Abstract

PROBLEM TO BE SOLVED: To provide an innovative explosion pressure guide control device with which during blasting work of an outermost perimeter hole in a tunnel, and a road surfaces, wall surfaces, and the like at locations where adjacent buildings are positioned in a city center, explosive pressure is restrictively transmitted only to a blasting area without exceeding a blasting presumptive line, a smooth and fine blasting surface is secured, excessive excavation is prevented, and tremors and vibration are minimized, and thus, an effect of increasing blasting efficiency is provided while blasting cost is greatly reduced by simply using a general low-cost explosive.SOLUTION: Only one side of an explosive 1 is partially wrapped along its longitudinal direction and the explosive is loaded in an explosion pressure shutoff cover 110, and then the explosion shutoff cover is inserted into a blasthole 2 so that it is directed toward the blasting presumptive line 4, so that a transmission path of explosion pressure can be freely controlled allowing the explosion pressure to be transmitted only to the blasting area in an other side direction of the blasting presumptive line, while the explosion pressure is transmitted in the blasting presumptive line direction, by the explosion shutoff cover during the blasting work.

Description

本発明はトンネルの最外郭孔や都心の近接構造物が位置した場所の道路面、壁面などの発破作業の時、爆圧誘導制御装置を利用して爆圧が発破予定線を超えないで、発破領域のみに制限的に伝達されるように爆圧の伝達経路を制御して、さらに滑らかで美麗な発破面を確保し、過大掘りを防止し、且つ震動と騷音を最小化する革新的な発破技術に関する。   In the present invention, when blasting work on the road surface, wall surface, etc., where the outermost hole of the tunnel and the adjacent structure in the city are located, the explosion pressure does not exceed the expected blast line using the explosion pressure induction control device, Innovative that controls the transmission path of the explosion pressure so that it is transmitted only to the blasting area, ensuring a smooth and beautiful blasting surface, preventing excessive digging, and minimizing vibration and noise Related to blasting technology.

一般に、建設及び土木工事は国家の基幹産業で、産業が発達するにつれて、工事の規模や回数が増加し、このような建設及び土木工事を行うための基礎工事として発破作業は各種工事現場（道路建設、トンネル、都心の近接構造物が位置した場所など）で最も頻繁に行われる作業の一つである。   In general, construction and civil engineering work are national key industries, and as the industry develops, the scale and frequency of construction increases, and blasting work is carried out at various construction sites (roads) as foundation work for such construction and civil engineering work. One of the most frequent operations in construction, tunnels, and places where nearby structures in the city are located.

前記発破作業は岩盤を取り除くための作業で、これを最も簡単に取り除くことができる方法としては普遍的に爆薬を利用し、前記爆薬は購入が容易で、且つ運用が便利な長所がある。   The blasting work is a work for removing the bedrock, and the most easy way to remove it is to use explosives universally, and the explosives have the advantage of being easy to purchase and convenient to operate.

周知のように、一般的な発破工法は、円形の発破孔を穿孔して中央に爆薬を装填して発破する方式で、発破孔の孔壁全体に均一な爆圧を加えることで、特に、トンネルの施工の時、トンネル断面が滑らかでなく凸凹で、発破震動及び騷音が強くて、爆圧がトンネルの発破予定線を越えてさらに掘削されながら過大掘りが発生される問題点がある。   As is well known, a general blasting method is a method in which a circular blast hole is drilled and blasted by loading an explosive in the center, and by applying a uniform blast pressure to the entire wall of the blast hole, When constructing a tunnel, there is a problem that the tunnel cross section is not smooth and uneven, the blasting vibration and noise are strong, and the explosive pressure exceeds the expected blasting line of the tunnel and further overexcavation occurs.

従って、このような問題点を解消するためには爆圧を制御することが非常に重要で、現在までこのような爆圧を制御する方法として、自由面の位置と孔間隔を適切に調節する方法、デカップリング装薬方法などが提案されているが、これらは費用が高く、制御効果があまり大きくないという短所がある実情である。   Therefore, it is very important to control the explosion pressure in order to solve such problems. Until now, as a method for controlling such an explosion pressure, the position of the free surface and the hole interval are appropriately adjusted. A method, a decoupling charging method, and the like have been proposed, but these are disadvantageous in that they are expensive and the control effect is not so great.

