METHOD OF CONSTRUCTING WALL IN GROUND FOR PROTECTING FOUNDATION OF BUILDING Russian patent published in 1994 - IPC

FIELD: construction. SUBSTANCE: 'walls within ground' are built on both side of foundation to be protected. To do this one drives pipes having side flat connecting members and open ends into the ground. As the pipe is driven one cleans space of the pipe and forms advancing space under the pipe for decreasing drag. In driving next pipe the ground, which is adjacent to the connecting members, falls down to the space provided under the previous one. After driving pipes wells are drilled up to the level of bottom end of the pipes and the pipes are filled with concrete. The wells are positioned between axes of the pipes from the side opposite to the foundation. EFFECT: simplified method. 2 cl, 5 dwg
