Definitions
- the present invention relates to the field of civil engineering, and in particular, to the structure of a pile.
- the construction method of piles to form the foundation of the structure on the ground can be largely divided into the method of entering the factory manufacturing pile by driving, and the method of installing the reinforcement in the drilling hole and placing the concrete in the field.
- the former anti-punching method uses hollow pipes or PHC piles with hollow pipes formed with upper and lower ends as piles.
- soil is introduced through the lower trenches, and consolidation is applied to the lower ground at some point. As no more inflow of soil occurs (expressing 'floor clogging' in the field), a stable foundation can be formed.
- This anti-taking method has the advantage of excellent construction convenience and stability of the structure, but has the disadvantage that a large noise generated by the driving during construction.
- the resistance is calculated to be about 30% less than that of the driven pile, so the construction cost increases because the number of piles must be increased when applying the method of constructing the airport airport pile.
