Hydraulically automatic lifting flood prevention walls and automatic lifting method

Abstract

The invention relates to hydraulically automatic lifting flood prevention walls which are arranged along the inner side of a river levee in a paralleling manner. Each hydraulically automatic lifting flood prevention wall comprises a driving device, locking mechanisms, vertical columns, a base and a baffle, wherein the base is a hollow cavity; the baffle is assembled in the inner cavity of the base through the vertical columns in the vertical direction; sliding chutes corresponding to the baffle are formed in the side parts of the vertical columns; the driving device corresponding to the baffle is arranged in the inner cavity of the base, and comprises a waterwheel and a pulley group; the waterwheel drives the baffle to move up and down through the pulley group along the sliding chutes; by the arrangement of the lifting baffle, the baffle is hidden in the base of each flood prevention wall in the non-flood season; when flood occurs and reaches a specific water level, the flood prevention baffle automatically rises up under the action of the traction force of the waterwheel; after the baffle rises up and reaches the upper parts of the vertical columns, bayonets at the top of the baffle are connected to the locking mechanisms on the vertical columns, to form a fixed connection relation; and the baffle is used for blocking the flood, to complete the flood prevention task.

Description

technical field [0001] The invention belongs to the field of urban flood control, and in particular relates to an automatic lifting flood control wall that takes into account both urban flood control and urban landscape. Background technique [0002] At present, river embankments in cities are effective channels to avoid flood disasters, and can release floods in summer, effectively protecting the safety of cities in the river basin. In order to control the destructive effect of the peak water flow of the river on the hinterland of the river channel, parallel flood embankments or flood walls are often built along both sides of the river channel to avoid possible damage caused by floods, such as floods that will cause changes in the ecological environment in the watershed, It causes changes in the river course, soil erosion and barren land, etc., and even washes away and destroys the vegetation and buildings on the river bank, which poses a huge threat to people. Therefore, ...

Problems solved by technology

However, the application of these new technologies and concepts has not fundamentally changed the barrier characteristics of the dam; nor has it truly released the landscape value of the river water surface in its urban hinterland development zone

Generally speaking, the elevation of the top of the embankment will be at least 4 meters higher than that of the development plot, and the first or even second floors of the buildings adjacent to the river bank cannot see the water surface at all, but "nest" in the shadow of the river bottom; at the same time, The bottom two floors of the building are probably used for commercial development, which greatly reduces the value and charm of waterfront buildings

Moreover, it is not easy to form a high-energy, high-value waterfront space to accommodate public activities
