Shanghai Strong foundation can be used to construct large diameter gravel pile, with mature construction technology and experience, and dozens of gravel pile construction equipment, which has been successfully used in many large-scale foundation treatment projects at home and abroad.

Large-diameter vibrating immersed tube crushed stone pile is a deep and large-diameter dense pile body composed of crushed stone formed by sinking the steel feed pipe into the design depth by using high-power vibrating hammer as the driving force, filling the gravel into the hopper and silo, and then pulling out the feed pipe through vibration.

Gravel pile is suitable for compaction of loose sand, silt, plain filled soil and mixed filled soil foundation. Gravel pile is mainly used in strengthening weak foundation, strengthening dam side slope, eliminating the liquefaction of liquefied sand, eliminating the collapsibility of collapsible loess, etc.

Shanghai large diameter vibrating immersed tube gravel pile with strong foundation has the following advantages

(1) Large power, fast piling speed, high safety of equipment: our company chooseJB180,JB220Such as large pile frame to ensure the safety of construction, carrying400kw,500kwReinforced electric hammer, to ensure the speed of driving pile, equipped with pressure device to ensure timely discharge of pile bottom, pile diameter is generallyφ800to1000mm, can reach1200mm, pile length can be reached40mThe above.

(2) Wide range of application: our gravel pile equipment can not only be applied to land foundation treatment, but also can be applied to water foundation treatment, to meet more and more water foundation treatment projects.

(3) Intelligent control system: Our company's gravel pile construction equipment has introduced intelligent control system, which can monitor the key parameters such as vibration hammer current, casing insertion and lifting speed in real time, and display the pile deepth-current-time curve in real time, so as to realize intelligent construction of gravel pile and ensure the accuracy of construction parameters.
