MULTI-LAYER BRIDGE CONSTRUCTION METHOD AND CONSTRUCTION SUPPORTING SYSTEM

摘要

Disclosed are a multi-layer bridge construction method and construction supporting system. The construction method comprises bottom-layer bridge construction and upper-layer bridge construction, and specifically comprises: laying a bottom-layer bridge system on the top of a first jig frame; arranging a second jig frame on an outer side of a supporting bridge system; erecting a conversion device on the tops of the second jig frame and the supporting bridge system; and laying a top-layer bridge system on the top of the conversion device. The supporting system comprises a first jig frame, a second jig frame and a conversion device, wherein the conversion device is erected on the tops of the second jig frame and the supporting bridge system, and is used for supporting a top-layer bridge system. In the multi-layer bridge construction method and construction supporting system in the present invention, a conversion device is provided to support the laying of a top-layer bridge system, and upper-layer bridge construction does not need to rely on the mounting of web members. The present invention has high construction efficiency, can be applied to the construction of various types of bridges, and has a wide application range.
