Description

本発明は、専用船を着桟させるドルフィン桟橋と綱取りドルフィンの間への一般船の侵入を防止するためのガードに関する。   The present invention relates to a guard for preventing a general ship from entering between a dolphin pier for landing a dedicated ship and a rope dolphin.

ドルフィン桟橋では、施工コストを低減するために、その長さをできるだけ短くする傾向がある。図5は、起動敷31の上を移動するシップローダー32を有する一対のドルフィン桟橋33,33を若干の間隔をおいて並設した場合を示す。この例では、ドルフィン桟橋33は、海上突出部分の長さは概ね100m程度に設定され、5,000t(DWT)程度のばら積み船を着桟させることができる。   Dolphin piers tend to be as short as possible to reduce construction costs. FIG. 5 shows a case where a pair of dolphin piers 33, 33 each having a ship loader 32 moving on the starting floor 31 are arranged in parallel at some intervals. In this example, the length of the sea projecting portion of the Dolphin Pier 33 is set to about 100 m, and a bulk carrier of about 5,000 t (DWT) can be docked.

しかし、このように、ドルフィン桟橋33の長さを短くした場合には、着桟する船の船尾がドルフィン桟橋33の端よりも沖合側に突出した状態となる。そこで、船尾側を係留するために、2船兼用の綱取りドルフィン34をドルフィン桟橋33から少し離れた位置に設けている。なお、35は防舷材、36はローディングアーム(図示省略)の旋回中心となる支持部を示す。   However, when the length of the dolphin pier 33 is shortened in this way, the stern of the ship to be berthed protrudes to the offshore side from the end of the dolphin pier 33. Therefore, in order to moor the stern side, a two-boat rope pulling dolphin 34 is provided at a position slightly away from the dolphin pier 33. Reference numeral 35 denotes a fender, and 36 denotes a support portion that serves as a turning center of a loading arm (not shown).

上述のように、沖合側に綱取りドルフィン34を設ける場合、ドルフィン桟橋33の沖合側の端部と綱取りドルフィン34との間(間隔K)がかなり開いてしまう。図5に示す例では、35m程度の間隔が開いている。このような場合、そのドルフィン桟橋33と綱取りドルフィン34の間に、専用船以外の一般船が侵入するおそれがあり安全上好ましくない。   As described above, when the rope take-up dolphin 34 is provided on the offshore side, a gap (interval K) between the end portion on the offshore side of the dolphin pier 33 and the rope take-up dolphin 34 is considerably opened. In the example shown in FIG. 5, an interval of about 35 m is open. In such a case, a general ship other than a dedicated ship may enter between the dolphin pier 33 and the rope dolphin 34, which is not preferable for safety.

本発明は、このような実情に鑑みてなされ、ドルフィン桟橋と綱取りドルフィン間への一般船の侵入を防止するための一般船侵入防止ガードを提供することを目的とする。   The present invention has been made in view of such a situation, and an object thereof is to provide a general ship intrusion prevention guard for preventing a general ship from entering between the Dolphin Pier and the rope dolphin.

(1)本発明の一般船侵入防止ガードは、ドルフィン桟橋Dの沖合側に綱取りドルフィン2を離間させて設けた場合の一般船侵入防止ガードにあって、
前記綱取りドルフィン2と、前記ドルフィン桟橋Dの沖合側の端部との間に、海上に浮遊しかつ海上から明確に視認できるガード3を、潮位に応じて高さ位置が可変となるように掛張したことを特徴とする。
(1) The general ship intrusion prevention guard according to the present invention is a general ship intrusion prevention guard when the rope take-up dolphin 2 is provided on the offshore side of the Dolphin Pier D,
A guard 3 that floats on the sea and is clearly visible from the sea between the rope take-up dolphin 2 and the end on the offshore side of the dolphin pier D so that the height position can be changed according to the tide level. It is characterized by being stretched.

このような構成によれば、ドルフィン桟橋Dと綱取りドルフィン2との間に一般船が侵入しようとしても、ガード3が掛張されていることを視認することで、侵入を断念せざるを得なくなるため、安全性が向上する。   According to such a configuration, even if a general ship tries to invade between the dolphin pier D and the rope dolphin 2, the invasion must be abandoned by visually confirming that the guard 3 is stretched. Safety is improved because it disappears.

(2)前記ガード3は、オイルフェンスであってもよい。オイルフェンスは海上に浮遊すると共に、海上から明確に視認することができるため、一般船の侵入を効果的に阻止することができる。 (2) The guard 3 may be an oil fence. Since the oil fence floats on the sea and can be clearly seen from the sea, the invasion of general ships can be effectively prevented.

(3)前記ガード3は、索部材に浮遊体を連設してなるものであってもよい。浮遊体を海上から視認することで、一般船の侵入を効果的に阻止することができる。 (3) The guard 3 may be formed by connecting a floating body to the rope member. By visually inspecting the floating body from the sea, the invasion of general ships can be effectively prevented.

