Embodiment Construction

[0031] Referring to Fig. 1, the method for treating large-area soft ground layered and divided by electroosmotic dewatering combined with vacuum dewatering in the present invention, the specific process of the method is as follows:

[0032] 1. Layering

[0033] According to the construction area to be reinforced, 5000-10000m for each community 2 Divide and arrange deep electroosmotic well point tubes and shallow vacuum well point tubes

[0034] 1. Set up deep electroosmotic well point pipes (electroosmotic dewatering well pipes)

[0035] a) Set the cathode well point tube: set the length of the cathode well point tube and the range of the suction filter head according to the burial depth of the muddy soil. Generally, the cathode well point tube adopts Φ32mm, the tube length is 6.0m, and the filter head length is 1.5-2.0m.

[0036] b) Set the anode rod

[0037] After setting the specific data of the cathode well point tube, set the anode rod according to the data of the cath...

Abstract

The present invention relates to a stratified time-after-time electroosmotic precipitation combined vacuum precipitation method for treating large-area soft ground base. It is characterized by that on the large-area soft ground base a stratified time-after-time electroosmotic precipitation combined vacuum precipitation method is adopted, the described stratified precipitation is characterized by that in the deep layer an electroosmotic well-point pipe electroosmotic precipitation is adopted, and in the shallow layer a vacuum well-point pipe evacuation precipitation is adopted; the described time-after-time precipitation is characterized by that in the area where the deep-layer electroosmotic well-point pipe precipitation is adopted in last-time precipitation construction the above-mentioned shallow-layer vacuum well-point pipe precipitation is adopted in the next-time precipitation construction; and in the area where the shallow-layer vacuum well-point pipe precipitation is adopted in last-time precipitation construction the above-mentioned deep-layer electroosmotic well-point pipe precipitation is adopted in the next-time precipitation construction.

Description

Technical field: [0001] The invention relates to a method for treating soft ground, in particular to a method for treating large-area soft ground in layers, dividedly, and combined with electroosmotic dewatering and vacuum dewatering. Suitable for weak ground treatment. It belongs to the technical field of foundation treatment. Background technique: [0002] At present, in the construction of large-area soft ground dewatering, a single method of vacuum dewatering, light well point dewatering and electroosmotic dewatering is often used. In construction, the single precipitation construction method has the following defects: [0003] 1. Vacuum well point precipitation [0004] This method is only applicable to the permeability coefficient K≥1×10 -4 For large-area precipitation construction with soil quality above cm / s, because the precipitation curve is relatively flat, when the soil permeability coefficient K≥1×10 -4 The precipitation effect at cm / s is unmatched by light...
