Description
本発明は、トンネル工事等の岩盤に穿孔された爆破孔に親ダイを装填する際に用いられる親ダイ保持具および親ダイ装填具に関する。 The present invention relates to a parent die holder and a parent die loading tool used when a parent die is loaded into a blast hole drilled in a rock such as tunnel construction.
これまで、発破を行うトンネル工事等の現場では親ダイを穿孔された爆破孔に手作業で込めており、岩石の崩落の危険がある岩盤に近づいて作業を行う必要があった。
近年、作業の安全を確保するため、岩盤から離れた位置より親ダイ及び増し用の爆薬を爆破孔に装填する工法が望まれており、ホースやパイプを使用し岩盤から離れた位置から爆薬を装填する技術が確立されつつある。（たとえば、特許文献１及び特許文献２）
但し、現在の方法では、親ダイはあらかじめ爆破孔内に人手で込める方法が主流であり（たとえば、特許文献３）、パイプに親ダイを挿入して装填する方法もあるが（たとえば、特許文献４及び、非特許文献１）、パイプやホースの先端部の損傷及び磨耗が発生し易く、パイプを度々交換する又はホースの先端を切断加工し損傷部を除去する必要があった。
In recent years, in order to ensure the safety of work, a method of loading the parent die and additional explosive into the blast hole from a position away from the bedrock is desired, and the explosive from a position away from the bedrock using a hose or pipe is desired. Loading technology is being established. (For example, Patent Document 1 and Patent Document 2)
However, in the current method, a method in which the parent die is manually placed in the blast hole in advance is the mainstream (for example, Patent Document 3), and there is also a method in which the parent die is inserted into a pipe and loaded (for example, Patent Document 3). 4 and Non-Patent Document 1), damage and wear of the tip of the pipe or hose are likely to occur, and it was necessary to replace the pipe frequently or to cut the tip of the hose to remove the damaged part.
本発明は、スラリー状の爆薬を機械で遠隔装填する際、岩盤から離れた位置より親ダイを爆破孔に装填するために有用な親ダイ保持具を提供することを目的とする。 An object of the present invention is to provide a parent die holder useful for loading a parent die into a blast hole from a position away from a rock when a slurry-like explosive is remotely loaded by a machine.
本発明者は、前記課題を解決するため鋭意研究を重ねた結果、親ダイの外径以上の内径をもつ円筒形の保持具を用いることを考案し、さらにパイプ又はホースの先端に取り付けることが出来かつ交換可能な形状とすることで課題の解決が可能であることを見出し、本発明をなすに至った。
すなわち、本発明は、下記の通りである。
(1) スラリー状の爆薬を機械装填する際、岩盤に穿孔された爆破孔に親ダイを挿入するために使用する、内径が親ダイの外径以上で、親ダイを保持する部分の長さが親ダイの長さの１／３以上かつ１以下であり、装填パイプ又は装填ホースの先端に着脱可能であることを特徴とする樹脂製円筒形の親ダイ保持具。
(2) スラリー状の爆薬を機械装填する際、（１）記載の親ダイ保持具の内径以下の外径を持ったパイプ先端に、前記(1)記載の親ダイ保持具を装着した親ダイ装填具。
(3) スラリー状の爆薬を機械装填する際、（１）記載の親ダイ保持具の内径以下の外径を持ったホースの先端に、前記(1)記載の親ダイ保持具を装着した親ダイ装填具。
に関する。
As a result of intensive studies to solve the above problems, the present inventor has devised using a cylindrical holder having an inner diameter equal to or larger than the outer diameter of the parent die, and can be attached to the tip of a pipe or hose. It has been found that the problem can be solved by making the shape exchangeable and replaceable, and the present invention has been made.
That is, the present invention is as follows.
(1) The length of the part that holds the parent die that has an inner diameter that is larger than the outer diameter of the parent die and is used to insert the parent die into the blast hole drilled in the rock when loading the slurry-like explosive A resin cylindrical parent die holder characterized in that is 1/3 or more and 1 or less of the length of the parent die and is detachable from the tip of the loading pipe or loading hose.
(2) When a slurry-like explosive is mechanically loaded, a parent die in which the parent die holder described in (1) above is attached to the end of a pipe having an outer diameter equal to or smaller than the inner diameter of the parent die holder described in (1) Loading tool.
(3) When the slurry-like explosive is mechanically loaded, the parent die holder described in (1) above is attached to the tip of a hose having an outer diameter equal to or less than the inner diameter of the parent die holder described in (1). Die loading tool.
About.
本発明品を使用することにより、確実に親ダイを保持することが可能であり、パイプ又はホースの先端の磨耗を防止でき岩盤から離れた位置から親ダイを爆破孔に挿入することが可能になった。 By using the product of the present invention, it is possible to securely hold the parent die, prevent wear of the tip of the pipe or hose, and insert the parent die into the blast hole from a position away from the rock. became.
