Investigation of existing city water, power, gas and INDEX 132 underground watercourses. ii. Investigation of ground water level and direction of flow. Finding whether the location planned to be injected with Alofix-MC is above or below water level. iii. Investigation of soil and its density, and of the borders between layers. iv. Test of water permeability of the soil. 3UHYHQWKHDYLQJ Soil Injection Steps for injection of the Alofix-MC consist of: „ Driving (drilling) the injection nozzle down to the planned depth. „ Commencement of injection with the mixed material. „ Controlled withdrawal of the nozzle, at set distances, at pre-determined time intervals. „ Repetition of the preceding process with injection points spaced to overlap injected soil / Alofix-MC columns. $OR¿0& „ Preventing settlement of roads and embankments to be constructed on weak ground „ Preventing heaving and boiling embankments inside cofferdams „ Stabilisation of soil in zones susceptible to landslides „ Remedying and preventing differential settlement of oil tanks „ Fixation and water sealing in fractured zone during tunnel construction „ Curtain grouting for dams and embankments „ Ensuring leak-tightness of retention dykes around oil tanks „ Stabilisation and sealing of work faces in shield tunnelling and pipe insertion work „ Water sealing of joints on water and sewerage mains „ Water sealing of tunnel walls „ Water sealing of dam bases „ Water sealing of reservoir bases „ Underground oil storage facilities „ Preventing seepage or river embankments „ Preventing seepage of embankments on polder dykes „ Preventing seepage of soil in reclaimed land „ Preventing liquefaction of sandy soil ,QFUHDVHEHDULQJ VWUHQJWK (QVXUHDLUWLJKWQHVV 6HDOZDWHU 3UHYHQWVHHSDJH $OOHYLDWHVRLOSUHVVXUH
