Description

Technical Field:

[0001] The utility model belongs to the technical field of the design of road construction auxiliary tools, and relates to a fixing device for asphalt pavement setting-out and fixing Background Art:

[0002] In the current asphalt pavement construction technology, large asphalt paving equipment is mostly used for paving, and the wire-walking method is a widely used elevation control method in asphalt pavement paving construction. The operation process is as follows: first, steel pins are nailed on both sides of the route at the designed interval (the interval is generally 5-10 meters, not exceeding 10 meters in the straight section, and not exceeding 5 meters in the curve section. The steel pins should be set 30-40 centimeters outside the paving width), and a steel wire serving as a reference wire is hung on the steel pins. The diameter of the selected steel wire is usually 2-3 millimeters, and both ends need to be connected with a wire tightener and a dynamometer to ensure uniform tension of the steel wire and avoid deflection. The sensor of the paver slides along the steel wire, and the surveyors monitor in real time and adjust the paving thickness and elevation in real time.

[0003] Although the wire-walking method is easy to construct and has low cost, there are also many problems. This method has problems such as cumbersome binding, insecure fixation and being easily interfered by the outside world (such as wind force, etc.) resulting in wire off, poor positioning accuracy, and trouble in later horizontal or elevation adjustment, which affect the paving accuracy and progress; at the same time, the steel wire may be fatigued under the tension state, resulting in uneven deflection of the road surface and affecting the flatness; in addition, it has a high dependence on manual operation, the positioning quality is difficult to control, and special personnel are required to watch and frequent measurement and correction are needed, which increases the construction cost and time.

[0004] These factors limit the application of the wire-walking method in some complex construction environments. In order to facilitate construction, eliminate disadvantages and improve efficiency, it is necessary to improve and adjust the existing asphalt pavement setting-out and fixing device so that the new construction method is more suitable for on-site construction.
