amount of drainage by diverting the sewage from the sewage pipe to the ground by the pump so that it can work in the maintenance section.

2, 3 and 5, the maintenance section (so as to perform a predetermined operation (old or damaged sewage pipe replacement work, sediment dredging work, etc.) within the aforementioned maintenance section 14 In the case of turning the water by bypassing 14) to the ground, it is possible to increase the displacement by the pump 20 to turn the water.

At this time, the main body 18 and the packing member 29 which are detachably mounted to seal the entrance of the first manhole 11, and the strut 31 which is detachably mounted to seal the entrance of the maintenance section 14 And having an air packer 15, the configuration that discharges the sewage flowing through the first conduit 10 through the sewage outlet 17 of the main body 18 to fill the first manhole 11,

Since the above-described difference in the height of the entrance of the first manhole 11 and the height of the entrance of the second manhole 13 bypasses the maintenance section 14 to the ground, it is substantially the same as the configuration used for turning the water. Detailed description of the configuration and use of is omitted.

In the following, it will be described in detail to increase the displacement by the pump 20 when turning the water by bypassing the maintenance section 14 to the ground.

As shown in FIG. 5, in the case of a ground condition in which the inlet height of the second manhole 13 is higher than the inlet height of the first manhole 11, the sewage discharged from the sewage outlet 17 of the main body 18 is self-weighted. It is impossible to transfer the second manhole 13 inside the flow method.

At this time, pumping the sewage discharged from the sewage discharge port 17 by a pump 20 with a suction port branched to the upstream side of the first water return hose 19 connected to the sewage discharge port 17 of the main body 18, The pumped sewage is discharged to the second manhole 13 through a second water return hose 21 connected to the outlet of the pump 20 so that the inlet communicates with the outlet inside the second manhole 13.

As described above, when the entrance height of the second manhole 13 is higher than the entrance height of the first manhole 11, it is a condition in which sewage cannot be transferred into the second manhole 13 in a self-weighting method. Edo, the first pipeline (10)-the first manhole (11)-the sewage discharged through the sewage outlet (17) of the body 18 in turn through the pump (20) and the second water return hose (21) 2 It can be transferred to the manhole (13).

Therefore, in the case of a ground environment in which the inlet height of the second manhole 13 is higher than the inlet height of the first manhole 11, the sewage discharged through the sewage discharge port of the main body after entering the first manhole 11 and filling the inlet side Repair work to repair or replace old or damaged sewage pipes in the maintenance section 14 as the amount of water to be transferred to the second manhole 13 is increased through the second water return hose 21, or soil, sludge It is possible to shorten the working time of installing the water turning device in order to dredge the sediment containing the back in the maintenance section 14.

Here, although the above-described specification has been described with reference to preferred embodiments, those skilled in the art variously modify the specification without departing from the spirit and scope of the specification as set forth in the claims below. You will understand that you can change it.
