The liner tube includes a housing and an internal shaft placed inside the housing and coupled to inside the housing via a locking mechanism. Subsequent to insertion into the soil, the internal shaft is unlocked from the housing and removed therefrom. Thereafter, a grooved pipe is inserted inside the housing using the inserting device. Subsequent to the grooved pipe insertion into the housing, the housing is removed from the loose granular soil using a mechanical excavator and a space between the loose granular soil and the grooved pipe is filled with a filling material.
