Abstract
The utility model discloses a double-layer flexible shed tunnel, which comprises two-sidewall bases and a plurality of arched girders located between the two-sidewall bases. The ,arched girders are formed by bending H-shaped steel; the heights of the adjacent girders are different; shear beams are evenly distributed between the adjacent girders; both ends of the shear beam and webs of the two girders are in bolted connection; the upper surface and the lower surface of the arched girder are respectively covered by a layer of flexible protective mesh, and the flexible protective meshes are all in bolted connection with flanges of the adjacent girders. The double-layer flexible shed tunnel can prevent stones with a certain of impact force, which fall from high positions, so as to effectively protect passing vehicles and pedestrians; the arched girders are connected by the shear beams, so the mechanical property and the stability are good; the two layers of flexible protecting meshes are adopted, so the energy dissipation role and the force transmission role are good; the heights of the arched girders are different to present a certain of artistic effect, so the arched girders per se can form a landscape, meanwhile, the arched girders can collect the falling stones into the depressed position so as to facilitates cleaning.
Description
Technical field
The utility model relates to the road construction field, is specifically related to be used to protect the flexible hangar tunnel of a kind of bilayer 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.Though existing hangar tunnel structure adopts arched girder to do support; but the arched girder height is identical; the profile dullness; easily make the people cause visual fatigue; utilize crossbeam to connect between arched girder, it is easily bending damage when bearing the falling rocks impact load, and the hangar tunnel structure can not be played a very good protection; and adopt the individual layer protective screening, protective capacities a little less than.
The utility model content
The purpose of this utility model provides a kind of addressing the above problem, and is both artistic and practical, and anti-falling rocks impact capacity is strong, and be difficult for bending and damage, and the good double-deck flexible hangar tunnel of protective capacities.
The technical solution of the utility model is: the flexible hangar tunnel of a kind of bilayer, 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 shaped 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, and the upper and lower surface of arched girder respectively coats one deck flexible anti protecting wire net, and the equal bolt of described flexible anti protecting wire net is connected on the edge of a wing of adjacent arched girder.
As preferably: equidistant arrangement between described arched girder.
As preferably: alternate arched girder height is identical.
The beneficial effects of the utility model are: owing to adopt shear beam to connect between arched girder of the present utility model; therefore when it is subjected to external impacts; energy dissipating and power transmission effect are very good; shear beam is connected with the arched girder bolt, is easy to the upper and lower surface of arched girder is installed; all coat one deck flexible anti protecting wire net; be double-deck protective screening structure, more can bear bigger impact force, the less falling rocks of particle diameter is played the double shielding effect; arched girder height difference; after covering the flexible anti protecting wire net, the depression in the middle of it can be collected handstone, is convenient to cleaning; height is straggly between arched girder; have certain artistic effect, making himself can become view one, for highway construction has increased new watching focus.

Fig. 1 is the utility model front view;
Fig. 2 is the utility model lateral view;
Fig. 3 is a connection diagram of the present utility model.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises both sides surbase 1 and is positioned at the arched girder 2 of several equidistant arrangements of 1 of both sides surbase, described arched girder 2 is formed by the bending of H shaped steel, and adjacent arched girder 2 is highly different, alternate arched girder 2 is highly identical, 2 of adjacent arched girders are provided with equally distributed shear beam 3, the bolts at two ends of described shear beam 3 is connected on the web of two arched girders 2, the upper and lower surface of arched girder 2 respectively coats one deck flexible anti protecting wire net 4, and described flexible anti protecting wire net 4 equal bolts are connected on the edge of a wing of adjacent arched girder 2.
When shear beam 3 is subjected to external impacts; energy dissipating and power transmission effect are very good; not yielding bending; shear beam 3 is connected with arched girder 2 bolts; be easy to install; the upper and lower surface of arched girder 2 all coats one deck flexible anti protecting wire net 4, promptly double-deck protective screening structure; more can bear bigger impact force; the less falling rocks of particle diameter is played the double shielding effect, and arched girder 2 is highly different, cover flexible anti protecting wire net 4 after; depression in the middle of it can be collected handstone; be convenient to cleaning, 2 height of arched girder are straggly, have certain artistic effect; make and 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.
Claims (3)
1. flexible hangar tunnel of bilayer, comprise the both sides surbase and be positioned at several arched girders between the surbase of both sides, it is characterized in that: described arched girder is formed by the bending of H shaped 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, and the upper and lower surface of arched girder respectively coats one deck flexible anti protecting wire net, and the equal bolt of described flexible anti protecting wire net is connected on the edge of a wing of adjacent arched girder.
