Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and hydropower engineering construction and dam test monitoring, and in particular to an expandable scientific test platform for simulating the entire process of dam construction. Background Art

[0002] The construction of water conservancy and hydropower engineering dams is an important branch of the field of water conservancy engineering. With the continuous development and progress of this field, rich construction experience has been accumulated and many mature technical systems have been formed, providing valuable guidance and reference for the construction of new dam projects. However, due to differences in meteorology, hydrology, materials, dam types and service environments, some water conservancy and hydropower projects face extremely special boundary conditions, and there is even a lack of precedents for reference worldwide. The design, construction and operation of new projects under these complex boundary conditions face a series of new scientific problems and technical difficulties.

[0003] For example, in extremely cold regions, dam construction needs to solve key issues such as temperature control standards and protective measures to ensure the stability and durability of the dam in extremely low temperature environments. In addition, with the development of intelligent technology, the construction standards and control of intelligent dams have also become a new research hotspot. At the same time, optimizing the mix ratio and improving the performance of dam concrete are also important ways to improve the overall quality and safety of the dam.

[0004] In order to solve these problems, it is particularly important to conduct simulation test research and monitoring on the technical problems existing in dam construction. Simulation test can simulate the real environment of dam construction to a certain extent, and provide scientific and reasonable suggestions for engineering design and construction through test data and research results. However, the existing simulation test methods still have shortcomings in some aspects.

[0005] On the one hand, some simulation tests can be carried out in the laboratory, but for some problems involving complex boundary conditions or that need to be combined with specific engineering construction, it is often impossible to construct and simulate the real engineering environment in the laboratory. Therefore, it is necessary to carry out simulation test research on the engineering site to explore in a way that is more in line with the actual engineering. Field tests can fully consider the influence of environmental factors such as large temperature difference, ultra-low temperature, solar radiation, and wind and sand erosion. They have the characteristics of authenticity, timeliness and effectiveness, and are therefore increasingly favored in solving engineering technical problems.

[0006] On the other hand, the existing field simulation test methods also have some limitations. Traditional field tests usually require the construction of single or multiple concrete test models of varying sizes at the project site, the installation of a large number of different types of sensors inside, and the construction of temporary buildings to place monitoring equipment. This method not only requires a large test investment, but also requires the construction of temporary buildings for guarding and data monitoring due to the large volume of the test block, the large number of sensors, and the long test cycle. Therefore, after the test, there is the problem of demolition of the test block and temporary buildings, which increases related costs. If land acquisition costs and construction interference coordination issues are also involved, the test cost and investment will be further increased, the willingness to invest will be reduced, and it is not conducive to the resolution of engineering technical problems.

[0007] In summary, although the existing simulation test methods for dam construction have achieved certain results in solving technical problems under complex boundary conditions, they still have shortcomings such as large test investment and long demolition cycle. Therefore, it is necessary to propose a more efficient, economical and reusable simulation test method to better serve the entire process of dam construction. Based on this demand, the present invention proposes an expandable scientific test platform for simulating the entire process of dam construction, aiming to solve the problems existing in the existing technology and provide more comprehensive and accurate technical support for dam construction. Summary of the invention