以下、本発明について具体的に説明する。
親ダイとは雷管付き起爆爆薬のことであり、本発明で使用される親ダイの爆薬の種類としては膠質ダイナマイト及び含水爆薬が適し、爆薬の寸法としては外径２５〜３０ｍｍ、長さ１００〜３００ｍｍが適し、使用される雷管の種類は電気式雷管、非電気式雷管を問わない。
保持具の長さは親ダイ挿入部とパイプ接合部の合計の長さで決まるが、親ダイ挿入部の長さは、親ダイに使われる爆薬の１／３以上かつ１以下の長さが必要であり、１／３以下になると保持が不安定になり、１以上にすると親ダイを付け間違ったときに取り外すのが難しくなる。
Hereinafter, the present invention will be specifically described.
The parent die is an explosion explosive with a detonator. As the type of explosive for the parent die used in the present invention, colloidal dynamite and hydrous explosive are suitable, and the explosive dimensions are an outer diameter of 25 to 30 mm and a length of 100 to 300 mm is suitable, and the type of detonator used may be an electric detonator or a non-electric detonator.
The length of the holder is determined by the total length of the parent die insertion part and the pipe joint part, but the length of the parent die insertion part is not less than 1/3 and not more than 1 of the explosive used in the parent die. It is necessary, and when it becomes 1/3 or less, the holding becomes unstable, and when it becomes 1 or more, it becomes difficult to remove it when the parent die is attached incorrectly.
パイプ接合部の長さは、パイプの長さ以下である必要があり、交換の簡便さを優先するなら２０〜１００ｍｍの長さが好ましく、パイプの保護を優先するのであれば穿孔された爆破孔と同じ長さで、爆破孔に挿入された長さのパイプ外面を保持具で覆うことも可能である。
保持具の内径は使用する親ダイの外径以上が必須であり、親ダイ外径より１〜５ｍｍ大きいものであることが望ましい。
穿孔する爆破孔の孔径は、保持具の外径以上であることが必要である。保持具の外径は、通常、保持具の内径より１〜５ｍｍ大きいものが軽くて使い易く好ましい。
保持具の材質は、円筒状に加工可能なプラスチックが適しており、より好ましくはポリオレフィン系の材質が安価で加工性が良く使いやすい。
The length of the pipe joint needs to be equal to or less than the length of the pipe. If priority is given to easy replacement, a length of 20 to 100 mm is preferable. If priority is given to protection of the pipe, a perforated blast hole It is also possible to cover the outer surface of the pipe of the same length as that inserted into the blast hole with a holder.
The inner diameter of the holder must be greater than or equal to the outer diameter of the parent die to be used, and is desirably 1 to 5 mm larger than the outer diameter of the parent die.
The hole diameter of the blast hole to be drilled needs to be larger than the outer diameter of the holder. In general, the outer diameter of the holder is preferably 1 to 5 mm larger than the inner diameter of the holder and is light and easy to use.
As the material of the holder, a plastic that can be processed into a cylindrical shape is suitable, and more preferably, a polyolefin-based material is inexpensive, easy to use and easy to use.
親ダイ装填具に使用するパイプ又はホースは、親ダイ保持具の内径以下の外径を持ち長さは機械装填機の能力及び希望する遠隔装填距離により決まる。本発明の親ダイ装填具を使用することにより、親ダイを親ダイ保持具に保持したまま爆破孔の奥まで運ぶことが出来、続いてスラリー薬をパイプ又はホースから押出すことによって、親ダイが親ダイ保持具から押出され、爆破孔の奥にセットすることが出来る。
親ダイ保持具をパイプ又はホースに接続する方法としては、粘着テープで固定あるいは接着する方法を取ることが出来るが、粘着テープを用いるほうが交換の際簡単に済むのでより好ましい。
The pipe or hose used for the parent die loader has an outer diameter that is less than or equal to the inner diameter of the parent die holder and the length depends on the capacity of the machine loader and the desired remote loading distance. By using the parent die loading tool of the present invention, the parent die can be transported to the depth of the blast hole while being held by the parent die holder, and then the slurry die is extruded from the pipe or hose, Can be extruded from the parent die holder and set in the back of the blast hole.
As a method of connecting the parent die holder to the pipe or hose, a method of fixing or adhering with an adhesive tape can be used. However, it is more preferable to use an adhesive tape because it can be easily replaced.

A hydrous explosive parent die having an explosive diameter of 25 mm and a length of 180 mm is attached as shown in FIG. 1 to the parent die loading tool of the present invention attached using Was loaded about 1000 times to confirm the retention of the parent die and damage to the pipe tip, and good results were obtained.
［比較例１］
親ダイ保持具を装着していない実施例１に用いたものと同じＣＦＲＰ製パイプの先端を図２のように加工し、実施例１及び２と同じ親ダイを保持させて岩盤から約１．５ｍ離れた位置から爆破孔に装填した結果、１０回に１回程度親ダイが装填途中で外れる現象が起き、約１００回装填した後に加工部分が折れてパイプを交換しなければならなかった。
[Comparative Example 1]
The tip of the same CFRP pipe used in Example 1 without the parent die holder attached is processed as shown in FIG. 2, and the same parent die as that in Examples 1 and 2 is held, and about 1. As a result of loading into the blast hole from a position 5 m away, a phenomenon that the parent die was detached during loading about once every 10 times occurred, and after about 100 times loading, the processed part was broken and the pipe had to be replaced.
