Intensive type flood irrigation channel

Abstract

The invention belongs to the technical field of farmland water conservancy, and particularly relates to an intensive type flood irrigation channel. The problem that flood is difficult to utilize and is harm is solved. The channel comprises an inner limiting dam wall and an outer limiting dam wall which are arranged in parallel; and a channel is formed between the inner limiting dam wall and the outer limiting dam wall; elevation of the channel is lower than the lowest water level of a riverbed of a section; an outer limiting dam wall water-limiting edge pier is arranged at a downstream end ofthe outer limiting dam wall, and a desilting draining opening channel is formed in the outer dam limiting wall water-limiting edge pier; the outer dam limiting wall water-limiting edge pier is provided with an overflow cutting surface apron; the outer side of the desilting draining opening channel is provided with a desilting drainage opening channel gravity apron; a channel brake pad is arrangedat the downstream part of the desilting draining opening channel; a water supply opening channel is formed in the inner limiting dam wall at the downstream side of the channel brake pad; the inner side of the water supply opening channel is provided with a water supply opening channel traction type apron; a water outlet channel is formed in the downstream side of the water supply opening channel,and a left pull gate plate and a right pull gate plate are arranged at the water outlet opening channel. According to the invention, the water is directly taken out of the longitudinal channel, so that a fixed rolling dam is omitted, and river channel safe flooding is not influenced.

Description

technical field [0001] The invention belongs to the technical field of farmland water conservancy, in particular to an intensive flood irrigation channel. Background technique [0002] Since the invention of cement, there has been a development in promoting the construction of the river rolling dam hub project, which has solved the problem of stable supporting water intake for flood silting and farmland irrigation. However, due to the influence of river bends and tributary confluence in hilly areas, the unit area of ​​available land on both sides of the river is cut into small pieces, and each piece of land on both sides of the river can achieve the purpose of silting, irrigation and water supply. The short-distance or intensive construction of horizontal rolling dams in the river channel is not only financially unbearable, but also in the event of a catastrophic flood, the entire line is bound to flood into the river channel water level, endangering the safety of the river ...
