The basal surface of curved plate arranges the intermediate structure of multiple tubulose, the two ends of described intermediate structure connect two arc-shaped partitions respectively in the mode of continuous welding, there is provided horizontal support force to steel lining assembly, make steel lining structure side form complete even curface simultaneously, evenly bear the active force that tunnel machine applies.The particular location that intermediate structure is arranged and number are determined according to the design of steel lining structural entity.
The junction of steel lining assembly and adjacent steel lining cutting assembly is provided with weather strip, and described weather strip is made up of compressible elastomeric material, closes the gap of steel lining inter-module, improves the water proofing property of steel lining structure.
General tunnel machine comprises excavating gear, conveyer belt, hydraulic lifting apparatus.In constructing tunnel process, tunnel machine is pushed ahead, the earth that excavating gear is excavated transports to the rear of tunnel machine through conveyer belt, steel lining assembling components is formed steel lining structure by hydraulic lifting apparatus on tunnel, the existing steel lining structure of steel lining anatomical connectivity of new composition, and be fixedly connected with screw bolt and nut.
As preferably, the width of described arc-shaped partition is 0.6cm ~ 1.2cm.The width of end bulkheads is 0.6cm ~ 1.2cm.
As preferably, the mode by continuous welding between framework with curved plate is connected, and without any gap and space between curved plate and framework, ensures the water proofing property of steel lining structure.
The utility model structure is simple, and easy for installation, the tunnel machines such as shield machine can be coordinated to use together, and compared with traditional concrete slab and wooden frame, sealing and water proofing property are more excellent, and forms a smooth plane and apply reaction force in tunnel machine.
