연약지반 개량용 배수재의 공랭식 제조방법 {Air-cooled manufacturing method for drainage material for soft ground improvement}Air-cooled manufacturing method for drainage material for soft ground improvement}

본 발명은 연약지반 개량용 배수재의 공랭식 제조방법에 관련되며, 보다 상세하게는 폴리프로필렌(PP) 원료를 판형 보드로 압출 성형하는 단계에서 부터 필터지를 피복하여 배수재를 완성하기까지 수행되는 각 단계별 일련의 제조공정이 단일 공정으로 연속 수행되고, 기존 수냉방식을 공랭방식으로 전환하여 압출물을 냉각하도록 구조 개선함에 따라 기존 수냉식 제품 대비 인장강도, 측압이 20%이상 향상됨과 더불어 배수성능이 월등이 우수하게 개선되며, 특히 코어원판 사이즈를 광폭으로 확장 성형한 후, 이를 세절하여 한번에 복수의 코어를 제조하므로 수냉식 제조공정 대비 시간당 생산량이 크게 증가될 수 있는 연약지반 개량용 배수재의 공랭식 제조방법에 관한 것이다.The present invention relates to an air-cooled method of manufacturing a drainage material for improving soft ground, and more specifically, a series of steps performed from the step of extruding a polypropylene (PP) raw material into a plate-shaped board to completing the drainage material by covering filter paper. The manufacturing process of is continuously carried out as a single process, and the structure is improved to cool the extrudate by converting the existing water cooling method to the air cooling method. As a result, the tensile strength and side pressure are improved by more than 20% compared to the existing water-cooled products, and the drainage performance is superior. In particular, it relates to an air-cooled manufacturing method of a drainage material for improving soft ground, which can greatly increase the production per hour compared to a water-cooled manufacturing process, since the core disk size is expanded and molded in a wide width and then shredded to produce a plurality of cores at once. .

일반적으로 건설 공사의 지층이 지중수를 함유한 연약지반인 경우에는 먼저 그 토양의 지중수를 배출시키고 지반을 압밀침하 시킨 후 기초공사를 하도록 되어 있다. 이러한 연약지반의 공사단계에서는 다양한 방법으로 지중수를 배출하도록 할 수 있는데, 종래에는 일반적으로 자갈과 모래를 지층에 깔고 이를 성토함으로써 지층의 지중수를 빼내도록 하고 있었다.In general, if the stratum of a construction project is a soft ground containing ground water, the ground water from the soil is first discharged and the ground is condensed and then the foundation work is done. In the construction stage of such a soft ground, groundwater can be discharged in various ways. In the past, gravel and sand are generally laid on the stratum and filled to remove groundwater from the stratum.

이에 최근에는 드레인 보드라고 불리우는 배수재를 이용하여 지층의 지중수를 배출하는 기술이 보급되고 있는 추세이다. 드레인 보드는 플라스틱 소재로 구성되는 다양한 형상의 드레인 보드가 시판되고 있으며, 재질적인 측면에서 모래보다 많이 저렴하고, 성능적인 측면에서도 효율이 높아 건설현장에서 많이 채택되고 있지만, 합성수지재로 성형제조된 배수코어를 부직포로 이루어진 필터재가 감싸도록 형성하는 구조적 특성상 제조공정이 연속적으로 수행되는 못하는 실정이다.Accordingly, in recent years, a technology for discharging groundwater in the stratum by using a drainage material called a drain board is spreading. Drain boards of various shapes composed of plastic materials are commercially available, and they are much cheaper than sand in terms of material, and are widely adopted in construction sites because of their high efficiency in terms of performance, but drainage made of synthetic resin materials. Due to the structural characteristics of forming the core so that the filter material made of non-woven fabric is wrapped, the manufacturing process cannot be performed continuously.

이에 종래에 개시된 등록특허 10-0935817호에서, 배수 코어를 공급하는 코어 공급부; 상기 코어의 진행 경로와 인접하게 배치되어, 상기 진행되는 코어를 향해 필터재를 공급하는 필터재 공급부; 상기 코어와 필터재를 감싸도록 형성되어, 상기 필터재가 상기 코어를 감싼 채로 양단부가 중첩되도록 유도하는 유도부; 상기 필터재의 중첩된 부분을 향하도록 배치되어 상기 중첩된 부분을 용융시켜 접합 되게 하고, 상기 중첩된 부분에 열을 가하는 가열기를 포함하는 용융 접합 유닛; 및 상기 중첩된 부분을 기준으로 상기 가열기에 대응되게 배치되어, 상기 가열기와 협동하여 용융 영역이 결정되게 하는 영역 결정부를 포함하는 기술이 선 제시된바 있다.Accordingly, in Patent No. 10-0935817 disclosed in the prior art, a core supply unit for supplying a drainage core; A filter material supply unit disposed adjacent to a traveling path of the core and supplying a filter material toward the progressing core; An induction part formed to surround the core and the filter material, and guide both ends to overlap while the filter material surrounds the core; A melt bonding unit including a heater disposed to face the overlapped portion of the filter material to melt and bond the overlapped portion, and apply heat to the overlapped portion; And a region determining unit arranged to correspond to the heater based on the overlapped portion so as to determine a melting region in cooperation with the heater.

그러나, 상기 종래기술은 드레인 보드의 제조 공정을 자동화하기 위한 것이나, 압축된 코어가 냉각수 탱크에 저장된 물과 같은 액체에 의해 냉각되도록 구성됨에 따라 코어 제조 폭 확장에 한계가 따르고, 이로 인해 코어가 소폭으로 압출 성형되어 하나의 제조라인에서 생산가능한 배수재가 1줄로 제한되어 생산성이 크게 저하되는 문제점이 따랐다.However, the prior art is for automating the manufacturing process of the drain board, but as the compressed core is configured to be cooled by a liquid such as water stored in the cooling water tank, there is a limit to the expansion of the core manufacturing width, and thus the core is slightly reduced. There was a problem that productivity was greatly reduced because the number of drainage materials that were extruded and produced in one production line was limited to one line.
