It consists of and, remove the plug and connect the pull-in pipe to the socket.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a temporary pipe for a water pipe used when laying a sewer pipe.

[0002]

[Prior art]

 When laying the sewer pipe, the water pipe buried near the place where the sewer pipe is buried will be an obstacle, so it is necessary to remove the water pipe in the construction section.

In this case, since water supply to each home stops, a temporary pipe (connected to the water supply pipe) is provided in the removed section, and a water supply pipe is connected to this home for connection to the home. .

In the conventional method of connecting the lead-in pipe to the temporary pipe, as shown in FIGS. 3 and 4, a branch joint 2 is attached to the outer periphery of the connection portion of the temporary pipe 1.

The branch joint 2 described above has a pair of halves 4 and 4 which are formed into a cylindrical shape by stacking the facing surfaces of the projecting portions 3 at both ends, and a transparent body where the projecting portions 3 to be stacked are matched. A fastener 6 formed of a bolt and a nut that is inserted into the hole 5, a connection port 7 that protrudes continuously from the front surface of one half-split body 4 and penetrates the rear surface of the half-split body 4, and a half-split body. 4 is composed of an endless packing 8 arranged outside the inflow opening of the connection port 7 on the back surface of 4, and both the half halves 4 and 4 are circumscribed on the outer peripheral surface of the temporary pipe 1, and the overlapping protruding portions are formed. The branch joint 2 is attached while tightening the tightening tool 6 inserted through the through hole 5 in FIG.

Next, a hole is drilled in the temporary pipe 1 while inserting the drill of the punch into the connection port 7. After that, the lead-in pipe is screwed into the connection port 7 to be connected.

The leakage of water from the temporary pipe 1 toward the connection port 7 is prevented by the packing 8 which is compressed when the half-split bodies 4 and 4 are attached.

[0008]

[Problems to be solved by the device]

 If the above method is adopted, the number of branch joints used and the number of branch joints used will increase and the cost will increase significantly.

[0009] Furthermore, if the screw thread of the fastener is crushed during construction, there is a problem that it cannot be removed.

Furthermore, if the packing is damaged during handling, it needs to be replaced.

Therefore, an object of the present invention is to provide a temporary pipe that does not require a branch joint.

[0012]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a tubular body having a predetermined length, a socket provided so as to communicate with the tubular body at a predetermined space position on the surface between both ends of the tubular body, and each of these sockets. A structure consisting of a plug screwed into a socket is used.

[0013]

[Action]

 With the above-mentioned structure, the opposite ends of the pipes are laid by connecting the pipes with appropriate means so as not to hinder the operation of burying the sewer pipes in the removed area of the water pipes, and the ends of the pipes on both ends are raised. Connect to a water pipe.

Further, the lead-in pipe of each home is connected by removing the plug and screwing it into the socket.

[0015]

【Example】

 An embodiment of a temporary pipe according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, reference numeral 21 denotes a tubular body having a predetermined length, and a socket 22 communicating with the inside of the tubular body 21 is provided at a required space position on the surface between both ends of the tubular body 21. It is provided.

In the illustrated case, the socket 22 is provided with through holes 23 in the steel pipe tube body 21 at predetermined intervals, and the socket 22 is provided on the surface of the tube body 21 so as to be located outside the entire circumference of the through hole 23. The terminal was welded to prevent water leakage, but there is also a case where a socket is integrally provided on the pipe body by casting.

A plug 24 is screwed into each socket 22.

The number of sockets 22 with respect to the tubular body 21 is set freely.

With the above configuration, the opposing ends of the pipe body 21 are connected to each other through, for example, a commercially available joint (not shown) so as to have the same length as the removed length of the water supply pipe to form a temporary pipe.

Further, both ends of the temporary pipe body 21 connected as described above are connected (via joints) to the cut end of the water supply pipe remaining in the ground.

Furthermore, the lead-in pipe of each home is screwed into the socket 22 from which the plug 24 has been removed for connection.

[0023]

【effect】

 Since the temporary pipe according to the present invention is configured as described above, it is a labor-intensive work to make a hole in the temporary pipe by using a perforating tool and then install the branch joint for connecting the lead-in pipe. It is not necessary and has the effect of shortening the period for burying sewer pipes.
