Description

Technical Field

[0001] This utility model relates to the field of pedestrian walkway technology, and in particular to a pipe pile foundation pedestrian walkway. Background Technology

[0002] Waterfront walkways are typically located on riverbanks, lakeshores, or mudflats. Traditionally, these walkways often used bored piles or concrete piers as foundations, with cast-in-place concrete beams supporting the walkways, topped with wooden planks or precast concrete slabs. During project implementation, several drawbacks were discovered. For example, the guardrail posts were directly installed onto the wooden planks or precast concrete slabs on the beams. If wooden planks were used, the posts were screwed into the planks, causing the posts to wobble and resulting in poor stability. If precast concrete slabs were used, the expansion bolts were installed onto the slabs, but since the posts were located at the edges of the slabs, there was a risk of cracking at the edges, further contributing to insecure installation.

[0003] In addition, the existing construction method uses cast-in-place concrete for the support beams, which presents problems such as high construction difficulty and complex procedures, resulting in low construction efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a pipe pile foundation pedestrian walkway, including pipe piles arranged in two rows at intervals. Each row of pipe piles has a capping beam installed on its top, and walkway slabs are installed on the top of the capping beams on both sides. Guardrails are installed on one or both sides of the walkway slabs in the width direction. Blind holes are reserved at intervals along the length direction on the top of the capping beams. The walkway slabs have slots corresponding to the blind holes. The guardrail posts are inserted into the slots and blind holes and then fixed by a connecting layer.

[0006] The capping beam is installed in segments on top of the pipe pile.

[0007] The two ends of the crown beam are respectively erected on the top of the adjacent pipe piles. The two crown beams on the top of the pipe piles are connected by a post-cast section. The bottom of the post-cast section is fixedly provided with a first connector, which is inserted into the central hole at the top of the pipe pile.

[0008] A stop block is installed in the central hole at the top of the pipe pile, and the first connector is located on the upper side of the stop block. Concrete is poured into the central hole on the upper side of the stop block.

[0009] The top of the two rows of pipe piles is also equipped with a connecting beam, with both ends of the connecting beam erected on top of the pipe piles and connected to the post-cast section.

[0010] The top of the crown beam is provided with a leveling layer.

[0011] The top of the crown beam and the tie beam is provided with a leveling layer.

[0012] The lower side of the walkway plate is fixedly provided with a plurality of second connecting pieces, which are located outside the crown beam and connected with the crown beam through fasteners.
