Device and method for measuring hydrotechnics and river engineering model altitude

Abstract

An elevation device for measuring hydraulic and river engineering models by using a communicating pipe comprises an existing fixed datum elevation point (1) of a model, and an independent buried pipeline (2). One end of the buried pipeline is positioned in a model river channel; a water level station (3) is arranged at the other end of the buried pipeline (2); a matching needle water level gauge (4) is arranged on the water level station (3); a pipeline valve (6) is arranged between the buried pipeline (2) and the water level station (3); and a first communicating valve (7) and a second communicating valve (8) are arranged on a communicating pipe (5) which is positioned on the water level station (3). The elevation device overcomes the shortcomings of low measuring precision, high time and labor consumption etc. of the prior hydraulic and river engineering elevation control system. At the same time, the invention discloses a method for conducting height measurement for models by utilizing the measuring device.

Description

technical field [0001] The present invention relates to a high-precision measuring device for the elevation control system of hydraulic and river engineering models, more specifically, it is a device for measuring the elevation of hydraulic and river engineering models using connecting pipes, and the invention also relates to the use of this measurement The method by which the device takes model elevation measurements. Background technique [0002] The accuracy of the elevation control system of hydraulic and river engineering models directly affects the reliability of test results. Therefore, it is necessary to frequently measure and check the elevation control system of the model, which is a key basic work for hydraulic model tests. The commonly used method for measuring the model elevation system is: set multiple elevation base points within the model range, use the level instrument to measure the elevation of other base points one by one from the initial reference point,...
