豪雨や土石流に依るダムへの流入土砂や、湖沼の泥土、河川における土砂の採取や除去、産業施設水槽での泥土等、実に多くの種類の水中沈殿物の回収や除去が必要とされており、これ等沈殿物の除去には実に多くの種類の装置が提供されている。
本願発明人においても、広い範囲の揚砂揚泥を可能にする特許第３８９５５０５号を取得し、特願第２０１５−１１６０７８号を出願しているが満足できるものではなく、これを改善する。
There is a need to collect and remove many types of underwater sediments, such as inflows into dams caused by heavy rains and debris flows, mud from lakes and marshes, collection and removal of sediments from rivers, and mud from industrial tanks. Many kinds of apparatuses are provided for removing these precipitates.
The inventor of the present application has also obtained Japanese Patent No. 3895505 which enables a wide range of sanding mud and has applied for Japanese Patent Application No. 2015-1116078. However, this is not satisfactory and will be improved.
本願発明人の特許第３８９５５０５号及び特願２０１５−１１６０７８号の覆水路の思想を用いた揚泥装置の基本形態は、吸入管の上流端吸水口を沈殿物に埋没させない高さに維持する補吸水筒部を備え、該吸入管の下流沈殿物に埋没する途中位置には、管路底又は側壁に沿って窄穴配列した孔やスリット状に開窄した吸砂口を開口させた集砂管部分を備えて、下流基端部に送泥管を接続して落差やサイフォン、動力ポンプ、ジェットポンプ、エアーリフトポンプ、真空装置等の揚水源に接続し、管路内に必要な流速を与えて、集砂管部分が埋没した状態で沈殿物を回収又は除去する装置であり、これを「覆水路揚泥装置」と称呼して以下説明する。 The basic form of the mud apparatus using the idea of the cover channel of the patent No. 3895505 and the Japanese Patent Application No. 2015-116078 of the present inventor is a supplement that maintains the upstream end suction port of the suction pipe at a height that is not buried in the sediment. A sand collecting unit provided with a water absorbing cylinder part and having a hole arranged in a narrow hole along the pipe bottom or side wall or a sand absorbing port opened in a slit shape at an intermediate position buried in the downstream sediment of the suction pipe It is equipped with a pipe section, and a mud pipe is connected to the downstream base end and connected to a pumping source such as a head, a siphon, a power pump, a jet pump, an air lift pump, a vacuum device, etc. This is a device that collects or removes the sediment in a state where the sand collecting pipe portion is buried, and this will be referred to as a “floating channel mud device” and will be described below.
前記する覆水路揚泥装置の構成は基本構成であり、補吸水筒部分を省略し、集砂管部を直接沈澱物上に突出させることや、補吸水筒部に前記集砂管部同様の吸砂口を備えたもの備えないものがある。 The structure of the above-described drainage channel mud apparatus is a basic structure, omitting the auxiliary water absorption cylinder part, and projecting the sand collection pipe part directly on the sediment, or the same as the sand collection pipe part in the auxiliary water absorption cylinder part. Some are equipped with sand suction ports.
覆水路揚泥装置には、揚送濃度を安定した高濃度となしがたいことと、広い範囲の沈澱物を吸入させるために、集砂管の長い範囲に吸砂口を開窄して吸入させると、揚水源で吸引される下流側が最も強く吸引されるために、該下流側吸砂口の周辺沈殿物が優先して吸入排除され、該上方がすり鉢状に開放（以降“吸い破り現象”と称呼する）されて、開放された該吸砂口の流入速度が一定速度以下になると該集砂管の上流側吸砂口からの吸砂はできなくなる大きな課題がある。 In the irrigation channel pumping device, it is difficult to achieve a high and stable pumping concentration, and in order to inhale a wide range of sediment, the sand suction port is opened in a long area of the sand collecting pipe for inhalation. Then, since the downstream side sucked by the pumping source is sucked most strongly, the sediment around the downstream sand suction port is preferentially sucked out and the upper part is opened in a mortar shape (hereinafter referred to as “sucking phenomenon”). If the inflow speed of the opened sand suction port becomes equal to or lower than a certain speed, sand suction from the upstream sand suction port of the sand collecting pipe cannot be performed.