特に、前記デカップリング装薬方法は最も普遍的に多く使っている精密爆薬を利用した発破方法で、発破孔の中央に設置された爆薬と前記発破孔の孔壁との間に空気層を形成することによって、前記発破孔の孔壁全体に均一に作用する爆薬の衝撃効果が全体的に減少しながら、破壊範囲が減少される現象を利用して発破予定線に沿って割れ目が発生するようにしている。   In particular, the decoupling charge method is a blasting method using the most widely used precision explosive, and an air layer is formed between the explosive installed in the center of the blasting hole and the hole wall of the blasting hole. By doing so, the impact effect of the explosive that uniformly acts on the entire hole wall of the blast hole is reduced as a whole, and a crack is generated along the expected blast line using the phenomenon that the fracture range is reduced. I have to.

しかし、この場合爆薬の全体的な衝撃効果が減少されるにつれて、前記発破予定線の内側方向（発破領域）にはむしろ爆圧が不足して、過小掘りが発生する問題点があり、既存の発破方法に比べて、過大掘りの発生領域が若干減る程度の微細な効果を提供することに過ぎない実情である。   However, in this case, as the overall impact effect of the explosives is reduced, there is a problem that the explosive pressure is rather insufficient in the inner direction (blasting area) of the blasting line, resulting in the occurrence of undermining. Compared to the blasting method, it is only a matter of providing a fine effect to the extent that the over-digging area is slightly reduced.

本発明は従来の技術による発破工法が内包している諸問題点を積極的に解消するためのもので、爆薬の長手方向に沿って一方のみを部分的に包んで爆圧遮断カバーに爆薬を装填した後、前記爆圧遮断カバーが発破予定線を向けるように発破孔に挿入して、発破作業の時、前記爆圧遮断カバーによって、発破予定線方向には爆圧が伝達されないながらも、前記発破予定線の他側方向である発破領域のみに爆圧が伝達されるように爆圧の伝達経路を自由に制御することができる爆圧誘導制御装置を提供することを発明の解決課題とする。   The present invention is intended to actively solve the problems inherent in the blasting method according to the prior art, and partially wraps only one of the explosives along the longitudinal direction of the explosive and covers the explosive pressure blocking cover with the explosive. After loading, the explosive pressure blocking cover is inserted into the blasting hole so that the blasting planned line is directed, and at the time of blasting work, the explosive pressure is not transmitted in the blasting planned line direction by the explosive pressure blocking cover, An object of the present invention is to provide an explosion pressure induction control device capable of freely controlling a transmission path of an explosion pressure so that the explosion pressure is transmitted only to a blasting region that is on the other side of the blasting line. To do.

本発明は前記課題を解決するための手段で、円形断面状を有する爆圧遮断カバーの一側に部分的に開放された爆圧誘導路を形成し、前記爆圧誘導路の内側には爆薬装填部を形成し、前記爆圧遮断カバーの内面に二重壁及び三重壁を連続的に一体に形成する一方、前記二重壁は長手方向の一側に外側へ突出された結合突起を形成し、他側には結合溝を形成させたカバー組立手段を備えることによって、前記爆圧遮断カバーを爆薬の数に合わせて組み立てて連結して用いることができる爆圧誘導制御装置の技術を提供する。   The present invention is a means for solving the above-mentioned problems, and an explosive pressure guide path that is partially opened is formed on one side of an explosive pressure blocking cover having a circular cross-sectional shape, and an explosive is disposed inside the explosive pressure guide path. A loading part is formed, and a double wall and a triple wall are continuously and integrally formed on the inner surface of the explosion pressure blocking cover, while the double wall forms a coupling protrusion protruding outward on one side in the longitudinal direction. In addition, by providing a cover assembly means having a coupling groove formed on the other side, a technique for an explosive pressure induction control device that can be used by assembling and connecting the explosive pressure blocking cover according to the number of explosives is provided. To do.

