ENLARGED ENDBEARING CAPACITY FOUNDATION USING CONE WITH SCREW AND IT'S WET 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 wet construction method thereof.;Expanded tip support base wet 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; 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. Small cone-shaped screw blades are installed, and the cone foundation, which has grout hoses for filling grout material or concrete, is installed at the installation location. Perforating step of drilling to a predetermined depth by using a rotation and indentation; After grouting by reaching the predetermined depth through the grout hose through the grout material and concrete grout to grind the interior of the column and the interior of the cone base with grout material or concrete to complete the foundation; consists of.;According to the present invention, the ground of the cone shape made of a reinforced material such as steel (steel) or reinforced plastics is directly excavated with the self-puncture to place the ground on a predetermined good ground, and then grout inside the base of the cone shape. By filling the grout, such as cement mortar, to facilitate the installation of expansion foundations to prevent the occurrence of loosening or displacement of nearby ground or structure due to excavation, the excavation and backfilling process is omitted, economical and easy It is possible to install the enlarged foundation, and to install the foundation with the pre-calculated cross section, it is not only easy to secure accurate tip bearing capacity, but also the number of piles can be significantly reduced. It can easily secure the bearing capacity of pile foundations and do not apply the driving force from the outside. Therefore, the pile foundation can be prevented from noise or vibration, and the ground is relaxed due to rotation and indentation, and the bearing capacity of the pile is reduced.;Screw, Cone Foundation, Tip Support Foundation, Pile, Grout
