Monolithic covering lid for subway in railway construction, has building auxiliary wall that is extended at underside over its width, and arranged more nearly at terminal end than supporting surface for counter bearing

摘要

#CMT# #/CMT# The covering lid (2) has a building auxiliary wall (7) that is extended at the underside (8) over its width, and arranged more nearly at the terminal end (4) than the supporting surface (5) for counter bearing. The horizontal portion of the lid is led out over the auxiliary wall with respect to the terminal end. The building material is filled in space between transverse slots (21) beside the outer side (9) of auxiliary wall. #CMT# : #/CMT# An independent claim is included for arrangement of covering lid. #CMT#USE : #/CMT# Monolithic covering lid for subway in railway construction. #CMT#ADVANTAGE : #/CMT# Since the building auxiliary wall is extended at underside over its width, and arranged more nearly at terminal end than supporting surface for counter bearing, a complete shield of the region of the transverse slot beside the outer side of the building auxiliary wall is ensured and the formwork state of arrangement can be manufactured. Thus, time and cost are saved. The recovery of the traffic route is possible according to the effected backfilling of building material. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating the state of construction of arrangement of covering lid. 2 : Covering lid 4 : Terminal end 5 : Supporting surface 7 : Building auxiliary wall 8 : Underside of lid 9 : Outer side of auxiliary wall 21 : Transverse slots.
