る。 The slime is gelled by being mixed with an injection material such as water glass injected into the bottom of the hole by an excavator, and solidified as a gel around the tip of the excavator. After the slime has sufficiently gelled, the gel body is discharged by pulling up the excavator.
掘削機引き上げの際、掘削孔内に孔壁保護のた
め、また浮力によるゲル体の排出を助けるために
掘削機のロツド先端部より清水、もしくはベント
ナイト等の安定液が圧入される。 When the excavator is pulled up, clean water or a stable liquid such as bentonite is forced into the excavator from the tip of the excavator's rod to protect the hole wall and to help discharge the gel due to buoyancy.
ゲル体の排出液、鉄筋篭の挿入、コンクリート
の打設により杭を形成する。 A pile is formed by draining the gel body, inserting a reinforcing bar cage, and pouring concrete.

ンクリート杭Ａを形成する方法である。 This invention is a method of forming a concrete pile A by gelling the slime at the bottom of an excavation hole with an injection material such as water glass, and treating the slime.
第１図に従つて施工手順を説明する。 The construction procedure will be explained according to Fig. 1.
まず掘削機１により所定の深さまで掘削して掘
削孔２を形成する（）。 First, an excavator 1 excavates to a predetermined depth to form an excavated hole 2 ().
続いて掘削機１のロツド１ａを通じて孔底２ａ

ることになる。 When injecting the injection material 3, if a solidifying material such as cement is mixed and kneaded with the slime 4, it is effective to promote gelation. A specific method of mixing the injection material 3 and solidification material is as follows. That is, for example, a bag containing a solidifying material is mixed into the injection material 3, and this and the injection material 3 are press-fitted into the hole bottom 2a through the rod 1a, the bag is broken by rotation of the drilling bit 1b, and the material is solidified at the hole bottom 2a. The material is mixed with the injection material 3, and then kneaded with the slime 4 by rotating the drilling bit 1b. And drilling bit 1b
The rotation of the slime 4 is stopped and the slime 4 is allowed to gel. The gel body 4' is formed around the drilling bit 1b.
スライム４のゲル化完了後、ロツド１ａを通じ
て孔底２ａに安定液５を注入しながらゲル体４′
を掘削機１とともに引き上げる（）。 After gelation of the slime 4 is completed, the gel body 4' is injected into the hole bottom 2a through the rod 1a.
