Description
본 발명은 통신용 관로 건설에 적합한 비개착 중구경 관로 건설공법에 관한 것으로, 더욱 상세하게는 다수의 맨홀 사이 전 구간을 한 개의 발진구와 도달구를 축좌여 중압잭과 굴착기를 이용하여 한번에 굴착한 뒤 맨홀이 필요한 위치에 지상으로부터 거꾸로 터파기 하여 맨홀을 설치하는 비개착 중구경 관로 건설공법에 관한 것이다.The present invention relates to a non-adhesive medium-diameter pipeline construction method suitable for construction of communication pipelines, and more specifically, after excavating at a time by using a heavy jack and excavator with one oscillation port and an reaching port in the entire section between a plurality of manholes. The present invention relates to an unattached medium-diameter pipeline construction method in which a manhole is installed by digging upside down from the ground where a manhole is needed.
일반적으로 통신 케이블을 매설하기 위해서는 굴착공사를 통해 통신용 관로를 매설하고, 관로를 통해 통신 케이블을 포설한다. 한편, 관로의 중간 중간에는 맨홀을 설치하여 통신 케이블을 접속하거나 분기시키는 작업을 할 수 있는 공간이 마련된다.In general, in order to bury the communication cable is buried communication pipeline through the excavation work, and the communication cable is laid through the pipeline. On the other hand, in the middle of the pipeline is provided a space for installing the manhole to connect or branch the communication cable.
그러나, 교통량이 많은 도심에서 땅을 개착하여 여러 가지 관로 공사를 하는 것은 장기간의 교통소통 장애로 주민의 불편이 따른다. 또한, 도심지 지하에는 여러 가지 지하 시설물들이 거의 포화상태로 존재하므로 땅을 파는 것은 매우 힘들고 위험을 수반한다.However, the construction of various pipelines on the ground in urban areas with heavy traffic brings inconveniences to residents due to long-term traffic disturbances. In addition, digging underground is very difficult and risky because many underground facilities are almost saturated.
최근에는 땅을 파지 않고 지하에 관로를 매설하는 비개착 관로 건설 공법이 많이 개발되어 있다. 이 공법은 특수한 관을 사용하여 발진구로부터 도달구까지 기계장비로 땅을 굴삭하면서 관을 유압잭으로 밀어 넣어 일정한 구간의 관로를 건설하는 공법이다. 이 공법을 사용하면 시작점에 해당하는 발진구와 끝점에 해당하는 도달구에만 굴착공사를 하면 되므로 도심지의 교통 소통 방해를 최소화할 수 있다.In recent years, many non-open pipeline construction methods have been developed that bury underground pipelines without digging. This method uses a special pipe to excavate the ground with mechanical equipment from the oscillation opening to the reaching opening, and pushes the pipe into the hydraulic jack to build a certain section of pipeline. Using this method, the excavation work only needs to be performed at the start point corresponding to the starting point and the arrival point corresponding to the end point, thereby minimizing the disturbance of traffic in urban areas.
매설되는 관로의 구경에 따라 대구경, 중소구경으로 크게 나눌 수 있는데 특히, 터널보다는 규모가 작은 중소구경(1000mm)이하의 비개착 관로 건설 공법으로 세미실드 공법이 주로 이용된다. 이 방법은 목표한 심도만큼 발진구와 도달구를 굴착하고 발진구에 일정한 길이로 제작된 관을 압입하는 역할을 하는 유압잭과 관의 최선두에서 지반을 굴착할 굴착기를 설치하여 도달구를 향하여 굴진작업을 시작한다. 굴착기가 적당한 길이만큼 굴진하면 일정한 길이의 관을 계속 잇대어 압입한다. 이러한 작업을 계속하면 굴착기가 먼저 도달구에 도달되어 회수되고 계속 잇대어진 관이 결국에는 발진구와 도달구를 연결하는 관로를 형성하게 되고 도달구와 발진구는 추가 발진을 위해 사용되든지 아니면 관로를 연결하는 맨홀이 설치되고 매립된다. 이와 같은 일련의 공정은 전형적인 세미실드 비개착 공법이다. 이 공법의 발진구와 도달구에는 유압잭의 압력을 견딜 수 있고 지반의 갑작스런 함몰을 방지하기 위한 지반개량을 해야 하므로 축조 비용이 비싸다. 그러므로 발진구와 도달구가 길수록 다시말해서 한번의 굴착기 설치로 굴착할 수 있는 구간이 길수록 경제적이다.Depending on the size of the buried pipeline, it can be largely divided into large diameter and small and medium diameter. In particular, semi-shield method is mainly used for the construction of the non-opening pipeline of less than 1000mm, which is smaller than the tunnel. In this method, excavation work is carried out toward the reach by installing the hydraulic jack that excavates the oscillation port and the reach port as the target depth and presses the tube made of a certain length into the oscillation port, and the excavator that excavates the ground at the head of the pipe. To start. When the excavator is