In Fengtai County, the spring rains fell. At the river dredging construction site in the Yangcun town section of the Xifei River, which "diverts the river to the Huaihe River", dozens of workers are braving the rain and taking boats to connect and adjust the silt pipelines and silt curtains on the river to carry out dredging operations.
The silt pipe with the diameter of its mouth like a strong man's waist floated on the river course for hundreds of meters, surrounded by an orange floating ring. They are connected to a dredging boat at one end and thrown in a large cofferdam on the outside of the river embankment. The roar of ships, the sound of running water, and the roar of excavators resounded across the river.
"The dredgers have strong power and large suction. They can wring the river bed and pump the silt and weeds underneath mixed with the river water into the cofferdam thousands of meters away." said the worker who was laying pipelines by the river. "After the muddy water is pumped into the cofferdam, the river flows back to the river course, and the silt remains in the weir, so as to achieve the purpose of rapid silt dredging."
