Closed lateral-symmetry horn mouth water inlet method for river model test

Abstract

The invention discloses a closed lateral-symmetry horn mouth water inlet method for a river model test. The method comprises the steps that firstly, a closed water inlet tank is manufactured; secondly, curing and pouring are carried out; thirdly, water storage is carried out; fourthly, water is fed to the water inlet tank; and fifthly, colliding energy dissipation is carried out, and water flow issimulated. According to the method, the water flow which is more stable and relatively free of acceleration can be simulated, and the test result is more accurate.

Description

technical field

[0001] The invention relates to a water inlet method of a closed lateral symmetrical bell mouth for a river engineering model test, and belongs to the technical field of river engineering model tests. Background technique

[0002] The water supply of the water tank is one of the key technologies of the river engineering model test. Any river engineering model test needs water supply to carry out relevant tests. Therefore, the water tank for the model test is directly related to whether the river engineering model simulation can be carried out normally.

[0003] During the river engineering model test, if the pipeline is directly connected to the model river bed, it will seriously interfere with the actual water level and flow velocity of the river and other hydrodynamic parameters, and it will also cause scour to the river, which will directly lead to the failure of the model test. In a normal model test, the upstream will maintain a slow overflow or a unifor...
