Embodiment 1
[0046] figure 2 A schematic diagram of a partially longitudinally cut side view structure of the slip-type continuously reinforced concrete pavement provided by Embodiment 1 of the present invention, as shown in figure 2 As shown, the sliding type continuously reinforced concrete pavement comprises: a base layer 1, on which a sliding type continuously reinforced concrete pavement surface layer 2 formed by pouring concrete 21 is laid; There are continuous reinforcing bars 22 and erecting reinforcing bars 23, the continuous reinforcing bars 22 are bound on the erecting reinforcing bars 23, expansion joints 4 are arranged on both sides of the continuous reinforcing bars 22; wherein, during the construction process, erecting The vertical steel bar 23 can be erected directly on the base layer 1, instead of adopting the method of drilling and anchoring the erection. The expansion joints 4 on both sides of the continuous steel mesh 22 are at the longitudinal ends of the slip-type ...
Embodiment 2
[0050] image 3 It is a partial top view structural diagram of the sliding continuous reinforced concrete pavement provided by Embodiment 2 of the present invention. On the basis of Embodiment 1, the continuous reinforcement mesh 22 can be a single-layer reinforcement mesh or a double-layer reinforcement mesh. like image 3As shown, the continuous steel mesh 22 may comprise longitudinal bars 221 and transverse bars 222 which may be arranged at a set angle relative to the longitudinal bars 221 . In the pavement structure, the driving direction is the longitudinal direction, and the pavement width direction is the transverse direction.
[0051] Although the sliding continuous reinforced concrete pavement is easy to crack under the vertical load of the vehicle and the warping deformation of the long slab, the crack is a closed movable crack under the constraint of the continuous steel mesh, and the crack width can be effectively controlled. The crack width is less than or equal...

[0057] Figure 4 Schematic flow chart of the construction method of the sliding continuously reinforced concrete pavement provided in Embodiment 3 of the present invention, wherein the sliding continuously reinforced concrete pavement is any one of the structures provided in the above-mentioned Embodiment 1 and Embodiment 2 slippery continuously reinforced concrete pavement, such as Figure 4 As shown, the construction method of the sliding type continuous reinforced concrete pavement comprises the following steps:
[0058] Step 101, laying a drag-reducing layer on the base;
[0059] Step 102, setting erection steel bars on the drag reducing layer;
[0060] Step 103, binding the continuous reinforcement mesh on the erection reinforcement;
[0061] Step 104, pouring concrete on the drag-reducing layer forming the erection steel bars and the continuous steel mesh, and setting expansion joints on both sides of the continuous steel mesh to form the sliding continuous reinforced...
