DEVICE FOR ERECTION OF LINING IN SUBSURFACE STRUCTURE FROM MONOLITHIC-PRESSED CONCRETE Russian patent published in 2000 - IPC

Abstract RU 2144617 C1

FIELD: construction engineering. SUBSTANCE: device can be used in construction of tunnels by means of shield driving. Device for erection of lining includes tunnel driving shield with shield hydraulic jacks, pressure ring, and shuttering. Shuttering is made up of interconnected pressing and forming sections, hydraulic cylinders which are connected with pressing section of shuttering and with shield body. Hydraulic jacks of shield are connected with pressure ring. Each hydraulic cylinder is pivotally connected with pressing section and shield body. Lower blade-like part of body base is made flat and is located at acute angle to generating line of base. Rear internal end of tail part of body base is made in the form of toroidal surface. Flat surface of lower blade-like part of body base can be provided with stiffening rib. Application of embodiment of device allows for increasing productive capacity in process of erecting lining of subsurface structure together with improving quality of concrete lining, simplification of design and improving its reliability. EFFECT: higher efficiency. 1 cl, 5 dwg
