Example Embodiment
[0035] Such as figure 1 , 2 As shown in and 3, a vacuum-electro-osmosis-heaping joint reinforcement system for soft foundations is composed of a retractable drainage electrode (2), a conductive circuit (11), a DC power supply (8), a horizontal drainage pipeline (10) and Vacuum pump (7) and other components.
[0036] A method of vacuum-electroosmosis-heap-loading joint reinforcement of soft foundation can be realized by the following technical steps:
[0037] (1) Arrange the site and lay a 30cm-50cm thick sand cushion (9).
[0038] (2) If the foundation is sandwiched with sand, a sealing wall (15) should be installed to prevent air leakage. Use a mixing pile machine to drive mud mixing piles, and the double rows of mixing piles overlap to form a clay sealing wall (15). The diameter of a single pile is 60cm-70cm, and the overlap is 10cm-15cm. The length of the pile must exceed the depth of the underground sand layer by more than 1m.
[0039] (3) Make drainage electrode (2), such as i...
