PROCESS OF ERECTION OF ENCLOSING WALL IN GROUND Russian patent published in 2003 - IPC

FIELD: civil engineering. SUBSTANCE: given process deals with erection of enclosing wall in ground during construction of various structures worked deeper into ground, specifically, soft water-saturated ground, such as tunnels, motor roads, railways in close proximity to standing buildings and structures. Process of erection of enclosing wall in ground provides for erection of enclosing wall in two stages. At first stage solid mass comprising at least two rows of secant ground-and-cement piles is formed. At second stage, after 2-7 days after formation of solid mass drilled cast-in-place piles are erected in it which can be drilled secant and/or drilled tangent and/or standing alone piles or concrete wall of " wall in ground " type. Ground-and-cement piles can be positioned by method of jet technology. EFFECT: prevention of possible deformation of piles and destruction of foundations and bases of structures located in close proximity to newly built object, decreased construction period, reduced dynamic load on buildings standing next to built object. 1 cl
