Description

本発明は、潜水士による捨石均しの作業効率の向上に資する補助装置に関する。 The present invention relates to an auxiliary device that contributes to improving the working efficiency of leveling by a diver.

防波堤や護岸など重力式の港湾構造物の設置に際しては捨石マウンドの構築が欠くことのできない作業となっている。捨石マウンドには基礎地盤の不陸を補正したり、構造物の荷重を分散したり、波や潮流による構造物底面付近の地盤の洗掘を防止する等の働きがあり、これらの働きにより構造物の安定した設置を実現している。捨石マウンドは構築初期には捨石が雑然と積み上げられた不陸の状態であるため、これを略の均一の高さ(+5cm〜−5cm)になるまで捨石の位置を変えたり組み直したりしながら天端を仕上げる捨石均しと呼ばれる作業が必要になる。 The construction of a rubble mound is indispensable when installing gravity-type harbor structures such as breakwaters and revetments. The rubble mound has functions such as correcting the unevenness of the foundation ground, distributing the load of the structure, and preventing scouring of the ground near the bottom of the structure due to waves and tidal currents. Realizes stable installation of objects. Since the rubble mound is in an unlanded state where rubble is piled up clutterly at the beginning of construction, the rubble mound is tempered while changing the position of the rubble and reassembling until it reaches a roughly uniform height (+5 cm to -5 cm). Work called rubble leveling to finish the edges is required.

従来、捨石均しは潜水士による手作業が中心であったが、港湾構造物の大規模化、大水深化などの流れを受け、近年では専用の捨石均し装置が開発されるなど一層の機械化が進展している(特許文献1、2参照)。これらの捨石均し装置によれば、人力を機械に置き換えることによる安全性の向上はもとより、施工能力の向上による工期の短縮やコストの低減を図ることができるというメリットがある。また機械の場合、視界の確保の必要がないため、潜水士が視認できないような暗い水域や濁った水域での作業にも対応が可能である。 Traditionally, rubble leveling has been centered on manual work by divers, but in response to the trend of large-scale harbor structures and deepening of water depth, a dedicated rubble leveling device has been developed in recent years. Mechanization is progressing (see Patent Documents 1 and 2). According to these rubble leveling devices, there is an advantage that the construction period can be shortened and the cost can be reduced by improving the construction ability as well as improving the safety by replacing the manpower with a machine. In the case of a machine, since it is not necessary to secure visibility, it is possible to cope with work in dark water or cloudy water where a diver cannot visually recognize.

しかし、捨石均し装置は高価であり、また操作のためのオペレータが別途必要になり、さらには装置の運搬や移動を担う起重機船の配備も必要になるなど、人件費と損料が大幅に増えるという問題もある。そのため、中小の施工者が施工することが多い小規模な現場などにおいては、捨石均し装置の施工能力が格段に向上した今日においても潜水士による捨石均しの需要は依然として高い。しかし、先に述べたとおり現場の状況によっては視界の確保が困難であるため、捨石均し作業の効率が上がらないという問題は残ったままである。 However, the rubble leveling device is expensive, and an operator for operation is required separately. In addition, it is necessary to install a hoist ship for transporting and moving the device, so labor costs and expenses are greatly increased. There is also a problem. Therefore, in small-scale sites where small and medium builders often perform construction, there is still a high demand for rubble leveling by divers even today when the construction capacity of the rubble leveling device has improved dramatically. However, as mentioned above, it is difficult to ensure visibility depending on the situation at the site, so the problem remains that the efficiency of the rubble leveling operation does not increase.

本発明は、潜水士の視界を確保することにより捨石均しの作業効率の向上に資する水中基礎捨石均し補助装置を提供することを目的とする。 An object of the present invention is to provide an underwater basic rubble leveling assisting device that contributes to improving the work efficiency of rubble leveling by ensuring the visibility of a diver.

本発明の水中基礎捨石均し補助装置は、一方向に延伸され、両端部が水密に封鎖された管と、前記管の内部に外部から給水するための給水孔と、前記管の長さ方向に所定の間隔をおいて設けられ、前記給水孔から前記管の内部に供給された水を外部に噴出させるための噴水孔と、前記管の長さ方向に所定の間隔をおいて設けられ、前記噴水孔から水が噴出する方向を照らす照明装置、を備えた構成である。 The underwater basic rubble leveling auxiliary device of the present invention is a pipe that is stretched in one direction and sealed at both ends in a watertight manner, a water supply hole for supplying water into the pipe from the outside, and a length direction of the pipe Are provided at predetermined intervals, and are provided at predetermined intervals in the length direction of the pipes, and fountain holes for ejecting water supplied to the inside of the pipes from the water supply holes, It is the structure provided with the illuminating device which illuminates the direction in which water ejects from the said fountain hole.

