Box steel plate is welded on billet with a thickness of 2-4mm, and box surface of steel plate is welded with several pegs, with
Increase the connection with concrete cover.
Prestress anchorage cable diameter is identical as the diameter of billet centre bore, arch steel plate centre bore.
A kind of construction method of shock-absorbing type high slope prestress anchorage cable of the utility model, including following installation steps:
1) it drills in branch armour layer predetermined position, borehole cleaning；
2) it is put into prestress anchorage cable in the borehole, fills mortar；
3) when mortar strength reaches the 70% of design value, gunite concrete forms concrete topping, in concrete topping
Other end steel strand wires are passed through billet centre bore, arch steel plate centre bore, arch steel plate are placed in steel by upper installation billet
On backing plate, prestressed stretch-draw is carried out to steel strand wires and is anchored on arch steel plate with anchor head；
4) box steel plate is covered into the outside in arch steel plate and anchor head, and be welded on billet, box steel plate outer surface
Gunite concrete protective layer；
5) it is completed to first of anchor cable construction, repeats above step and complete lower one of anchor cable construction.
The utility model beneficial effect outstanding is:
(1) the utility model plays shock insulation and damping energy consumption by adding arch steel plate member in supporting construction surface layer
Effect, prevents supporting construction under geological process, and anchor rope breakage occurs for supporting construction or anchor head bursts apart and waits brittle breaks, leads to side
Slope collapses, and causes serious consequence.
(2) arch steel plate can be according to design requirement difference, and seismic behavior is different, using the identical bow of one or more curvature
Shape steel plate is combined with each other.
(3) the utility model arch steel plate elasticity modulus is relatively large, is adapted to large-tonnage high slope prestress anchorage cable
Supporting.
(4) the utility model box steel plate provides space for arch steel plate deformed, and one layer of coagulation is poured outside box steel plate
Soil plays protection supporting role.
