Embodiment

[0028] The annular electroosmotic single well drainage structure adopted in the embodiment of the present invention on the soft clay foundation is as follows: figure 1 and figure 2 As shown, there is a soft clay foundation 1 with a vertical single well 2 in the center, and a submersible pump 3 is placed at the bottom of the vertical single well 2, and the submersible pump 3 is connected with the outlet pipe 13 extending out of the well. The electroosmotic electrodes 4 are vertically driven into the clay foundation 1, and are distributed in a circular array with the center line of the single well 2 as the axis. All the electrodes 4 are connected by wires, and each circle of electrodes 4 is connected to each other independently by the same wire. A group of them forms the first conducting wire 5 , the second conducting wire 6 , the third conducting wire 7 , the secondary inner conducting wire 8 and the innermost conducting wire 9 arranged from outside to inside. Firstly, the fi...

Abstract

The invention discloses a treatment method for soft clay foundations of annular electroosmosis single well drainage. The method comprises the steps of excavating a single well, driving electrodes, conducting electroosmosis, conducting drainage and the like, wherein electrode annular arrays are driven into the soft clay foundations for multiple circles and distributed in the shape of a plum blossom; each circle of the electrodes is connected separately through a wire, the outermost circle of the wire is connected with a positive pole of a direct-current power supply, and a circle, next to the outermost circle, of the wire is connected with the negative pole of the direct-current power supply; circular electroosmotic flow from outside to inside is formed in clay through turning on the direct-current power supply, so that each two adjacent circles of electrodes are electrified from outside to inside in sequence; electroosmosis steps above are repeated till the water in the soft clay in the treatment scope is drained into the single well, and the water in the single well is drained into the earth surface. According to the treatment method for soft clay foundations of annular electroosmosis single well drainage, the operation is simple, and drainage reinforcement of the soft clay foundations is applicable.

Description

technical field [0001] The invention relates to a drainage reinforcement method for soft clay foundations, in particular to a method for treating soft clay foundations with annular electroosmotic single well drainage, and belongs to the field of geotechnical engineering. Background technique [0002] In my country's southeast coast and some inland areas, soft clay foundations are widely distributed. Soft clay is characterized by high moisture content, high compressibility, low strength, and poor water permeability. High compressibility leads to considerable settlement and settlement difference of the foundation, low permeability makes the settlement last for a long time, which may affect the normal use of the building, and low strength makes the bearing capacity and stability of the foundation unable to meet engineering requirements. [0003] Drainage consolidation methods such as vacuum preloading and surcharge preloading are commonly used to treat soft clay foundations. Va...
