Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] The specific embodiment of the present invention provides a method for making broken panels for river engineering model tests, such as image 3 Shown, including:

[0026] Step 1. Draw the curve script.

[0027] Specifically, collect data from a predetermined cross-sectional shape and draw it into a script including seventeen columns and several rows (generally greater than forty rows), such as Figure 4 As shown, column A is the section number, column B is the st...

Abstract

The invention provides a method for making section boards in river model tests. The method comprises the steps as follows: drawing curve scripts; drawing the scripts by control points; marking the scripts by texts; running the scripts in an AutoCAD (Auto Computer Aided Design); drawing a plurality of the section boards and adjusting the positions; and making the section boards. According to the invention, the predetermined section shapes are recorded in a text form and drawn in a script form in the AutoCAD, so that the method can be very easily mastered by general engineering technicians without complex programming; the practical situations of general drawing printers and mould-making veneers are fully considered in the process of drawing the section boards, so that the method is stronger in practicality and lower in cost; and the method is simple in technical principle and easy to operate, saves a large amount of manpower and material resources, greatly improves the efficiency of making the section boards, avoids errors caused by manual drawing of section data, and is worthy of popularization and application in a large amount of the river model tests in the future.

Description

Technical field [0001] The invention relates to a method for manufacturing a broken panel for river engineering model tests, and belongs to the technical field of river engineering model tests. Background technique [0002] The river engineering model test is to reduce the prototype river channel to a certain scale according to the similar laws of water flow and sediment movement, and reproduce the water flow and sediment movement in the laboratory to realize the simulation of the river channel. [0003] The river engineering model generally adopts the cross-section control method when making the river engineering model. First, determine the simulation range, that is, the model boundary, and then define the control section required to make the model in the river topographic map according to the trend of the river. The control section must be able to reflect the overall morphological changes of the river. The cross section of the river course is locally deformed, generally perpendic...
