Description

[0001] The present invention relates to a bypass pipe construction structure for a water pipe,

The present invention relates to a bypass pipe installation structure of a new water pipe which can install a bypass pipe without a separate excavation process.

Generally, water pipes are buried underground.

Therefore, when water leakage occurs in such a water supply pipe, or when the water supply pipe is to be replaced due to aging of the water supply pipe, the water supply pipe is replaced by digging the ground.

In the meantime, a manhole-like working hole is formed at regular intervals along the water pipe at the position where the water pipe is buried. In the middle part of the water pipe, a water pipe is provided at a wider interval than the interval of the work pipe, A main valve is provided for controlling the flow of tap water flowing.

The worktable is formed in a deep plate shape so that an intermediate portion of the water supply pipe is exposed inside the worktable.

Therefore, when maintenance of the water supply pipe is maintained, the water supply pipe is maintained in such a state that the main valve located at the front and rear of the maintenance position is closed and water does not flow through the water supply pipe.

However, in such a case, until the maintenance of the water supply pipe is completed, the supply of tap water to the large area is interrupted.

Therefore, in recent years, when maintenance of the water supply system is divided into a rehabilitation unit for maintenance of the water supply pipe and a connection unit connected to both ends of the rehabilitation unit, a bypass pipe for bypassing the rehabilitation unit is connected to the connection unit, There has been developed a method of performing maintenance on the regeneration section while supplying tap water through a bypass pipe.

However, in order to install the bypass pipe as described above, the bypass pipe must be connected to the water pipe by excavating the ground, thereby complicating the operation.

Therefore, there is a need for a new method to solve such a problem.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 illustrate a bypass pipe construction of a water pipe according to the present invention. The water pipe 10 is installed to be embedded in the ground 1, and at a position where the water pipe 10 is embedded A manhole (2) is formed at regular intervals along the water pipe (10).

At this time, the water pipe (10) is provided with a main valve (not shown) spaced apart at a predetermined interval.

The water pipe 10 is divided into a rehabilitation part 11 to be maintained and a connection part 12 connected to both ends of the rehabilitation part 11.

Since the buried structure of the water pipe 10 is the same as that of the conventional art, a detailed description thereof will be omitted.

According to the construction of the bypass pipe of the water pipe according to the present invention, the lower end portion is connected to the connection portion (12) and the upper end is connected to the operation port (2) A pair of extension pipes 20 extending to the upper portion of the extension pipe 20 and having a bypass valve 21 at an intermediate portion thereof and a bypass pipe 20 having both ends connected to the extension pipe 20, An opening and closing valve 50 provided at an end of the connecting part 12 to open and close an end of the connecting part 12; And a fixing table 40 for fixing the bypass tube 30 to the paper surface 1.

The extension pipe 20 is made of a metal material having a high strength and is provided inside the work port 2 located at both ends of the rehabilitation unit 11 so that the lower end thereof is connected to the water pipe 10, Is connected to the circumferential surface of the body by the end hydraulic method.

In the above-described end-tapped water treatment method, a lower end of the extension pipe 20 is welded to the circumferential surface of the connection portion 12, and a drill is inserted into the extension pipe 20 to form a through hole at the periphery of the connection portion 12 The extension pipe 20 can be welded to the upper surface of the connection portion 12 in a state where tap water is supplied through the water pipe 10.

At this time, the upper end of the extension pipe 20 is bent to extend in the lateral direction, and the flange portion 22 is formed at the end of the extension pipe 20.

The bypass pipe 30 is made of a PE material.

As shown in FIG. 2, the bypass pipe 30 is formed by connecting a plurality of PE pipes 31 to each other by heat fusion using a heat welding machine, and a flange member 32 are thermally welded and connected.

At this time, the length of the bypass pipe (30) is adjusted to fit the distance of the extension pipe (20).

The opening and closing valve 50 connects the extension pipe 20 to the connection part 12 and closes the main valve to temporarily keep the flow of tap water flowing through the water pipe 10, 12).

At this time, the open / close valve 50 uses a sandwich valve which is mainly used in the construction of the sub-means method.

As shown in FIG. 3, the fixing table 40 is formed by bending a strip of a metal material having a high strength. The middle portion is configured to surround the upper circumferential portion of the bypass tube 30, An elongated fixing portion 41 is formed and fixed to the paper 1 by an anchor bolt 42 passing through the fixing portion 41. [

At this time, the fixing table 40 is composed of a plurality of fixtures 40, and is connected to the bypass pipe 30 at a predetermined interval, so that the pressure of the tap water flowing through the bypass pipe 30 or the water hammer, (30) is prevented from flowing.

Therefore, after the extension pipe 20 is connected to the connection part 12 within the work hole 2 and both ends of the bypass pipe 30 are connected to the extension pipe 20, Closing valve 50 is provided in the connection portion 12 and the bypass valve 50 is closed and the bypass valve 50 is closed by using the bypass valve 50. [ The tap water supplied through the water supply pipe 10 bypasses the rehabilitation unit 11 when the water supply pipe 21 is opened.

