Abstract
The invention discloses a structure for preventing a laying surface layer from cracking and a method for preventing the laying surface layer from cracking. The laying surface layer is laid on a concrete pad layer; the concrete pad layer is provided with a plurality of expansion joints; an isolation layer used for buffering the relative deformation between the concrete pad layer and the laying surface layer is arranged in a position, corresponding to each expansion joint, between the concrete pad layer and the laying surface layer; the longitudinal direction of each isolation layer extends in the longitudinal direction of the corresponding expansion joint; and each isolation layer covers the corresponding expansion joint. When the concrete pad layer generates vertical deformation under the load effect or generates horizontal deformation when the temperature changes, the isolation layers can achieve the buffer effect between the concrete pad layer and the paving surface layer; and a tension fracturing phenomenon of the laying surface layer due to vertical or horizontal deformation of the concrete pad layer is prevented. In addition, a square sliding steel sheet can bear great shearing force when the vertical staggering of the concrete pad layer occurs; the excessive vertical deformation is avoided; the multi-direction sliding quantity can be provided in the horizontal direction; and the surface layer laying cracking can be controlled to the maximum degree.
