Description
본 발명은 연약지반 처리를 위한 진공압밀공법 적용시 사용되는 기밀시트와 표면 매립층 포설 공사를 고화토-지오텍스타일 복합체(1)을 사용함으로써, 공사기간의 단축 및 공사비를 절감할 수 있는 연약지반 진공압밀공법이다.The present invention is a soft ground vacuum that can reduce the construction period and reduce the construction cost by using a high-fiber soil-geotextile composite (1) for laying the airtight sheet and surface buried layer used in the application of vacuum consolidation method for soft ground treatment It is a consolidation method.
일반적으로 준설 매립된 연약 지반 위에 시설물 등을 설치하여 부지로 이용하기 위해서 여러 가지 압밀 공법이 사용된다. 특히, 진공압밀공법은 연약지반에하중을 가하는 방법으로 대기압을 사용함으로써, 성토 하중을 위한 토사가 필요하지 않아 토사가 많지 않은 지역이나 대규모 연약 지반 처리를 해야 할 지역에서 매우 유리한 공법이다. 또한 진공압밀공법은 상당한 심도까지 일정하게 압밀을 가할 수는 장점이 있다.Generally, various consolidation methods are used to install facilities on the ground of dredged soft ground. In particular, the vacuum consolidation method is a very advantageous method in the area where there is not much soil due to the use of atmospheric pressure as a method to apply the soft ground, there is no need for earth soil for the fill load or large soft ground treatment. In addition, the vacuum consolidation method has the advantage that it can be consistently consolidated to a considerable depth.
그러나, 현재 사용되고 있는 방법 또한 수직 배수재(2) 설치 등을 위하여 연약지반 위에서 장비 작업의 필요성 때문에 연약지반 위에 매립층을 약 1m 정도 포설하고, 그 후에 진공압력이 충분히 가해지도록 기밀시트 또한 설치해야 한다. 대규모의 연약지반을 처리하는 경우, 상당량의 토사가 필요하게 되는 데, 환경 파괴가 중요한 문제로 대두되는 지금의 상황에서 토사의 확보가 상당히 곤란한 문제가 되고 있다. 또한 진공압밀공법에서 핵심적인 역할을 하는 기밀 시트가 상당히 고가여서 연약지반공사에 진공압밀공법의 적용이 어려운 실정이다.However, the method currently used also has to install a buried layer of about 1 m on the soft ground for the installation of vertical drainage (2), etc. because of the necessity of the operation of the equipment on the soft ground, and then also to install the airtight sheet so that the vacuum pressure is sufficiently applied. In the case of treating a large amount of soft ground, a considerable amount of soil is required. In the present situation where environmental destruction is an important problem, securing of soil is becoming a difficult problem. In addition, since the airtight sheet, which plays a key role in the vacuum consolidation method, is very expensive, it is difficult to apply the vacuum consolidation method to soft ground works.
한편, 수직 배수재를 기밀 시트를 관통시켜서 파이프로 진공 펌프와 연결하여 진공압을 가하는 진공압밀공법은 대규모 부지에 적용할 경우 기밀시트에 상당히 많은 천공을 해야 하며 복잡한 파이프의 연결로 공사에 상당한 어려움이 수반되는 단점이 있다.On the other hand, the vacuum consolidation method in which the vertical drainage penetrates the airtight sheet and connects the vacuum pump to the pipe to apply a vacuum pressure requires a large amount of perforation to the airtight sheet when applied to a large site. There are accompanying drawbacks.
따라서, 진공압밀공법은 매립층의 토사 문제, 고가의 기밀 시트의 문제점을 해결해야 할 필요가 있다.Therefore, the vacuum consolidation method needs to solve the problem of the earth and sand of the buried layer and the expensive airtight sheet.