According to the construction of the bypass tube of the water supply pipe constructed as described above, the connection portion 12 is provided so as to extend upward in the interior of the work implement 2, the lower end portion thereof is connected to the connection portion 12, A pair of extension tubes 20 extending to an upper portion of the sphere 2 and having a bypass valve 21 at an intermediate portion thereof and a pair of extension pipes 20 extending along the paper 1, And the tap water supplied through the connecting portion 12 bypasses the regeneration unit 11. [

Therefore, unlike the conventional method in which the ground 1 is to be excavated in order to bypass tap water through the water supply pipe 10, tap water is bypassed to the rehabilitation unit 11 without digging the ground surface 1 So that it is easy to work and can shorten the working time.

The extension pipe 20 is made of a metal material having a high strength and is connected to the circumferential surface of the connection part 12 by a bottom end hydraulic method. The bypass pipe 30, unlike the extension pipe 20, The intermediate portion of the bypass pipe 30 can be appropriately bent along the curvature of the road, and the construction of the bypass pipe 30 is advantageously facilitated.

Particularly, the bypass pipe 30 is constructed by connecting a plurality of PE pipes 31 by heat fusion using a heat welding machine and connecting flanges 32 at both ends thereof by thermally welding them. It is possible to freely adjust or extend the length of the body 30.

The bypass pipe 30 is provided with a fixing table 40 which is provided to surround the periphery of the bypass pipe 30 and is fixed to the paper surface 1 and fixes the bypass pipe 30 to the paper surface 1 This is advantageous in that the bypass pipe 30 can be prevented from flowing due to the pressure of tap water passing through the bypass pipe 30 or the water hammer generated when tap water flows.

That is, when the high-pressure tap water is supplied through the bypass pipe 30, the bypass pipe 30 is made of a resilient PE material. When the tap water is supplied through the bypass pipe 30, The bypass pipe 30 may collide with another object on the main surface or the like and be damaged.

According to the present invention, however, since the middle portion of the bypass pipe 30 is fixed to the ground 1 by the fixing table 40, the pressure of the tap water or the water hammer generated by the tap water flows into the bypass pipe 30, There is an advantage that the middle portion can be prevented from flowing and being damaged.

A plurality of extension pipes 20 may be connected to the connection unit 12 so that a plurality of extension pipes 20 and bypass pipes 20 may be connected to the connection pipe 12. In this case, It is also possible that the tap water is bypassed through the drain pipe 30.

4 and 5 illustrate another embodiment according to the present invention in which the fixing table 40 includes a lower support 43 fixed to the paper 1 and a lower support 43 fixed to the periphery of the bypass tube 30 And a shock absorber 45 connected to the stationary ring body 44 to attenuate the lateral vibration of the stationary ring body 44. The stationary ring body 44 is fixed to the stationary ring body 44, .

The lower support 43 is configured to extend laterally and is fixed to the floor by an anchor bolt 42 and a guide rail 43a extending laterally is provided on the upper surface.

The fixing ring body 44 is slidably coupled to the guide rail 43a in the lateral direction and has a lower ring body 44a formed with an insertion groove 44b through which the bypass pipe 30 is inserted, And an upper ring member 44c coupled to an upper portion of the ring member 44a and pressing the upper surface of the bypass pipe 30 inserted into the insertion groove 44b to fix the bypass pipe 30. [

At this time, the upper ring body 44c is fixed to the lower ring body 44a by the fixing bolt 44d.

The shock absorber 45 has a cylinder-shaped shock absorber 45 whose one end is fixed to the lower support 43 and whose other end is connected to the fixed ring body 44.

5, the shock absorber 45 generates a damping force when the fixed ring body 44 is slid laterally in the central portion of the lower support 43, So that the stationary ring body 44 is held at the center of the lower support 43.

According to the construction of the bypass tube of the water pipe constructed as described above, the fixing table 40 includes a lower support 43 fixed to the paper 1, and a lower support 43 fixed to the periphery of the bypass tube 30, And a shock absorber 45 connected to the stationary ring body 44 to attenuate the lateral vibration of the stationary ring body 44, The bypass pipe 30 coupled to the fixing ring body 44 is positioned at the center of the lower support 43 and the pressure of the tap water passing through the bypass pipe 30 or the water hammer The buffer 45 absorbs the flow of the bypass pipe 30 properly and the external force applied to the bypass pipe 30 is removed when the flow is generated in the bypass pipe 30. Accordingly, By allowing the tube 30 to bend to the bottom of the lower support 43, That the tube 30 is damaged there is a merit capable of preventing more effectively.

That is, since the fixing table 40 simply fixes the bypass pipe 30 to the paper surface 1, it is possible to prevent the impact pipe 30 from being damaged due to a change in the pressure of the brine water passing through the bypass pipe 30, The bypass pipe 30 can not receive the same and may be damaged.

However, in the case of the present invention, when an impact is applied to the bypass pipe 30 due to a change in the pressure of the brine water passing through the bypass pipe 30, the fixing table 40 is rotated such that the bypass pipe 30 is properly flown It is possible to prevent the bypass pipe 30 from being damaged.
