Embodiment 1

[0012] Embodiment 1: with reference to attached figure 1 . 1. An assembled deformable pile, which includes a pipe pile. The pile body of the pipe pile 1 is provided with more than one groove 2, and the pipe pile bearing support ring wing 3 is installed in the groove 2. The inner ring of the supporting ring wing 3 of the pipe pile is a boss ring and matches with the groove 2 on the pile body. The width of the opening of the groove 2 is greater than the bottom of the groove. The upper surface of the pipe pile bearing support ring wing 3 is a plane, and the lower surface is an inclined surface. The supporting ring wing 3 of the pipe pile is a butt joint structure of two halves, and the butt joint surfaces of the two halves are connected by bolts or mechanically.

Embodiment 2

[0013] Embodiment 2: with reference to attached figure 2 . On the basis of Embodiment 1, the bottom of the pipe pile is equipped with a wing-shaped pile tip or an opening or a belt tip 4 .

Embodiment 3

[0014] Embodiment 3: On the basis of Embodiment 1 or 2, an assembly method of a prefabricated deformed pile, (1) When the geological condition of the pile is soft soil or sandy soil, select the pipe according to the friction coefficient of soft soil or sandy soil. The diameter of the pile bearing support ring wings 3 and the number of pipe pile bearing support ring wings 3 required for each pile, and then the pipe pile bearing support ring wings 3 are nested in the grooves of the pile body; (2) when the pile is pressed When the condition is hard soil, select the diameter of the supporting ring wings 3 of the pipe piles and the number of supporting ring wings 3 required for each pile according to the bearing friction coefficient of the hard soil, and then nest the supporting ring wings 3 of the pipe piles in the groove of the pile. The arrangement of the support ring wings 3 of the pipe piles with different diameters gradually decreases from top to bottom according to their dia...

Abstract

The invention relates to an assembly type deformable pile and an assembling method thereof. According to the invention, pile wings of a pile body of the assembly type deformable pile can be adjusted according to geological conditions of the pressed (driven) pile. The assembly type deformable pile comprises a tubular pile, wherein the pile body of the tubular pile is provided with more than one groove, tubular pile bearing and supporting ring wings are arranged in the grooves, and dimension of the tubular pile bearing and supporting wings can be changed. The assembly type deformable pile has the advantages that: a precedent of changing the pile wings while keeping the pile body unchanged is created, the tubular pile bearing and supporting ring wings with different diameters can be arranged on the same tubular pile, the assembly type deformable pile can be pressed (driven) under different geological conditions, a tubular pile manufacturing mould is greatly simplified, production cost of the tubular pile is reduced, and bearing capacity of the tubular pile is greatly improved.

Description

technical field [0001] The invention relates to an assembled deformed pile and an assembly method capable of adjusting the pile wings of the pile body according to the geological conditions of the pressed pile (pile driving), and belongs to the field of pipe pile manufacturing. Background technique [0002] The applicant owns CN 1644803C, named "rib-shaped tubular pile", which includes a pile body, the pile body is provided with reinforcing ribs, and the outer wall of the pile body has longitudinally protruding ribs. Advantages: The design of longitudinal ribs on the outer wall of the pipe pile not only effectively expands the effective supporting area of ​​the overall pipe pile and improves the bearing capacity of the pipe pile, but also effectively reduces the pressure of the pipe pile while ensuring that the bearing pressure of the pipe pile remains unchanged. The pile depth greatly reduces the difficulty and cost of pile pressing for tubular piles. [0003] All CN 10114...
