Description

세그멘트식 콘크리트지하구조물 구축용 굴착추진장치 및 이를 이용한 구축방법{Excavation Propulsion Apparatus of Underground Concrete Structure on Segement Construction Base}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excavation propulsion device for constructing an underground structure of a segment type concrete,

본 발명은 세그멘트식 콘크리트지하구조물 구축용 굴착추진장치에 관한 것으로서, 보다 상세하게는 굴착추진장치의 하중지지부 외측을 원형관 형태의 외력지지관으로 감싸도록 배치시킴으로써, 기존의 빔부재를 사용하던 방식에 비해 형태를 자유롭게 제작할 수 있고, 구조적 안정성 및 큰 하중을 견딜 수 있는 지지력이 확보되도록 하는 세그멘트식 콘크리트지하구조물 구축용 굴착추진장치에 관한 것이다.The present invention relates to an excavation propulsion device for constructing a concrete concrete underground structure, and more particularly, to an excavation propulsion device for constructing a concrete concrete underground structure by arranging an outer side of a load- And to provide a supporting structure capable of withstanding the structural stability and the large load. The present invention relates to an excavation propulsion device for constructing a concrete concrete underground structure.

지하에는 치수, 통신케이블 등의 설치 등의 목적으로 콘크리트타설공법으로 콘크리트지하구조물 설치하고 있으며, 이들 콘크리트지하구조물의 한 형태로 구조물천정부와, 구조물천정부와 협조하여 디귿자 형태를 이루도록 구조물천정부로부터 절곡 형성된 구조물좌측벽부 및 구조물우측벽부를 갖는 구조가 있다.Concrete underground structures are installed by concrete casting method for the purpose of installation of dimensions and communication cables in the basement. In the form of these concrete underground structures, they are bent and formed from the ceiling of the structure so as to form a diaphragm in cooperation with the structure ceiling and the structure ceiling. A structure left side wall portion and a structure right side wall portion.

본 명세서에서 콘크리트타설공법이란 종래 널리 알려진 바와 같이 거푸집설치작업, 철근배근작업, 콘크리트타설작업, 양생작업, 거푸집해체작업을 통해 콘크리트구조물을 형성하는 공법을 말한다.As used herein, the concrete pouring method refers to a method of forming a concrete structure by molding work, reinforcement work, concrete pouring work, curing work, and mold disassembly work, as is well known in the art.

도로, 철도 등과 같이 구조적으로 또는 사용상의 이유로 이전이나 개착(開鑿)이 어려운 지상시설물을 횡단하여 콘크리트지하구조물을 설치하고자 할 때에는 비개착공법(非開鑿工法)이 널리 이용되고 있다.Non-opening method is widely used when concrete underground structures are to be installed across ground facilities that are difficult to transfer or open due to structural or usage reasons such as roads and railways.

비개착공법은 보통 횡단하고자 하는 지상시설물의 양 측에 추진기지와 도달기지를 각각 굴착하고 추진기지와 도달기지를 작업공간으로 활용하여 지상시설물을 건드리지 않고 콘크리트타설공법으로 콘크리트지하구조물을 구축하는 방법으로 이루어진다.In the non-installation method, a propulsion base and a reaching base are excavated on both sides of a ground facility to be traversed, and a concrete underground structure is constructed by using a propulsion base and a reaching base as a work space without touching ground facilities Lt; / RTI >

이러한 비개착공법에 의한 콘크리트지하구조물 구축공법으로는 견인공법(Front Jacking)과 강관루프공법 등이 있다.The construction methods of concrete underground structures by such non-installation methods include a front jacking method and a steel pipe loop method.

견인공법은 구조물설치 장소의 인접 지역에서 콘크리트지하구조물을 형성한 후 견인과 굴착작업을 반복하여 지하에 구조물을 설치하는 공법이다.The towing method is a method of constructing a concrete underground structure in the adjoining area of the structure installation site and then repeating traction and excavation work to install the structure underground.

견인공법은 콘크리트지하구조물의 규모가 커지게 되면 견인에 제약이 따르게 되고 큰 작업장이 필요해진다는 문제점이 있었다.The towing method has a problem that when the size of the concrete underground structure becomes large, the traction is restricted and a large workshop is required.

강관루프공법은 구조물이 형성될 지중에 미리 강관을 순차적으로 압입 연결하여, 강관 루프를 형성하고, 강관 루프의 안쪽의 내부 토사를 전부 제거하고 구조물을 구축하는 방법으로 이루어지는 바, 이를 도40 내지 도42를 참조하여 상세히 설명하면 다음과 같다.In the steel pipe-loop method, a steel pipe is successively press-fitted in advance into the ground where a structure is to be formed to form a steel pipe loop, and all of the internal gravel inside the steel pipe loop is removed to construct a structure. 42 will be described in detail as follows.

