Description
본 발명은 강제 압밀 진공 탈수에 의한 지반 안정화 공법에 관한 것으로, 더욱 상세하게는 지반의 상면 기밀시트를 덮고 수분을 강제 드레인 시켜 지반을 단기간에 침하 안정화시킬 수 있도록 함을 목적으로 한 것이다.The present invention relates to a ground stabilization method by forced consolidation vacuum dehydration, and more particularly, to cover the top airtight sheet of the ground and to drain the water forcibly to settle the ground in a short time.
일반적으로, 함수비가 높은 점토, 부식토, 오닐시트 등을 포함한 연약지반의 보강은 지반의 상면에 성토작업을 통하여 지반을 안정화시키는 재하성토공법에 의하여 실시하고 있다.In general, the reinforcement of soft ground including high moisture content clay, humus soil, O'Neill sheet, etc. is carried out by loading earthwork method which stabilizes the ground through the filling work on the upper surface of the ground.
그러나, 상기한 바와 같은 재하성토공법은 많은 량의 성토를 반입하여야 하며, 성토에 따라 변화되는 지반강도에 따라 단계적으로 시공하여야 하므로 지반의 안정화 작업에 많은 시간이 소요되는 문제점이 있었다.However, the load-bearing earthwork method as described above has a problem that takes a lot of time to stabilize the ground because it must be carried in a large amount of fill, and must be constructed in stages according to the ground strength changes according to the fill.
또한, 성토과정의 토압에 의하여 주변의 지반이 변상이 발생하게 되는 문제점이 있었다.In addition, there was a problem that the surrounding ground is caused by the earth pressure of the fill process.
이에, 본 발명은 상술한 문제점을 해결하기 위하여 창출한 것으로, 지반의 상면에 기밀시트를 덥고 수분과 공기를 강제 배출시켜서 지반을 단기간에 침하 안정화 시키는 것이다.Accordingly, the present invention has been made to solve the above-mentioned problems, by heating the airtight sheet on the upper surface of the ground and forcibly discharging the moisture and air to stabilize the ground settlement in a short time.

본 발명은 지반의 수분과 공기를 강제배출시켜서 단기간에 지반을 침하 안정화시킬 수 있도록 한 것으로, 지반에 부직포와 같은 흡습체로 이루어진 수직드레인(11)을 매설하고, 상기 수직드레인(11)의 상단과 결속되며 흡수성이 좋은 부직포와 같은 흡습체로 이루어진 수평드레인(12)을 형성하며, 수평드레인(12)과 흡습가능하게 결속되는 다수의 유공집수관(13)을 설치하고, 지반의 상면에 사방 측면이 안정화 지반의 일정 깊이 까지 매설되는 기밀시트(14)를 설치하고, 상기 유공집수관(13)을 진공구동장치(15)와 연결하여서 수분과 공기를 펌핑 배출하여 지반을 안정화시키는 것이다.The present invention is to allow the ground to be settled and stabilized in a short time by forcibly discharging the moisture and air of the ground, buried in the ground vertical drain (11) made of an absorbent material such as non-woven fabric, and the upper end of the vertical drain (11) and It forms a horizontal drain (12) made of a hygroscopic body such as a non-woven fabric that is bound and absorbent good, and installs a plurality of perforated collecting pipes (13) that are hygroscopically bound with the horizontal drain (12), the sides of the ground on all sides The airtight sheet 14 which is embedded to a certain depth of the stabilized ground is installed, and the perforated collecting pipe 13 is connected to the vacuum driving device 15 to pump and discharge water and air to stabilize the ground.
여기서, 상기 기밀시트(14)의 상면에 침하계측기(16)를 구비하고 이를 침하계측기록장치(17)에 실시관으로 기록하며 침하량에 따른 진공구동장치(15)의 구동을 제어하며 지반을 안정화할 수 있도록 실시할 수 있는 것이다.Here, the sedimentation measuring instrument 16 is provided on the upper surface of the hermetic sheet 14 and recorded in the sedimentation measurement recording device 17 as a conducting pipe, and the driving of the vacuum driving device 15 according to the amount of settlement is stabilized and the ground is stabilized. It can be done to do so.
이하, 본 발명에 의한 지반 안정화 과정을 설명하면 다음과 같다.Hereinafter, the ground stabilization process according to the present invention will be described.