本発明の水中基礎捨石均し補助装置は、濁度が高く透明度が低い水域において基礎捨石均しを行う場合に、潜水士の視界を確保し、作業効率を向上させるために用いられる装置である。管は捨石均し作業を行う水深まで沈められ、噴出孔から真水もしくは比較的濁度の低い海水等を噴き出し、均し作業を行う水域の透明度を向上させる。同時に潜水士の手元や周囲の捨石を照明装置により明るく照らし出す。管は捨石マウンドの天端面に水平に置くことで均し定規とし使用することができる。 The underwater basic rubble leveling auxiliary device of the present invention is a device used to ensure the visibility of divers and improve work efficiency when performing basic rubble leveling in water areas with high turbidity and low transparency. . The pipe is submerged to the depth at which the rubble leveling operation is performed, and fresh water or seawater with relatively low turbidity is blown out from the ejection hole to improve the transparency of the water area where the leveling operation is performed. At the same time, the lighting device illuminates the divers' hands and surrounding rubble. The pipe can be used as a leveling ruler by placing it horizontally on the top of the rubble mound.

本発明の水中基礎捨石均し補助装置は、管が4つの面からなる矩形断面の形状であり、任意の面に前記照明装置が設けられ、前記任意の面に隣接する他の面に前記噴水孔が設けられている構成とすることができる。 The submerged basic rubble leveling auxiliary device of the present invention has a rectangular cross section of a pipe having four surfaces, the lighting device is provided on an arbitrary surface, and the fountain on another surface adjacent to the arbitrary surface. It can be set as the structure by which the hole is provided.

矩形断面の管は設置したときに位置と傾きが安定するため、照明方向と噴水方向を一定の方向に維持しやすくなる。 Since the position and inclination of the rectangular cross-section tube are stable, it is easy to maintain the illumination direction and the fountain direction in a certain direction.

本発明の水中基礎捨石均し補助装置は、前記任意の面と対向する面に当該面より大きな面積を備えた底板が設けられている構成とすることができる。 The underwater basic rubble leveling assisting device of the present invention may be configured such that a bottom plate having an area larger than the surface is provided on a surface facing the arbitrary surface.

底板には設置された管の安定度を高めるとともに、管を水中に沈めるときにバランサーの役割を果たし、照明装置が設けられた面を上向きに維持する機能がある。 The bottom plate has a function of increasing the stability of the installed tube and also serving as a balancer when the tube is submerged, so that the surface on which the illumination device is provided is maintained upward.

本発明の水中基礎捨石均し補助装置は、前記管には角型鋼管を用い、前記底板には鋼板を用いた構成とすることができる。 The underwater basic rubble leveling auxiliary device of the present invention may be configured such that a square steel pipe is used for the pipe and a steel plate is used for the bottom plate.

水中基礎捨石均し補助装置の構成の大部分を占める管および底板に土木建築分野において般用されている角型鋼管および鋼板を加工して用いることにより、装置製作にかかるコストを大幅に抑えることができる。 By processing and using square steel pipes and steel plates commonly used in the civil engineering and construction field for pipes and bottom plates, which occupy most of the configuration of the underwater foundation rubble leveling auxiliary equipment, greatly reduce the cost of equipment production. Can do.

本発明の水中基礎捨石均し補助装置は、作業船と、前記作業船に搭載された給水ポンプと、前記給水ポンプと前記管に設けられた給水孔を接続するホースと組み合わせることにより、水中基礎捨石均し補助システムを構成することができる。 An underwater foundation rubble leveling assisting device according to the present invention is combined with a work ship, a water supply pump mounted on the work ship, and a hose connecting a water supply hole provided in the water supply pump and the pipe.