drilling the proper length, it continues to press in a tube of constant length. If this operation is continued, the excavator first reaches the outlet and is recovered, and the continuous pipes eventually form a conduit connecting the oscillator to the conduit, which is used for further oscillation or the manhole connecting the conduit. It is installed and reclaimed. This series of processes is a typical semishield unbonded process. Since the oscillation port and the arrival port of this method can withstand the pressure of the hydraulic jack and the ground must be improved to prevent the sudden depression of the ground, the construction cost is high. Therefore, the longer the oscillation port and the reaching port, that is, the longer the interval that can be excavated with one excavator installation, the more economical it is.
도 1은 종래의 비개착 관로 건설공법으로 대표적인 세미실드 공법을 도시한 공정 개략도이다.1 is a process schematic diagram showing a typical semi-shielded method as a conventional non-adhesive pipe construction method.
도 1에 도시된 바와 같이, 1단계로 발진구(1) 및 도달구(2) 개착 및 가시설을 설치하고, 2 단계로 지반함몰 방지를 위한 지반 안정화 처리를 한다. 3단계로, 발진구(1)에 유압잭(3), 굴착기(4) 및 굴착장비를 설치하고, 4단계로 유압잭(3)과 굴착기(4) 사이에 관(5)을 설치하고 굴진을 시작한다. 5단계로 굴진작업이 완료되면 발진구(1) 및 도달구(2)에서 장비를 회수한다. 6단계로, 도달구(2)를 발진구(1)로 하여 1단계부터 5단계를 반복하여 관로(5)를 연장시켜 간다. 7단계로 도달구(2) 및 발진구(1)에 맨홀을 축조하여 관로 건설 공정을 완료한다.As shown in Figure 1, in one step, the oscillation opening (1) and the arrival opening (2) is attached to the installation and provisional facilities, and the ground stabilization treatment to prevent ground depression in two steps. In the third step, the hydraulic jack 3, the excavator 4 and the excavation equipment are installed in the oscillation port 1, and in the fourth step, the pipe 5 is installed between the hydraulic jack 3 and the excavator 4 and the excavation starts. do. When the excavation work is completed in step 5, the equipment is recovered from the oscillation opening (1) and the reaching opening (2). In step 6, the pipe 5 is extended by repeating step 1 to step 5 using the arrival port 2 as the oscillation port 1. In step 7, a manhole is constructed in the arrival opening 2 and the oscillation opening 1 to complete the pipeline construction process.
한편, 유압잭(3)과 굴착기(4)의 성능에는 한계가 있고 일정한 구간에 맨홀(6)을 설치할 필요가 있으므로 실제로 한 구간의 길이는 100m이하인 경우가 많다. 물론 압입되는 관의 중간 중간에 유압잭(3)을 설치하여 복수개의 유압잭(3)으로 관(5)을 압입하면 한구간의 길이는 훨씬 늘어날 수 있지만 일반적으로 1000mm이하 구경의 관로(5)에서는 굴진을 완료한 뒤 작업자의 출입이 불가능하여 관(5) 사이에 설치한 유압잭(3)을 회수할 방법이 없으므로 사용하기 곤란하다. 이러한 실정으로 인해 도심지일수록 비개착으로 통신관로를 설치할 필요성이 높지만 이에 반하여 도심지이기 때문에 케이블의 분기를 위한 맨홀의 설치구간이 조밀하여야 하므로 비개착공법을 적용하기에는 비효율적인 측면이 많았다.On the other hand, the performance of the hydraulic jack 3 and the excavator 4 has a limit and it is necessary to install the manhole 6 in a certain section, in fact, the length of one section is often 100m or less. Of course, if the hydraulic jack 3 is installed in the middle of the press-fitted pipe and the pipe 5 is pushed in with the plurality of hydraulic jacks 3, the length of one section can be much longer, but in general, the excavation is not performed in the pipe 5 having a diameter of 1000 mm or less. It is difficult to use because there is no way to recover the hydraulic jack (3) installed between the pipes (5) because the operator can not go out after completion. Due to this situation, the urban area is more necessity to install the communication channel in the non-attachment, but on the other hand, because the downtown area is mandatory installation section of the manhole for the branch of the cable was inefficient to apply the non-opening method.
