Title:
X-ARCH BRIDGE CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/115812
Kind Code:
A1
Abstract:
An X-arch bridge construction method, comprising: using a gantry crane (1) to erect a calibrated part of a main bridge; and using a bridge deck crane (2) to erect a main arch on a bridge deck of the erected main bridge, and using the gantry crane (1) to continue erecting other parts of the main bridge. The construction method fully utilizes a working plane and a working space; and when the designed vector height of the existing X-arch bridge is higher and higher, the bridge deck crane (2) is used to erect the main arch, the erection requirement does not need to be met by increasing the height of the gantry crane (1), the gantry crane (1) does not need to be used to erect relatively high arch ribs of the main arch, and the demand height of the gantry crane (1) can be reduced to a certain extent. Moreover, the construction method can synchronously assemble the main arch and a steel girder of the main bridge, thereby shortening the construction period and achieving high construction efficiency and high practicability.
