Embodiment Construction

[0020] The present invention will be described in further detail below according to accompanying drawing:

[0021] According to Fig. 1, it can be seen that the model test device for strengthening soft soil by electrochemical pile forming method consists of a metal electrode 1, a high-power regulated voltage and current DC power supply 2, an ammeter 3, a cable 4, a soil sample box 5, a porous permeable plate 6, water A valve 7, an exhaust valve 8, a water pipe 9, a Martens jar 10, a soil sample 11, and pure water 12 constitute.

[0022] It is characterized in that: the soil sample box 5 is made of plexiglass or engineering plastics, and is roughly a square box of 600mm x 600mm x 600mm. A porous permeable plate 6 is horizontally arranged at a distance of about 100mm from the bottom of the soil sample box 5. The porous permeable plate 6 and the The four walls of the soil sample box 5 are firmly cemented with structural adhesives; under the porous water-permeable plate 6, the two ...

Abstract

The present invention discloses a test device used for reinforcing a soft soil model with an electrochemical pile-making method. The present invention comprises a metal electrode, a soil sample box, a porous permeable panel and a Markov bottle, wherein, the porous permeable panel is arranged at the bottom part of the soil sample box, and the porous permeable panel and the four walls of the soil sample box are firmly cemented by adopting structural adhesive; the metal electrode is vertically inserted in the soil sample inside the soil sample box, and is connected with a high-power steady voltage and steady flow direct current power supply through a cable, an ammeter is connected in series with the high-power steady voltage and steady flow direct current power supply, a water valve and an exhaust valve are arranged at the lower part of the side wall of the soil sample box, and the water valve is connected with the Markov bottle through a water pipe. The present invention has rational and simple structure and convenient operation, and the conditions of the soft soil foundation at the scene can be simulated to control the underground water level, and the present invention can be used for the test reinforcing the soft soil model with the electrochemical pile-making method.

Description

technical field [0001] The invention relates to the field of soft soil foundation reinforcement, and more particularly relates to a model test device for strengthening soft soil by an electrochemical pile forming method, which is suitable for a model test of soft soil reinforced by an electrochemical pile forming method. Background technique [0002] my country has a long coastline, and there are rich marine sedimentary soft soils along the coast; there are also many rivers, rivers, and lake sedimentary soft soils in China. With the development of the national economy, it is inevitable to build certain geotechnical engineering on these soft soils. However, these soft soils have low strength and high compressibility, far from meeting the needs of the project, and must be properly reinforced before they can be used. [0003] There are many methods of soft soil reinforcement, but different reinforcement methods have their own characteristics and scope of application. Common t...