本発明によれば、爆薬の一方のみを部分的に包む爆圧遮断カバーが発破予定線を向けるように発破孔に配置されることによって、発破作業の時、前記爆圧遮断カバーは爆圧が発破予定線に伝達されることを遮断し、爆圧は前記発破予定線を超えないで前記発破予定線の内側方向である発破領域のみに制限的に伝達することで、前記発破予定線に沿って発破面が正確に形成され、前記発破面はより滑らかで美麗になるとともに、過大掘りを効果的に防止しながらも、震動と騷音を最小化して工事品質を画期的に向上させる効果を奏する。   According to the present invention, the explosive pressure blocking cover that partially wraps only one of the explosives is disposed in the blasting hole so that the blasting line is directed, so that the explosive pressure blocking cover has an explosive pressure during the blasting operation. By blocking the transmission to the blasting planned line, the explosion pressure does not exceed the blasting planned line and is limitedly transmitted only to the blasting area which is the inner side of the blasting planned line. The blasting surface is accurately formed, making the blasting surface smoother and more beautiful, while effectively preventing excessive digging, while minimizing vibration and noise, improving the construction quality dramatically Play.

また、一般の廉価の爆薬を前記爆圧遮断カバーに装填して簡便に使用することによって、既存に使っていた高価の精密爆薬を取り替えることができて、発破費用を大幅に節減しながらも発破効率は増大されて、経済的な波及効果が非常に大きい有用な効果を奏する。   In addition, it is possible to replace existing high-priced explosives by simply loading a general low-priced explosive into the explosive pressure-blocking cover, and blasting while greatly reducing blasting costs. The efficiency is increased, and a useful effect having a very large economic ripple effect is obtained.

以下、前記概略的な段階からなる本発明を容易に実施するようにそれぞれの段階別に詳しく説明する。   Hereinafter, each step will be described in detail so as to easily implement the present invention including the above-described general steps.

（１）爆薬装填段階（Ｓ１０）
まず、本発明は長手方向に沿って一側に爆圧誘導路１１１が形成された複数の爆圧遮断カバー１１０にそれぞれ爆薬１を装填する。 (1) Explosive loading stage (S10)
First, in the present invention, each of the explosives 1 is loaded into a plurality of explosive pressure blocking covers 110 in which explosive pressure guide paths 111 are formed on one side along the longitudinal direction.

即ち、前記爆薬１を、図５のように、爆圧遮断カバー１１０の内側に形成された爆薬装填部１１２に押し入れながら装填した後、連結バンド１１５で前記爆薬１を包みながら流動が発生しないように堅固に固定する。   That is, as shown in FIG. 5, the explosive 1 is loaded while being pushed into an explosive loading portion 112 formed on the inner side of the explosive pressure blocking cover 110, so that no flow occurs while wrapping the explosive 1 with a connecting band 115. Securely fix to.

この時、前記爆圧遮断カバー１１０は、一側に爆圧誘導路１１１が開放して形成されることによって、前記爆圧誘導路１１１を基点に、図５のように、両端部が図面において上下に自由に流動することができるテンションを確保し、それによって、爆薬１の大きさや形態及び種類に関係なく、多様な爆薬１をさらに順調に装填することができるという効果を奏する。   At this time, the explosive pressure blocking cover 110 is formed by opening the explosive pressure guiding path 111 on one side, so that both ends of the explosive pressure blocking cover 110 are illustrated in FIG. The tension which can flow freely up and down is ensured, and thereby there is an effect that various explosives 1 can be loaded more smoothly regardless of the size, form and type of the explosive 1.