本発明の一般船侵入防止ガードは、綱取りドルフィンとドルフィン桟橋の沖合側の端部との間に、海上に浮遊しかつ海上から明確に視認できるガードを、潮位に応じて高さ位置が可変となるように掛張するので、ドルフィン桟橋と綱取りドルフィンとの間に一般船が侵入しようとしても、ガードが掛張されていることを視認することで、侵入を断念せざるを得なくなるため、安全性が向上する。   The general ship intrusion prevention guard according to the present invention is a guard that floats on the sea and can be clearly seen from the sea between the rope take-up dolphin and the end of the dolphin pier, and the height position is variable according to the tide level. Because it is hung so that the general ship invades between the dolphin pier and the rope dolphin, it is necessary to give up the invasion by visually checking that the guard is hung. , Improve safety.

以下に、本発明の最良の実施の形態に係る一般船侵入防止ガードについて図面を参照しつつ詳細に説明する。
図1は、綱取りドルフィンとの間に一般船侵入防止ガードが掛張されたドルフィン桟橋Dの平面図である。図1において、符号1は桟橋本体、2は綱取りドルフィン、3は一般船の侵入を防止するための一対のガードで、オイルフェンスからなり、海上に浮遊しかつ海上から明確に視認できるように、潮位に応じて高さ位置が可変となるように桟橋本体1と綱取りドルフィン2の間に掛張されている。
Hereinafter, a general ship intrusion prevention guard according to the best mode of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view of a dolphin pier D in which a general ship intrusion prevention guard is stretched between the rope pulling dolphin. In FIG. 1, reference numeral 1 is a pier body, 2 is a rope take-up dolphin, 3 is a pair of guards for preventing invasion of a general ship, and consists of an oil fence so that it floats on the sea and is clearly visible from the sea. The bridge is stretched between the pier body 1 and the rope take-up dolphin 2 so that the height position can be changed according to the tide level.

このような構成により、ドルフィン桟橋Dと綱取りドルフィン2との間に一般船(大小を問わず)が侵入しようとしても、オイルフェンス3,3が掛張されていることを視認することで、侵入を断念せざるを得なくなるため、ドルフィン桟橋Dの周辺での安全性が向上する。オイルフェンス3,3は柔軟であるため、一般船が接触するようなことがあっても、船体が損傷することがない。また、図示のように、オイルフェンス3,3は、平面視にて、綱取りドルフィン2を頂点としてドルフィン桟橋Dの端部を底辺とする略二等辺三角形状をなすように掛張されるため、専用船の着桟に何ら障害となることはない。   With such a configuration, even if a general ship (regardless of size) tries to invade between the Dolphin Pier D and the Treadle Dolphin 2, by visually confirming that the oil fences 3 and 3 are stretched, Since the intrusion must be given up, safety around the Dolphin Pier D is improved. Since the oil fences 3 and 3 are flexible, the hull is not damaged even if a general ship comes into contact. Also, as shown in the figure, the oil fences 3 and 3 are stretched so as to form a substantially isosceles triangle shape with the rope dolphin 2 at the top and the end of the dolphin pier D as the bottom in plan view. , There will be no obstacle to the landing of the dedicated ship.

本実施の形態に示すドルフィン桟橋Dは、従来の2つのドルフィン桟橋(図5参照)を合体させて単一化したことを特徴としている。即ち、シップローダー(図示省略)を移動させるための起動敷4,4の間隔をできるだけ詰め、防舷材5が配設される箇所に所定間隔おきに立設される鋼管杭11に外装管を被嵌させて補強すると共に、幅方向に対向し合う鋼管杭11,11間に鋼管12を上下に複数本架け渡すと共に、筋交い状の鋼管で防舷材取付部5aを補強している。   The Dolphin Pier D shown in the present embodiment is characterized in that two conventional Dolphin Piers (see FIG. 5) are combined and unified. That is, as much as possible, the gap between the starting mats 4 and 4 for moving the ship loader (not shown) is reduced, and the outer pipe is attached to the steel pipe pile 11 that is erected at predetermined intervals at the place where the fender 5 is disposed. A plurality of steel pipes 12 are laid up and down between the steel pipe piles 11 and 11 facing each other in the width direction while being fitted and reinforced, and the fenders attaching part 5a is reinforced with bracing steel pipes.

