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 for dredging by a dredger. The soil type analysis method includes: 1) collecting dredging data of the dredger in real time; 2) according to the dredging data and a mud tank model, Calculating the undisturbed sedimentation velocity of the dredged soil; 3) calculating the particle diameter of the soil based on the undisturbed sedimentation velocity; 4) combining the known particle size distribution ranges of different soil types with the particle diameter of the soil , to determine the type of soil. The soil type analysis method can determine the soil type in real time, avoiding the engineering quantity brought by off-line exploration of the soil type, thereby reducing the dredging time, improving the dredging efficiency, and reducing the dredging cost; the dredging dredging control method of the present invention utilizes the The above soil type analysis method analyzes the soil type in real time, and adjusts relevant control parameters in time according to the analyzed soil type, so as to reduce dredging time and improve dredging efficiency.

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...
