C.G.S CONSTRUCTION METHOD CAPABLE OF SEISMIC RETROFIT AND QUALITY CONTROL

摘要

A. C.G.S construction method capable of seismic retrofit and quality control is provided. The method includes steps of inserted an injection pipe in the ground, the injection pipe provided for injecting a grout into the ground; injecting the grout into the ground through the inserted injection pipe, the grout being injected in predetermined quantities per unit time under an injection pressure that is a predetermined static pressure; measuring a discharge pressure of the injected grout; adjusting, according to the change in measurement value of the measured discharge pressure, at least one or more among the injection pressure of the grout in the injecting stage, and the unit time per which predetermined quantities of the grout are injected; and changing the depth at which the injection pipe is inserted in the ground after the injection of the grout is completed.
