Embodiment 1
[0060] In a test site in Zhejiang, the soft soil foundation was reinforced with an area of 1,000 square meters and a treatment depth of 8 meters. See figure 2 , image 3 .
[0061] 1. Preparation work before composite electroosmosis and AC shock drainage:
[0062] a. Level the site, remove sharp objects, and carry out the construction lofting at the 8 position of the composite pipe according to the distribution of the mesh cap hole vacuum film 11 mesh on the flat surface, such as image 3 As shown, the mesh spacing is set to 1 meter.
[0063] b. Prepare mechanical equipment and materials: including mesh cap-eye vacuum membrane 11, vacuum pump 10, electric shock meter 6, composite pipe 8, horizontal drain pipe 9, water collection pipe 12, etc.
[0064] c. Laying composite pipes: such as figure 2 , image 3 . ① Use a water gun to form holes according to the mesh position of the membrane; ② Then sink a sand column bag with a certain length of sand into the hole; ③ Insert a composite ...

[0073] In a test site in Guangdong, the silt reclaimed soil was treated with a trough as a carrier. The trough was 12 meters long, 4 meters wide, and 2 meters high. See attached Figure 4 .
[0074] 1. Carry out preliminary preparations:
[0075] a. A set of composite pipes 8 are inserted in the tank, and electrode nets 18 and infiltration devices 14 are arranged on the walls of the tank body 15; then the sludge is put into the tank, and the mud surface is flush with the notch.
[0076] b. Lay the open-hole redundant film 17 on the mud surface. When laying the film, reserve a certain area of redundancy at the position of each composite pipe 8 so that this redundant area wraps the upper outer wall of the composite pipe 8 and is elastic The hoop seals the membrane 17 with the outer wall of the composite pipe 8, and then opens a hole at the position where the membrane is located on the composite pipe mouth, so that the composite pipe extends out, and then checks the lap joints, the ti...

[0085] In a test base in Guangdong, the sludge fertilizer was dewatered with a container 20 as a carrier. The container is a hollow cylinder with a radius of 2 meters and a height of 1.5 meters. See attached Figure 5 .
[0086] 1. Carry out preliminary preparations:
[0087] a. Set the electrode net 18 and the percolating device 14 on the inner surface and bottom of the container top cover, add the sludge into the container, cover the piston type top cover, and seal it so as not to leak. At the same time, apply a radius of 1.8 on the top cover Meters, 1 meter high, there is a hole in the center of the cement pier to statically load the silt.
[0088] b. Connect the horizontal drain pipe 9 to the container top cover joint 22 and the bottom joint 23, and the horizontal drain pipe 9 to the vacuum pump 10.
[0089] c. The electrode net joint 19 and the composite pipe 8 are connected to the electroosmosis meter 6 through the power line 7.
[0090] 2. Carry out 36 hours of vacuum pumping.
