EXISTING SUPERSTRUCTURE REBUILDING METHOD
To provide an existing superstructure rebuilding method whose object is to solve the problem of the prior art that is the issue of the invention of the present application, i.e., the object is to suppress the impact on the current traffic, and to secure the current traffic even during the period when the superstructure of a live-line bridge is removed.SOLUTION: An existing superstructure rebuilding method of the invention of the present application is a method for rebuilding the existing superstructure in the target section of an existing bridge, comprising a temporary substructure construction step, a new superstructure construction step, a temporary road opening step, an existing superstructure removal step, a temporary road closing step, a new superstructure installation step, an existing bridge opening step, and a temporary structure removal step. Of these, in the temporary road opening step, the traffic on a target section of the existing bridge will be closed, and a temporary road will be formed through the new superstructure to open the traffic on this temporary road.SELECTED DRAWING: Figure 6
【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち、現況の交通に与える影響を抑制することを目的とし、活線橋の上部工を撤去する期間も現況の交通を確保することができる既設上部工架け替え方法を提供することにある。【解決手段】本願発明の既設上部工架け替え方法は、既設橋の対象区間で既設上部工を架け替える方法であって、暫定下部工構築工程と新設上部工構築工程、仮設道路開放工程、既設上部工撤去工程、仮設道路閉鎖工程、新設上部工設置工程、既設橋開放工程、暫定構造撤去工程を備えた方法である。このうち仮設道路開放工程では、既設橋における対象区間の交通を閉鎖するとともに、新設上部工を通る仮設道路を形成してこの仮設道路の交通を開放する。【選択図】図６
