Description

단지조성시의 상,하수관 매설방법{LAYING METHOD OF WATER SUPPLY AND DRAIN ON HOUSING COMPLEX}LAYING METHOD OF WATER SUPPLY AND DRAIN ON HOUSING COMPLEX}

본 발명은 상,하수관 매설방법에 관한 것으로서, 상세하게는 부분적인 터파기 및 되메우기 작업으로 상,하수관을 매설해 줄 수 있도록 한 것이다.The present invention relates to a method for embedding water and sewage pipes, and in particular, to allow the water and sewage pipes to be buried by partial trenching and backfilling.

각종 시설물이나 구조물을 신축하기 위한 단지조성시에는 성토와 절토 및 굴착등을 통한 토목공사가 우선되어야 하고 또 그 시설물이나 구조물이 골프장이나 산업단지 및 주거단지등과 같이 상,하수시설을 필요로 할 경우 상,하수관을 매설한 다음 필요시설물이나 구조물들을 시공해 주어야 한다.When constructing a complex to build various facilities or structures, civil works through fill, cut and excavation should be prioritized, and the facilities or structures need water and sewage facilities such as golf courses, industrial complexes and residential complexes. In case of water supply and sewage pipes, the necessary facilities or structures should be installed.

그러나 토목공사의 경우 미리 짜여진 사업계획에 따라 진행된다 하더라도 이후 사업계획이 변경될 수가 있고 또 사업계획의 변경이 없다 하더라도 성토와 절토 및 굴착등을 통한 토목공사 중 상,하수관 매설이 이루어지도록 할 경우 날카롭고 큰 깬돌등이 상,하수관과 접촉된 상태에서 작업을 위하여 지나다니는 중장비와 다짐작업시 가해지는 토압등이 가해짐에 따라 상,하수관의 균열이나 크랙이 발생될 우려가 있어 토목공사후 전구간에 걸친 별도의 터파기 및 되메움작업을 통하여 상,하수관을 매설해 주도록 하고 있다.However, in the case of civil engineering work, even if it is proceeded according to the pre-designed business plan, the business plan may be changed afterwards, and even if there is no change in the business plan, the laying of water and sewage pipes is carried out during the civil engineering work through embankment, cutting, and excavation. There is a risk of cracks or cracks in the water and sewage pipes due to heavy equipment passing for work in the state where sharp and large crushed stones are in contact with the water and sewage pipes and earth pressure applied during the compaction work. The sewer and sewage pipes are to be buried through separate digging and backfilling.

따라서 토목공사후 별도의 장비와 인력을 동원하여 상,하수관을 설치해 주고자 하는 전구간의 터파기작업 및 되메우기작업으로 상,하수관을 매설해 주도록 하는데 시간이 추가소요되므로 공사기간이 늘어나게 됨은 물론 그에 따라 공사비용이 현저하게 늘어나게 된다.Therefore, after the civil works, additional time is needed to bury the water and sewage pipes through the opening and refilling of the bulbs to install water and sewage pipes by mobilizing separate equipment and manpower. The cost will increase significantly.

또한 지하에 매설되는 상,하수관의 경우 부식을 염려하여 거의 대부분은 합성수지관이 이용되는데, 별도공사를 통하여 상,하수관을 매설해 준다 하더라도 매설시 이용되는 흙은 토목공사시 발생되는 깬돌등을 다량포함하고 있는 것으로서, 흙에 포함된 돌을 일일이 가려낼 수 없는 작업현실을 감안할때 날카로운 깬돌이 상,하수관과 접촉된 상태로 매설되어 이후 진행되는 흙다짐작업등에 의해 토압이 작용할시 상,하수관의 균열로 이한 부실시공으로 이어지게 되며, 이러한 류의 부실시공은 물론 오랜사용에 의한 상,하수관의 교체시에는 매설된 기존 상,하수관을 모두 파헤쳐서 새 상,하수관으로 교체한 다음 되메움작업해 주어야 하므로 재시공시에도 시간과 비용이 과다소요된다.Also, in case of water and sewage pipes that are buried underground, most of them are synthetic resin pipes, and most of them use synthetic resin pipes. Considering the reality of the work that cannot contain the stones contained in the soil, the sharp crushed stone is buried in contact with the upper and sewer pipes, and the earth and sewage pipes are actuated by the soil compaction process. This will lead to sub-constructions caused by cracks, and when replacing upper and lower sewer pipes as well as long-term use of these types, the existing upper and sewer pipes that have been buried must be dug up and replaced with new ones and sewer pipes, and then backfilled. Therefore, too much time and money are required for reconstruction.

