Description

technical field [0001] The invention relates to a soft ground reinforcement device and method thereof. Background technique [0002] Reuss first discovered electroosmosis in clay in 1809, and Casagrande first applied electroosmosis to civil engineering in 1939. After that, scholars from various countries have carried out some research work on the mechanism and application of electroosmosis. The electroosmosis method is to pass direct current on the electrode buried in the soil to form an electric field, and the water in the soil is discharged under the action of the electric field. The principle can be explained as follows: fine-grained soil is usually negatively charged, resulting in the presence of hydration cations balanced with it in the pore water. Under the action of the electric field, the hydration cations move to the negative electrode and drive the water molecules to move together to achieve drainage. The construction load of the electroosmosis method is small, a...
