Sand suction method

Abstract

The invention relates to the technical field of riverway regulation, in particular to a sand suction method. A building body is included, a bearing ship and sand suction equipment are included, the sand suction equipment comprises a separation cover immersed in a riverway water body, a scouring water guide assembly and a sand discharge pipe, the sand discharge pipe is arranged on the bearing ship in a liftable mode and communicates with the top of the separation cover, so that the separation cover can be inserted into silt at the bottom of a riverway, the end, away from the separation cover, of the sand discharge pipe communicates with a sand pump preset on the bearing ship, the scouring water guiding assembly is installed in the sand discharge pipe, and one end of the scouring water guiding assembly penetrates and is exposed out of the top of the sand discharge pipe and communicates with a water supply pump preset on the bearing ship, and the other end of the scouring water guiding assembly extends into the separation cover and is used for washing silt in the separation cover. According to the method, the influence on the ecological environment in the cleaning process can be reduced.

Description

technical field [0001] The application relates to the technical field of river regulation, in particular to a method for absorbing sand. Background technique [0002] In recent years, due to severe deforestation of trees, surface vegetation has decreased, soil erosion has been serious, and the lost water and soil have accumulated at the bottom of the river, resulting in a sharp decline in the drainage capacity of the river. In order to improve the drainage capacity of the river, it is necessary to regularly clean up the sediment accumulated at the bottom of the river. [0003] In the traditional cleaning method, the carrying ship carries the excavator to move to the designated location where the sediment needs to be cleaned. The boom of the excavator penetrates into the river bottom, and the bucket of the excavator digs up the sediment at the bottom of the river. Carry the inside of the ship to clean up the sediment accumulated on the bottom of the river. [0004] However,...

Problems solved by technology

[0004] However, when the bucket of the excavator excavates the sediment, part of the sediment will be remixed into the water body of the river channel, causing the water body of the river channel to become turbid, which will affect the growth of some fish, which is not conducive to the ecological environment construction; therefore, there is room for improvement
