Concrete pipe pile convenient for field construction

Abstract

The invention discloses a concrete pipe pile convenient for field construction. The concrete pipe pile convenient for field construction comprises a pipe pile body; a pressure spring I is fixedly connected to the top of the pipe pile body; a bushing is fixedly connected to the top of the pressure spring I; the inner wall of the bushing is connected with the surface, close to the top, of the pipe pile body in a sliding mode; a fixing disc is fixedly connected to the inner wall of the pipe pile body; a shaft I is rotationally connected to the inner wall of the pipe pile body in a fixed-axis mode; a gear I fixedly sleeves the surface of the shaft I; a toothed plate is meshed with the rear side of the gear I; and a transmission rod is fixedly connected to the top of the toothed plate. According to the concrete pipe pile convenient for field construction, in the actual use process, due to the fact that a traditional pile tip mostly enters soil by being hammered by a pile driver during use,it is difficult to actively conduct auxiliary excavation operation on the soil, the resistance of the soil to the pile tip is increased along with increasing of the depth of the pile tip entering thesoil, pile driving operation is further hindered, and inconvenience is brought to use.

Description

technical field [0001] The invention relates to the technical field of prefabricated pipe pile components, in particular to a concrete pipe pile convenient for on-site construction. Background technique [0002] Concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles. Pretensioned prestressed pipe pile is a hollow cylindrical slender concrete prefabricated component made by pretensioned prestressing process and centrifugal forming method. It is mainly composed of cylindrical pile body, end plate and steel ferrule; Generally refers to the pile tip of the prestressed pipe pile, which is used for the construction of the prestressed concrete pipe pile foundation. During the construction of engineering prefabricated piles, the pile tip is welded at the pile head position, and the pile body enters the soil layer to avoid damage to the pile head and pile body inclination (perpendicularity control), and can better enter ...

[0003] However, in the actual use process, since the traditional pile point is mostly relying on the hammering of the pile driver to penetrate the soil, it is difficult to actively carry out auxiliary excavation operations on the soil, and with the deepening of the depth into the soil, it will make The resistance of the soil to the pile tip is also increased, which further hinders the piling operation and brings inconvenience to the use
