Document Type and Number:
WIPO Patent Application WO/2000/077307
Kind Code:
A1
Abstract:
Mounted on a car body (1) provided with a running body (2) are a mixer (3), a material soil hopper (8), a material soil conveyor (7), a solid soil improving agent supply device (9), an improved-soil conveyor (10), and a soil improving agent supply device consisting of a liquid supply means (11), a liquid tank (12) and a liquid spraying means (13). The liquid spraying means (13) is mounted near the charge inlet of the mixer (3) to supply a solid soil improving agent and a liquid soil improving agent onto a material soil conveyed by the material soil conveyor (7). Therefore, cement and water are supplied to the material soil to regulate its water content ratio and mix the material soil with cement, whereby a solid and strong improved soil can be formed with a progress of cement hydration. Accordingly the mobile soil improving machine is suitably used for a CSG method.
