A test device for simulating a dike closure hydraulic process and a method

Abstract

The invention provides a test device for simulating a dike closure hydraulic process and a method and belongs to the field of physical model experiments of hydraulics. The test device for simulating a dike closure hydraulic process comprises a testing module, a reservoir capacity change module, a data collecting module and a control module; the testing module consists of all basic testing components; the reservoir capacity change module is externally connected to the testing module; the data collection module is supported by the testing module; the control module is used for controlling a testing process. The method of the test device for simulating a dike closure hydraulic process comprises a device preparation process, a tide level adjusting process, a testing and parameter recording process, a post-testing processing process, a working condition changing testing process, and testing completion and device arrangement. The device has the advantages of simple structure, close connection of components and high testing process efficiency and is widely applicable to many working conditions; the testing design is remarkably superior to the conventional dike closure hydraulic physical model testing design.

Description

technical field [0001] The invention relates to the field of hydraulic model tests of sea reclamation projects, in particular to a test device and method for simulating the hydraulic process of Longkou Helong. Background technique [0002] The sea reclamation project refers to the construction of dikes along the coast to prevent tides and waves, control the water level of the surrounding area and divide the tidal flats and harbor sea areas into land, usually by building seawalls, sluices, ship locks, tidal power stations, pumping stations, fishways and other buildings , and adopt biological measures to make tidal flat areas or harbor sea areas meet the needs of land reclamation, salt production, fresh water storage, aquaculture, industrial land, power generation, transportation, and coastal protection. The seawalls of sea reclamation projects can generally be divided into non-blocking seawalls and blocking section seawalls. The water depth of the blocking section of the seaw...

Problems solved by technology

[0004] Among the published technical schemes, there is still a lack of technical schemes focusing on the design of physical model tests for simulating the hydraulic process of Longkou Helong. Most of the existing physical model test designs for simulating the hydraulic process of Longkou Helong are assembled by temporary components for testing. Design, there are insufficient professionalism in the test process, a large number of instruments required, complex test steps, and a low degree of automation in the test process; at the same time, the Longkou Helong hydraulic process physical model test is used as a teaching experiment, which lacks strong professionalism and obvious demonstration The model test device is not suitable, which leads to problems such as poor visualization effect of teaching experiment and poor teaching effect
