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) Large pile frame, high power: the gravel pile frame of Shanghai strong foundation can carry power400/500kWThe high energy vibration hammer, gravel pile into pile diameter up to1200mm, pile length can exceed30mSo that the effective diameter and depth of gravel pile have a great breakthrough.
(2) Saving time: Under the same replacement rate, the new process can greatly reduce the total number of piles, so as to effectively save time.
(3Reliable discharge: in some soft soil or liquefiable silt soil, due to the pressure of water and soil on the bottom of the pile, the valve of the pipe boot can not be opened, and the discharge is difficult. In this respect, Shanghai Strong Foundation has accumulated rich experience, and can improve the equipment according to the actual situation to ensure smooth discharge.
(4) Feeding method is safe: the traditional feeding method is to use steel rope suspension to lift the hopper, because the hopper is not fixed, there are great safety risks. The free sloshing of the hopper also greatly affects the feeding efficiency and delays the construction period. In ORDER TO SOLVE THIS PROBLEM, THE GRAVEL PILE EQUIPMENT of Shanghai STRONG FOUNDATION adopts the forward track feeding method to fix the lifting hopper on the front track, which eliminates the hidden danger of safety and improves the safety, and also improves the construction efficiency.
(5Intelligent control system: Intelligent control system is introduced into the gravel pile construction equipment of Shanghai strong foundation, which can monitor the key parameters such as vibration hammer current, cutting quantity, immersed pipe and drawing 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.
(6Wide range of application: the gravel pile equipment of Shanghai strong foundation can not only be applied to land foundation treatment, but also can be applied to water foundation treatment (using Shanghai strong foundation thousand ton engineering ship as carrier), to meet more and more water foundation treatment projects.