また、前記爆圧遮断カバー１１０は、爆薬１と同じ長さに形成されることによって、一つの爆圧遮断カバー１１０には一つの爆薬１を装填することができ、前記爆薬１の使用量に合わせて対応する数だけ爆圧遮断カバー１１０を使用すれば良い。   In addition, the explosive pressure blocking cover 110 is formed to have the same length as the explosive 1, so that one explosive blocking cover 110 can be loaded with one explosive 1. It is only necessary to use a corresponding number of explosive pressure blocking covers 110.

（２）カバーの組み立て段階（Ｓ２０）
前記爆薬１が１：１の割合で装填された複数の爆圧遮断カバー１１０は、相互一体性を維持することができるように、前記爆圧遮断カバー１１０の長手方向の一側に形成された結合突起１４１を、図７のように、他の爆圧遮断カバー１１０に形成された結合溝１４２に挿入する方法で前記爆薬１が装填された爆圧遮断カバー１１０を連続的に一体化に連結することができる。 (2) Cover assembly stage (S20)
The plurality of explosive pressure blocking covers 110 loaded with the explosive 1 at a ratio of 1: 1 are formed on one side in the longitudinal direction of the explosive pressure blocking cover 110 so as to maintain mutual integrity. As shown in FIG. 7, the explosive pressure blocking cover 110 loaded with the explosive 1 is continuously and integrally connected by inserting the connecting protrusion 141 into a connecting groove 142 formed in another explosive pressure blocking cover 110 as shown in FIG. can do.

従って、前記爆圧遮断カバー１１０は相互一体性を維持するとともに、爆薬１の場合にも長手方向に一体に連結された状態を維持することによって、何れか一つの爆薬１に***を連結して発破しても爆薬１が全体的に一緒に***されることができる。   Accordingly, the explosive pressure blocking cover 110 maintains mutual integrity, and also in the case of the explosive 1, the detonator is connected to any one of the explosives 1 by maintaining the state of being integrally connected in the longitudinal direction. The explosive 1 can be blown together as a whole even if it is blasted.

（３）カバー設置段階（Ｓ３０）
前記爆圧遮断カバー１１０の連結組み立てが完了されると、何れか一つの爆薬１と連結された***脚線５を発破孔２の外部に露出させた状態で、前記連結して組み立てられた複数の爆圧遮断カバー１１０を発破孔２に挿入する。 (3) Cover installation stage (S30)
When the assembly of the explosive pressure blocking cover 110 is completed, the detonator leg 5 connected to one of the explosives 1 is exposed to the outside of the blast hole 2 and assembled. A plurality of explosion pressure blocking covers 110 are inserted into the blast holes 2.

この時、特に、図１のように、トンネル３の発破作業の時、爆圧が発破予定線４を超えないで前記発破予定線４の内側のみに制限的に伝達されるように制御するためには、必ず前記爆圧遮断カバー１１０が発破予定線４を向けるように発破孔２に挿入されなければならない。   At this time, in particular, as shown in FIG. 1, in the blasting operation of the tunnel 3, in order to control the explosion pressure so as to be limitedly transmitted only to the inside of the blasting planned line 4 without exceeding the blasting planned line 4. In this case, the explosion pressure blocking cover 110 must be inserted into the blast hole 2 so that the blasting line 4 is directed.

即ち、前記爆圧遮断カバー１１０は、図６のように、発破予定線４を向けるように配置した時、前記爆圧遮断カバー１１０を挟んで発破予定線４と爆薬１とは相互隔離された状態を維持し、それによって、発破作業の時、前記爆圧遮断カバー１１０は爆圧が発破予定線４を超えないように防止して、正確に発破予定線４に沿ってさらに滑らかで、美麗な発破面を形成し、過大掘りの発生を効率的に防止するとともに、震動と騷音を減少することができる。   That is, when the explosive pressure blocking cover 110 is arranged so that the expected blast line 4 faces as shown in FIG. 6, the blasting planned line 4 and the explosive 1 are separated from each other with the explosive pressure blocking cover 110 interposed therebetween. The state is maintained, so that, during the blasting operation, the explosive pressure blocking cover 110 prevents the explosive pressure from exceeding the planned blast line 4, and is more accurately and smoothly along the planned blast line 4. A blast surface can be formed to prevent over-digging efficiently and reduce vibration and noise.

