Abstract
The utility model relates to a double-peak type concrete guard rail. The utility model is characterized in that one end of the guard rail is provided with a main peak 1, and the other end is provided with a secondary peak 2. The utility model has the advantages that the structure is simple; the new concept of initiative leading to the rebound of a runaway vehicle is adopted; the utility model is particularly suitable for being installed on an expressway.
Description
The utility model belongs to safety barrier, especially for the concrete guardrail on the speedway.
Guardrail is indispensable safety device on the speedway, and it mainly acts on exactly for preventing that errant vehicle from running off highway or swarming into the track, opposite, and protection is from member's safety and avoid second accident.Unimodal formula concrete guardrail (Fig. 1) is a kind of in the at present most widely used road safety guard.Be mainly used in highway median strip and bridge etc.Its maximum characteristics are that floor space is little.Present unimodal concrete guardrail mainly is to slow down the bump degree by the gradient design of meeting the face of hitting.There is a very big problem in this design: be exactly that errant vehicle is easy to be sprung into other track, very easily cause second accident like this when vehicle flowrate is big.
The purpose of this utility model is to propose a kind of double-peak type concrete guardrail, and this guardrail carries out the control of active guiding to the resilience of errant vehicle.
Main feature of the present utility model is that the end at guardrail has a main crest 1, at the other end one attached crest 2 is arranged.
The utility model is simple in structure, has adopted the initiatively notion of guiding is carried out in the resilience of errant vehicle, is particularly suitable for using safely on the speedway.
Accompanying drawing 2 is the double-peak type concrete guardrail sectional schematic diagram.
1 is main crest among the figure, and 2 is attached crest, and 3 are the guiding ditch
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
By accompanying drawing 2 as can be seen, double-peak type concrete guardrail mainly contains two concrete crests to be formed, and establishes guardrail and has introduced notion to the ACTIVE CONTROL of errant vehicle resilience.The face of hitting of meeting of this guardrail is changed traditional unimodal design, and main crest (1) is used for controlling errant vehicle and does not cross guardrail; Attached crest (2) is used for errant vehicle is carried out the resilience guiding.When errant vehicle and guardrail bumped against, wheel at first contacted with attached crest 2 and bumps, and made errant vehicle begin to turn to when crossing attached crest 2.Vehicle body is parallel with guardrail substantially when errant vehicle bumps with main crest 1 like this, thereby plays the effect that slows down impact, makes the errant vehicle single wheel enter two peak-to-peak guiding ditches.Because the existence of attached crest, this guardrail has also reduced the possibility that errant vehicle topples.Simultaneously, main crest 1 and attached crest 2 all have certain effect that slows down impact.
Distance between main crest 1 and the attached crest 2 is 18cm-45cm, and α 1 is 45 °-90 °, and α 2 is 60 °-90 °, and its concrete parameter can be adjusted as required.
Claims (2)
1, double-peak type concrete guardrail has main crest (1) to it is characterized by at the other end at the one end one attached crest (2) is arranged.
2, the distance that it is characterized by between main crest (1) and the attached crest (2) by the described guardrail of claim 1 is 18CM-45CM, and α 1 is 45 °-90 °, and α 2 is 60 °-90 °.