즉, 종래의 비개착 건설 공법은 발진구(1)와 도달구(2)의 사이가 너무 가까우면 교통 장애 방지 효과가 적고 경제적으로 비효율적이다. 특히, 통신관로와 같이 번잡한 대도심에서 통신회선의 분기가 많이 필요할 경우 수십미터마다 맨홀을 설치하여야 하므로 발진구(1)와 도달구(2)에만 맨홀 설치가 가능한 기존 공법으로는 짧은 구간에 많은 발진구(1)와 도달구(2)가 설치되어야 하므로 비개착의 장점이 반감되고 또한, 발진구(1)와 도달구(2) 설치 비용이 매우 비싸고 굴착장비를 빈번하게 설치, 회수해야 하므로 경제성이 매우 떨어진다.That is, the conventional non-clamping construction method is less effective in preventing traffic obstacles and economically inefficient when the oscillation opening 1 and the arrival opening 2 are too close. In particular, if a large number of branch lines of communication lines are required in a busy city such as a communication pipeline, manholes should be installed every few tens of meters. Therefore, the manhole can be installed only in the oscillation opening (1) and the reaching opening (2). Since many oscillation openings (1) and reaching openings (2) must be installed, the advantages of non-separation are halved, and the installation cost of the oscillation opening (1) and reaching openings (2) is very expensive, and the excavation equipment must be frequently installed and recovered. Therefore, the economy is very poor.
따라서 본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로, 한번에 굴진할 수 있는 구간 길이는 충분히 늘리면서도 중간 중간에 맨홀을 필요에 따라 설치할 수 있는 비개착 건설 공법을 제공하는데 그 목적이 있다.Therefore, the present invention is to solve such a conventional problem, the object of the present invention is to provide a non-stick construction method that can be installed as needed manhole in the middle while sufficiently increasing the length of the section can be excavated at one time.
이와 같은 목적을 실현하기 위한 본 발명은 비개착 중구경 관로 건설 공법에 있어서, 다수의 맨홀이 설치될 위치를 포함할 수 있도록 설정된 발진구와 도달구를 개착하여 가시설을 설치하는 제 1 단계와, 발진구와 도달구에 지반 함몰 방지를 위한 지반 안정화 처리를 하는 제 2 단계와, 발진구에 유압잭 및 굴착기를 설치하는제 3 단계와, 유압잭과 굴착기 사이에 관을 설치하고 굴진을 시작하는 제 4 단계와, 맨홀이 설치될 위치를 미리 설정하여 굴진되는 관 사이에 중압잭을 설치하여 최종적으로 맨홀이 설치될 위치에 중압잭이 위치하도록 하는 제 5 단계와, 굴진작업이 완료되면 발진구 및 도달구에서 장비를 회수하는 제 6단계와, 미리 설정된 맨홀 설치 위치를 개착하여 중압잭을 회수하는 제 7단계와, 중압잭을 회수한 위치와 발진구 및 도달구에 맨홀을 축조하는 제 8단계를 포함한다.In the non-impact medium-diameter pipeline construction method for realizing such an object, the present invention provides a first step of installing a temporary facility by attaching an oscillation opening and an reaching opening that are set to include a position where a plurality of manholes are to be installed, and oscillation.

도 2는 본 발명에 따른 비개착 중구경 관로 건설 공법을 개략적으로 도시한 공정도이다.Figure 2 is a process diagram schematically showing a non-impact medium diameter pipeline construction method according to the present invention.
