Description
本発明は、浮体構造物の製造方法に関するものである。 The present invention relates to a method for manufacturing a floating structure.
従来から、船のような浮体構造物は、造船ドックで製造され、造船ドックに水を注入することにより進水させられるようになっている（下記の特許文献１参照）。 Traditionally, floating structures such as ships have been manufactured in shipbuilding docks and launched by injecting water into the dock (see Patent Document 1 below).
しかしながら、特許文献１に記載された製造方法では、１つの浮体構造物を製造して進水し終わるまで、造船ドックで次の浮体構造物を製造することは難しく、大量生産には適していないという問題点がある。 However, the manufacturing method described in Patent Document 1 has the problem that it is difficult to manufacture the next floating structure at the shipbuilding dock until one floating structure has been manufactured and launched, making it unsuitable for mass production.
そこで、本発明は、上記事情に鑑みてなされたものであり、大量生産をすることが可能な浮体構造物の製造方法を提供する。 The present invention was made in consideration of the above circumstances, and provides a method for manufacturing floating structures that can be mass-produced.
上記目的を達成するために、本発明は以下の手段を採用している。
すなわち、本発明に係る浮体構造物の製造方法は、陸上の作業場で少なくとも浮力を発生し得る浮体構造物を製造し、前記浮体構造物を水域に進水させる、浮体構造物の製造方法であって、前記水域の前記作業場に隣接する場所に設けられた、前記浮体構造物を載置可能な載置部を水面から露出した状態と、水中に位置した状態と、を取りうるリフトを用い、前記リフトの前記載置部を水面から露出した状態から水中に位置した状態として前記浮体構造物を進水させつつ、前記作業場で別の浮体構造物を製造可能とする。
In order to achieve the above object, the present invention employs the following means.
In other words, the method for manufacturing a floating structure according to the present invention is a method for manufacturing a floating structure in which a floating structure capable of generating at least buoyancy is manufactured at a work site on land, and the floating structure is launched into a body of water, and a lift is used, which is provided in a location adjacent to the work site in the body of water, and which has a mounting section on which the floating structure can be placed, which can be exposed above the water surface or positioned underwater, and the floating structure is launched by changing the mounting section of the lift from a state exposed above the water surface to a state positioned underwater, making it possible to manufacture another floating structure at the work site.
このように構成された浮体構造物の製造方法では、リフトによる浮体構造物の進水作業と、作業場での別の浮体構造物の製作作業と、を同時並行でできる。このため、スムーズ且つ迅速に浮体構造物の製造を進められ、大量生産をすることができる。 With this floating structure manufacturing method, the launching of a floating structure using a lift and the fabrication of another floating structure in the workshop can be carried out simultaneously. This allows for smooth and rapid manufacturing of floating structures, enabling mass production.
また、本発明に係る浮体構造物の製造方法は、前記作業場から前記リフトの前記載置部に前記浮体構造物を移動可能とする溝が前記作業場及び前記載置部に設けられていてもよい。 Furthermore, the floating structure manufacturing method according to the present invention may include providing a groove in the work area and the storage area that allows the floating structure to be moved from the work area to the storage area of the lift.
このように構成された浮体構造物の製造方法では、作業場からリフトの載置部まで繋がる溝に沿って浮体構造物を移動させることができるため、作業性を高めることができる。 This method of manufacturing a floating structure configured in this way allows the floating structure to be moved along a groove that connects the work area to the lift's mounting section, thereby improving workability.
また、本発明に係る浮体構造物の製造方法は、前記作業場から前記リフトの前記載置部に前記浮体構造物を移動可能とするベルトコンベアが前記作業場及び前記載置部に設けられていてもよい。 Furthermore, the floating structure manufacturing method according to the present invention may also include providing a belt conveyor in the work area and the storage area, which enables the floating structure to be moved from the work area to the storage area of the lift.
このように構成された浮体構造物の製造方法では、作業場からリフトの載置部まで繋がるベルトコンベアで浮体構造物を移動させることができるため、作業性を高めることができる。 In this floating structure manufacturing method, the floating structure can be moved on a conveyor belt that connects the work area to the lift's loading section, improving workability.
本発明に係る浮体構造物の製造方法によれば、大量生産をすることができる。 The floating structure manufacturing method of the present invention allows for mass production.
