Abstract

본 고안은 각종 맨홀의 평상시 또는 작업이나 보수시 각종 사고를 예방할 수 있도록 한 맨홀 안전장치에 관한 것이다.The present invention relates to a manhole safety device that can prevent various accidents during normal operation or maintenance of various manholes.

본 고안에 따르면, 도로변의 하수도 맨홀이나 각종 정화조의 청소나 점검, 작업시 맨홀 뚜껑을 열어 두었을 경우나 부주의로 맨홀 뚜껑이 열렸을 경우 작업자나 사람등이 맨홀에 빠지는 사고를 예방할 수 있도록 한 맨홀 안전장치를 제공하는데 그 목적이 있다. 상기한 목적을 달성하기 위하여 본 고안은 맨홀 밑에 4방향 격자형의 일체로 된 섀시 각 끝부분에 연장관을 연결하고 연장관 끝에 탭을 형성한 것을 연장관의 길이를 조절하여 맨홀 안벽구멍에 밀어 끼우고 연결홈에 설치된 볼트를 조임으로써 섀시본체와 연장관 각 부분이 일체가 되고 이 새시 각 부분이 맨홀안벽에 지지되어 직 하중을 견딜 수 있도록 하여 안전장치를 이루고 필요시 볼트를 풀어 간편하게 해체할 수 있는 것을 특징으로 하는 맨홀내 안전장치를 제공함으로써 달성할 수 있다.According to the present invention, when the manhole cover is left open during the cleaning or inspection of the sewer manhole or various septic tanks on the roadside, or when the manhole cover is inadvertently opened, the manhole safety can be prevented from falling into the manhole. The purpose is to provide a device. In order to achieve the above object, the present invention connects the extension tube to each end of the integrated chassis of four-way lattice under the manhole, and forms a tab at the end of the extension tube, and adjusts the length of the extension tube to the manhole inner wall hole. By tightening the bolt installed in the groove, each part of the chassis body and the extension tube are integrated, and each part of the chassis is supported by the manhole inner wall to withstand the direct load. This can be achieved by providing a safety device in the manhole.

Description

설치가 간편한 맨홀안전장치{omitted}Easy to install manhole safety device {omitted}

본 고안은 맨홀 안전장치에 관한 것으로, 맨홀 밑에 격자형의 일체로 된 새시 각 끝부분에 연장관을 연결하고 연장관 끝부분에 설치된 탭을 연장관의 길이를 조절하여 맨홀안벽 구멍에 끼우고 볼트를 이용 고정시킴으로써 격자형 섀시와 연장관 각 부분이 일체가 되고 이 섀시 각 부분이 맨홀안벽에 지지되는 안전장치를 설치한 후 맨홀 뚜껑을 덮음으로써 만일의 경우 발생할 수 있는 사고를 미연에 방지할 수 있도록 한 맨홀 안전장치에 관한 것이다.The present invention relates to a manhole safety device, which connects the extension tube to each end of the grid-like integrated chassis under the manhole, and adjusts the length of the extension tube to the manhole inner wall hole and fixes it using bolts. Manhole safety to prevent accidents that may occur in case of accident by installing a safety device in which the lattice chassis and the extension tube are integrated and each chassis is supported on the manhole wall. Relates to a device.

일반적으로, 종래의 각종 상.하수도용 맨홀은 안전장치 없이 주철재 뚜껑을 덮어 사용하는 것이 대부분이며 안전장치로는 무거운 재질로 하거나 때때로 시건장치를 하여 장비나 도구에 의하지 않고서는 열지 못하도록 하는 정도이나, 이같은 방법으로는 어느정도 맨홀뚜껑을 여는 것은 방지할 수 있겠으나 안전장치가 없으므로 위험요인은 항상 상존해 있는 실정이다. 보통 깊은맨홀의 경우 3~7m정도 되는 실정이며, 만약 퇴적물의 청소나 점검시 아무런 안전장치없이 맨홀이 개방됨으로써 작업자에 위험을 초래할 수 있음은 물론 범죄자로 인한 사체 유기등에 이용될 소지가 있는등 우리사회에 안전이 취약한 부분중의 하나이다.In general, various conventional manholes for water and sewage are covered with a cast iron cover without a safety device, and the safety device is a heavy material or sometimes a locking device that prevents it from being opened without using equipment or tools. In this way, opening the manhole cover to some extent can be prevented, but since there is no safety device, risk factors always exist. In general, the deep manhole is about 3 ~ 7m, and if the manhole is opened without any safety device when cleaning or inspecting the sediment, it may cause danger to the worker and may be used for dead body of criminals. It is one of the areas where safety is vulnerable to society.

