Large diameter vibrating immersed tube rubble pileIs the use of high-power vibration hammer as the driving force, the steel feed pipe sunk into the design depth, and through the hopper, the bin will fill the gravel, and then vibration pull out the feed pipe, the final formation of deep and large diameter, composed of gravel compacted pile body. Compared with the traditional technology of gravel pile, Shanghai Qiangqiang has mature construction technology and experience, and has dozens of gravel pile construction equipment, which has been successfully used in many large-scale foundation treatment projects at home and abroad.
Gravel piles are made of crushed stone(The pebble)Composite foundation reinforcement pile made of main material. Gravel pile is a kind of granular pile, which can be divided into vibroflotation according to its pile making technology(wet)Gravel pile and [1] There are two kinds of dry gravel piles. The crushed stone pile made by vibration and water flushing is called vibroflotation crushed stone pile or wet crushed stone pile. Adopt all kinds of waterless flushing process(Such as dry vibration, vibration squeeze, hammer, etc)Made of gravel pile is collectively known as dry gravel pile. When gravel sand, coarse sand, sand, round gravel, breccia, pebbles, gravel and other filling materials made of pile called sand pile.
Gravel pile is suitable for compaction of loose sand, silt, plain fill and miscellaneous fill soil foundation. Among all kinds of piles in composite foundation, gravel pile and sand pile belong to granular material pile, and their reinforcement mechanism is similar. The mechanism is different with different soil quality: it has displacement and compaction effect on sand, silt and gravel; For clay soil and fill soil, displacement is the main effect, and it also has the effect of different degrees of compaction and promoting drainage consolidation. Gravel pile is mainly used in engineering to strengthen weak foundation, embankment slope, eliminate liquefaction of liquefaction sand, eliminate collapsibility of collapsible loess and so on.
