Triangularly arranged compound electrode of soft soil electrochemistry solidification

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 invention relates to the technical field of soft soil reinforcement, and more specifically to a triangular arrangement composite electrode for soft soil electrochemical reinforcement, which is suitable for electrochemical cementation of soft soil into pile reinforcement, and provides a way to improve the pile diameter of soft soil artificial cemented piles. An effective method. Background technique [0002] my country has a vast territory and complex engineering geology. Among them, soft soils deposited in coastal, river, river, and lake facies are ubiquitous as bad engineering geological bodies. With the rapid advancement of infrastructure projects in my country, 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, it is easy to cause excessive foundations. Deformation and instability and destruction of building structur...

Problems solved by technology

In the actual project of soft soil foundation reinforcement, although the diameter of the cemented pile can be enlarged by using the electrode with a larger diameter, due to the influence of the passivation of the metal electrode, the actual electrolytic thickness of the electrode is very limited. The main body of the pile is not electrolyzed, so that the contribution of the electrochemical cemented pile to the bearing capacity of the foundation is not as good as that of the metal electrode that has not been electrolyzed, which not only causes a waste of building materials, but also makes the electrochemical reinforcement of soft soil lose its original significance

However, if the electrode with a smaller diameter is used, the radius of the cemented pile is limited, and it is difficult for the pile-soil composite foundation to meet the design bearing capacity requirements after reinforcement

After searching the Chinese patent (patent application number: 200710052637.5, invention patent name: electrochemical pile method strengthening soft soil model test device) discloses a kind of electrochemical pile method strengthening soft soil model test device, Chinese patent (patent application number: 200810048489, Invention Patent Name: Electrochemical Strengthening Method for Soft Rock) discloses an electrochemical strengthening method for soft rock. These two patents both use a single iron rod as an electrode, and both have the problem of small cemented pile diameters
