本発明は撤去可能なアースアンカーにち−いて、アンカ
一体を破砕可能とし、その位置（・て釦いて後日工事す
る際、埋め殺されたアンカ一体が邪魔にならないように
したものである。[Detailed Description of the Invention] The present invention has a removable earth anchor, which allows the whole anchor to be broken, so that the buried anchor does not get in the way when construction is done later by pressing the button. This is what I did.
（従来技術と本発明の目的）
この種アースアンカーの従来技術としては次のようなも
のが挙げられる。(Prior Art and Object of the Present Invention) Examples of the prior art of this type of earth anchor include the following.
（１） ドイツ特許第１４８４５７２号この公知文献
のアースアンカーはアンカ一体がグラウト材料の注入硬
化によって形成された硬化帯の中に存在する。(1) German Patent No. 1 484 572 In the earth anchor of this known document, the anchor is present in a hardening zone formed by pouring and hardening a grouting material.
そしてこのアンカ一体の下端に位置するねぢ込み口に分
離可能に結合された引張部材によって、アンカ一体は圧
縮力を受けろ。The anchor unit is subjected to a compressive force by a tension member that is separably connected to a sink hole located at the lower end of the anchor unit.
しかしてこのアンカ一体は長い１本の円筒状となってい
る。However, the entire anchor is in the form of a long cylinder.
（２） ドイツ特許第１１０４９０５号この公知技術
のアースアンカーは前記の場合とは逆に、引張部材がア
ンカ一体の上端のねぢ込み口に分離可能に結合されてい
るので、アンカ一体は引張部材により引張力を受ける。(2) German Patent No. 1104905 Contrary to the above-mentioned case, in the earth anchor of this known art, the tension member is separably connected to the screw-in opening at the upper end of the integral anchor, so that the integral anchor is connected to the tension member. is subjected to tensile force.
しかしてこの場合のアンカ一体も長い１本の円筒状とな
っている。However, the anchor in this case also has a long cylindrical shape.
これら公知のアースアンカーにおいてはそのアンカ一体
は長い１本の円筒体であるため、その引張部材が撤去さ
れた後、アンカ一体が１本の長い円筒体となって埋め殺
されることになる。In these known earth anchors, the entire anchor is a single long cylindrical body, so after the tension member is removed, the entire anchor becomes one long cylindrical body and is buried.
したがってこの工事の行なわれた領域内で、再び工事の
行なわれるときには、この埋め殺されたアンカ一体が工
事の邪魔になる。Therefore, when construction is to be carried out again in the area where this construction was carried out, this buried anchor will become an obstacle to the construction.
したがってこのアンカ一体を撤去しなければならないが
、長い１本の円筒体のアンカ一体を撤去することは多大
の経費と手数を要することになる。Therefore, this anchor must be removed, but removing a long cylindrical anchor requires a great deal of expense and effort.
本発明はこのような従来技術の問題点を解決することを
目的とする。The present invention aims to solve these problems of the prior art.
すなわち、本発明は実施例の説明にわいて述べるように
、アンカ一体３，８が予め定められた破砕点にあ・いて
、横方向から加えられた力により、破砕可能にしたもの
である。That is, in the present invention, as described in the description of the embodiments, the anchors 3 and 8 are placed at a predetermined crushing point and can be crushed by a force applied from the lateral direction.
本発明はこのように構成することにより、アンカ一体の
埋め殺された位置にあ・いて再び工事の行なわれた場合
、アンカ一体３，８が容易に破砕されアンカ一体３，８
の位置にち−ける再工事に支障のないようにしたもので
ある。By configuring the present invention in this manner, when construction is carried out again after the anchor unit is located in a buried position, the anchor units 3 and 8 are easily crushed and the anchor units 3 and 8 are
This was done so that there would be no hindrance to re-construction at the location.
実施例の説明 以下図面に基づいて本発明の実施例について説明する。Description of examples Embodiments of the present invention will be described below based on the drawings.
第１図に示すアースアンカーの引張部材１はねぢ込み口
５の部分を除き、シース２によって保護されている。The tensile member 1 of the earth anchor shown in FIG.
