Description

Technical Field

[0001] The utility model relates to the technical field of prestressed high-strength concrete piles, in particular to a prestressed high-strength concrete pile without end plate connection. Background Art

[0002] Prestressed high-strength concrete piles are a kind of tubular slender components driven into the soil, with a cross-sectional size much smaller than its length. The upper part of the pile is connected to the pedestal (beam) to form a pile foundation.

[0003] For example, a prestressed high-strength concrete pile without end plate connection has the authorization announcement number "CN220486419U", in which multiple groups of connecting blocks are inserted into the circumferential side of the pile body segment, and the ends of the connecting blocks are connected to the connecting holes. The connecting blocks are connected with fixing bolts through threads, and the two adjacent connecting blocks are fixed by connecting parts. The structure of the pile body connection is simple, and a stable connection can be made without end plates. At the same time, the connecting blocks, the steel bar connecting sleeves and the steel bars inside the pile body are an integrated structure, so that the concrete at the bolt connection will not be affected or damaged, thereby ensuring the overall performance of the pile body. However, in the use of prestressed high-strength concrete piles without end plate connection, two concrete piles are butt-jointed and then fixed with bolts at multiple points. This form has a small contact surface and is fixed only by bolts. When the bolts are rusted, the connection of the prestressed high-strength concrete piles without end plates will be broken, which reduces the butt joint stability of the prestressed high-strength concrete piles without end plates and poses a safety hazard.
