Problems solved by technology

[0004] At present, the laboratory of the School of Surveying and Mapping Engineering of Huaihai Institute of Technology has a SES-2000 acoustic parametric array series shallow stratum profiler produced by Innomar, Germany. In the parts recognition, indoor training, ship installation and design, sea practice, data post-processing and other links, the indoor training link is very difficult. Due to the lack of an intuitive test operation platform, it is difficult for students to intuitively grasp; in addition, due to the lack of columnar sample and auxiliary survey equipment such as drilling and coring, resulting in great difficulties in later stratigraphic interpretation

Embodiment 1

[0029] Embodiment 1, with reference to figure 1 , an indoor test device used in conjunction with a shallow formation profiler:

[0030]The device includes a three-dimensional test platform 2 and several deposit templates 11 with different thicknesses and replacements; waterproof and noise reduction treatment is done around the inside of the three-dimensional test platform 2; simultaneously, a group of several sediment templates 11 are arranged on the three-dimensional test platform 2, from bottom to top according to the particle size of the sediment template 11 from large to small, the thickness of each sediment template 11 is not less than 5cm, and the total thickness of the sediment template 11 is 50-150cm;

[0031] The device is also equipped with a water injection and drainage system. Before the test, water is injected into the three-dimensional test platform 2, and the height of the injected water body is greater than the total thickness of the sediment template 11.

Embodiment 2

[0032] Embodiment 2, in the indoor test device described in Embodiment 1 that is used in conjunction with the shallow formation profiler: the sediment template 11 is classified into gravel sand boards and coarse sand boards according to the particle size of the raw materials from large to small , fine sand board and clay board, each group of sediment template 11 is provided with at least 2 kinds of sediment template 11; Or, described sediment template 11 is divided into according to Sheppard's triangle sediment classification method: sand board, silt There are 10 types of sand boards, sandy silt boards, silt boards, clay silt boards, silty clay boards, clay boards, sandy clay boards, clay sand boards, and sand-silt-clay boards , each group of sediment templates 11 is provided with at least two kinds of sediment templates 11 .

Embodiment 3

[0033] Embodiment 3, in a kind of indoor test device described in embodiment 1 or 2 and supporting the use of the shallow formation profiler: the described waterproof treatment adopts cement-based permeable crystalline waterproof coating, and carries out according to the following method: first put The concrete base surface to be waterproofed shall be treated with water absorption. After fully absorbing water to saturation without water accumulation, the cement-based permeable crystalline waterproof coating shall be applied to the concrete base surface by rolling brush or batch scraping. Construction The thickness is above 1.5mm; after construction, spray water on the surface of the waterproof layer 1-2 times a day for at least one week.

Abstract

The invention provides an indoor test equipment used in match with a sub-bottom profiler, comprising a three-dimensional test platform and a plurality of sediment templates with different thicknesses and replaced in use, wherein waterproof and noise elimination treatment is made around the inner side of the three-dimensional test platform; meanwhile, a group of plurality of sediment templates are arranged at the bottom of the three-dimensional test platform, the sediment templates are placed in sequence from bottom to top, namely the particle sizes of the raw materials of the sediment templates are from large to small, the thickness of each sediment template is no less than 5cm, and the total thickness of the sediment template is 50-150cm. The equipment is also provided with a water injection and drainage system, wherein before test, water is injected into the three-dimensional test platform, and the height of the injected water body is greater than the total thickness of the sediment template. The equipment in the invention is simple and reasonable in design, and convenient to use, various types of bottom sediments can be simulated through setting, and the acoustic parameters and image texture features of various bottom sediments can be obtained by remote measuring of the sub-bottom profiler, thereby providing accurate sample parameters for acoustic classification of bottom sediments and being applicable to teaching.

Description

technical field [0001] The invention relates to an indoor seabed observation test device, in particular to an indoor test device matched with a shallow formation profiler. Background technique [0002] With the large-scale development of marine resource development activities, substrate classification and identification are important contents of marine scientific investigation and research. The traditional and conventional seabed bottom detection method is to obtain samples based on station-type mechanical means, and determine the type and distribution characteristics of seabed sediments through laboratory sample analysis. Deep water areas are more difficult. At the same time, this sampling method generally uses fixed-point discrete sampling according to a certain grid, and divides the sediment types in the survey area through interpolation and extension, so its representativeness will be affected to a certain extent. [0003] Acoustic method remote measurement of acoustic...
