Abstract
The utility model relates to a rockfall-resistant reinforced concrete shed-tunnel structure arranged on a bridge-tunnel connection section. A protecting structure arranged on the bridge-tunnel connection section is high in construction difficulty, proof in protection performance and low in structure safety. The rockfall-resistant reinforced concrete shed-tunnel structure arranged on the bridge-tunnel connection section is provided with pile foundations, bearing platforms, reinforced concrete pier columns and longitudinal beams from bottom to top. One end of each longitudinal beam is erected on the top of the corresponding einforced concrete pier column and the other end of each longitudinal beam is anchored into a spread foundation of the tunnel end. A reinforced concrete lining structure which covers a bridge and is of an arc shape is arranged on the tops of the longitudinal beams. Side walls of the reinforced concrete lining structure are provided with pressure-relief vents. The reinforced concrete lining structure is coated with an elastic protecting layer. Cross beams are transversely arranged between the reinforced concrete pier columns and pull rods are longitudinally arranged between the reinforced concrete pier columns. The pull rods are anchored into bedrock of the tunnel end. The rockfall-resistant reinforced concrete shed-tunnel structure arranged on the bridge-tunnel connection section is good in stability, high in safety, good in durability, small in later-period operation maintenance workload, low in cost, and nearly free of influence on vehicle running. The pressure-relief vents can reduce the dead load of the structure, and the natural lighting function and the ventilation function are achieved at the same time.
Description
Technical field
the utility model belongs to traffic engineering technical field, is specifically related to the connected location of a kind of bridge tunnel rock-fall proof steel concrete shed hole structure.
Background technology
In mountain area, build high-speed railway, the general coombe in the connected location of bridge tunnel is grown, and sloping bank is steep, and falling rocks is grown, and construction condition is poor, and falling rocks has a strong impact on traffic safety.Traditional safeguard structure, site operation difficulty is large, and barrier propterty is poor, and safety of structure is not high.Location, Borland Line for Passenger Transportation Qinling Mountain Areas tunnel portal is mostly " V " type cheuch, and the natural grade on earth's surface, hole is that 60 ° of-80 ° of falling rocks are grown, and the connected phenomenon of bridge tunnel is general.
Summary of the invention
The purpose of this utility model is to provide the connected location of a kind of bridge tunnel rock-fall proof steel concrete shed hole structure, adapts to cheuch location operating mode, prevents that falling rocks from tumbling on circuit or train, and guarantees structure inherently safe.
The technical scheme that the utility model adopts is:
The connected location of a tunnel rock-fall proof steel concrete shed hole structure, is characterized in that:
Be provided with pile foundation, cushion cap, Reinforced Concrete Pier Column and longeron from bottom to top, longeron one end is erected at Reinforced Concrete Pier Column top, and the other end anchors in the expansion basis of tunnel end;
Longeron top arranges outer bridge reinforced concrete lining layer structure top, arch that covers on.
Between described Reinforced Concrete Pier Column, be horizontally arranged with crossbeam, be vertically arranged with pull bar, pull bar anchors in the basement rock of tunnel end by the anchor pole of its termination.
Described Reinforced Concrete Pier Column top is provided with the bent cap that cross-sectional area is greater than Reinforced Concrete Pier Column, is provided with pinner and bearing in the groove at bent cap top, and one end of longeron is erected on the bearing at Reinforced Concrete Pier Column top.
The both sides abutment wall of described reinforced concrete lining layer structure is provided with vent.
Described reinforced concrete lining layer structure is covered with elastic protective layer outward.
The utlity model has following advantage:
The utility model stability is good, safe, excellent in durability, and later stage operation maintenance workload is little, and cost is low, on driving a vehicle almost without impact; Vent can alleviate dead load, has natural lighting, ventilation function simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model cross section.
Fig. 2 is the utility model hangar tunnel side view.
In figure, 1-reinforced concrete lining layer structure, 2-vent, 3-longeron, 4-expands basis, 5-bearing, 6-pinner, 7-bent cap, 8-Reinforced Concrete Pier Column, 9-pull bar, 10-crossbeam, 11-anchor pole, 12-cushion cap, 13-pile foundation, profile in 14-, 15-elastic protective layer.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
The connected location of a kind of bridge tunnel rock-fall proof steel concrete shed hole structure that the utility model is related, being positioned at the connected location of bridge tunnel arranges, bottom is provided with pile foundation 13, pile foundation 13 tops arrange cushion cap 12, cushion cap 12 tops arrange Reinforced Concrete Pier Column 8,8 of Reinforced Concrete Pier Columns are horizontally arranged with crossbeam 10, are vertically arranged with pull bar 9, and pull bar 9 anchors in the basement rock of tunnel end by the anchor pole 11 of its termination.Reinforced Concrete Pier Column 8 tops are provided with the bent cap 7 that cross-sectional area is greater than Reinforced Concrete Pier Column 8, are provided with pinner 6 and bearing 5 in the groove at bent cap 7 tops.After substructure construction completes, on 4, the expansion basis of bearing 5 and tunnel end, set up longeron 3, one end of longeron 3 is erected on the bearing 5 at Reinforced Concrete Pier Column 8 tops, and the other end anchors in the expansion basis 4 of tunnel end.Longeron 3 tops arrange and cover on bridge reinforced concrete lining layer structure 1 top, arch outward, and need and longeron 3 are fixed, form a kind of by the structural system of external environment isolation relative to environment.The both sides abutment wall of reinforced concrete lining layer structure 1 is provided with vent 2, can alleviate dead load, has natural lighting, ventilation function simultaneously.Reinforced concrete lining layer structure 1 is outer is covered with elastic protective layer 15, and elastic protective layer can adopt resilient rubbber cushion, protection shed hole structure.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