また、爆圧は前記爆圧遮断カバー１１０に形成された爆圧誘導路１１１を通じて所望の発破領域に順調に集中誘導されることによって過大掘りが発生しない効果を奏する。   Further, the explosion pressure is smoothly concentrated and guided to a desired blasting region through the explosion pressure guiding path 111 formed in the explosion pressure blocking cover 110, so that an excessive digging does not occur.

同時に、前記爆圧遮断カバー１１０の外周面に形成された緩衝突起１１３は、発破の時、発破孔２の孔壁にぶつかる時緩衝作用をすることによって、爆圧が発破予定線４に伝達されることをさらに効率的に遮断する。   At the same time, the buffer protrusion 113 formed on the outer peripheral surface of the explosion pressure blocking cover 110 acts as a buffer when it collides with the hole wall of the blast hole 2 at the time of blasting, so that the blast pressure is transmitted to the expected blast line 4. To block things more efficiently.

一方、前記***脚線５の前端に連結される通常の***は、前記連結して組み立てられた複数の爆圧遮断カバー１１０の真中に位置する爆圧遮断カバー１１０に装填された爆薬１と一体に連結した状態で、前記***脚線５を爆圧遮断カバー１１０の内面と爆薬１との間に発生する隙間６に沿って外部に長く露出されるようにすることによって、爆圧遮断カバー１１０の設置作業の時、前記***脚線５を発破孔２の外部に便利に露出させることができる。   On the other hand, a normal detonator connected to the front end of the detonator leg 5 is composed of the explosive 1 loaded in the explosion blocking cover 110 located in the middle of the plurality of explosion blocking covers 110 assembled together. In a state of being integrally connected, the detonator leg 5 is exposed to the outside along the gap 6 generated between the inner surface of the explosive pressure blocking cover 110 and the explosive 1, thereby blocking the explosive pressure. When the cover 110 is installed, the detonator leg 5 can be conveniently exposed outside the blast hole 2.

（４）填塞物充填段階（Ｓ４０）
前記爆薬１が装填された爆圧遮断カバー１１０の設置が完了された後には、爆薬１が密閉効果によって十分な威力を発揮し、同時に騷音及び飛散を防止することができるように、前記発破孔２に砂や粘土などの填塞物７を充填する。 (4) Filling material filling stage (S40)
After the installation of the explosive pressure blocking cover 110 loaded with the explosive 1 is completed, the explosive 1 is sufficiently powerful due to the sealing effect, and at the same time, the blasting can be prevented. The hole 2 is filled with a filler 7 such as sand or clay.

（５）***脚線結束及び発破段階（Ｓ５０）
前記填塞物７の充填が完了されると、発破孔２で外部に露出された***脚線５を発破母線と電気的に一体化に連結する。 (5) Detonator leg wire uniting and blasting stage (S50)
When the filling of the filling material 7 is completed, the detonator leg 5 exposed to the outside through the blasting hole 2 is electrically connected to the blasting busbar in an integrated manner.

また、前記発破母線と連結された発破操作機を利用して遠く離れた場所で***に電気を供給して爆薬１を発破する。   In addition, the explosive 1 is blasted by supplying electricity to the detonator at a remote location using a blasting operation device connected to the blasting bus.

一方、以下では本発明の発破工法に適用される爆圧誘導制御装置１００の技術構成に対して説明する。   On the other hand, hereinafter, a technical configuration of the explosion pressure induction control device 100 applied to the blasting method of the present invention will be described.

