본 발명은 침하방지용 상수도관 설치구조에 관한 것으로서, 보다 상세하게는 매립되는 상수도관의 외주연 상부와 하부에 순차적으로 설치되어 상수도관이 설치되는 지역의 침하나 변형 등의 발생시 지반과의 마찰력으로 인해 상수도관의 침하나 변형을 방지하고, 동시에 안전하고 견고한 상태로 상수도관을 매설시킬 수 있으며, 인근의 터파기 공사중 지중에 매립된 상수도관의 외측을 보호하여 굴착기로 인한 상수도관의 파손을 미연에 방지할 수 있는 침하방지용 상수도관 설치구조에 관한 것이다.The present invention relates to a water pipe installation structure for preventing settlement, and more particularly, it is installed in the upper and lower periphery of the outer circumference of the water pipe to be buried in order to friction with the ground when the settlement or deformation of the area where the water pipe is installed. Due to this, it is possible to prevent the sedimentation or deformation of the water supply pipe, and at the same time, to bury the water supply pipe in a safe and solid state, and to protect the outside of the water supply pipe buried in the ground during the excavation work, thus preventing the water supply pipe from being damaged by the excavator. The present invention relates to a water pipe installation structure for preventing settlement.

일반적으로, 공장이나 주택 및 각종 시설에 상수를 공급하는 상수도관은 수원수를 사람이 마시기에 적합한 물로 급수하기 위한 시설로서, 지상의 공간 확보 및 생활 환경미화를 위해 지상에서부터 일정한 깊이의 지하에 매설되는 데, 이와 같은 상수도관의 매설 작업은 일정한 직경과 길이를 갖는 다수의 상수도관을 일렬로 연통되게 연결한 구조물이 안착될 수 있도록 충분한 공간으로 지면을 절개하고, 이곳에 상수도관 구조물을 길이 방향을 따라 순차적으로 안착시킨 후 토사로 매몰하므로써 매설 작업을 완료하게 된다.In general, water supply pipes supplying water to factories, houses, and various facilities are facilities for supplying water source with water suitable for human drinking, and are buried underground to a certain depth from the ground to secure ground space and beautify the living environment. The buried work of such a water pipe is made by cutting the ground into a space sufficient to allow a structure in which a plurality of water pipes having a constant diameter and length are connected in a line is placed therein, and the water pipe structure is longitudinally connected thereto. After the sediment is settled sequentially, the landfill work is completed by burying the soil.

이러한 종래의 상수도관 매설 방법을 살펴 보면 단순히 땅을 파서 그곳에 상수도관을 넣은 후 다시 땅을 덮는 방식이므로 시공이 간편하여 널리 활용되고 있으며, 특히 도심지의 경우에는 상수도관의 주변부에 위치하고 있는 토사를 다져 토사들간의 조밀도를 높이는 한편, 상수도관이 매설된 지면상에 콘크리트나 아스팔트 등을 도포하므로써 지반의 침하 및 붕괴로 인한 상수도관의 파손 위험을 최소화하고 있다.Looking at the conventional method of laying the water pipes, it is simply used to dig the ground, put the water pipes there and then cover the ground again, so the construction is easy to use widely, especially in the downtown area to compact the soil located in the periphery of the water pipes While increasing the density between the soil and soil, by applying concrete or asphalt on the ground where water pipes are buried, the risk of water pipe damage due to settlement and collapse of the ground is minimized.

한편, 통상적으로 상기 수도관은 수압을 견딜만한 우수한 내압성이 요구되므로 비교적 강도가 강한 금속 재질 즉, 주물이나 압연강판을 원형으로 접어서 용접한 강철관으로 제작되고, 서로 이웃하는 상수도관의 연결부에는 실링과 같은 방수 작업을 통해 누수 및 오염 물질의 침투를 방지하지만, 상수도관은 우수에 의해 부식이 쉽게 이루어지는 금속 재질이므로 지면으로 스며든 우수와 오랜 시간 동안 접촉하게 되면 조금씩 부식이 진행되면서 그 사용 수명을 단축시키게 되며, 이로 인해 상수도관의 보수 공사 및 교체가 빈번하게 발생될 수밖에 없었다.On the other hand, the water pipe is typically made of a relatively strong metal material, that is, a steel pipe welded by folding a casting or a rolled steel plate in a circular shape, because the excellent pressure resistance to withstand the water pressure, and the connection portion of the adjacent water pipes, such as sealing Waterproofing prevents leakage of water and contaminants, but water pipes are made of metal that can easily be corroded by rainwater. As a result, maintenance work and replacement of water pipes were frequently generated.

