For example, in the lifting of the pile (S230), when the lift (1) is magnetically attached to the PHC pile (20) in an electromagnet type or a permanent magnet type according to the activation of the magnetic force of the lift (1), the lift (1) In a state in which the PHC pile 20 is supported by using the magnetic attachment force of the PHC pile 20, it is lifted while gradually standing vertically by the lifting operation of the heavy equipment 10, and when the PHC pile 20 is completely vertically erected, the heavy equipment 10 is Prepare for inserting the PHC file 20 by moving it to the drilling hole.

And, the file insertion step (S240) is;

After the pile lifting step, it is a process for inserting the lifted PHC pile 20 into the drilling hole.

For example, the file insertion step (S240) is; The PHC pile 20, which is attached with a magnet through the magnetic force of the lift 1 and is lifted vertically, is slowly lowered into the drilling hole using the heavy equipment 10 to be inserted to the insertion depth of the PHC file 20.

And, the file separation step (S250) is;

After the file insertion step, when the insertion of the PHC file 20 into the drilling hole is completed, the lift 1 is separated from the PHC file 20 after an operation to remove the magnetic force of the lift 1 to complete the operation. It is a process for

For example, the file separation step (S250) is an OFF operation of inactivating the magnetic force of the lift 1 attached to the PHC file 20 when the insertion of the PHC file 20 into the drilling hole is completed. lift) can be separated from the PHC file 20, and the operation of the lift 1 is an electromagnet type according to the method in which the magnetic force is deactivated. In the case of a permanent magnet (magnetic) type, the second remote control 260 is operated to be controlled by the second control unit 250 .

At this time, when the lift 1 is separated from the PHC pile 20, the construction of the PHC pile 20 is completed once, and the PHC pile 20 is continuously constructed while repeating the above-described process steps, and the foundation ground work is carried out. do.

Here, in the pile preparation step (S210), a joint plate for connecting the PHC piles 20 is installed at one end of the PHC pile 20, and the PHC pile 20 in which the joint plate is installed is attached to the lift attachment step, the pile It further includes; a file connection step (S260) of connecting to the PHC file 20 inserted into the drilling hole through the lifting step, the file insertion step, and the file separation step.

The pile connection step (S260) is a process for vertically connecting a plurality of PHC files 20 according to the corresponding depth of the ground work and inserting them into the drilling hole, and when the PHC file 20 is first inserted into the drilling hole , when the insertion of additional PHC piles 20 is requested according to the depth corresponding to the foundation ground work, a plurality of PHC piles 20 are interconnected using a joint plate mounted on the PHC pile 20 in advance in the pile preparation step. make it

To this end, when the file connection step (S260) starts, the PHC file 20 equipped with a joint plate is lifted to the side of the drilling hole in the pile lifting step and moved, and the moved PHC file 20 in the file insertion step (S240) ) is inserted adjacent to the PHC file 20 inserted into the drilling hole, and then the PHC files 20 are interconnected using the joint plate, and when the PHC files 20 are interconnected as described above, in the file separation step Remove the lift (1) to complete the pile connection process.

At this time, if the lift 1 is separated from the PHC pile 20 while the connection of the PHC pile 20 is completed, the connection construction of the PHC pile 20 is completed once and the process of the above-described pile connection step is repeated while a plurality of Continuous connection work can be performed according to the conditions that require the PHC file 20 of the.

Here, the construction method of the PHC pile is a method of installing and supplying manila shoes at both ends of the PHC pile 20 in the production plant of the PHC pile 20, and an iron plate at one end of the PHC pile 20 in the production plant. It is possible to choose between a method of attaching and supplying a steel plate and a method of attaching and supplying an iron plate to the PHC pile 20 at the construction site, and the iron plate attached to the PHC file 20 at the construction site is the PHC file after construction is completed. It can be isolated from (20).

On the other hand, although the present invention has been shown as a basic form applied to the PHC pile 20, it can be applied to all types of piles constructed in the ground, such as steel pipe piles and H-beams for foundation ground construction, in this case magnet attachment By combining the steel plate for the steel pipe pile, H-beam, etc. with one end of the pile, magnet attachment can be performed.

As described above. Although the present invention has been expressed with descriptions and drawings illustrating specific preferred embodiments, the terms used herein are for easy explanation of the present invention, limiting the meaning of these terms, or limiting the scope of the claims not to do it,

The present invention is capable of various changes, alterations, modifications, etc. by those of ordinary skill in the art to which the invention pertains within the scope that does not depart from the spirit and scope of the invention indicated by the claims according to the above embodiments.
