Description

해체를 용이하게 하는 작업구용 강관의 구조{Structure of steel pipe for work area to facilitate dismantling}Structure of steel pipe for work area to facilitate dismantling}

본 발명은 해체를 용이하게 하는 작업구용 강관의 구조에 관한 것으로, 더욱 상세하게는 도시 기반 시설 확충을 위해 실드(Shield) 및 세미실드(Semi-shield)공법에 의해 지하터널이나 하수구를 구축할 때 굴착기계를 설치하고 굴진시 발생하는 토사와 암반을 지상으로 배출시키는 통로 역할을 하는 수직의 작업구를 구축하는 강관을 터널공사 완료 후 취출이 용이하도록 분할 결합하여 강관을 보다 쉽게 취출할 수 있도록 한 해체를 용이하게 하는 작업구용 강관의 구조에 관한 것이다. The present invention relates to a structure of a steel pipe for a work tool that facilitates dismantling, and more specifically, when constructing an underground tunnel or sewer by a shield and a semi-shield method for expanding an urban infrastructure. After installing the excavation machinery and dividing and joining the steel pipes that build up a vertical work tool that serves as a passage to discharge the soil and rock generated during excavation to the ground, it is easy to take out the steel pipes by dividing and combining them for easy extraction after the tunnel construction is completed. It relates to the structure of a steel pipe for work tools that facilitates dismantling.

일반적으로 작업구(수직구)는 터널이나 하수구 등을 굴착하기 위하여 지상으로부터 지하 터널까지 수직으로 연결해주는 일종의 수직터널로서 터널 공사 시에는 각종 장비 및 건설 자재들을 지상으로부터 운반 및 이동시키고, 터널 굴진 시에 발생되는 토사와 암반을 지상으로 배출시키는 통로 역할을 하며, 터널이 완성된 후에는 관리자의 이동통로 및 통신구나 전력구의 각종 케이블을 지하 터널로부터 지상으로 연결시켜 주고, 점검과 수리등을 하기 위해 출입하는 맨홀로서 사용하게 된다.In general, a work tool (vertical tool) is a kind of vertical tunnel that vertically connects from the ground to the underground tunnel to excavate a tunnel or sewer, etc. During tunnel construction, various equipment and construction materials are transported and moved from the ground. It acts as a passage for discharging soil and rock generated in the ground to the ground, and after the tunnel is completed, connect various cables of the manager's mobile passages, communication channels, and electric power tools from the underground tunnel to the ground, and perform inspections and repairs. It is used as a manhole to enter and exit.

실드 및 세미실드 공법은 지하터널을 굴착을 위하여 굴착기계를 목표로 하는 지하심도에 기계를 설치한 후 목표로 하는 터널 경로를 따라 기계가 수평으로 굴착을 하게 되는 데, 이때 굴착기계를 지하의 일정한 심도에 설치하기 위한 작업구를 굴착시에는 벽체가 붕괴하는 것을 방지하기 위하여 스트라트(Strut)공법, 라이닝(Lining)공법, JSP 지반개량공법, SEC 지하연속벽 공법 및 트랜치 커터(Trench Cutter)에 의한 지하연속벽 공법등의 벽체 가시설 공법이 적용되고 있다.In the shield and semi-shield method, the machine is horizontally excavated along the target tunnel path after the machine is installed at the underground depth targeting the excavation machine to excavate the underground tunnel. In order to prevent the wall from collapsing when excavating a work tool to be installed in the depth, the strut method, lining method, JSP ground improvement method, SEC underground continuous wall method and trench cutter are used. The construction method of temporary wall structures such as the underground continuous wall construction method has been applied.

