PROCESS OF ERECTION OF MULTILEVEL UNDERGROUND STRUCTURE ( VARIANTS ) Russian patent published in 2003 - IPC

FIELD: construction industry, erection of multistory underground structures of various assignment by open-cut method. SUBSTANCE: process in compliance with first variant provides for formation of walls in ground along outline of erected structure, construction of floor on planned surface of ground with thrust fixing of it to walls erected in ground, assembly of bearing structure leaning against walls erected in ground and attachment of jointing suspenders to bearing structure. Process includes development of ground under floor in space limited by walls and stories. Height of each story in erected structure is not less than level of erected structure. Corresponding floor is erected after development of ground on each story except last one. Foundation plate is laid after development of ground of last story. Erection of each floor after development of due story is accompanied by build-up of suspenders through height of story and attachment of proper floor to them. After erection of foundation plate capital columns are erected and floors are attached to them. In correspondence with second variant process provides for erection of walls in ground, construction of floor with reinforcing belt on planned surface of ground, attachment of floor with reinforcing belt to walls erected in ground, installation of sections of capital columns on this floor and building of above-lying floor, installation of inclined members and their attachment to laid floors and formation of space bearing structure by inclined members and floors. Thereafter ground is developed under lowest floor in space limited by walls, stories with height of story not less than height of level of erected structure. Jointing suspenders are attached to space bearing structure in first story, these suspenders are attached in each story except last. EFFECT: reduced labor input and usage of materials for erection of multilevel underground structure under conditions of crowded town development with simultaneous acceleration of erection process thanks to development of ground under floors with increased reliability of thrust support. 10 cl, 4 dwg
