Embodiment Construction

[0034] The soil type analysis method and control method for dredging by a dredger according to the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, the present invention provides a soil type analysis method for dredging by a dredger, which can use the programmable controller of the dredger to collect dredging data through sensors, calculate soil parameters, calculate the diameter of soil particles, and judge the soil type, specifically including the following step:

[0036] 1) Real-time collection of dredging data of dredgers;

[0037] 2) Calculating the undisturbed settlement velocity of the dredged soil based on the dredging data and the silo model;

[0038] 3) calculating the particle diameter of the soil according to the undisturbed sedimentation velocity;

[0039] 4) Combining the known particle size distribution ranges of different soil types and the particle diameter of the soil to ...

Abstract

The invention discloses a soil type analysis method and control method of dredger dredging. The soil type analysis method comprises the steps that 1, dredging data of a dredger are collected in real time; 2, the undisturbed settlement velocity of dredged soil is calculated according to the dredging data and a mud holder model; 3, the particle diameter of the soil is calculated according to the undisturbed settlement velocity; and 4, in combination with known different soil type grain size distribution ranges and the particle diameter of the soil, the type of the soil is determined. According to the soil type analysis method, the soil type can be determined in real time, the engineering amount caused by offline exploration of the soil type is avoided, then dredging time is shortened, dredging efficiency is improved, and the dredging cost is reduced. According to the control method of dredger dredging, the soil type analysis method is used for analyzing the soil type in real time, relevant control parameters are adjusted in time according to the analyzed soil type, the dredging time is shortened, and the dredging efficiency is improved.

Description

technical field [0001] The invention relates to a soil type analysis method, in particular to a soil type analysis method and a control method for dredging by a dredger. Background technique [0002] With the growing domestic dredging market, dredgers play a huge role in dredging projects such as coastal waterway maintenance, port construction, and land reclamation. Soil is the main object of the dredger. The dredging efficiency of the dredger depends on the settings of control parameters such as the speed of the dredger pump, the speed of the ship, and the angle of the rake head to the ground. These control parameters need to be adjusted according to the type of dredged soil. Adjustment. At present, the dredging operations of dredgers mainly rely on offline analysis data. The way to obtain the soil type is generally: first, before the dredging operation, the dredged soil is obtained through the exploration ship; then, the sample is taken and sent to the laboratory to analy...