吸い破り現象を避けるために、覆水路揚泥装置における集砂管部を極端に短縮した形態や、覆水路揚泥装置の集砂管部分を立設した形、或いは、吸砂口を設けた補吸水筒部分のみで揚砂するようにした形態の“縦形揚泥装置”とした場合にも、揚送濃度が低いことや、縦方向吸砂口となるために、休止中に管路内堆砂を生じやすく、稼働初期閉塞を生じやすい等の課題がある。 In order to avoid the suck-through phenomenon, the sand collecting pipe part in the drainage channel mud equipment is extremely shortened, the sand collecting pipe part of the drainage pipe mud equipment is erected, or the sand suction port is provided. Even in the case of a “vertical mud lifting device” in which the sand is pumped only with the auxiliary water suction cylinder, the pumping concentration is low, and because of the vertical sand suction port, There are problems such as easy sedimentation and initial blockage.
本発明では、吸い破り現象を克服する手段として、吸い破り現象を極力遅らせることと、吸い破り現象発生前に集砂管の上流側（補吸水筒側）沈殿物を吸入排除されやすくして解決する。 In the present invention, as a means of overcoming the suck-through phenomenon, the problem is solved by delaying the suck-up phenomenon as much as possible and making it easier for the sediment on the upstream side of the sand collection pipe (the auxiliary water absorption cylinder side) to be sucked out before the suck-through phenomenon occurs. To do.
吸い破り現象を遅らせる手段として、集砂管部の吸砂口開口高さ位置を下流基端側では、直下部又は低い高さ位置に開窄し、上流側では水路中心近くの高い位置になるように、階段状、或いは、傾斜させて開窄し、該集砂管の上流側で沈殿物が吸入されやすく、且つ、吸入沈殿物が水路内で混合排除されやすくする。 As a means of delaying the wicking phenomenon, the sand suction port opening height position of the sand collecting pipe portion is narrowed to a lower part or a lower height position at the downstream base end side, and at a higher position near the water channel center at the upstream side. In this way, it is narrowed stepwise or inclined so that the sediment is easily sucked upstream of the sand collecting pipe, and the sucked sediment is easily mixed and removed in the water channel.
覆水路揚泥装置の補吸水筒部や縦形揚泥装置のように、上下方向水路に吸砂口を開窄した管路にあっては、該管路内に水路方向仕切を設けて、吸砂口水路と非吸砂口水路に分割し、該非吸砂口水路では確実な上方水の流入水路を確保し、吸砂口水路では濃密な沈殿物を流入させ、該水路方向仕切の下方端で合流させ混合することで、稼働初期の通水を円滑にし、混合濃度の安定化を図る。 In the case of a pipeline with a sand suction port constricted in the vertical channel, such as a supplementary water suction cylinder section or a vertical type pump in the irrigation channel mud device, a water channel direction partition is provided in the pipeline. Divided into a sand mouth channel and a non-sand suction channel, the non-sand suction channel ensures a positive water inflow channel, a dense sediment flows into the sand port channel, and the lower end of the channel direction partition In order to stabilize the mixing concentration, smooth the water flow at the beginning of operation.
覆水路揚泥装置の集砂管部吸砂口の上流端には、該集砂管下半を大きく開窄した先端吸砂口を開口させ、外部沈殿物の流入を容易にする。 At the upstream end of the sand collecting pipe portion sand suction port of the water drainage mud lifting device, a tip sand suction port having a large opening in the lower half of the sand collecting pipe is opened to facilitate the inflow of external sediment.
補吸水筒部に吸砂口を備えた覆水路揚泥装置において、該補吸水筒部吸砂口と集砂管部吸砂口が分断される構成となる場合は、該集砂管の吸砂口上流端上辺から該補吸水筒の吸砂口に至る間に、外方に突出させた導水庇を設け、沈殿物の安息角の影響もあり該導水庇下にできる空隙を初期流水路にして、該補吸水筒部吸砂口の沈殿物排除で得られるようになる沈澱物の上方水を、該集砂管の先端吸砂口及び吸砂口上辺に導き、沈殿物吸入が該集砂管吸砂口に連続しやすくする。 In a drainage mud apparatus having a sand suction port in the auxiliary water suction cylinder part, when the auxiliary water suction cylinder part sand suction port and the sand collection pipe part sand suction port are separated, the suction pipe of the sand collection pipe is absorbed. Between the upper end of the sand mouth and the sand suction mouth of the auxiliary water sucking pipe, there is provided a water conduit that protrudes outward, and there is an influence of the angle of repose of the sediment, and the gap that can be under the water conduit is the initial flow channel Then, the upper water of the precipitate that is obtained by removing the sediment at the auxiliary suction cylinder portion sand suction port is led to the tip sand suction port and the upper side of the sand suction port of the sand collecting pipe, and the sediment suction is Make it easy to continue to the sand collecting pipe.
