Embodiment Construction
[0033] The steps and working principles of the present invention are further explained below in conjunction with the accompanying drawings and specific implementation examples:
[0034] S1, such as figure 2 As shown, a lifting platform structure well is arranged in the midship of the front part of the grab rotary mechanism of grab dredger 1, and a set of automatic lifting and measuring mechanism is installed in the measuring structure well, which consists of lifting platform, lifting servo mechanism, internal rotation mechanism , platform automatic locking device, etc., and the multi-beam measuring device 2 is installed on the measuring mechanism.
[0035] S2. When the measurement mode is turned on, the automatic lifting mechanism controls the multi-beam measurement device 2 to extend out of the bottom plate of the ship and lower it to the set depth underwater to ensure that the multi-beam measurement device 2 is in a suitable measurement position and forms a fixed angle with...

The invention provides a dredging and measuring integrated sounding survey method for a grab dredger, which is used for solving problems of sea state restriction, poor timeliness of measured data andhigh cost brought by the traditional measurement method. A dredging and measuring integrated method for alternatively performing dredging construction and sounding survey is provided by fully utilizing construction characteristics of the grab dredger. Sweeping survey of underwater topography in corresponding construction areas is completed in ship grab construction and dumping clearances, so thatsounding survey of the construction areas is realized. The survey operation can be performed under construction conditions of the grab dredger, the measurement accuracy and coverage area meet construction surveying requirements, and synchronous measurement in the construction process is realized. Measurement in the construction area is gridded, the grid data is subjected to multidimensional storage, and the multidimensional data is processed by adopting an artificial intelligence algorithm so as to obtain measured data in the construction area before dredging, during dredging and after dredging. Therefore, the dredging construction efficiency and quality are improved, and the operating cost of the measurement operation is saved. The ship body structure and construction method of a dipper dredger are similar to those of the grab dredger, so that the dredging and measuring integrated sounding survey method disclosed by the invention can be applied to the dipper dredger.
Description
technical field [0001] The invention relates to a water depth measurement method, in particular to the dredging-measurement integrated synchronous measurement used for dredging construction of a channel by a grab dredger. 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] A grab dredger is a channel dredging construction vessel with a grab. When dredging, the grab dredger uses the grab on the steel cable, relies on its gravity, puts it into the water to a certain depth, digs and grabs the sediment by inserting the mud layer and closing the grab, and then controls the dredging by manipulating the ship. The crane mechanicall...
