Cylindrical composite electrode and consolidating device for electrochemical consolidation of soft soil

Abstract

The invention discloses a cylindrical composite electrode and a consolidating device for electrochemical consolidation of soft soil, wherein the cylindrical composite electrode comprises metallic cylinders and metallic rods arranged at the circle centre of the metallic cylinders; the metallic cylinder is combined with the metallic rod to form a positive and negative electrode pair; the radius of the metallic cylinder is 100-200 mm, the wall thickness of the metallic cylinder is 3-5 mm, and the diameter of the metallic rod is 10-14 mm. the composite electrode disclosed by the invention is composed of the metallic cylinder and the single metallic rod; each electrode pair in a consolidating region is equally spaced; the electrodes of all the metallic cylinders are connected in series by a cable; the electrodes of the metallic rods are also connected in series by the cable; the pile-forming radius of an electrochemical cement pile is controlled and regulated through regulating the radius of the metallic cylinders. The method provided by the invention is simple with convenient operation and low cost, providing an effective way for effectively enlarging the pile-forming radius of the electrochemical cement pile of soft soil and increasing the overall bearing capacity of a foundation.

Description

technical field [0001] The invention belongs to the technical field of soft soil reinforcement, and more specifically relates to a cylindrical composite electrode and a reinforcement device for electrochemical reinforcement of soft soil. Background technique [0002] Our country has a vast territory, and the engineering geology is very complicated. Among them, the soft soil deposited in the coastal, river, river, and lake facies, as bad engineering geological bodies, is ubiquitous. With the rapid advancement of my country's infrastructure projects, a large number of railways, highways, airports and houses need to be built on soft soil foundations. However, due to the low bearing capacity and high compressibility of soft soil itself, it is easy to cause excessive foundation deformation. and building structural instability. Therefore, the soft soil foundation must be treated to ensure the safety and stability of the project construction. [0003] The soft soil electrochemical...
