Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] A specific embodiment of the prefabricated pavement construction method of the present invention comprises the following steps:
[0031] S1, such as Figure 7 As shown in the figure, the composite bearing prefabricated road slab 3 is processed, a steel frame 32 is placed in the mold, a plurality of pre-embedded hook bolts 33 are uniformly welded on the steel frame 32, and a conical surface coated with a release agent is arranged at intervals in the mold...

The invention provides a composite bearing prefabricated pavement slab and a prefabricated pavement construction method. The composite bearing prefabricated pavement slab is machined; an original soillayer is ground and punned; a leveling layer is paved on the original soil layer and is punned; the formed composite bearing prefabricated pavement slab is hoisted to the construction road segment and is mounted in place, the composite bearing prefabricated pavement slab is subjected to primary static pressing to be attached to the leveling layer, and caulking is carried out between two adjacentparts of the composite bearing prefabricated pavement slab through waterproof mortar; a small drill machine drills various conic pile head holes in the composite bearing prefabricated pavement slab from top to bottom, and brace pile pouring holes are formed after soil clearing; and concrete is poured downwards from the upper portions of the conic pile head holes till inner cavities of the brace pile pouring holes and the conic pile head holes are full of concrete, and brace piles are formed. The overall bearing capacity of the pavement slab is improved, and the bad influence of a settlement roadbed on the pavement is reduced; and the overall connectivity of the prefabricated pavement and the base layer is enhanced, lateral horizontal sliding of the prefabricated pavement is reduced, and the overall stability of the roadbed and the pavement is improved.
Description
technical field [0001] The invention relates to a composite bearing prefabricated road slab and a construction method for the prefabricated road surface. Background technique [0002] Prefabricated pavement refers to the pavement made of cement concrete prefabricated blocks. There are two main problems in the use of prefabricated roads. Due to the prefabricated pavement itself being assembled and formed, the overall combination with the roadbed is not good, the sealing is not strict, and the quality of the roadbed is high. In the later stage, with problems such as rainwater penetration and uneven settlement of the roadbed, it is very easy to cause warping and unevenness. Lead to problems such as cracking and breaking of prefabricated pavement. It cannot meet the long-term load stability requirements of the road. As a result, it is difficult to popularize prefabricated roads. Contents of the invention [0003] The purpose of the present invention is to provide a composit...
