Embodiment Construction

[0022] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention but not to limit the scope of the present invention.

[0023] The present invention is described as a specific embodiment below with the Huaihe River entering the river channel (middle and lower section) river engineering model:

[0024] (1) Site layout

[0025] According to the existing data and test requirements, the scope of the model is from Gaoyou Lake in the middle and lower section of the Huaihe River to the control line of the Guijiang River, with a total length of about 100km. The water inlet tank simulates Gaoyou Lake, and the outlet tank simulates the Yangtze River. (Middle and lower section) Width between the tops of embankments on both sides facing the water.

[0026] The layout of the model site comprehensively conside...

Abstract

The invention discloses a manufacturing method of a river model. The manufacturing method comprises the steps of 1, simulation area selecting; 2, manufacturing material selecting; 3, model manufacturing site selecting; 4, model manufacturing; and 5, roughening. The river model manufactured through the manufacturing method can truly simulate a real river and facilitates scientific research.

Description

technical field [0001] The invention relates to a method for making a river engineering model, which belongs to the technical field of river engineering model tests. Background technique [0002] Due to the extremely complicated process of river channel deformation under natural conditions and after construction projects, it is often difficult to directly solve many problems of river bed deformation and channel regulation by analytical research and calculation methods, but it is possible to solve them directly and conveniently by using model tests. . River engineering model test is one of the important means to study river flow and river bed deformation. The river engineering model test is to use the knowledge of river dynamics, according to the similar principle of water flow and sediment movement mechanics, to simulate the boundary conditions and dynamic conditions similar to the prototype, to study the flow of rivers in the case of natural rivers or in the case of hydrau...
