Pre-tensioned prestressing high-performance concrete pipe pile

Abstract

The invention discloses a pre-tensioned prestressing high-performance concrete pipe pile. The pre-tensioned prestressing high-performance concrete pipe pile comprises a pipe pile body and a pile cover. The pile cover is arranged on the top of the pipe pile body; an outer protecting sleeve is arranged on the inner wall of the pipe pile body; a cavity is formed in the inner wall of the outer protecting sleeve; a plurality of supporting structures are arranged in the cavity and each composed of an outer frame, an inner cavity and an inner frame; a plurality of grooves are formed between the innerwalls of the outer frames and the inner cavities; the grooves are internally provided with supporting devices correspondingly; the supporting devices are internally provided with bases; sixth clamping blocks are arranged on the two sides of the top of each base correspondingly; fifth clamping blocks are arranged on the tops of the sixth clamping blocks correspondingly; supporting rods are arranged on the tops of the fifth clamping blocks correspondingly; fourth clamping blocks are arranged on the tops of the supporting rods correspondingly; and third clamping blocks are arranged on the tops of the side edges of the fourth clamping blocks correspondingly. The pre-tensioned prestressing high-performance concrete pipe pile has the beneficial effects that supporting force of the pipe pile isimproved, the service life of the pipe pile is prolonged, and the working efficiency of the pipe pile is improved.

Description

technical field [0001] The invention relates to the technical field of concrete pipe piles, in particular to a pretensioned prestressed high-performance concrete pipe pile. Background technique [0002] Pre-tensioned prestressed pipe pile is a hollow cylindrical slender concrete prefabricated component made by pre-tensioned prestressing process and centrifugal forming method. It is mainly composed of cylindrical pile body, end plate and steel ferrule. The code name of the stress high-strength concrete pipe pile is PHC. The pipe pile is divided into 300mm, 350mm, 400mm, 500mm, 600mm, 800mm and 1000mm according to the outer diameter. The actual production diameter is 300mm, 400mm, 500mm and 600mm are the main ones. The existing concrete pipe piles have low driving resistance. When the pile head encounters rock or hard soil layer, the pile head will be damaged or the pile will be broken. The penetration is poor and the support performance is weak, which makes the pipe pile Th...
