る。2. Description of the Related Art As shown in FIG. 3, an in-pipe water extracting device C for extracting water W stored in an existing pipe A such as a pipe buried underground is provided with a camera 1 for in-pipe photographing, Illumination lamp for illuminating the shooting location, and suction unit 3 for sucking water W in the pipe
Is provided on the distal end side of a water extraction hose 5 having flexibility. Then, the water extraction head 4 is inserted into the existing pipe A, and the inside of the pipe A is observed from the ground based on a photographed image of the camera 1 transmitted to the monitor 7 on the ground via the camera cable 6. While moving inside, the water W accumulated in the pipe A is searched, the suction part 3 is inserted into the water W, and the water W is driven by the pump P attached to the rear end side of the extraction hose 5. Thereby, it is configured to be able to be discharged out of the pipe A through the water extraction hose 5. Therefore, when the water extraction head 4 is inserted into the pipe A, the water extraction hose 5 is also drawn into the pipe A together with the water extraction head 4. However, it is difficult to predict where the accumulated water is located, and it is also difficult to completely understand the arrangement of the existing pipes. It is difficult to completely determine in advance whether or not it is necessary to be inserted into the inside. For this reason, conventionally, the water extraction hose 5 is provided with one kind of sufficient water so that the water extraction head 4 can be inserted deep inside the existing pipe A and the water W accumulated in the pipe A can be discharged out of the pipe A through the water extraction hose 5. The length is set to a certain length, and the water W can be discharged from the rear end side by driving the pump P.

ることを目的とする。However, according to the above-mentioned in-pipe water extraction device, if the place where water is to be extracted is a relatively short distance from the insertion position of the water extraction head, the water extraction hose must have a sufficient length and constant length. Since the length is set to be long, there is a problem that an unnecessarily long water extraction hose hinders the work and the workability is poor. In addition, even when the length of the water extraction hose inserted into the pipe is relatively short, the water remaining in the pipe is driven by the pump to drive the water extraction hose of a fixed length, despite the insertion part into the pipe being short. Since it is necessary to pass from the front end to the rear end, there is a problem that the pressure loss is large and it is difficult to improve the water extraction efficiency. Therefore, the present invention has been made in view of the above-described circumstances, and is capable of responding to a place where water should be extracted, with good workability, and an in-pipe water extraction device capable of performing water extraction with high water extraction efficiency. The purpose is to provide.

A configuration in which the inside of the tube is observed from outside the tube based on the transmitted photographed image, the water W in the tube is sucked by the suction unit 3, and the water W in the sucked tube is discharged to the outside of the tube through the water extraction hose 5. In the in-pipe water extraction device C, the water extraction hose 5 is constituted by a plurality of divided water extraction hoses 8 connected in a longitudinal direction thereof, and the plurality of adjacent water extraction hoses 8 are detachably connected to each other. A hose connection portion 9 for communication is provided in each of the divided water extraction hoses 8. [Operation] The water extraction hose is constituted by a plurality of divided water extraction hoses connected in the longitudinal direction thereof, and each of the divided water extraction hoses is connected to a plurality of adjacent water extraction hoses in a detachable manner. Since the portion is provided, the required length of the whole water extraction hose can be adjusted by connecting and connecting the required number of divided water extraction hoses to be connected and connected. [Effect] Therefore, it is possible to respond by adjusting the length of the water extraction hose according to the place where water is to be extracted, and the work efficiency is improved because the water extraction hose does not become unnecessarily long so as not to hinder the work. Can be done. Further, when the place where water is to be drawn is a relatively short distance from the insertion position of the water drawing head, the number of connected divided water drawing hoses is reduced, the length of the water drawing hose is shortened, and the pump is driven to drive water. Draining from the back end of the extraction hose,
Pressure loss can be reduced. That is, since the water extraction ability can be improved, water extraction can be performed with high water extraction efficiency. In addition, even if the location where water should be drawn is farther than expected from the insertion position of the water extraction head, increase the number of divided water extraction hoses to be connected, extend the length of the water extraction hose, and observe the inside of the tube with a camera. Continuing, the in-pipe water extraction operation can be performed.
