方法として未だ不充分であった。Therefore, recently, steel materials have been coated with smooth material (rl).
(Refer to Japanese Unexamined Patent Publication No. I'1!55-147594), spraying urethane foam, etc. onto steel materials during processing and pressing them into soil concrete (Japanese Patent Publication No.
2-113004), they tried to make steel drawing easier, but in the case of the former, the i11 slip material was not sufficient for drawing steel, and in the case of the former, the preliminary blowing caused uneven processing. This method was still unsatisfactory as a method for drawing steel materials, as it tended to result in insufficient peeling.

It is a flexible cylindrical body, and the steel material (1) is inserted into the cylindrical body (2) with a sufficient gap. In the case of the figure, the cylindrical body (2) is made of 1-1 steel and is made of a square tube through which the steel material (1) can be inserted. duct tape (

引抜きが実現できる。As described above, this invention facilitates the elasticity of steel materials for columnar earth retaining, and the steel materials are preliminarily made of elastic material made of a flexible foamed resin sheet laminated with a non-foamed resin film or sheet on at least the inner surface. Because of the construction method, the soil concrete is inserted into a rich cylindrical body and covered with a bottom cover, and then pushed into the soil concrete that has been installed at the perforation point in the ground, so the soil concrete 1 cannot be penetrated into the cylindrical body. Furthermore, even if the soil concrete is suppressed, the elasticity of the cylindrical body will cause it to act as an elastic intermediate between the steel and the soil concrete. When pulling out the steel material, it is very easy to pull out due to the appropriate substantial gap created by the interposition of the cylindrical body, and smooth pulling can be achieved without being affected by the pile caused by the Soil Funkuri-1.
しかも筒状体は施工中鋼材の保護をはかる上でも非常に
役立つもので、鋼材の再使用をはかる上で好都合となる
。Furthermore, the cylindrical body is extremely useful in protecting the steel material during construction, and is convenient for reusing the steel material.
