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 1 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 figure 2 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 image 3 As shown, the measurement area is divided into meas...

Abstract

The invention provides dredging and measuring integrated water depth measuring method for self-propelled trailing suction hopper dredger. The method is used for solving problems of high cost, sea state limitation, and bad data timeliness caused by traditional measuring methods. Construction characteristic of the self-propelled trailing suction hopper dredger are fully used, the dredging and measuring integrated method for dredging construction and measurement is provided, sweeping survey of underwater topography of corresponding construction areas is completed in a ship construction process, and water depth measurement of construction areas can be realized. Timeliness of measuring before dredging, during dredging and after dredging can be effectively improved, real time measuring can be used for guiding timely shallow sport dredging of the self-propelled trailing suction hopper dredger, construction efficiency and quality of dredging are improved, and operation cost of measuring work is saved.

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...
