Preparation method and test method of long-distance pressure water conveyance project overall model
The invention provides a preparation method of an integral model of a long-distance pressure water conveyance project, which comprises the following steps: determining a geometric scale of a pipeline model and an actual pipeline according to test conditions, determining basic parameters of the pipeline model according to a similarity rule and the geometric scale, calculating the total head loss according to the basic parameters of the pipeline model, and calculating the overall model of the long-distance pressure water conveyance project. A plurality of resistance rings are installed in the pipeline model to form a head loss replacement section used for replacing the total head loss of the pipeline model; the resistance rings are installed in the pipeline model to form the head loss replacement section for replacing the total head loss of the pipeline model, the overall length of the long-distance pressure water delivery engineering model is greatly shortened, the head loss of a long-distance water delivery pipeline can be simulated only by adopting the short head loss replacement section, and the construction efficiency is improved. And the site limitation for carrying out the model test is reduced, and the overall research and design optimization of similar projects are facilitated.
本发明提供了一种长距离有压输水工程整体模型的制备方法，包括：根据试验条件确定管道模型与实际管道的几何比尺，根据相似规律及几何比尺确定管道模型的基本参数，根据管道模型的基本参数计算总水头损失，在管道模型内部安装若干个阻力环构成水头损失替代段，用于替代管道模型的总水头损失；本发明通过在管道模型内部安装若干个阻力环构成水头损失替代段，用于替代管道模型的总水头损失，极大地缩短了长距离有压输水工程模型的整体长度，只需要采用较短的水头损失替代段即可模拟长距离输水管道的水头损失，减小了进行该模型试验的场地限制，便利了对类似工程的整体研究和设计优化。
