Abstract
The utility model discloses a rigid-flexible concrete anti-collision guardrail, and relates to road traffic safety facilities. The rigid-flexible concrete anti-collision guardrail is composed of a road bed, a cement stabilized base, a pavement, a reinforced concrete panel, a steel pipe and the like. According to the concrete anti-collision guardrail with a steel pipe structure, the lower end of the steel pipe is arranged in the road bed and the cement stabilized base, and the upper end of the steel pipe is poured with the reinforced concrete panel together. As the steel pipe structure is arranged in the concrete anti-collision guardrail, the concrete anti-collision guardrail organically combines the rigid characteristic of a reinforced concrete anti-collision guardrail and the flexible characteristic of a waveform anti-collision guardrail to make the best of the both anti-collision guardrails and combine rigidity and flexibility, the safety performance of the anti-collision guardrail is increased, and the degree of damage of vehicle collision is also reduced. The concrete anti-collision guardrail is practical, safe and economic and can effectively ensure the safety of highway operation and reduce the loss of traffic accidents.
Description
Technical field
The utility model relates to a kind of highway subgrade steel concrete anticollision barrier, refers in particular to a kind of have rigidity and the flexible steel concrete anticollision barrier in conjunction with feature.
Background technology
Anticollision barrier is a kind of traffic safety facilities that is widely used in highway and bridge, and it is divided into the steel concrete anticollision barrier of rigidity and flexible waveform anticollision barrier usually.The rigidity anticollision barrier is generally made by Reinforced Concrete Materials, it is mainly used on bridge, strength and stiffness are very large, during Vehicular impact rigidity anticollision barrier, anticollision barrier can not be subjected to displacement and make vehicle produce buffering, therefore vehicle generally can not fall below bridge floor, but can cause damaged vehicle serious.The flexible protection guardrail generally is comprised of steel pipe pile and corrugated sheet, is mainly used on roadbed, and strength and stiffness are generally little, and when dilly clashes into, anticollision barrier can be subjected to displacement and make vehicle produce buffering, therefore can reduce the damaged vehicle degree; But, when large heavy vehicle clashes into, the flexible protection guardrail, by badly damaged, is difficult to prevent that vehicle from falling to road surface or below bridge floor when having an accident, and will cause heavy losses.Above-mentioned two kinds of anticollision barriers respectively have pluses and minuses, for the flexible characteristic of the rigidity characteristic by the steel concrete anticollision barrier and waveform anticollision barrier combines, learn from other's strong points to offset one's weaknesses, only have to adopt and there is rigidity and the flexible steel concrete anticollision barrier in conjunction with feature, could both improve the security performance of anticollision barrier, reduce again the extent of damage of Vehicular impact.

The accompanying drawing explanation
Fig. 1 is facade structures schematic diagram of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
The specific embodiment
Below will to the utility model embodiment, elaborate again by above-mentioned accompanying drawing.
As shown in Figure 1 and Figure 2,1. roadbed, 2. cement stabilized base course, 3. road surface, 4. steel concrete panel, 5. steel pipe, 6. laterally spilled water hole, 7. side slope, 8. partitioning slot.
Hard and soft property concrete anti-collision guard bar, it is a kind of traffic safety facilities, mainly comprise highway roadbed 1, be laid on the cement stabilized base course 2 on roadbed and be laid on the road surface 3 on cement stabilized base course, on the cement stabilized base course 2 of pavement edge, steel concrete panel 4 is set again.
Described roadbed 1 is to fill to the requirement height by design, and possesses the supporting capacity of regulation, and this shoulder is provided with side slope 7, and side slope is necessarily processed, so that roadbed 1 can reach overall stability; Described cement stabilized base course 2 has some strength and rigidity, mainly as the basis of steel concrete panel 4, bears vertical load and horizontal loading simultaneously; Described road surface 3 is load-carrying members of vehicle pass-through, and these 3 surfaces, road surface are provided with along the cross fall of roadbed 1 edge tilt, to facilitate the ponding rapid drainage on road surface.
Squeeze into steel pipe 5 in described roadbed 1 and cement stabilized base course 2, this steel pipe is the steel hollow section, its specification quantity is determined according to road quality classification and highway subgrade geological conditions, general external diameter 130～150mm, wall thickness 4～5mm, length 2～3mm, the length that steel pipe 5 lower ends are squeezed in roadbed 1 and cement stabilized base course 2 is 1 ~ 2m; Steel pipe 5 upper ends are stretched out cement stabilized base course 2 and are exposed, this upper end is by assembling reinforcement and concreting, thereby form the steel concrete panel 4 of building one with steel pipe 5 upper ends, steel pipe 5 upper end length are 1/2 ~ 2/3 of steel concrete panel 4 height, mainly bear the vertical force of steel concrete panel 4 and the horizontal force action of Vehicular impact.
4 of described steel concrete panels are on cement stabilized base course 2, and be set to along the segmented steel concrete panel 4 of road direction extension, every section steel concrete panel 4 all has independent collision prevention function, and its specification is definite according to road quality classification, and length is generally 3 ~ 4m; Be equipped with 3 ~ 4 steel pipes in every section steel concrete panel 4, the partitioning slot 8 of reserved 1 ~ 2cm between every adjacent two sections steel concrete panels 4, the yielding materials such as the interior all filled bitumens of each partitioning slot, to reduce by every section frictional resistance between steel concrete panel 4 and to increase aesthetic measure.The Main Function of partitioning slot 8 is: one, make to reduce integral rigidity after 4 segmentations of steel concrete panel, increase flexibility, and have independent collision prevention function; Two, reduce thermal (temperature difference) stress, guaranteed the quality of steel concrete panel 4; Three, avoid roadbed 1 differential settlement to bring the settlement crack of steel concrete panel 4.
The bottom of described steel concrete panel 4 is provided with a plurality of horizontal spilled water holes 6 that tilt at an angle to roadbed 1 edge, each horizontal spilled water hole 6 is all transverse drainage facilities of setting separated by a distance between steel concrete panel 4 and cement stabilized base course 2, the aperture of each horizontal spilled water hole 6 is 3 ~ 5cm, and the spacing between adjacent two horizontal spilled water holes 6 is 1.5 ~ 2m.The road surface 3 ponding mainly road surface 3 by having cross fall, to roadbed 1 edge-diffusion, then drain into roadbed side slope 7 by a plurality of horizontal spilled water hole 6 of steel concrete panel 4 bottoms fast.
This concrete anti-collision guard bar combines the rigid function of steel concrete panel 4 and the flexibility function of steel pipe 5, learns from other's strong points to offset one's weaknesses, and tempers toughness with gentleness.When Vehicular impact steel concrete panel 4, steel concrete panel 4 is easy deformed damaged unlike corrugated sheet; Simultaneously, due to the flexibility effect of steel pipe 5, make steel pipe after being impacted 5 produce elastic deformations, but and allow every section steel concrete panel 4 generating horizontal displacements, thereby make accident vehicle produce cushioning effect, to reduce vehicle and occupant's damage; When removing vehicle impact, as steel pipe 5 distortion, within elastic range, steel concrete panel 4 can arrive original straight state by immediate recovery again.
Embodiment described in the utility model only is not used in restriction scope of the present utility model for the utility model is described.Should be understood that in addition, after having read content described in the utility model, those skilled in the art can make various changes or modifications the utility model, these equivalent form of values fall within the application's appended claims limited range equally.
