Technical Field

The utility model belongs to the field of highway ecological safety, and particularly relates to a grazing passage.

Background

With the development of socioeconomic, the demand of transportation is vigorous, and the construction of roads is continuously expanded to pastoral areas such as grassland and abdominal land. At present, roads constructed on grasslands mainly adopt the position where herdsmen have cattle and sheep to cross the road, and are specially provided with cattle and sheep sign notice boards to prompt drivers to slow down and pay attention to avoiding cattle and sheep. Due to the disorder of the cattle and sheep crossing the road, traffic accidents at over-herd positions still frequently occur, and the over-herd safety problem has led to high attention of all relevant departments. The area of a grassland is large, the grazing safety appeal of herdsmen is strong, and the highway construction needs to adopt a more effective mode to ensure the grazing safety of the herdsmen.

SUMMERY OF THE UTILITY MODEL

The grazing passage provided by the utility model has the characteristics of safety, reliability, flexible arrangement, simple structure and the like.

In order to solve the technical problems, the utility model provides a grazing passage, which is characterized in that: including a plurality of pin structures, every pin structure includes top crossbeam and the stand of lower part, the top both sides of top crossbeam are equipped with the road bed dog, and the bottom sets up a plurality of splice segments along perpendicular highway line direction, splice segment and stand fixed connection.

Has the advantages that: the oversleeping channel structure takes one truss as a unit, can be flexibly arranged by two or more trusses according to the local oversleeping quantity of cattle and sheep, and is flexible to arrange. By adopting the prefabrication and installation method, the damage to the grassland environment is small, and the construction is rapid. The beam body is hoisted in a mode that hoisting holes are formed in the top cross beam, so that sling embedded parts are saved, and the construction cost is reduced.

Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention is provided.

The utility model provides a grazing passage which is characterized by comprising a plurality of one-truss structures, wherein each one-truss structure comprises a top cross beam 1 and an upright post 2 at the lower part, both sides of the top cross beam are provided with roadbed stop blocks 4, the bottoms of the top cross beams are uniformly provided with a plurality of joint sections of solid cylinders, and the joint sections are connected with the upright posts; the joint section is of a solid cylindrical concrete structure.

The cross section of the top cross beam and the cross section of the joint section form a T-shaped structure, the top width is 3300-4300mm along the road line direction, the bottom width is 800mm, the height of the T-shaped root part, namely the height of the joint section, is 700mm, the height of the T-shaped end part is 350mm, and the middle height is in linear transition.

Wherein, the perpendicular highway line direction both ends of top beam set up the road bed dog respectively, and the road bed dog is trapezium structure, and height 300mm, the wide 200mm in top, the wide 350mm in end, the inclination is 1: 0.5;

the lower part of the top cross beam is provided with a plurality of joint sections along the direction vertical to a highway line, the center distance is 3.5-5.0 m, and the diameter is 800 mm.

And the PHC tubular pile extension embedded parts are embedded at the end parts of RC joint sections at the lower part of the top cross beam.

The PHC pipe pile is arranged below the joint section, the section of the PHC pipe pile is a circular section, the diameter of the PHC pipe pile is 800mm, the wall thickness of the PHC pipe pile is 110mm, the PHC pipe pile is arranged along the direction vertical to a highway line, the center distance is 3.5-5.0 m, and the PHC pipe pile is aligned with the joint section;

the length of the upright post entering the ground is determined according to geological conditions, and the length of the ground is not less than the height above the ground.

And the RC joint section at the lower part of the top cross beam and the stand column are welded into a whole through a PHC tubular pile extension embedded part.

And after the welding is finished, spraying a similar concrete color antirust paint on the pile splicing part.

The over-grazing channel structure can be arranged in two or more frames along the road line direction according to the local over-grazing demand;

wherein the clearance of each over-herding channel structure along the road line direction is 20 mm;

asphalt reinforcement 7 is filled in gaps of the overswing channel structure of each truss;

the grazing passage is manufactured by the following method:

installing an external template on the pedestal, and transferring the PHC pipe pile extension embedded part and the bound reinforcement cage into a mold;
