Method for improving " (application number：2013104189200, publication date：2015.3.25) and Chinese invention patent application " it is a kind of it is light-duty,
Have the function of from it is floating and can the elevated structure that sets up of manpower " (application number：2014102604383, publication date：2014.9.10) carry
Gone out it is a kind of first set up the bridge that swims, after be promoted to the technical thought of overhead trestle.But after coast-floating stage is promoted to overhead trestle, packet
It includes trestle dead weight and bridge floor load is undertaken in interior whole load by supporting leg, it is high to the force request of supporting leg, cause overhead trestle
Logical loading capability it is relatively limited, coast-floating stage is not achieved and is formed by logical loading capability by buoyancy.
In short, problem of the existing technology is：Coast-floating stage resists vertical bending moment and antitorque ability is weak, it is difficult in
It survives and uses under the conditions of wave.
Invention content
The purpose of the present invention is to provide a plants case purlin combined type coast-floating stages, resist vertical bending moment and antitorque ability
