The problem of low anchorage system safety coefficient.
In order to solve techniques described above problem, Analysis of Suspension Bridges ' Anchorage anchor described in the utility model, including adapter
Pull bar, Anchor Cable Anchorage, prestress anchorage cable, anchor tie plate concrete and sealing off and covering anchorage concrete, described adapter pull bar, Anchor Cable Anchorage and pre-
Stress anchor cable is sequentially connected with, and the periphery of described Anchor Cable Anchorage arranges a plurality of parallel anchor bar, the end of described Anchor Cable Anchorage
Arranging reinforced mesh under multilamellar anchor, described anchor bar passes in reinforced mesh from described anchor, described Anchor Cable Anchorage, anchoring steel
During under muscle and anchor, reinforced mesh is embedded in described anchor tie plate concrete and sealing off and covering anchorage concrete, described adapter pull bar reinforcing bar from anchor
Mesh sheet passes.
As preferably, under anchor described in the utility model, reinforced mesh is set to 3 ~ 6 layers.
Further, the two ends of anchor bar described in the utility model are outwards rolled over；Described anchor bar is diameter 20 ~ 32 millimeters
Reinforcing bar.
Analysis of Suspension Bridges ' Anchorage anchor described in the utility model, the periphery of its Anchor Cable Anchorage arranges a plurality of anchoring steel parallel
Muscle, the end of described Anchor Cable Anchorage arranges reinforced mesh under multilamellar anchor, and under described anchor bar and anchor, reinforced mesh is embedded in anchor in advance
In arm-tie concrete and sealing off and covering anchorage concrete, and surround Anchor Cable Anchorage, can be that adapter pull bar provides interim when construction
Support；Under anchor, reinforced mesh dispersibles stress under anchorage, it is to avoid stress is concentrated.
The beneficial effects of the utility model: owing to employing structure described above, this utility model has simple in construction, executes
The advantages such as work is easy, practical, effect is notable, when in rock anchor, certain prestress anchorage cable lost efficacy, the main push-towing rope thread of its correspondence
Power be first transferred to anchor, by anchor tie plate concrete, power is disperseed to other prestress anchorage cable, it is ensured that main push-towing rope thread
Anchoring, if a rock anchor failure of cable can be prevented effectively from, the situation that the main push-towing rope thread of its correspondence is the most ineffective, carry to greatest extent
The durability of high Analysis of Suspension Bridges ' Anchorage, it is ensured that bridge security.

Detailed description of the invention
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Analysis of Suspension Bridges ' Anchorage anchor described in the utility model, including adapter pull bar 1, Anchor Cable Anchorage 2, prestress anchorage cable
3, anchor tie plate concrete 4 and sealing off and covering anchorage concrete 5, described adapter pull bar 1, Anchor Cable Anchorage 2 and prestress anchorage cable 3 be sequentially connected with,
The periphery of described Anchor Cable Anchorage 2 arranges a plurality of parallel anchor bar 6, and the end of described Anchor Cable Anchorage 2 arranges steel under multilamellar anchor
Muscle mesh sheet 7, described anchor bar 6 passes in reinforced mesh 7 from described anchor, under described Anchor Cable Anchorage 2, anchor bar 6 and anchor
Reinforced mesh 7 is embedded in described anchor tie plate concrete 4 and sealing off and covering anchorage concrete 5, described adapter pull bar 1 reinforced mesh from anchor
Pass in 7.
As preferably, under anchor described in the utility model, reinforced mesh 7 is set to 3 ~ 6 layers.
Further, the two ends of anchor bar 6 described in the utility model are outwards rolled over；Described anchor bar 6 is diameter 20 ~ 32 milli
The reinforcing bar of rice.
Embodiment one: the middle part of Anchor Cable Anchorage 2 described in the utility model arranges a macropore, each aperture in both sides, greatly
Hole is prestress anchorage cable hole 10, and for the connection of prestress anchorage cable 3 with Anchor Cable Anchorage 2, aperture is adapter tie rod hole 11, is used for
