In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
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. Uneven settlement between two precast beamless panels 120 may be reduced by the rebates. Further, the precast beamless slab 120 is formed with a first local thickened part 124 protruding downward along one side of the extension direction of the plank, and is formed with a second local thickened part 125 protruding downward along the other side of the extension direction of the plank, the tenon 122 is arranged on the first local thickened part 124, the tenon 123 is arranged on the second local thickened part 125, and the shearing resistance is enhanced by performing local thickening treatment at the joint of the two precast beamless slabs 120. In order to facilitate the positioning of the installation on site, the tenon 122 and the tenon 123 adopt a semicircular structure.
Referring to fig. 11 and 12 in combination with fig. 14, at least one leveling steel plate 130 for leveling is padded between the lower steel plate 111 on each prefabricated pile foundation 110 and the corresponding upper steel plate 121 of the prefabricated beamless slab 120. The leveling steel plate 130 mainly plays a leveling role, and since the field piling is limited by the construction process, the pile top elevation cannot be ensured to be at the same elevation after the piling is finished, and the height is inevitably uneven, at this time, the leveling steel plate 130 is used for leveling the erected precast pile foundation 110, and then the precast beamless slab 120 is hoisted. The plane size of the leveling steel plate 130 is consistent with the size of the pile top surface of the precast pile foundation 110. The leveling steel plates 130 are divided into two types, one is a thick steel plate for rough leveling having a thickness of 10mm, and the other is a thin steel plate for precise leveling having a thickness of 1 mm.
A pavement layer 200 is laid on the surface of the precast beamless slabs 120 of the several precast plank road units 100 arranged side by side. Railings 300 are respectively arranged on the two sides of the pavement layer 200 on the prefabricated beamless plates 120 of the plurality of prefabricated plank road units 100 arranged side by side.
The invention discloses a construction method of a novel assembly type water plank road structure, which comprises the following steps:
step S10, laying four prefabricated pile foundations 110 in each prefabricated plank road unit 100 at intervals on the river bank, as shown in fig. 10;
