The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In the description of the present invention, the terms "upper" and "lower" refer to the relative positional relationship when the crack inducer 1 is used, that is, the relative positional relationship after the crack inducer 1 is laid on the upper surface of the roadbed.
In the basic embodiment of the present invention, as shown in fig. 1 and 2, the present invention provides a crack inducer 1, wherein the crack inducer 1 has a cylindrical shape, and the crack inducer 1 has an upper inducer bottom surface 11 and a lower inducer bottom surface 12, the upper inducer bottom surface 11 is an arc surface protruding outward, and the lower inducer bottom surface 12 is a flat surface or an arc surface recessed toward the upper inducer bottom surface 11.
Specifically, the crack inducer 1 may be provided in a solid columnar shape or a hollow columnar shape. The material of the crack-inducing member 1 may be a polymer material used for preparing the crack-inducing member 1 in the prior art, or other materials. The polymer material used for the crack inducer 1 may be polyethylene, polytetrafluoroethylene or other common polymer materials.
When the crack guiding piece 1 provided by the basic implementation works, a roadbed is moved to be flat, reinforcing steel bars are arranged above the roadbed at intervals, the extending direction of the reinforcing steel bars is consistent with the extending direction of a road surface, the crack guiding piece 1 is placed on the reinforcing steel bars, the lower bottom surface 12 of the crack guiding piece is in contact with the reinforcing steel bars, then concrete is poured, and the distance from the surface of the concrete road surface to the highest point of the crack guiding piece 1 is 5-20 mm.
In the crack guiding member 1 provided by the above basic embodiment, the upper bottom surface 11 of the guiding member is set to be an arc-shaped surface protruding outwards, and the lower bottom surface 12 of the guiding member is set to be a plane or an arc-shaped surface protruding towards the upper bottom surface 11 of the guiding member, so that a concrete pavement can generate better stress release in the use process, and therefore, cracks with smaller width and more uniform width are generated on the concrete pavement, and the aesthetic degree of the pavement is ensured. In the using process, the width of the crack gap generated by the crack inducer 1 provided by the invention is less than 0.5 mm. And the gap is just arranged above the crack inducing piece 1, so that the strength of the crack of the concrete pavement can be ensured, the service life of the concrete pavement is prolonged, meanwhile, the water infiltration can be reduced, and the influence of the water infiltration on the overall structure of the pavement is reduced. The possibility of bumping in the driving process can be reduced, and the driving comfort is improved.
In one embodiment of the invention, the arc height h of the upper bottom surface 11 of the leader is 40-60mm, and the ratio of the arc height h of the upper bottom surface 11 of the leader to the chord length L of the upper bottom surface 11 of the leader is 1: 1.5-4. The crack inducer 1 can enable the concrete pavement to generate better stress release in the using process of the crack inducer, so that cracks with smaller width and more uniform width are generated on the concrete pavement.
Specifically, as shown in fig. 3 and 4, the chord length is the distance between two side edges of the upper bottom surface 11 of the inducer, and the arc height h is the distance between the chord length and the highest point of the upper bottom surface 11 of the inducer.

Better stress relief of the concrete slab during use of the crack inducer 1 is achieved, resulting in a smaller and more uniform width crack in the concrete slab.
In one embodiment of the invention, the crack-inducer 1 is a glass fibre reinforced polymer moulding.

The crack-guiding member 1 made of the glass fiber reinforced polymer is easier to separate from the concrete, and the crack-guiding member 1 made of the material can generate better stress relief on the concrete pavement to obtain cracks with smaller width.
In one embodiment of the invention, as shown in fig. 3 and 4, an inducer cavity 13 is provided between the inducer upper base surface 11 and the inducer lower base surface 12.

In one embodiment of the invention, the radius of curvature of the curved bumper tab 14 is less than the radius of curvature of the upper bottom surface 11 of the inducer. By enabling the curvature radius of the arc-shaped buffer sheet 14 to be smaller than that of the upper bottom surface 11 of the guiding piece, better stress release can be generated by pressing the arc-shaped buffer sheet 14 in the use process of the crack guiding piece 1, so that the concrete pavement also has better stress release, and cracks with smaller width and more uniformity are generated on the concrete pavement.
