Description
본 발명은 터널 및 수직구 발파공사의 단일 자유면 발파 시 다단 장약에 의한 진동제어 발파공법에 관한 것으로, 특히 터널 및 수직구 발파 공사시 심발공과 심발확대공에서 가장 크게 발생되는 지반 진동과 소음을 경감시킬 수 있는 발파 방법에 관한 것이다.The present invention relates to a vibration-controlled blasting method by multi-stage charges when blasting a single free surface of a tunnel and vertical sphere blasting construction. It is about a blasting method which can alleviate.
일반적으로 터널 및 수직구의 암반 굴착 방법은 굴착 면적의 크기, 암반의 상태, 보안 물건과의 거리등에 의해 굴착 방법이 결정된다. 이러한 굴착방법의 기술개선은 발파당 단일 굴착장을 극대화 시키기 위한 심발 발파법과, 굴착면의 손상을 방지시키기 위한 조절 발파법 그리고, 굴착 발파 시 발생되는 지반진동과 소음을 제어하는 방법으로 구분되어 진다.In general, the rock excavation method of the tunnel and the vertical sphere is determined by the size of the excavation area, the condition of the rock, the distance to the security object, and the like. The technical improvement of this excavation method is divided into the heart blasting method to maximize the single excavation site per blasting, the control blasting method to prevent the damage of the drilling surface, and the ground vibration and noise generated during the excavation blasting. .
통상 발파에 의한 터널 굴착 방법은 다음과 같은 3단계로 구분되어 실시되는데, 이를 테면 보조심발공, 심발공, 심발확대공 및 확대공, 주변공, 바닥공등을 일정한 깊이로 천공하는 천공단계와, 상기 천공된 공에 폭약과 뇌관을 채워 장전하는 장전단계 및 장전된 뇌관을 결선하여 발파기로 기폭시키는 단계로 이루어진다.Tunnel excavation method by blasting is generally divided into three stages, such as auxiliary drilling hole, deep hole hole, deep hole expansion hole and enlarged hole, peripheral hole, floor hole, etc. The loading step includes loading the explosives and the primer into the perforated balls and connecting the loaded primers to detonate them with a blasting device.
기폭에 사용되는 뇌관들로서는 순발, 또는 미리세컨드(M.S), 데시세컨드(D.S)의 시차로 기폭되어지는 전기 또는 비전기뇌관을 사용하며, 뇌관의 단차는 20∼500㎳시차를 유지하여 39∼41 단계로 반파하거나, 전기뇌관의 경우에는 다단 발파기를 이용하여 단계를 더욱 세분하여 발파한다.The detonators used for detonation use electric or non-electric detonators detonated by instantaneous or pre-second (MS) and decisive second (DS) parallax. Half blast to step 41, or in the case of electric primer using a multi-stage blasting machine to further break down the step.
그런데 이러한 종래의 발파방법은 장전 방법에 있어 천공된 구멍의 공저에서부터 장전에 필요한 폭약량을 연속적으로 채우고 한 개의 뇌관을 같이 장전하여 뇌관을 기폭시키므로서 단일 뇌관에 의해 폭발되는 폭약량이 많아 발파 진동이 크게 발생되는 문제가 있다.By the way, the conventional blasting method in the loading method from the bottom of the perforated hole to continuously fill the explosive dose required for loading, and by loading one primer together to detonate the primer, there is a lot of explosive charge exploded by a single primer, the blasting vibration There is a big problem.
다시 말해 터널 굴착을 위한 발파가 진행되는 과정에서 중요한 단계는 천공위치에 따라 심발공과 심발확대공이 발파되는 단계와 확대공, 바닥공, 주변공이 순차적으로 발파되는 단계가 있다.In other words, the important steps in the process of blasting for tunnel excavation include the step of blasting the cardiac hole and the cardiac augmentation hole and the step of blasting the enlarged hole, the bottom hole, and the surrounding hole sequentially according to the drilling position.
그 중에서 발파 진동이 가장 크게 발생되는 심발공과 심발확대공의 발파 단계가 전체적인 발파의 성공 여부를 좌우하는 가장 중요한 요소로써, 이 심발 발파작업시 발생되는 초기 발파 진동이 전체 발파 작업에서 가장 크게 발생되어 공해가 발생한다.Among them, the blasting stage of the blasting hole and the deepening hole which causes the most blasting vibration is the most important factor that determines the success of the overall blasting, and the initial blasting vibration generated during the blasting operation is the largest in all the blasting operations. Pollution occurs.
