Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
A central anti-collision guardrail structure comprises a guardrail 1 and a foundation 2, wherein reinforcing steel bars 4 are arranged inside the guardrail 1 and the foundation 2, and the guardrail 1 and the foundation 2 are integrally cast through concrete; the guardrail 1 comprises two parts with the same structure, and is arranged at two ends of the foundation 2.
In order to solve the problem that the quality of the guardrail is easily influenced, part of facilities cannot be constructed synchronously with the guardrail, excavation construction needs to be carried out after the construction of the guardrail is finished. The utility model discloses still including setting up the reservation structure, the reservation structure sets up between the two parts of guardrail 1.
The reserved structure comprises a reserved cable pipeline 21, a flange steel bar 22, a reserved flange 23 and a concrete envelope 25; the reserved flange 23 is arranged on the upper surface of the foundation 2 and used for mounting a street lamp rod piece 24 or a sign rod piece; the reserved flange 23 is provided with flange steel bars 22, and the lower parts of the flange steel bars 22 are inserted into and fixed in the foundation 2; a concrete envelope 25 is arranged on the reserved flange 23; the upper end of the reserved cable duct 21 extends out of the reserved flange 23, and the lower end of the reserved cable duct 21 extends into the foundation 2 and extends outwards.
In the field of the existing highway central anti-collision guardrail, the guardrail 1 and the foundation 2 are placed by re-excavating the positions after a road is paved, and further the top standard heights of the guardrails are inconsistent. In order to solve the problems, the utility model also comprises a road structure 3, wherein the road structure 3 comprises a subbase layer 34, a lower base layer 33, an upper base layer 32 and an asphalt surface layer 31 which are arranged from bottom to top in sequence; the foundation 2 is placed over the lower base layer 33 with the sides of the foundation 2 being surrounded by the upper base layer 32 and the asphalt overlay 31.
In a specific embodiment, a drainage hole 13 is formed in the bottom of the guardrail 1, and the drainage hole 13 is used for draining accumulated water in the guardrail 1 outwards.
In one embodiment, the flanges 23 are provided with stiffening ribs 231 for supporting the street light pole members 24.
After the construction and maintenance of the road sub-base layer 34 and the lower base layer 33 are completed, the elevation of the road is basically stable, and the guard rails and the foundation are placed above the lower base layer 34, so that the top elevation of the guard rails can be ensured to be consistent, and the size of the guard rails can be controlled easily; then, reinforcing steel bars can be bound, a template can be supported, the guardrail and the foundation are integrally poured together, and the integrity of the guardrail can be ensured; finally, implementing the upper base course 32 and the asphalt surface course 31 of the road; the middle of the guardrail can be filled with greening soil, and the bottom of the guardrail 1 is provided with a reserved drain hole 13, so that accumulated water in rainwater can be conveniently discharged.
