석면 비산방지와 함께 석면함유 건축재의 안전한 해체방법 및 그 시스템{Method and System for Removal Building Materials with Preventing Asbestos Dispersing}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of dismantling asbestos-

본 발명은 주택, 빌딩 등 건축물에 설치된 석면을 함유한 건축재를 해체하는 방법에 관한 것이며, 보다 구체적으로는 건축물에 설치된 석면을 함유한 건축재를 해체할 때 건축재에 함유된 석면의 비산으로 인한 작업장 주변의 오염 및 작업환경의 유해요소를 제거하여 안전하게 주택, 빌딩 등 건축물에 설치된 석면함유 건축재를 해체하는 방법 및 그 시스템에 관한 것이다.The present invention relates to a method for dismantling a building material containing asbestos installed in a building such as a house or a building, and more particularly, to a method for dismantling a building material containing asbestos, And removing the harmful elements of the working environment to safely dismantle asbestos-containing building materials installed in buildings such as houses and buildings, and a system thereof.

석면(asbestos)은 기계적인 강도가 우수하고 또한 불연성, 단열성, 내구성, 절연성, 보온성이 뛰어나 건축재료로서 방화재, 내화재, 보온재, 단열재, 지붕재(슬레이트), 전기절연재 등 여러 산업분야에서 다양한 용도로 오래전부터 널리 사용되어 왔다.Asbestos has excellent mechanical strength and is excellent in nonflammability, insulation, durability, insulation, and warmth. It is used in various industrial fields such as fireproofing, refractory, insulation, insulation, roofing (slate) It has been widely used since long ago.

그러나 석면분진을 장기간 호흡기를 통해 흡입하게 되면 석면폐(폐선유증), 폐암, 악성중피종을 유발하는 등 석면이 인체에 유해한 사실이 알려지면서 석면을 건축재 등으로 시공하는 것을 금지하고 있으며, 우리나라도 1991년부터 본격적으로 석면사용의 규제가 발표되면서 더 이상 건축물에 발포석면을 사용하는 일은 거의 없으나, 이미 오랜 전에 지하철과 같은 공공구조물, 주택, 빌딩 같은 건축물에 시공된 석면함유 건축재가 시간이 지나면서 석면이 유출되어 비산하는 문제점이 발생하여 이들 석면함유 건축재를 해체하여야 할 필요성이 크게 대두되고 있다.However, when asbestos dust is inhaled through a long-term respiratory system, it is known that asbestos is harmful to the human body such as asbestosis (lung scarring), lung cancer, and malignant mesothelioma. Thus, it is prohibited to apply asbestos to building materials, Since asbestos use regulations have been announced in earnest, there has been little use of foamed asbestos in buildings. However, asbestos-containing building materials built into buildings such as subways, public buildings, It is necessary to dismantle these asbestos-containing building materials.

상기한 바와 같이, 석면은 인체에 매우 유해하여 석면함유 건축재를 해체할 경우에도 비산으로 인하여 주변 환경을 오염시켜 2차 공해를 유발하거나 작업장의 작업환경을 악화시켜 작업자의 건강을 해칠 우려가 있으므로 석면함유 건축재를 해체하는 작업과정에서도 석면의 비산방지를 엄격하게 규제하고 있다.As described above, since the asbestos is very harmful to the human body, even if the asbestos-containing building material is dismantled, it may pollute the surrounding environment due to scattering, thereby causing secondary pollution or deteriorating the working environment of the workplace, In the course of dismantling construction materials containing asbestos, the prevention of the scattering of asbestos is strictly regulated.

