[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0022] like Figure 1 , Figure 2As shown, an aqueduct sidewalk slab structure provided in this embodiment includes an aqueduct 2 and a sidewalk slab installed on the aqueduct 2, and the sidewalk slab includes a slab body 1, a guardrail 3 and anchor bars 4.

[0023] like Figure 1 As shown, the upper surface of the plate body 1 is provided with a second boss 12, and the second boss 12 extends along the length direction X. The lower surface of the plate body 1 is provided with a first boss 11. The width W1 of the first boss 11 is less than the width W2 of the second boss 12. The first boss 11 with a small width can interlock with the notch 21 on the aqueduct 2, and the second boss 12 with a large width is conducive to installing the guardrail 3. The upper surface of the plate body 1 between the two second bosses 12 forms a pedestrian passage surface, such as Figure 2 As shown, expansion joints 5 and drainage cover plates 6 are provided at the joints of two adjacent plate bodies 1. The drainage cover plates 6 are located in the middle of the plate body 1 (i.e., on the surface of the pedestrian passage), and the expansion joints 5 are located at both ends of the drainage cover plates 6 (i.e., at the second bosses 12). The drainage cover plates 6 are provided with a plurality of drainage slots.

[0024] like Figure 1 As shown, the aqueduct 2 includes a trough body 22 and a plurality of connecting beams 23 connected to the upper end of the trough body 22, and the plurality of connecting beams 23 are arranged at intervals along the length direction X. The trough body 22 is a U-shaped trough, and its inner bottom surface is semicircular. The connecting beams 23 are cylindrical. The notch 21 is an L-shaped groove, which horizontally passes through the trough body 22. The first boss 11 is placed in the notch 21, and the inner side wall of the notch 21 interacts with the first boss 11 to prevent the plate body 1 from horizontal displacement.

[0025] The guardrail 3 includes a plurality of vertical poles and a crossbar or a steel wire rope or a chain connected between the plurality of vertical poles. Figure 1 , Figure 2 The plate body 1 is provided with a plurality of plates along the length direction X of the aqueduct 2. The vertical poles are installed on the second boss 12 through anchor bars 4, and the plurality of vertical poles are evenly distributed along the length direction X. A portion of the anchor bars 4 is located in the plate body 1, and another portion is located in the vertical poles of the guardrail 3. The body 1 and the guardrail 3 enclose a pedestrian passage.

[0026] The plate body 1 is a prefabricated plate, which is processed in the factory. The anchor bar 4 is pre-buried on the plate body 1, and the first boss 11 is pre-buried with a PVC exhaust pipe to form an exhaust hole 13. Before installing the guardrail 3, a corresponding plug hole is set in the vertical pole to be inserted with the anchor bar 4. Before installing the plate body 1, cement mortar is applied in the notch 21. The exhaust hole 13 is through along the width direction Y of the plate body 1, and a plurality of exhaust holes 13 are arranged at intervals along the length direction X of the plate body 1. The exhaust hole 13 connects the upper space of the aqueduct 2 with the outside world, and can discharge the internal gas of the aqueduct 2 to a certain extent.

[0027] The expansion joint 5 is provided with a closed-cell foam board, which can adapt to the thermal expansion and contraction of the board body 1. The drainage cover plate 6 is a cast iron cover plate or a stainless steel cover plate, which allows the rainwater on the board body 1 to be drained smoothly and avoids water accumulation.

[0028] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
