Abstract
The utility model relates to a highway eccentric obstruct-proof block waveform girder guard rail heightening apparatus, which comprises an obstruct-proof block, the positions on the obstruct-proof block with certain distances away from the upper part and the lower part of the central line are provided with bolt holes respectively, the certain distance is one-half of the road surface increasing height. According to the scheme, the anti-collision height of the waveform girder guard rail can be improved by changing the new eccentric obstruct-proof block, the connecting bolt hole of the obstruct-proof block and an upright post is moved downwards for one-half of the increasing height from the center, the connecting bolt hole of the waveform girder and the obstruct-proof block is moved upward for one-half of the increasing height, after the manufacturing is completed, the old obstruct-proof block is dismounted, the new eccentric obstruct-proof block is changed only. The technical scheme has advantages of low fabrication cost, fast construction, and small influence for vehicle traffic, can be adapted to various cases such as foundation and guard rail foundation, and can not influence the foundation, rigidified road shoulder and rigidified central separating band.
Description
Technical field
The utility model relates to a kind of freeway guardrail device, especially a kind of speedway when maintenance asphalt concrete pavement that is applicable to is lower than 10cm, and corresponding corrugated beam barrier column need improve the eccentric obstruction block corrugated beam barrier of the following speedway of 10cm heightening device.
Background technology
China's expressway construction has experienced a high-tide period at present, and through operation for many years, the speedway of Jian Sheing progressively enters the overhaul phase in a period of time from now in advance, and the road surface medium-capital overhauling will become vital task of speedway maintenance management person.In the medium-capital overhauling process of road surface, when overlaying surface layer on original road surface or increasing in the work progress of road surface thickness, can cause the road surface elevation to increase, cause the crashproof height of original corrugated beam barrier not meet design requirement.
Beijing-Shanghai Expressway Linyi section is the part of national trunk line Beijing to the Shanghai highway, be open to the traffic in 1999, be open to traffic over 10 years, reasons such as, overload big because of the traffic volume is serious, diseases such as a large amount of transverse cracks and more depression, check crack, rut, purt slurry have appearred in the part road surface, and Shandong Province transportation department carries out large repairs this road section surface, repaiies in express highway pavement in the design scheme, often adopt the asphalt concrete pavement that overlays 4-5 centimetre of one deck, the corresponding road surface elevation improves 4-5 centimetre; Or employing overlays two-layer 8-10 centimetre asphalt concrete pavement altogether, the corresponding road surface elevation improves 8-10 centimetre, cause the crashproof height of corrugated beam barrier to reduce 4-10 centimetre, the crashproof height that the road surface elevation increases corresponding median strip, back and trackside corrugated beam barrier can not satisfy the design specifications requirement, need increase processing.If original guardrail is all more renewed guardrail, cost is too high, also causes very big waste.Mainly adopt the method that column is squeezed into again of pulling out in overhaul process in the past.The construction process of this method is: at first corrugated beam barrier plate, obstruction block, column cap are removed, with extractor column is extracted then, after unified position of moving 1 meter is forward or backward squeezed into again, reinstall corrugated beam barrier plate, obstruction block, column cap.But find that in implementation process there is following shortcoming in this method: 1, column part column when pulling out and squeeze into again is impaired; 2, in stone matter excavation highway section and the former column of rock-filling embankment section can't extract for the coagulating cement earth foundation; 3, after column is transferred to, form the roadbed cavity in the median strip, rainwater infiltrates roadbed and destroys subgrade stability easily.4, column is squeezed into process again and is destroyed original communication pipe easily, especially at last overline bridge and the median opening place of striding.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to use, cost is low, construction is fast, and is less to the vehicle pass-through influence, adapt to various roadbeds, guardrail basis, is applicable to that the road surface elevation increases below the 10cm, respective waveforms beam fence upright need improve below the 10cm, and not to roadbed and sclerosis curb, the eccentric obstruction block corrugated beam barrier of the speedway that impacts of sclerosis median strip heightening device.
For achieving the above object, the utility model adopts following technical proposals:
The eccentric obstruction block corrugated beam barrier of a kind of speedway heightening device comprises obstruction block, is respectively equipped with bolt hole in a distance up and down apart from its horizontal center line on the described obstruction block, and described certain distance increases 1/2nd of height for the road surface elevation.
This programme adopts the method that more renews eccentric obstruction block to improve the crashproof height of corrugated beam barrier, the connecting bolt hole of obstruction block and column is moved down 1/2nd of needs increase height by the center, the connecting bolt hole of wave beams and obstruction block moved up by the center needs to increase 1/2nd of height, after completing, old obstruction block is removed, and the eccentric obstruction block that more renews gets final product.
Obstruction block has the errant vehicle of preventing and mixes the resistance function at the column place, and it is an energy-absorbing member, can make guardrail distortion gradually after being collided, and helps energy absorption, reduces occupant's injures and deaths.Two connecting bolt holes on the obstruction block are played and are connected column and waveform beam action, and the off-centre of bolt hole does not influence obstruction block collision rear defence and mixes resistance and endergonic effect.
The technical program cost is low, and construction is fast, and is less to the vehicle pass-through influence, adapt to situations such as various roadbeds, guardrail basis, and roadbed and sclerosis curb, sclerosis median strip do not impacted.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein 1. wave beams, 2. obstruction block, 3. bolt, 4. column.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, be respectively equipped with bolt hole in a distance up and down apart from its horizontal center line on the obstruction block 2, described certain distance increases 1/2nd of height for the road surface elevation, and obstruction block 2 is connected with column 4 with wave beams 1 with bolt hole by bolt 3 respectively.
This programme adopts the method that more renews eccentric obstruction block to improve the crashproof height of corrugated beam barrier, the connecting bolt hole of obstruction block 2 and column 4 is moved down 1/2nd of needs increase height by the center, the connecting bolt hole of wave beams 1 and obstruction block 2 moved up by the center needs to increase 1/2nd of height, after completing, old obstruction block is removed, and the eccentric obstruction block that more renews gets final product.
With the roadside barrier is example, analyzes relatively the update all guardrail, extracts that column is squeezed into mode again, the setting-up eccentricity obstruction block adds Senior Three kind scheme cost, calculates by every kilometer cost:
According to last table relatively, the technical program cost is low, and construction is fast, and is less to the vehicle pass-through influence, adapt to situations such as various roadbeds, guardrail basis, and roadbed and sclerosis curb, sclerosis median strip do not impacted.
