Problems solved by technology

However, the existing electroosmosis method for soil slope (subgrade) reinforcement is not perfect, and the process is to consider inserting electrodes vertically downward from the road surface for reinforcement treatment, which will inevitably affect the use of the road, and the cost is high and easy destroy the surrounding environment

Embodiment

[0033] The electroosmosis method used for soil slope (subgrade) reinforcement in this embodiment is realized through the following steps:

[0034] 1) According to the soil conditions of the site, determine the size of the cathode and anode, including length, inner diameter, outer diameter, layout distance and form of the cathode and anode, and the power supply method.

[0035] 2) Customize the cathode and anode according to the established indicators. The cathode uses a conductive plastic tube, which is perforated and wrapped with geotextiles. The anode can be made of a metal rod or a conductive plastic tube, which does not need to be punched or wrapped.

[0036] 3) Arrange points in the site according to the determined layout spacing and form.

[0037] 4) if figure 1 As shown, the cathode 1 and the anode 2 are inserted into the soil mass of the soil slope 3 manually or mechanically through holes according to the soil quality. Cathode 1 is inserted into the soil horizontall...

Abstract

The invention discloses an electro-osmosis method for reinforcing a soil side slope. The electro-osmosis method for reinforcing the soil side slope comprises the following steps of horizontally inserting downwards anodes at a certain small angle and horizontally inserting upwards cathodes at a certain small angle into a soil body, and then connecting the anodes with the cathodes to form an electro-osmosis system. After electro-osmosis treatment, the soil body is decreased in water content and improved in shear strength, and the purposes of reinforcing a road bed, preventing a side slope from sliding or protecting a foundation ditch are realized. According to the electro-osmosis method for reinforcing the soil side slope, the electro-osmosis reinforcement is carried out on the side slope by utilizing reasonable construction angles, and not only can an existing road bed be reinforced and can electrodes be directly driven into the side slope to treat the side slope, but also the method does not need large scale equipment and is convenient in construction.

Description

technical field [0001] The invention relates to an electroosmotic reinforcement soil technology, which is used in the field of soil reinforcement such as electroosmotic reinforcement of soil slopes for anti-skid, roadbed reinforcement without damaging existing road surfaces, reinforcement and protection of excavation of foundation pits, etc., specifically relates to a Electroosmotic method for soil slope stabilization. Background technique [0002] There are muddy soft clay layers widely distributed in the coastal areas of our country. When building roads in these areas, limited by the construction period and site conditions, sometimes we have to use over-wet soil to fill the roadbed. These soft clays have high water content, poor permeability and low strength. , showing strong under-consolidation, based on the fact that most of the first-class highway projects are high-fill embankments, which will directly affect the settlement of the subgrade and the stability of the high-...
