Problems solved by technology

[0003] When the existing static pile machine is pressing the pile, the foundation soil will be strongly disturbed, especially in the seaside, frozen soil layer, weak soil layer and geological structural belt with complex geological conditions, the soil around the pile is resistant to shearing. There is a large difference between the strength and the shear strength of the pile

Embodiment Construction

[0034] combine Figure 1 to Figure 6 As shown, a specific implementation of a static pressure pile machine with a pile positioning system and a pile construction method provided by the present invention will be described.

[0035] A static pressure pile machine with a pile positioning system, comprising a first outrigger 1, a second outrigger 2, a support cylinder 3, a workbench 4, a pile holder 5, a crane frame 6, a counterweight 7 and a positioning system , the various structures cooperate with each other to smoothly hoist the pile, and can accurately locate the axis of the pile hole to ensure that the pile sinks along the axis of the pile hole. When the pile body is inclined, the positioning device can also be corrected by the pile, and the inclined The piles are corrected. The first outrigger 1 and the second outrigger 2 are arranged in parallel to ensure the overall stability of the static pile machine, and it is convenient to carry out satellite positioning, and a coord...

Abstract

The invention provides a static pressure pile machine with a column pile positioning system and a column pile construction method, and relates to the technical field of geotechnical engineering. The static pressure pile machine is provided with a first supporting leg, a second supporting leg, a plurality of supporting oil cylinders, a workbench, a pile holding device, a crane frame, a plurality ofcounterweights and the positioning system. The first supporting leg and the second supporting leg are arranged in parallel. The supporting oil cylinders are arranged above the first supporting leg and the second supporting leg respectively. The workbench is fixed to the upper portions of the supporting oil cylinders, the crane frame is arranged on the workbench, the pile holding device is arranged in the center of the workbench, and the counterweights are disposed on the workbench. The positioning system comprises a hoisting positioning device, a pile hole positioning device and a column pilecorrection positioning device. The column pile construction method using the static pressure pile machine comprises the steps that a first column pile is positioned and hoisted, a pile hole is positioned after a pile tip is installed, and the position of the first column pile is corrected through a second column pile in the static pressure piling process. The static pressure pile machine improvesthe pile foundation construction quality and ensures the construction safety during construction.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a static pile driver with a pile positioning system and a pile construction method using the static pile driver. Background technique [0002] The static pile driver is the equipment used for pile foundation construction in geotechnical engineering. The pile pressure mechanism of the static pile driver uses the self-weight of the pile and the counterweight on the frame to provide a reaction force to press the prefabricated pile into the soil. The static pressure pile driver does not need hammering, so it will not generate vibration, noise pollution, and will not generate impact force to ensure the integrity of the pile. [0003] When the existing static pile machine is pressing the pile, the foundation soil will be strongly disturbed, especially in the seaside, frozen soil layer, weak soil layer and geological structure belt with complex geological conditions, th...
