도 2는 본 발명에 따른 지중매설관의 시공방법을 보인 개요도이다.2 is a schematic view showing a construction method of the underground buried pipe according to the present invention.
먼저, 소정 깊이의 관로(11)를 목적한 길이만큼 형성한 다음, 상기 관로(11) 바닥면의 흙에 적당량의 팽창성 경화재 조성물을 혼합하여 소정의 두께로 고화시킨다음, 그 경화층(12)상에 복수의 지중매설관(14)을 얹어 상호 연결하는 한편, 상기 지중매설관(14)의 양측부에 흙과 적당량의 팽창성 경화재 조성물을 혼합.조성하여 경화벽(13)을 형성한 상태에서 상기 지중매설관(14)을 토사로 매몰한다.First, the conduit 11 of a predetermined depth is formed to a desired length, and then, an appropriate amount of the expandable curing agent composition is mixed with the soil of the bottom surface of the conduit 11 and solidified to a predetermined thickness. While placing a plurality of underground buried pipe 14 on the interconnection, while the soil and the appropriate amount of the expandable hardener composition is mixed on both sides of the underground buried pipe 14 to form a hardened wall (13) The underground buried pipe 14 is buried in soil.
이때, 상기 팽창성 경화재 조성물은 이미 대한민국 특허공고번호 제 83-448에 개제된 것으로, 이의 주성분은 15-40wt%의 석고와; 25-40wt%의 용광로슬랙과; 30-50wt%의 포오틀랜트 세멘트와; 알루미나 세멘트, 알루미늄금속의 재용해에서 얻어지는 알루미늄 슬러지, 태운 알루나이트, 알루마이트 슬러지, 보오크사이트의 용해과정에서 발생되는 레드머디 슬랙으로 이루어진 군으로부터 선택된 1내지 10wt% 알루미네이트 등으로 구성된다.At this time, the expandable hardener composition is already disclosed in the Republic of Korea Patent Publication No. 83-448, its main component is 15-40wt% gypsum; A furnace slag of 25-40 wt%; 30-50 wt% of Portland cement; 1 to 10 wt% aluminate selected from the group consisting of alumina cement, aluminum sludge obtained from redissolution of aluminum metal, burned aluminite, aluminite sludge, and red mud slag generated during the dissolution of bauxite.
상기 팽창성 경화재 조성물에 관해서 좀 더 상세히 부연하면, 이를 구성하고 있는 주성분의 배합비율은 15-40wt%의 석고, 25-40wt%의 용광로슬랙, 그리고 30-50wt%의 포오틀랜트 세멘트로 되어 있으며, 알루미네이트의 혼합비율은 1내지 10wt%이고, 상기 원료들을 가루로 분해해서 서로 혼합하게 되며, 이때의 비표면적은 2,500-4,500㎠/g의 범위도 바람직하다.In more detail with respect to the expandable hardener composition, the blending ratio of the main components constituting the expandable hardener composition is 15-40 wt% gypsum, 25-40 wt% furnace slag, and 30-50 wt% portant cement. The mixing ratio of the aluminate is 1 to 10wt%, and the raw materials are decomposed into powder and mixed with each other, and the specific surface area is preferably in the range of 2,500-4,500 cm 2 / g.
여기에서, 알루미네이트는 알루미나세멘트, 알루미늄제품 생산과정에서 알루미늄금속을 재용해시 백 필터(bag filter)에 의해 수집된 소위 슬러지 파우더, 버언트 알루나이트, 알루마이트 슬러지, 보오크 사이트의 용해과정에서 레드머디 슬랙과 같은 알루미나성분들을 포함하는 물질이다.Here, the aluminate is red in the process of dissolving the so-called sludge powder, variant aluminite, aluminite sludge, and bauxite, collected by a bag filter when re-melting aluminum metal in the production process of alumina cement, aluminum product. It is a material containing alumina components such as mud slag.
