Higasitakasu Bridge spanned the Takasu Canal (34.70498, 135.40948) (
Autumn 2010, Autumn 2011).
Higasitakasu Bridge is composed of two spans; the bridge of the span of the north-east side is a movable bridge of draw types. The each bridge of both spans is seemingly a girder bridge of deck types.
北東側の岸から見た橋です。
橋脚上の門状のものが跳開装置で、その左側の建物が操作室のようです。
橋は、決まった時間帯に、かつ、船舶が通行する場合にのみ、引き上げられるようです。「操作時刻表」に表示された時刻に近づくと、二人の操作係らしき人が自転車に乗って橋へやってきました。そして、操作室で操作時刻が過ぎるまで待機すると、ふたたび自転車に乗ってどこかへ去っていきました。
This is the bridge which was seen from the bank of the north-east side.
The thing which is such as a gate on the pier is the draw device; the house of the left side of that is seemingly the operation house.
Only when the set times and ships go through the bridge, the bridge is seemingly drawn up. When time approached a time which was signed on "Operation Timetable", two men which are seemingly the operators came to the bridge by bicycle. And operators stay in the operation house until the operation time passed, then they again ride on the bicycles and were going away.
南西側の岸から見た橋です。
橋の両端には、踏切にあるような遮断機がありました。

乙津 (おとづ) 橋 :
Otozu Bridge
乙津川に、乙津橋が架かっていました (33.24099, 131.68062) (2010年 冬, 2011年 冬)。
乙津橋は7径間からなり、鋼製の下路式ポニー･ボーストリング･プラット･トラス橋が6径間で、上路式ガーダー橋が1径間で架けられていました。
Otozu Bridge spanned the Otozu River (33.24099, 131.68062) (
Winter 2010, Winter 2011).
Otozu Bridge is composed of seven spans; pony Pratt bowstring truss bridges which are made of steel of through types, were spanned at six spans; a girder bridge of deck types was spanned at one span.
トラス橋では下路式であっても横梁などがないために、トラス橋の径間でも開放感があります。
Because the truss bridges are through types but without upper beams etc. at the truss bridges, there is openness also at the truss bridge spans.
トラス橋には、ポニー形式のためと思われる垂直補剛材が設置されていました。
垂直補剛材は、各片側9本ある垂直材のうち、7本の外側に設置されていました。
At the truss bridges, pony types are probably the reason, vertical stiffeners were put on.
The vertical stiffeners were put on the outside of the seven vertical posts in which there are nine in each one side.
トラス橋の各銘板によると、西側 (左岸側) から4つは昭和26年 (1951年) に大分県が、東側 (右岸側) から2つは昭和29年 (1954年) に建設省が建造し、製作はすべて日本橋梁によるようです。
写真の上側が「大分縣建造」と標された銘板で、下側が「建設省建造」と標された銘板です。
乙津橋は、二等橋として架けられたようです。
According to the each maker's plates of the truss bridges; the four truss bridges from the west side (
the left bank side) were constructed by Ôita prefecture in 1951, the two truss bridges from the east side (
the right bank side) were constructed by Ministry of Construction in 1954, and the all bridges were made by Japan Bridge.
The upper side of the photograph is a maker's plate which said "大分縣建造" (Construction of Ôita prefecture), and the lower side is a maker's plate which said "建設省建造" (Construction of Ministry of Construction).
It seems that Otozu Bridge has been constructed as second class.
大分県が建造したトラス橋と、建設省が建造したトラス橋では、鋼材の種類や組み方が異なるのか、リベットの並び方などに異なる部分がありました。写真の上側は大分県が建造したもので、下側は建設省が建造したものです。
大分県が建造したトラス橋の銘板は上弦材の上面 (上側矢印) にありましたが、建設省が建造したトラス橋の銘板は上弦材と下弦材が結合されている部分 (下側矢印) にありました。建設省が建造したものでは、一般的な銘板の取り付け位置にはリベットが並ぶために、べつの位置に取り付けられたのかもしれません。
Because the types and the composing of the steel materials may be different, there are the different parts which are the arrangement of the rivets, etc., between the truss bridges which were constructed by Ôita prefecture and the truss bridges which were constructed by Ministry of Construction. The upper side of the photograph is a thing which was constructed by Ôita prefecture, and the lower side is a thing which was constructed by Ministry of Construction.
