Electro-osmosis-MICP combined foundation pit water stopping and reinforcing device and foundation pit water stopping method
The invention discloses an electroosmosis-MICP combined foundation pit water stop reinforcing device and a foundation pit water stop method, and relates to the field of foundation pit construction. The electroosmosis-MICP combined foundation pit water stopping and reinforcing device comprises a liquid storage tank, at least two water pumps and at least one probe rod. The probe rod comprises an inner cylinder, an outer cylinder arranged on the inner cylinder in a sleeving mode and at least two groups of electrodes, the groups of electrodes are arranged at intervals in the axial direction of the outer cylinder, a liquid injection hole is formed in the top of the inner cylinder, the outer cylinder is provided with a water pumping cavity and water outlet holes communicated with the water pumping cavity, the outer cylinder is provided with liquid outlet cavities corresponding to the groups of electrodes, and a plurality of liquid outlet holes communicated with the liquid outlet cavities are formed in the outer wall of the outer cylinder. The outer wall of the inner cylinder is provided with communicating ports communicated with the liquid outlet cavities, the liquid outlet cavities are internally provided with air bags which can be expanded and contracted to be cut off or communicated with the liquid outlet cavities, and the outer wall of the outer cylinder is provided with a plurality of water pumping holes communicated with the water pumping cavity; a water pump is respectively connected with the liquid injection hole and the liquid storage tank, and is connected with the water outlet hole. The electro-osmosis-MICP combined foundation pit water stopping and reinforcing device and the foundation pit water stopping method can stop water and reinforce a low-permeability soil foundation pit.
