【発明の詳細な説明】
本願発明は基礎杭に関し、特に中空杭からなる基礎杭に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foundation pile, and particularly to a foundation pile consisting of a hollow pile.
従来、コンクリート杭を上方からハンマーなどにより衝
撃を加えて土中に打ち込むことにより基礎杭を打設して
きたが、近年は部会地の密集住宅地ででも建設作業が必
要となり、衝撃音が周囲に伝わることが事実上許されな
くなってきた。その結果は、音が出ない工法の開発が必
要となり、種々の技術が開発されてきている。しかし、
いまだ十分な成果をあげていない。Traditionally, foundation piles have been driven by impacting concrete piles from above with hammers and driving them into the soil, but in recent years, construction work has become necessary even in densely populated residential areas, and impact noise can be heard in the surrounding area. In fact, it is no longer allowed to be communicated. As a result, it has become necessary to develop construction methods that do not emit noise, and various technologies have been developed. but,
We have not yet achieved sufficient results.
本願発明は上記の問題点を解決することを目的とするも
のである。The present invention aims to solve the above problems.
次に、上記目的を達成するための具体的構成を図面に従
い説明すると、中空杭本体１の先端部２を封じ、その先
端部２の円錐状部分の先端から所望の傾斜方向に刃部３
を形成し、前記中空杭本体１の周側面部に翼片を立設さ
せ、その翼片を螺旋状翼片４に形成してなる基礎杭であ
る。Next, a specific configuration for achieving the above object will be explained with reference to the drawings. The tip 2 of the hollow pile body 1 is sealed, and the blade 3 is moved from the tip of the conical portion of the tip 2 in a desired inclination direction.
This is a foundation pile in which wing pieces are erected on the circumferential side of the hollow pile main body 1, and the wing pieces are formed into spiral wing pieces 4.
次に、上記構成から生じる作用効果を述べると中空杭本
体の先端に刃部を設けたので、土中を容易に掘進しつる
効果がある。Next, to describe the effects resulting from the above configuration, since the blade portion is provided at the tip of the hollow pile main body, it has the effect of easily digging through the soil.
また、杭本体が中空であるので、比較的軽く、かつ強度
的にすぐれており、かつ杭本体の上端部を他の部材によ
り把持し易い効果がある。Furthermore, since the pile body is hollow, it is relatively light and has excellent strength, and the upper end of the pile body can be easily held by other members.
また、翼片を杭本体の周側面部に設けたので、杭を埋設
後、周囲の土に対し安定させつる効果がある。In addition, since the wing pieces are provided on the peripheral side of the pile body, after the pile is buried, it has the effect of stabilizing the pile against the surrounding soil.
また、翼片を螺旋状に巻回させたので杭を旋回させるこ
とにより簡単に土中に埋設させつる効果がある。In addition, since the wing pieces are spirally wound, the pile can be easily buried in the soil by turning the pile.
