Key technical points
1. Developed water vapor separation vacuum preloading device
The device consists of a power unit, a water gas separator unit, and a pipeline connection part within the area. The device separates the water and gas mixture extracted from the site through the device's water and gas separator. After the separated water reaches a certain water level, the automatic water level controller in the device automatically starts the built-in pumping pump of the water and gas separator to extract the water from the tank. The water and gas separator is connected to the variable frequency vacuum pump group in the power device, The variable frequency vacuum pump group can be adjusted through the variable frequency control system of the device to perform vacuum pumping operations. The frequency conversion vacuum preloading device for water and gas separation not only meets the construction process requirements, but also saves 30% of electricity compared to traditional vacuum preloading jet pumps.
2. Shorten the construction period
Greatly improve work efficiency, reduce energy waste, ensure project quality, effectively improve the efficiency of soft foundation treatment, and shorten the construction period by more than 30% compared to traditional vacuum preloading method.
3. Simple equipment wiring, safer electricity usage
A soft foundation treatment zone only needs to lay one cable and install an electric control box, avoiding the complex layout of cable lines for traditional vacuum preloading on-site equipment and the high risk factor of on-site electricity consumption, making electricity usage safer
4. More convenient for construction control and management
The auxiliary vacuum pump is used as the backup vacuum pump, and an automatic control system is fully adopted during the constant load preloading process, making construction more controllable and management more accurate.
5. Improve the key processes in the vacuum preloading construction process
The newly developed water vapor separation vacuum preloading device has a large controllable area, solving the problems of a large number of jet pumps in traditional construction processes and a large investment of equipment maintenance personnel.
6. Better construction quality
The vacuum negative pressure under the membrane can reach negative 85Kpa to negative 90Kpa, and the vacuum negative pressure and water vapor transmission effect are better. In terms of settlement rate, water content, bearing capacity, etc. of soft foundation treatment, it is significantly better than traditional vacuum preloading methods, effectively preventing water vapor mixture from damaging the vacuum negative pressure chamber's true space environment.
7. Improve the treatment effect of muddy soft foundation
The improved vacuum preloading construction process adopts a water vapor separation vacuum preloading device, which reduces the number of membrane trenches on the construction site by 30% compared to traditional construction techniques, improves the overall effect of soft foundation treatment engineering, and reduces the replacement amount of membrane trenches in the later stage, improves work efficiency, and reduces construction costs.
