FIG. 3 is a cross-sectional view of a bypass apparatus for a tail pipe according to the present invention, and FIG. 4 is a cross-sectional view of a by-pass pipe according to another embodiment of the present invention. Fig.

As shown in FIGS. 1 to 4, the present invention is characterized in that, in order to repair the secondary pipe between the second manhole and the third manhole or to dred the sludge, the present invention is provided in a differential structure between the first manhole and the second manhole, The present invention relates to a by-pass device for bypassing a first manhole by bypassing a bypass pipe by shutting off the flow of fluid in a sub- When the internal water level rises, the pump senses the water level, intermittently forcibly bypasses the fluid through the pump, increases the efficiency of the pump, and operates the pump to lower the hydraulic pressure of the fluid, thereby securing the stability of the bypass device installed in the subassembly And a bypass device 100 for a subassembly.

The bypass apparatus 100 for a subassembly includes a body 10, an expansion tube 12, a fluid shutoff plate 20, first, second and third connectors 30, 40 and 13, (31) and a drain pipe (41).

The body 10 has a cylindrical shape so that it can be inserted into the first manhole 301 and inserted into the second housing 200.

At this time, the body 10 has a flexible joint 11 formed therein to facilitate entry into the subassembly 200 and to be installed in a curvature portion of the subassembly 200.

Here, the joint 11 may be formed of any one of woven synthetic fiber or synthetic resin or synthetic resin corrugated tube.

The expansion tube 12 is configured to be enclosed in the body 10. The expansion tube 12 is expanded when air is supplied to seal the space between the body 10 and the subassembly 200 to prevent leakage of the fluid, 10) can be fixed within the secondary container 200. [0053]

The fluid blocking plate 20 is coupled to one end of the body 10 so as to block the flow of fluid in the sub-pipe 200.

At this time, the first connector 30 is formed in the lower portion of the fluid shutoff plate 20 so as to allow the fluid in the sub-container 200 to be drained by water pressure.

The first connector 30 is connected to a bypass pipe 31 through which the fluid that is naturally discharged is bypassed to the third manhole 303.

A second connector 40 is connected to the upper portion of the fluid shutoff plate 20 so as to allow the fluid to be forcedly drained in the secondary pipe 200. A drain pipe 41 is connected to the pump 42, So that the fluid in the secondary collector 200 can be bypassed to the third manhole 303 for forced discharge.

Here, when the amount of fluid flowing into the secondary pipe is larger than the amount of fluid discharged through the bypass pipe 31, the operation of the pump 42 is intermittently operated to prevent the backflow of the fluid to the first manhole 301, .

To this end, the first manhole 301 is provided with a water level sensor 60 for measuring the internal water level when the internal water level is increased due to a large amount of fluid flowing into the secondary pipe than the amount of fluid discharged through the bypass pipe 31 .

When the internal water level of the first manhole 301 becomes high, the water level sensor 60 is connected to the controller 70 through a wireless or wire line, The pump 42 is operated through the first manhole 301 and the pump 42 is stopped when the water level in the first manhole 301 is lowered. As a result, the pump 42 can be efficiently operated.

The guide pipe 13 is connected to the first connector 30 so as to guide the fluid to the inside of the body 10.

Even if the pump 42 is operated, the guide pipe 13 functions to allow a part of the fluid to flow into the guide pipe 13 without being interfered with the suction force of the pump 42, thereby allowing the guide pipe 13 to be naturally drained.

In addition, the guide pipe 13 can be configured so that the free end thereof is expanded to allow the inflow of the fluid.

Meanwhile, the valve body 50 is connected to the first connector 30 and the second connector 40 so as to selectively block the flow of the fluid.

A connecting bar 15 is provided at the other end of the body 10 to pull the body 10 out of the first manhole 301.

The connection bar 15 is formed in a cross shape so as not to interfere with the fluid so as to be coupled to the inner circumferential surface of the body 10 and a connection ring 151 connected to the second wire 82 at the intersection .

The second wire 82 functions to adjust the position of the body 10 and to pull the body 10 when the body 10 is taken out to the outside.

A third connector 14 for supplying compressed air to the expansion tube 12 is formed on the body 10 and the third connector 14 is connected to the body 10 to allow the body 10 to enter the interior of the secondary pipe 200 It can be used as a coupling port for connecting the first wire 81.

Meanwhile, as shown in FIG. 4, the body 10 may be divided into two halves so as to be screwed to each other.

