METHOD OF CONSTRUCTION OF MINE SHAFT FROM MONOLITHIC PRESSED CONCRETE Russian patent published in 2001 - IPC

Abstract RU 2171378 C1

FIELD: underground construction; applicable in construction of mine shafts with embedded members and various types of equipment located in them. SUBSTANCE: method includes excavation of ground in face zone, installation of sliding forms with conical bell, supply of concrete mix to space beyond the forms; concreting of section of mine shaft with formation of steps on internal walls of shaft and subsequent advance of forms. After each cycle of concreting, forms members with shaping cylindrical shell and conical bell are installed. Length of bell conical part is larger than length of conical part of bell of previous member of forms. EFFECT: simplified technology of construction of mine shafts with internal cylindrical step-shaped walls. 5 dwg
