A cement deep mixing ship pile frame system and pile forming method

Abstract

The invention belongs to the technical field of overwater cement stirring, and relates to a pile frame system and a pile forming method, in particular to a cement deep mixing pile frame system and the pile forming method. The cement deep mixing pile frame system comprises pile frames and a pile frame bracket which is fixed to a ship body; the pile frames comprise two groups, respectively, a first pile frame and a second pile frame; the top of the first pile frame is hinged to the top of the pile frame bracket through a short hinge shaft; the bottom end of the first pile frame is connected with a pile frame base which is fixed to the ship body; the top of the second pile frame is hinged to the top of the pile frame bracket through a long hinge shaft and can slide along the long hinge shaft; a lower hinge seat at the bottom end of the second pile frame is in a sliding groove form, is buckled on a pile frame sliding seat which is fixed to the ship body and is connected with the pile frame sliding seat through bolts; after the bolts are detached, the lower hinge seat can slide along the pile frame sliding seat. The system and the method can form a plurality of piles at one time and can also perform separated operation, and are wide in engineering application range, energy-saving and high-efficiency; the pile frame is translated and operated safely and reliably, and is high in practicability; new construction equipment is provided for marine foundation reinforcement engineering; the system and the method have obvious economic and social benefits.

Description

technical field [0001] The invention relates to a pile frame system and a pile forming method, belonging to the technical field of cement mixing on water, in particular to a pile frame system and a pile forming method of a cement deep mixing ship. Background technique [0002] At present, with the expansion of my country's port construction scale and the development of new port sites, the investment in offshore engineering is increasing, especially in offshore foundation reinforcement projects, such as artificial island submarine foundation reinforcement, pier foundation foundation reinforcement, quay wall wharf foundation reinforcement, revetment And reinforcement of breakwater foundation, etc. [0003] The cement deep mixing reinforcement method is an ideal method for underwater foundation treatment, and has been verified by a large number of actual projects at home and abroad. However, the supporting equipment of domestic cement deep mixing ships is backward, especially t...

AI Technical Summary

Problems solved by technology

[0005] The present invention mainly solves the technical problems existing in the prior art that the area of ​​a single pile pile is small, the foundation treatment efficiency is low, the treatment depth is shallow, the energy consumption is high, and the requirements for high speed, high efficiency and energy saving of new construction cannot be met, and it provides A cement deep mixing ship pile frame system and pile forming method
