Description

Technical Field

[0001] The utility model relates to the technical field of dam desilting, in particular to dam desilting equipment for water conservancy and flood control. Background Art

[0002] Levees play an important role in flood control, but if the river downstream of the levee is seriously silted up, the levee flow will be reduced, and there will even be a risk of dam breach. Desilting can restore the designed hydraulic characteristics of the river, ensure the normal operation of the levee, and improve its flood control capacity. The stability and safety of the levee are closely related to the siltation of the river downstream. River siltation may lead to safety hazards such as water blockage and scouring of the levee foundation. Regular desilting can timely discover and solve these problems and ensure the safe operation of water conservancy projects. The existing desilting method mainly uses excavators or backhoes to excavate and clean up river silt. This is the most common and direct mechanical desilting method, which is suitable for serious siltation. The use of excavators or backhoes is limited by the size and shape of the river. In narrow or tortuous rivers, mechanical operation may be limited, and the silt cannot be completely cleaned up, and other methods need to be taken for supplementary cleaning. In addition, it will also cause damage to the riverbed and its surrounding ecosystems. The weight of the machinery and the vibration during the excavation process may destroy the stability of the riverbed. In view of this, research and improvement are carried out on the existing problems, and a dam silt removal equipment for water conservancy flood control is provided to solve the current problems. The purpose is to solve the problems and improve the practical value through this technology. Utility Model Content
