Problems solved by technology

[0004] The traditional electrode material is a metal electrode. During the electroosmosis process, the metal ions electrolyzed near the anode will form a cement with the soil, which further improves the strength of the soil around the anode. However, the metal electrode is easy to corrode and cannot meet the long-term electroosmosis requirements. deal with

Embodiment

[0036] The tubular EKG electrodes used in this embodiment are as follows: figure 1 As shown, it is a conductive plastic tube made of graphite, polyethylene and other materials. The electrode tube wall is evenly distributed with grooves 16 along the axial direction, and drainage holes 15 are distributed between the grooves 16, and two holes are symmetrically penetrated in the tube wall. The metal wire 11 is used to connect the DC power supply 7 .

[0037] The specific structural layout of using electroosmotic soil piles to treat soft foundations is as follows figure 2 and image 3 As shown, it is specifically realized through the following steps during the construction process:

[0038] 1. A tubular EKG electrode is drilled in the soft soil foundation as the central electrode 1. The penetration depth of the tubular EKG electrode is determined according to the depth of the foundation to be treated. Taking the central line of the central electrode 1 as the axis, the secondary...

Abstract

The invention discloses a method for treating a soft foundation with an electroosmosis soil pile based on a tubular EKG electrode. The method comprises the steps of electrode arrangement, pipeline arrangement, electrode electrification, drainage and the like; the tubular EKG electrode is arranged in the soft soil foundation; sub-outer ring electrodes and outer ring electrodes are formed by taking the electrode as a center; and the electroosmosis drainage is performed for twice in sequence from the inside out. After electroosmosis completion, the soil strength in a sub-outer ring is improved to form an electroosmosis soil pile. The method is simple in construction technology and obvious in economic benefit, the electroosmosis soil pile formed after the electroosmosis can exert an effect of a pile foundation, and the method is suitable for reinforcement of the soft soil foundation.

Description

technical field [0001] The invention relates to the field of soft soil foundation reinforcement, in particular to a method for treating soft foundations with electroosmotic soil piles based on tubular EKG electrodes, and belongs to the field of geotechnical engineering. Background technique [0002] Silt soft clay layers are widely distributed in the coastal areas of my country. The particles of these cohesive soils are mainly clay and fine particles. The main characteristics are: high water content, poor permeability, low strength, and high compressibility. When building engineering buildings in these areas, the foundation must be reinforced to meet the engineering requirements. [0003] Commonly used soft clay foundation reinforcement methods include vacuum preloading method, pile foundation and so on. For cohesive soil with a small permeability coefficient, the vacuum preloading method has a long construction period, and it is difficult to achieve the expected reinforcem...
