備期間を要す。Traditional methods obstruct traffic and cause traffic congestion, which can lead to complaints. Additionally, in order to secure a separate route, a new road will be constructed, which will require a long preparation period before construction can begin.
仮橋を設置する場合でも、その設置・解体に一般橋梁工
事の同程度の大規模な規制が必要となると同時に、多大
な費用が発生する。Even when a temporary bridge is installed, its installation and dismantling require the same large-scale regulations as for general bridge construction, and at the same time, large costs are incurred.
又、従来の仮橋では、小スパンに制限されていた。Furthermore, conventional temporary bridges are limited to small spans.

。Zero positioning is achieved by providing a telescopic mechanism on the legs of a module that divides an overpass into appropriate lengths (15m to 20m) to make it transportable. The module is mounted on a trolley such as a trailer and transported to a predetermined location.
立体交差部は、短期間に安全に設置できるよう、両側モ
ジュールに搭載された面材パネルを張り出す張り出し2
架設丁法を採用スる。Overhangs 2 are used to overhang the facing panels mounted on the modules on both sides of the grade-separated intersections so that they can be installed safely in a short period of time.
Adopt the construction method.
立体交差部を長スパン化及び軽量化するため、立体交差
部を吊構造とする。In order to make the intersection longer and lighter, the intersection will have a suspended structure.
[作 用]
仮橋設備を吊構造とし、梁構するに際し5で吊橋或は斜
張橋の架設工法を適用することにより、仮橋の支間長を
長大化すると共に、架設の簡略化を実現できる。[Function] By making the temporary bridge equipment a suspended structure and applying the construction method of suspension bridges or cable-stayed bridges in step 5 when constructing the beams, the span length of the temporary bridge can be increased and the construction can be simplified. can.

りステーケーブル4により品り構造とする。The temporary bridge has module M1 on the keyaki shown in Figures 1 and 2.
.. Install tower 1, which can be easily installed, on the side of the grade-separated intersection of the Mt~7 approach section (in the figure, it is shown as a collapsible type, but an assembled method is also possible), and backstay cable 2 is installed on the approach side. , the overpass 3 is 1. The structure is made up of stay cables 4 from tower l.

間長を調整できる。Figure 1 shows the case where the tower 1 is installed on both sides, and Figure 2 shows the case where it is installed on one side, and the force installed on both sides can be extended over a long span. Also, set the height of the tower to #J! The span length can be adjusted by twisting one knot.

In order to carry out erection in a short time, as shown in FIG. 4, the tower 1 is directly mounted on the module M by pushing it up using a jack 5 through a bottle coupling 6. In Fig. 5, the rectangular parallelepiped blocks 7 are stacked, and the tension bolt 8 is applied to resist the pressure m by metal touch (Fig. 6). Note that 16 is a hook structure for the tension bolt. .
