Device and method for treating dredger fill by combining supercharged vacuum preloading with solar intermittent electroosmosis

Abstract

The invention relates to a device and method for treating dredger fill by combining supercharged vacuum preloading with solar intermittent electroosmosis. The device and method are used for reinforcing the dredger fill; a composite electric supercharged drainage plate is formed by superposing a front layer, a middle layer and a rear layer of a base board; a layer of conductive geotextile filter membrane is arranged on the surface of the base board; the front layer of base board and the rear layer of base board are vacuum drainage plates; the middle layer is a pressurizing plate; the vacuum drainage plates are provided with longitudinal ties; drainage grooves are formed between the longitudinal ties; holes are formed in the longitudinal ties and communicate with pressurizing guide grooves in the pressurizing plates; a metal copper fiber mesh is arranged in the middle of the pressurizing plate; a composite hand-shaped connector is inserted into the top of the composite electric pressurization drainage plate;, an inner ring partition plate is arranged in the composite hand-shaped connector in a protruding mode and inserted into a square insertion groove; and a vacuum interface, a pressurization interface and a wire interface are formed in the top of the composite hand-shaped connector. Intermittent electrification is achieved, environmental protection and energy saving are achieved, the problem of serious electrode corrosion is solved, the solidification period of a dredger fill foundation subjected to vacuum preloading is shortened, the leakproofness is better, and the drainage efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of dredging and filling soil reinforcement treatment, in particular to a composite electric pressurized drainage board device and a method for boosting vacuum preloading combined with solar intermittent power supply and electroosmotic reinforcement of dredging and filling soil. It is mainly applicable to the field of land reclamation engineering technology such as coastal flats and depressions. Background technique [0002] With the rapid development of economic construction in coastal cities in our country, land resources are becoming increasingly scarce. In recent decades, China's coastal cities have carried out land reclamation successively to alleviate this situation. The land reclamation method is a good method for channel dredging and land formation, and it is also the main method for land reclamation in my country at present. However, since dredger fill usually has the characteristics of "three high...