도시된 바와 같이, 본 발명에 따른 비개착 중구경 관로 건설 공법은 제 1 단계로 기존처럼 맨홀과 맨홀 사이를 1구간으로 하여 발진구(1)와 도달구(2)를 축조하지 않고 최소한 몇 개의 맨홀들이 설치되는 구간을 1구간으로 하여 발진구(1)와 도달구(2)를 설치한다.As shown, the non-adhesive medium-diameter pipeline construction method according to the present invention is a first step between the manhole and the manhole as a first step in the first step without building the oscillation opening (1) and the reaching opening (2) at least a few The oscillation opening 1 and the reaching opening 2 are installed using the section in which the manholes are installed as one section.
제 2 단계로 발진구(1)와 도달구(2)에 종래와 마찬가지로 지반 함몰 방지를 위한 지반 안정화 처리를 한 후 제 3 단계로 발진구(1)에 일정한 길이로 제작된 관(5)을 압입하는 역할을 하는 유압잭(3)과 관의 최선두에서 지반을 굴착할굴착기(4)를 설치한다.(도 2b 참조)In the second step, the oscillation port 1 and the reaching port 2 are subjected to the ground stabilization treatment to prevent ground depression as in the prior art. Install a hydraulic jack (3) that serves to press-fit and an excavator (4) to excavate the ground at the head of the pipe (see Figure 2b).
이어서, 제 4 단계로 유압잭(3)과 굴착기(4) 사이에 관을 설치하고 도달구(2)를 향하여 굴진을 시작한다. 굴착기(4)가 적당한 길이만큼 굴진하면 일정한 길이의 관을 계속 잇대어 압입한다. 제 5 단계로 이러한 작업을 반복하여 굴진된 길이가 가장 마지막에 설치될 맨홀과 도달구(2) 사이의 길이(ℓ)와 동일한 지점의 관 사이에 중압잭(11)을 설치하고 굴진 작업을 계속한다. 따라서, 중압잭(11)은 굴착기(4)가 도달구(2)까지 도달하여 굴진 작업이 완료된 후에는 마지막 맨홀(10d)이 설치될 위치와 일치하게 된다.(도 2c 참조)Subsequently, in the fourth step, a pipe is installed between the hydraulic jack 3 and the excavator 4 and the excavation is started toward the arrival opening 2. When the excavator 4 excavates by a suitable length, it continues to press in a pipe of a certain length continuously. This operation is repeated in the fifth step to install the medium pressure jack 11 between the pipes at the point where the length of the excavated length is the same as the length (ℓ) between the manhole to be installed last and the access hole 2 and continue the excavation work. do. Therefore, the heavy pressure jack 11 coincides with the position where the last manhole 10d is to be installed after the excavator 4 reaches the arrival port 2 and the excavation work is completed (see FIG. 2C).
이와 같은 방법으로 도달구(2)로부터 설치 예정된 맨홀(10)까지의 거리를 역산하여 굴진 작업 중에 중압잭(11)을 설치함으로써 굴착 완료 후 중압잭(11) 위치를 맨홀(10d) 설치 위치와 일치시킨다. 이미 알려진 바와 같이, 다수의 중압잭(11)을 관(5) 사이에 설치함으로써 경간길이를 확대하는 것은 주지의 사실이다.By inverting the distance from the reach opening 2 to the manhole 10 to be installed in this manner, the heavy jack 11 is installed during the excavation work. Match. As is already known, it is well known to extend the span length by providing a plurality of medium pressure jacks 11 between the pipes 5.
제 6 단계로 굴진작업이 완료되면 발진구(1) 및 도달구(2)에서 유압잭(3) 및 굴착기(4) 등의 굴착장비를 회수한 후 제 7 단계로 미리 설정된 맨홀(10) 설치 위치를 개착한다.(도 2d 및 도 2e 참조) 이미, 맨홀(10) 설치 위치와 중압잭(11)의 위치가 일치된 상태이므로 맨홀(10) 설치 위치를 개착하면서 중압잭(11)을 회수하는 것이 가능하다.When the excavation work is completed in the sixth step, the excavation equipment such as the hydraulic jack 3 and the excavator 4 is recovered from the oscillation port 1 and the reaching port 2, and then the manhole 10 installation position preset in the seventh step (Refer to FIGS. 2D and 2E) Since the manhole 10 installation position and the position of the medium pressure jack 11 are in the same state, the medium pressure jack 11 is recovered while the manhole 10 installation position is attached. It is possible.