以下、本発明の一実施形態に係る浮体構造物の製造方法について、図面を参照しつつ説明する。
まず初めに浮体構造物１を製造する際に用いられる設備について、説明を行う。浮体構造物１を製造する設備は、岸壁などの陸地からなる作業場３１と、作業場３１に隣接する水域Ｗと、を有する。作業場３１は、図１では図示しないものの、工場等の建屋を備えていてもよく、少なくとも浮力を発生し得る構成となるように組み立てられた浮体構造物１を形成するためのエリアである。
Hereinafter, a method for manufacturing a floating structure according to one embodiment of the present invention will be described with reference to the drawings.
First, we will explain the facilities used in manufacturing the floating structure 1. The facilities for manufacturing the floating structure 1 include a work area 31 consisting of land such as a quay, and a water area W adjacent to the work area 31. Although not shown in Fig. 1, the work area 31 may include a building such as a factory, and is an area for forming the floating structure 1 assembled so as to have at least a configuration capable of generating buoyancy.
水域Ｗは、海や湖などであり、浮体構造物１が進水させられるエリアである。水域Ｗには、浮体構造物１を進水可能とするリフト２が設けられている。図２は、リフト２の構成を示す概略図である。
図２に示すように、リフト２は、浮体構造物１が載置可能なリフト底盤（載置部）２３と、複数の杭２１と、センターホールジャッキ２２と、ロッド２２ａと、を有している。複数の杭２１は、鉛直方向に延び、上端部にセンターホールジャッキ２２が固定され、下端部が水域Ｗの海底地盤Ｇに打ち込まれ、海底に設置される。ロッド２２ａは、一端がリフト底盤２３に固定され、他端がセンターホールジャッキ２２に挿通されている。このようにして、リフト底盤２３は、センターホールジャッキ２２でロッド２２ａが引っ張られることで水域Ｗの水面から露出した状態と、センターホールジャッキ２２でロッド２２ａの移動が許容され、水域Ｗの水中に位置する状態と、を取りうるよう構成されている。つまり、センターホールジャッキ２２は、杭２１の反力を利用して、リフト底盤２３を上下に移動可能としている。リフト底盤２３が下方に移動し、水中に移動することによって、リフト底盤２３上に載置された浮体構造物１は、進水可能とされている。
The water area W is an ocean, a lake, or the like, and is an area where the floating structure 1 can be launched. A lift 2 that enables the floating structure 1 to be launched is provided in the water area W. Figure 2 is a schematic diagram showing the configuration of the lift 2.
As shown in Figure 2, the lift 2 has a lift base (support portion) 23 on which the floating structure 1 can be placed, multiple piles 21, a center-hole jack 22, and a rod 22a. The multiple piles 21 extend vertically, have the center-hole jack 22 fixed to their upper ends, and are installed on the seabed by being driven into the seabed G of the water area W. One end of the rod 22a is fixed to the lift base 23, and the other end is inserted into the center-hole jack 22. In this way, the lift base 23 is configured to be able to assume two states: a state in which the rod 22a is exposed above the water surface of the water area W when pulled by the center-hole jack 22, and a state in which the rod 22a is allowed to move by the center-hole jack 22 and is located underwater in the water area W. In other words, the center-hole jack 22 uses the reaction force of the piles 21 to move the lift base 23 up and down. The lift base plate 23 moves downward and into the water, so that the floating structure 1 placed on the lift base plate 23 can be launched.