그러나, 이와같은 공법들은 차수 및 가 시설 공사가 완료된 후에 지표로 부터 지하로 수직방향으로 설계 심도까지 지반을 굴착하고 지하에서 벽체 구조물을 시공하게 되는 과정을 거치는 공정상의 어려움이 있고 이로 인해 공기가 지연되고 공사비용이 증가하며 가시설 공사에 요구되는 대형장비로 인하여 교통 불편을 유발하고 소음이 많이 발생하게 되는 문제점이 있다.However, these construction methods have difficulty in the process of excavating the ground from the surface to the design depth in the vertical direction from the surface to the design depth after the completion of the construction of the order and provisional facilities, and the air is delayed due to the process of constructing a wall structure in the basement. In addition, there is a problem that the construction cost increases and the large equipment required for temporary facility construction causes traffic inconvenience and generates a lot of noise.

따라서, 협소한 도로지역, 주택 인접지역 등 지하 매설물이 많고 연약한 지반에서 종래와 같이 별도의 가시설 벽체를 시공하는 번거러움이 없이 주변지반의 교란과 지하수 유출에 따른 인접 지반의 침하를 방지하면서 안전하게 작업구를 형성하는 시공방법으로 강관작업구를 압입 시공하는 방법이 많이 사용되고 있다.Therefore, there are many underground buried areas such as narrow road areas and residential areas, and it is a safe work area while preventing the settlement of adjacent grounds due to the disturbance of surrounding grounds and the subsidence of groundwater without the hassle of constructing a separate temporary facility wall as in the prior art. As a construction method of forming a steel pipe, a method of press-fitting a steel pipe work tool has been widely used.

그러나, 터널 공사가 끝나면 하부에 사람이 출입할 수 있는 맨홀을 남겨두고 나머지는 되메우기하여 작업구를 막게 되는 데 이때에는 맨홀이 위치한 강관의 하부 일부를 제외하고 원주를 따라 절단하여 절단된 상부 강관을 인발기등으로 취출한 후 되메우기 작업을 하게 된다.However, at the end of the tunnel construction, a manhole that can be accessed by a person is left at the bottom, and the rest is backed up to block the work tool. At this time, except for the lower part of the steel pipe where the manhole is located, cut along the circumference to cut the upper steel pipe. After it is taken out with a drawer, it is backfilled.

이와같이 강관을 취출하기 위해 절단작업을 하게 되면 절단된 부위로 부터 지하수가 내부로 유입되는 경우가 허다하여 절단작업을 하기 전에 절단부의 외측 지중에 그라우팅재를 주입시켜 차수작업을 먼저 한 후 절단을 하게 되므로 그라우팅작업에 따른 작업상의 번거러움과 별도의 비용이 소요될 뿐 아니라 절단기로서 비교적 큰 직경으로서 두께를 가진 강관을 절단하는 시간도 많이 소요되며 공사기간이 길어지는 등 여러가지의 문제를 가지고 있었다. When the cutting work is performed to take out the steel pipe in this way, groundwater often flows into the interior from the cut part. Before the cutting work, the grouting material is injected into the outer ground of the cutting section to perform the watering work first before cutting. Therefore, it takes a lot of trouble, such as a hassle and a separate cost for the grouting operation, and also takes a lot of time to cut a steel pipe with a relatively large diameter as a cutter, and a longer construction period.

본 발명의 목적은 상기한 문제점을 해소하기 위한 것으로 강관을 취출관과 매설관으로 분할하되 분리 가능하도록 서로 연결하여 터널 작업이 끝난 후 취출할 때 종래와 같은 그라우팅 주입을 하지 않고 간단한 분리작업으로 취출관만을 취출할 수 있게 함으로써 강관 취출을 매우 효율적으로 편리하게 할 수 있는 해체를 용이하게 하는 작업구용 강관의 구조를 제공하는 데 있다. The object of the present invention is to solve the above problems, but the steel pipes are divided into a blowout pipe and a buried pipe, but connected to each other so that they can be separated.

The present invention is a means for achieving this purpose, in constructing a steel pipe for a work tool, the steel pipe is divided into a buried pipe which is buried in the ground after the tunnel operation and a withdrawal pipe that is taken out after the tunnel operation, and the total length connected thereto is It provides a structure of a steel pipe for a tool that facilitates dismantling, characterized in that it is made of a length corresponding to the planned depth of the tool and the buried pipe and the take-out pipe are integrally connected as a connecting device.

