Embodiment 1
[0040] Embodiment 1: Referring to Fig. 1, a composite vacuum preloading soft soil foundation reinforcement method, the method includes vacuum preloading dewatering and electroosmotic dewatering two parts, the construction steps are as follows:
[0041] a) Leveling the site and setting up a site drainage system; including a horizontal drainage system and a vertical drainage system, the horizontal drainage system is made up of drainage blind ditches, horizontal vacuum pipes 4 and sump wells, and the vertical drainage system is composed of plastic drainage boards and positive Negative electrode 2 composition.
[0042] Insert plastic drainage boards 1 on the site to be treated. The minimum distance between the plastic drainage boards is 1m×1m, and they are arranged in a plum blossom shape. High geotextiles ensure the smooth drainage of the vacuum system; insert positive and negative electrodes, which require good electrical conductivity, such as steel bars or aluminum rods or copp...
Embodiment 2
[0050] Embodiment 2: A kind of composite vacuum preloading soft ground reinforcement method, this method comprises vacuum preloading dewatering and electroosmotic dewatering two parts, and its construction steps are as follows:
[0051] a) Leveling the site and establishing a site drainage system; including a horizontal drainage system and a vertical drainage system. electrode composition.
[0052] Insert plastic drainage boards on the treated site, the minimum spacing of plastic drainage boards is 1m×1m, and they are arranged in a plum blossom shape. Plastic drainage boards must use high-performance plastic drainage boards to ensure the mechanical strength required for smooth vacuum. The filter membrane adopts high tensile strength. Geotextiles to ensure the smooth drainage of the vacuum system; insert positive and negative electrodes, which require good electrical conductivity, such as aluminum rods or copper rods, etc., and the depth and spacing are the same as plastic drai...
