Description

technical field [0001] The invention belongs to the field of pile foundation construction equipment, and in particular relates to an intelligent construction system of a large-diameter deep-layer mixing composite pile and a use method thereof. Background technique [0002] Cement-soil deep mixing pile is a method for strengthening soft soil foundation. It uses cement as a curing agent, and through a special mixing machine and a slurry pump, the soft soil and curing agent are forced to mix and mix in the depth of the foundation. A series of physical and chemical reactions between the agent and the soft soil harden the soft soil into a composite foundation with integrity, water stability and high foundation bearing capacity. The mixer has a core tube with blades on its head. When the mixer rotates, the cement slurry is sprayed out through the spray port at the end of the core pipe, and stirred and mixed with the soil loosened by the rotating blades to form a cement reinforcem...

Problems solved by technology

[0003] At present, traditional pile drivers are mainly used for deep mixing piles, but the existing deep mixing pile drivers have the following problems: First, the construction efficiency is greatly affected by human factors, and the mechanical operation level and overall quality of workers affect the construction efficiency. Subjective factors lead to The construction error is difficult to control; the second is that the construction efficiency is low, and the drilling speed of the deep mixer in the dense sand layer is slow. If it encounters a harder soil layer, the construction of the mixing pile may not continue, which seriously affects the construction progress; the third is the construction cost. High, equipment damage is serious, and the wear of the drill bit is serious when the deep-layer mixing pile machine drills in the dense sand layer