상기 연결장치는 매설관과 취출관의 연결단부의 내측에 대칭되게 단입시킨 ㄱ 자 형상의 단입부와, 상기 단입부에 끼워져 연결단부 사이의 간격을 수밀되게 차단하는 고무판과, 상기 고무판의 외면에 밀착되어 각 연결단부에 볼트로서 각각 고정되는 두개의 철판과, 취출관과 매설관의 연결단부 내측에서 취출관과 매설관을 일체로 연결되게 용착하는 다수개의 ㄷ 자 형상의 연결구로 이루어짐을 특징으로 한다. The connecting device is provided with an a-shaped cut-out part symmetrically inserted into the inside of the connecting end part of the buried pipe and the blow-out tube, a rubber plate fitted to the cut-in part to tightly block the gap between the connected ends, and an outer surface of the rubber plate. It is made of two iron plates that are tightly fixed to each connection end as bolts, and a plurality of U-shaped connectors that weld and connect the extraction pipe and the buried pipe integrally inside the connection end of the extraction pipe and the buried pipe. do.

이와 같이 본 발명은 작업구를 구성하는 강관을 원주를 따라 강관을 분할 절단하는 작업이나 그라우팅 작업을 할 필요없이 간단한 몇개의 연결간 만을 절단하는 작업으로 강관을 쉽게 분할할 수 있으므로 강관의 취출작업을 매우 효율적으로 할 수 있고 원주를 따라 강관 전체를 절단하는 작업이 필요하지 않아 오랜 시간의 절단작업에 따른 각종 폐해를 감소시킬 뿐아니라 작업시간이 단축되어 공기를 단축할 수 있으며 절단작업과 그라우팅작업에 따른 비용을 대폭 절감하여 경제적인 효과를 제공하는 점에서 매우 유용한 발명이다. In this way, the present invention can easily divide the steel pipe by dividing and cutting the steel pipe constituting the work tool along the circumference, or by cutting only a few simple connections without having to perform a grouting operation. It can be very efficient and does not need to cut the entire steel pipe along the circumference, so it not only reduces the damage caused by long-time cutting work, but also shortens the working time and shortens the air. It is a very useful invention in that it provides economical effects by significantly reducing the cost.

도 1 내지 도 6에 도시된 바와 같이 본 발명은 작업구용 강관(100)을 구성함에 있어서, 상기 강관(100)은 터널 작업후 지중에 매설되는 매설관(10)과 터널 작업후 취출되는 취출관(20)으로 분할 구성되어 이를 연결한 전체 길이가 작업구의 계획심도에 대응하는 길이로 이루어지고 상기 매설관(10)과 취출관(20)은 연결장치(30)로서 일체가 되게 연결되어 이루어짐을 특징으로 한다. 1 to 6, the present invention is to construct a steel pipe 100 for a work tool, the steel pipe 100 is a buried pipe 10 buried in the ground after the tunnel work and a take-out pipe taken out after the tunnel work It is divided into (20) and the entire length connected to it is made of a length corresponding to the planned depth of the work tool, and the buried pipe 10 and the extraction pipe 20 are integrally connected as a connecting device 30. It is characterized by.

상기 연결장치(30)는 매설관(10)과 취출관(20)의 연결단부(10')(20')의 내측에 대칭되게 단입시킨 ㄱ 자 형상의 단입부(11)(21)와, 상기 단입부(11)(21)에 끼워져 연결단부(10')(20') 사이의 간격을 수밀되게 차단하는 고무판(40)과, 상기 고무판(40)의 외면에 밀착되어 각 연결단부(10')(20')에 볼트(50)(50')로서 각각 고정되는 두개의 철판(60)(60')과, 취출관(20)과 매설관(10)의 연결단부(10')(20') 내측에서 취출관(20)과 매설관(10)을 일체로 연결되게 용착하는 다수개의 ㄷ 자 형상의 연결구(70)(70')로 이루어져 있다.The connecting device 30 is a buried pipe 10 and the extraction end of the connection end (10') (20') of the extraction pipe 20 symmetrically inserted into the a-shaped cut-out portion 11, 21, The rubber plate 40 is fitted to the indentation portions 11 and 21 to tightly block the gap between the connection end portions 10' and 20', and each connection end portion 10 is in close contact with the outer surface of the rubber plate 40 Two iron plates 60 and 60', which are each fixed as bolts 50 and 50' to the '20', and a connecting end 10' of the take-out pipe 20 and the buried pipe 10 ( 20') It consists of a plurality of U-shaped connectors 70 and 70' that are welded so as to be integrally connected to the extraction pipe 20 and the buried pipe 10 from the inside.

