Abstract
The invention discloses a floating bridge removing method, which comprises the following steps of: 1, removing an old bridge surface; 2, preparing removal construction of a concrete truss of an old bridge; and 3, removing the concrete truss of the old bridge, namely making the bridge overhead through two barges for the first time, fixing a barge on the east side on a river bank on the east side so as to transversely move the old bridge to the upper part of a reinforced concrete foundation on the west side, filling water in a barge on the west side and sinking the barge. After the first movement is finished, the west end of the concrete truss is rolled through a steel roller on the concrete foundation and the east end of the concrete truss is supported by a barge bracket so as to move by hauling the barge until the barge is moved to the river bank, the barge sinks, the concrete truss is pulled to the river bank through a winch, and a crane assists in moving the bridge on the river bank. The method can be used for removing the old bridge, and because the concrete truss is removed by a barge and track combined monolithic translation method, the construction speed is high, navigation closure time is short, and influence of old bridge removal construction on normal operation of a navigation channel is reduced.
