Construction method of bedding slope steep dip excavation and anchor strengthening structure
A construction method of a bedding slope steep dip excavation and anchor strengthening structure comprises the following steps of 1), determining slope surface elevation and plane positions of a slopecrest and the like which are excavated in a steep dip manner on a bedding slope; 2) constructing pre-stressed anchor rods on the slope above and below the excavated slope crest; 3) constructing framed girder reinforced concrete at the outer ends of the prestressed anchor rods above the excavated slope crest; 4) excavating a steep dip excavated body reinforced by the prestressed anchor rods to theposition of an excavated contour line; 5) constructing framed girder reinforced concrete at the outer ends of the prestressed anchor rods; 6) excavating a bedding excavated body which can be subjected to bedding construction below the excavated slope in a graded manner; 7) constructing prestressed anchor rods in the steep dip excavated body on the inner sides of graded sections; 8) excavating thesteep dip excavated body reinforced by the prestressed anchor rods in the graded sections to the position of the excavated contour line in the graded section; 9) constructing framed girder reinforcedconcrete at the outer ends of the prestressed anchor rods; and 10) repeating the step 6) to the step 9) until construction of the prestressed anchor rods and framed girders on the slopes of all graded sections is completed.