又、スリット状吸砂口を備えた集砂管においては、該スリット状吸砂口の開窄により、該集砂管が上下に分割される形になるために、上下集砂管の保持補強が必要であり、該集砂管上下をつなぐ形で集砂管外部に設けるつなぎリブ、或は支承物等の該吸砂口に当接する周辺部を、外方及び上方に広く開窄した貫通空隙部を作り、該貫通空隙部を通過した該集砂管外の流入水が、リブ、或は支承物を越した位置の該集砂管外沈殿物を洗掘する状態で該吸砂口に流入するようにして、円滑な吸砂作用の連続化を図る。 In addition, in the sand collecting pipe provided with the slit-shaped sand suction port, the sand collecting pipe is divided into upper and lower parts by the constriction of the slit-shaped sand suction port. And the peripheral part that contacts the sand suction port, such as a connecting rib provided outside the sand collecting pipe in a form that connects the upper and lower parts of the sand collecting pipe, or a through-opening that is widened outward and upward The sand suction port is formed in a state in which the inflow water outside the sand collecting pipe that has passed through the through gap part scours the sediment outside the sand collecting pipe at a position beyond the rib or support. In order to flow smoothly into the sand, a smooth sand-absorbing action is achieved.
更に、集砂管上辺には、該集砂管との間に通水路となる間隙を設けた給水カバーを冠設し、或いは、該集砂管上方に近接し、下辺を開窄開放した円環状外部給水管を該集砂管の全長、或は、上流側の一定区間に載置し、該給水カバー下の通水路隙間、或いは、該給水管に沈殿物の上方水を供給できるようにした供給水管を立設する等して、該集砂管の吸砂口上辺に近接した位置から、沈澱物の浸透水距離を短くして外部給水を行なうことで、吸砂口から吸入される浸透水量を増やし、集砂管の全長、又は、上流側補吸水筒寄りの一定区間の沈殿物吸入量を増加させる。 Further, a water supply cover provided with a gap serving as a water passage between the sand collecting pipe is crowned on the upper side of the sand collecting pipe, or a circle in which the lower side is closed and opened close to the upper side of the sand collecting pipe. An annular external water supply pipe is placed on the entire length of the sand collecting pipe or a fixed section on the upstream side so that the water passage clearance under the water supply cover or the upper water of the sediment can be supplied to the water supply pipe. If the water supply pipe is externally supplied from a position close to the upper side of the sand collecting port of the sand collecting pipe, for example, by standing the water supply pipe, the water is sucked from the sand sucking port. Increase the amount of osmotic water, increase the total length of the sand collection pipe, or increase the amount of sediment inhaled in a certain section near the upstream side suction pipe.
縦形揚泥装置の場合においては、下方端で集砂管を介して連通し、並立する形の補吸水筒と送泥管との間を、該補吸水筒の吸水口下から、下方端を該集砂管に近接した高さ位置までの間、両側面に側板を設けてふさぎ縦方向の空間水路を形成し、該装置が沈澱物に深く埋没した際に、沈澱物の上方水を該集砂管近くまで導入供給して、介在する沈澱物の浸透水通過距離を短くして、該集砂管吸砂口への沈澱物の吸入量を増加させる。 In the case of the vertical mud lifting device, the lower end communicates with the sand collecting pipe, and the lower end is connected between the auxiliary water absorbing cylinder and the mud feeding pipe arranged side by side from the water inlet of the auxiliary water absorbing cylinder. A side plate is provided on both sides to form a vertical space water channel up to a height position close to the sand collecting pipe, and when the device is deeply buried in the sediment, the upper water of the sediment is By introducing and supplying the sand collecting pipe to the vicinity thereof, the permeated water passage distance of the existing sediment is shortened, and the amount of the sediment sucked into the sand collecting pipe is increased.
