Abstract
The utility model discloses an electricity protection tent crossing a railway line. The electricity protection tent crossing railway line comprises a plurality of reinforced concrete foundations arranged on the two sides of a railway track at equal intervals, the top of each reinforced concrete foundation is provided with a pipe column, and a wind cross is arranged between two adjacent pipe column on the same side of the railway track. Longitudinal beams are welded to the tops of the pipe columns in the direction of the railway line, a beam located between two pipe columns is welded to the tops of the longitudinal beams in the direction perpendicular to the direction of the railway line, insulation electricity protection isolation layers are laid at the tops of the beams, and each insulation electricity protection isolation layer is formed by square wood, a bamboo plywood, an insulation plate and an asphaltic felt water-proof layer. On the basis of an anti-smashing function, an electricity protection function is added, the electricity protection tent crossing the railway line ensures safety of normal construction of a bridge crossing a railway line on one hand, and ensures normal operation of a the railway line on the other hand, overcomes the cross effect, ensures normal construction and traffic order, and ensures life and property security.
Description
Technical field
The utility model relates to a kind of anti-electric canopy, specifically, relates to a kind of anti-electric canopy across railway line.
Background technology
When current highway in China and rail track crossed construction, how avoiding cross influence is the most important thing.All can there be power line railway top, exists great potential safety hazard in the time that conductive body approaches power line.Fall and have unavoidably foreign material in construction of the highway process, the power line to railway top and the normal operation of train all have a great impact.
Utility model content
To be solved in the utility model is that highway bridge is across in construction of railways, anti-falling stop thing damages high-voltage line or affects the technical problem of the normal operation of railway, a kind of anti-electric canopy across railway line is provided, continuous beam is sealed to protection across railway region top, while preventing beam cast-in-place construction, fall thing, the people that falls jeopardizes contact net and driving.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of anti-electric canopy across railway line, comprise multiple reinforced concrete foundations that are equidistantly arranged in railroad track both sides, each described reinforced concrete foundation top is provided with tubing string, between adjacent two described tubing strings of railroad track homonymy, be provided with shearing support, described tubing string top is welded with longeron along line direction, described longeron top is welded with the crossbeam between two described tubing strings perpendicular to line direction, the anti-electricity isolated layer of insulation is laid at described crossbeam top, the anti-electricity isolated layer of described insulation is from the bottom to top successively by the lumps of wood, bamboo offset plate, insulating slab, asphaltic felt waterproofing course forms.
Described reinforced concrete foundation end face absolute altitude flushes with railway shoulder.
The beneficial effects of the utility model are:
The utility model across the crossover sites of rail track, has increased electricity-preventing function possessing on anti-basis of pounding for highway bridge, the impact of the power line that has completely cut off railway top on surrounding.Ensure on the one hand the safety across railway line bridge normal construction, effectively completely cut off the impact of power line on top highway structure, ensure on the other hand the normal current of railway line, prevent the destruction of pendant thing to power line, guarantee that railway is normally open to traffic every day, overcome cross influence, eliminated potential safety hazard, ensure normal construction and traffic order, guaranteed the security of the lives and property.

In figure: 1, reinforced concrete foundation; 2, tubing string; 3, shearing support; 4, longeron; 5, crossbeam; 6, the lumps of wood;
7, bamboo offset plate; 8, insulating slab; 9, asphaltic felt waterproofing course; 10, railroad track.
Detailed description of the invention
For further understanding content of the present utility model, feature and effect, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in figures 1 and 3, the present embodiment discloses a kind of anti-electric canopy across railway line, and anti-electric canopy is along railway direction layout, and agent structure adopts shaped steel welding assembled, and the anti-electricity isolated layer of insulation is laid on agent structure top.
According to field condition, anti-electric canopy protection length is that 36m, width are 10m, highly are 10m.Shown in Fig. 4, anti-electric canopy is established 14 reinforced concrete foundations 1, is respectively arranged with 7 in railroad track 10 both sides, and the reinforced concrete foundation 1 of each side is equidistantly arranged.Reinforced concrete foundation 1 physical dimension arranges respectively 1.0 × 1.0 × 1.0m according to design elevation, adopts C30 steel bar concrete, and its end face absolute altitude flushes with railway shoulder.The crab-bolt of pre-buried 4 Φ 30 of each reinforced concrete foundation 1 is used for connecting tubing string 2.
Each reinforced concrete foundation 1 top is provided with the steel tubing string 2 of a φ 270mm by crab-bolt.Railroad track homonymy is provided with along 2 of adjacent two tubing strings of line direction that [the shearing support that 100 channel-section steels are made, to add stiff stability.
As shown in Figure 2, the anti-electricity isolated layer that insulate is made up of the lumps of wood 6, bamboo offset plate 7, insulating slab 8, asphaltic felt waterproofing course 9 from the bottom to top successively.The anti-electricity isolated layer that insulate can effectively be controlled the impact of power line near people it and things.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing from the scope situation that the utility model aim and claim protect; can also make the concrete conversion of a lot of forms, within these all belong to protection domain of the present utility model.