In this configuration, when the inner diameter of the sub pipe 200 is large, the fluid pressure is increased. When the pressure of the fluid rises, the body 10 is made longer in proportion to the inner diameter of the sub pipe 200.

At this time, the inflation tube 12 is individually housed in each body 10 so that it is not interfered when the distance of the body 10 is adjusted.
In this structure, each expansion tube 12 enclosed in each body 10 is further expanded to the threaded portion to increase the ground contact area. As a result, the frictional force is increased and the body 10 is detached from the secondary tube 200 It is possible to prevent the loss of the apparatus and safety accidents.

In addition, a bypass device 90 for sub-subassembly connected to the bypass pipe 31 and the drain pipe 41 is installed inside the subassembly 200 to prevent backflow of the bypassed fluid.

The bypass apparatus for bypass sub-apparatus 90 has the same structure as bypass apparatus 100 for the sub-apparatus, and a detailed description thereof will be omitted.

However, it is constructed so as to be installed in the inside of the secondary pipe (200) between the third manhole (303) and the fourth manhole (304) to prevent reverse flow of the bypassed fluid. The bypass subassembly 90 is connected to the bypass pipe 31 and the drain pipe 41 of the bypass apparatus 100 for at least two subassemblies by connecting at least two connection connectors 92 are formed.

Hereinafter, the operation of the bypass apparatus for a subcontractor according to the present invention will be briefly described.

5 and 6 are operation diagrams of a bypass apparatus for a subassembly according to the present invention.

As shown in FIG. 5, when the bypass apparatus 100 for a subassembly is installed inside the subassembly 200, the flow of fluid in the subassembly 200 is cut off.

In this state, the water level in the sub-pipe 200 is gradually increased and the water pressure is increased. As a result, the fluid passes through the guide pipe 13, the first connector 30 and the bypass pipe 31, (90).

6, when the amount of fluid flowing into the secondary pipe 200 is larger than the amount of fluid flowing into the bypass pipe 31, the fluid flows back to the first manhole 301 due to the bottleneck phenomenon, The water level sensor 60 senses the sensed water level and sends the sensed value to the control unit 70. The control unit 70 activates the pump 42. [

Then, along with the natural drainage of the bypass pipe 31, the fluid is drained via the sub-drainage bypass device 90 via the pump 42 coupled to the second connector.

Accordingly, it is possible to prevent the backflow of the fluid to the first manhole 301 and prevent the body 10 from being detached from the inside of the secondary pipe 200 due to excessive water pressure, thereby preventing a safety accident.

When the water level of the first manhole 301 is lowered by the operation of the pump 42, the water level sensor 60 senses the level of the first manhole 301 and stops the operation of the pump 42. Therefore, the pump 42 is intermittently operated, As a result, the efficiency of the pump 42 can be increased while preventing the pump 42 from overheating.

Further, since the discharged fluid is not likely to be backwashed by the sub-subassembly bypass device 90, maintenance, reinforcement and replacement of maintenance pipes for maintenance between the first manhole 301 and the second manhole 302, It is possible to prevent safety accidents in construction of this project.

Hereinafter, an installation method of a bypass device for a sub-container according to the present invention will be described.

8, the buoyant body B is connected to the free end of the first wire 81 and the buoyant body B is dropped to the first manhole 301. (S30)

9, the buoyant body B flows along the fluid, thereby lifting the buoyant body B exposed to the position of the second manhole 302 to the outside to secure the first wire 81 (S40)

The body 10 is inserted into the secondary pipe 200 through the first manhole 301 in a state where the second wire 82 is connected to the coupling ring 151 coupled to the other end of the body 10 . (S50)

10, the first wire (81) and the second wire (82) are adjusted outside the first manhole (301) and the second manhole (302) (S60). ≪ RTI ID = 0.0 >

And the compressed air is supplied to the expansion tube 12 through the third connector 14.

Then, as shown in FIG. 11, the expansion tube 12 expands and comes into close contact with the inner circumferential surface of the secondary pipe 200 to fix the body 10. (S70)

12, the valve body 50 is connected to the first connector 30 of the fluid blocking plate 20 and the second connector 40. In operation S80,

Then, the water pipe 41 connected to the bypass pipe 31 and the pump 42 is connected to each valve body 50. (S70)

In order to prevent backflow of the bypassed fluid, a bypass subassembly for bypassing subassemblies is installed in a subassembly between the third manhole and the fourth manhole through steps S10 through S60. (S90)

Finally, the free ends of the bypass pipe 31 and the drain pipe 41 are connected to the bypass device 90 for the sub-subassembly to complete the installation (S100).
