Abstract
The utility model discloses a foreign material invasion rigid protective screen for high-speed railways, which aims to improve anti-impact capacity of the protective screen and reduce foreign material impact capacity. The foreign material invasion rigid protective screen comprises section steel posts distributed at intervals along a line extending direction, the lower portion of each section steel post (10) is fixedly buried inside a soil retaining wall or a foundation under a side slope platform, the section steel posts (10) and upper edges thereof are longitudinally distributed with steel wire ropes (20) at intervals to form a post rope supporting system, two section steel posts (10) located at two ends of the line extending direction are respectively fixedly connected with two ends of each steel wire rope (20), and the other section steel posts (10) are provided with holes for the steel wire ropes (20) to penetrate through.
Description
Technical field
The utility model relates to the protective equipment of high-speed railway, particularly a kind of anti-foreign body intrusion rigidity facility that is arranged at the high-speed railway subgrade face outside.
Background technology
For preventing the impact of foreign matters such as falling rocks,, the protective equipment of anti-foreign body intrusion need be set outside the road bed both sides of high-speed railway to guarantee the bullet train traffic safety.Existing protective equipment roughly has two classes, and a class is that rigidity is blocked grid, structurally is made of spaced apart shaped steel column and the reinforcing bar grid that is fixed thereon, and exists not possess to slow down the shortcoming that foreign matter impacts; Another kind of is the flexible anti protecting wire net, is made of column, cable wire and net, though possess certain foreign matter impact capacity of slowing down, because by drawing anchor line to fix, there is the more weak deficiency of rigidity in its column, its impact resistance is relatively poor.
The utility model content
Technical problem to be solved in the utility model provides the anti-foreign body intrusion rigid protection net of a kind of high-speed railway, has good impact resistance and slows down the foreign matter impact capacity.
The technical scheme that its technical problem that solves the utility model adopts is: high-speed railway of the present utility model is prevented foreign body intrusion rigid protection net, comprise the shaped steel column that road along the line bearing of trend is laid at interval, the bottom of various steel post is embedding to be fixed in the retaining wall or in the basis under the plain stage of slope, it is characterized in that: described shaped steel column and its upper edge longitudinal separation are laid wire rope and are constituted post rope support system, two shaped steel columns that are positioned at circuit bearing of trend two ends are fixedlyed connected with the two ends of each wire rope respectively, then are provided with the hole for steel wire penetrating on all the other shaped steel columns.
For tackling the foreign body intrusion of all size effectively, be linked with gauze wire cloth on the described post rope support system, the perforation size of gauze wire cloth is not more than 50mm * 50mm.
Be further to strengthen the stability and the impact resistance of post rope support system, be set with the shaped steel inclined support bar on described two shaped steel columns that are positioned at circuit bearing of trend two ends.
Slow down the foreign matter impact capacity for further strengthening protective screening, described two shaped steel columns that are positioned at circuit bearing of trend two ends are fixedlyed connected with each wire rope by damper.
The beneficial effects of the utility model are with shaped steel column and wire rope formation post rope support system, to give full play to the rigidity of shaped steel column and the toughness of wire rope, so have good impact resistance and slow down the foreign matter impact capacity; Shaped steel column, wire rope can be selected different specifications and arrangement pitch for use according to anti-foreign matter size of invading, impact energy size etc., have good versatility, can adapt to various circuit environment well.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the structural representation of the anti-foreign body intrusion rigid protection net of the utility model high-speed railway;
Fig. 2 is the lateral view of the anti-foreign body intrusion rigid protection net of the utility model high-speed railway;
Component shown in the figure, toponym and pairing mark: shaped steel column 10, flare section 10a, shaped steel inclined support bar 11, shaped steel transverse supporting rod 12, wire rope 20, damper 21, gauze wire cloth 22.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, high-speed railway of the present utility model is prevented foreign body intrusion rigid protection net, comprises the shaped steel column 10 that road along the line bearing of trend is laid at interval, and the bottom of various steel post 10 is embedding to be fixed in the retaining wall or in the basis under the plain stage of slope.Described shaped steel column 10 is laid wire rope 20 with its upper edge longitudinal separation and is constituted post rope support system, two shaped steel columns 10 that are positioned at circuit bearing of trend two ends are fixedlyed connected with the two ends of each wire rope 20 respectively, then are provided with the hole of passing for wire rope 20 on all the other shaped steel columns 10.Constitute post rope support system with shaped steel column 10 and wire rope 20, give full play to the rigidity of shaped steel column 10 and the toughness of wire rope 20, therefore have good impact resistance and slow down the foreign matter impact capacity, shaped steel column 10, wire rope 20 can be selected different specifications and arrangement pitch for use according to anti-foreign matter size of invading, impact energy size etc., have good versatility, can adapt to various circuit environment well.
With reference to Fig. 2, for tackling the foreign body intrusion of all size effectively, be linked with gauze wire cloth 22 on the described post rope support system, the perforation size of gauze wire cloth 22 is not more than 50mm * 50mm.Gauze wire cloth 22 can be fixed or wire binding is fixed on the wire rope 20 by fastener.Slow down the foreign matter impact capacity for strengthening the rigid protection net, the described two shaped steel columns 10 that are positioned at circuit bearing of trend two ends are fixedlyed connected with wire rope 20 by damper 21.For tackling foreign matter better and preventing that the pedestrian from climbing, the top of described shaped steel column 10 has flare section 10a, makes the top of formed protection facade have corresponding flare angle.
Be to strengthen the stability and the impact resistance of post rope support system, be set with shaped steel inclined support bar 11 on described two shaped steel columns 10 that are positioned at circuit bearing of trend two ends.The upper end of described shaped steel inclined support bar 11 and 10 welding of shaped steel column, the lower end is then embedding be fixed in the retaining wall or plain stage of slope basis down in, the lower end of shaped steel inclined support bar 11 or be fixed in the retaining wall or shaped steel transverse supporting rod 12 that plain stage of slope basis down is interior welds with embedding.
Some principles of the above anti-foreign body intrusion rigid protection net of the utility model high-speed railway that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