그러나 종래의 기술로는 이를 해결할 수 없고 단순히 공당 장약량을 적게하기 위하여 천공장을 줄이는 방법을 이용하거나, 비 발파 공법으로 굴착 방법을 변경함으로써, 그에 따르는 공사기간의 지연과 경제적인 손실이 발생하는 문제가 있다.However, the conventional technique cannot solve this problem, and it is a problem that delays in construction period and economic loss are caused by simply using a method of reducing the fabrication plant in order to reduce the amount of pledged amount or changing the excavation method by the non-blasting method. There is.
본 발명은 이와 같은 종래의 문제점을 감안하여 이루어진 것으로, 그 목적은 터널 및 수직구 발파 시 발파 진동이 크게 발생되는 심발공과 심발확대공에 다단으로 구분 장약하여 발파하므로서 터널 굴착장을 크게 하면서도 발파 진동을 제어할수있어 터널굴착작업의 능율을 향상시킬 수 있는 터널 및 수직구 발파공사의 다단장약에 의한 진동제어 발파방법을 제공하는데 있다.The present invention has been made in view of the above-described conventional problems, and its object is to make a blasting vibration while increasing the tunnel rig by blasting by dividing it into multiple stages in the deep hole and the deep hole in which the blasting vibration is greatly generated during the blasting of the tunnel and the vertical sphere.

이하 본 발명의 바람직한 실시 예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다. 먼저 도 1은 쐐기형 심발 발파에 적용한 천공 배치도의 정면도를 나타낸 것으로, 도 2 내지 도 5에 나타낸 바와 같이 다른 실시 예에도 적용이 가능하다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, Figure 1 shows a front view of a perforated layout applied to the wedge-shaped heart blasting, as shown in Figures 2 to 5 can be applied to other embodiments.
즉 도1내지 도5에 나타낸 바와 같이 본 발명은 쐐기형(V-Cut), 피라밋형(PYRAMID-CUT), 부채형(FAN-CUT), 수직천공형(NO-CUT), 심발 발파 방법에 있어서 천공방법은 종래의 형태와 같이 천공하고, 보조심발공(1)과 심발공(2), 심발확대공(3)을 다단으로 구분하여 지발뇌관과 폭약을 장전하고 기폭하면, 발파에 의한지반 진동이 현저하게 감소된다.1 to 5, the present invention has a wedge shape (V-Cut), pyramid type (PYRAMID-CUT), fan type (FAN-CUT), vertical drilling type (NO-CUT), heart blasting method In the perforation method, the perforation is performed as in the conventional form, and the secondary heart hole (1), the heart ball hole (2), and the heart enlargement hole (3) are divided into multiple stages to load and detonate the delayed primer and explosive, and the ground caused by the blasting. Vibration is significantly reduced.
도면에서 A는 장약구간이고, B는 비 장약구간을 나타내고 있다.In the figure, A is a charge section, and B represents a non-load section.
이것을 기준으로 지반 진동 저감효과는 단일자유면 발파 시 장약량을 정하는 발파기본식인 하우저 공식 (L = CW3)(L:장약량.C:발파상수. W:최소저항선거리)와 발파 진동식()n(V : 지반진동값. K : 발파진동상수. D : 발파원에서 측정지점까지의 직선거리. W : 지발당 장약량. b : 근거리, 원거리에 따른 상수. n : 발파진동 감쇠지수)에 의하여 검증되어진다.Based on this, the ground vibration reduction effect is Hauser's formula (L = CW 3 ) (L: Dose. C: Blasting Constant. W: Minimum Resistance Line Distance) and Blasting Vibration Type ( n : V: Ground vibration value. K: Blasting vibration constant. D: Linear distance from blasting source to measuring point. Is verified.
상기의 식에 의하여 산출한 표준 장약량은 최소저항선 거리의 3승에 비례하고 발파 진동은 장약량의 자승근 또는 삼승근에 비례하므로, 최소저항선 거리를 적게 하면 장약량이 적어지고 발파진동이 감소하게된다.Since the standard dose calculated by the above formula is proportional to the third power of the minimum resistance line distance and the blasting vibration is proportional to the square root or the triangular root of the dose, the smaller the minimum resistance line distance, the smaller the dose and the blasting vibration are reduced.
본 발명은 단일 천공장에 다단으로 분산시켜 장약하고 장전한 폭약을 순차적으로 기폭되게 하여 발파진동을 감소시키고 발파당 단일 굴착장을 크게 할 수 있으므로 작업능율을 향상 시킬 수 있는 터널굴착발파방법이다.The present invention is a tunnel excavation and blasting method that can improve the work efficiency because it can reduce the blasting vibration and increase the single rig per blast by discharging the loaded and loaded explosives in multiple stages in a single cloth factory.