まず、本発明の爆圧誘導制御装置１００は、図３〜図７のように、一側に形成された爆圧誘導路１１１の内側に爆薬装填部１１２が形成された複数の爆圧遮断カバー１１０と；前記爆圧遮断カバー１１０の内側に連続的に曲面状に一体化に形成される二重壁１２０及び三重壁１３０と；前記複数の爆圧遮断カバー１１０を長手方向に一体化に連結して組み立てることができるようにするカバー組立手段１４０との有機的な結合構成からなる。   First, as shown in FIGS. 3 to 7, the explosive pressure guidance control device 100 of the present invention includes a plurality of explosive pressure blocking covers in which an explosive loading section 112 is formed inside an explosive pressure guide path 111 formed on one side. 110; a double wall 120 and a triple wall 130 which are integrally formed in a curved shape continuously inside the explosion pressure blocking cover 110; and a plurality of the explosion pressure blocking covers 110 are integrally connected in the longitudinal direction. And an organic coupling structure with the cover assembling means 140 that enables assembly.

このような爆圧遮断カバー１１０は爆薬１を１：１の割合で装填することができるように、通常の爆薬１と同じ長さで形成され、前記爆薬１を部分的に包むことができるように円形断面状に製作され、長手方向に沿って一側が部分的に開放された爆圧誘導路１１１が形成され、前記爆圧誘導路１１１の内側には爆薬１を装填することができる爆薬装填部１１２が形成される。   The explosive pressure blocking cover 110 is formed in the same length as the normal explosive 1 so that the explosive 1 can be loaded at a ratio of 1: 1 so that the explosive 1 can be partially wrapped. An explosive pressure guiding path 111 is formed in a circular cross-sectional shape and partially opened along one side in the longitudinal direction, and the explosive loading in which the explosive 1 can be loaded inside the explosive pressure guiding path 111 is formed. Part 112 is formed.

この時、前記爆圧遮断カバー１１０の外周面には複数の緩衝突起１１３が等間隔で突出して形成されることによって、発破の時、前記爆圧遮断カバー１１０が発破孔２の孔壁にぶつかる時緩衝作用をして爆圧が発破予定線４方に伝達されることを遮断する効果がさらに増加される。   At this time, a plurality of buffer protrusions 113 are formed on the outer peripheral surface of the explosion pressure blocking cover 110 so as to protrude at equal intervals, so that the explosion pressure blocking cover 110 hits the hole wall of the blast hole 2 at the time of blasting. This further increases the effect of blocking the transmission of the explosion pressure to the four blasting lines by buffering.

また、前記爆圧遮断カバー１１０は内側に連続的に二重壁１２０及び三重壁１３０が曲面状に一体化に形成されることによって、爆圧が発破予定線４方向に伝達されることを二重、三重に遮断し、同時に前記爆圧誘導路１１１の方向にさらに集中して伝達するように爆圧の伝達経路を制御することができる。   In addition, the explosion pressure blocking cover 110 is formed such that the double wall 120 and the triple wall 130 are integrally formed in a curved shape on the inner side so that the explosion pressure is transmitted in the direction of the blasting line 4. The transmission path of the explosion pressure can be controlled so that it is interrupted in a heavy and triple manner and at the same time is further concentrated and transmitted in the direction of the explosion pressure guiding path 111.

同時に、前記二重壁１２０及び三重壁１３０の外周面には、図６のように、複数の緩衝突起１２３、１３３が等間隔で形成されることによって、発破の時緩衝作用をし、前記緩衝突起１２３、１３３の各間にはエア層１２５、１３５が形成されることによって、発破作業の時、エアバッグの役割を果たしながら、衝撃を吸収して爆圧が望ましくない方向、即ち、発破予定線４の方に伝達されることをさらに効率的に遮断する。   At the same time, a plurality of buffer protrusions 123 and 133 are formed on the outer peripheral surfaces of the double wall 120 and the triple wall 130 at equal intervals as shown in FIG. The air layers 125 and 135 are formed between the projections 123 and 133, so that during the blasting operation, the role of the airbag is fulfilled, and the impact is absorbed and the explosion pressure is not desired, that is, the blasting schedule. The transmission to the line 4 is blocked more efficiently.