석면함유 건축물의 해체 작업에 따른 선행기술로는 국내공개특허공보 공개번호 제10-2004-0006204호 및 국내공개특허공보 공개번호 제10-2009-0104225호에는 석면제거구역을 외부와 격리시키고 습윤제를 살포함과 동시에 및 배기장치를 이용하여 석면을 제거하는 공법을 개시하고 있고, 국내공개특허공보 공개번호 제10-2009-0076082호에는 침투성이 높은 석면처리제를 살포한 다음 석면을 제거하는 공법을 개시하고 있으며, 이들 선행기술은 작업구역과 외부환경을 격리하고 석면비산의 방지를 위해 석면부위에 습윤제의 살포를 주된 기술로 하고 있으나 습윤제의 살포에 의해서는 해체작업을 하는 과정에서 끊임없이 비산하는 석면을 완전히 제거할 수 없는 결점이 있다.Prior art related to the dismantling of asbestos-containing buildings is disclosed in Korean Patent Laid-Open Publication No. 10-2004-0006204 and Korean Patent Laid-Open No. 10-2009-0104225, in which asbestos removal area is isolated from the outside, Discloses a method for removing asbestos by simultaneously and simultaneously discharging asbestos, and discloses a method for removing asbestos by spraying an asbestos treating agent having high permeability in Korean Patent Laid-Open Publication No. 10-2009-0076082 These prior art isolate the working area from the external environment and spray the wetting agent to the asbestos area in order to prevent asbestos scattering. However, when the wetting agent is sprayed, the asbestos There is a drawback that it can not be removed completely.

또 국내공개특허공보 공개번호 제10-2009-0123446호에서는 지하철 천장을 워터젯을 이용하여 물을 강력하게 분사하면서 석면을 제거하는 제거장비를 개시하고 있으며, 이는 지하철 천장, 케이블 등에 축적된 석면먼지를 주로 세척하는 기술이므로 건축재의 해체작업에는 적용할 수가 없는 기술이라 하겠다.In addition, Korean Patent Laid-Open Publication No. 10-2009-0123446 discloses a removing device for removing asbestos while spraying water on a ceiling of a subway by using a water jet. This removes asbestos dust accumulated in a ceiling of a subway, Because it is mainly cleaning technology, it can not be applied to the dismantling work of construction materials.

본 발명은 상기한 선행기술의 문제점을 개선하여 주택, 빌딩 등 건축물에 설치된 석면을 함유한 건축재를 해체하는 방법 및 그 시스템을 제공하는 것을 목적으로 하며, 보다 구체적으로는 석면이 함유된 건축재를 해체할 때 작업 초기부터 작업을 완결하는 동안 끊임없이 비산하는 석면을 포집처리에 의해 실시간으로 비산석면을 제거하는 수단을 채용하여 작업장 주변의 오염 및 작업환경의 유해요소를 완벽하게 제거하여 안전하게 주택, 빌딩 등 건축물에 설치된 석면함유 건축재를 해체하는 방법 및 그 시스템을 제공하는 것을 목적으로 하는 것이다.It is an object of the present invention to provide a method and system for dismantling construction materials containing asbestos installed in buildings such as houses and buildings by improving the problems of the prior art described above and more particularly to a method of dismantling construction materials containing asbestos Asbestos is removed from the beginning of the work from the beginning of the work by means of collecting asbestos that is constantly scattered and collected in real time, And to provide a method and a system for dismantling asbestos-containing building material installed in a building.

본 발명은 상기한 목적을 달성하기 위하여 채용하는 구체적인 수단으로는 먼저, 석면함유 건축재가 시공된 건축물에서 석면함유 건축재 해체구역(A)을 설정하면, 상기 설정된 해체구역의 바닥 및 공간을 외부와 격리(차단)되게 차단막(1)을 설치(보양시설 설치)한 다음, 해체구역의 공간 내부를 저압화 하면서 내부의 비산석면 등의 집진 및 배기를 위하여 집진배기장치(2)를 설치함과 동시에 포집제 공급라인(3)과 분무노즐(압축공기에 의해 액체를 분무하는 방식, air spray, 4)로 구성된 포집제분무장치를 해체구역(A)의 내부에 설치하되, 분무노즐(4)은 천장과 일정간격이 유지되도록 설치한다.In order to achieve the above object, the present invention provides a method of disposing asbestos-containing building material in an asbestos-containing building material disassembly zone A, The dust collecting and discharging device 2 is installed for the dust collecting and exhausting of the inside scattered asbestos while making the inside pressure of the dismantling area low, A collection spraying device composed of a supply line 3 and a spray nozzle (a method of spraying liquid by compressed air, air spray, 4) is installed inside the disassembly zone A, As shown in FIG.

