A River Flood Control Structure

Abstract

The invention belongs to the technical field of river flood-fighting control tools, and particularly relates to a river flood-fighting control structure. The river flood-fighting control structure comprises a dam body, wherein the dam body consists of a plurality of flow division passages; a plurality of partition plates are arranged in the flow division passages; the flow division passages are divided into a plurality of tributary passages by the partition plates; a plurality of nicks are formed in the sidewalls of the tributary passages; the nicks in the same tributary passage are distributed to form a horizontal line; the nicks in different tributary passages are distributed to form oblique lines; the horizontal lines form included angles of 15 to 60 degrees with the oblique lines; through holes penetrating through the adjacent tributary passages are formed in the partition plates. The river flood-fighting control structure has the beneficial effects that silt and foreign materials can be well cleaned, larger foreign materials can be removed, and the river flood-fighting control structure is difficult to block.

Description

Technical field [0001] The invention belongs to the technical field of river flood control appliances, and in particular relates to a river flood control structure. Background technique [0002] At present, during the rainy season in China, floods occur in the Yangtze River Basin, Heilongjiang River Basin and Songhua River Basin due to heavy rainfall. At present, the main methods of flood control are: 1. Relying on blockage, using mud and rock and other blockages to block the flooding opening of the dam, thus playing a certain role, but this kind of method is often not effective, and sometimes leads to greater The problem. The second is to divert the dams in the flood-hazard areas by sorting out the diversion, thereby reducing the water flow and achieving the goal. This kind of method can play a better role, but when a flood occurs, it is often accompanied by a large amount of silt or other debris, so it will block the comb flow channel, thereby reducing the effect. Moreover, ...

Problems solved by technology

This kind of method can play a better role, but when a flood occurs, it is often accompanied by a large amount of silt or other debris, so it will block the combing channel, thereby reducing the effect

Moreover, when the water flow is large, the dam will have limited drainage and there will be no time for drainage, which will put pressure on the dam.