또한 상,하수관은 아무런 보온수단없이 매설되고 또 매설시에는 깊게 매설될수록 시간과 비용이 추가소요되는바, 이로 인하여 얕은 깊이로 매설되므로 근래의 잦은 이상기온으로 예기치 못한 한파가 찾아오게 되면 동파발생으로 큰 불편을 주게 됨은 물론 동파된 상,하수관을 교체하기 위한 비용을 지출하여야 하는등 많은 문제점들이 있는 것이다.In addition, water and sewage pipes are buried without any warming means, and when they are deeply buried, additional time and money are required. Therefore, they are buried at a shallow depth. There are many problems, such as a great inconvenience, as well as the expense of replacing the freezing water and sewage pipes.

본 발명은 토목공사후 부분적인 터파기와 되메움작업만으로도 상,하수관을 매설해 줄 수 있도록 하여 상,하수관을 매설하는데 따른 기간과 비용을 현저히 줄여줄 수가 있고 또 매설용 흙에 포함된 날카로운 깬돌이나 다짐작업시의 토압등에 의해 상,하수관의 손상 내지는 균열발생우려가 전혀 없으며, 혹여 손상된 파이프를 이용함에 따른 누수발생이나 또는 노후된 파이프의 교체시에도 부분적인 터파기와 되메움작업으로 전체 상,하수관의 교체가 이루어질 수가 있어 재시공시에도 시공기간과 비용을 절감해 줄 수가 있으며, 더나아가 얕은 깊이로 매설되더라도 우수한 보온력으로 동파를 방지해 줄 수가 있는 단지조성시의 상,하수관 매설방법을 제공하고자 한다.The present invention is able to bury the water and sewage pipes only by partial dig and backfilling work after civil engineering can significantly reduce the period and cost of laying the water and sewage pipes, and sharp crushed stone or compacted in the soil for laying There is no possibility of damaging or cracking the water and sewage pipes due to earth pressure during work, and even replacing the whole water and sewage pipes by partial breakage and backfilling in case of water leakage or replacement of old pipes. The construction time and cost can be reduced even during reconstruction. Furthermore, even if it is buried at a shallow depth, it is intended to provide a method for laying water and sewage pipes in the construction of a complex that can prevent freezing with excellent thermal insulation.

본 발명의 목적은 토목공사시 사업계획에 의해 미리 주어진 상,하수관 매설지점에 매설해 주고자 하는 상,하수관의 직경보다는 큰 직경의 보호관을 매설하여 토목공사후 기매설된 보호관의 일부를 노출시켜서그 내부에 상,하수관을 삽입설치해 주도록 한 단지조성시의 상,하수관 매설방법에 의해 달성된다.The purpose of the present invention is to expose a part of the protective pipes buried after the civil works by embedding a protective pipe of a diameter larger than the diameter of the water and sewage pipes to be buried at the buried point of water and sewage pipes given in advance by the business plan during civil engineering work It is achieved by the method of laying the water and sewage pipes at the time of the construction of the water and sewage pipes.

본 발명은 토목공사시 상,하수관(2)이 매설되는 위치에 매설해 주고자 하는 상,하수관(2)보다 큰 직경의 보호관(4)을 매설하여 토목공사후 부분적인 터파기로 매설된 보호관(4)의 일부가 노출되게 한 다음 그 보호관(4)을 컷팅하여 내부에 상, 하수관(2)을 삽입설치해 주도록 함으로서, 상,하수관(2)의 전체 매설구간중 극히 일부구간의 터파기와 되메움작업으로 상,하수관(2)을 매설해 줄 수가 있게 되므로 상,하수관의 매설을 위한 시공기간과 비용을 현저히 줄여줄 수가 있게 된다.The present invention is to embed the protective pipe (4) of a larger diameter than the water and sewage pipe (2) to be buried in the position where the water, sewage pipe (2) is buried during civil engineering protection pipe (4) ) To expose a part of) and cut the protective pipe (4) so that the upper and sewage pipes (2) are inserted into the inside, so that the excavation and backfilling of a very small portion of the entire buried section of the upper and the sewer pipes (2) As the water and sewage pipes (2) can be buried, construction time and costs for laying the water and sewage pipes can be significantly reduced.