도41, 도42 및 도43은 각각 종래의 강관루프공법을 도시한 도면이다.41, 42 and 43 are views showing a conventional steel pipe loop construction method.

먼저 조립되지 않은 강관(161a)과 강관조립체(161b)를 추진기지(도시되지 않음)로부터 도달기지(도시되지 않음)로 압입시키는 작업을 반복하여 강관루프(161)의 수평구간을 형성한다(도41 및 도42 참조). 여기서 압입작업은 강관(161a)과 강관조립체(161b)의 추진 작업과 전방영역 굴착작업을 반복하는 방법으로 이루어진다.The operation of pressing the unassembled steel pipe 161a and the steel pipe assembly 161b from the propulsion base (not shown) to the arrival base (not shown) is repeated to form the horizontal section of the steel pipe loop 161 41 and Fig. 42). Here, the press-fitting operation is performed by repeating the propulsion operation of the steel pipe 161a and the steel pipe assembly 161b and the front area excavation operation.

다음에 강관루프(161)의 수평구간을 형성하는 방법과 동일하게 강관루프(161)의 수직구간을 형성한다(도42 참조).Next, a vertical section of the steel pipe loop 161 is formed in the same manner as the method of forming the horizontal section of the steel pipe loop 161 (see FIG. 42).

강관루프(161)의 형성이 완료되면 강관(161a)과 강관조립체(161b)의 내부에 철근을 조립한 후, 콘크리트나 모르타르을 주입하여 응고시킨다(도42 참조).After formation of the steel pipe loop 161 is completed, reinforcing bars are assembled into the steel pipe 161a and the steel pipe assembly 161b, and then concrete or mortar is injected and solidified (see FIG. 42).

다음에 강관루프(161)에 둘러싸인 공간을 굴착한다.Next, a space surrounded by the steel pipe loop 161 is excavated.

다음에 굴착공간에 콘크리트타설공법을 적용하여 콘크리트지하구조물(208)을 형성한다(도42 참조). 도42에 도시된 도면번호 161a는 구조물천정부를 나타내고, 도면번호 161b는 구조물좌측벽부를 나타내며, 도면번호 161c는 구조물우측벽부를 나타낸다.Next, a concrete pouring method is applied to the excavation space to form a concrete underground structure 208 (see FIG. 42). Reference numeral 161a shown in FIG. 42 represents a structure ceiling portion, reference numeral 161b represents a structure left side wall portion, and reference numeral 161c represents a structure right side wall portion.

전술한 구성을 갖는 강관루프공법은 2009년 특허출원 제1741호(발명의 명칭 : 강관조립체)에 개시되어 있다.The steel pipe loop construction method having the above-described construction is disclosed in 2009 Patent Application No. 1741 (entitled " Steel pipe assembly ").

그런데 종래의 강관루프공법의 콘크리트지하구조물 구축방법에 따르면, 콘크리트지하구조물(208)을 형성하기 위해 강관루프(161)를 형성하여야 하기 때문에 콘크리트지하구조물을 구축하는 절차가 복잡하다는 문제점이 있었다.However, according to the method of constructing the concrete underground structure of the conventional steel pipe loop method, since the steel pipe loop 161 must be formed to form the concrete underground structure 208, there is a problem that the procedure for constructing the concrete underground structure is complicated.

그리고 강관루프(161)에 둘러싸인 공간을 굴착하는 작업과 콘크리트타설공법작업이 완전히 분리되어 있어 콘크리트지하구조물을 구축하는 설비가 복잡해진다는 문제점이 있었다. Also, the work of excavating the space surrounded by the steel pipe loop 161 and the concrete pouring work are completely separated, complicating the construction of the concrete underground structure.

종래기술의 문제점을 해결하기 위해 안출된 본 발명의 목적은, 굴착추진장치의 하중지지부 외측을 원형관 형태의 외력지지관으로 감싸도록 배치시킴으로써, 기존의 빔부재를 사용하던 방식에 비해 형태를 자유롭게 제작할 수 있고, 구조적 안정성 및 큰 하중을 견딜 수 있는 지지력이 확보되도록 하는 세그멘트식 콘크리트지하구조물 구축용 굴착추진장치를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art by arranging the outer side of the load support portion of the excavation propulsion device so as to surround the outer side support tube in the form of a circular tube, The present invention provides a drilling propulsion device for constructing a concrete type underground structure of a concrete structure, which is capable of being manufactured and capable of securing a structural stability and a bearing capacity capable of withstanding a large load.
