Description

Gate with function of making an uproar is fallen

Technical Field

The utility model relates to a hydraulic engineering technical field specifically relates to a gate with function of making an uproar is fallen.

Background

The gate is a hydraulic structure built at the sides of river channels, reservoirs and lakes, and has the functions of water retaining and draining. The gate is closed, so that flood blocking, tide blocking and water level raising can be realized, and the requirement of upstream water taking or navigation can be met; the gate is opened, so that flood discharge, waterlogging drainage, sand flushing, water taking or flow regulation according to the downstream water demand can be realized.

In order to form an ornamental landscape on a river channel, landscape gates have been developed in the prior art, wherein the most common type of gate is a bottom-shaft turnover type steel dam gate, and the gate is installed on the river channel, so that the landscape gate has the advantages of good landscape effect, convenience and rapidness in operation (maintenance), flexibility in opening and closing, stepless adjustability of gate opening, convenience in scheduling, hidden opening and closing equipment, no obstacle to landscape, no navigation and the like, cannot cause adverse effects on the landscape of the original river channel, and the time for opening and closing the gate is short, so that timely and effective flood discharge can be ensured during sudden flood.

However, when a landscape gate is built on a river course, a landscape water surface and a landscape waterfall are formed, and meanwhile, due to the water level difference of the upstream and the downstream of the landscape gate (water retaining facilities such as a rubber dam, a steel gate dam, an air shield dam, a flap dam and a concrete overflow dam), great noise pollution is generated during water drainage, and particularly at night, the rest of nearby residents is seriously influenced.

At present, the mode of reducing the noise of the landscape gate is mainly based on the following two ideas, one of which is to reduce the noise by changing the water level difference between the upstream and the downstream of the landscape gate, if the gate is opened and the water is discharged at night, the mode can effectively reduce the noise, but the later stage needs to store water again, and under the condition of less water coming from the upstream, the water needs to spend longer time for storing water, which affects the water landscape effect in the daytime, and meanwhile, the water storage operation also easily causes the cutoff of the downstream river channel and affects the water ecology; and secondly, noise is reduced by improving the flow state of water flow, for example, a certain noise can be reduced by building an overflow dam at the edge of a landscape gate or adding curtain cloth on a landscape waterfall, but the reduction amplitude is limited, and the engineering reconstruction investment is large.

On the premise of not influencing the landscape effect presented by the landscape gate, the method expends the minimum manpower, material resources and financial resources to realize the good noise reduction effect, and becomes a difficult problem which needs to be broken through urgently in the technology.
