BVEM company profile (Beijing vibroflotation engineer machinery
co.,ltd)
Company is establish in 2007, the company comes from the equipment
department of Power china vibroflotation company.
Company vision : Outperform to Serve Vibroflotation.
1. Papers were published in Chinese Joumal of ground improvement
<bottom feed vibraflotation application in soil improvement
engineering>
<Application of real time process data in whole process quality
control of vibro replacement stone column>
2. The first complete set of bottom feed vibroflot R&D and
supplier
3. The first manufacturer of hydraulic vibroflot in China
4. The first enterprise, who built and promote the vibroflotation
whole process quality control and mangement in China
The bottom feed vibroflot method is an extension of the traditional
top feed vibroflot method, which further expands the application
scope of vibroflotation method in all kinds of projects, it has
special advantages in the application of the following projects :
1. Silty or silty soil with too low strength
2. Underwater or offshore stone column construction
3. Dry method
Beside vibroflot system,bottom feed also equiped the materails
feeding system with Double lock pressure containes
Lifting equipment: can provide open interfaces for crane, pile
frame, and rotary drilling rigs
Ground Improvement by Deep Vibratory Methods
Effection:
1. Pre-settlement, complete the majority of the settlement before
the foundation bears the load of the structure
2. Increase the relative density of soil, reduce the uneven
settlement of foundation
3. Stone column can improve the drainage performance of soil,
accelerate the consolidation of soil, reduce settlement, improve
the bearing capacity and improve the anti-liquefaction performance
of soil, improve the seismic grade
Characteristic:
1. The equipment and material are simple, convenient and
economical.
2. It is especially suitable for the foundation treatment projects
of hydropower stations, petrochemical plants, port terminals, dams
and airport runways (to improve some bearing capacity, prevent the
uneven settlement of soil or to treat the anti-liquefaction ability
of the interlayer in some section of the foundation)
