Bamboo stakes and piles of Melaleuca :
 
Bamboo stakes and piles the solution Melaleuca traditional technology to handle background for light duty work on soft ground . Cajeput and bamboo pile length from 3 - 6 meters close to the ground with reinforced landing ink increases the load capacity and reduced settlement .
 
 
In my experience, often 25 bamboo or mangrove poles are closed for 1m2 . However should estimate bearing capacity and settlement of piles pile of bamboo or mangrove by methods routinely calculated . The use of mangrove poles in ground conditions and unreasonable load requires anti- subsidence small pile section .
 
Lime soil pile and soil cement
 
Equipment and technology used to Swedish soil and cement manufacturing and limestone soil . The findings in laboratory and field application shows :
 
 
 
- Lime soil piles and cement soil drainage role and reinforced base. This is the appropriate technology solutions to deep soft soil reinforcement.
 
- Indicators of intensity, deformation depends on the duration, type of substrate, organic content, particle size and concentration of cement and lime used.
 
- The use of cheaper cement in Vietnam conditions compared with lime. The percentage used is 8-12% and the percentage of cement is 12-15% dry weight of soil.
 
- Equipment capable Sweden soil cement pile construction.
 
- You can use regular devices have tried to check the quality stakes.
 
- Pile soil cement is used to reinforce the roadbed, house, industrial, background pier ...

Cement sand pile
 
Sand piles construction equipment could be used for construction of cement sand pile, steel pipe is closed and the ground vibration and weak occupied land. Sand and cement are mixed to flow into the casing.
 
 
Cement sand is compacted by the casing and vibration .
 
Rock piles and piles of compacted sand
 
To reduce subsidence and increased intensity soft soil , sand piles or pile has been compacted and rocky dung.Cat be compacted by vibratory system and can use technology in tube dress . Change the buried foundation depth to address subsidence and load capacity of the platform ; With increasing burial depth will increase the value foundation bearing capacity of the ground and reduces the stress caused subsidence to nail should reduce subsidence of the foundation .
 
 
Also increasing depth of the nail , the nail can put down the ground floor below the tighter , more stable . But rising buried deep foundation must weigh between two economic factors and technical . Change the size and shape of the nail will work to change the direct pressure exerted on the ground , and thus also improve the load conditions as well as conditions of the ground deformation . When increasing the area of foundation usually reduces the pressure exerted on the ground and reduce the subsidence of buildings . However compressible soil subsidence increases with depth , the measures are not entirely consistent .
 
 
Change the type of nails and hardness of nails to match the geotechnical conditions : You can substitute single nail by nail ice , ice interference nail , nails or nail box friends ; cored tape case which has large deformation should add strength to the foundation ; The hardness of the nail , nail larger ice deformation and the settlement will little baby . May use measures to increase nail thickness , increased load-bearing vertical reinforced , increasing structural rigidity above , arrange the ribs strengthen the foundations of a large size .
