The measuring device comprises a planar board for bearing a measurement model of the artificial fish reef, wherein the fixed end of the planar board is provided with an angle measuring apparatus; the planar board can rotate around a measurement center of the angle measuring apparatus; the upper surface of the planar board is provided with a sediment grain layer; an equal proportion miniature of the artificial fish reef to be measured is placed on the sediment grain layer; and the lower part ofthe rotating end of the planar board is supported by a dynamic pressure jack. The device and the method for measuring the maximum static friction coefficient of the artificial fish reef have the advantages of improving the accuracy of measuring technical parameters of the artificial fish reef, shortening the production cycle of manufacturing the artificial fish reef, and reducing the production cost of the artificial fish reef.

Description

technical field [0001] The invention relates to measurement technology, in particular to a technology for measuring a device and a method for measuring the maximum static friction coefficient between an artificial fish reef body and a seabed surface. Background technique [0002] Artificial reefs are artificial structures placed in the sea to improve the ecological environment of sea areas and increase fishery resources. So far, the research and construction of artificial reefs has a history of nearly 30 years in our country, and it has played a good role in the restoration of offshore ecological environment and the proliferation of fishery resources. However, most of my country's artificial reef construction is still at the level of imitating foreign experience or directly applying foreign research results, and there is still a lack of effective support for key technologies, such as reef anti-slip, anti-overturning, and anti-subsidence corresponding to the characteristics o...

Problems solved by technology

If the method of seabed actual measurement is adopted, it is necessary to pour the designed artificial reef in advance and put it into the corresponding sea area, and then conduct seabed observation, which is time-consuming and laborious due to the constraints of production cost and production cycle

Moreover, due to the complexity of the seabed and the heavy weight of the artificial reef, the feasibility of the seabed measurement method is poor.

In the past, after the corresponding stability check before launching, because there is no relevant measured data support, the selection of the maximum static friction coefficient of the seabed is mostly based on empirical values ​​and only based on simple calculations based on empirical formulas, which brings great errors to the calculation of stability checks. , it is difficult to predict the stability performance of the reef. If the stability of the artificial reef cannot be guaranteed, the function of the artificial reef will be seriously affected, and it will also bring great losses to the construction of the artificial reef.