본 발명은 상기의 문제를 해결하기 위한 것으로, 고강도와 차수성을 가진 고화토와 높은 배수 능력을 가진 지오텍스타일을 결합하여, 표면 매립층 공사, 기밀시트의 설치 및 배수 문제점를 동시에 해결하고자 한다.The present invention is to solve the above problems, by combining a high-strength and high-grade soils and geotextiles with a high drainage capacity, to solve the problem of surface buried layer construction, installation of the airtight sheet and drainage at the same time.

본 발명은, 진공압밀공법을 연약지반에 적용하기 위하여 연약지반 위에 표면 매립층의 포설 없이 직접 고화토-지오텍스타일 복합체(1)을 설치하여 장비가 바로 작업할 수 있으며, 고화토-지오텍스타일 복합체(1)이 기밀 시트의 역할하며, 진공 펌프와 지오텍스타일이 연결되어 배수로의 역할을 하는 것을 특징으로 한다. 본 발명에 의한 시공 순서는 다음과 같다. 연약지반에 고화토-지오텍스타일 복합체(1)을 포설하고 장비가 바로 진입하여 수직 배수재(2)를 설치한 후 기밀성을 유지하기 위하여 고화토로 상부를 밀봉하게 된다. 지오텍스타일과 진공펌프(3)를 파이프로 연결하는 과정을 거친 후 진공 펌프(3)를 작동시켜 진공압을 가하여 지중의 물을 빨아들여 연약지반의 압밀을 촉진하게 된다.The present invention, in order to apply the vacuum consolidation method to the soft ground, directly install the solidified soil-geotextile composite (1) without laying the surface buried layer on the soft ground, the equipment can work directly, the solidified soil-geotextile composite ( 1) It serves as an airtight seat, and the vacuum pump and the geotextile are connected to serve as a drain. The construction sequence according to the present invention is as follows. After installing the Gohwa-Geotextile complex (1) on the soft ground and the equipment enters immediately and installs the vertical drainage (2), the top is sealed with the goats to maintain airtightness. After the process of connecting the geotextile and the vacuum pump (3) by a pipe, the vacuum pump (3) is operated to apply a vacuum pressure to suck the water in the ground to facilitate the consolidation of the soft ground.
본 발명의 핵심인 고화토-지오텍스타일 복합체(1)은 배수 능력이 뛰어난 일반 지오텍스타일(5)에 CAS계의 고화토(4)로 처리하여 제작되어, 고화토(4)의 고강도와 표면의 차수성 및 하부 지오텍스타일(5)의 높은 배수능력을 갖게 된다. 이 때 고화토-지오텍스타일 복합체(1)의 전체 두께는 지반의 상태에 따라 조절 가능하며, 강도 또한 조절이 가능하다.The high-fiber soil-geotextile composite (1), which is the core of the present invention, is manufactured by treating the general geotextile (5) having excellent drainage capacity with a solidified soil (4) based on CAS, and thus, It has the high degree of drainage and the lower geotextile 5. At this time, the total thickness of the Gohwa-Geotextile composite (1) can be adjusted according to the condition of the ground, the strength can also be adjusted.
이하, 본 발명의 바람직한 실시 예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 2 shows the shape of the Gohwa-Geotextile Composite (1), where the Gohwa (4) fills the voids of the Geotextile (5) and the Goats (4) and Geotextiles on top of the Geotextile (5). (5) is integrally behaved at the same time to have the characteristics of the order and strength of the solidified soil (4) and the toughness and flexibility of the geotextile (4) at the same time. In addition, the solidified soil 4 used in the present invention has good adhesion between the solidified soils, so that when there is a problem in airtightness during work, it is easy to reinforce later.
이상과 같이 고화토-지오텍스타일 복합체(1)을 연약지반 표면의 매립층 대신 사용함으로써 매립토사의 문제 및 고가의 기밀시트의 대체가 가능하게 되어 공사비 및 공사기간의 단축이 가능하게 된다.By using the high-fiber soil-geotextile composite 1 in place of the buried layer on the surface of the soft ground as described above, it becomes possible to replace the problem of landfill soil and expensive airtight sheets, thereby reducing the construction cost and construction period.
