Steel sheet row pile embankment-protecting river-dredging method

Abstract

The invention is a piling, reinforcing and dredging method with steel plates, which is to provide a method of dredging river channels with high river water flow, high flow speed and heavy sediment entrained in the river water. Rows of erected steel plates spread over are inserted into both sides of a main river channel; the river water in the main river channel restricted by the steel plates scours and digs the sediment at the bottom of the main river channel, and lead the sediment to the downstream, to lower the bottom layer of the main river channel; when the bottom layer of the main river channel is lowered to below the steel plates, the rows of paved steel plates are continued to be inserted down, so that the river water continues to scour and dig the sediment at the bottom of the main river channel. The procedures are operated repeatedly to gradually lower the bottom layer of the main river channel and expand the capacity of the main river channel. The method can effectively control the river channels with heave sediment in the river water to prevent floods of the river channels, which can ensure the economic development of river shore areas and make sure residents in those areas can live and work in peace and contentment, and has wide promotion and application value.

Description

technical field [0001] The present invention relates to a method of water conservancy dredging and river management, more specifically, steel plates are used as row piles to allow the water to scour and dig out the silt accumulated at the bottom of the main river channel to protect embankments and dredge the river channel, thereby reducing the pressure on the surface of the main river channel. method. Background technique: [0002] Many rivers in the world, due to geographical environment factors, will carry a large amount of sediment in the river water, and the sediment will stay and deposit in the river bed where the river water flows, making the river bed higher and higher. The Yellow River in my country is the river with the most sediment in the world, and it has always been considered a difficult problem in Yellow River governance. For thousands of years, while the Chinese nation has benefited from the nourishment of the Yellow River, it has also suffered from the disa...
