Example Embodiment

[0041] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0042] A construction method for a vibrating immersed tube crushed stone grouting pile of the present invention comprises the following steps:

[0043] (1) Vibration sinking: According to the pre-determined pile position, the vibrating sinking pile driver is used to vibrate and sink the pile tube to a predetermined depth, that is, the design pile bottom elevation;

[0044] (2) Place steel cage and grouting pipe: place a steel cag...

Abstract

The invention relates to a construction method for a vibration sinking pipe crushed stone grouting pile, which is a new method which integrates foundation treatment and deep foundation construction process into a whole and comprises the steps as follows: (1) sinking pipe is vibrated; (2) a reinforcing cage and an injection pipe are placed; (3) crushed stone is poured; (4) the pile is formed by pulling the pipe under vibration; (5) a drainage ditch is excavated; and (6) the pile is formed by injection. The method solves the problem that the prior art can not be compatible with the foundation treatment and deep foundation construction and makes up the shortages of the prior art.

Description

technical field [0001] The invention belongs to the technical field of building construction, specifically relates to the field of building foundations and foundation construction, and discloses a construction method of vibrating tube-immersed gravel grouting piles, which is a new construction method integrating foundation treatment and deep foundation construction techniques. Background technique [0002] There are 3 kinds of construction methods close to the present invention in the engineering field at present, and one is a bored tree root pile, and its two is a crushed stone pile, and its three is a vibrating sinking pipe cast-in-place pile, which is now described as follows: [0003] 1. Drilled tree root pile [0004] The construction method is to use a drilling rig to drill a hole in the soil layer, use mud to protect the wall, and after the hole is formed, put a steel cage in the hole and put a grouting pipe in the middle of the steel cage, then fill it with gravel, a...
