Description

Novel gravity type transverse moving tidal gate structure

Technical Field

Background

The tidal gate is a water gate which is built near a coastal area or a river mouth and is used for blocking tide, storing fresh water, discharging flood and draining stagnant water. And when the tide rises, the gate is closed, so that the tide water is prevented from flowing backward into the river channel, the fresh water in the inland river is blocked, and the requirements of water diversion, shipping and the like are met. When the tide is removed, the tide level is lower than the river level, and the gate is opened, so that flood discharge, waterlogging drainage and silt flushing can be realized.

China as a coastal country has a large number of rivers entering the sea, and both banks of the rivers are basically important cities and regional low-lying places. With the continuous rising of global sea level and the continuous aggravation of ground subsidence, the invasion of storm surge seriously affects the life and property safety of people in the peripheral area of a river channel, so that the construction of a tidal barrier at a sea estuary is urgently needed.

The transverse sliding door is one of the common tidal gate types, has the advantages of bidirectional water retaining, no obstruction to navigation, good overhauling conditions and the like, is suitable for opening and closing in still water, and is supported by the gate piers on two sides under stress during water retaining, but the span of the gate is limited. At present, in hydraulic engineering built at home and abroad, the span of a transverse sliding door is not more than 50m and is smaller, the section of a door body of the transverse sliding door is a closed rectangle generally, the structural strength is poorer, and the landscape effect is general.

2. After the section of the gate body of the gate is improved, the integral stress mode of the sliding door is correspondingly adjusted, the stress support of the gate body during water retaining of the traditional sliding door depends on gate piers on two sides to form the stress mode of a simply supported beam, and the gate span is limited by the stress mode and is not suitable to be overlarge; in addition, the cross section of the triangular door body is not suitable for bearing large bending moment, and the horizontally-sliding door is designed into a gravity type in order to meet the requirement of large-span moisture resistance.

4. Because the process that the tidal barrier moves from the gate warehouse to the river channel central water retaining generally needs 1-2 hours, and the process rises along with the tide water at the open sea side in the period, if a closed door body structure is adopted, a certain water head difference is generated at the upstream and downstream of the tidal barrier, which is not beneficial to the stable operation of the gate (because the buoyancy balances most gravity and the weight of the gate is lighter), the invention arranges overflowing channels at most door bodies (except the door bodies provided with the buoyancy tanks, the overflowing channels are arranged), thereby ensuring the overflowing capacity of the river channel and avoiding the overlarge water head difference generated at two sides of the gate.

5. The invention integrates the structure of the building and the traditional hydraulic gate, endows the gate with more building space and functions, has simple structure and reasonable stress, and shows the structure beauty in the building art.
