and arranging a positioning ship below the skylight opening in the channel for positioning the bridge deck transport ship, and transporting the bridge deck to the positioning ship by the bridge deck transport ship.
On the basis of the technical scheme, the method further comprises the following steps: when the bridge deck at the skylight opening needs to be installed, the bridge deck is transported to the lower side of the skylight opening through water, the bridge deck is lifted to the bridge floor through the lifting station and temporarily stored on the bridge deck near the installed bridge deck, the steel beam at the skylight opening is recovered, and the bridge deck at the skylight opening is installed through the bridge floor gantry crane.
On the basis of the technical scheme, when the movable flatcar is arranged on the steel beam, the initial position of the flatcar is positioned near the skylight opening.
Compared with the prior art, the invention has the advantages that:
firstly, arranging a skylight opening on a steel beam outside a channel, arranging a lifting station above the skylight opening, positioning a bridge deck transport ship under the skylight opening, lifting a bridge deck to a bridge floor by the lifting station, transporting the bridge deck to a position near a designed installation position by a flat car, installing the bridge deck to the designed position by using a bridge floor gantry crane, recovering the steel beam at the skylight opening, installing the skylight opening and the bridge deck, reducing the influence of water lifting of the bridge deck on the channel, and improving the lifting efficiency of the bridge deck; especially when the bridge deck is applied to the installation of the bridge deck in the arch lower area of the half-through arch bridge, the spatial interference of the main arch to the hoisting can be avoided, and the hoisting efficiency of the bridge deck is greatly improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1, an embodiment of the present invention provides a method for installing a bridge deck of a cross-channel steel reinforced concrete composite beam, specifically including the following steps:
firstly, a skylight 5 is arranged on a steel beam 6 at the outer side of a channel.
And then a positioning ship 8 is arranged below the skylight opening for positioning the bridge deck transport ship 7, and the bridge deck transport ship 7 is close to the positioning ship 8.
When the movable flat carriage 4 is arranged on the steel beam 6, the initial position of the flat carriage 4 is positioned near the skylight opening 5. When the bridge deck gantry crane 3 is arranged on the steel beam 6, the initial position of the bridge deck gantry crane 3 is located near the designed installation position.
The lower hook of the lifting station 2 is connected with the bridge deck plate 1, and the lifting bridge deck plate 1 is higher than the top surface of the flat car 4.
The flat car 4 runs to the position below the bridge deck 1, and the lifting station 2 lowers the bridge deck 1 onto the flat car 4.
The lifting station 2 is unhooked, the connection with the bridge deck 1 is released, and the platform wagon 4 transports the bridge deck 1 to the vicinity of the design position.
And hoisting the bridge deck 1 to the designed position by the bridge deck gantry crane 3, and circulating the steps until the bridge deck 1 at the position of the remained skylight opening 5 is reached.
When the bridge deck at the skylight opening 5 needs to be installed, the bridge deck 1 at the skylight opening 5 is lifted to the bridge floor, temporarily stored on the installed bridge deck 1, the steel beam 6 at the skylight opening 5 is recovered, and the bridge deck 1 at the skylight opening 5 is installed by using the bridge floor gantry crane 3.
According to the embodiment of the invention, firstly, a skylight opening 5 is arranged on a steel beam 6 on the outer side of a navigation channel, a lifting station 2 is arranged above the skylight opening 5, a bridge deck transport ship 7 is positioned below the skylight opening 5, then the lifting station 2 lifts a bridge deck 1 to a bridge deck, then a flat car 4 transports the bridge deck to the position near a designed installation position, then the bridge deck 1 is installed to the designed position by using a bridge deck gantry crane 3, finally, the steel beam 6 at the skylight opening 5 is recovered, and the bridge deck 1 at the skylight opening 5 is installed. The influence of the hoisting of the bridge deck 1 on the passage of a navigation channel is reduced, the fixed-point hoisting shortens the positioning time of the bridge deck transport ship 7, and the division cooperation of the lifting station 2, the flat car 4 and the bridge deck gantry crane 3 also improves the installation and construction efficiency of the bridge deck 1.
