Experimental investigation on prefabricated horizontal drain-based vacuum dewatering-solidification combined method for treatment of dredged slurry

open access: yesYantu gongcheng xuebao, 2023
The dredged slurry exhibits the characteristics of high water content, low permeability, high compressibility and low or negligible bearing capacity, and is difficult to be rapidly treated and disposed of. Aiming at this problem, a composite method, i.e.,

Experimental investigation of sludge dewatering for single- and double-drainage conditions with a vacuum negative pressure load at the bottom.

open access: yesPLoS ONE, 2021
The moisture content of municipal sludge is relatively high, which increases the cost of sludge transportation and treatment. To reduce the volume of the sludge, sludge dewatering is needed.

New Technique for Producing Vacuum Concrete [PDF]

open access: yesEngineering and Technology Journal, 2015
In this work a new technique is used to produce vacuum dewatered concrete. In this technique perforated PVC pipes encased in cotton cloth are used to dewater concrete from inside of concrete volume, rather than from the surface, as is the case in the ...

Study on Stability of Tunnel Surrounding Rock and Precipitation Disaster Mitigation in Flowing Sand Body

open access: yesGeofluids, 2021
Flowing sand is a special surrounding rock encountered by tunnel construction. Due to the looseness and low viscosity of the flowing sand, after excavation, the sand body is easy to flow along the open surface.
