。このため次のような種々の欠点があった。(Conventional technology) In the conventional ground anchor construction method, a concrete pedestal, etc. that has been pre-formed into a predetermined shape is transported and installed to the exposed part of the ground anchor tension member, and the tension member is attached to the pedestal with a bearing plate and an anchor. The method used was to fix it through For this reason, there were various drawbacks as follows.
（イ）成型したコンクリート製台座等は重量が非常に重
いので運搬・設置には強力なりレーン等を必要とし、手
間と時間を要するのみでなく危険性が高かった。(a) Molded concrete pedestals are very heavy and require strong lanes to transport and install, which not only requires time and effort but is also highly dangerous.

がきわめて悪かった。(b) Since a pre-molded product was used, workability on site was extremely poor.
（・・）台座を設置する地表面と同台座の底面との密着
状態が密着不良を生じることが多かった。(...) Poor adhesion often occurred between the ground surface on which the pedestal was installed and the bottom surface of the pedestal.
（ニ）予め成型した台座を設置して固定するので、設置
固定不備による偏在的な不等分布荷重となり、台座の破
壊もしくは支持地盤の破壊を生ずるおそれがあった。(d) Since a pre-molded pedestal is installed and fixed, there is a risk that the pedestal or the supporting ground will be destroyed due to unevenly distributed loads due to improper installation and fixing.

法にある。(Means for Solving the Problems) The gist of the present invention that solves the problems is that the exposed part of the ground anchor tension member whose end part is fixed in the ground is flexible and partially or entirely A formwork with a predetermined shape containing a water-permeable bag and open at least on the ground surface side is installed, and then a hardening material such as cement milk is press-fitted into the bag until a predetermined internal pressure is reached, and then hardened. This method of constructing a ground anchor pedestal is characterized in that a pedestal is formed on-site by hardening the material, and a ground anchor tension member is fixed to the pedestal.
（作用）
本発明のグランドアンカー台座゛施工法においては、少

取付けた型枠を使用する方法、又は少なくとも地表面側
を開放した型枠に同シート材で製作した袋体を内蔵させ
たものを使用する方法等がある。(Function) In the ground anchor pedestal construction method of the present invention, a method using a formwork with a flexible and water-permeable sheet material attached at least on the ground surface side, or a formwork with at least the ground surface side open Another method is to use a bag made of the same sheet material with a built-in bag.
まず袋体な内蔵させた型枠を使用する方法について述べ
る。First, we will discuss the method of using a formwork with a built-in bag.
グランドアンカー引張部材の地表露出部に、袋体を内蔵
した型枠を設置する。次に同袋体内に外部より硬化材を
圧入するが、同袋体は可撓性を有しているので硬化材の
圧入とともに膨張し、同型枠の内部形状に沿った形状と
なる。また同袋体の一部又は全部は透水性を有している
ので同袋体内の硬化材の内圧により同硬化材中の水分は
同袋体を透過して外部へ浸出するようになっている。A formwork with a built-in bag is installed on the exposed surface of the ground anchor tension member. Next, a hardening material is press-fitted into the bag from the outside, but since the bag is flexible, it expands as the hardening material is press-fitted, and takes on a shape that follows the internal shape of the mold. In addition, since part or all of the bag has water permeability, the internal pressure of the hardening material inside the bag causes the water in the hardening material to permeate through the bag and leak out to the outside. .
従って同袋体への硬化材の注入圧力を調節するこ＝ ４
とにより同袋体の内圧を調整し、浸出する水分量をコン
トロールすることにより、同袋体内の硬化材中の水分含
有量を適切な値にすることができる。すなわち硬化材中
の水分含有量を最初は圧入時の搬送性を良くするような
値にしておき、同袋体内に圧入した後は硬化性を良くす
るような値に再調整することができるよ・うになってい
る。Therefore, by adjusting the injection pressure of the hardening material into the bag, the internal pressure of the bag can be adjusted, and by controlling the amount of water leached out, the water content in the hardening material inside the bag can be controlled. You can set it to an appropriate value. In other words, the moisture content in the hardening material can be initially set to a value that improves transportability during press-fitting, and then readjusted to a value that improves hardenability after being press-fitted into the same bag.・The sea urchin is turning.
同袋体を内蔵した型枠は、少なくとも地表面側を開放し
ているので、同袋体の一部は同地表面と接することにな
る。同袋体は可撓性を有しているので、硬化材圧入で膨
張させると同地表面の凹凸に沿った形状となり密着性は
良好である。また同袋体の同地表面と接する部分が透水
性を有していれば、硬化材の圧入により、硬化材成分を
含んだ水分が同袋体を透過して同地表面の内部へ浸透す
るので、硬化後は同硬化材の入った同袋体と同地表面と
の密着力は強力なものとなる。Since the formwork containing the bag body is open at least on the ground surface side, a portion of the bag body comes into contact with the ground surface. Since the bag is flexible, when it is inflated by press-fitting a hardening material, the bag conforms to the unevenness of the ground surface and has good adhesion. In addition, if the part of the bag in contact with the ground surface has water permeability, by press-fitting the hardening material, water containing the hardening material will pass through the bag and penetrate into the inside of the ground surface. Therefore, after curing, the bag containing the hardening material has a strong adhesion to the ground surface.
同袋体内へ硬化材を所定内圧になるまで圧入し、同硬化
材が硬化したら、外側の型枠を除去して、硬化した成型
体に前出のグランドアンカー引張部材を取付けて台座と
する。なお型枠を除去せずそのまま台座とすることもで
きる。A hardening material is press-fitted into the bag until a predetermined internal pressure is reached, and once the hardening material has hardened, the outer formwork is removed and the above-mentioned ground anchor tension member is attached to the hardened molded body to form a pedestal. It is also possible to use it as a pedestal without removing the formwork.
本発明では、型枠の開放面を地表面側のみでなく側面等

体化させて成型することかできるようにしたものである
。また硬化材圧入により浸出した水分の排水性を良くし
たものでもある。In the present invention, the open surface of the formwork is not only the ground surface side, but also other surfaces such as the side surfaces are also open surfaces. This allows the pedestals to be integrally molded when they are installed adjacent to each other. It also improves drainage of moisture leached out by press-fitting the hardening material.

た型枠を使用すること等も可能である。In the present invention, there is also a method of using a formwork to which a sheet material having flexibility and water permeability is attached at least on the ground surface side. The inside of the formwork is a space formed by the walls of the formwork and the same sheet material, so a hardening material such as cement milk is press-fitted into the space to expand the sheet material toward the ground surface. It is designed to be in close contact with each other. Since the material is flexible and water-permeable, it can achieve strong contact with the ground surface in the same manner as the bag described above. In addition, in the same formwork, since it is sufficient to attach the same sheet material to at least the ground surface side, it is also possible to use a formwork in which the same sheet material is attached to the side part.
