Embodiment Construction

[0014] The method for preventing and controlling Yellow River ice flood of the present invention is to develop an artificial river in the upper reaches of the Yellow River ice flood section, the artificial river is located at the lower part of the Yellow River "Ji" shape, and runs through the East and West of the Yellow River; The topography is favorable to the flow direction of the river by using the trend of high in the west and low in the east and high in the north and low in the south; there is a temperature difference between the area where the artificial river flows and the ice flood section, and the temperature in the area where the artificial river flows is higher than that in the ice flood section. The estuary of the artificial river is provided with a dam capable of controlling the water level of the ice flood section, and several sluices are arranged on the dam, and the number of sluices to be opened is determined according to the flow of the river water. The dam is ...

Abstract

The invention discloses a method for preventing and treating yellow river ice flood, which is characterized in that: a artificial stream is channeled on upstream of the yellow river ice flood segment, wherein the artificial stream lies at downstream of JI-segment of yellow river, and communicates east and west of the yellow river; the selection of an initial point at west of the artificial stream and an end point at east is based on topography, and the topography that west and north are high and east and south is low is propitious to water flowing direction; the area that the artificial stream flows across has temperature differential to the ice flood segment, the temperature in area that the artificial stream flows across is higher than that at the ice flood segment, and mouth part of the artificial stream has a dam capable of controlling water level of the ice flood segment. The method of the invention radically resolves a hidden trouble of yellow river ice flood, saves national expenditure, avoids economic loss of the nation and people, the artificial stream has irrigation function in dry season and flood diversion function in flood season, is convenient to transport, and can protects original ecology of ice flood segment of the yellow river by adjusting water level of the ice flood segment by utilizing the water gate.

Description

technical field [0001] The invention relates to a method for controlling rivers in water conservancy projects, in particular to a method for preventing and controlling flooding of the Yellow River. Background technique [0002] Latitude is an important factor affecting temperature. Generally speaking, low latitudes have high temperatures, while high latitudes have low temperatures. The unique "ji"-shaped channel of the main stream of the Yellow River makes it span a large range of latitude, and the temperature difference between the north and the south reaches of the river is obvious, which causes the time of freezing and thawing of the river to be staggered: in places with higher latitudes, the river freezes earlier in winter. The spring thaws late; the river sections at lower latitudes freeze late in winter and thaw early in spring, which is the main reason for the formation of ice floods in the Yellow River. [0003] The danger of the Yellow River ice flood is serious. A...
