The anchor slab of the support tube tail end passes through work clip sheet for the steel strand anchoring stress.
The head end of the sealing drum is wire sub-panel, and the wire sub-panel will be arranged with the steel of the small pillar of PE by sealing ring
Twisted wire sealing.
The utility model has the beneficial effects that
The utility model anticorrosion structure is simple and reliable, carries out anti-corrosion to anchor head steel strand wires, work clip sheet using anti-corrosion material
Processing, needs multiple preservative treatment, an anti-corrosion constant feast during avoiding stay cable replacing.Anti-corrosion material good fluidity,
All-pervasive, volume is not shunk after solidification, and resistance to compression, tensile strength are high, and caking property is good, is bonded to one with anchorage, sealing effect
Good, no moisture, can extend suspension cable service life at ageing-resistant reachable decades very well, great popularization.
The technical solution of the utility model is further illustrated with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model anticorrosion structure.
Fig. 2, Fig. 3 are the different step schematic diagram of the utility model anti-corrosion method respectively.
Fig. 4 is the grouter schematic diagram that the utility model anti-corrosion method uses.
Specific embodiment
See Fig. 1, the anticorrosion structure of suspension cable anchor head steel strand wires provided by the utility model, including several Cable Stayed Steel twisted wires
A, sealing drum h, connection that on the steel strand wires a and head and the tail both ends separate the steel strand wires a passed through by root are set in simultaneously
It fixes the sealing drum h and sets the support tube z of adjusting nut m, is fixed on support tube z tail end for anchoring Cable Stayed Steel twisted wire
Anchor slab c and intermediate plate b, the shield s for covering the end of the steel strand wires a and main body concrete are tightly connected with the anchor slab c
(steel construction) consolidation is integrally set in outside the support tube z and end is equipped with the cable guide pipe g of suspension cable anchor plate d, the support
Cylinder z is supported on the suspension cable anchor plate d of the cable guide pipe g by the nut m, adjustable described by rotating nuts m
Anchor slab c(anchor point) and the rope suspension cable anchor plate d between axial distance；The sealing drum h, support tube z and shield s
It is inside separately filled with anti-corrosion material t, anti-corrosion material t is epoxy binder modified using " Gu Te nation " --- JN-M structure potting compound
(pressure injection steel bonding glue)；The steel strand wires a is anchored stress by work clip sheet b by the anchor slab c, and the shield is close by steel strand wires
Envelope；The head end of the sealing drum h is wire sub-panel f, and the wire sub-panel f will be arranged with the steel of the small pillar e of PE by sealing ring
Twisted wire a sealing.
When the utility model is used, construction is followed the steps below:
Step 1: after each component installation of anticorrosion structure, completing Cable Stayed Steel twisted wire a installation, cable tension, pass through rotation
The axial distance that turn nut m is adjusted between anchor slab (anchor point) the c and suspension cable anchor plate d meets design requirement, examines
Whether the filament plate f that checks the mark, which seals, does not leak anti-corrosion material t, if having the gap must first take measures to block, girder end anchor head and Sarasota
The gap of Inner bolt head lower curtate position work clip sheet b proboscis rifle foam-injection glue, is then pushed down with locking plate (not drawing)；The anchor slab
C is provided with injected hole i, and injected hole i is towards low direction when installation, as shown in Figure 2.
Step 2: interior madjack pipe q in the sealing drum h is protruded by injected hole i setting, and injected hole i installation with
The mud jacking mouth valve k of the interior madjack pipe q connection.
Step 3: anti-corrosion material t is injected through mud jacking mouth valve k and interior madjack pipe q by the support tube using air pressure grouter
Full entire space is filled in z and sealing drum h, is solidified to anti-corrosion material, mud jacking mouth valve of dismantling, as shown in Figure 3.
The grouter is as shown in figure 4, include setting the air pressure tank 110 of fastening bolt 104 and with seal groove and sealing strip 103
