Description

조립식 맨홀의 시공방법{Method for constructing of assembly type manhole}Method for constructing of assembly type manhole}

본 발명은 조립식맨홀의 시공방법에 관한 것으로, 더욱 상세하게는 상,하방향으로 각각 분리 제작되어진 콘크리트 구축물을 단계적으로 적층시키는 형태로 결합하여 그 시공시간을 단축시킬 수 있도록 함과 아울러, 상기 각각의 콘크리트부재가 결합되는 부위를 밀봉하여 그 측방으로 부터의 외력에 의한 맨홀조립체의 결합상태가 변형되거나 누수되는 것을 방지할 수 있도록 한 조립식맨홀의 시공방법에 관한 것이다.The present invention relates to a method for constructing a prefabricated manhole, and more particularly, to combine the concrete constructions that are separately manufactured in the up and down directions in a step-by-step manner to shorten the construction time, respectively, It relates to a construction method of the prefabricated manhole to seal the site where the concrete member is coupled to prevent the deformation or leakage of the coupling state of the manhole assembly by the external force from the side.

통신케이블이나 전력선등과 같은 각종 지하매설물의 보수관리를 위한 맨홀을 구축함에 있어서는, 통상적으로 지하 굴착작업후에 기초공사를 시공하고 맨홀의 형태를 이루기 위한 철골을 시공하여 그 주위에 형틀을 형성시킨 후, 이 형틀내에 시멘트몰탈을 주입시켜 콘크리트구축물을 양생하는 방법이 이용되고 있다.In constructing manholes for the maintenance and management of various underground works such as communication cables and power lines, after the excavation work, underground works are usually constructed, and steel frames for manholes are formed to form molds around them. A method of curing concrete structures by injecting cement mortar into the mold has been used.

그러나 이러한 현장에서의 콘크리트 타설방법에 의한 맨홀의 구축방법은, 1개의 맨홀을 구축함에 있어서도 다수의 숙련공이 필요하고 또한, 그 콘크리트구축물의 양생과정에서 많은 시간과 노력이 요구되는 문제점이 있다.However, the construction method of the manhole by the concrete placing method in the field, there is a problem that a large number of skilled workers are required to build one manhole, and a lot of time and effort is required in the curing process of the concrete structure.

따라서 이러한 문제점을 보완하기 위하여, 근래에는 내부에 수용공간이 형성되도록 맨홀암거를 저면판과 상면판 및 복수개의 측면판으로 분리 구성하고, 상기 저면판의 상부표면과 상면판의 하부표면에는 각각 감합요구가 형성되도록 하고, 각 측면판의 상,하단부에는 감합돌출턱이 형성되도록 공장에서 미리 제작하고 이를 현장에서 상호 결합되도록 하는 조립식 맨홀암거가 대한민국 실용신안공보 공고번호 90-3520호를 통하여 이미 공지되어 있다.Therefore, in order to compensate for these problems, in recent years, the manhole culvert is divided into a bottom plate, a top plate and a plurality of side plates so that an accommodation space is formed therein, and the upper surface of the bottom plate and the bottom surface of the top plate are respectively fitted. Prefabricated manhole culverts are made in advance in the factory so that the fitting projections are formed at the upper and lower ends of each side plate, and they are mutually combined at the site, and are already known through the Korean Utility Model Publication No. 90-3520. It is.

이러한 구성을 갖는 상기 조립식 맨홀암거는 그 설치방법이, 먼저 시공위치를 굴착하여 지상공동구를 형성하고 이렇게 형성된 지하공동구의 바닥에 저면판을 설치한다.The prefabricated manhole chamfer having such a configuration is the installation method, first excavating the construction position to form a ground cavity, and the bottom plate is installed on the bottom of the underground cavity thus formed.

그리고 저면판상에 각 측면판이 조립되도록 하여 상기 측면판의 상단부에 상면판이 조립되도록 하여 암거조립체를 형성하고, 이렇게 형성된 암거조립체의 외측에 토사로 되메우기를 하게 된다.Then, each side plate is assembled on the bottom plate so that the top plate is assembled at the upper end of the side plate to form a culvert assembly, and the backfill is filled with soil on the outside of the culvert assembly.

그런데 이와 같은 종래의 조립식 맨홀암거에 있어서는, 토사의 압력이 집중적으로 작용하게 되는 각 측면판은 그 상/하단부에 소정길이로 형성된 감합요구 및 감합돌출턱외에는 별도의 결합수단이 마련되어 있지 않고 있어 그 결합부위에 응력이 집중될 경우 맨홀 암거조립체가 변형될 우려가 크다는 문제점이 있고 또한, 상기 암거조립체는 그 결합부위에 필연적으로 소정의 간극이 발생하게 됨으로서 이렇게 발생되어진 간극을 통하여 지하공동구의 굴착과정에서 발생된 지하수가 맨홀의 수용공간내부로 유입되는 누수문제가 있다.By the way, in the conventional prefabricated manhole culvert, each side plate to which the pressure of the soil is concentrated intensively has no separate coupling means other than the fitting request and the fitting protrusion formed at a predetermined length in the upper and lower ends thereof. When stress is concentrated at the coupling site, there is a problem that the manhole culvert assembly is highly deformed. In addition, the culvert assembly inevitably generates a predetermined gap at the coupling site, and thus excavation process of the underground cavity through the gap thus generated. There is a leakage problem that the groundwater generated in the inflow into the receiving space of the manhole.

이에 본 발명은 상기의 제반 문제점을 해소시키기 위해 안출된 것으로, 본 발명은 상,하방향으로 각각 분리 제작되어진 콘크리트 구축물을 단계적으로 적층시키는 형태로 결합하여 그 시공시간을 단축시킬 수 있도록 함과 아울러, 상기 각각의 콘크리트부재가 결합되는 부위를 밀봉하여 그 측방으로 부터의 외력에 의한 맨홀조립체의 결합상태가 변형되거나 누수되는 것을 방지할 수 있도록 한 조립식맨홀의 시공방법을 제공하는데 그 목적이 있는 것이다.Accordingly, the present invention has been made to solve the above problems, the present invention is combined to form a step-by-step stacking the concrete building, which is separately produced in the up and down directions, so as to shorten the construction time It is an object of the present invention to provide a method of constructing a prefabricated manhole that seals a portion to which each concrete member is coupled to prevent deformation or leakage of the state of engagement of the manhole assembly due to external force from the side thereof. .