本発明の実施の形態について添付した図面を参照しながら説明する。図1は水中基礎捨石均し補助システムの概念図である。本システムは、水中基礎捨石均し補助装置10(以下、装置10という。)と作業船12によって構成されている。装置10は均し定規として広く用いられている角形鋼管を加工したものであり、均し定規と同様に捨石マウンド14の天端に水平に設置して用いられる。ワイヤロープ16によって作業船12と連結されており、作業船12側から装置10の位置や向きを変更できるようになっている。作業船12にはジェットポンプ18が搭載されており、取水口20から採取した海水をポンプホース22を通じて装置10に圧送して供給する。装置10に供給された海水は装置10から水平方向に噴き出して、捨石均しの作業水域に浮遊する汚濁物質を拡散させ、作業水域の濁度を低下させる目的に用いられる。装置10にはLEDライト24が取り付けられており、捨石26の運搬や置換を行う潜水士28の手元やその周囲の作業水域を明るく照らし出す。 Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a conceptual diagram of an underwater basic rubble leveling system. This system is composed of an underwater rubble leveling assisting device 10 (hereinafter referred to as device 10) and a work boat 12. The device 10 is obtained by processing a square steel pipe that is widely used as a leveling ruler, and is installed horizontally at the top of the rubble mound 14 in the same manner as the leveling ruler. The work rope 12 is connected to the work ship 12 so that the position and orientation of the device 10 can be changed from the work ship 12 side. A jet pump 18 is mounted on the work ship 12, and seawater collected from a water intake 20 is pumped and supplied to the apparatus 10 through a pump hose 22. The seawater supplied to the apparatus 10 is ejected from the apparatus 10 in the horizontal direction, and is used for the purpose of diffusing contaminants floating in the working water area where the rubble is smoothed, thereby reducing the turbidity of the working water area. An LED light 24 is attached to the apparatus 10 and illuminates brightly the hand of the diver 28 who carries and replaces the rubble 26 and the surrounding working water area.

装置10は、図2および図3に示すように、矩形断面を有する角形の鋼管30を主体とする一方向に長く延伸された長尺物である。鋼管30の両端部は水密に封鎖されている。一方の端部には給水孔32が設けられており、給水孔32にはポンプホース18の一端が接続されている。 As shown in FIGS. 2 and 3, the apparatus 10 is a long object elongated in one direction mainly composed of a rectangular steel pipe 30 having a rectangular cross section. Both ends of the steel pipe 30 are sealed watertight. A water supply hole 32 is provided at one end, and one end of the pump hose 18 is connected to the water supply hole 32.

鋼管30の一方の側面には複数の噴出孔34が鋼管30の長さ方向に均等な間隔で形成されている。噴出孔34は鋼管30の側面を貫通し、鋼管30の内側と外側とを連通させる孔であり、給水孔32から鋼管30の内側に圧送される海水を鋼管30の側方に勢いよく噴出させる役割を有している。 A plurality of ejection holes 34 are formed on one side surface of the steel pipe 30 at equal intervals in the length direction of the steel pipe 30. The ejection hole 34 is a hole that penetrates the side surface of the steel pipe 30 and allows the inside and outside of the steel pipe 30 to communicate with each other. The seawater pumped from the water supply hole 32 to the inside of the steel pipe 30 is ejected vigorously to the side of the steel pipe 30. Have a role.

鋼管30の上面には複数のLEDライト22が取り付けられている。これらのLEDライト22は鋼管30の長さ方向に均等な間隔で全て鋼管30の側方に向けて配置されている。LEDライト22は、噴出孔34から海水が噴出する方向と同方向を照射し、捨石均し作業を行う潜水士の手元やその周囲を明るく照らし出す役割を有している。LEDライト22は、充電式電池等、電源を内蔵したタイプのものや作業船12に搭載された電源から電気の供給を受けるタイプのものなどを使用することができる。 A plurality of LED lights 22 are attached to the upper surface of the steel pipe 30. These LED lights 22 are all arranged toward the side of the steel pipe 30 at equal intervals in the length direction of the steel pipe 30. The LED light 22 irradiates in the same direction as the direction in which seawater is ejected from the ejection hole 34, and has a role of brightly illuminating the hand of the diver performing the rubble leveling operation and its surroundings. The LED light 22 may be of a type that incorporates a power source, such as a rechargeable battery, or a type that receives electricity from a power source mounted on the work boat 12.

鋼管30の底面には鋼板36が取り付けられている。鋼板36は鋼管30と略同じ長さであるが幅は大きく、底面の前後に張り出しており、底面より大きな面積を有している。鋼板36には捨石の上に設置した装置10が作業中に転倒したり向きを変えたりしないように安定度を高めるとともに、装置10を海中に沈めるときにバランサーとして機能し、LEDライト22が取り付けられた面を上向きにして着底させる役割を有する。 A steel plate 36 is attached to the bottom surface of the steel pipe 30. The steel plate 36 has substantially the same length as the steel pipe 30 but has a large width, projects over the front and back of the bottom surface, and has a larger area than the bottom surface. The steel plate 36 has a high stability so that the device 10 installed on the rubble does not fall or change direction during work, and functions as a balancer when the device 10 is submerged in the sea. It has the role of making the bottom surface face up.
