The invention discloses a test method for accelerating the erosion of grouted stone bodies by using a device for simulating seawater pressure and flow, wherein the device includes: an air compressor, the air outlet of the air compressor is respectively connected with two pressure supply ports through a first pipeline The air inlet of the water tank is connected. The first pipeline is equipped with a pressure gauge and an electronically controlled air valve. The water outlets of the two pressurized water tanks are connected with the water inlet of the erosion test tank through the second pipeline. The first electric control water valve and the first flow control water valve, the water outlet of the erosion test pool is connected with the water inlet of the water storage tank through the third pipeline, the second flow control water valve is arranged on the third pipeline, and the water pump is installed in the water storage tank , the water pump communicates with the water inlets of the two pressurized water tanks through the fourth pipeline, and the second electric control water valve is installed on the fourth pipeline; the pressure gauge, electric control air valve, electric control water valve, flow control water valve and water pump are Connect with the controller. The test environment of the invention is more real, has high efficiency, can be recycled, and reduces the cost.
Description
technical field [0001] The present invention relates to a marine test device and method, in particular to a test device and method for simulating seawater pressure and flow characteristics of the erosion law of grouted stones, which can simulate the seawater pressure and flow characteristics of grouted stones in actual engineering, The grouting reinforcement ring used to simulate subsea tunnels and other subsea geotechnical engineering is subjected to erosion tests under seawater pressure and continuous flow conditions. Background technique [0002] With the proposal of the 21st Century Maritime Silk Road and the country's policy of developing the ocean, the demand for transportation links between the long coastline in my country's coastal areas and the dotted islands has become the biggest driving force for the construction of subsea tunnels and other subsea underground projects. However, engineering disasters such as mud inrush and water inrush faced by subsea tunnels when...