アンカ一体３は溶接部７によって相互に、結合された波
形管の短管６からなる。The anchor unit 3 consists of short pipes 6 of corrugated tubes connected to each other by welds 7.
短管６は一般には鋼管で作られるが、コンクリートで作
られる場合もある。The short pipe 6 is generally made of a steel pipe, but may also be made of concrete.
アンカ一体３はグラウト材料の注入硬化によって形成さ
れた硬化体４の中に存在する。The anchor body 3 is present in a hardened body 4 formed by pouring and hardening the grout material.
第１図のアンカ一体３の短管６，６・・・・・・は引張
部材１の引張りによって最下端に位置するねぢ込み口５
から圧縮力を受ける。The short pipes 6, 6, . . . of the anchor unit 3 shown in FIG.
receives compressive force from
地中に残っているアンカ一体３は、引張部材１を取外し
た後は硬化体４に対して作用する横方向からの衝撃力に
よって容易に破砕することが出来る。After the tension member 1 is removed, the anchor unit 3 remaining underground can be easily crushed by a lateral impact force acting on the hardened body 4.
なぜなら、もろい溶接部７はこの様な衝撃力に耐え得な
いからである。This is because the fragile weld 7 cannot withstand such impact force.
それ故、たとえばアンカ一体３の位置に地中壁の溝を掘
削するときは、アンカ一体３は溶接部７を分離点として
短管６゜６がバラバラに掘削機などによって分離される
。Therefore, for example, when excavating a trench in an underground wall at the location of the anchor block 3, the anchor block 3 is separated into short pipes 6.degree. 6 using the welded portion 7 as a separation point using an excavator or the like.
したがって地中壁の造成の邪魔にならない。Therefore, it does not interfere with the construction of underground walls.
第２図の実施例では、アンカ一体８は鉄筋９によって強
化された波形表面のコンクリート体からなる。In the embodiment of FIG. 2, the anchor body 8 consists of a concrete body with a corrugated surface reinforced by reinforcing bars 9.
アンカ一体８はその上端にねぢ込み口５が固く結合され
、該ねぢ込み口５内に引張部材１がネジ込すれる。A screw hole 5 is firmly connected to the upper end of the anchor unit 8, and the tension member 1 is screwed into the screw hole 5.
第２図の実施例ではアンカ一体８はねぢ込み口５が引張
部材１で引張られるとき、アンカ一体８はねぢ込み口５
を介して引張力を受けろ。In the embodiment shown in FIG.
Receive a tensile force through.
引張部材１は、例えば接着又は溶接によってねぢ込み口
５と結合された１個のシース２で被われている。The tension member 1 is covered with a sheath 2, which is connected to the sink hole 5, for example by gluing or welding.
鉄筋９はそれぞれその両端にかいてオーバーラツプされ
ており、その結果、硬化体４に作用する打撃力による鉄
筋９０オ一バーラツプ部に釦ける破砕が可能である。The reinforcing bars 9 are overlapped at both ends thereof, and as a result, the reinforcing bars 90 can be crushed at the overlap portion by the impact force acting on the hardened body 4.
したがって第１図の場合と同様、埋め殺されたアンカ一
体８０部分に地中壁などの造成される場合、この工事の
邪魔にｉらない。Therefore, as in the case of Fig. 1, if an underground wall or the like is to be constructed in the 80 part of the buried anchor, it will not interfere with the construction work.
本発明の作用効果
アンカ一体３，８が予め定められた破砕点において横方
向から破砕できるようになっているのでアンカ一体３，
８が引張部材１と分離され、地中に埋め殺しの１″＞で
も、この位置で再工事を行うとき、アンカ一体３，８が
容易に破砕される。Effects of the present invention Since the anchor units 3 and 8 can be crushed from the lateral direction at predetermined crushing points, the anchor units 3 and 8 can be crushed from the lateral direction at predetermined crushing points.
Even if the anchor 8 is separated from the tension member 1 and buried in the ground, the anchors 3 and 8 will be easily crushed when re-construction is carried out at this position.
したがってその位置での再工事に支障を来さない。Therefore, there will be no problem with re-construction at that location.
