본 고안의 연약지반 상하수도관 침하방지용 방석매트 지지구조에 관한 것으로서, 더욱 상세하게는 지하 연약지반에 매설되는 상하수도관에 있어서, 상기 상하수도관을 지지하는 기초콘크리트와 터파기한 지반의 표면을 수평이 되도록 까는 바닥다짐모래의 사이에 방석매트를 설치하고, 상기 방석매트의 휘어짐이나 뒤틀어짐을 방지하도록 양단부에 지지연결대봉을 관통 설치하고, 상기 방석매트가 지면과의 수평을 이루기위해 다수개의 지지말뚝을 상기 지지연결대봉에 설치함으로써, 연약지반의 침하 및 붕괴로 인해 지지력을 잃은 상하수도관이 휘어지거나 뒤틀어져 파 손되는 것을 방지되도록 하는 연약지반 상하수도관 침하방지용 방석매트 지지구조에 관한 것이다.The present invention relates to a cushion mat support structure for preventing settlement of soft ground water and sewage pipes, and more specifically, in a water and sewage pipe embedded in underground soft ground, the surface of the foundation concrete and the ground which supports the water and sewage pipes are leveled. Install a cushion mat between the floor compaction sand, and install a support connecting rod at both ends to prevent the cushion mat from warping or twisting, and the plurality of support piles to raise the level of the cushion mat horizontally with the ground. By installing on the support connecting rod, it relates to a cushion mat support structure for preventing settlement of soft ground water and sewage pipes to prevent the water and sewage pipes lost support due to the settlement and collapse of the soft ground to be bent or twisted.

일반적으로, 공장, 주택 및 각종 시설에 상수를 공급하는 상수도관과, 사용된 하수도 폐수를 원격지의 하수처리시설로 이송시킬 수 있는 하수도관은 지상의 공간확보 및 생활환경미화를 위해 지하에 매설된다.Generally, water pipes for supplying water to factories, houses, and various facilities, and sewer pipes that can transfer used sewage wastewater to remote sewage treatment facilities are buried underground to secure ground space and to beautify living environment. .

한편, 상기 상하수도관의 매설은, 일정한 지름과 길이를 갖는 다수의 상하수도관을 일렬로 연통되게 연결한 구조물이 안착될 수 있는 충분한 공간으로 지면을 절개하고, 이곳에 상기 상하수도관 구조물을 길이방향을 따라 순차적으로 안착시킨 후 토사로 매몰함으로써 이루어진다. 이러한 종래 매설방법을 보면 단순히 땅을 파서 그곳에 상하수도관을 넣은 후 다시 땅을 덮는 방식이므로, 시공이 간편하여 널리 활용되고 있다. 특히, 도심지의 경우에는 상하수도관의 주변부에 위치되는 토사를 다져 토사들 간의 조밀도를 높이는 한편, 상하수도관이 매설된 지면상에 콘크리트나 아스팔트 등을 도포함으로써, 지반의 침하 및 붕괴로 인한 상하수도관의 파손위험이 최소화되었다. 따라서, 상하수도관의 매설에 있어서 별도의 보강공사 없이도 상기한 시공법만으로도 충분히 그 목적을 달성할 수 있었으며, 상하수도관의 안정성에도 별문제는 없었다.On the other hand, the embedding of the water supply and sewage pipe, cut the ground to a sufficient space to be seated structure that connects a plurality of water and sewage pipes having a constant diameter and length in a line, where the water and sewage pipe structure in the longitudinal direction According to the sequential seating is then buried in soil. Looking at the conventional method of embedding simply because digging the ground and put the water and sewage pipe there and then cover the ground again, the construction is easy and widely used. In particular, in urban areas, water and sewage pipes are formed by dipping soils located at the periphery of water and sewage pipes to increase the density of the soils, and by applying concrete or asphalt on the ground where water and sewage pipes are buried. The risk of breakage is minimized. Therefore, in laying the sewage pipes, the above-mentioned construction method alone was sufficient to achieve the purpose without additional reinforcement work, and there was no problem in the stability of the water pipes.

하지만, 하천유역 또는 강수량이 많은 산간지역 등 지반의 붕괴와 부분적인 침하가 빈번한 곳에서는 상기한 시공법만으로는 상하수도관을 매설하는데 한계가 있다. 즉, 상기한 시공법은 상하수도관이 일방향으로 길게 연결되어 횡압력에 대한 지지력이 극히 미약하므로, 상하수도관 매설지의 경미한 지반침하로도 상하수도관이 쉽게 휘거나 뒤틀리면서 그 일부의 파손 및 틈이 발생될 수 있고, 이러한 틈을 통해 누수 및 외부 이물질의 유입이 발생될 수 있다.However, in the case of frequent ground collapse and partial settlement, such as river basins or mountainous areas with high rainfall, there is a limit to laying water and sewage pipes only by the above construction method. That is, the above construction method is because the water supply and sewage pipes are connected in one direction long, so that the bearing capacity for the lateral pressure is very weak, even if a slight ground subsidence of the water supply and sewer pipe buried site, the water and sewage pipes can be easily bent or twisted, and some of the breakage and gaps may occur. In addition, leakage and inflow of foreign matter may occur through such gaps.

한편, 지면으로 스며든 우수는 지하의 일정장소에서 오랫동안 정체되거나 특정부분만을 집중적으로 침식시키면서 상수도관을 지지하는 지반을 약화 및 붕괴시킬 수 있고, 이를 기반으로 매설된 상하수도관에 대한 지지력 약화를 초래하여 상하수도관이 부실한 설치상태에 놓이게 되고, 이로 인해 불균형적인 지지기반에 의한 상하수도관의 연결부가 뒤틀리거나 휘어짐이 일어나면서 상하수도관 일부에 파손 및 크랙이 발생되고, 그에 따른 누수가 발생하는 문제점이 있다.On the other hand, rainwater that has soaked into the ground can weaken and collapse the ground supporting the water supply pipe while stagnating for a long time in a certain place in the underground or intensively eroding only a certain part, resulting in a weakening of bearing capacity for the water supply and sewage pipes buried based on this As a result, the water and sewage pipes are placed in a poor installation state. As a result, the joints of the water and sewage pipes are distorted or bent due to an unbalanced support base. .

따라서, 본 고안은 상기 종래의 문제점을 해소하기 위해 안출된 것으로,Therefore, the present invention is devised to solve the above conventional problems,

지하 연약지반에 매설되는 상하수도관에 있어서, 상기 상하수도관을 지지하는 기초콘크리트와 터파기한 지반의 표면을 수평이 되도록 까는 바닥다짐모래의 사이에 방석매트를 설치하고, 상기 방석매트의 휘어짐이나 뒤틀어짐을 방지하도록 양단부에 지지연결대봉을 관통 설치하고, 상기 방석매트가 지면과의 수평을 이루기위해 다수개의 지지말뚝을 상기 지지연결대봉에 설치함으로써, 연약지반의 침하 및 붕괴로 인해 지지력을 잃은 상하수도관이 휘어지거나 뒤틀어져 파손되는 것을 방지함에 그 목적이 있다.In the water and sewage pipe which is buried in the soft ground underground, a cushion mat is installed between the foundation concrete supporting the water and sewage pipe and the ground compaction sand which makes the surface of the ground broken so as to be horizontal. Water supply and sewage pipes that lost support due to the settlement and collapse of the soft ground by installing a plurality of support piles on the support connecting rods so as to penetrate the support connecting rods at both ends, and the cushion mat is level with the ground. Its purpose is to prevent bending or twisting and breaking.