상기한 바와 같이 지반에 수직드레인(11) 및 수평드레인(12)을 형성하고 유공집수관(13)을 형성하며, 지반의 상면에 기밀시트(14)를 설치한 후 유공집수관(13)을 통하여 수분과 공기를 강제 배출시켜 이루어지는 본 발명은 안정화하고자하는 구획을 설정하고, 설정된 구획내부의 지반에 타설기를 이용하여 관체와 함께 부직포와 같이 흡습성 재질로 이루어진 수직드레인(11)을 타설한 후 관체를 제거하여 상기 수직드레인이 지반에 매설되게 한 후 지반의 상면에 상기 수직드레인(11)의 상부와 흡습가능하도록 결속되게 수평드레인(12)을 설치한다.As described above, the vertical drain 11 and the horizontal drain 12 are formed on the ground, and the perforated collecting pipe 13 is formed, and after the airtight sheet 14 is installed on the upper surface of the ground, the perforated collecting pipe 13 is formed. The present invention made by forcibly discharging water and air through the present invention sets a section to be stabilized, and after pouring a vertical drain 11 made of a hygroscopic material such as a nonwoven fabric with a tubular body using a pouring machine on the ground inside the set compartment, the tubular body After removing the vertical drain is buried in the ground and the horizontal drain 12 is installed on the upper surface of the ground to bind with the upper portion of the vertical drain (11) to be hygroscopic.
그리고, 수평드레인(12)과 직교되는 다수의 유공집수관(13)을 설치한 후 지반의 상면에 사방테두리가 지반의 일정깊이로 매설되게 기밀시트(14)를 설치한다.Then, after installing a plurality of perforated water collecting pipes 13 orthogonal to the horizontal drain 12, an airtight sheet 14 is installed on the upper surface of the ground so that all four edges are embedded at a predetermined depth of the ground.
또한, 상기 기밀시트(14)의 상면에 침하계측기록장치(17)와 연결되어 지반의 침하량을 측정할 수 있게한 침하계측기(16)을 설치한다.In addition, a settlement measuring instrument 16 is provided on the upper surface of the hermetic sheet 14 so as to be connected to the settlement measurement recording apparatus 17 so as to measure the settlement amount of the ground.
상기한 바와 같이 지반의 안정화 준비과정이 완료된 상태에서 진공구동장치(15)를 이용하여 유공집수관(13)을 통하여 수분과 공기를 강제배출시키게 되면 지반이 서서히 침하되게 된다.As described above, when the water and air are forcedly discharged through the hole collecting pipe 13 using the vacuum driving device 15 in the state in which the preparation for stabilization of the ground is completed, the ground is gradually settled.
한편, 수분과 공기의 강제 배출에 의한 침하의 진행상황은 침하계측기(16)에 의하여 24시간 연속감시되어 침하계측기록장치(17)에 침하과정에 있어 진공압과 지반침하량 및 배수량등의 데이터가 저장관리되는 것이다.On the other hand, the progress of settlement due to forced discharge of water and air is continuously monitored for 24 hours by the settlement instrument 16, and the data such as vacuum pressure, ground settlement amount and drainage amount are recorded in the settlement measurement device 17 during the settlement process. It is stored and managed.
이상과 같이 침하계측기록장치(17)에 기록된 정보를 이용하여 안정화시공을 관리하므로서 확실한 품질관리가 이루어지며, 지반개량강도에 대한 시공후에 품질확인조사과정에 있어 확인과 평가가 가능한 것이다.As described above, by controlling the stabilization construction by using the information recorded in the settlement measurement recording device 17, a certain quality control is achieved, and after the construction of the ground improvement strength, it is possible to check and evaluate the quality verification investigation process.
따라서, 본 발명은 안정화하고자 하는 지반의 상면에 기밀시트를 덮고 유공집수관을 통하여 지반의 수분과 공기를 강제배출시키므로서 지반이 단기간 침하 안정화되어 지반안정화작업의 공기가 단축되는 것이다.Therefore, the present invention is to cover the airtight sheet on the top surface of the ground to be stabilized by forcibly draining the ground moisture and air through the perforated water collecting pipe, the ground is settled and stabilized for a short time to shorten the air of the ground stabilization work.
또한, 대량의 성토의 반입이 필요로 하지 않으므로 공사비가 최소화되는 것이며, 지반의 안정화 과정에 있어 주변 지반의 변상이 발생하지 않는 매우 유용한것이다.In addition, the construction cost is minimized because a large amount of filling is not required, and it is very useful that the compensation of the surrounding ground does not occur in the ground stabilization process.
