Therefore, it is preferable that the separation distance between the end of the drain pipe 363 and the end face of the striking plate 362 is 30 to 70%.

At this time, the inner circumferential surface of the drain pipe 363 may form irregularities, and the irregularities may be utilized as a means of lowering the flow rate of the discharged water.

In addition, the discharge water passing through the drain pipe 363 comes into contact with the striking plate 362 to relieve the water pressure and flow rate of the discharge water, and the discharge water with the water pressure and flow rate relieved in this way is naturally drained through the through hole 364 and remains. It reduces the water discharge pressure and flow rate, and at the same time, naturally drains the residual water (without water pressure and flow rate) to prevent sinkholes in the soil around the immobilization structure, and to keep the area around the water supply clean by preventing the residual water from being sprayed in all directions. has the effect of