このように構成されるドルフィン桟橋Dは、海上突出部分の長さ100m、幅23m程度に設定され、桟橋本体1の両側に18m程度の間隔をおいてそれぞれ4基の防舷材5を設けており、5,000t(DWT)程度のばら積み船を着桟させることができる。特に、図5に示す従来例よりも、幅寸法を大幅に短縮化(9m短縮)したことで、鋼材使用量を従来よりも格段に少なくすることができ、ドルフィン桟橋Dの施工コストを大幅に低減することができた。また、コスト低減化対策の一環として、桟橋本体1の全長をできるだけ短くして、ドルフィン桟橋Dの両側に着桟する2つの船の船尾を単一の綱取りドルフィン2で係留するようにしている点は、従来と同じである。なお、符号6はローディングアームの支持部を示す。   The Dolphin Pier D constructed in this manner is set to have a sea-projecting portion length of about 100 m and a width of about 23 m, and four fenders 5 are provided on both sides of the jetty body 1 with an interval of about 18 m. A bulk carrier of about 5,000 t (DWT) can be berthed. In particular, compared to the conventional example shown in FIG. 5, the width dimension has been greatly shortened (9 m shortened), so that the amount of steel used can be significantly reduced compared to the conventional case, and the construction cost of the Dolphin Pier D has been greatly increased. It was possible to reduce. As part of cost reduction measures, the pier body 1 is made as short as possible so that the stern of two ships landing on both sides of the Dolphin Pier D is moored by a single rope take-up Dolphin 2. The point is the same as before. Reference numeral 6 denotes a support portion of the loading arm.

図2は一般船侵入防止ガードが掛張されたドルフィン桟橋Dと綱取りドルフィン2の側面図、図3(a)は綱取りドルフィンの正面図、(b)は平面図、(c)側面図、図4はドルフィン桟橋Dの正面図である。これらの図に示すように、綱取りドルフィン2は、例えば、ドルフィン桟橋Dの沖合側の端部から概ね35m程度離間した位置に設けられている。ドルフィン桟橋Dの桟橋本体1は、所定間隔おきに海底に打設される複数の鋼管杭11によって支持され、その鋼管杭11が海面と接する部分は外挿管によって補強されており、綱取りドルフィン2に最も近い位置にある2本の鋼管杭11,11の外挿管には、オイルフェンス3,3の一端に接続された円環状のホルダー31,31が遊嵌状態に被嵌されている。   2 is a side view of the dolphin pier D and the rope take-up dolphin 2 on which a general ship intrusion prevention guard is stretched, FIG. 3 (a) is a front view of the rope take-up dolphin, (b) is a plan view, and (c) a side view. FIG. 4 is a front view of the Dolphin Pier D. As shown in these figures, the towing dolphin 2 is provided, for example, at a position approximately 35 m away from the offshore side end of the Dolphin Pier D. The pier body 1 of the dolphin pier D is supported by a plurality of steel pipe piles 11 placed on the seabed at predetermined intervals, and the steel pipe piles 11 are reinforced by extrapolation pipes so that the steel pipe piles 11 are in contact with the sea surface. The annular holders 31, 31 connected to one ends of the oil fences 3, 3 are fitted into the extrapolated pipes of the two steel pipe piles 11, 11 located at the closest positions to

一方、ドルフィン本体21は、海底に打設される複数の鋼管杭22によって海面上に少し突出した状態に支持されている。その鋼管杭22が海面と接する部分は外挿管によって補強されており、ドルフィン桟橋Dに最も近い位置にある2本の鋼管杭22,22の外挿管には、オイルフェンス3,3の他端に接続された円環状のホルダー32,32が遊嵌状態に被嵌されている。   On the other hand, the dolphin main body 21 is supported in a state of slightly projecting on the sea surface by a plurality of steel pipe piles 22 placed on the seabed. The portion where the steel pipe pile 22 is in contact with the sea surface is reinforced by the extrapolation pipe. The extrapolation pipe of the two steel pipe piles 22 and 22 located closest to the Dolphin Pier D is connected to the other end of the oil fences 3 and 3. The connected annular holders 32, 32 are fitted in a loosely fitted state.

このように、両端を円環状のホルダー31,32によって、それぞれ、鋼管杭11,22に対して位置可変に接続されたオイルフェンス3,3は、潮位に応じて高さ位置が可変となるため、常に、海上に浮遊して海上から明確に視認することができる。特に、本実施の形態では、既設のドルフィン桟橋D及び綱取りドルフィン2を有効に活用して、オイルフェンス3,3を掛張したので、コスト安に一般船の侵入を阻止することができる。なお、オイルフェンス3は単一であってもよく、オイルフェンス3に代えて、例えば、索部材に視認性を明確にするための標識等を立てた浮遊体を連設してもよい。   In this way, the oil fences 3 and 3 connected to the steel pipe piles 11 and 22 by the holders 31 and 32 having the annular ends at the both ends are variable in height according to the tide level. Always floating on the sea, you can see clearly from the sea. In particular, in the present embodiment, the existing dolphin pier D and the rope take-up dolphin 2 are effectively used and the oil fences 3 and 3 are hung, so that the general ship can be prevented from entering at low cost. In addition, the oil fence 3 may be single, and it may replace with the oil fence 3 and may provide the floating member which put the label | marker etc. for clarifying visibility on a cable member, for example.