도면 중 미설명 부호 80은 맨홀이고, 81은 맨홀(80)과 연결 설치하는 사다리관이다. In the drawing, reference numeral 80 is a manhole, and 81 is a ladder tube connected to the manhole 80.

이와같이 된 본 발명은 작업구를 형성하는 강관(100)을 종래와 같이 한 개의 관체로 구성하지 않고 분할 구성하여 연결장치(30)에 의거 연결함으로써 터널 완성후 연결장치(30)만을 제거하면 매설관(10)과 취출관(20)이 간단히 분리되어 취출관(20)의 취출을 용이하게 할 수 있게 한 데 특징이 있는 것으로 연결장치(30)에 의거 연결된 강관(100)의 전체 길이는 계획심도에 대응하는 길이로 이루어지게 되는 데 이같이 취출관(20)과 매설관(10)으로 분할 구성된 강관(100)을 연결하는 연결장치(30)는 매설관(10)과 취출관(20)의 연결단부(10')(20')의 내측에 ㄱ 자 형상으로 대칭되게 형성한 단입부(11)(21)와 상기 단입부(11)(21)에 끼워져 수밀을 유지하는 고무판(40)과 상기 고무판(40)의 외면에 밀착되어 각 연결단부(10')(20')에 볼트(50)(50')로서 각각 고정되는 두개의 철판(60)(60')과, 취출관(20)과 매설관(10)의 연결단부(10')(20') 내측에서 취출관(20)과 매설관(10)을 일체로 연결되게 용착하는 다수개의 ㄷ 자 형상의 연결구(70)(70')로 이루어져 수밀유지와 함께 작업구를 형성하기 위해 지중으로 압입시 서로를 강건하게 연결하는 목적을 달성하게 된다. In this way, the present invention is formed by dividing the steel pipe 100 forming a work tool into a connecting device 30 by dividing the structure into a single tube body, and removing the connecting device 30 only after the completion of the tunnel. (10) and the extraction pipe (20) is simply separated, characterized in that to facilitate the extraction of the extraction pipe (20), the overall length of the steel pipe (100) connected by the connecting device (30) is planned depth The connecting device 30 for connecting the steel pipe 100, which is divided into the extraction pipe 20 and the buried pipe 10, is made to have a length corresponding to the connection between the buried pipe 10 and the extraction pipe 20. The end portions 10' and 20' have a rubber plate 40 that is inserted into the cutouts 11 and 21 and the cutouts 11 and 21 symmetrically formed in the shape of a letter A and the Two iron plates (60) (60'), which are in close contact with the outer surface of the rubber plate (40) and fixed to each connection end portion (10') (20') as bolts (50) (50'), and the extraction pipe (20). And a plurality of U-shaped connectors 70 and 70' for welding the connection pipes 10 and the buried pipe 10 to be integrally connected from the inside of the connection ends 10' and 20' of the buried pipe 10 ) To achieve the purpose of firmly connecting each other when press-fitting into the ground to form a work tool together with maintaining watertightness.

