The present invention is featured as follows: said pillar 2 and said bearing beam 3 are both precast concrete structural pieces; the pillars 2 at the left and right sides of the road surface respectively are connected with each other through the bearing beam 3 at the tops thereof, so as to form a one-piece precast supporting frame unit 10 with a shape similar to “[]” as shown in Fig. 2; and a plurality of supporting frame units 10 are arranged along the extending direction of the road surface. Said base 1 is of a cast-in-situ concrete structure, and is securely cast with the bottoms of said pillars 2 at the construction site. The supporting frame unit 10 together with the base 1 forms a bearing main body structure. Said cover 5 is a semi-precast structure, mainly comprising a precast base slab unit 51 and a cast-in-situ concrete top layer 52 that is incorporated with the precast base slab unit 51.
As shown in Fig. 3, two precast base slab units 51 are mounted between two adjacent supporting frame units 10. As shown in Fig. 4, an enclosure plate 54 extending upwardly and a supporting frame connecting plate 55 extending downwardly are provided at the left and right sides of the cast-in-situ base slab unit 51, wherein said supporting frame connecting plate 55 retracts inwardly at the end thereof connecting with the supporting frame unit 10, thus forming a gap 56 that precisely matches with the connecting end of the supporting frame unit 10 in a manner of form-fitting. The end of said precast base slab unit 51 with the gap 56 rests against the bearing beam 3 of the supporting frame unit 10, and the other end thereof is attached to another precast base slab unit 51. When the walkway is formed into a straight line, said precast base slab unit 51 is of a square shape. When the walkway is formed into a curve line, said precast base slab unit 51 is formed by assembling several fan-shaped structures, in order to be in line with the curvature of the walkway.
As shown in Fig. 1, said cast-in-situ concrete top layer 52 is cast on the top of the precast base slab unit 51, so that it connects all precast base slab units 51 together.
Moreover, at each of the left and right sides, in a position corresponding to the pillar 2, an upstanding beam 53 in parallel with the centerline of the walkway is cast, in order to guarantee the firmness of the whole cover 5. Said upstanding beam 53 is cast on the inner side surface of the enclosure plate 54, and the area between the left and right upstanding beams 53 may form a large greening area.
