Method and device of immersed tube pile planting and utilization method of device

Abstract

The invention provides two immersed tube pile planting methods for planting a precast pile after pulling out an immersed tube, a double-pile clamping box static pile pressing machine matched with themethods, and a utilization method of the double-pile clamping box static pile pressing machine. Compared with a conventional immersed tube pile planting method for planting the precast pile before pulling out a sleeve, the immersed tube pile planting methods have the advantages that operation is easier and safer, and construction efficiency is higher.

Description

technical field [0001] The invention relates to a method and a device for planting piles by sinking tubes and a use method thereof, and belongs to the technical field of pile foundation construction. Background technique [0002] Most of the existing pile planting methods are drilling piles or inserting prefabricated piles into cement soil. The piles are basically friction piles, and the bearing capacity of the pile tip is low, so it cannot play the role of a hard bearing layer. [0003] The method of pipe sinking pile planting provided by the invention patent with application number 201810392395.2 is to implant prefabricated piles in the sinking tube. The following problems in operation may lead to the failure of pipe sinking pile planting: [0004] (1) Because this type of pile is generally an end-supported pile, the length of the pile is unknown in advance, and the length of the immersed tube is fixed, so the height of the immersed tube exposed to the ground or the operat...

Problems solved by technology

[0004] (1) Because this type of pile is generally an end-supported pile, the length of the pile is unknown in advance, and the length of the immersed tube is fixed, so the height of the immersed tube exposed to the ground or the operating surface is also unknown. When the exposed height is large , it is difficult to carry out pile recognition operation;

[0005] (2) Due to the reason (1), and the gap between the prefabricated pile and the sinking tube is small, it is difficult to recognize the prefabricated pile into the casing;
