Abstract

The invention relates to the technical field of water conservancy facilities, in particular to a river dam and a dike system. The river dam comprises an interception dam, multiple flow guide supporting pillars and multiple flow guide channels arranged in the interception dam, wherein the flow guide supporting pillars are arranged at the upstream face end of the interception dam and used for dredging sediment deposited at the bottom of a riverbed; the flow guide channels are sequentially arranged along the height direction of the interception dam from top to bottom; the two ends of each flow guide channel communicate with the upstream and the downstream of the interception dam, a cover plate is arranged at one end of at least one flow guide channel, the flow guide channels can be guided or intercepted by the cover plates so that the water level of an upstream watercourse can be adjusted, and thus the technical problems of a large sludge storage quantity and a slow flood discharge speed, existing in the prior art, of the upstream of the river dam are alleviated.

Description

technical field [0001] The invention relates to the technical field of water conservancy facilities, in particular to river dams and embankment systems. Background technique [0002] The barrage is one of the important water conservancy projects in my country, which plays an important role in agricultural irrigation, flood peak regulation, and sediment control. With the sudden increase of flood peak flow caused by extreme rainfall events under global climate change and the new requirements of social development for ecological functions of rivers, the role of barrages has become increasingly prominent. [0003] The main problems of the current sand check dams are: during the flood period, the water volume is large, and the flood water is not released in time. It is easy to be cut off, causing the dam body to move down; due to heavy rain, floods, etc., the river embankment upstream of the barrage burst, a large amount of flood forced the main river channel to divert, and a la...