또한 보호관(4)은 매설과정에서 되메움흙에 포함되는 깬돌과 다짐작업시의 토압등에 의해 일부손상되거나 균열이 발생된다 하더라도 상,하수관의 삽입에는 지장을 줄 우려가 없을 뿐 아니라 삽입설치후 보호관에 의한 보호로 손상내지는 균열발생우려가 전혀 없어 시공과정에서의 부실시공우려를 없애줄 수가 있게 된다.In addition, the protection pipe (4), even if some damage or cracks are caused by the crushed stone included in the backfilling soil and earth pressure during the compaction process during the buried process, there is no risk of damaging the insertion of the water and sewage pipe as well as the protection pipe after installation There is no risk of cracking or damage caused by the protection by the system, and it is possible to eliminate the secondary work concerns in the construction process.

또한 상,하수관으로서 손상된 파이프를 사용함에 따라 뒤늦게 누수가 발견되거나 또는 오랜사용에 의한 노후로 교체를 요할 경우에도 일부구간의 터파기로 보호관(4)을 노출시켜서 파이프를 교체한 다음 되메움해 주는 것으로 전구간의 교체작업이 이루어질 수 있게 되므로 기조성된 지상의 조경수나 주위환경의 환경파괴없이 단기간에 저렴한 비용부담만으로 교체해 줄 수가 있게 되며, 더나아가 보호관(4)에 의한 보온효과로 얕게 매설되더라도 동파우려가 없어 동파에 의한 불편함은 물론 불필요한 금전적 지출을 없애줄 수가 있게 되는 등의 많은 효과가 있는 것이다.In addition, even when leaks are found late due to the use of damaged pipes as water and sewage pipes, or when replacement is required due to aging due to long use, the pipes are replaced by exposing the protection pipes (4) with the opening of some sections and then backfilled. It is possible to replace the light bulbs, so that it can be replaced with low cost in a short period of time without the landscaping of the ground or environmental damage of the surrounding environment. There are many effects such as being able to eliminate unnecessary financial expenses as well as inconvenience caused by freezing.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거 상세히 설명하기로 하며, 다만 토목공사시에는 지반상태나 이용용도등에 따른 일반적인 사항이나 공법 및 응용되는 기술들에 대한 자세한 설명은 간략히 하거나 생략하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the case of civil works, detailed descriptions of general matters, construction methods, and applied technologies according to the ground state or use will be briefly or omitted. .

도 1은 본 발명 시공시를 나타낸 일부평단면구성도이고, 도 2는 본 발명 시 공후를 보여주는 일부측단면구성도로서, 본 발명은 조성하고자 하는 지형이나 지질등에 따라 성토와 절토 및 굴착등을 통한 기반조성과정에서 미리 계획된 사용계획을 참고로 하여 상,하수관(2)을 매설해 주고자 하는 곳에 상,하수관(2)보다 직경이 큰 보호관(4)을 적정깊이로 매설한다.1 is a partial planar cross-sectional view showing the construction of the present invention, Figure 2 is a partial cross-sectional view showing the construction of the present invention, the present invention according to the topography or geology, such as the earth and cut and excavation, etc. The protective pipe (4) having a larger diameter than the water and sewage pipe (2) is buried at an appropriate depth in the place where the water and sewage pipe (2) is to be buried with reference to the planned use plan in advance.

다만 본 발명은 소규모단지 조성시 적용하기 위한 것으로서, 이용되는 보호관(4)은 재질을 불문하고 어느정도 휨이 가능한 것이면 만족하나, 그 직경은 150mm이하의 것을 사용한다.However, the present invention is intended to be applied when forming a small-scale complex, the protective tube (4) used is satisfactory if it can be bent to some extent regardless of the material, the diameter is less than 150mm is used.