이어서, 제 7단계로 종래와 마찬가지로 중압잭을 회수한 위치와 발진구(1) 및 도달구(2)에 맨홀 구조물(12a,12b,12c,12d,12e)을 축조하여 관로 건설 공정을완료한다.(도 2f 참조)Subsequently, in the seventh step, the manhole structures 12a, 12b, 12c, 12d, and 12e are constructed at the position where the heavy jack is recovered and the oscillation port 1 and the arrival port 2, as in the prior art, to complete the pipeline construction process. (See Figure 2f)
이와 같은 본 발명에 따른 비개착 중구경 관로 건설 공법에 따르면 사람이 출입할 수 없는 중소구경의 비개착 관로(5) 건설시에도 중압잭(11)을 사용할 수 있으므로 하나의 발진구(1)와 도달구(2)를 이용하여 관로(5)를 건설할 수 있는 구간길이(경간길이)를 최대한 확장할 수 있다. 이는 발진구(1)와 도달구(2) 설치 개소를 줄일 수 있어 발진구(1)와 도달구(2)의 개착 비용 및 굴착장비 설치 및 회수 비용을 절감할 수 있다.According to the non-impact medium diameter pipeline construction method according to the present invention, since the medium pressure jack (11) can be used even in the construction of non-impact medium (5) of small and medium diameter, which can not enter and exit, one oscillation port (1) and It is possible to extend the section length (span length) that can be used to construct the pipeline 5 using the reach (2). This can reduce the installation location of the oscillation opening (1) and the reaching opening (2) can reduce the opening cost of the oscillation opening (1) and the reaching opening (2) and the installation and recovery costs of the drilling equipment.
또한, 본 발명에 따르면 맨홀 개착은 굴진작업 완료 후 중압잭(11)을 회수할 때 이루어지므로 맨홀 개착 기간을 최소화 할 수 있어 도심지에서의 교통 소통 방해 기간을 최소화 할 수 있다. 또한, 발진구(1)와 도달구(2) 사이에 포함된 맨홀 설치 위치들은 단지 맨홀만 축조될 뿐 기존처럼 발진구(1) 및 도달구(2)의 역할을 할 필요가 없으므로 개착해야 하는 규모면에서도 훨씬 작아져 비용 절감의 효과가 크다.In addition, according to the present invention, the manhole mounting is made when the heavy jack 11 is recovered after the excavation work is completed, so that the manhole opening period can be minimized, thereby minimizing the traffic communication period in the downtown area. In addition, the manhole installation positions included between the oscillation opening 1 and the reaching opening 2 need only be opened because only the manhole is constructed, and thus it does not need to serve as the oscillation opening 1 and the reaching opening 2 as before. It is much smaller in terms of size, resulting in significant cost savings.
이상, 상기 내용은 본 발명의 바람직한 일실시예를 단지 예시한 것으로 본 발명의 당업자는 본 발명의 요지를 변경시킴이 없이 본 발명에 대한 수정 및 변경을 가할 수 있음을 인지해야 한다.In the above description, it should be understood that those skilled in the art can only make modifications and changes to the present invention without changing the gist of the present invention as it merely illustrates a preferred embodiment of the present invention.
상술한 바와 같이 본 발명에 따르면, 사람이 출입할 수 있는 대구경의 관로(5) 건설 시에만 적용할 수 있었던 중압잭을 사람이 출입할 수 없는 중소구경의 관로 건설시에도 적용할 수 있도록 하여 경간거리를 확대하는 효과를 얻을 수있다.As described above, according to the present invention, the medium pressure jack, which was applicable only when constructing a large-diameter conduit 5, which can be accessed by a person, can be applied even when constructing a conduit of small and medium-diameter that cannot be accessed by a person. The effect of enlarging the distance can be obtained.
또한, 본 발명은 도심지일수록 비개착으로 통신관로를 설치할 필요성이 높지만 이에 반하여 도심지이기 때문에 케이블의 분기를 위한 맨홀의 설치구간이 조밀하여야 하는 구간에 효율적으로 적용할 수 있다.In addition, the present invention has a higher necessity to install a communication channel in a non-attached area, but on the contrary, it can be efficiently applied to a section in which a manhole for the branching of a cable has to be dense since it is a downtown.
