Description

점성토 연약지반의 탈수 촉진을 위한 심지드레인Wick drainage for promoting dewatering of soft clay soft ground

본 발명은 강변이나 높지대등의 점성토로 이루어진 연약지반에 모래, 자갈 흙등을 성토한 연약지반의 내부에 함유되어 있는 수분(물)의 탈수를 촉진하기 위하여 사용되는 점성토 연약지반의 탈수 촉진을 위한 심지드레인에 관한 것으로, 간단한 구조로서 용이하게 제작하여 제작비를 크게 절감할 수 있으며, 사용시에 대량의 운송 및 취급을 간편하게 할 수 있도록 함에 주안점을 둔 것이다.The present invention is a wick for promoting the dewatering of the soft clay soft ground used to promote the dehydration of water (water) contained in the soft ground in which the sand, gravel soil, etc. in the soft ground consisting of viscous soil, such as riverbanks and altitudes. The present invention relates to a drain, which is easy to manufacture as a simple structure, which can greatly reduce manufacturing costs, and focuses on simplifying a large amount of transportation and handling during use.

종래에 플라스틱 요철판의 둘레부에 부직포를 둘러씌운 구조의 심지드레인에 있어서는 플라스틱요철부(골판)를 별도의 형틀에 의해 제작하여야 하는 번거러움과 사용시에 운송 및 취급이 불편한 결점이 있었다. 이를 해결하기 위하여 제안된 여과용 주름배수관을 이용한 점성토 연약지반의 탈수 촉진공법(1996.3.22일 공고 번호 제96-3745호)에 있어서는 탈수작용이 원활한 효과는 있으나 구조가 복잡한 주름관체를 별도로 제작한 다음, 그 둘레부에 별도의 여과포를 피복시켜야 되므로 구조 및 제작이 복잡하여 제작비가 많아지며, 제품의 부피가 크므로 사용시에 운송 및 취급이 불편한 결점이 있었다.Conventionally, in the wick drain structure having a nonwoven fabric wrapped around the periphery of the plastic concave-convex plate, the inconvenience of having to produce the plastic concave-convex part (corrugated plate) by a separate mold and the inconvenience of transportation and handling in use. In order to solve this problem, in the method of promoting the dewatering of soft clay ground using the pleated drainage pipe for filtration (No. 96-3745, dated June 22, 1999), dehydration effect is smooth but complex corrugated tube is manufactured. Next, a separate filter cloth is to be coated on the periphery thereof, so the structure and manufacturing are complicated, and the manufacturing cost increases, and the volume of the product has a disadvantage in that transportation and handling are inconvenient during use.

또한, 발포스티롤등의 합성수지 구상체를 부직포등의 포지내에 충진하여 기둥형상으로 형성한 구조에 있어서는 단순히 별개로 독립된 구조로서 시공작업시에 별개로 시공되어야 되는 번거러운 결점이 있었다.In addition, in the structure in which a spherical body such as foamed styrole is filled in a column such as a nonwoven fabric and formed into a columnar shape, there is a cumbersome drawback in that it is simply an independent structure and must be separately constructed at the time of construction work.

본 발명은 종래의 결점을 적게하기 위하여 제안된 것으로서 배수가 원활한 부직포를 중첩한 상태에서, 그 중첩단부를 깊이방향으로 한개 또는 수개의 봉침선을 봉침설하여 그 내부가 길이방향으로 망포(網包)형상이 되도록 제작하여 두루마리로 권취시킨 상태에서 적정길이 또는 시공장소에 적합한 길이로 절단한 다음, 망포형상의 내부에 경량의 입상스치로폴알맹이나 경량의 인공자갈골재, 자연쇄석콩자갈 및 짚새끼다발 등을 서로 혼합하여 주거나 또는 각각 별도로 충진하여 주므로서 하나 또는 수개로 연결된 배수용 심지가 되는 점성토연약지반의 탈수 촉진을 위한 심지드레인을 얻을 수 있도록 한 것으로서 간편하고 용이하게 제작하여 제작비를 크게 절감할 수 있으며, 경량이므로 제작 및 사용시에 운반 및 취급이 용이하며, 수개로 연결된 배수용심지를 동시에 시공하므로서 시공작업을 간편하게 할 수 있으며, 시공장소의 입지조건에 따라 적합하도록 시공현상에서 직접설치할 수 있도록 하였다.The present invention is proposed in order to reduce the drawbacks of the prior art, in the state of overlapping non-woven fabrics having a smooth drainage, one or several seams of the overlapping end is sewn in the depth direction, the inside of the net cloth (網 包) Manufactured to be shaped and wound with a roll, cut to a suitable length or length suitable for a city factory, and then a lightweight granular scalloped grain or lightweight artificial gravel aggregate, natural crushed soybean gravel and straw bundles inside the mesh cloth shape. It is possible to obtain a wick drain for promoting the dewatering of the viscous earth ground, which becomes a drainage wick connected by mixing each other or filling each other separately, or by filling them separately. It is light and easy to carry and handle when it is manufactured and used. The construction wicks can be installed at the same time, and the construction work can be done easily.