상기한 연결장치(30)의 연결과정을 보다 구체적으로 설명하면, 매설관(10)과 취출관(20)을 연결단부(10')(20')의 내측에 형성된 ㄱ 자 형상의 단입부(11)(21)가 마주보도록 연결하게 되면 ㄱ 자 형상의 단입부(11)(21)는 두개의 단입부(11)(21)가 합쳐져 ㄷ 자 형상의 복합단입부를 형성하므로 이에 비교적 두꺼운 고무판(40)을 끼워 넣고 그 외면에 두개의 분할된 철판(60)(60')을 밀착시켜 각각의 철판(60)(60')을 볼트(50)(50')로서 매설관(10)과 취출관(20)에 각각 나사 고정하게 되면 매설관(10)과 취출관(20)은 고무판(40)에 의해 사이 간격이 수밀되는 상태로 연결되며 이 상태에서 ㄷ 자 형상의 연결구(70)(70')로서 매설관(10)과 취출관(20)을 용착하게 되면 두개의 분할된 관체는 일체로 연결되어 작업구의 계획심도에 대응하는 길이의 단일체의 강관(100)을 형성하게 된다. The connection process of the above-described connection device 30 will be described in more detail. The buried pipe 10 and the extraction pipe 20 are formed with an a-shaped indentation formed inside the connection ends 10' and 20'. 11) When the 21 is connected so as to face each other, the a-shaped cut-out portions 11 and 21 are formed by combining the two cut-out portions 11 and 21 to form the c-shaped composite cut-out portion, thereby making the relatively thick rubber plate ( 40) by inserting the two divided iron plates (60, 60') in close contact with the outer surface, and each iron plate (60) (60') as a bolt (50) (50') is taken out with the buried pipe (10) When the screws are fixed to the pipes 20, the buried pipes 10 and the extraction pipes 20 are connected in a state in which the gap is tightly sealed by a rubber plate 40. In this state, the U-shaped connectors 70 and 70 ') When the buried pipe 10 and the extraction pipe 20 are welded, the two divided pipes are integrally connected to form a single-piece steel pipe 100 having a length corresponding to the planned depth of the work tool.

따라서, 종래의 단일체로 된 강관(100)과 같이 지중에 압입하여 작업구를 형성하게 되고 분할된 매설관(10)과 취출관(20)의 사이 간격은 단입부(11)(21)에 끼워져 두개의 철판(60)(60')으로 밀착 고정된 고무판(40)에 의거 외부의 물이 내부로 유입되지 않도록 차단되는 데 고무판(40)의 외면에는 철판(60)(60')이 밀착되어 볼트(50)(50')로서 나사 고정되어 있으므로 고무판(40)을 강관(100)을 지중에 압입시 토사가 침투하거나 토사에 의해 파손되지 못하도록 보호되어 밀착력이 감소되는 것을 방지하게 된다. Therefore, as in the conventional monolithic steel pipe 100, it is press-fitted into the ground to form a work tool, and the gap between the divided buried pipe 10 and the blow-out pipe 20 is sandwiched between the cut-in portions 11 and 21. On the outer surface of the rubber plate 40, the iron plate 60 (60') is in close contact with the outer side of the rubber plate 40. As the bolts 50 and 50' are screwed, the rubber plate 40 is protected from being penetrated by the soil or damaged by the soil when the steel pipe 100 is pressed into the ground to prevent the adhesion from being reduced.

이러한 고무판(40)은 취출관(20)과 매설관(10)의 틈새를 차단하는 역할을 하므로 볼트(50)(50')로서 가압시 압착되는 것을 감안하여 비교적 두꺼운 두께를 가지며 내구성이 우수한 소재로 이루어진다. Since the rubber plate 40 serves to block the gap between the extraction pipe 20 and the buried pipe 10, it has a relatively thick thickness and excellent durability in view of being compressed when pressed as a bolt 50, 50' Is made of

그리고 상기와 같이 고무판(40)으로 연결된 매설관(10)과 취출관(20)을 일체로 고정하는 연결구(70)(70')는 ㄷ 자 형상의 금속재로서 이루어져 매설관(10)과 취출관(20)을 단일체로 강건하게 연결하게 되는 데 첨부도면의 실시예와 같이 십자형상으로 4개 정도 용착하면 일체화 된 강관(100)을 형성하는 데 문제가 없으나 필요에 따라 가감하여 설치하게 된다.And the connecting pipe 70 and 70' integrally fixing the buried pipe 10 and the extracting pipe 20 connected by the rubber plate 40 as described above is made of a U-shaped metal material and the buried pipe 10 and the extracting pipe Although the 20 is firmly connected as a single body, there are no problems in forming the integrated steel pipe 100 when four are welded in a cross shape as in the embodiment of the accompanying drawings, but it is installed by adjusting as needed.

