Abstract
The utility model discloses a multilayer flexible shed tunnel, comprising two side wall bases and a plurality of arched girders arranged between the two side wall bases, wherein the arched girders are formed by bent H-shaped steel; furthermore, the adjacent arched girders have different heights; shear beams are uniformly distributed between the adjacent arched girders; the upper surface and the lower surface of the arched girders are covered by a layer of flexible protective net respectively; the arched girder is also provided with an additional beam that is also formed by bent H-shaped steel; a wing edge at one side of the additional beam is fixedly attached to the wind edge of the corresponding arched girder; a layer of flexible protective net is arranged on the additional girder; and the flexible protective net is connected with the wing edge at the other side of the additional beam by bolts. The multilayer flexible shed tunnel can protect the fallen stones and can effectively protect the safety of the vehicles and pedestrians; the arched girders are connected by the shear beams and have good mechanics performance and stability; three layers of flexible protective nets can effectively prevent the crushed stone grains from falling off; and the arched girders have different heights, thus having certain artistic effects.
Description
Technical field
The utility model relates to the road construction field, is specifically related to be used to protect a kind of layer flexible hangar tunnel of pavement of road.
Background technology
Crag falling rocks disease to road adopts measures such as a retaining, protective screening or construction hangar tunnel to administer usually, building hangar tunnel is the hangar tunnel of building in the falling rocks district across the road surface, utilize the protective screening structure at hangar tunnel top to bear, alleviate the impact load of falling rocks, avoid falling rocks directly to impact the destruction that road pavement and related facility cause, and guarantee traffic safety.Existing hangar tunnel is by constituting with arched girder between the abutment wall pedestal, adopt crossbeam to link to each other between adjacent arched girder, the high-altitude falling rocks, be easy to compressive deformation, coat one deck flexible anti protecting wire net on the crossbeam, anti-rubble and other short grained effect are bad, and, arched girder height unanimity, the profile dullness easily makes the people cause visual fatigue.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of good looking appearance, energy dissipating and power transmission to make the layer flexible hangar tunnel of making good use of, and it can bear bigger impact force, and its protective capacities is obviously strengthened.
The technical solution of the utility model is: a kind of layer flexible hangar tunnel, comprise the both sides surbase and be positioned at several arched girders between the surbase of both sides, described arched girder is formed by the bending of H shape steel, and adjacent arched girder height difference, be provided with equally distributed shear beam between adjacent arched girder, the bolts at two ends of described shear beam is connected on the web of two arched girders, the upper and lower surface of arched girder respectively covers one deck flexible anti protecting wire net, described flexible anti protecting wire net bolt is connected on the edge of a wing of adjacent arched girder, also be provided with an additional beam on the arched girder, described additional beam is also formed by the bending of H shape steel, and a side wing edge of additional beam is fitted fixing with the edge of a wing of corresponding arched girder, be equipped with one deck flexible anti protecting wire net on the additional beam, described flexible anti protecting wire net bolt is connected on the opposite side edge of a wing of additional beam.
As preferably: equidistant arrangement between described arched girder.
As preferably: alternate arched girder height is identical.
The beneficial effects of the utility model are: adopt shear beam to connect between arched girder, mechanical property and good stability, pressurized is not yielding, and be equipped with the flexible anti protecting wire net on the upper and lower surface of arched girder, then the relative one deck flexible anti of protection effect protecting wire net is better, additional beam on the arched girder, also supported one deck flexible anti protecting wire net, make the quantity of flexible anti protecting wire net reach three layers, the protection energy level is bigger, protective action to the small particle diameter falling rocks is very outstanding, and shear beam is connected with the arched girder bolt with the flexible anti protecting wire net, is easy to construction and installation, and is highly different between arched girder, in picturesque disorder, have certain artistic effect, making himself can become view one, for highway construction has increased new watching focus, this structure can embody the construction theory of " people-oriented; ecological, environmental protective; save resource; sustainable development " preferably, also follows " being suitable for; economy; safety simultaneously, attractive in appearance " design principles.
