Description
本発明は、ダム、湖沼、河川、産業施設水槽等の水底沈殿物を回収又は除去するための揚泥装置に関するものである。 TECHNICAL FIELD The present invention relates to a mud lifting device for collecting or removing water bottom sediment from dams, lakes, marshes, rivers, industrial facilities tanks, and the like.
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、これ等沈殿物の回収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 submerged sediment, such as sediment flowing into dams due to heavy rain and debris flow, mud from lakes and marshes, collection and removal of sediment in rivers, and mud in industrial facilities tanks. Many types of devices are provided for collecting and removing these precipitates.
The inventor of the present application has also obtained a patent No. 3895505 that enables a wide range of sand and mud and has filed a Japanese Patent Application No. 2015-116078, but this is not satisfactory and is improved.
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上下方向水路部である補吸水筒を立設し、該補吸水筒壁に沿って窄穴配列した孔やスリット状の吸砂口を備え、該下方端を所定方向に転向させた該吸入管の管底又は管側壁にライン状に窄穴配列した孔やスリット状の吸砂口を備えた集砂管部を設け、或いは、該集砂管部を設けることなく送泥管に接続した該吸入管下流端を落差やサイフォン、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連通し、沈殿物を回収除去する揚泥装置における課題である。 An auxiliary water absorption cylinder, which is a vertical waterway that maintains the upstream end water suction port of the suction pipe at a height that will not be buried in sediment, is erected, and holes or slits are formed along the wall of the auxiliary water absorption cylinder. A sand collecting pipe portion provided with a hole formed in a line or a slit-shaped sand absorbing hole is provided at the bottom or side wall of the suction pipe having a sand port, the lower end of which is turned in a predetermined direction, Alternatively, the downstream end of the suction pipe connected to the mud pipe without providing the sand collecting pipe portion is 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 problem in a mud lifting device that collects and removes water.
補給水筒部に吸砂口を開口させた揚泥装置においては、該補吸水筒が縦方向水路であるが故に、装置休止中の堆積により吸砂口から侵入する沈殿物が、該補吸水筒内底部に堆積しやすく、閉塞状態になりやすいために、稼働開始時に揚水不能になることや、吸水に時間を要し円滑さを欠く大きな問題がある。 In the evacuation device in which the sand-absorbing port is opened in the make-up water-cylinder portion, since the auxiliary water-absorbing cylinder is a vertical waterway, sediment invading from the sand-absorbing port due to accumulation while the apparatus is inactive is generated by the auxiliary water-absorbing cylinder. Since it easily accumulates on the inner bottom and is likely to be in a closed state, there are serious problems that water cannot be pumped at the start of operation and that it takes time to absorb water and lacks smoothness.
段落［０００４］の揚泥装置の中、補吸水筒下方端を所定方向に転向させた下流に、吸砂口を開口させた集砂管部を設けて、長い距離の揚泥を行う揚泥装置（以降“覆水路揚泥装置”と称呼する）にあっては、揚水源に近い該集砂管下流端吸砂口が最も強く吸引され、該吸砂口上方がすり鉢状に開放され、該吸砂口より上流側は吸砂されなくなる“吸い破り現象”を生じやすくなる課題がある。 In the mud lifting apparatus of paragraph [0004], a sand collecting pipe section having an open sand absorbing port is provided downstream of turning the lower end of the auxiliary water suction cylinder in a predetermined direction to perform mud pumping over a long distance. In the device (hereinafter, referred to as a "coverage mud pumping device"), the sand suction pipe downstream end near the pumping source is sucked most strongly, and the upper part of the sand suction port is opened in a mortar shape, There is a problem that the upstream side of the sand-absorbing port is liable to cause a "suck-break phenomenon" in which sand is not absorbed.
また、段落［０００４］の揚泥装置の中、吸砂口を設けた補吸水筒の下方端最深部に、下方に向けた吸砂口を開口させ、或いは、該最深部に吸砂口を設けないで反転上昇させて、揚泥する形の揚泥装置（以降“縦形揚泥装置”と称呼する）においても、最深部の吸砂口、或いは、補給水筒部だけでの吸砂では吸砂濃度が低すぎる問題があり、補吸水筒に吸砂口を設け吸砂濃度を上げれば、稼働休止中の堆砂による該補吸水筒内底部の閉塞が生じやすくなる問題がある。 Further, in the mud lifting apparatus of paragraph [0004], a downwardly directed sand suction port is opened at the deepest portion of the lower end of the auxiliary water suction cylinder provided with the sand suction port, or a sand suction port is formed at the deepest portion. Even in a mud pump that lifts up and raises mud without providing it (hereinafter referred to as a “vertical mud pump”), if the sand is sucked only at the deepest part of the suction port or only in the makeup water bottle, There is a problem that the sand concentration is too low, and if the sand absorption port is provided in the auxiliary water absorption cylinder to increase the sand absorption concentration, there is a problem that the bottom of the auxiliary water absorption cylinder is likely to be blocked by sediment during suspension of operation.
本発明では、吸砂口をライン状に開窄配列した補吸水筒内水路に、該水路に沿った仕切りを設け、吸砂口を開窄した側の吸砂口側流水路と、吸砂口を設けず上方水を吸入し通水する非吸砂口側流水路に分割し、該補吸水筒下辺の仕切り下方端で両水路を合流させ、吸入水と吸入沈殿物を混合させる。 In the present invention, a partition is provided along the water passage in the auxiliary water suction cylinder in which the sand suction opening is arranged in a line-like manner, and the sand suction opening side flowing water passage on the side where the sand suction opening is closed, It is divided into a non-sand-absorbing-port-side flow channel through which upper water is sucked and passed without a port, and both channels are joined at the lower end of the partition on the lower side of the auxiliary water absorption cylinder to mix the suction water and the suction sediment.
長い距離範囲の沈殿物を回収除去することや、ポイント的小範囲を濃度高く吸砂吸泥することは、本願発明のみで達成できるものではなく、分割別願する発明を併用する。 Recovering and removing sediment in a long distance range and absorbing sand and mud at a high concentration in a small point area can not be achieved only by the present invention, and the invention separately divided and applied separately is also used.
前述するように本願発明では、沈殿物に埋没する状態で水中沈殿物を回収除去する揚泥装置の、吸砂口を開口させた補吸水筒の閉塞を防止することに依り、装置稼働初期の通水、吸砂の円滑化を図ることで安定した運転が確保でき、覆水路揚泥装置においては吸砂距離の増加、最深部に下方に向けた吸砂口を設けた縦形揚泥装置においては、吸砂濃度の向上ができる効果がある。 As described above, according to the present invention, the mud lifting device that collects and removes the submerged sediment in a state where it is buried in the sediment, by preventing the supplementary water absorption cylinder having the sand absorption opening from being closed, in the initial operation of the device. Stable operation can be ensured by smoothing water passage and sand absorption.In the case of a flooded mud lifting device, the sand absorption distance is increased, and in the vertical mud lifting device provided with a sand absorption port directed downward at the deepest part. Has the effect of improving the sand absorption concentration.
