Top-down construction type assembly construction method for paved road surface

A top-down construction type assembly construction method for paved road surface, wherein, comprising the following steps I-II:

• in the step I, manufacturing prefabricating slabs:
• using a top-down method to manufacture the prefabricating slabs, and providing bolt sleeves that are configured to vertically penetrate, inside the prefabricating slabs, which are evenly arranged in the prefabricating slabs;
• and
• in the step II, mounting the prefabricating slabs:
• on a lower bearing plate which is clean, placing the prefabricating slabs in one step according to a mounting sequence of a mounting section, then performing a fine tuning on a position and an altitude of the prefabricating slabs, and after the fine tuning is completed, performing a grouting construction, and finally forming the paved road surface which is complete;
• wherein a step of the fine tuning for the position and the altitude of the prefabricating slabs comprises:
• an altitude coarse tuning, a position fine tuning, and an altitude fine tuning;
• and
• in the altitude coarse tuning, screwing a leveling bolt, where a lower end of the leveling bolt is contacted with a concrete surface of the lower bearing plate, into the bolt sleeves of each of the prefabricating slabs, and lifting the prefabricating slabs by screwing the leveling bolt until a slab surface altitude of the prefabricating slabs is in accordance with a hanging line altitude of the prefabricating slabs;
• and
• in the position fine tuning, lifting the prefabricating slabs a certain distance through a lifting equipment, manually pushing the prefabricating slabs to a desired distance, and slowly lowering the prefabricating slabs;
• and
• in the altitude fine tuning, measuring altitudes at four corner points of the prefabricating slabs one by one through an electronic level, after measuring all points and calculating adjustment values, planing an adjustment sequence uniformly through an adjustment principle which is a balancing adjustment, and screwing the leveling bolt according to a planing sequence;
• and
• in the step I, manufacturing the prefabricating slabs on a super flat prefabricating pedestal, firstly mounting and fixing a side mold, and reversely buckling a brick on the super flat prefabricating pedestal inside the side mold, arranging the brick on the super flat prefabricating pedestal which has already laid a demolding barrier layer, and filling a brick joint through a caulking strip;
• mounting a first reserving hole mold after completing a reverse laying of the brick, then laying one layer with 8 mm˜10 mm thick of a polymer dry mix mortar on a back of the brick, and after a final set of the polymer dry mix mortar, mounting a first reinforcing mesh sheet, a second reserving hole mold, a second reinforcing mesh sheet and a pre-embedding steel slab, fixing the bolt sleeves on the pre-embedding steel slab, and opening a grouting hole on the pre-embedding steel slab;
• after completing above steps, pouring a concrete to finally form one complete piece of the prefabricating slabs;
• after a concrete strength is reached 75% of a design strength, cooperating with a crane to flip the side mold at a sand pile, checking an evenness and a specification dimension of a brick surface of the prefabricating slabs, and promptly digging out the caulking strip for the prefabricating slabs which is qualified and pointing a joint, and then numbering and storing the prefabricating slabs;
• and
• wherein the second reserving hole mold and the first reserving hole mold are mounted at a position corresponding to the bolt sleeves, when pouring the concrete inside the side mold, and insides of the second reserving hole mold and the first reserving hole mold are not poured, and the position corresponding to the first reserving hole mold is not paved with the brick as a leveling and grouting reserving hole.
