Abstract

The invention discloses a novel vibroflotation pile construction method, equipment and a control method. Compared with a conventional construction method, the vibroflotation pile construction method is characterized in that in pore-forming and compacting processes by a vibroflotation device, matched with water and gas linkage, the construction method is achieved by combining water and gas linkage,a unique water spraying mode and reasonable control of feedwater quantity and gas feeding quantity in stages. The construction efficiency is improved obviously while the construction quality is guaranteed. An automatic control system and method control a constant pressure water supply system, action of the vibroflotation device, variable frequency control of a water pump, depth measurement, filler metering, compactness monitoring and the like in the vibroflotation process accurately. The construction tendencies are mastered in real time, and scientific construction and effective management are realized.

Description

technical field [0001] The invention relates to a new vibrating pile construction method and a control system. The invention belongs to the technical field of vibrating foundation reinforcement treatment. Background technique [0002] With the increasing scale of infrastructure engineering construction, the requirements for foundation treatment are getting higher and higher, especially when building various buildings on bad foundations, it is necessary to improve the bad foundations according to various geological conditions , in order to meet the requirements of building various buildings on this basis. [0003] In foundation treatment engineering, the construction method of vibro-pile is more and more widely used. The so-called vibrating pile construction method is to vibrate several holes on the reinforced foundation through vibrating equipment, fill the holes with gravel and other filling materials, and then compact them to form a vertical pile composed of crushed ston...
