Problems solved by technology

During this process, since the river channel 3 has been dredged, if the water level rises slightly, the water flow will overflow from the river channel 3 to the river beach 2 and affect the construction equipment located on the river beach 2, causing safety hazards. ACCIDENT

Embodiment Construction

[0025] Please refer to Figure 1 to Figure 4 , taking the common river to be dredged in the prior art as an example, projected along the direction of water flow, in the cross-section of the river, the river is located between the two banks 1, including the river beach 2 formed at the bottom of the river, and the river beach 2 between the two river beaches. The river channel 3 used for the passage of water, the sediment 4 accumulated on the river bank 2 and the river channel 3, the slope 5 connected between the river bank 2 and the bank 1, and the river bed at the bottom of the channel 6, the river channel dredging method of the present invention comprises the following steps:

[0026] Step S10: Excavating the sediment 4 above the river beach 2 and the river channel 3 from top to bottom to form a stepped construction platform, the bottom of which is flush with the top of the river beach 2 . It includes the following steps:

[0027] Step S11: along the direction of water flow,...

Abstract

The invention discloses a riverway dredging method. The riverway dredging method comprises the following steps that a riverway is excavated from top to bottom to form a step-shaped construction platform; pre-dredging construction is conducted on the construction platform, channel pulling construction is conducted on a channel of the riverway, and the channel is dug to a riverbed of the riverway. Compared with the prior art, the riverway dredging method has the advantages that potential safety hazards caused by the fact that the height of a side slope is too high can be reduced, damage to construction equipment due to water level changes is reduced, and safety is high.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a river channel dredging method. Background technique [0002] my country's landforms are complex, with rivers of all sizes spreading all over the country. As the seasons change, rivers generally have dry seasons with low water levels and flood seasons with abundant water flows. On the other hand, under the erosion of water flow, the soil in the river channel will loosen and accumulate in certain places. If it is not cleaned up, it will cause blockage of the river and even cause flooding. Therefore, river dredging projects have been related to the national economy and people's livelihood since ancient times. In ancient times, dredging was mainly done by manpower through hand tools. With the development of industry, mechanical engineering equipment such as excavators and trucks appeared to assist in the completion of dredging works. [0003] For the basi...