又、前記の側板に替えて、補吸水筒と送泥管全体を断面長円形の給水囲いカバーで囲い、沈澱物の上方水を集砂管吸砂口の全周囲上辺に近接させて給水し、吸砂口全体からの沈殿物吸入を促進することもできる。 Instead of the side plate, the auxiliary water absorption cylinder and the entire mud pipe are enclosed by a water supply enclosure cover with an oval cross section, and the water above the sediment is supplied close to the upper edge of the sand collection pipe. In addition, it is possible to promote the inhalation of sediment from the entire sand suction port.
前述するように本発明では、集砂管吸砂口の開口高さ位置による吸砂能力調整、縦方向吸砂口を設けた水路での通水稼働初期の管内閉塞の解消、先端吸砂口や給水カバーによる集砂管上流側の吸砂能力の向上、補吸水筒部吸砂口から集砂管吸砂口への沈澱物吸入の円滑連続化等により、この種揚砂揚泥装置の実用的集砂距離を伸ばし、吸入濃度の向上、安定化ができた。 As described above, in the present invention, the sand absorption capacity is adjusted according to the opening height position of the sand collecting pipe suction port, the blockage in the initial stage of water flow operation in the water channel provided with the vertical direction sand suction port is eliminated, and the tip sand suction port This type of sand pumping equipment is improved by improving the sand absorption capacity upstream of the sand collection pipe with a water supply cover, and smoothing the continuous suction of sediment from the suction pipe to the sand collection pipe. The practical sand collection distance was extended, and the inhalation concentration was improved and stabilized.
以下、本発明の実施形態を図１〜図１５に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS.
本発明の第１実施例は、図１に三面図を示し、集砂管１Ａ及び補吸水筒２Ａの各部断面図を図２、図３に示すような覆水路揚泥装置であって、沈殿物が発生する水底に設置し、送泥管３Ａのフランジ部を揚水源に接続して使用するものであり、集砂管３Ａの一部、或は全部がうまり、補吸水筒２Ａの吸水口５が沈殿物上の水中にある状態で通水稼働させ、周辺沈殿物を回収除去する装置である。 FIG. 1 shows a three-sided view of the first embodiment of the present invention, and is a water-carrying mud pumping device as shown in FIG. 2 and FIG. 3 showing sectional views of the sand collecting pipe 1A and the auxiliary water absorption cylinder 2A. It is installed on the bottom of water where objects are generated, and the flange part of the mud pipe 3A is connected to the pumping source for use, and part or all of the sand collecting pipe 3A is filled, and the water absorption of the auxiliary water absorption cylinder 2A This is a device that allows water to flow in a state where the mouth 5 is in the water on the sediment, and collects and removes the surrounding sediment.
集砂管１Ａの送泥管３Ａに近い部分には、図２（二）図に示すように集砂管１Ａの直下部に管路方向に開窄した吸砂口６があり、（ホ）図に示す断面Ｂ部では、取扱い沈殿物の安息角を考慮して、装置休止時に外部沈殿物が自然には崩れ込みにくい高さ位置の両側に吸砂口６を開窄しており、図３の（へ）図に示す断面Ｃ部では、装置休止時に外部沈殿物が集砂管１Ａ内に自然に崩れ込む高さ位置に、給砂口６が開窄されている。 In the portion near the mud pipe 3A of the sand collecting pipe 1A, there is a sand suction port 6 narrowed in the direction of the pipe line immediately below the sand collecting pipe 1A as shown in FIG. 2 (2). In the section B shown in the figure, taking into account the angle of repose of the treated sediment, the sand suction ports 6 are constricted on both sides at a height where it is difficult for the external sediment to collapse naturally when the apparatus is at rest. In the section C shown in Fig. 3 (f), the sand supply port 6 is constricted at a height position where the external sediment naturally collapses into the sand collecting pipe 1A when the apparatus is stopped.
