うにしていた。 This type of transport pipe cleaning device inserts a sponge ball and a cleaner piston into one end of the transport pipe to be cleaned, connects a pump to that end, and supplies high-pressure water to the transport pipe by driving the pump. The sponge ball and cleaner piston are force-fed from one end of the transport pipe to the other end, thereby pushing the ready-mixed concrete and earth and sand adhering to the inner wall of the transport pipe out of the transport pipe through the opening at the other end, thereby cleaning the inside of the transport pipe. was.

In the conventional transport pipe cleaning method as described above, after the fresh concrete and earth have been pushed out of the pipe, the sponge balls and cleaner pistons are pushed out of the pipe from the other end by high-pressure water and released. Therefore, the cleaning water inside the pipe also flows out of the pipe. In this case, if the piping is relatively long distance, there will be a considerable amount of residual washing water in the transport pipe, and if this overflows into a work site that does not have drainage or treatment equipment, it will cause problems on-site work. Even if there is a drainage facility, if it is regulated that cleaning water containing fresh concrete or earth and sand cannot be directly drained, there is a problem that the transport pipe cannot be cleaned immediately after the fresh concrete or earth and sand is pumped. It was hot.

Switch and connect both with fitting 1
Bonded by 0. After that, water recovery on-off valve 1
7 is closed, the water supply on-off valve 13 is opened, and the water supply pump 14 is started. As a result, when the cleaning water in the tank 16 flows into the stuffing accommodating part 2, the stuffing 3, which had been put into the accommodating part 2 from the large diameter side by removing the lid 2a in advance, is moved from the accommodating part connection port 6 by water pressure. It is sent into the transport pipe 12 through the valve body 9, and while pushing the remaining materials such as ready-mixed concrete and earth and sand inside the transport pipe 12, it is sequentially pushed out to the terminal end of the transport pipe 12, and is then released from the opening 19 to the outside of the transport pipe 12. discharge to. Then, when the stuffing 3 hits the terminal end surface 12a of the transport pipe 12 as shown in FIG.
The pressure on the discharge side of the water supply pump 14 increases, and this pressure is measured, for example, with a pressure gauge 25 connected to the discharge side of the water supply pump 14, and by visually confirming that the indication scale has exceeded the set value, the filling can be removed. 3 has reached the end of the transport pipe 12. If this is confirmed, the water supply pump 14 is stopped, the on-off valve 13 is closed, and the on-off valve 17 is opened. Thereafter, the opening 19 is closed with the lid member 20, the air venting on-off valve 24 is closed, and the air supply on-off valve 2 is closed.
2 and start the air compressor 23.
As a result, compressed air passes through the pipe 26 to the transport pipe 1.
2, the filling 3 becomes a piston and moves inside the transport pipe 12 toward the switching valve 4. At the same time, the cleaning water inside the transport pipe 12 is supplied to the valve body of the switching valve 4. 9 and stuffing storage section 2, on-off valve 1
7. Returned to tank 16 through piping 18 and recovered. At this time, since the residue in the transport pipe 12 is water, compressed air can also sufficiently push the stuffing 3 back in the opposite direction.
そして、タンク１６への戻り洗浄水がなくなれ
ば、詰め物３は自動的に収容部２内に戻り、回収
されることになる。 When there is no more washing water to return to the tank 16, the stuffing 3 automatically returns to the storage section 2 and is recovered.
上記詰め物３及び洗浄水の回収が終了したなら

易になり、洗浄作業も簡便になる。 In this embodiment as described above, the transport pipe 12
When cleaning, the switching valve 4 is switched and connected to the stuffing container 2 side, and high-pressure cleaning water is fed from the water supply pump 14 through the stuffing container 2, thereby sending the stuffing 3 together with the washing water into the transport pipe 12. ,
Open the opening 1 to remove residual materials such as fresh concrete and earth and sand inside the pipe.
9 to the outside, and when the discharge of the residue inside the pipe is completed, the opening 19 is closed with the lid member 20 and compressed air is sent into the pipe from the air compressor 23, thereby flushing the cleaning water into the tank. 16 and the stuffing 3 to the storage section 2 automatically, it can be used in places where there are restrictions on disposal of washing water, or in places where there are restrictions on disposal of washing water, or where there are restrictions on the disposal of washing water.
The inside of the pipe can be easily cleaned even at the installation site in step 2, and since the cleaning water is collected into the tank 16, the post-treatment of the cleaning water is easy and prevents the work site from being contaminated by the cleaning water. In addition to not interfering with on-site work, the stuffing material 3 for removing residue inside the pipe is automatically collected into the designated storage section 2 when cleaning water is collected, and is automatically stored inside the transport pipe 12 when cleaning the inside of the pipe. As long as the stuffing 3 is not damaged and becomes unusable, it can be used repeatedly, and there is no need for manpower to insert and take out the stuffing 3 into the transport pipe 12, making it easy to manage the stuffing 3. Cleaning work also becomes easier.