특히 노출에 의한 파손을 방지하기 위하여 땅속에 매립하는 구조로 되어 있으므로, 빗물 등과 같은 우수가 지하의 일정 장소에서 오랫동안 정체되거나 특정 부분만을 집중적으로 침식시키게 되면, 상수도관을 지지하는 기반이 붕괴되거나 약화되어 상수도관의 일부분이 내려앉을 수 있고, 원통형으로 되는 상수도관의 특성상 매립지가 연약지반인 경우 지지면적의 부족으로 인한 상수도관의 자중에 의해 침하되는 현상이 발생하였으며, 이로 인해 상수도관의 연결부가 뒤틀리거나 휨 등이 발생되면서 상수도관의 일부에 파손 및 크랙이 발생되며, 이 파손 및 크랙이 발생된 부분으로 누수 및 오염 물질이 유입되는 등의 많은 문제점이 있었다.In particular, since the structure is buried in the ground to prevent damage caused by exposure, if the rainwater, such as rainwater stagnates for a long time in a certain place in the basement or intensively erodes only a certain part, the foundation supporting the water supply pipe is collapsed or weakened. Part of the water supply pipe can be settled down, and due to the characteristics of the water supply pipe, which is cylindrical, the landfill is soft ground, which is caused to sink due to the weight of the water supply pipe due to the lack of supporting area. As warpage or bending occurs, breakage and cracks are generated in a part of the water pipe, and there are many problems such as leakage and contaminants introduced into the breakage and cracks.

또한, 강수량이 많은 장마철에 연약지반으로 빗물이 침투하는 경우 종래의 상수도관 매립구조에서는 배수시설을 갖추고 있지 않았기 때문에 연약지반의 지지력을 더욱 약화시켜 상수도관의 침하를 더욱 가속화시키는 문제점도 있었다.In addition, when rainwater penetrates into the soft ground during the rainy season with a lot of precipitation, the conventional water pipe buried structure does not have a drainage facility, thereby further weakening the bearing capacity of the soft ground and further accelerating the settlement of the water pipe.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 매립되는 상수도관의 외주연 상부와 하부에 순차적으로 설치되어 상수도관이 설치되는 지역의 침하나 변형 등의 발생시 지반과의 마찰력으로 인해 상수도관의 침하나 변형을 방지하고, 동시에 안전하고 견고한 상태로 상수도관을 매설시킬 수 있으며, 인근의 터파기 공사중 지중에 매립된 상수도관의 외측을 보호하여 굴착기로 인한 상수도관의 파손을 미연에 방지할 수 있는 침하방지용 상수도관 설치구조를 제공함에 그 목적이 있다.The present invention is to solve the problems as described above, the water supply pipe due to the frictional force with the ground when the sedimentation or deformation of the area where the water supply pipe is installed is sequentially installed in the upper and lower outer periphery of the buried water pipe. It can prevent the sinking or deformation, and at the same time, bury the water supply pipe in a safe and solid state, and protect the outside of the water supply pipe buried in the ground during the excavation work to prevent damage to the water supply pipe due to the excavator. The purpose is to provide a water pipe installation structure for preventing settlement.

또한, 상수도관(40) 인근의 굴착기기로 인한 지반의 터파기 공사중 상수도관(40)의 외측을 감싸는 사방확장고정구(20)의 전방좌우측고정봉살(25,26)과 후방좌우측고정봉살(27,28) 및 전후방좌측고정봉살(25,27)과 전후방우측고정봉살(26,28)의 상면에서 좌우측의 관통공(31,31a)이 고정너트(32)로 체결고정된 다수개의 삼각절곡대(30)와 먼저 충돌하여 상수도관(40)이 외부충격에 의해 파손되는 것을 방지하게 된다.In addition, the front left and right fixed rods (25, 26) and the rear left and right fixed rods (27, of the four-way expansion fixture 20 surrounding the outside of the water supply pipe 40 during the excavation of the ground due to the excavation equipment near the water supply pipe 40) 28) and a plurality of triangular bent bars in which the left and right through-holes 31 and 31a are fastened to the fixing nuts 32 at the upper surfaces of the front and rear left fixing rods 25 and 27 and the front and rear right fixing bars 26 and 28, respectively. The first collision with 30) prevents the water supply pipe 40 from being damaged by an external impact.

이와 같이, 본 발명은 매립되는 상수도관의 외주연 상부와 하부에 순차적으로 설치되어 상수도관이 설치되는 지역의 침하나 변형 등의 발생시 지반과의 마찰력으로 인해 상수도관의 침하나 변형을 방지하고, 동시에 안전하고 견고한 상태로 상수도관을 매설시킬 수 있으며, 인근의 터파기 공사중 지중에 매립된 상수도관의 외측을 보호하여 굴착기로 인한 상수도관의 파손을 미연에 방지할 수 있는 효과가 있다.As such, the present invention is installed in the upper and lower outer peripheral edge of the water supply pipe to be buried in order to prevent the settlement or deformation of the water supply pipe due to frictional force with the ground when the settlement or deformation of the area where the water supply pipe is installed, At the same time, it is possible to bury the water supply pipe in a safe and solid state, and to prevent the damage of the water supply pipe due to the excavator by protecting the outside of the water supply pipe buried in the ground during the excavation work.

본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.
