ABSTRACT:
A ground reforming method comprises a first step for inserting an injection rod into ground to be reformed, which injection rod includes a first conduit and a second conduit surrounding the first conduit, and a first injection nozzle communicated with the first conduit and a second injection nozzle surrounding the first nozzle and communicated with the second conduit; a second step for feeding first component of an instantaneous hardening type hardening material or a slow hardening type hardening material into the first conduit of the injection rod and a second component of the hardening material or compressed gas into the second conduit; and a third step for injecting the first component of the instantaneous hardening type hardening material or the slow hardening type hardening material and the second component or compressed gas at a super high pressure through the first and second nozzles to mix each other with moving back the injection rod from the inserted portion with revolving.