본 발명에서 해체구역(A)의 바닥 및 공간을 외부와 격리(차단)되게 차단하는 차단막(1)은 합성수지 시트를 사용하며, 합성수지 시트는 작업환경에서 파손 및 손상되지 않을 정도의 충분한 강도를 가진 것을 사용하고, 구체적으로는 비닐시트 등이 선택되며, 차단막으로 사용하는 시트는 두께 0.08㎜ 이상, 바닥에 사용하는 시트는 두께 0.15㎜ 이상의 것을 사용하는 것이 바람직하고, 시트는 2중으로 하여 차단막(1)을 설치하는 것이 바람직하다.In the present invention, the shielding film 1 which blocks the bottom and the space of the disassembly zone A from the outside is used as the synthetic resin sheet, and the synthetic resin sheet has a sufficient strength A sheet to be used as a barrier film is preferably 0.08 mm or more in thickness and a sheet to be used on the bottom is preferably 0.15 mm or more in thickness. As shown in Fig.

또 외부와 격리된 해체구역(A)의 배기 측에 고성능 에어필터를 장착한 집진배기장치(2)를 설치하여 격리된 해체구역 내부를 항상 부압(외부보다 저압)으로 유지하면서 석면의 비산방지 내지 비산된 석면을 배기시켜 제거한다.In addition, a dust collecting and discharging device 2 equipped with a high-performance air filter is provided on the exhaust side of the dismantling area A isolated from the outside to keep the inside of the dismantling area always at a negative pressure (lower pressure than outside) Exhausted asbestos is removed.

그리고 본 발명의 특징 중 하나인 포집제분무장치는 격리된 해체구역(A) 내부에 설치되어 해체작업을 하는 공간 내부에 분무노즐(4)에 의해 포집제를 일정농도로 안개처럼 분무시키며, 포집제의 분무는 해체작업 초기부터 해체작업이 완료될 때까지 연속 또는 간헐적으로 분무하도록 제어하여, 해체작업이 진행되는 과정에서 끊임없이 비산하는 석면이 포집제의 작용으로 실시간 포집, 낙하되면서 격리된 해체구역(A) 공간 내부의 비산석면을 제거시킴으로써 석면의 비산을 거의 완벽하게 방지할 뿐 아니라 격리된 작업장 내부의 작업환경도 개선하는 효과도 있다.One of the features of the present invention is that the collecting and spraying apparatus is installed inside the dismantling area A and spraying the collecting agent in a certain concentration like mist by the spray nozzle 4 in the space for dismantling work, The aspiration system is controlled so as to continuously or intermittently spray until the dismantling operation is completed from the beginning of the dismantling operation to the dismantling section (A) Removing asbestos from the inside of the space almost completely prevents the scattering of asbestos and also improves the working environment inside the isolated workplace.

본 발명의 포집제분무장치에 있어서, 포집제 공급라인(3)은 설치와 해체의 용이성을 위하여 유연성있는(플렉시블) 고무 또는 합성수지 호스로 이루어진 포집제 공급호스(3′) 및 압축공기 공급호스(3″)로 구성되며, 포집제 공급라인(3)의 포집제 공급호스(3′) 및 압축공기 공급호스(3″)에 분무노즐(4)을 1 내지 2m 간격을 두고 장착하되, 분무노즐(4)의 방향은 격리된 공간 내부 및 천장 등으로 포집제가 분무 될 수 있도록 여러 방향으로 장착하며, 포집제분무장치를 해체구역(A) 공간 내부에 설치할 때 분무노즐(4)이 천장으로부터 10~20㎝ 정도 간격이 유지될 수 있게 설치한다. In the collecting agent spraying apparatus of the present invention, the collecting agent supply line 3 is provided with a collecting agent supply hose 3 'made of a flexible rubber or synthetic resin hose for easy installation and disassembly, 3 "), and a spray nozzle (4) is attached to the collecting agent supply hose (3 ') and the compressed air supply hose (3") of the collecting agent supply line (3) at intervals of 1 to 2 m, (4) is installed in various directions so that the collecting agent can be sprayed to the inside of the isolated space and the ceiling or the like, and the spray nozzle (4) is installed in the dismantling area (A) It is installed so that the interval of about 20 cm can be maintained.

