Conical concrete pile tip, tubular pile provided with pile tip and production method of tubular pile

Abstract

The invention discloses a conical concrete pile tip, which is characterized in that the pile tip is a conical pile tip formed by pouring a pile tip body through concrete, wherein the pile tip body comprises a locating plate arranged at the end part of a small head of a circular table, a hole is arranged in the middle of the locating plate, a plurality of side ribs of the pile tip are uniformly fixed on the locating plate to form a conical skeleton of the pile tip body, and the ends of the side ribs of the pile tip are fixed on the locating plate; a bending part used for pouring to form a connection transition section of the pile tip and a pile body is arranged at the tail part of each of side ribs of the pile tip, and each bending part is parallel to a central shaft of the pile tip. The invention further discloses a tubular pile provided with the pile tip and a production method of the tubular pile. The tubular pile provided with the pile tip has the advantages of convenience for transportation, strong penetrating power, good integrity, simple production process of the tubular pile and low cost; the concrete pile tip replaces a steel pile tip, so that the concrete pile tips are integrally connected during molding of the tubular pile, and thus a welded connection process for the steel pile tip is omitted and a large amount of steel resources are saved; the tubular pile is suitable for requirements on different engineering and geological conditions.

Description

technical field [0001] The invention relates to a prestressed high-strength concrete pipe pile used in the building material industry, in particular to a conical concrete pile point, a pipe pile with the pile point and a manufacturing method of the pipe pile. Background technique [0002] Since the prestressed concrete pipe pile was introduced from Japan to my country in the early 1990s, it has been rapidly promoted in the north and south of the river because of its advantages of reliable quality, low engineering cost, and fast construction speed. Prestressed concrete pipe pile foundation has become the main pile type of civil construction pile foundation in economically developed areas. [0003] At present, the traditional domestic steel pile tip is separated from the pile body, and is connected by welding during construction. At present, the country or industry has no technical specifications for the connection between the steel pile tip and the pile body, and the bearing ...

AI Technical Summary

Problems solved by technology

The quality of picket piles and welding used in existing projects is uneven, which affects the quality of pile foundations, especially in geological conditions with hard interlayers and dense sand layers, it will be difficult to sink piles and there will be many rotten piles

[0004] The existing concrete pile tip is mainly conical, and the tip of the cone is prone to inclination when it is inserted into the ground during the construction process, and the force-bearing area of ​​the tip of the cone is small, especially when the bearing layer is a rock surface, it is too small to bear The area is easy to cause the pile tip to be broken, which directly affects the quality of the project
