Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings.
[0030] refer to Figure 1 ~ Figure 3 , an improved column delineator, the column delineator is composed of a cylinder and a reflector, the cylinder is the structure carrier of the reflector, and the reflector has traffic guiding function. In order to reduce structural damage and damage caused by vehicle collision and road shoulder instability, the following measures are taken to optimize the structure of the column delineator recommended by the current code:
[0031] a. Enlargement of cylinder section. Scaled up to 1.25 times, from 120mm×100mm×120mm recommended by the current specification to 150mm×125mm×150mm. Appropriately enlarging the column can beneficially enhance the traffic guiding ability and strengthen the overall rigidity of the column.
[0032] b. Column material strengthening. It is prefabricated with high-strength and high-elasticity synthetic resin (...

The invention discloses an improved column-type delineator. The improved column-type delineator comprises a cylinder, a reflector and a build-in structure, the cylinder is a structural carrier of thereflector, and the reflector has a traffic inducing effect. The cylinder is pre-formed by adopting high strength and high elasticity synthetic resin , and the cross section of the cylinder is a circular triangle; the build-in structure is a fastening part reserved in a hole of a foundation base, and the geometric profile of the cross section of the build-in structure is the same as the shape of the cross section of the cylinder delineator, and the size of the build-in structure, in any directions, is wider than the column-type delineator; and cylindrical grooves are formed in the inner wall ofthe build-in structure at set intervals in the depth direction and at set intervals in the circumferential direction, and the cylindrical grooves are used for clamping and fixing elastic convex pinson the under buried part of the column-type delineator. The invention further discloses a construction method of the improved column-type delineator under the narrow road shoulder conditions. Productsof the improved column-type delineator have higher production and construction efficiency, lower maintenance cost, and are effectively applied to narrow road shoulders or special road sections whichare near water or near cliffs.
Description
technical field [0001] The invention belongs to the technical field of traffic safety facilities, and in particular relates to an improved column delineator and a construction method thereof under narrow road shoulder conditions. Background technique [0002] Column delineation markers are traffic safety facilities with retroreflective properties set along the edges of both sides of the road to indicate the direction of the road. In recent years, materials such as synthetic resins (such as PVC plastic) have been widely used to make column delineators. These materials have high strength and high elasticity and high impact resistance, and can usually protect both vehicles and delineators from damage. [0003] Low-grade (rural and mountainous) roads usually have narrow road surfaces and small shoulder widths. Especially in special areas such as mountainous roads near water (cliffs), due to the extremely limited roadside space, there are great difficulties in the installation an...