본 발명에서 사용하는 상기 포집제 공급라인(3)의 포집제 공급호스(3′) 및 압축공기 공급호스(3″)에 분무노즐(4)이 장착되며, 분무노즐(4)은 에어펌프에 의해 포집제를 액적 20~40㎛ 크기의 안개상태(무화)로 분무시키는 에어노즐(압축공기에 의해 액체를 분무하는 방식, air spray)이며, 시판되는 제품(액체를 최대 12ℓ/hr 분무하는 국제노즐社 HM시리즈 제품)으로부터 쉽게 구입할 수가 있다.The spray nozzle 4 is mounted on the collecting agent supply hose 3 'and the compressed air supply hose 3' 'of the collecting agent supply line 3 used in the present invention. The spray nozzle 4 is connected to the air pump Is an air nozzle (spraying liquid by compressed air, spraying liquid) 20 ~ 40㎛ in size with fog (atomization), and it is a commercial product (an international Nos. ≪ / RTI > HM series).

포집제는 물을 사용하며, 비산되는 미세한 물방울은 비산석면과 서로 반대되는 전하를 띠기 때문에 20~40㎛ 크기의 미세한 물방울에 비산석면은 쉽게 포집되어 낙하 됨으로써 해체작업이 진행되는 과정에서 작업장 내부에 끊임없이 비산하는 석면을 실시간으로 완벽하게 제거할 수 있다.Since the fine water droplets that are scattered form a charge opposite to that of the non-asbestos surface, the asbestos is easily collected in fine droplets of 20 to 40 μm size and falls down. In the process of dismantling, Asbestos that is constantly scattered can be completely removed in real time.

또 본 발명에서는 해체작업 시작 전에 석면비산을 방지하기 위하여 석면을 해체하려는 부위(천장 등)에 1차적으로 습윤제를 살포하는 별도의 습윤제 살포수단을 포함하며, 습윤제 살포수단은 본 발명의 기술분야에 알려진 통상의 습윤제 살포수단을 채용하는 것이므로 구체적인 설명은 생략한다.Further, the present invention includes a separate wetting agent spraying means for spraying the wetting agent primarily on the site (ceiling, etc.) where the asbestos is to be dismantled to prevent asbestos scattering before the dismantling work is started, A known wetting agent spraying means is employed, and thus a detailed description thereof will be omitted.

상기한 본 발명은 석면이 함유된 건축재를 해체할 때 작업 초기부터 작업을 완결하는 동안 끊임없이 비산하는 석면을 분무되는 물(포집제)에 의해 포집처리함으로써 비산석면을 실시간 완벽하게 제거할 수 있으므로 외부환경으로 비산석면의 누출 방지를 보다 개선하는 효과가 있을 뿐 아니라 작업환경의 유해요소를 실시간으로 제거해 줌으로써 주택, 빌딩 등 건축물에 설치된 석면함유 건축재를 안전하고, 효과적으로 해체할 수 있다.In the present invention, when dismantling a building material containing asbestos, it is possible to completely remove the non-asbestos surface in real time by collecting the asbestos scattered continuously during the completion of the work from the work with the sprayed water (collecting agent) Asbestos asbestos can be prevented from leaking by the environment, and it is possible to safely and effectively dismantle asbestos-containing building materials installed in buildings such as houses and buildings by removing harmful elements of the working environment in real time.

도 1은 본 발명의 포집제분무장치가 설치된 석면함유 건축재의 해체시스템의 개략도이다.BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view of a disassembly system of an asbestos-containing building material provided with a collecting spraying apparatus of the present invention.
