Description

Technical Field

[0001] The present invention relates to the technical field of river channel dredging, and in particular to a non-secondary pollution dredging construction device and method for river channel ecological environment restoration. Background Art

[0002] Traditional river dredging methods are divided into wet and dry methods. Wet dredging is a method of dredging using large ships and other engineering machinery when there is water in the river; dry dredging is a method of dredging using excavators and other engineering machinery after the river water is pumped out. The wet method is suitable for rivers with large basins and large amounts of water, while the dry method is suitable for rivers with small amounts of water. Therefore, when dredging, it is often necessary to choose different dredging methods based on the actual situation of the river.

[0003] In the existing dredging and dredging construction devices, such as Chinese patent application CN114059608A, the debris in the silt layer can be salvaged by the salvaging component and sent to the debris processing component for debris processing. At the same time, the silt suction component extracts the silt separated from the salvaging component and sends it to the silt processing component for silt processing. In this way, not only the silt in the river channel can be processed, but also the debris in the silt layer can be cleaned up, so that the dredging effect of the river channel is better; by setting the mud leakage hole, the silt adhered to the debris can fall into the mud leakage hole through the discharge pipe, so that the debris and the mud hole are better separated, and the silt is prevented from affecting the treatment process of the debris.
