ENLARGED ENDBEARING CAPACITY FOUNDATION USING CONE WITH SCREW AND IT'S DRY PROCESS OF CONSTRUCTION WORK

摘要

The present invention relates to an extended tip support base using a cone base provided with a screw and a dry construction method thereof.;Expanded tip support foundation dry construction method using a cone base equipped with a screw of the present invention, after selecting the foundation installation location after the foundation installation ground location selection step; A hollow pipe-shaped column is installed on the upper part, and the upper part has a larger diameter than the column diameter, and is formed in the shape of a cone that gradually decreases in diameter as it goes to the lower part, and has an accommodating part therein. A grout step of preparing a cone foundation having a screw blade having a small size of a clausoid curve, and then filling grout material or concrete in the pillar and the receiving portion of the cone foundation; Conical base filled with grout material or concrete in the installation and inside the column in the installation position and then drilling the foundation to a predetermined depth by using a rotation and indentation to the self-puncture; consists of.;According to the present invention, it is made of a reinforced material such as steel (steel) or reinforced plastics, and excavates the ground by direct self-punching of a cone-based expansion base in which a grout material or concrete is filled therein, so that a predetermined quality ground can be excavated. By positioning, the expansion base can be easily installed to prevent loosening or displacement of nearby ground or structure due to excavation, and the excavation and backfilling process can be omitted, and economic expansion can be easily and easily installed. By installing the foundation with the calculated cross section, it is not only easy to secure accurate tip bearing capacity, but also the number of piles can be significantly reduced, so that the economic effect is large. Noise and vibration when installing pile foundations, The bearing capacity of the pile is increased as a whole through the positive increase of the tip bearing capacity, which prevents and reduces the bearing capacity due to rotation and indentation.;Screw, Cone Foundation, Tip Support Foundation, Pile, Grout
