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. 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.
(1) powerLarge, fast pile driving speed, high safety of equipment:We 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 application scope:Our gravel pile equipment can not only be applied to land foundation treatment, but also 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 an intelligent control system, which can monitor 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.
The technology of large diameter crushed stone pile has the characteristics of low cost, short construction period, safety and reliability, and has broad market prospects in large-scale reclamation projects.
