Embodiment Construction
[0017] The present invention will be described in further detail below according to accompanying drawing:
[0018] according to figure 1 , figure 2 It can be seen that a triangular arrangement composite electrode for electrochemical reinforcement of soft soil includes electrode type and size, electrode combination and arrangement spacing, and is characterized in that: a single electrode type is a cylindrical metal rod 1, and each positive and negative The first stage is a composite electrode formed by combining a single electrode. The composite electrode is composed of three cylindrical metal rods 1 arranged in a triangle, and a certain distance is left between the metal rods 1; the three metal rods are inserted into the soft soil foundation 3 and passed through the cable. Lines 2 are connected in series to form composite electrodes; composite positive electrodes and composite negative electrodes in the reinforcement area of soft soil foundation 3 are grouped and arranged...

Abstract
The invention discloses a triangularly arranged compound electrode of soft soil electrochemistry solidification. The arrangement method thereof is as follows: arranging three column-shaped metal rods to form an isosceles triangle with certain interval between the metal rods, and connecting the metal rods in series via cable conductors to form a compound anode or a compound cathode; and controlling the radius of the compound pile of the electrochemistry cementing pile by adjusting the diameter and interval of the metal rods. The method is simple, is convenient to operate, has low expense, and provides an effective approach for enlarging radius of soft soil electrochemistry cementing pile, and improving overall carrying capacity of the groundwork.
Description
technical field [0001] The present invention relates to the technical field of soft soil reinforcement, and more specifically relates to a triangular arrangement composite electrode for electrochemical reinforcement of soft soil, which is suitable for pile reinforcement by electrochemical cementation of soft soil, and provides a method for increasing the pile diameter of artificial cemented piles in soft soil. an effective method. 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 aluminum roads, 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 De...
