Embodiment Construction
[0028] The present invention will be described in more detail below in conjunction with the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0029] The method of crossing the river (such as the Yellow River) crossing the waterway when the waterway is running in the present invention requires the use of a special ferry device:
[0030] The bridge crossing device used in the present invention adopts double lines (two bridge crossing devices with the same structure) to be arranged in parallel, and is connected by transfer platforms at both ends, so as to realize the circular transportation of ferry boats on two routes. Certainly, according to the concrete situation of actual shipping, also can only adopt the single-line ferry device to carry out the work of transporting the ferry.
[0031] The specific structure of each route (bridge crossing device) is as follows: Figure 1~5 As shown, all include the ship lift 1 that is respectively a...

The invention discloses an underhanging bridge crossing method for crossing a river intersecting with the waterway when the waterway is in operation. When the ferry boat navigating along the canal reaches the position where the river crosses the waterway, the ferryboat is first guided into the ship receiving compartment, and the crane drives the boat to be lifted. The pallet, the ship-carrying box, and the ferry go up. After the rigid hanger on the top of the ship-carrying box is flush with the lifting point of the mobile trolley, the rigid hanger is fixed, and the mobile trolley will tow the ship-carrying box to the opposite bank of the river. The ship lift on the opposite bank will The lifting pallet is hoisted, the mobile trolley transports the ship-bearing box to the boat-lifting pallet, connects the ship lift on the other side of the river to lift the pull rope, removes the mobile trolley and connects the rigid hanger of the boat-bearing box, and then lifts the ship through the crane The supporting plate, the ship-holding box and the ferry boat are lowered, and after being lowered to the water surface elevation in the target river, the ferry boat can be guided out of the ship-holding box to continue sailing. The method of the invention is easy to implement and is less affected by changes in the erosion and siltation of the Yellow River channel; the double-line arrangement can realize the circular transfer of the fleet, and the cost is low, and the operation and maintenance are also relatively convenient.
Description
technical field [0001] The invention relates to a waterway infrastructure construction project, in particular to an underhanging bridge crossing method for crossing a river intersecting a waterway when the waterway is in operation. Background technique [0002] The Beijing-Hangzhou Grand Canal is the ancient canal with the longest mileage and the largest project in the world, and also one of the oldest canals. Together with the Great Wall and Karez, it is called the three great projects of ancient China. It is a great project created by the working people in ancient China . The Grand Canal starts from Yuhang (now Hangzhou) in the south, ends in Zhuojun (now Beijing) in the north, passes through the four provinces of Zhejiang, Jiangsu, Shandong, and Hebei, and the two cities of Tianjin and Beijing, and runs through the five major water systems of the Haihe River, the Yellow River, the Huaihe River, the Yangtze River, and the Qiantang River. , with a total length of about 179...
