The invention discloses a three axes agitating
pile construction method capable of assisting in grooving of a reinforced underground diaphragm wall. The construction method is characterized by comprising the following technological steps that a, the range of a reinforced target of three axes agitating piles is determined; b, the reinforcing depth of the three axes agitating piles is determined; c, the distance between an inner reinforcing
pile body and an outer reinforcing
pile body of the three axes agitating piles is determined; d, guide wall construction is conducted according to a construction technique of an ordinary underground diaphragm wall; e, the
slurry proportion is adjusted properly; f, main
quality control points of reinforcement of the three axes agitating piles are determined; g, the stability of a pile
machine is checked; h, the perpendicularity control over a pile frame of the three axes agitating piles is strengthened; i, the
water cement ratio, the stirring time and the
slurry quality are controlled strictly, and the
slurry injection pressure and the slurry injection speed during slurry injection are controlled; and j, the drilling speed and lifting speed of a
drill pipe are controlled strictly. The construction method has the advantages that the technique is mature, construction is easy and convenient, the project quality is safe and reliable, the horizontal displacement and settlement amount of important structures are quite small, the requirements for
economic benefits are met, and smooth implementation of a project is guaranteed.