따라서, 상기 팽창성 경화재 조성물로서 경화층(12)과 경화벽(13)의 시공과정을 상세히 설명하면, 15-40wt%의 석고, 25-40wt%의 용광로슬랙, 그리고 30-50wt%의 포오틀랜트 세멘트, 알루미네이트의 혼합비율은 1내지 10wt%인 원료들을 가루로 분해해서 서로 혼합된 팽창성 경화재 조성물을 적당량의 물에 용해시켜 흙과 혼합하거나 살포하여 경화층(12)을 형성한 다음, 경화층(12)에 얹혀진 지중매설관(14)의 양측에 상기와 같은 방법으로 팽창성 경화재 조성물과 혼합된 흙을 적치시켜 경화시킨다.Therefore, the construction process of the cured layer 12 and the hardened wall 13 as the expandable hardener composition will be described in detail, 15-40wt% gypsum, 25-40wt% furnace slag, and 30-50wt% portland. The mixing ratio of cement and aluminate is 1 to 10wt% of the raw materials are decomposed into powder, and the expandable hardener composition mixed with each other is dissolved in an appropriate amount of water, mixed with or sprayed with soil to form a hardened layer 12, and then a hardened layer. The soil mixed with the expandable hardener composition is deposited on both sides of the underground buried pipe 14 placed on (12) in the same manner as above to cure.
한편, 또 다른 팽창성 경화재 조성물은 탄산나트륨 10-15%과: 탄산카리윰 8-12%와: 유산나트륨 0.5-16.5%와; 유산카리윰 1-5%와; 염화나트륨 0.5-16.5%와; 염화카리윰 20-26%와; 염화 마그네슘 13-19%와; 염화 제2철 2-7%와; 염화알루미늄 1.5-5%와; 염화칼슘 5-10%와; 염화 코발트 0.05-1%와; 구연산 0.05-4%: 등을 혼합하여 된 것이며, 이와 같이 조성되는 팽창성 경화재 조성물은 사용되는 토양의 수분 함유량의 정도에 따라 적당량의 물에 용해시켜서 경화재 수용액을 만든 다음, 흙과 혼합하거나 살포하여 경화층(12)을 형성한 다음, 경화층(12)에 얹혀진 지중매설관(14)의 양측에 상기와 같은 방법으로 팽창성 경화재 조성물과 혼합된 흙을 적치시켜 경화시킨다.On the other hand, another expandable curing agent composition is 10-15% sodium carbonate and: 8-12% caricol carbonate: 0.5-16.5% sodium lactate; Lactic acid carbide 1-5%; Sodium chloride 0.5-16.5%; Carichlor chloride 20-26%; With 13-19% magnesium chloride; 2-7% ferric chloride; 1.5-5% of aluminum chloride; Calcium chloride 5-10%; Cobalt chloride 0.05-1%; 0.05-4% citric acid: It is made by mixing and the like, and the expandable curing agent composition thus prepared is dissolved in an appropriate amount of water according to the degree of moisture content of the soil used to make an aqueous solution of the curing agent, and then mixed with the soil or sprayed to cure. After the layer 12 is formed, the soil mixed with the expandable hardener composition is deposited on both sides of the underground pipe 14 placed on the cured layer 12 in the same manner as above to cure.
이때, 상호 경화되는 시간을 살펴보면 약 3시간이 경과되었을 때, 흙과 시멘트의 응집성형이 완료되고, 3일 양생시 정상적인 강도가 발생하며 7일 양생후에는 최대강도로 변하게 된다.At this time, when looking at the time of mutual curing, when the coagulation of the soil and cement is completed after about 3 hours, the normal strength occurs in three days curing, and after 7 days curing will change to the maximum strength.
따라서, 본 발명은 지중매설관이 매설되는 관로의 바닥흙을 팽창성 경화재조성물과 혼합하여 고화시킨 다음, 그 경화층상에 지중매설관을 연결시키므로서 부동침하로 인한 지중매설관의 연결부분의 이완. 파손을 방지하고, 또한 지중매설관의 시공을 간편하게 하는 동시에 지중매설관의 시공비를 크게 절감할 수 있는 매우 유용한 발명이다.Accordingly, the present invention is to mix the bottom soil of the pipeline in which the underground buried pipe is buried with the expandable hardening material composition and solidify, and then connect the underground buried pipe on the hardened layer, the relaxation of the connection portion of the underground buried pipe due to the floating settlement. It is a very useful invention that can prevent damage, and also simplify the construction of the underground buried pipe and greatly reduce the construction cost of the underground buried pipe.
