Problems solved by technology

[0004] However, in the existing drainage process, multiple sets of metal electrodes are set up and electroosmosis is performed at the same time. After the water migrates from the anode to the cathode, the water content of the soil near the anode decreases, which increases the resistance and increases the energy consumption of drainage.
The method currently used is to reverse the electrodes at the same time, the original anode is transformed into a cathode, and the original cathode is transformed into an anode. method, which increases the energy consumption of soil reinforcement by electroosmosis, and reduces the efficiency of foundation treatment

Embodiment 1

[0044] Embodiment 1: A kind of ground treatment method of gradual electrification, such as figure 1 As shown, the direction of the arrow indicates the direction of progressive energization, including the following steps: preparation work, arrangement of conductive plastic drainage board, arrangement of drainage pipe 5, and progressive energization and electroosmotic treatment.

[0045] Preparatory work: Lay the cushion layer 2 on the surface of the soft soil foundation 1 that needs to be reinforced, divide the soft soil foundation 1 that needs to be reinforced into multiple construction areas, and construct on multiple construction areas at the same time to improve work efficiency. One end of the construction area is set as the starting working point, and the other end is set as the ending working point; the cushion layer 2 is a sand cushion layer, and the setting method in each construction area is the same.

Embodiment 2

[0053] Embodiment 2: a kind of ground treatment method of progressive electrification, such as image 3 As shown, the direction of the arrow indicates the direction of progressive energization. The difference from Embodiment 1 is that three adjacent conductive drains are set as a working unit. The first conductive drain part 3, the second conductive drain part 4, and the third conductive drain part are set as the first working unit 6; the second conductive drain part 4, the third conductive drain part, and the fourth conductive drain part are set as the second working unit Unit 7; ...; the 98th conductive drainage unit, the 99th conductive drainage unit, and the 100th conductive drainage unit are set as the 98th working unit.

[0054] Such as Figure 4 As shown, the direction of the arrow indicates the direction of progressive energization. During the energization process, firstly energize the first working unit 6, connect the first conductive drainage part 3 to the positive ...

Embodiment 3

[0055] Embodiment 3: a kind of ground treatment method of progressive electrification, such as Figure 5 As shown, the direction of the arrow indicates the direction of progressive energization. The difference from Embodiment 1 is that there is one starting working point and two ending working points. The starting working point is located in the middle of the construction area, and the ending working point is located in The two ends of the construction area are progressively energized from the middle of the construction area to the two ends of the construction area.

Abstract

The invention discloses a progressive electrifying foundation treatment method. The progressive electrifying foundation treatment method comprises the following steps of preparation work, arrangementof an electroconductive plastic drainage plate, arrangement of a drainage pipe, and progressive electrifying electroosmosis treatment. With the adoption of multiple working units, the multiple workingunits are subjected to progressive electrifying, so that progressive migration of moisture in a soil body is achieved, the energy consumption is reduced advantageously, and the foundation treatment cost is reduced advantageously.

Description

technical field [0001] The present invention relates to the technical field of ground treatment, more specifically, it relates to a progressive electrification ground treatment method. Background technique [0002] Soft soil, silt, sludge, tailings and other fine-grained media with high water content and low hydraulic permeability are very difficult to drain and consolidate. The traditional drainage consolidation methods are vacuum preloading and surcharge preloading. However, for fine-grained media with high water content and low hydraulic permeability, the traditional methods are slow, limited in depth, and insufficient in improving the bearing capacity. [0003] For soft soil foundations composed of such media, electroosmosis is a very potential method. It has been more than 200 years since electroosmosis was first discovered. The specific method is to insert a metal electrode in the soil and pass a direct current. Due to the action of the direct current electric field, ...