なお、浮体構造物１を作業場３１からリフト２のリフト底盤２３へ種々の方法を用いて移動可能としてもよい。例えば、上下昇降するジャッキ及び水平移動用ジャッキが搭載された設置台の上に浮体構造物１を載せて、スライド移動させる方法（ＩＰ－ＣＣＶシステム）を用いてもよい。この他、エアーキャスターが設けられた設置台の上に浮体構造物１を載せて、ジャッキまたはウィンチを使用して移動させる方法や浮体構造物１を載せた設置台をベルトコンベアで移動させたり、設置台に無限軌道や車輪等を設けて移動させたりする方法を用いてもよい。作業場３１の製造場所からリフト２までの道のり、及びリフト２のリフト底盤２３には、上記の移動装置が活用できるように、ＩＰ－ＣＣＶシステム、エアーキャスター、無限軌道や車輪の走行が可能なレールや溝を設けたり、ベルトコンベア等の装置を取り付けたりしておくことが好ましい。 The floating structure 1 may be moved from the work site 31 to the lift base 23 of the lift 2 using various methods. For example, a method (IP-CCV system) may be used in which the floating structure 1 is placed on a mounting platform equipped with vertically moving jacks and horizontally moving jacks and then slid to move. Alternatively, the floating structure 1 may be placed on a mounting platform equipped with air casters and moved using a jack or winch, or the mounting platform with the floating structure 1 may be moved by a belt conveyor, or the mounting platform may be equipped with caterpillars, wheels, or the like. It is preferable that the path from the manufacturing site in the work site 31 to the lift 2 and the lift base 23 of the lift 2 be provided with rails or grooves on which the IP-CCV system, air casters, caterpillars, or wheels can travel, or that a belt conveyor or other device be attached, so that the above-mentioned moving devices can be utilized.
次に、本発明の一実施形態に係る浮体構造物の製造方法を説明する。
図１に示すように、浮体構造物１のうち、少なくとも浮力を発生し得る構成を作業場３１で製造する。作業場３１で製造した、少なくとも浮力を発生し得る構成を有する浮体構造物１は、水域Ｗに設置されたリフト２の水面から露出したリフト底盤２３上に移動させられる。そして、リフト２のリフト底盤２３を降下させ、リフト底盤２３を水面から露出した状態から水中に位置した状態とすることで、浮体構造物１を水域Ｗに進水させる。水域Ｗへ浮体構造物１の進水をさせつつ、作業場３１では新たな浮体構造物（１の製造を開始する。上記の作業を繰り返すことによって、順次浮体構造物１を製造する。
Next, a method for manufacturing a floating structure according to one embodiment of the present invention will be described.
As shown in Figure 1, at least the components of the floating structure 1 that are capable of generating buoyancy are manufactured in a work area 31. The floating structure 1 manufactured in the work area 31 and having at least the components that are capable of generating buoyancy is moved onto a lift base 23 that is exposed above the water surface of a lift 2 installed in a water area W. The lift base 23 of the lift 2 is then lowered, and the lift base 23 is changed from a state where it is exposed above the water surface to a state where it is located underwater, thereby launching the floating structure 1 into the water area W. While the floating structure 1 is being launched into the water area W, the work area 31 starts manufacturing a new floating structure 1. By repeating the above-mentioned work, floating structures 1 are manufactured one after another.
このように構成された浮体構造物の製造方法では、リフト２による浮体構造物１の進水作業と、作業場３１での別の浮体構造物１の製作作業と、を同時並行でできる。このため、スムーズ且つ迅速に浮体構造物１の製造を進められ、大量生産をすることができる。 In this floating structure manufacturing method, the launching of the floating structure 1 by the lift 2 and the production of another floating structure 1 in the workshop 31 can be carried out simultaneously. This allows the manufacturing of the floating structure 1 to proceed smoothly and quickly, enabling mass production.
また、作業場３１からリフト底盤２３まで繋がる溝に沿って浮体構造物１を移動させたり、作業場３１からリフト底盤２３まで繋がるベルトコンベアで浮体構造物１を移動させたりできるため、作業性を高めることができる。 In addition, the floating structure 1 can be moved along a groove connecting the work area 31 to the lift base plate 23, or on a belt conveyor connecting the work area 31 to the lift base plate 23, thereby improving workability.
また、リフト２を利用した進水では、浮体構造物１を吊るすことがないため、浮体構造物１に補強等をする必要がなく、補強の手間を省略して短工期で製造が可能であるとともに、低コストで量産が可能である。 Furthermore, when launching using the lift 2, the floating structure 1 does not need to be suspended, so there is no need to reinforce the floating structure 1. This eliminates the need for reinforcement work, allowing for manufacturing in a short period of time and mass production at low cost.
なお、上述した実施の形態において示した組立手順、あるいは各構成部材の諸形状や組み合わせ等は一例であって、本発明の主旨から逸脱しない範囲において設計要求等に基づき種々変更可能である。 Note that the assembly procedures, shapes, and combinations of the components shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.
