Specific embodiment

For ensure framed bent set up, run and demolishing process in safety, it is clear that the danger stone of scar 1 is subjected to system before construction Reason prevents the danger stone in subsequent construction from coming off, jeopardizes lower part construction personnel, equipment safety.

With reference to attached drawing.Framed bent sets up structure under MODEL OVER COMPLEX TOPOGRAPHY provided by the utility model, including wall-connecting piece 2, stands Bar 3, leger 4, small cross bar 5 and flexible drawing anchor line 6.

The small cross bar is laid on above leger, and small cross bar is not in direct contact with scar；

Described flexible drawing anchor line one end is fixedly connected with wall-connecting piece, and the other end is fixedly connected with the host node of framed bent.

Wall-connecting piece 2 is set：Wall-connecting piece 2 uses joint bar.2 joint bar of framed bent wall-connecting piece under MODEL OVER COMPLEX TOPOGRAPHY, which uses, to be not less than The spiral of φ 25mm, joint bar are 45 ~ 90 ° with the generally requirement of 1 angle of scar, and unapproachable for part, wall-connecting piece 2 is inserted Muscle tilts upwards as possible, so that it is guaranteed that wall-connecting piece 2 is by shear stress；2 joint bar of wall-connecting piece length enters rock and is not less than not less than 1.0m 0.6m, exposed 0.4m；Wall-connecting piece 2 is laid according to array pitch between design, for landform local crowning or hangs rock mass position by the feet, Wall-connecting piece 2 should be encrypted, an array pitch cannot be less than two steps two across.

Upright bar 3 is set：For the framed bent under MODEL OVER COMPLEX TOPOGRAPHY, 3 bottom of upright bar should set pedestal or backing plate 7, ensure vertical 3 stability under loading of bar；Two sections of neighbouring upright bars 3 should use overlap joint, the lap of splice be not less than 1m, and be no less than three fasteners 8 are fixedly connected.

Leger 4 is set：Leger 4 preferably uses the steel pipe of 6m, to reduce overlap joint, length direction of the leger 6 along framed bent Setting, leger 6 and upright bar 3 are connected with fastener 8；Two sections of adjacent legers 6 of left and right do not use docking generally using overlapping, The lap of splice is not less than 1m, and is fixedly connected with no less than three fasteners 8.

Small cross bar 5 is set：Small cross bar 5 is laid on 4 top of leger, is fixed with fastener, and small cross bar 5 uses and leger 4 Identical tube material；Small cross bar 5 should not be in direct contact with scar 1, and the two standoff distance is generally in 0.2m or so.

Flexibility draws anchor line 6 to set：At landform local crowning position, top or/and lower section should set flexible drawing anchor line 6, To increase the stability of framed bent；It is flexible that anchor line 6 is drawn to be fixed using Φ 16mm steel cables with framed bent host node 100, draw anchor line 6 and level It draws anchor line 6 that rope card is used to be fixedly connected into becket bridle 60 into 30 ~ 45o of updip, is socketed respectively with wall-connecting piece and host node, rope blocks in face Fixed often end no less than 3.It is each to draw anchor line 6 secured using Φ 16mm steel cables and scar 1 wall-connecting piece, 2 drawknots.

The host node is leger 4 and the connecting portion of upright bar 3.