이와 같이 최소저항선을 적게 하면서도 발파당굴진장을 크게 할 수 있는 터널굴착방법은 현재까지 시전되지 않은 새로운 발파 방법을 제시하는 것이다. 또한 터널굴착발파방법인 쐐기형, 피라밋형, 부채형, 수직천공형 심발공에 본 발명에 의한 방법을 적용하여 다단 장약을 하고 순발 또는 지발뇌관으로 기폭시켜 발파하면 아래표에서 나타낸바와 같이 종래의 발파 방법에 비하여 현저한 진동저감 효과가 발생한다.As such, the tunnel excavation method that can increase the excavation per blast while reducing the minimum resistance line suggests a new blasting method that has not been cast to date. In addition, by applying the method according to the present invention to the tunnel excavation blasting wedge-shaped, pyramid-shaped, fan-shaped, vertical perforated deep-ventilated hole, multi-stage charge and detonate with a quick or delayed primer, as shown in the table below Compared to the blasting method, a significant vibration reduction effect occurs.
예를 들어 서울 지하철 8-11공구 터널 발파 작업의 시공 사례를 근거로 발파작업조건이 같은 경우 종래의 발파방법을 본 발명의 터널 및 수직구 발파공사의 단일자유면 발파시 다단장약에 의한 진동제어 공법으로 적용할때 공당 장약량과 지발당장약량, 발파진동값을 산출하여 비교하면 다음과 같다.For example, if the blasting working conditions are the same on the basis of the construction of the tunnel blasting work of the Seoul Subway section 8-11, the conventional blasting method uses vibration control by multi-stage contract when blasting the single free surface of the tunnel and vertical blasting work of the present invention. When it is applied by the method, it is as follows when calculating the amount of dosage, the amount of delayed dose and the blast vibration value.
발파 작업 조건: 1. 터널 직경 : Φ7mBlasting Working Condition: 1. Tunnel Diameter: Φ7m
2. 굴착 단면적 : 26M22. Excavation cross section: 26M2
3. 단일 천공장 : 1,400 m/m3. Single cloth factory: 1,400 m / m
4. 단일 굴진장 : 1,3004. Single excavation site: 1,300
5. 보안물건과의 거리 : 약 35m5. Distance to security items: about 35m
6. 발파 진동식 : V=62.5(SD)-1.5 6. Blasting vibration: V = 62.5 (SD) -1.5
7. 지발당 장약량 : 최대 1.1kg7. Loading capacity per delay: up to 1.1kg
8. 하우저 공식 : L= CW3 8.Hauser formula: L = CW 3
상기 조건에서 표준발파의 경우 종래의 방법과 본발명에 의한 다단장약방법을 적용하여 천공장에 따른 심발공(1)과 심발확대공(3)의 공당,지발당장약량과 발파 진동값의 비교.In the case of standard blasting under the above conditions, the conventional method and the multi-stage refilling method according to the present invention are applied to compare the dosage of each core, delayed dose and blasting vibration values of the deep hole (1) and the deep hole enlargement hole (3) according to the mill.
도심발파에서 발파조건이 같은 경우 쐐기형 심발 발파에 의한 터널발파시 종래의 방법과 본발명에 의한 다단 장약 방법을 비교하면 다음과 같다.When the blasting conditions are the same in urban blasting, the conventional method and the multi-stage charging method according to the present invention when tunnel blasting by wedge-shaped blasting are compared as follows.
본 발명은 터널발파시 단일굴진장에 따른 천공장의 길이에 따라 심발공(1)과 심발확대공(3)을 소정의 길이로 다단분할하여 장전하므로서 공당, 지발당장약량을 적게하여 발파진동을 현저히 감소시키므로서 발파진동 한계기준값 이내에서 발파작업이 진행될 수 있게 한다.According to the present invention, the blasting vibration is reduced by reducing the amount of pitting sugar and the delay per minute by reloading the multi-stage deep drilling hole (1) and the deep expansion hole (3) in a predetermined length according to the length of the fabric mill according to the single excavation site at the time of tunnel blasting. Significantly reduced, the blasting operation can be carried out within the blast vibration limit value.
이상과 같이 본 발명은 터널발파작업 시 종래의 발파공법을 이용하여 발파진동이 가장 크게 발생되는 심발공과 심발확대공의 최소저항선 거리를 적게 하면서도 발파당 굴진장을 크게할 수 있는 발파공법은 이론적으로는 정립되지어 있으나 현재까지 실시된 사례가 없는 최초의 발파공법인 것이다.As described above, the present invention theoretically provides a blasting method that can increase the excavation length per blast while reducing the minimum resistance line distance between the deepest hole and the deepest hole where the blasting vibration is generated by using the conventional blasting method. Is the first blasting method that has been established but has not been practiced to date.
