Embodiment approach

[0037] As an embodiment of the present invention, the protrusion of the flower-shaped cam 8 is provided with an arc-shaped shrapnel 81; the arc-shaped shrapnel 81 is made of high-temperature-resistant rubber; When pressing the arc-shaped shrapnel 81, the arc-shaped shrapnel 81 is depressed after being squeezed, and then fits with the round end surface of the perforated steel needle 9, so that the round end surface of the perforated steel needle 9 will not Sliding relative to the surface of the flower-shaped cam 8, the impact force can be transmitted to the transmission shaft 7, preventing the perforating steel needle 9 from bending due to the inclined force, thereby improving the service life of the perforating steel needle 9.

[0038] As an embodiment of the present invention, a No. 1 through hole 811 is set in the middle of the arc-shaped shrapnel 81; a No. 1 cavity 82 is set on the protrusion of the flower-shaped cam 8; when in use, the round head of the punching steel needl...

Abstract

The invention belongs to the technical field of road maintenance, Specifically, the invention relates to an expressway pavement repairing method, the pavement restoration device in the method comprises a housing, an electric motor, a gear shaft, a driven gear, a rolling drum, a fixed shaft, a clutch, a transmission shaft, a pattern cam, and a perforated steel needle, wherein one end of the rollingdrum is rotatably installed on a side wall of the housing through the fixed shaft, a bevel gear is arranged on the other end face of the rolling drum, and the upper part of the bevel gear at the endof the rolling drum is meshed with the bevel gear at the lower end of the gear shaft to realize transmission; because the clutch is arranged at one end of the transmission shaft, and a group of pattern cams is uniformly arranged on the transmission shaft, The perforated steel heated on the rolling drum is used to punch holes on the damaged pavement, and the pavement is heated at the same time, andthe shrinkage can be realized; furthermore, the softened pavement is rolled by the rolling drum, the pavement is leveled, the pavement is repaired quickly, and the smoothness of the expressway is ensured.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, in particular to a method for repairing highway road surfaces. Background technique [0002] In high-grade highways, asphalt pavement is valued by countries all over the world for its well-known good performance. , no dust, small vibration, low noise, short construction period and easy maintenance and repair, etc., are widely used in expressways. With the development of highways in my country and the increase of traffic volume, rutting is the main form of damage to asphalt pavement. Rutting is the accumulation of permanent deformation in the vertical direction of the wheel track belt on the roadway under repeated wheel loads. When it is serious, there are usually bulging deformations on both sides. It is mainly caused by viscous flow of asphalt mixture, deformation of soil foundation and base course, and includes a certain degree of compaction and material wear. [0003] At present, t...
