Abstract

The invention provides a pile machine special for an immersed tube pressure filling pile and a method of using the pile machine to conduct concrete pressure filling construction and reinforcing cage post inserting construction. The pile machine special for the immersed tube pressure filling pile is provided with a concrete pressure filling system and a reinforcing cage post inserting system, uses a hollow vibratory hammer, and is provided with an inner hammer. According to the pile machine special for the immersed tube pressure filling pile and the method of using the pile machine, the quality of the concrete pressure filling construction and the quality of the reinforcing cage post inserting construction can be guaranteed, the application range of the immersed tube pressure filling pile is enlarged, and good economic benefit and technological benefit are achieved.

Description

technical field [0001] The invention relates to a special pile machine for sinking and pressing grouting piles, a use method and application thereof, and belongs to the technical field of pile foundation construction. Background technique [0002] The application number is 201110172486.3, the application date is June 24, 2011, and the applicant is Bi Jiandong's Chinese invention patent: the whole process construction method of immersed tube grouting pile and its special device (hereinafter referred to as: 201110172486.3 patent), which proposes the sinking tube grouting pile The concept and method are as follows: after the sinking tube is in place, while the pile tube is pulled up, concrete is pumped through the pouring tube, and the pile is inserted into the steel cage to form a pile; and the method of test pile, pile measurement and its special device are given. [0003] The problems in the 201110172486.3 patent are: [0004] Pumping concrete is to use the concrete pump on...
