【発明の詳細な説明】
（産業上の利用分野）
本発明は、隠退掘削岩盤の内壁に対する一次吹付コンク
リート工法の改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an improvement in the primary shotcrete construction method for the inner wall of a retreat excavated rock mass.
（従来の技術）
従来行われている隧道掘削岩盤の内壁に対する一次吹付
コンクリートは、所定の形状１寸法に仕上げるには極め
て手数がかかり、非能率的な施工の現状である。(Prior Art) The conventional method of primary shotcrete for the inner walls of tunnel excavated rock is extremely time consuming and inefficient to finish in a predetermined shape and dimension.
（発明が解決しようとする課題）
この現状に対し、コンクリートを吹付する際所定の形状
２寸法を設定し易くするため、埋設用支保工構造体を設
けることにより、非能率的な施工の現状を改良しようと
するものである。(Problem to be solved by the invention) To address this current situation, in order to make it easier to set two predetermined shapes and dimensions when spraying concrete, a support structure for burial is provided, thereby solving the current inefficient construction process. It is an attempt to improve.
（課題を解決するための手段）
次に実施例を示す図面によって、その構成について説明
する。(Means for Solving the Problems) Next, the configuration of the embodiment will be explained with reference to drawings showing the embodiment.
（イ）、隠退掘削した岩盤（６）の内壁に対し一次吹付
コンクリート（５）の仕上り内壁面に合わせて形成した
支保工（１）を、所定の間隔を設けて吹付前に離道状に
配列し、
（ロ）、かつ、多数の継ぎ材（２）によって例えばさや
管（３）等を利用し、それぞれ組み合わせてなる支保工
構造体（４）を基準として、支保工構造体（４）を埋設
するように一次吹付コンクリートを形成する。(b) Shoring (1) formed to match the finished inner wall surface of the primary shotcrete (5) on the inner wall of the bedrock (6) that has been retreated and excavated is placed at a predetermined interval in the form of an escape road before spraying. A shoring structure (4) is constructed based on the shoring structure (4) which is arranged and combined using (b) and a large number of splicing materials (2), for example, sheath pipes (3), etc. Form the primary shotcrete to bury the concrete.
（作用）
本発明は以上のような構成であるから、支保工構造体（
４）の薄肉管（１）および継ぎ材（２）を基準として、
これを埋め込むように一次吹付コンクリートの内壁を形
成できる。(Function) Since the present invention has the above configuration, the shoring structure (
Based on the thin-walled pipe (1) and joint material (2) in 4),
The inner wall of primary shotcrete can be formed to embed this.
（実施例）
本発明の素材とその形状、サイズおよび支保工構造体の
組み合わせ方は各種に適用できるもので、例えば支保工
（１）は薄肉管に限定する必要はなく、外側の表面積を
拡大するような形状は、一次吹付コンクリートとの接着
強度を増大できるような工法に役立つものである。(Example) The combination of the material of the present invention, its shape, size, and shoring structure can be applied to various types. For example, the shoring (1) does not need to be limited to a thin-walled pipe, and the outer surface area can be expanded. This shape is useful for construction methods that can increase the adhesive strength with primary shotcrete.
（発明の効果）
従来使用されていなかった本発明の支保工構造体（４）
に則り、一次吹付コンクリートを施工できるから、工事
は正確で極めて能率的で、かつ、強度的にも安全性を確
保できる。(Effect of the invention) Shoring structure of the present invention that has not been used conventionally (4)
Because primary shotcrete can be constructed in accordance with the above, construction work is accurate and extremely efficient, and it also ensures safety in terms of strength.