一方、前記複数の爆圧遮断カバー１１０を長手方向に一体化に連結して組み立てることができるようにするカバー組立手段１４０は、前記二重壁１２０の長手方向の一側に、図７のように、結合突起１４１が外側へ延長して一体に突出して形成され、前記二重壁１２０の他側には結合溝１４２が内側へ凹まれて形成される構成からなり、それによって、前記結合突起１４１を他の爆圧遮断カバー１１０の結合溝１４２に挿入する方法で、迅速且つ簡便に爆圧遮断カバー１１０を爆薬１の使用量によって複数を選択的に連結して組み立てて使うことができる。   On the other hand, the cover assembly means 140 that allows the plurality of explosion pressure blocking covers 110 to be integrally connected in the longitudinal direction is assembled on one side of the double wall 120 in the longitudinal direction as shown in FIG. Further, the coupling protrusion 141 extends outward and integrally protrudes, and a coupling groove 142 is formed on the other side of the double wall 120 so as to be recessed inward, whereby the coupling protrusion 141 is formed. By inserting 141 into the coupling groove 142 of another explosive pressure blocking cover 110, a plurality of explosive pressure blocking covers 110 can be selectively connected and assembled according to the amount of explosive 1 used.

ここで、前記結合突起１４１の内側面の前端には傾斜面１４３を有するロック１４４がさらに突出して形成され、前記ロック１４４は結合溝１４２と連結された状態で三重壁１３０を貫通して形成されたロッキング孔１４５に嵌合されて、ロッキングを設定してさらに一体化された堅固な連結組み立て状態を維持することができる。   Here, a lock 144 having an inclined surface 143 protrudes further from the front end of the inner surface of the coupling protrusion 141, and the lock 144 is formed through the triple wall 130 while being connected to the coupling groove 142. It can be fitted into the locking hole 145 to set a locking state and maintain a tightly connected and assembled state.

また、前記爆圧遮断カバー１１０の外周面の一側には爆薬１を包んで固定する連結バンド１１５の一側が一体に固定され、前記連結バンド１１５の他側には接着剤が塗布され、この接着剤の塗布面に離型紙１１６が付着される。   In addition, one side of a connecting band 115 that wraps and fixes the explosive 1 is integrally fixed to one side of the outer peripheral surface of the explosion pressure blocking cover 110, and an adhesive is applied to the other side of the connecting band 115. The release paper 116 is attached to the adhesive application surface.

従って、前記爆薬１を爆圧遮断カバー１１０に１：１の割合で装填した後、前記連結バンド１１５を利用して、爆薬１を包んだ状態で離型紙１１６を剥離して爆薬遮断カバー１１０の外周面に付着すれば前記爆薬１が爆圧遮断カバー１１０から分離しないで一体化された堅固な装填状態を維持することができる。   Therefore, after the explosive 1 is loaded into the explosive pressure blocking cover 110 at a ratio of 1: 1, the release band 116 is peeled off in a state where the explosive 1 is wrapped using the connecting band 115, and the explosive blocking cover 110 is removed. If it adheres to the outer peripheral surface, the explosive 1 can be maintained in an integrated and firm state without being separated from the explosion pressure blocking cover 110.

このように、前記爆圧遮断カバー１１０にそれぞれ爆薬１を装填した後には、複数の爆圧遮断カバー１１０を長手方向に連結して組み立て、この時、必ずまず爆薬１の装填作業を行い、その次に爆圧遮断カバー１１０の組み立て作業を行うことに限定されないで、これら作業の順序を異なるようにして実施しても構わないので、これら順序を異なるようにするだけで、本発明の範疇を逸脱することができない。   As described above, after each of the explosive pressure blocking covers 110 is loaded with the explosive 1, a plurality of explosive pressure blocking covers 110 are connected and assembled in the longitudinal direction. Next, the present invention is not limited to the assembly work of the explosion-pressure blocking cover 110, and the order of these works may be different. Therefore, the scope of the present invention can be achieved only by making these orders different. Cannot deviate.

