DEVICE FOR POSITIONING immerse TUNNEL SECTIONS

摘要

FIELD: construction.;SUBSTANCE: device to position a submerged tunnel section comprises a frame with two substantially vertically arranged support stands, upper ends of which are connected substantially horizontally with an arranged beam. The frame is made with the possibility of sliding so that its support stands pass in external direction from two opposite lateral sides of the tunnel section, and its beam is arranged above the tunnel section vault. The frame is equipped with suspension facilities, where a tunnel section may be suspended. Lower ends of support stands are made as capable of vertical displacement relative to the submerged tunnel section, and each support stand comprises clamp elements designed for interaction with the specified opposite lateral sides of the tunnel section and made with the possibility of adjustment substantially in the plane restricted with support stands and the beam of the frame.;EFFECT: improved safety in production of works, provision of proper positioning of the tunnel section, reduced labour intensiveness and material intensity.;20 cl, 8 dwg
