Intelligent multi-stage riverway desilting method

Abstract

The invention discloses an intelligent multi-stage riverway desilting method. The bottom terrain and silt layer thickness distribution information of a riverway is measured through a sonar test set; during sonar detection, sonar detection is carried out at two kinds of different frequencies at the same time, one frequency is matched with detection of a river bottom silt layer, and the other frequency is matched with detection of a riverbed bottom original structure of a non-silt layer. One measured area of the riverway is divided into multiple small areas, a calculation model is set up, and the riverway silt deposition thickness is estimated. Detected large solid garbage is subjected to targeted excavation and clearing though a crane and an excavator of corresponding types. For silt severely afflicted area reach dikes and cutoff riveways tested by a sonar system, riverway river water between dams is exhausted to the rated mixing depth of prepared stirring equipment, and then a high-pressure water gun is adopted for washing away river bottom silt. An amphibious backacting shovel type desilting machine and a chain bucket type bucket-ladder dredger are put into service with targets toachieve desilting step by step. The desilting method is high in desilting efficiency and good in effect.

Description

technical field [0001] The invention belongs to the technical field of river dredging, in particular to an intelligent multi-stage river dredging method. Background technique [0002] River siltation has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. Deeper and wider, the river becomes clearer, and the production conditions and living environment of the masses have been significantly improved, achieving the goal of "clear water, smooth river, green banks and beautiful scenery". Siltation in small and medium-sized rivers is relatively common in my country, and the original ability of rivers to regulate and store floods and prevent and mitigate disasters has been weakened. In recent years, the state has strengthened the management of small and medium-sized rivers and rural rivers. The existing river channel dredging method usually simply blows and stirs the silt deposited on the bott...

Problems solved by technology

The existing river channel dredging method usually simply blows and stirs the silt deposited on the bottom of the river into turbid water through mechanical equipment, and flows away with the river, thus playing a role in dredging. However, these commonly used methods have great limitations when dredging rivers, low dredging efficiency, high degree of manual intervention, and unsatisfactory dredging effects
