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 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 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 coordinate system i...

Abstract

The invention provides a static pressure pile machine with a pile positioning system and a pile construction method, relates to the technical field of geotechnical engineering, and can improve the positioning and installation accuracy of the pile. The static pressure pile machine has a first outrigger, a second outrigger, a support cylinder, a workbench, a pile holder, a crane frame, a counterweight and a positioning system. The first outrigger and the second outrigger are arranged in parallel, and multiple supports The oil cylinders are set above the first leg and the second leg respectively, the workbench is fixed above the support oil cylinder, the crane frame is set above the workbench, the pile holder is set in the center of the workbench, and there are multiple accessories on the workbench. Heavy; The positioning system includes a hoisting positioning device, a pile hole positioning device and a column pile correction positioning device. And the method for using the static pressure pile machine to construct piles, including positioning and hoisting the first pile, positioning the pile hole after installing the pile tip, and using the second pile to correct the position of the first pile during the static pressure pile down process; The construction of the static pressure pile machine improves the construction quality of the pile foundation and ensures the construction safety.

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...
