Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, a pipe pile tip of the present invention comprises a pile tip plate 1, a steel pipe 2 is arranged on the pile tip plate 1, the steel tube 2 is welded to the pile tip plate 1, and the pile tip plate 1 is connected to the steel tube 2 Several stiffeners 3 are arranged at the junction of the pile, and the stiffeners 3 are welded with the pile tip plate 1 and the steel pipe 2, and the end of the steel pipe 2 away from the pile tip plate 1 is in a zigzag shape.

[0012] The working process of this example: use full welding to weld the pile tip plate 1 and the steel pipe 2 together, then use full welding to weld the stiffener 3 at the joint between the pile tip plate 1 and the steel pipe 2, and then use full welding to weld the pipe pile tip to the steel pipe 2 The pile body is welded, and the pile is sunk by hammering.

Abstract

The invention provides a pile tip of a tubular pile. The pile tip comprises a pile tip end plate, a steel tube is arranged on the pile tip end plate and welded with the same, a plurality of stiffening ribs are arranged at the joint of the pile tip end plate and the steel tube and welded with the pile tip end plate and the steel tube, and one end, away from the pile tip end plate, of the steel tube is saw-toothed. The pile tip has the advantages that an annular opening of the steel tube substitutes for a cross rock-breaking edge, rock breaking capability is higher, the annular rock-breaking opening is arranged to be saw-toothed, rock grabbing capability of the pile is further improved, the pile tip is less prone to slipping, and rigidity of the pile tip end plate and the steel tube can be further improved by the arranged stiffening ribs.

Description

technical field [0001] The invention belongs to the field of building foundation engineering, in particular to a pipe pile tip. Background technique [0002] Prestressed high-strength concrete pipe piles are widely used because of their characteristics of driving resistance, pressure resistance, strong penetration, high vertical bearing capacity of single piles, good seismic performance, low cost, and short construction period. Most of the pile foundations are The pebble layer, gravel sand layer, and strongly weathered mudstone layer are the bearing layers of the end piles. Whether the depth into the bearing layer of the end piles meets the design requirements is closely related to the type of pile tip. For the case of strongly weathered rock as the bearing layer of the end pile, when a cross-shaped pile tip with a strong rock-breaking ability is used, it is found that rotten piles and large pile position deviations are prone to occur.
