てソイルコンクリート杭とすることもある。An earth auger is used in the excavator, and the auger screw is rotated to remove earth and sand upward while drilling the hole.When the auger screw is reversed and pulled out, cement milk, mortar, etc. is injected from the tip of the screw to create a fill-in-place mortar. Methods of constructing piles are well known. in this case,
Soil concrete piles are sometimes made by mixing cement milk, mortar, etc. with a portion of the excavated soil.

ることができる。(In terms of strength, it is not necessary to insert H-shaped steel 2 in all areas.) By the way, in order to create such column row piles, a multi-axis auger such as a 3-axis machine or a 4-axis machine is used to If piles are excavated all at once, construction can be done more quickly and easily than when building piles one by one using a single-shaft auger.

きわめて面倒で手数を要するものであった。However, in this way, construction using a multi-axis auger 1
In this case, the main pile 1a and the other piles 1 have the same diameter and the same surface position, so for example, the exposed surface of the flange of the H-shaped steel 2 in the main pile 1a is used as the main material for cutting and tensioning. In order to fix the steel material 3 to be used, mortar etc. must be scraped off laterally not only on the main pile 1a but also on the sides of other piles l.
It was extremely troublesome and time-consuming.

A multi-axis earth auger is used which is offset from the front or rear relative to other auger rods, and the parent pile into which steel materials such as H-type steel are to be inserted is centered in front or rear relative to the other piles using the specific auger rod. Form this at an appropriate number of intervals by shifting the piles, and when excavating after pile construction, scrape off the side of the parent pile to expose the steel surface, and fix the steel material for the horizontal structure, such as recessed timber, to this exposed part. This is achieved by
以下、図面について本発明の実施例を詳細に説明する。Embodiments of the present invention will be described in detail below with reference to the drawings.
