Description

비개착의 지하에 굴착용 구조물을 축조하는 방법{Process for constructing a structure for excavation in underground}Process for constructing a structure for excavation in underground

본 발명은 비개착의 지하에 굴착용 구조물을 축조하는 방법에 관한 것으로서, 특히 대구경관을 이용하여 비개착의 지하에 굴착용 구조물을 축조함에 있어서 대구경관 속에 링형 빔(Ring Beam)을 등간격으로 먼저 설치한 후 굴착용 구조물을 축조하는 방법에 관한 것이다.The present invention relates to a method for constructing an excavation structure in an unattached basement. In particular, in constructing an excavation structure in an unattached basement using a large diameter tube, a ring beam is uniformly spaced in the large diameter tube. It first relates to a method of constructing an excavation structure after installation.

종래에는 비개착의 지하에 굴착용 구조물을 축조함에 있어서, 도4에 도시된 바와같이, 다수개의 대구경관(튜브)(1)을 땅속에 관의 내부(중공부)가 보이도록 나란히 설치하되 그 설치된 관의 다수개의 단면(중공부)들이 모여 소정의 굴착용 구조물 형태의 원형이나 각형을 이루도록 설치한 후 상기 대구경관의 측면들을 절개하여 절개부(30)(30')를 형성한 다음 그 인접한 관들의 절개부(30)(30')끼리 금속판(40)으로 연결되도록 용접한 후, 상기 인접한 대구경관(1)들 사이의 상면에 벽돌이나 소구경관(20)을 얹어 놓은 후 그라우팅부(20')를 형성하여 다수개의 관들을 고정시키는 방법으로 구조물을 축조하였었다.Conventionally, in constructing an excavation structure in an unattached basement, as shown in Figure 4, a plurality of large diameter tube (tube) (1) is installed side by side so that the inside (hollow part) of the tube in the ground, A plurality of end faces (hollow parts) of the installed tube are gathered and installed to form a circular or rectangular shape of a predetermined excavation structure, and then the sides of the large diameter tube are cut to form cutouts 30 and 30 'and then adjacent After welding the incisions 30, 30 ′ of the pipes to be connected to the metal plate 40, the brick or small-diameter pipe 20 is placed on the upper surface between the adjacent large-diameter pipes 1 and then the grouting part 20. ') Was used to build the structure by fixing multiple tubes.

그러나 상기와 같은 지하 굴착을 위한 구조물 축조방법에 있어서는 인접한 대구경관의 측면을 절개하여 그 절개부위끼리 연결되도록 금속판(40)으로 용접하거나 그 인접한 대구경관(1)사이를 그라우팅하게되면 대구경관이 절개부위에 의하여 주저 앉거나 찌그러지거나 일그러지게되고 절개부가 없더라도 그라우팅 및 용접시에 관이 변형되어 작업이 불가능하거나 어렵게 되는 결점이 있었다.However, in the method of constructing a structure for underground excavation as described above, when the side surface of the adjacent large diameter tube is cut and welded with the metal plate 40 or grouted between the adjacent large diameter tube 1 so that the incisions are connected, the large diameter tube is cut. Even if the site is hesitant, squashed or distorted by the site and there is no incision, the tube is deformed during grouting and welding, which makes the operation impossible or difficult.

본 발명은 상기한 바와같은 비개착의 지하에 굴착용 구조물을 축조함에 있어서의 결점을 개선하여 대구경관의 원형을 완벽하게 유지하면서 그라우팅이나 절개 및 그 절개부끼리의 연결 용접이 원활하게 이루어지도록한 비개착의 지하에 굴착용 구조물을 축조하는 방법을 제공코저하는 것으로서 이를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.The present invention is to improve the defects in the construction of the excavation structure in the basement of the non-adhesive base as described above, so that the grouting or incision and the connection welding between the incisions are smoothly maintained while maintaining the circular shape of the large diameter. The present invention provides a method of constructing an excavation structure in an unattached basement, which will be described in detail with reference to the accompanying drawings.

Then, the side of each large diameter tube 1 is cut to form cutouts 30 and 30 ', and then the cutouts 30 and 30' are welded to the metal plate 40 and then adjacent to the cod. In the method of constructing the excavation structure in the basement by forming a grouting portion 20 'on the small pipe or brick 20 between the landscape (1), H-beam (Beam) or I separately A plurality of arc-shaped pieces (3) of the shape beam are connected by welding or by connecting parts (4) by bolts and nuts to form a cylindrical ring beam (2), and the outer diameter of the ring beam (2) is the large diameter tube (1). After obtaining a cylindrical ring beam (2) formed so as to match the inner diameter of The cylindrical ring beam 2 obtained above is inscribed at equal intervals inside the large-diameter tube 1 just before performing the process of welding the cutouts 30 and 30 'to the metal plate 40 during the molding construction process. After the welding installation, the process of welding the metal plate 40 between the cut portions 30 and 30 'and the grouting portion 20' containing the small pipe or the brick 20 are performed. In constructing a non-adherent deeply excavated structure by the above-described method, first, a plurality of large-diameter pipes (1) by the conventional method to each other so that the interior (hollow portion; end of the pipe) is visible. Arranged side by side, the arranged pipes are arranged so as to form a predetermined excavation structure of a cylindrical or angular shape, and then incisions on the side of the adjacent large-diameter tube 1 during the existing commercial excavation structure construction process ( 30) 30 'to form the incision Immediately before connecting to the plate 40, a plurality of arc-shaped pieces 3 of H-shaped or I-shaped beams are separately connected by welding or by connecting portions 4 by bolts and nuts. After the ring beam 2 having the same outer diameter as the inner diameter is welded to the inside of the arrayed large-diameter tube 1 at equal intervals, the cut beam is then cut to the side of the adjacent large-diameter tube 1, which is a commonly used process. 30) (30 ') to form a grouting portion (20') by forming a small pipe or brick 20 between the large diameter pipe (1) by connecting the incision to the metal plate 40 by welding By doing so, the large diameter tube 1 is not uniformly deformed or deformed, and thus, a uniform construction process is made.

이상과 같은 방법으로 지하 굴착용 대구경관(1)내에 링빔을 내접 설치한 다음 기타 통상의 방법으로 굴착용 구조물을 축조하므로서 대구경관이 그라우팅이나 용접시에 일그러지거나 찌그러지지 않고 원형을 유지하면서 완전하고 완벽한 시공을 할 수 있는 장점과 효과가 있는 것이다.In the same way as above, the ring beam is internally installed in the large-diameter pipe for underground excavation, and then the excavating structure is constructed by other conventional methods. There is an advantage and effect to perfect construction.