터널 작업 후 강관(100)을 해체할 때에는 연결장치(30)를 해체하여 매설관(10)은 지중에 매설된 상태에 두고 취출관(20)만을 지상으로 인발하여 취출하게 되는 데 이때에는 다수개 용착된 ㄷ 자 형상의 연결간을 용착한 용접비드를 불어내어 제거하거나 절단하게 되면 취출관(20)과 매설관(10)은 강도가 약한 고무판(40)으로만 연결된 상태이므로 인발기를 이용하여 취출관(20)을 요동하면서 인발하게 되면 고무판(40)은 쉽게 찢어지게 되는 데 이때 고무판(40)은 도 5에 도시된 바와 같이 외면에 밀착 고정한 두개의 철판(60)(60') 사이가 찢어지게 되므로 취출관(20)과 매설관(10)의 연결구조가 해체되어 취출관(20)만을 인발장치에 의해 지상으로 취출할 수 있게 되고 취출 후 작업구를 되메우기 하면 된다. When the steel pipe 100 is dismantled after the tunnel work, the connecting device 30 is dismantled so that the buried pipe 10 is buried in the ground, and only the pipe 20 is drawn to the ground to be taken out. When the welded bead welded between the connected U-shaped connections is blown out or removed, the take-out pipe 20 and the buried pipe 10 are connected only by a rubber plate 40 having a weak strength, and thus taken out using a drawer. When the tube 20 is pulled out while swinging, the rubber plate 40 is easily torn. At this time, the rubber plate 40 is torn between two iron plates 60 and 60' fixedly attached to the outer surface as shown in FIG. Since the connection structure between the take-out pipe 20 and the buried pipe 10 is disassembled, only the take-out pipe 20 can be taken out to the ground by a drawing device, and the work tool can be refilled after taking out.

작업구에 내에 첨부도면의 실시예와 같이 맨홀(80)이 설치될 때에는 맨홀(80)과 연결된 사다리관(81)을 지상으로 연결되게 설치한 상태에서 취출관(20)을 취출하고 되메우기를 시도하면 된다. When the manhole 80 is installed in the work tool as in the embodiment of the accompanying drawings, the ladder pipe 81 connected to the manhole 80 is installed to be connected to the ground, and then the take-out pipe 20 is removed and attempted to be refilled. You can do it.

이와같이 본 발명은 강관(100)을 단일체로 구성하지 않고 매설관(10)과 취출관(20)으로 분할하여 연결장치(30)에 의해 임시 연결한 상태로 지중에 매설되어 작업구를 형성하고 터널 작업이 완료된 후에는 연결장치(30)를 해체하여 취출관(20)만을 취출할 수 있게 한 것이므로 종래와 같이 원주를 따라 절단작업을 해야 하는 번거러움과 작업상의 어려움이 없고 특히 차수를 위한 그라우팅작업을 필요로 하지 않으므로 공사비의 절감과 공기를 단축할 수 있는 등 그 효과가 매우 크다.As described above, the present invention does not constitute the steel pipe 100 as a single body, but is divided into a buried pipe 10 and a draw pipe 20 to be temporarily connected by a connecting device 30 to be buried in the ground to form a work tool and tunnel. After the work is completed, the connection device 30 is disassembled so that only the extraction pipe 20 can be taken out, so there is no trouble and trouble in working along the circumference as in the prior art, and especially grouting for order Since it is not required, the effect is very large, such as reducing construction costs and shortening the air.
