摘要
A compaction grouting system (“C.G.S”) construction method capable of seismic retrofit and quality control is provided. An injection pipe is inserted in the ground to an insertion depth and is provided for injecting a grout into the ground at the insertion depth. The grout is injected in predetermined quantities per unit time under an injection pressure that is a predetermined static pressure. A discharge pressure of the grout being injected is measured. At least one or more, among the injection pressure at which the grout is being injected and the unit time per which predetermined quantities of the grout are injected, is adjusted, according to the change in the measurement value of the discharge pressure. The insertion depth at which the injection pipe is inserted in the ground is changed after the injection of the grout is completed.