또한 보호관(4)의 매설시 각진 부위는 연결구등을 이용하여 연결하고 또 그 연결부위는 맨홀(6)을 설치하여 맨홀을 통하여 노출되도록 할 수도 있으며, 맨홀(6)의 설치유무와 관계없이 보호관(4)의 매설후에는 그 매설위치를 확인할 수 있도록 지면에 표지판을 세워두거나 또는 GPS등을 통한 위치정보를 저장하여 매설위치를 파악할 수 있도록 하는 것이 바람직하다.In addition, when embedding the protective tube 4, the angular portion may be connected using a connector, and the connecting portion may be exposed through the manhole by installing a manhole 6, regardless of whether or not the manhole 6 is installed. After buried in (4), it is desirable to put a sign on the ground so that the buried position can be checked, or to store the location information through GPS, so that the buried position can be identified.

또한 토목공사시 매설되는 보호관(4)은 매설시 흙에 포함된 깬돌등이 접촉한 상태에서 다짐작업등에 의해 토압이 작용할시 일부손상되거나 균열이 발생될 우려가 있다 하겠으나, 보호관은 상,하수관(2)을 보호해 주기 위한 것으로서, 손상내지는 균열이 발생되더라도 그 내부에 상,하수관이 삽입될 수 있는 형태를 유지할 수 있으면 만족하므로 보호관의 손상 내지 균열은 크게 염려하지 않아도 된다.In addition, the protective pipe (4) buried during the civil engineering work may cause some damage or cracks when earth pressure is applied by the compaction work in the state that the crushed stone, etc. in contact with the soil when buried, but the protective pipe is a water pipe, sewage pipe ( 2) To protect the protection, even if the damage or crack occurs, it is satisfied if it can maintain the shape that can be inserted into the upper and sewer pipes inside, so the damage or cracks of the protection tube do not have to be greatly concerned.

토목공사후에는 매설된 보호관(4)의 직선구간 중 일부구간을 터파기 하여 그 공간부(8)를 통하여 보호관(4)이 노출되게 하고, 노출된 보호관(4)의 일부를 컷팅제거하거나 또는 컷팅후 서로 상반된 방향으로 휜 상태에서 그 내부에 상,하수 관(2)을 삽입설치한다.After the civil engineering work, a part of the straight sections of the buried protective pipe 4 is broken so that the protective pipe 4 is exposed through the space part 8, and the part of the exposed protective pipe 4 is cut off or cut. After inserting the upper and lower sewage pipes (2) therein in the state 휜 in the direction opposite to each other.

이때 이용되는 상,하수관은 이제껏 부식방지를 위하여 가장 널리 이용되어온 합성수지재 파이프나 주름관등으로서, 이들은 휨성이 우수하므로 보호관(4) 내에 용이하게 삽입해 줄 수가 있게 되며, 그 직경은 100mm이하로 하여 휨성을 갖도록 하면서 보호관(4) 내에 용이하게 삽입해 줄 수 있도록 한다.The water and sewage pipes used at this time are synthetic resin pipes and corrugated pipes which have been most widely used for corrosion prevention, and they are easily bent into the protective pipes 4 because of their excellent warpage properties. It is to be easily inserted into the protective tube (4) while having a bendability.

즉 상,하수관(2)은 직경이 클 경우 합성수지재라 하더라도 작업자에 의한 취급 내지는 휨이 어려우므로 직경이 100mm 이하의 것을 사용하는 것이 바람직하며, 그에 따라 보호관(4) 또한 상,하수관(2)이 여유있게 삽입될 수 있는 직경이 150mm이하의 것을 사용하는 것이 바람직하다.That is, the upper and the sewage pipe (2), even if the diameter is large, even if the synthetic resin material is difficult to handle or bend by the worker, it is preferable to use a diameter of 100mm or less, accordingly, the protective pipe (4) and the upper and sewage pipe (2) It is preferable to use a diameter of 150 mm or less that can be easily inserted.

