Referring to fig. 2, a novel fabricated water plank road structure is shown, which comprises a plurality of prefabricated plank road units 100 arranged side by side along the extension direction of the plank road. Each prefabricated plank road unit 100 comprises four prefabricated pile foundations 110 and prefabricated beamless slabs 120. Of course, the number of the precast pile foundations 110 is not limited to the number in the embodiment, and it should be set according to actual support requirements, and it should be set to be at least three so as to provide stable support.
Four prefabricated pile foundations 110 are arranged at intervals on the river bank, each prefabricated pile foundation 110 is preferably a prefabricated square pile, and a circle of lower steel plates 111 are embedded on the outer circumferential surface of the pile top of each prefabricated pile foundation 110 except the pile top surface, as shown in fig. 3 and 4. The pre-buried lower steel plate 111 is mainly used for connecting the prefabricated pile foundation 110 and the prefabricated beamless plate 120, and meanwhile, the pile top is a part which is easy to damage during pile driving, and the lower steel plate 111 has a fastening effect, so that the damage of the pile head can be avoided.
Referring to fig. 5 to 8 in combination with fig. 15 and 16, the prefabricated beamless slab 120 is placed on the tops of four prefabricated pile foundations 110, and upper steel plates 121 are embedded in the lower slab surface of the prefabricated beamless slab 120 at positions contacting the pile tops of each prefabricated pile foundation 110. During assembly, the lower steel plate 111 of each prefabricated pile foundation 110 is welded and fixed with the upper steel plate 121 corresponding to the prefabricated beamless plate 120, so that the prefabricated beamless plate 120 and the prefabricated pile foundation 110 are combined to form a whole. The prefabricated beamless plate 120 is prefabricated and formed at one time in a prefabrication factory, and four upper steel plates 121 are embedded on the lower plate surface of the prefabricated beamless plate 120 during prefabrication.
The precast beam-free plate 120 is provided with a tenon 122 along one side of the extension direction of the plank road, and a tenon 123 along the other side of the extension direction of the plank road; when two adjacent precast girderless slabs 120 are assembled, the tenon 123 of one precast girderless slab 120 is inserted into the mortise 122 of the other precast girderless slab 120.
