Description
Technical Field
The utility model relates to a water conservancy project of infrastructure construction especially relates to a lower string bridge crossing device of river channel midspan.
Background
The Jinghang Dazhang canal is the ancient canal with the longest mileage and the largest project in the world, is one of the oldest canals, is called three great projects of China ancient times together with the great wall and the Karl well, and is a great project created by ancient workers in China. The great canal has a length of about 1797 km from south to Tsingtah (Jinhang state), and from north to drop of water county (Jinbeijing), which passes through the five water systems of Jinzhejiang, Jiangsu, Shandong, Hebei province, Tianjin and Beijing, and runs through the five water systems of the sea river, the yellow river, the Huaihe river, the Yangtze river and the Qiantanjiang river. The Jinghang Dazhu canal is used up to now, plays a great role in the development and communication of economy and culture among the south and north areas of China, particularly in the development of industrial and agricultural economy in areas along the line, and more importantly, becomes one of the signs of the Chinese cultural status.
The Jinghang Dazhang river starts to be built in spring and autumn, is later rebuilt towards the past through the courses of inertia, Tang, Yuan, Ming and Qing, is successively applied to the fields of military affairs, politics, economy and the like, and obtains brilliant achievement. In 1855 the yellow river was diverted, and due to the lack of main water source, the river channels in some areas of the canal were dry, and the great canal in Jinghang lost its original brightness, and some sections of the canal had stopped navigation. At present, the whole-line re-voyage of the Jinghang big canal is increasingly louder, and the national people are keenly expecting the engineering to be implemented early so as to realize the great revival of the canal culture.
The crossing problem of the Jinghang big canal and the yellow river is one of the difficulties of the whole-line re-voyage of the canal. The crossing problem of the Jinghang big canal and the yellow river is conventionally solved in three ways, namely: and (4) level crossing, tunnel underpass and aqueduct overpass. The level crossing mode needs to break the dike of the yellow river to organically connect the canal and the yellow river channel. The yellow river water sand condition is extremely complex, the channel is greatly influenced by the river channel erosion and deposition change, the navigation can only be realized in partial seasons and partial time periods by limiting the water inflow of the yellow river, and the provided traffic flow is greatly limited. In addition, the flat crossing mode has a large influence on the river situation, and the large influence on the flood prevention and river transition safety of the yellow river is certainly brought. Therefore, the arrangement of the parallel-crossing mode is very complicated, and the influence factors on normal navigation are excessive. In the tunnel mode of wearing down, according to the requirement of going the ship in the tunnel, the hole diameter needs about 20m, and in order to guarantee tunnel structure safety, the tunnel should be enough buried depth, no matter take open cut construction, still shield structure construction method, the technical challenge is very big, and uncertain factor is more. The aqueduct upper-span scheme is technically feasible and has similar experience, but because the whole line in the aqueduct is filled with water, the aqueduct structure is too large in size and high in manufacturing cost due to the high-level channel of a large canal and the large tonnage of a ship.
