Construction technology of vibrating and squeezing gravel piles
The construction principle of vibrating and squeezing gravel piles Vibrating and squeezing gravel piles is to squeeze soil to create holes through vibrating immersed tubes, fill pile materials in layers and vibrate The reinforcement mechanism of solid piles is to replace and seal the soil, promote drainage and consolidation, and thereby improve the bearing capacity of the composite foundation. Scope of application of secondary vibrating gravel piles: This method is often used to reinforce weak foundations, reinforce dam slopes, eliminate the liquefaction of liquefiable soil, eliminate the collapsibility of collapsible loess, and is suitable for sandy soils, silt soils, and sticky soils. Soil, silt soil, organic matter, loess, etc. The pile length can reach ~ meters and the pile diameter ~ meters, and it does not pollute the environment. Its main advantages are low cost and fast progress, good reinforcement effect, and wide application range. Therefore it is widely used.
