Embodiment Construction

[0030] The steps and working principles of the present invention are further explained below in conjunction with the accompanying drawings and specific implementation examples:

[0031] S1, such as figure 2 As shown, on the left and right sides of the bow of the self-propelled trailing suction dredger 1, a measurement platform 2 that can be automatically lifted is set. A multi-beam transducer 3 is installed inside the platform 2 . The multi-beam transducers 3 on the left and right sides are respectively obliquely installed to form a V-shaped array arrangement.

[0032] S2, such as image 3 As shown, when the self-propelled trailing suction dredger 1 is dredging, the left and right measurement platforms 2 are automatically lowered to the set depth, and the multi-beam measurement system is automatically activated. The effective measurement coverage can reach more than 10 times the water depth.

[0033] S3, such as Figure 4 As shown, the measurement area is divided into mea...

Abstract

The invention provides a dredging-measuring integrated water depth measurement method for a self-propelled trailing suction dredger, which is used to solve the problems of high cost, limited sea conditions, and poor timeliness of data caused by traditional measurement methods. The invention makes full use of the construction characteristics of the self-propelled trailing suction dredger to provide an integrated method of dredging and measuring while dredging construction and measuring, and completes the scanning and surveying of the underwater terrain of the corresponding construction area during the ship construction process, thereby realizing Bathymetry in construction areas. The invention effectively improves the timeliness of measurement before, during and after dredging, and guides the self-propelled trailing suction dredger to sweep shallows in time through real-time measurement, thereby improving the construction efficiency and quality of dredging, and saving the operating cost of measurement work.

Description

technical field [0001] The invention relates to a water depth measurement method, in particular to a dredging-measurement integrated synchronous measurement for a self-propelled trailing suction dredger when dredging a waterway. Background technique [0002] Channel dredging refers to the operation of removing underwater sediment in the channel with dredgers or other tools. Channel dredging is one of the main means to develop channels, increase and maintain channel scale. Water depth is the main technical index of channel dredging construction, and it is also one of the main basis for channel dredging project planning. [0003] The self-propelled trailing suction dredger is a self-propelled, cabin-loaded dredger equipped with a drag head excavator and a hydraulic dredging device. When dredging, lower the rake head to the bottom of the river, use the vacuum effect of the mud pump, suck the mud from the river bottom through the rake head and the suction pipe into the mud tan...
