Description

Technical Field

[0001] The utility model relates to the technical field of road safety protection guardrails, in particular to a wave-shaped guardrail structure suitable for difficult sections of mountain roads. Background Art

[0002] With the improvement of road conditions, the traffic conditions of group roads have also been greatly improved. Motor vehicles can travel at higher speeds, but higher requirements are also placed on the safety measures set up in the sections of roads near water and cliffs. However, due to terrain restrictions, it is difficult to reserve enough width for the construction of ordinary driven or buried corrugated guardrails. Traditional corrugated guardrails and traffic facilities are generally driven or buried. There are the following difficulties in their construction in difficult sections of mountainous areas: driven corrugated guardrails require a certain width of roadbed to be reserved. One side of the difficult section of mountainous area is adjacent to water and cliffs. Unless the investment is greatly increased, the roadside slope is further excavated or the shoulder retaining wall is constructed, the width required for the driven corrugated guardrail cannot be met; buried corrugated guardrails require the construction of concrete piers. The construction of concrete piers on the cliff side of difficult sections of mountainous areas requires a large amount of concrete. The cliffs of extremely difficult sections are close to vertical, and even concrete piers cannot be constructed. Therefore, for such sections, there is an urgent need for a safety protection facility that does not require additional roadbed width. Utility Model Content

[0029] Example:

[0030] like Figure 1 , Figure 2 As shown, the utility model is a corrugated guardrail structure suitable for difficult sections of mountain roads, comprising a column 1, a corrugated plate 2 and a column base 3, wherein the column 1 is arranged outside a road surface structure 4; the column 1 is vertically arranged on the column base 3, and the column base 3 is buried in the road surface structure 4; the corrugated plate 2 is fixed to the column 1. In this embodiment, the column base 3 is arranged to provide a place for the installation of the column 1 and the corrugated plate 2, and at the same time, the column base 3 is buried in the road surface structure 4, so that the installation construction of the safety protection structure can be completed without increasing the width of the roadbed.

[0031] Specifically, a portion of the column base 3 is buried in the pavement structure 4, another portion of the column base 3 extends outside the pavement structure 4, and the column 1 is vertically arranged on the column base 3 outside the pavement structure 4. The arrangement of the column base 3 can not only effectively fix the column base 3, but also provide an effective place for the installation of the column 1.

[0032] It also includes a transverse tie bar 5, one end of which is buried in the column base 3, and the other end of which extends laterally into the pavement structure 4. In this embodiment, the tensile strength of the transverse tie bar 5 can be used to balance the horizontal impact force when the corrugated guardrail structure is hit. In order to further enhance the tensile strength of the transverse tie bar 5, the end of the transverse tie bar 5 is set as a hook-shaped structure, and the hook-shaped structure faces the side where the column 1 is set. The column base 3 is connected to a plurality of transverse tie bars 5, and the plurality of transverse tie bars 5 are buried in the column base 3 at equal intervals horizontally. At the same time, the horizontal tensile strength is also improved by setting a plurality of transverse tie bars 5.

[0033] It also includes a vertical anchor rod 6, one end of which passes through the column base 3 and is pulled and connected to the surface of the column base 3; the other end of the vertical anchor rod 6 extends vertically downward into the roadbed structure 7. In this embodiment, the column base 3 can be effectively anchored on the roadbed structure 7 through the vertical anchor rod 6 to ensure that the column base 3 will not tilt up when it is hit. At the same time, the inner structure 4 made of concrete plays a weight-bearing role to assist in resisting the tendency of the column base 3 to tilt up when it is hit; and the shear resistance of the vertical anchor rod 6 can also offset part of the horizontal impact force. Specifically, it also includes an anchor rod pressure plate 8, which is arranged on the surface of the column base 3, the top end of the vertical anchor rod 6 passes through the anchor rod pressure plate 8, and the nut arranged at the top end of the vertical anchor rod 6 is pressed and fixed to the anchor rod pressure plate 8. The matching relationship between the anchor rod pressure plate 8 and the vertical anchor rod 6 can more effectively achieve the anchoring effect of the column base 3.

[0034] It also includes a support link 9, which is tilted on the column base 3, and the support link 9 is tilted toward the column 1 and connected to the column 1. In this embodiment, the support link 9 forms a triangular structure with the column 1 and the column base 3, so that the rigidity of the overall structure can be enhanced. Specifically, in order to enhance the stability and connection strength of the connection between the structures, the column 1, the column base 3 and the support link 9 are an integrally formed structure or the column 1, the column base 3 and the support link 9 are welded into a whole.

[0035] The column base 3 is a semi-elliptical plate structure, and the wide side of the column base 3 is buried in the pavement structure 4, and the narrow side of the column base 3 extends to the outside of the pavement structure 4. In this embodiment, the column base 3 with a semi-elliptical plate structure can not only save materials, but also can stably and effectively reduce the tendency of the column base 3 to tilt by utilizing its specific structure.

[0036] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