また、本発明は前記連結して組み立てられた複数の爆圧遮断カバー１１０を発破孔２に挿入するにおいて、爆圧遮断カバー１１０が、図６のように、発破予定線４を向けるように挿入しなければならない。   Further, according to the present invention, when the plurality of explosive pressure blocking covers 110 assembled as described above are inserted into the blasting hole 2, the explosive pressure blocking cover 110 is inserted so that the blasting expected line 4 faces as shown in FIG. Must.

即ち、前記爆圧遮断カバー１１０が発破予定線４を向けるように配置されてこそ、爆薬１の発破の時、前記爆圧遮断カバー１１０は爆圧が発破予定線４に伝達されないように遮断する役割を果たし、それによって、非常に滑らかな発破面を得ることができるとともに、過大掘りを効果的に防止して工事品質を画期的に向上し、震動と騷音を最小化する効果を奏する。   That is, when the explosive pressure blocking cover 110 is arranged so that the expected blast line 4 is directed, the explosive pressure blocking cover 110 blocks the explosive pressure from being transmitted to the planned blast line 4 when the explosive 1 is blasted. It plays a role, and it can obtain a very smooth blasting surface, and it effectively prevents over-digging, dramatically improves construction quality, and minimizes vibration and noise. .

これと同時に、爆圧は部分的に開放して形成された爆圧誘導路１１１の方に順調に誘導されることによって、実際発破しようとする発破領域である発破予定線４の内側方向に大部分の爆圧が伝達されて、発破領域には過大掘りが発生しないで、完璧な発破が行われる特別な効果を提供する。   At the same time, the explosive pressure is smoothly guided toward the explosive pressure guide path 111 that is partially opened, so that the explosive pressure is greatly increased in the direction toward the inside of the blasting planned line 4 that is an actual blasting area. The explosive pressure of the part is transmitted, and there is no excessive digging in the blasting area, providing the special effect that perfect blasting takes place.

このような本発明の爆圧誘導制御装置１００ａは、図８のような他の実施例の形態で実施可能であり、爆圧遮断カバー１１０の構成は同一であるが、爆薬１が１：１の割合で装填されないで、一度に複数の爆薬１が装填されることができる長い長さに製作されることによって、前者のカバー組立手段１４０が省略されることを特徴とし、また前者のような三重壁１３０は省略され、前記爆圧遮断カバー１１０の内側には曲面状に二重壁１２０のみ単独で一体化に形成され、前記二重壁１２０の外周面には複数の緩衝突起１２３が等間隔で突出して形成され、前記緩衝突起１２３の各間にはエア層（１２５）が形成される構成からなる。   Such an explosive pressure induction control device 100a of the present invention can be implemented in the form of another embodiment as shown in FIG. 8, and the constitution of the explosive pressure blocking cover 110 is the same, but the explosive 1 is 1: 1. The former cover assembly means 140 is omitted by being manufactured in a long length that can be loaded with a plurality of explosives 1 at a time without being loaded at a ratio of The triple wall 130 is omitted, and only the double wall 120 is integrally formed in a curved shape on the inner side of the explosion pressure blocking cover 110, and a plurality of buffer projections 123 are formed on the outer peripheral surface of the double wall 120. It is formed to protrude at intervals, and an air layer (125) is formed between the buffer protrusions 123.

さらに、本発明の爆圧誘導制御装置１００ｂは、図９のようなまた他の実施例の形態でも実施可能であり、前者の二重壁１２０及び三重壁１３０とカバー組立手段１４０が省略された非常に簡単な構造である。   Furthermore, the explosive pressure induction control device 100b of the present invention can also be implemented in the form of another embodiment as shown in FIG. 9, and the former double wall 120, triple wall 130 and cover assembly means 140 are omitted. It is a very simple structure.

これは、前記爆圧遮断カバー１１０の構成は前者同一であるが、爆薬１が１：１の割合で装填されないで、一度に複数の爆薬１が装填されることができる長い長さに製作されることを技術的な構成にする。   This is because the configuration of the explosive pressure blocking cover 110 is the same as the former, but the explosive 1 is not loaded at a ratio of 1: 1, and is manufactured to have a long length that allows a plurality of explosives 1 to be loaded at a time. To make it technical.
