Asphalt pavement construction pay-off pile and pay-off construction method

Abstract

The invention provides an asphalt pavement construction pay-off pile and a pay-off construction method. The asphalt pavement construction pay-off pile comprises a pile head and a pile leg connected tothe lower end of the pile head; a supporting rod is rotatably connected to one side of the pile head, and a guide bearing is rotatably connected to the end, away from the pile head, of the supportingrod; the guide bearing and the pile head are connected through a steel wire rope and a euphroe; the tail end of the steel wire rope is connected with one end of the euphroe after bypassing the guidebearing, and a connecting wire at one end, far away from the guide bearing, of the euphroe is connected with the pile head; moreover, the lower side of the supporting rod is connected with an adjustable inclined strut, and the adjustable inclined strut is used for adjusting the height of the guide bearing on the supporting rod. According to the invention, the problems that the final flatness of the asphalt pavement is poor or even unqualified or the thickness of a pavement structure layer is wrong due to the fact that a datum line is stressed unevenly in the tensioning process or deflection ofthe datum line is casused since the steel wire rope is loosened when the steel pile slides up and down can be solved.

Description

technical field [0001] The invention relates to the technical field of construction tool design, and more specifically, to a setting-out pile for asphalt pavement construction and a setting-out construction method. Background technique [0002] The paving of asphalt pavement on modern highways and urban roads is carried out by modern large-scale paver. Whether it is the water-stabilized base of the road or the middle and lower layers of the asphalt pavement, the paver is used to hang the base from left to right. The two sensor tentacles on the left and right slide forward on the thin steel wire ropes on the left and right sides, commonly known as the "tight wire walking" method. Usually, a steel wire rope with a diameter of 2-3mm is used as the reference line. The two ends of the steel wire rope are connected to the steel piles. And the dynamometer, the tensioning length is preferably 150-200m, and the two ends must be tensioned at the same time with a rope tensioner to avoi...

AI Technical Summary

Problems solved by technology

[0005] In view of the above problems, the purpose of the present invention is to provide a kind of asphalt pavement construction setting-out stake and construction method, to solve the uneven tensile force of the reference line or make the steel wire rope slack when the steel pile slides up and down, so that the reference line produces deflection, thereby The final flatness of the pavement is not good, or even unqualified, or the thickness of the pavement structure is wrong.
