UNDERGROUND EXCAVATION CONSTRUCTION METHOD
The present invention provides a construction method for connecting an existing underground manhole structure using a non-cut-and-cover construction method. The purpose of the present invention is to provide a construction method for connecting an existing underground manhole structure using a non-cut-and-cover construction method, capable of reducing construction costs by reducing a construction period. In addition, the construction method for connecting an existing underground manhole structure enables a construction of connecting a new underground pipe conduit to an existing underground manhole structure to connect a power line and the like to the existing underground manhole structure, to be conducted in a steel pipe pressing and propelling construction method by the non-cut-and-cover construction method. Therefore, the construction method for connecting an existing underground manhole structure does not need to additionally block a road traffic, thereby reducing costs. The construction method for connecting an existing underground manhole structure includes: a first step of horizontally pressing and propelling a first steel pipe (100) in order; a second step of vertically pressing and propelling a second steel pipe (200) in order; and a third step of completing a vertical structure (300) by expanding a new space unit in the lower part of an existing underground manhole structure (104).
본 발명의 목적은 기존 지중 맨홀 구조물에 전력선 등을 연결하기 위해 새로운 지중 관로를 기존 지중 맨홀 구조물에 연결시키는 공사를 비개착식 공법에 의한 강관압입추진공법으로 진행할 수 있게 하여 별도의 도로 교통을 차단하지 않아도 되고, 그에 따른 경비를 절감할 수 있으며, 공사 기간을 단축시켜 공사 비용을 절감할 수 있게 한 비개착식 공법에 의한 기존 지중 맨홀 구조물 연결 설치 시공방법을 제공한다.
