りと共に機械はまずます高価になる。Conventionally, when fresh concrete is pumped using a concrete pump, it is well known that as the mix of fresh concrete becomes harder, it becomes difficult to pass through the pipe, eventually causing blockage. This phenomenon occurs most often in constricted pipes, followed by bent pipes,
Straight pipes and their frequency will be less. This occurs because cement, sand, and gravel separate inside the pipe as the ready-mixed concrete changes shape during pumping, increasing friction with the pumping pipe and exceeding the discharge pressure of the pump. Once a blockage occurs, the pressure feeding is stopped, the blockage is found first, the pipes before and after the blockage are removed, and all the ready-mixed concrete inside the pipes is removed.
After that, the pipes are connected again and pressure feeding is resumed. It is not easy even for experienced and skilled workers to discover the blocked part of ready-mixed concrete, which is completely invisible from the outside. Work continues to remove the blockage and restore it to its pre-occlusion condition. As this process continues, the ready-mixed concrete in other pipes begins to harden. Sometimes, the raw comb vibrator is disposed of. The physical exhaustion of workers and economic losses (compensation for ready-mixed concrete and damage to machinery) are a source of frustration for those engaged in this work. In order to overcome this drawback, the concrete pump driving horsepower has to be increased, and as the pumping and pressure increases, the machine becomes more expensive.
又、コンクリートポンプの圧送能力の増大は従前前えら
れなかった。貧配合の生コンでも圧送5r能となった反
面、現場での作業はまずます長距離高所大量打設の要求
が強くなり、一度、閉塞してつまづくと大きな経済的損
失となってはねかえる。Furthermore, the increase in the pumping capacity of concrete pumps was previously unachievable. Although it has become possible to pump 5R of ready-mixed concrete with a poor mix, on-site work is increasingly demanding long-distance, high-volume casting in high places, and once a blockage occurs, there is a huge economic loss. change.
以上の欠点をある程度緩和する目的で発明されたのが本
発明の振動装置つき圧送パイプである。The pressure feeding pipe with a vibrating device of the present invention was invented to alleviate the above-mentioned drawbacks to some extent.

うまでもない。当然圧送能力の大幅な向上が期待できる
。It is well known that in the case of a mild blockage, the blockage can be cleared by hitting the area where the blockage is thought to be with a hammer, applying vibration, and then repeatedly rotating the concrete in forward and reverse directions to shake it back and forth. Taking this as a hint, this device uses a vibrating device to continuously perform this tapping action to change the ready-mixed concrete in the pipe so that it is less likely to become clogged. Continuous micro-vibrations cause the cement paste in the ready-mixed concrete to seep into the area where the pipe's inner wall and the ready-mixed concrete come into contact, greatly reducing friction. Particularly in the case of throttle pipes, rapid changes in cross-sectional area cause separation within the ready-mixed concrete, causing blockages, but by connecting this device, blockages can be greatly reduced. In addition, since the vibrations are transmitted to the front and back of the vibrating device, it goes without saying that blockage in the constricted pipe or bent pipe can be avoided. Naturally, a significant improvement in pumping capacity can be expected.

′#f許出願人 松田敏雄This invention is not a problem when you compare the cost of increasing the size of the engine, motor, oil pump, and other equipment required to check the discharge pressure of the concrete pump to 10 kg/C4 in order to prevent blockage of fresh concrete pumping. Easy to do. In addition, by simply connecting this device to the pressure feed pipe of a conventional concrete pump, you can create a new, stronger machine. People Toshio Matsuda
