Detailed Description
The invention will be further elucidated with reference to an embodiment in the drawing.
The tunnel rapid danger-removing reinforcing and supporting structure comprises a lining 1, a W-shaped steel belt 2, a longitudinal steel plate 3 and an overlap steel plate 4, wherein the W-shaped steel belt 2 is reinforced along the circumferential direction of the lining 1, the longitudinal steel plate 3 is longitudinally arranged and is connected with the W-shaped steel belt 2 through the overlap steel plate 4, grouting anchor rods 5 are connected between the W-shaped steel belt 2 and the lining 1, and anchor bolts 6 are connected between the longitudinal steel plate 3 and the overlap steel plate 4 and the lining 1. Adopt slip casting stock 5 to connect W type steel band 2 and overlap joint steel sheet 4 and fix on lining cutting 1 in the structure, effectively fix W type steel band 2 so that when full play its high strength, high bending resistance section modulus, form bearing structure to the rock mass of lining cutting 1 rear side. Vertical steel sheet 3 is connected with W shaped steel area 2 and fixes on lining cutting 1 through crab-bolt 6 with overlap joint steel sheet 4, effectively vertically reinforces W shaped steel area 2, has formed an effectual whole reinforced structure.
The lining 1 is provided with a slot 11, the lap steel plate 4 is embedded in the slot 11, and the longitudinal steel plate 3 is in contact with the surface of the lining 1 in a laminating way.
