Model considering estuary spur dike construction process and test method thereof

Abstract

The invention belongs to the technical field of estuary engineering, and particularly discloses a model considering the estuary spur dike construction process and a test method thereof.The model comprises a water tank and a water flow adjusting control end; gates are arranged at the front end and the rear end of the water tank, and a bottom slope is arranged at the bottom end of the water tank; a lower groove is formed in the middle of the water tank, a plurality of cylindrical supporting frames are pre-buried in the lower groove, and spur dike models are arranged at the tops of the cylindrical supporting frames; a topographic instrument is arranged at the top of the lower groove; a propeller flow velocity meter and a water level sensor are arranged on the front side of the lower groove in the water tank; the propeller flow velocity meter, the water level sensor, the gate and the bottom slope are electrically connected with the water flow adjusting control end. According to the model considering the estuary spur dike construction process and the test method of the model, dynamic changes in the construction process can be fully considered, the scouring and silting conditions of a riverbed in the spur dike construction process are evaluated under the complex hydrodynamic force condition of estuary reciprocating flow, and the construction efficiency of the spur dike is improved. And a certain technical support is provided for design and construction of a temporary spur dike project.
