Description
Technical field
The utility model relates to a kind of steel guardrail, is specifically related to the device that a kind of steel guardrail is increased.
Background technology
Highway in China construction experienced by a upsurge in construction phase, through operation for many years, progressively the maintenance interval is entered in the highway a period of time from now on of building in advance, in the medium-capital overhauling process of road surface, when carrying out overlay surface layer on original road surface or increasing road surface thickness, can road surface elevation be increased, cause the crashproof height of original corrugated beam barrier not meet code requirement.
Conventional guard rail increases the defect that method exists: in provincial highway overhaul process, part way causes road surface elevation to increase because road structure changes, the crashproof height of road surface elevation increase way of escape side wave ellbeam guardrail can not meet the requirement of " highway traffic safety facilities design specification " (JTG D081-2006), needs to carry out increasing process.If original guardrail is all more renewed guardrail, cost is too high, also causes very large waste.The method pulled out column and again squeeze into mainly is adopted in overhaul process in the past, the construction process of the method is: first wave-shaped beam guardrail board, obstruction block, upright post cap are removed, then with extractor, column is extracted, the unified distance moving 1m forward or backward reinstalls wave-shaped beam guardrail board, obstruction block, upright post cap after again squeezing into.But in implementation process, find that the method exists following shortcoming: a) column part column when pulling out and again squeeze into is impaired; B) in stone matter excavation section and rock-filling embankment section, former column is that coagulating cement earth foundation cannot be extracted; C) after column is transferred to, form roadbed cavity in median strip or earth shoulder, rainwater infiltrates roadbed and easily destroys subgrade stability; D) column is again squeezed into process and is easily destroyed original communication pipe, especially at cross over-line bridge and central separating belt opening place; E) bridge corrugated beam barrier column needs all to change.Therefore a kind of method that corrugated beam barrier being applicable to common arterial highway increases is developed very necessary.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provide the device that a kind of corrugated beam barrier is increased, after this device can effectively solve paving, corrugated beam barrier setting height(from bottom) relative altitude reduces the safety and economic problems brought, has huge Social and economic benef@.
For solving the problem, the technical scheme that the utility model is taked is: comprise the guardrail board column for supporting guardrail board, this guardrail board column is segmentation structure,
The reserved section that described guardrail board column comprises the buried supporting section in roadbed in bottom and is fixed among supporting section;
Described reserved section side is fixedly connected with guardrail board.
Obstruction block is installed with between described guardrail board and reserved section.
Two end faces of described obstruction block are all processed with the bolt hole be connected with reserved section and guardrail board respectively,
Two end faces of obstruction block are all by being bolted in reserved section and guardrail board of mating with bolt hole.
Described reserved section is by bolt and be fixed in supporting section.
Described reserved section top is provided with cap.
Described guardrail board is corrugated guardrail plate.
Compared with prior art, the utility model has following beneficial effect: the utility model is by becoming segmented by guardrail board column design, supporting section meets setting height(from bottom) first, reserved section is carved among supporting section, increase in process at later stage guardrail, reserved section is risen to and needs height, in new high degree, reserved section is fixed in supporting section, this guardrail board column can provide a supporting role corrugated guardrail plate as common column, conveniently can increase in the guardrail dam heightening works in later stage again, the utility model in use, by promoting, reserved to make the later stage add high cost minimum, and the program has construction soon, less on vehicle pass-through impact, adapt to various roadbed, the situations such as guardrail basis, and not to roadbed and sclerosis curb, sclerosis median strip impacts.Have higher practical value to the maintenance and renovation process of speedway and low-grade highway, this heightening device can be selected according to road surface increased heights and road maintenance scheme.
Further, obstruction block can prevent errant vehicle from mixing resistance function at guardrail board column place, and it is an energy absorbing members, guardrail board can be made to be out of shape gradually after being collided, be conducive to energy absorption, reduces occupant's injures and deaths;
Further, for preventing guardrail board stud cylinder internal water accumulation and etch roadbed and corrosion column, need to install additional cap on column, so namely can the immersion of rain cover, make again column seem attractive in appearance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, reserved section; 2, supporting section; 3, bolt; 4, cap; 5, guardrail board; 6, obstruction block.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details:
See Fig. 1, the guardrail board column comprised for supporting guardrail board 5 of the present utility model, this guardrail board column is segmentation structure, the reserved section 1 that guardrail board column comprises the buried supporting section 2 in roadbed in bottom and is secured by bolts among supporting section 2, reserved section 1 side is fixedly connected with guardrail board 5, and obstruction block 6 is installed with between guardrail board 5 and reserved section 1, two end faces of this obstruction block 6 are all processed with the bolt hole be connected with reserved section 1 and guardrail board 5 respectively, two end faces of obstruction block 6 are all bolted in reserved section 1 and guardrail board 5 by what mate with bolt hole, on reserved section 1 top, cap 4 is installed, this cap 4 can prevent guardrail board stud cylinder internal water accumulation and etch roadbed and corrosion column, need to install cap additional on column, so namely, can the immersion of rain cover, column is made again to seem attractive in appearance.
The utility model fits guardrail board 5 for corrugated guardrail plate.
Using method of the present utility model:
Supporting section 2 is installed to the height needed first when using by the utility model, reserved section 1 is carved among supporting section, increase in process at later stage guardrail, reserved section is risen to and needs height, in new high degree, reserved section 1 is bolted in supporting section 2, after heavy resurfacing, as wave beams height need be regulated, take off cap 4, unload the connecting bolt 3 between guardrail board column and obstruction block 6, take out reserved section 1, adjustment makes guardrail board stem height meet safety standard, fixed by bolt 3 in new high degree and supporting section 2, good and sound cap 4.
