Problems solved by technology

Moreover, the location where cracks occur is a weak load area, and uncontrollable cracks will gradually widen or break under heavy traffic, affecting aesthetics and traffic
[0003] A common way to solve the above problems in the field of construction is to set saw marks on the road surface. This saw mark is generally set when the concrete is solidified enough for workers to operate. However, the width of the saw marks is wide. In order to make the road surface If it is relatively smooth, it is necessary to fill appropriate elastic materials into the saw marks, which increases the construction cost; crack inducers are arranged at appropriate positions on the road surface, but the crack inducers in the prior art are quadrilateral, circular or triangular in cross section The concrete cracks formed by the pillars are relatively large, generally 3-10mm, and not uniform, which will affect the aesthetics of the road surface and the comfort of driving

Abstract

The active induced cracking device comprises a foundation trench formed in the top face of a soil layer, a base layer is arranged on the bottom face of the foundation trench, a bonding layer is arranged on the top face of the base layer, a graphene concrete layer is arranged on the top face of the bonding layer, and the graphene concrete layer is arranged on the top face of the graphene concrete layer. A plurality of main reinforcements are laid on the top in the graphene concrete layer in the transverse direction of the pavement at equal intervals, a plurality of erection reinforcements are laid below the main reinforcements in the longitudinal direction of the pavement at equal intervals, and the crossed positions of the erection reinforcements and the main reinforcements are bound through steel wires; a plurality of induction parts are laid at equal intervals below the plurality of erection ribs in the longitudinal direction of the road surface, a plurality of heat conduction parts are welded at equal intervals on the bottom surfaces of the induction parts, the bottoms of the heat conduction parts penetrate through the bonding layer and then are located in the base layer, and the tops of the heat conduction parts are located in the graphene concrete layer.

Description

Technical field [0001] The present invention relates to the field of concrete crack induction, in particular to a kind of active induction cracking device suitable for continuous reinforcement of concrete pavement. Background [0002] When concrete builds roads, shrinkage occurs during drying and cracking occurs if concrete does not fully adapt to shrinkage strain. In the absence of other special treatments, cracks usually appear on the pavement in the first three months after the concrete road is paved, and these cracks are usually snaked at any angle on the concrete pavement, and the shape and irregularity of the road surface affect the overall appearance of the pavement. Moreover, the location of the crack is a load weak area, and the uncontrollable crack will gradually widen or break under heavy traffic, affecting the aesthetics and traffic. [0003] Common ways to solve the above problems in the construction field are: to set a saw mark on the road surface, this saw mark is ...
