SOLUTION: A foundation of a bridge pier is built with a caisson C at first. Next, an anti-rolling device P during lifting of a main column steel pipe is installed. Then, an anchor bolt A for a supporting steel pipe for reaction frame is embedded. Next, reinforcing timbering 10 for supporting the reaction frame is embedded. Then, a damping steel pipe column 1 is installed. Thus, the concrete form can be simplified since no SRC is used and labor saving can be realized. In addition, erection of bridge girder can be performed after erecting the main column steel pipe and thus the period of work can be shortened.

STEP 6 (see FIGS. 11 and 12)

First, the pull-up and connection of the main column steel pipe U group is completed.

Next, the construction elevator E is extended.

Next, the center hole jack 45 'for lifting the main column steel pipes on both sides is arranged at the position where the other main column steel pipe U is pulled up (directly above the supporting steel pipe M). The main steel pipes on both sides also have the same configuration as the main steel pipe that was first erected, but for the sake of explanation of the construction procedure, a steel pipe pulled up by a center hole jack placed at a high place is hereinafter referred to as a column steel pipe U '.

STEP 7 (see FIGS. 13 to 16)

First, a supporting steel pipe M for supporting the reaction
Is used to connect the supporting steel pipe U ′ to the supporting steel pipe M.
At that time, the reaction force gantry 11 is removed so as not to hinder the connection.

Then, the supporting steel pipe M and the supporting steel pipes U ′, U ′,... Connected thereto are lifted by using the center hole jacks 45 ′ for lifting the main pillar steel pipes on both sides of the bridge girder block lifting device 40. Perform in the same manner as described above. The center hole jack 45 ′ for lifting the steel pipes on both sides may be diverted by moving the center hole jack 45 for the bridge girder block.

Next, extension work of the construction elevator E is performed.

STEP 8 (see FIGS. 17 and 18)

First, when the raising of the main column steel pipe U is completed up to the planned height, the vertical accuracy is confirmed, and the base of the main column steel pipe U and the supporting column steel pipe U 'is fixed by an anchor frame and anchor bolts (not shown) in the caisson C. Is fixed.

Next, concrete is poured into the caisson C (bottom, top).

Next, the support 10 and the reaction force gantry 11 shown in FIGS. 13 and 16 are removed.

Next, concrete is laid stepwise above the caisson C surface by the slip foam method.

Next, the slip form S as the formwork of the tall pier is used as the slip hole lifting center hole jack 4 installed in the bridge girder block lifting device 40.
Using 5 '', the pier body will be lifted and constructed sequentially. The center hole jack 45 '' for lifting the slip form is the bridge hole block center hole jack 4
5 may be used, and the position may be shifted.

Next, the bridge blocks B on both sides of the pier are erected together with the bridge girder block center hole jacks 45 arranged as shown in FIGS. 18, 35 and 36 while constructing the pier frame.

Next, as shown in FIG. 38, the bridge girder block lifting device 40 is separated at the center, and the bridge girder blocks B are efficiently laid in a stable state in both directions efficiently by a balancing erection method.

Since the method for constructing a high-altitude bridge having a steel-pipe / concrete composite high pier according to the embodiment is configured as described above, the following effects can be obtained.

Since the bridge pier is not SRC but a steel pipe / concrete composite structure, the inner formwork can be eliminated. Further, since the bridge girder is lifted by the bridge girder block lifting center hole jack 45 instead of jacking up, a scaffold for lifting the bridge girder can be eliminated. As a result, according to the present invention, labor saving and security are greatly enhanced.

In addition, the construction of the bridge girder can be performed simultaneously on both sides of the pier, so that the construction period can be shortened, and the construction cost can be reduced.

If a center hole jack 45 for lifting a bridge girder block, a center hole jack 45 ″ for lifting a slip form or a center hole jack 45 ′ for lifting steel pipes on both sides of a main column are respectively used, a bridge pier can be constructed. Since a bridge girder can be installed inside, the construction period can be shortened. Furthermore, when the support steel pipes U 'are erected on both sides of the main pillar steel pipe U, simultaneous construction of both support steel pipes is possible, so when pulling up the pier integrally, it is necessary to connect substantially one place. The construction period of the pier can be shortened.

Furthermore, since concrete is cast with the slip form S, the temporary work of forming the form at a high place like the SRC is not required. In addition, since the bridge girder is erected and the main column steel pipe U is raised by remotely operating the center hole jack, there is no danger due to the jack falling over. As a result, according to the present embodiment, safety can be improved.

Further, since the damping steel pipe column 1 is used, the earthquake resistance can be improved.

Further, since the cable 22 is suspended from the lifting means and the lower end of the cable 22 is fixed, the lifting means is operated to extend the cable 22, so that the wind resistance can be improved.

In this embodiment, the present invention is applied to the construction of a tall pier and the construction of a bridge girder. However, the present invention is not limited to this, and can be applied to a bridge pier and a bridge girder suitable for applying the present invention. .

The number, position, shape, and the like of the above-mentioned constituent members are not limited to the above-described embodiment, but can be set to a number, position, shape, and the like suitable for carrying out the present invention.

In each of the drawings, the same components are denoted by the same reference numerals.

[0074]

Since the present invention is configured as described above, the following effects can be obtained.

Since it is not SRC, the formwork is simplified, and as a result, labor can be saved.

Further, since the bridge girder can be erected after the main column steel pipe is erected, the construction period can be shortened.
