다음에 본 발명의 콘크리트펌프의 잔류콘크리트처리방법을 적용하는 콘크리트펌프를 제1도에 의해 설명하면, (1)이 호퍼, (2)가 게이트밸브, (3)이 콘크리트수송관, (4)가 모래, 자갈, (6)이 시멘트페이스트를 포함한 물, (7)이 호퍼(1)내의 시멘트페이스트를 포함한 물(6)을 흡인하는 소형경량의 수중펌프, (8)이 호스, (11)이 스폰지, (12)가 콘크리트실린더이다.Next, a concrete pump to which the residual concrete treatment method of the concrete pump of the present invention is applied will be described with reference to FIG. 1, where (1) is a hopper, (2) is a gate valve, (3) is a concrete transport pipe, and (4) Small sand, gravel, (6) water containing cement paste, (7) a small lightweight submersible pump that sucks water (6) including cement paste in the hopper (1), (8) hoses, (11) This sponge 12 is a concrete cylinder.
콘크리트압송종료후의 호퍼(1)내 및 콘크리트수송관(3)내에 잔류하는 잔류콘크리트를 배출할 때에는, 콘크리트펌프를 공운전해서 그때 발생하는 공기압에 의해, 호퍼(1)내 및 콘크리트수송관(3)내에 잔류하는 잔류콘크리트의 일부를 콘크리트수송관(3)의 선단부로부터 배출한다.When discharging the residual concrete remaining in the hopper 1 and the concrete transport pipe 3 after the completion of the concrete transport, the concrete pump is operated by air and the air pressure generated at that time is used to discharge the concrete in the hopper 1 and the concrete transport pipe 3. Part of the remaining concrete remaining in the c) is discharged from the distal end of the concrete transport pipe (3).
이어서 호퍼(1)내의 잔류콘크리트를 긁어 모으고, 콘크리트펌프를 저속운전해서 호퍼(1)내의 잔류콘크리트를 콘크리트실린더(12)내에 한계까지 흡입한다.Subsequently, the residual concrete in the hopper 1 is scraped, the concrete pump is operated at low speed, and the residual concrete in the hopper 1 is sucked to the limit in the concrete cylinder 12.

When the water is short, the operation of the concrete pump is continued and the sponge 11 is pushed by the air pressure generated at that time, and the residual concrete is discharged from the distal end of the concrete transport pipe 3.
그리고, 잔류콘크리트의 배출이 종료하면, 콘크리트펌프를 역전시켜 콘크리트수송관(3)내의 물을 호퍼(1)에 복귀시킨다. 이 복구시킨 물에 의해, 호퍼(1)내에 잔류하고 있는 잔류콘크리트를 모래·자갈(4)과 시멘트페이스트를 포함한 물(6)로 분리한다. 시멘트페이스트를 포함한 물(6)은, 소형경량의 수중펌프(7)→호스(8)를 거쳐 강제적으로 레미콘차에 복귀시키거나, 배수홈을 거쳐 오수처리장치에 배출한다.When the discharge of the residual concrete is finished, the concrete pump is reversed to return the water in the concrete transport pipe 3 to the hopper 1. By this recovered water, the remaining concrete remaining in the hopper 1 is separated into sand, gravel 4 and water 6 including cement paste. The water 6 including the cement paste is forcibly returned to the ready-mixed vehicle via the small-sized submersible pump 7 → the hose 8 or discharged to the sewage treatment apparatus via the drain groove.
또, 호퍼(1)내에 남은 모래와 자갈을 그대로 방치해 두어서 다음번 다져넣기할 때, 호퍼(1)내에 투입한 시멘트페이스트 또는 모르타르와 혼합시키고, 압송해서 자원으로서 유효 이용한다.In addition, when the sand and gravel remaining in the hopper 1 are left as it is to be chopped next time, it is mixed with the cement paste or mortar put into the hopper 1, and transported to effectively use it as a resource.

When the discharge of the residual concrete is finished, the water in the concrete transport pipe is returned to the hopper, and the water including the cement paste in the hopper is forcibly discharged to the ready-mixed car or the drainage groove, and the sand and gravel remaining in the hopper are left as it is. Then, when the next chopped, mixed with cement paste or mortar put into the hopper and conveyed. Therefore, it is not necessary to open the Y-shaped tube or the gate housing as described above, and to discharge the residual concrete, thus simplifying the operator's work. ② Moreover, we do not pollute the ground near the site and can use resources effectively.