또한 상,하수관(2)을 보호관(4) 내에 삽입할 시 그 보호관이 일직선으로 매설된 경우 하나의 공간부(8)만으로 양방향 원하는 길이만큼의 상,하수관(2)을 삽입설치해 줄 수가 있게 되나, 보호관(4)이 각진 부위를 포함할 경우 각진 부위를 사이에 두고 있는 각각의 직선 부위에 공간부를 마련하여 각각 각진 부위에 이르기까지 상,하수관(2)을 삽입하고 그 각진 부위는 미리 형성된 맨홀 내지는 부분적인 터파기로 하나의 공간부(8)를 더 갖도록 하여 그 공간부(8)를 통하여 좌우 상,하수관(2)을 연결구등으로 연결한 다음 되메움작업해 주는 것으로 상,하수관(2)의 매설작업이 완료된다.In addition, when the upper and lower sewer pipes 2 are inserted in the protective pipe 4, when the protective pipes are buried in a straight line, only one space 8 can insert and install the upper and lower sewer pipes 2 as long as desired. When the protective tube 4 includes an angled portion, a space is provided at each straight portion with the angled portion interposed therebetween, and the upper and sewer pipes 2 are inserted up to the angled portion, and the angled portion is a preformed manhole. Or a partial trench to have one more space (8) by connecting the left and right upper and lower sewer pipes (2) with a connector or the like through the space (8) and then backfilling the water, sewer pipe (2) Buried work is completed.

그리고 상,하수관(2)을 매설하기 위한 공간부(6)(8) 중 직선구간에 형성되는 공간부(8)는 특정할 필요는 없으나, 지관의 연결을 요하는 위치에 형성해 주게 되면 상,하수관(2)을 보호관(4)내에 삽입하여 연결하고 또 삽입설치된 상,하수관(2) 에 지관을 연결하여 지상으로 노출되게 한 다음 되메움작업해 주는 것으로 더이상의 터파기작업없이 상,하수관의 매설 및 지관연결작업이 완료된다.The space portion 8 formed in the straight section of the space portions 6 and 8 for embedding the upper and the sewage pipes 2 does not need to be specified, but is formed in a position requiring the connection of the branch pipes. The sewer pipe (2) is inserted into the protective pipe (4) and connected, and the branch pipe is connected to the inserted and installed sewage pipe (2) so that it is exposed to the ground, and then backfilled. Buried and branch connection work is completed.

또한 이러한 상,하수관(2)의 매설작업과정에서나 또는 매설후에는 상,하수관(2)이 보호관(4) 내에 위치하여 보호관(4)에 의해 보호되므로 매설시의 흙에 포함된 깬돌과 다짐작업시 가해지는 토압등에 의해 상,하수관이 손상되거나 균열이 발생될 우려가 전혀 없고 더 나아가 동절기에는 보호관(4)에 의한 보온효과로 얕게 매설되더라도 동파우려가 없게 된다.In addition, during or after the buried work of the water and sewage pipe (2), the water and sewage pipe (2) is located in the protective pipe (4) is protected by the protective pipe (4), so the crushed stone and compaction work contained in the soil at the time of buried There is no risk of damaging or cracking the water and sewage pipes due to the earth pressure, etc., and even in winter, there is no possibility of freezing even if it is shallowly buried by the warming effect by the protection pipe (4).

더나아가 매설시 이용된 상,하수관(2)이 불량제품이라 매설후 누수가 발견되거나 또는 오랜사용에 의한 노후로 교체를 요할 시에는 초기매설작업시와 같이 전체매설구간 중 부분적인 터파기로 공간부(6)(8)를 형성하여 그 공간부(6)(8)를 통하여 기존 상,하수관(2)을 보호관(4)으로부터 분리제거하고 새 상,하수관을 삽입설치한 다음 되메움작업해 주는 것으로 교체작업이 완료되므로 교체작업시에도 시간과 비용을 절감할 수가 있게 됨은 물론 기조성된 지상물의 파괴를 최소화할 수가 있게 되는 것이다.Furthermore, if the water and sewage pipes (2) used at the time of the burial are defective products and leaks are found after they are buried or if they need replacement due to aging due to prolonged use, the space may be partially broken in the entire burial section as in the initial burial work. (6) (8) is formed to separate and remove the existing water and sewage pipes (2) from the protective pipe (4) through the spaces (6) and (8), insert and install new water and sewage pipes, and then backfill them. As the replacement work is completed, it is possible to save time and money during the replacement work, as well as to minimize the destruction of the existing ground.
