Embodiment 1

[0028] A construction method for piles, comprising the steps of:

[0029] (1) In place: place the appearance of the equipment on the set pile position;

[0030] (2) Sink the outer tube to the set depth; the method of sinking the tube is:

[0031] (a) Inner rammed earth body: Lift the inner ramming hammer inside the outer tube to move up and down, and punch the soil or pile body under the outer tube to form a shear opening;

[0032] (b) Sinking of the outer tube: the outer tube sinks by at least one of the following methods: ①Under the weight of the outer tube, the outer tube sinks along the shear opening by gravity; ②Activate the back pressure or static pressure device on the outer tube, The outer tube sinks under pressure along the shear opening; ③Start the vibration device on the outer tube, and the outer tube vibrates and sinks along the shear opening; ④Start the vibration and pressure device on the outer tube at the same time, and the outer tube vibrates along the shear o...

Embodiment 2

[0044] A construction method for piles, comprising the steps of:

Abstract

The invention discloses a construction method for piles. The method comprises the steps of positioning, pipeline sinking, rammed forming, casting molding, tube drawing forming, and the like. The method disclosed by the invention is small in construction noise, has little effect on environment, good environmental conservation capability, reliable construction quality and good pile quality; and by using the method, a multilevel expansion head can be formed.

Description

technical field [0001] The invention relates to a pile construction method. Background technique: [0002] The existing construction technology of immersed tube grouting piles and rammed piles generally adopts diesel hammer or vibratory hammer technology, which has large construction noise and vibration, and has a great impact on the surrounding environment, which has some unsatisfactory features. Invention content: [0003] The purpose of the present invention is to provide a pile construction method with good environmental protection, good cost performance and reliable quality. [0004] Technical solution of the present invention is: [0005] A pile construction method is characterized in that: comprising the following steps: [0006] (1) In place: place the appearance of the equipment on the set pile position; [0007] (2) Sink the outer tube to the set depth; [0008] (3) Tamping and expanding forming: Lift the inner rammer in the outer tube, put the filler into th...
