Embodiment Construction

[0019] The present invention takes the Qiantang River estuary model Gaza system as an example to illustrate specific implementation schemes.

[0020] Such as figure 2 As shown, the system consists of a sand mixing tank 1, a submersible mixer 2, a submersible sand delivery pump 3, a sand delivery pipeline inlet pipe 4, a sand delivery pipeline return pipe 5, a control gate valve 6, a model sand adding device 7, a pressure regulating device 8, Computer and its control software 9 and so on.

[0021] The mixing tank 1 is made of concrete, which is used to prepare and accommodate sandy and muddy water. The size of the capacity depends on the amount of sand added to the tidal estuary sediment model. In this embodiment, the mixing tank is 2 meters deep, 3 meters in diameter, and has a water capacity of about 14 cubic meters, the mixing tank is 1 meter above the ground, buried 1 meter in the ground, and the structure is reinforced concrete.

[0022] The submersible mixer 2 is insta...

Abstract

The invention relates to a sediment adding facility for sediment removal test by a tidal estuary sediment physical model and provides a system which can control sediment adding time and sediment adding quantity in time according to the range and variation process of a tide so as to meet the working requirement of the tidal estuary sediment physical model. In the technical scheme of the invention,the in-time sediment adding system for the tidal estuary sediment physical model is characterized by comprising a sediment stirring pond, a model sediment adding device and a sediment transmission pipeline, wherein the sediment stirring pond is provided with a submersible mixer and a submersible sediment pump, the model sediment adding device is arranged at an estuary model and controlled by a computer, the two ends of the sediment transmission pipeline are respectively communicated with the sediment stirring pond and the model sediment adding device, the sediment transmission pipeline is also provided with a control gate valve and a pressure regulator and consists of a water inlet pipe and a return water pipe, wherein the tail end of the water inlet pipe is divided into two branches, onebranch is communicated with the control gate valve through a flange and the other branch is communicated with the return water pipe.

Description

technical field [0001] The invention relates to a sand-gathering facility required for a tidal estuary physical model to carry out sediment erosion and deposition tests. Background technique [0002] The physical model test of estuaries is an important means of estuary management, port and navigation regulation, and wading engineering research. The topographical changes of estuaries and riverbeds caused by sediment erosion and deposition are the main research objects of dynamic bed model tests. In order to effectively reproduce the phenomenon of water and sediment movement in a tidal estuary, the physical model of the estuary should follow similar principles of geometry, dynamics and dynamics. When it comes to the simulation of sediment movement, in addition to the reasonable selection of model sand, it is also required to control the process and amount of sand added to the model. The traditional method generally adopts the circulation method, opening orifices of different ...
