Problems solved by technology
[0002] At present, with the acceleration of urban construction and development, most of the original public facilities can no longer meet the needs of use, especially in urban transportation and housing construction. It is necessary to renovate and expand the original buildings. In the process, both inevitably involve the removal of underground pile foundations
However, due to the characteristics of urban reconstruction, there are often other buildings and obstacles nearby. In demolition and construction sites, there are often many obstacles. Large equipment such as pipe drilling rigs and cranes used in conventional pile extraction techniques cannot enter the construction site. After the site is cleaned up, large equipment such as cranes can enter the construction, which delays the construction progress and wastes manpower and material resources

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0020] As shown in the figure: in a kind of construction method of extracting piles of the present invention, tripod 1, pipe drill head 2, drill pipe 3, old pile foundation 4, movable pulley 5, angle steel ground pile 6, wire rope cover 7, forklift 8.
[0021] A construction method for extracting piles of the present invention comprises the following steps:
[0022] A. Preparations before pulling piles:
[0023] Select the tonnage of forklift 8 according to the weight of old pile foundation 4, forklift 8 is arranged on old pile foundation 4 limits; Seam steel pipe is made, and its wall thickness and height are decided according to the depth of the old foundation pile 4 that prepares to pull out, and tripod 1 is provided with base, and described base is fixed with ground by expansion bolt. The movable pulley 5 is installed at the center of the tripod 1, the ...

The invention discloses a pile pulling construction method which comprises the following steps of: A, preparing before pulling a pile; B, separating an old pile foundation; and C, pulling the pile. The pile pulling construction method has the advantages that the pile pulling construction method has low requirements on the construction site and has high construction efficiency; the pile pulling construction method is safe and reliable to use, has low disturbance to surrounding soil mass, has low noise, has no vibration and has no pollution; and operability is strong, large-scale equipment such as a crane and the like is not required, and construction cost is reduced.
Description
technical field [0001] The invention relates to a construction method for pulling out old foundation piles in the field of construction engineering, and more specifically relates to a construction method for pulling out piles with low noise and simple construction. Background technique [0002] At present, with the acceleration of urban construction and development, most of the original public facilities can no longer meet the needs of use, especially in urban transportation and housing construction. It is necessary to renovate and expand the original buildings. In the process, both inevitably involve the removal of underground pile foundations. However, due to the characteristics of urban reconstruction, there are often other buildings and obstacles nearby. In demolition and construction sites, there are often many obstacles. Large equipment such as pipe drilling rigs and cranes used in conventional pile extraction technology cannot enter the construction site. After the s...
