The movie shows the micro-balance to ground resistance

میکرو بالانس

میکرو بالانس تکنولوژی انفجار استفاده شده است که در زمان ساخت جاده ها، مجموعه های صنعتی، بنادر، فرودگاه ها، موج شکن، سدها حفظ و ساختمان های دیگر. این کار باعث می شود  بهبود حجم زیادی از خاک ضعیف در یک زمان کوتاه و همچنین تضمین دریافت قدرت اولیه در مقدار پارامترهای است.

میکرو بالانس تکنولوژی انفجار بکاربردن انرژی حاصل از انفجاری کوچک  که باعث می گردد جابچای سطح روی و زیر زمینی  زمین می گردد.


MICROBLASTING

Micro blasting technology is used when constructing roads, industrial objects, ports, airports

breakwaters, retention dams and other buildings. It enables improvement of large volumes of weak soil in a short time as well as guarantees receiving first rate strength parameters

Micro blasting technology employs the energy of small explosive charges placed on surface, laid Underground or just above the bottom of the water body


Loose non-cohesive soil improvement (DDC – Deep Dynamic Compaction)

Microblasting causes saturated subsoil compaction. Thanks to excessive pressure in the soil pores previous structure of non-cohesive soil is destroyed and after a momentary liquefaction the particles settle in a denser configuration while water filters up to the surface. Repeating of blastings in series supports these processes. Microblasting may be successfully

applied underwater as well as on land


Saturated organic soil improvement (DDR – Deep Dynamic Replacement)

Microblasting technology enables significant acceleration of the consolidation process through formation of sand columns which act as drain channel and – at the same time – strengthen the subsoil. Explosive charges are installed in boreholes and detonated in a couple of specially designed sequence series

Additional layer of non-cohesive material, e.g. sand is temporarily liquefied into caverns (cavity formed as a result of the explosion) creating sand columns of big diameter (up to 2 meters


Safety

The microblasting technology is not hazardous to human life or health as well as neighbouring buildings

provided the soil improvement procedure is properly planned, carefully designed and neatly performed by qualified and experienced contractors and the right distance from the explosion site is kept (30-50) meters


Advantages

Efficiency

improvement of up to 10 000 000 m3 of subsoil per month

reduction of soil settlement in terms of live load to a level which is significantly lower than

specified by both Polish and foreign constructing standards

the depth of ground to be improved is theoretically unlimited

Effectivness

attaining high values of improved subsoil’s strength parameters

continuous quality monitoring of subsoil’s improvement

Rate of performance

much faster consolidation of subsoil in comparison to other soil improvement technologies

Economical aspect

low cost of performance in comparison to other soil improvement methods
