に関するものである。[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention is a method for collecting surface water from river streams for relatively large amounts of water for agricultural, industrial, or snow-melting purposes. This article relates to a dust removal/filtration water intake device with a new structure for the purpose of

堤を考えると莫大な建設費を必要とする。(Prior art) Conventionally, in order to take in a relatively large amount of surface water from a river, the river is dammed up with a movable or fixed weir, the flow velocity is lowered, and gravel is precipitated.・The general rule was to install a water intake door just downstream of the stream, and install a settling basin and dust removal equipment within the embankment to allow the water to flow naturally. However, this method requires a huge amount of construction cost considering the construction of the weir and the associated embankment as it involves raising a weir across the river.

る。 In addition, in slow-flowing rivers where the water was deep, a water intake tower was installed, a water intake door was installed inside the tower, and a river water conduit was buried, and a settling pond inside the embankment was used to take in water either by gravity or by pump-up. Furthermore, traditional construction methods include water intake using water intake frames, but today there are few construction methods that are suitable from a flood control perspective for areas with embankments and important rivers.

河川表流水取水装置として取水量毎分20m3を超
えるろ過取水装置は一般に中規模以上の装置とな
つている。 As river surface water intake devices, filtration water intake devices with an intake capacity of more than 20 m 3 per minute are generally medium-sized or larger devices.

河川の流水には通常芥や砂が浮遊しており、ま
は降雨により洪水となればこれら異物の量が増加
する。従つて取水量が多くなればこれらの芥や砂
の量が比例して増加するため河川表流水取水の大
きな問題となり、これら多量の芥や砂の除塵やろ
過をすることが重要な事項となる。(Problems to be Solved by the Invention) Mold and sand are usually suspended in running water of rivers, and when a flood occurs due to rain, the amount of these foreign substances increases. Therefore, as the amount of water intake increases, the amount of these sludge and sand increases proportionally, which becomes a major problem in river surface water intake, and it is important to remove dust and filter this large amount of sludge and sand. .

きる様な改良が要望されており、さらに河川の治
水面から洪水時においても取水構造物が損傷した

いもの等が要望されている。 In addition, there is a need for improvements that will allow large amounts of water to be taken in from shallow water depths during dry periods, and improvements that will prevent the intake structure from being damaged or cause levee breaches even during floods from the perspective of river flood control, as well as management and operation aspects. There is a demand for something that is easy to install, maintain and inspect, and that does not require advanced technology.
そこでこの発明はこれら上記の問題点を解決
し、平常水位の際は勿論、増水時のおいても低水

提供するものである。 Therefore, this invention solves the above-mentioned problems and creates a new river system that removes dirt and sand by filtering out dust and sand not only during normal water levels, but also during high water levels and low water levels, making it possible to take in a large amount of water stably. The present invention provides a dust removal filtration device for surface water.

A streamlined water intake structure body 1 is constructed to protrude from the river bed, and a total of six water intake ports 2 (three on each side) are opened at the upper part of both sides, and a large number of vortex plates 3 are installed on the outside of each of these intake ports 2. vertically, and a V-shaped slotted wire screen 4 is stretched inside and a combined water intake frame 5 is fixedly installed,
In addition, five manholes 6 are provided in the upper part, and an inspection port 7 leading to the interior is installed vertically in the front and rear parts, and three water absorption tanks 8 are provided in the upper part of the inside of the water intake port 2, and one sediment tank is provided in the lower part. A joint well 9 is formed, and a connecting pipe 10 having a butterfly valve 11 is installed vertically from each water absorption tank 8 to the sand settling well 9, and a siphon tube 12 is installed on the upper part of the connecting pipe 10. A sand pump 13 for discharging accumulated sediment is installed at one corner of the well 9, and a river water conduit 14 is buried from one corner wall to connect to the Punpu well P (not shown). In the drawings, reference numeral 15 denotes a supply/exhaust pipe connecting the water absorption tank 8 and the sand settling well 9.

る。(Function) To explain the function of the water intake device of the present invention configured as described above, the main body 1 of the water intake structure has a semi-conical shape at the upstream and downstream sides and a streamlined shape as a whole to reduce the resistance of flowing water and minimize the resistance to the river area. It has the shape of a limit. The lower sand joint well 9 has sufficient penetration as a riverbed structure, and the entire structure is stable from a flood control perspective.

る。 The flowing water collides with the water intake structure main body 1 and causes a scour action similar to the bridge piers, so the entire surrounding area is stabilized by the bed protection work G. The eddy current plate 3 installed at the water intake 2 is installed in a direction perpendicular to the flowing water, so it protects the V-shaped slot wire screen from boulders, driftwood, etc., and prevents the adsorption of waste by the upward eddy current, making it tilted. Therefore, it has the effect of gradually floating to the upper layer.

て河床へ放出する。 The size of the water intake port 2 is determined depending on the amount of water intake, and it is installed at a plurality of locations to enable a large amount of water intake and dust removal filtration. The water absorption tank 8 has an airtight manhole 6 at the top.
It has an airtight structure. Connecting pipes 10 of an appropriate diameter are installed vertically from each water absorption tank 8 to the lower sand settling well 9, and a butterfly valve 11 is provided inside the upper part of the connecting pipe 10. The butterfly valve 11 is opened and closed by opening the valve operating port M and operating it with an opening/closing rod. In addition, the siphon pipe 12 above the connecting pipe 10 allows overflow from the water intake to flow in without disturbing the river water level, thereby preventing the intrusion of earth and sand.
The flow rate of the flowing water that has reached the sand settling well 9 decreases depending on the volume, and the sand and gravel with high specific gravity settle and accumulate in the lower right direction of the drawing, so that the sand pump 13 is occasionally operated to discharge it to the river bed.
沈砂接合井９の一隅には河川導水管１４を埋設
し堤内のプンプ井Ｐへ自然導水するものである。 A river water conduit pipe 14 is buried in one corner of the sand joint well 9 to naturally lead water to the Punpu well P within the embankment.

自然取水が可能である。なお給排気管１５は沈砂
接合井９上部の空気抜きのためのものである。 When the pump stops, the water level in the pump well rises and the inflow stops, allowing natural water intake without the need for any water management operations. Note that the supply and exhaust pipe 15 is for venting air from the upper part of the sand settling well 9.

発揮する有効な取水装置である。(Effects of the Invention) As described above, the present invention has minimal water resistance due to its minimal size and streamlined shape relative to the river area, and is sufficiently embedded as a water intake structure, so it is extremely effective in terms of flood control. It's safe. Also, there is a swirl plate and V at the water intake.
quicksand, combined with slotted wire screen
In addition to protecting against waste, the eddy current reduces adsorption of waste and has a separating effect, allowing for clear water intake. Even when the river water level fluctuates, the action of the siphon pipe prevents air from being entrained, and the overflow suction by the connecting pipe reduces the inflow of earth and sand, and since it is a natural water intake structure with no operating mechanism, daily management is easy. It is an effective water intake device that exhibits many effects, such as being economical and ideal for taking in large amounts of river surface water in medium-sized or larger rivers.