There were the maker's plates of the truss bridges which were made by Ôita prefecture on the upper sides of the upper chord members (upper side arrow); but there were the maker's plates of the truss bridges which were made by Ministry of Construction on the parts where the upper chord member and the lower chord member were united (lower side arrow). In the truss bridges which were made by Ministry of Construction, it may be that because the rivets were arranged at the general positions where the maker's plates are put on, those were put on the other positions.
写真の上側は大分県が建造したもので、下側は建設省が建造したものです。
添接板にも差異がありました。
The upper side of the photograph is a truss bridge which was constructed by Ôita prefecture, and the lower side is a truss bridge which was constructed by Ministry of Construction.
There were the differences also at the splice plates.
トラス橋の支承です。
写真の上側が固定支承で、下側 (手前) が可動支承 (ローラー支承) です。
These are the bearings of one truss bridge.
The upper side of the photograph is a fixed bearing; the lower side (this side) is an expansion bearing (roller bearings).
トラス橋の床版の裏側と、橋脚です。
This is the back of the slab of one truss bridge, and one pier.
橋の東端に架かるガーダー橋です。
This is the girder bridge which was spanned at the end of the east side of the bridge.
ガーダー橋の銘板です。
ガーダー橋は昭和29年 (1954年) に建設省が建造し、製作は日本橋梁によるようです。
This is the maker's plate on the girder bridge.
It seems that the girder bridge was constructed by Ministry of Construction in 1954, and it was made by Japan Bridge.
ガーダー橋の支承です。
写真の左側が可動支承で、右側が固定支承のようです。平面支承のようです。
These are the bearings of the girder bridge.
The left side of the photograph is seemingly an expansion bearing; the right side is seemingly a fixed bearing. The bearings seemingly are plane bearings.
ガーダー橋の床版の裏側と、橋台です。
ジベルらしきものがあるので、ガーダー橋は合成桁かもしれません。
This is the back of the slab of the girder bridge, and one abutment.
Because there are seemingly shear connectors, the girder bridge may be a composite girder bridge.
西側 (左岸側) の親柱です。
These are the newels of the west side (the left bank side) of the bridge.
東側 (右岸側) の親柱です。
大分県の資料によると、乙津橋の読みは「おとづはし」のようですが、親柱には「おとつはし」と標されていました。
乙津橋は、昭和30年 (1955年) 3月に完成したようです。
These are the newels of the east side (the right bank side) of the bridge.
According to data of Ôita prefecture, the reading of Otozu Bridge is seemingly "Otozu Hasi", but in one newel, it said "Ototu Hasi."
It seems that Otozu Bridge has been completed in March, 1955.
和田 (わだ) 旋回橋 :
Wada Revolving Bridge
兵庫運河に、西日本旅客鉄道 (JR西日本) の和田旋回橋が架かっていました (34.66025, 135.16712) (2010年 秋)。
和田旋回橋は2径間からなり、鋼製の上路式プレート･ガーダーが架けられていました。この橋は明治32年 (1899年) に開通し、以前は旋回式の可動橋だったようです。現在は、橋は橋台や橋脚に固定されて旋回しないようです。旋回のための機械装置もないようですが、橋脚の円周に沿ってレール状のものがありました。旋回のために使われていたものかもしれません。
Wada Revolving Bridge of West Japan Railway (JR West) spanned the Hyôgo Canal (34.66025, 135.16712) (
Autumn 2010).
Wada Revolving Bridge is composed of two spans; a plate girder which is made of steel of deck types was spanned. It seems that the bridge was opened in 1899; formerly, the bridge had been a movable bridge of revolving types. The now, the bridge was seemingly fixed to abutments and a pier, it cannot revolve. Also the rails on both ends of the bridge did not have a gap. The machinery for revolving does not seemingly exist; but there was a thing which is such as rails along the circle of the pier. It may be that the thing had been used to revolve.
