Description

Be discharged through a discharge pipe provided on the rising water passage portion siphon tube end, to ensure the sealing of the tube end, certainly it obtained the siphon effect is, of course, exhaust water passing through the start To reduce the time, maintain the stability of the discharge end when the water intake status of the intake port changes, and deposit sediments such as when opening the siphon tube end into the reservoir and installing a check valve at the discharge port There is no clogging or catching of foreign matter like tree branches.

In the figure, (c) is a view of the outer wall surface of the fifth embodiment dam framing, and (d) is a view of the dam laying inner device. It is detail drawing of the discharge pipe 13 of 5th Example. (E) in the figure is an AA view of FIG. 11, and (f) is a BB sectional view. (G) in the figure is a detailed cross-sectional view around the water inlet h common to FIGS. 1, 3, 5, and 7, and (H) is a detailed cross-sectional view around the water inlet h in FIG. is there.

In addition, since the deposit j accumulated for a long period of time is difficult to be sucked, a nozzle directed downward or forward is disposed at the lower end of the auxiliary water suction pipe 4D, and separately prepared pressure water is flushed.
Further, the method of flushing the pressure water can be adopted as needed in the case of other embodiments, but usually, the sediment near the dam lake dam is light and fine and does not need to be provided.

Claims (6)

In dam lakes and ponds, the pumping pipe was extended downward along the wall of the levee body , the lower end water intake was opened near the sediment or the bottom of the lake, and the upper end was provided by constricting the upper part of the dam body. and passed under the discharge gate of the spillway is opened, Rutotomoni is on該揚water tube provided per Sokoto of discharge gate, in the lower end, the complement of the predetermined length is opened complement water inlet at the upper end In the case of a rectangular pump, the water suction pipe is placed on top of the upper side of the water pump, and the upper side wall of the lower end of the auxiliary water pipe is shaped like a bowl and protrudes from the water inlet of the water pump. Open the water inlet, and in the case of a circular pumping pipe, the lower end of the auxiliary water intake pipe provided along the water pumping pipe is surrounded by the outer periphery of the water inlet of the pumping pipe so that it protrudes somewhat from the water inlet. Connect and communicate with a water inlet opened in the guard, so that the upper water is injected into the water inlet of the pumping pipe. Apparatus to eliminate with effluent precipitate dam lake. The upper end of the pumping pipe is extended, the outer wall surface of the dam lake dam body is extended downward, and the siphon pipe part provided with the rising pipe part at the terminal end part is provided. A device that removes sediment with discharged water. Inside the dam lake of the dike channel with the gate provided at the middle height of the dam body, the pumping pipe is connected and extended downward, and the lower end water intake is sedimented or near the dam lake bottom is opened to Rutotomoni, in the lower end of該揚water pipe, an auxiliary water suction pipe of a certain length is opened complement water inlet at the upper end, in the rectangular lifting pipe, in a manner superposed on the upper side of the riser pipe The water inlet is opened with the upper side wall of the lower end of the auxiliary water intake pipe projecting from the water intake of the pumping pipe in a bowl shape. The lower end of the supplementary water intake pipe is connected to and communicated with a water inlet opening in a guard provided so as to surround the outer periphery of the water inlet of the water pump pipe and protrude somewhat from the water inlet, A device that removes sediment from the dam lake along with the discharged water. The dam lake sediment according to any one of claims 1, 2, and 3 , wherein the lower part or the whole of the pumping pipe is configured to be slidable so as to raise and lower the water intake. Equipment to be removed with water. Connect and branch the intake pipe to the top of the pumped pipe to which the siphon pipe is connected, and once the intake pipe is raised upward, it is turned downward to ensure a height higher than the siphon head required by the equipment. The apparatus which removes the sediment of the dam lake of Claim 2 with discharge water which was opened in the dam lake of the water level which wants to stop pumping. At the end of the pipe that pumps and drains using siphon pipes and the pipe over the mountain of the pump (middle and high pipes), the pipe that discharges downwards is provided with an upward pipe at the end of the pipe the reservoir with a freely water in the tube body between portions of dissipating flow tube end is provided, punched on the bottom tube upper edge of the upward turning part, or a slit-shaped hole opens toward the downstream riser section An outlet device for siphon piping that is constricted and communicates between the reservoir and the pipe.
