Vacuum preloading combined with multiple-flocculant treatment

To address this issue, this paper proposes a method of multiple-flocculant treatment combined with vacuum preloading for improving dredged slurry. This is achieved by pre-treating the dredged slurry with lime and anionic polyacrylamide (APAM) prior to vacuum preloading. In this method, the additions of lime and APAM in a certain quantity allow

Ultrasoft Ground Treatment of Vacuum Preloading Combined with

Vacuum preloading is one of the popular methods improving the engineering properties of slurry ground with high water content. Commonly, the efficiency of vacuum preloading gradually decreased due to the clogging of prefabricated vertical drains (PVDs) and the low-vacuum transmission rate inside slurry. Thus, the calcium-based flocculants were used to accelerate the dewater capacity and

Analysis of the Effectiveness of the Step Vacuum Preloading

As a solution to avoid the blockage of the drainage pipe by traditional vacuum preloading, step vacuum preloading (SVP) has been progressively studied. However, the effectiveness of this technique has yet to be systematically analyzed. In this study, an indoor model test was conducted in which vacuum pressure was applied in five stages (10, 20, 40, 60, and 80 kPa) to dredger soil with high

sedimentation behavior of flocculant-treated soil slurr

Sedimentation behavior of flocculant-treated soil slurry. Slurry sedimentation tests on slurries with different flocculant contents and water contents were conducted. It is shown that, by adding flocculant into soil slurry, the rate of settlement under self-weight can be considerably increased in the tested range of water contents (100.7–879.5%).
