본 고안은 연약지반의 성토에 의한 연약지반 침하 거동 상태를 관측하기 위한 계측구조에 관한 것으로, 더욱 상세하게는 지반을 개량하기 위한 도로 및 단지조성을 위한 성토시 연약지반이 침하되어 거동되는 상태를 확인할 수 있도록 시공 초기 지표면에 설치되어 성토에 따른 연약지반의 침하와 지하수위 변화를 확인하기 위한 연약지반의 지하수위와 침하계측 구조에 관한 것이다.The present invention relates to a measurement structure for observing the soft ground subsidence behavior caused by the filling of soft ground, and more specifically, to check the state of the soft ground subsided during the construction of roads and complexes to improve the ground. It is related to the groundwater level and settlement measurement structure of soft ground to check the soft ground settlement and groundwater level change according to the fill.

일반적으로 연약지반의 개량효과를 확인하기 위하여 사용하고 있는 침하판 설치시 정확한 침하량을 측정하기 위해서는 침하측정봉의 수직도를 유지하는 것이 중요하며, 그러므로 성토시 침하판 주위를 먼저 성토하여 침하측정봉이 기울어지지 않도록 주위를 기울여서 성토를 해야 한다.In general, it is important to maintain the verticality of the needle rod in order to accurately measure the amount of settlement when installing the needle plate, which is used to confirm the improvement effect of the soft ground. Care should be taken to tilt the ground so that it is not supported.

하지만 현장 여건상 이러한 성토가 잘 이루어지지 않는 경우가 있고, 한번 기울어진 침하 측정봉은 다시 수직도를 유지시킨다 하더라도 그 과정에서 오차는 발생할수 밖에 없다.However, due to site conditions, such fill is not well achieved, and even if the tilting rod once tilted maintains verticality again, errors inevitably occur in the process.

도 1과 같이, 연약지반(G.L) 상에 모래층(120)이 포설되고, 모래층(120) 상부에 성토층(S)이 형성되며, 이때 성토를 실시하기전 연약지반 상에 침하판(10)을 안착하고 침하판(10)에는 중앙 상부에 침하봉(20)을 용접하며, 침하봉(20)에는 외측에 침하봉 보호관(30)을 커플링(50)을 사용하여 보호하고, 침하봉 보호관(30)의 외측에 삼발이(40)를 용접하며, 삼발이(40)에 연약지반에 지지될 수 있도록 지지철근(42)을 용접하여 지지하게 된다.As shown in FIG. 1, a sand layer 120 is installed on the soft ground GL, and a fill layer S is formed on the sand layer 120, and at this time, the settlement plate 10 is formed on the soft ground before embankment is performed. And the sinking plate 10 is welded to the sinking rod 20 in the upper center, the sinking rod 20 to protect the sinking rod protection tube 30 on the outside using the coupling 50, the sinking rod protection tube The trivet 40 is welded to the outside of the 30, and the support reinforcing bar 42 is welded to be supported by the trivet 40 so as to be supported by the soft ground.

또한, 연약지반 개량 지역의 성토 구간에서는 성토로 인해 발생한 과잉간측 수압의 소산을 확인하기 위하여 간극 수압계와 병행하여 성토 구간 내에 지하수위계(도면상 미도시함)를 설치하는데 지하수위계 파이프가 P.V.C 파이프가 사용되기 때문에 성토시 약한 충격에도 파손되기 쉽고 성토로 인한 과잉간극 수압의 영향으로 지하수위가 상승하게 된다.In addition, in the fill section of the soft ground improvement area, in order to check the dissipation of excess inter-side pressure caused by the fill, a groundwater gauge (not shown) is installed in the fill section in parallel with the pore pressure gauge. Because it is used, it is easy to be damaged even by weak impact during the filling, and the groundwater level rises due to the excess gap water pressure caused by the filling.

따라서, 지하수위계를 부지 외곽에 설치하여 성토하중의 영향을 받지 않는 부지 외곽의 지하수위를 정수압으로 결정하는 경우가 많다.Therefore, the groundwater level is often installed outside the site to determine the groundwater level outside the site that is not affected by the fill load as hydrostatic pressure.

그러나, 단지 조성시 연약지반의 개량면적은 대규모로 진행되고 부지외곽의 지하수위를 이용하여 정수압을 산정 시 간극 수압계가 매설된 위치와의 거리가 일반적으로 최소 70 ~ 500M 정도의 이격 거리가 있어 이를 이용하여 정수압을 산정시 큰 오차를 유발하는 결과가 나타날 수 있다.However, the improvement area of the soft ground at the time of construction is large scale and the distance from the position where the pore hydrometer is buried is generally at least 70 ~ 500M when calculating the hydrostatic pressure by using the groundwater level outside the site. It can cause a big error when calculating hydrostatic pressure.

이러한 연약지반의 성토 시공을 할 경우 이에 따른 침하 거동 및 지하수위 변화를 측정하기 위하여 간편한 개선책들이 필요한 실정이라 할 수 있다.When the construction of such soft ground is carried out, simple improvement measures are needed to measure the settlement behavior and groundwater level change.

본 고안은 상술한 내용을 감안하여 고안한 것으로, 본 고안은, 연약지반을 개량 목적으로 성토 시공시 성토에 따른 영향을 최소화하여 보다 정확한 침하 상태를 측정할 수 있고 지하수위 변화를 파악하여 효율적인 연약지반의 계측관리를 할 수 있도록 하는 연약지반의 지하수위와 침하계측 구조를 제공함을 그 목적으로 한다.The present invention was devised in view of the above-mentioned contents, and the present invention can minimize the effects of land fill during construction for the purpose of improving the soft ground, so that more accurate settlement can be measured and the groundwater level changes can be effectively understood. Its purpose is to provide groundwater level and settlement measurement structure of soft ground to enable the measurement and management of the ground.
