Embodiment 1
[0033] see Figure 1-2 , there is a height difference driving platform channel floating connection device on the water, which includes a trestle 1, and an inclined channel pontoon 3 is arranged on the side where the trestle 1 is located. Connected as a whole, a floating bridge 2 is arranged on the side where the boarded pontoon 4 is located. By forming an elevation-adjustable connection device between the trestle 1 and the pontoon 2 with a height difference, the docking connection between different elevations is realized, and the channel of the driving platform with a height difference on the water is guaranteed to be unimpeded.
[0034] Further, the side of the pontoon 4 near the pontoon 2 is hinged with a slat 18 that can adjust its pitch angle through a cable mechanism, and the slab 18 communicates with the pontoon 4 and the pontoon 2 . The angle of the strap 18 can be adjusted through the cable mechanism, thereby ensuring the docking between the strap 18 and the pontoon 2...
Embodiment 2
[0045]The operation method for connecting the trestle bridge to the pontoon bridge by using the floating connection device of the driving platform passageway with a height difference on the water according to any one of the above items includes the following steps:
[0046] Step1: Fabricate and install the floating connection device on the river bank. By tightening the first cable 12, the rotatable part of the main girder 7 of the ramp and the strap 18 are closely attached to the door-shaped column 5. After the whole is launched, use a tugboat to pull the device to the The trestle bridge 1 and the pontoon bridge 2 that have been set up are anchored and positioned;
[0047] Step2: Inject water into the inclined passage pontoon 3 and the board pontoon 4, to ensure that the elevation of the lowest point on the top surface of the floating connection device is the same as that of the bridge deck of the pontoon bridge 2, and that the elevation of the highest point on the top surface ...