또한 상가나 주택등에 설치되는 정화조(오수처리시설)의 경우 3~5m미터정도(기성제품 2.4m정도)로 깊고 내용물이 유독하고 미생물 활성화를 위한 장치(여재, 에어이송관, 소포수관등)등이 설치되어 있어 사고가 발생할 경우 인명피해로 이어질 우려가 있으며 현행 정화조 설치.관리에 관해 규정하고 있는 오수.분뇨및축산폐수의처리에 관한법률 시행규칙 제15조(오수처리시설 설치기준) 및 동법 시행규칙 제21조(정화조 설치기준)에 의하면 맨홀 안전에 관해 "뚜껑은 밀폐할 수 있어야 하며 잠금장치를 설치하거나 뚜껑밑에 격자형의 철망등을 설치하여 안전하게 설치하여야 한다"라고 규정하고 있으나 실제 설치되는 정화조 맨홀에는 철근을 이용한 십자형의 고정식이나 맨홀 상부에 철띠에 나사를 설치하여 고정시키고 있으며, 기성품의 경우 본체에 고정시켜 십자형으로 만드는등 그 설치되는 것이 안전측면에서는 어느정도 만족하나 유지보수시에는 이러한 장치를 제거하고 내부로 들어가서 점검할 수 있어야 하나 불편하고 아예 들어갈 수 없는 구조로 되어있는등의 문제점이 있었다.In the case of septic tanks (sewage treatment facilities) installed in shopping malls and houses, they are 3 to 5 m long (about 2.4 m for ready-made products) and are deep and toxic. If there is an accident, it may lead to human injury, and the Enforcement Rule of the Act on the Treatment of Sewage, Manure and Livestock Wastewater, which prescribes the current installation and management of septic tanks, and the implementation of the same law. Rule 21 (Septic Tank Installation Criteria) stipulates that the manhole safety should be "securely sealed and installed securely by installing a locking device or installing a grid-type wire mesh under the lid". The septic tank manhole is fixed with cross bars using reinforcing bars or by installing screws on the upper part of the manhole. There was a problem such that it is in the installation safety aspects in a satisfactory extent during maintenance, the structure can not fit one uncomfortable and even be able to remove these devices and checks to penetrate that makes such a cross.

이에 본 고안의 목적은 종래의 문제점을 해결하기 위한 것으로, 평상시에는 작업자나 천재지변으로 인한 가축이나 사람의 추락을 방지하기 위해 맨홀 밑에 격자형의 일체로된 섀시 각 끝부분에 설치된 연장관을 맨홀 안벽구멍에 끼워 볼트로 조임으로써 격자형 섀시가 안벽에 지지되어 고정됨으로써 직 하중을 받게 하여 안전장치를 이루어 만일의 경우에 맨홀뚜껑이 열려 일어날 수 있는 인명피해등을 예방하여 항시 안전을 유지하고 작업이나 보수시에는 맨홀 뚜껑을 열고 안전장치의 볼트를 풀어줌으로써 간편하게 탈거가 될 수 있으며 또한 섀시 간격은 200mm 이하로 유지하고 필요시 중간중간에 섀시를 보강하여 더 촘촘하게 설치할 수 도 있어 건축설비기준의 안전기준을 준수하여 여러 경우에 발생될 수 있는 사고를 미연에 방지하고자 하는데 그 목적이 있다.Therefore, the purpose of the present invention is to solve the conventional problems, usually in the manhole inner wall of the extension pipe installed at each end of the grid-like integrated chassis under the manhole to prevent the fall of livestock or humans due to workers or natural disasters The grid-shaped chassis is supported and fixed to the inner wall by fastening with bolts to be inserted into the holes to receive a direct load, thus providing a safety device.In case of emergency, the manhole cover can be opened to prevent personal injury that may occur and to maintain safety at all times. When repairing, it can be easily removed by opening the manhole cover and releasing the bolts of the safety device.Also, the chassis distance can be kept less than 200mm and if necessary, the chassis can be reinforced to install more closely. In order to prevent accidents that may occur in many cases, There is a purpose.