集砂管１Ａが埋没状態の通水稼働時において、沈殿物が該集砂管１Ａに流入するためには、吸砂口６が直下部にある（二）図の断面Ａ部では、沈殿物からの浸透水が当該沈殿物粒子を浮上させ、流入させる速度が必要であり、（ホ）図断面位置Ｂ部では、沈殿物は自然には崩れ込めないけれども、浸透水又は流入水速度が沈殿物を横移動させ得る速度であれば集砂管内に流入する。 When the sand collecting pipe 1A is in a buried water flow operation, in order for the precipitate to flow into the sand collecting pipe 1A, the sand suction port 6 is located directly below ((2)) The osmotic water from the surface needs to float and flow the sediment particles. (E) At the position B in the cross section of the figure, the sediment does not collapse naturally, but the osmotic water or inflow water velocity is settled. If it can move the object laterally, it will flow into the sand collection tube.
（へ）図の断面Ｃ部に於いては、沈殿物は自然に集砂管１Ａ内に滑落流入し、管内に堆積した該沈澱物は、吸入位置が高い分、管内の安息角稜線長さが長く、流動水との混合流域が広く、混合排除されやすい。 (F) In the section C of the figure, the sediment naturally slides down into the sand collecting pipe 1A, and the sediment deposited in the pipe has a length of the repose angle ridgeline in the pipe because the suction position is high. Is long, has a wide mixed basin with flowing water, and is easy to eliminate mixing.
補吸水筒２Ａには、管路方向に沿った縦方向の吸砂口７を開窄し、該補吸水筒２Ａ内には（チ）図に断面を示すように仕切板４Ａを設けて、非吸砂口側流水路ｄと吸砂口側流水路ｅに分割して、下方端の図１（イ）図に示すｆ部で合流し混合させる。 In the auxiliary water absorption cylinder 2A, a vertical sand suction port 7 along the pipe direction is closed, and a partition plate 4A is provided in the auxiliary water absorption cylinder 2A as shown in the cross section of FIG. It divides | segments into the non-sand-absorption side flow channel d and the sand-absorption side flow channel e, and joins and mixes by the f part shown to FIG.
該ｆ部位置の集砂管１Ａ下辺には、一段大きく開口させた先端吸砂口１０を開口させて外部沈殿物の流入を容易にする。 At the bottom of the sand collecting pipe 1A at the position f, a tip sand suction port 10 that is opened one step larger is opened to facilitate the inflow of external sediment.
又、吸砂口７と吸砂口６の上流端上辺間には、導水庇８を、図３（ト）図に示すように庇外方を低く傾斜させて、集砂管１Ａ寄りに沈澱物のない庇下空隙ａを作る形で配設し、吸砂口７から吸砂口６への沈澱物吸入のつながりを図る。 Further, between the upstream side of the sand suction port 7 and the sand suction port 6, a water conduit 8 is inclined toward the sand collecting pipe 1 </ b> A by inclining the outer side as shown in FIG. It arrange | positions in the form which makes the underarm space | gap a which does not have a thing, and the connection of the sediment suction | inhalation from the sand suction port 7 to the sand suction port 6 is aimed at.
集砂管１Ａは断面（ホ）図及び（へ）図に示す部分では、スリット状の吸砂口６に依って上下に分割された状態であり、該上下を保持、或は、吸砂口６の間隔を保持するためのつなぎリブ９の該吸砂口６に当接する部分を、前面方向及び上方に大きく開窄して空隙ｂを設けた形態にすることにより、該空隙部ｂを通過した外部流入水が、つなぎリブ９を越えた位置の外部沈殿物を洗掘、或いは、掃流して該吸砂口６に流入し、つなぎリブ９前後の沈殿物の吸入が円滑につながる。 The sand collecting pipe 1A is divided into upper and lower portions by a slit-shaped sand suction port 6 in the sections shown in the cross-sectional (e) and (f) diagrams, and the upper and lower sides are held or the sand suction port The portion of the connecting rib 9 for holding the gap 6 that is in contact with the sand suction port 6 is greatly narrowed in the front direction and upward to provide the space b, thereby passing through the space b. The external inflow water thus scoured or swept away the external sediment at a position beyond the connecting rib 9 and flows into the sand suction port 6, and the suction of the sediment around the connecting rib 9 is smoothly connected.

又、集砂管１Ａの（ホ）図Ｂ部断面及び（へ）図Ｃ部断面に図示する吸砂口６は、図示するように集砂管６の両側に設けずに、片側だけとすることや、Ａ部又はＢ部断面のいずれかの高さに統一すること、全体を傾斜させた吸砂口とすることができる。
