본 발명은 간척지, 해안, 강변, 연못, 수렁, 늪지대등의 점성토로 이루어진 연약지반에 수직드레인(Vertical Drain)을 타입하여 연약한 지반의 내부에 함유되어 있는 물을 더욱 효율적으로 탈수시키는 공법에 있어서, 연약지반의 상부로 여과용주름구조의 원통형드레인이 시공설치되게 하고, 연약지반의 하부에는 중공보드드레인 구조의 판형드레인이 시공설치되도록 결합시킨 원통형 및 판형복합 수직드레인을 사용함으로써, 수직드레인의 전체적인 구조를 원통형드레인으로만 으로 시공한 경우와 또는 판형드레인만으로 시공한 경우에 비하여 다량침하로 인하여 상부에서 드레인의 절곡현상이 발생되더라도 배수기능이 저하되는 일이 없이 탈수작용을 원활하게 발휘 할 수 있는 원통형 및 판형 복합드레인에 의한 연약지반의 탈수촉진공법 및 그 물건에 관한 것이다.The present invention is a vertical drain (Vertical Drain) type on the soft ground composed of viscous soil, such as reclaimed land, shore, riverside, pond, bogs, swamps, etc. in a method for more efficiently dewatering the water contained in the soft ground, The cylindrical drain of filter structure is installed on the upper part of the soft ground, and the cylindrical and plate composite vertical drains are bonded to the lower part of the soft ground to install the hollow board drain structure. Compared to the case where the structure is constructed only with the cylindrical drain or only with the plate-shaped drain, even if the drainage bending occurs in the upper part due to the large settlement, the dehydration function can be smoothly performed without deterioration of the drainage function. Dehydration Promotion Method of Soft Ground by Cylindrical and Plate Type Composite Drains and Its Articles It is about.

종래에는 도 1 에서 도시한 바와 같이 요입배수공(5)을 뚫은 요입륜(2)과 돌출륜(3)으로 연설된 원통형주름관체(6)의 둘레부에 여과포(4)를 둘러씌워 형성한 구조의 원통형드레인(1)만으로 연약지반의 지중까지 수직드레인으로 심설하여 연약지반(7)의 내부에 함유되어 있는 물을 탈수 하도록 시공설치하였으나 이는 간극수의 함유량이 적고 수직드레인의 절곡현상이 작은 하부지반에 까지 원통형주름관체(6)로 구성된 원통형드레인(1)을 사용하므로서 전체적인 시공설치비용이 높아 지는등 비경제적인 결점이 있다.In the related art, as shown in FIG. 1, the filter cloth 4 is formed on the periphery of the cylindrical wrinkle pipe 6 protruded into the inlet ring 2 and the protruding ring 3 through the inlet drainage hole 5. It is installed in the vertical ground to the ground of the soft ground with only the cylindrical drain (1), and installed to dehydrate the water contained in the soft ground (7), but this is the lower ground where the content of the gap water is small and the bending of the vertical drain is small. By using the cylindrical drain (1) consisting of a cylindrical corrugated pipe 6 until there is an uneconomical disadvantage, such as the overall construction installation cost increases.

또한 도 2 에서 도시한 바와 같은 전면주벽(8)과 후면주벽(8a) 및 격벽(9)에 의하여 수직탈수통로(10)를 형성하는 중공판체(6a)의 둘레부에 여과포(4a)를 둘러 씌운 구조의 판형드레인(1a)을 수직드레인으로서 연약지반(7)의 지중으로 심설하여 연약지반(7)의 내부에 함유되어 있는 물을 탈수하도록 시공설치하였으나 이는 판형드레인(1a)의 제작이 용이하여 제작비용이 저렴한 이점은 있으나 연약지반(7)의 내부에 함유되어 있는 물이 여과포(4a)를 통하여 유입되는 과잉간극수의 상부유수단면적이 적으므로 과잉간극수의 배출을 저해하여 연약지반의 탈수기능이 원활하지 못하는 등의 결점이 있으며, 침하량이 과대한 상부에서는 절곡현상이 크게 발생하여 지그재그의 현상이 되는데 이때 판형드레인(1a)이 손상을 입어 배수기능이 저하되는 결점이 있다.In addition, the filter cloth 4a is enclosed in the periphery of the hollow plate body 6a forming the vertical dewatering passage 10 by the front circumferential wall 8, the rear circumferential wall 8a, and the partition 9 as shown in FIG. The plate-shaped drain 1a of the covered structure was installed in the ground of the soft ground 7 as a vertical drain and installed to dewater the water contained in the soft ground 7, but this is easy to manufacture the plate-shaped drain 1a. Although the manufacturing cost is low, the water contained in the soft ground (7) has a small upper upper surface area of excess pore water flowing into the filter cloth (4a), thereby inhibiting the discharge of the excess pore water and dehydrating the soft ground. There is a defect such as not smooth, the excessively settled in the upper portion of the bending phenomenon occurs largely zigzag phenomenon is a phenomenon that the plate-shaped drain (1a) is damaged and the drainage function is reduced.
