Description
본 고안은 조립식 맹암거에 대한 것으로서, 특히 맹암거 시공에 있어서 부직포가 외측면상에 부착된 외부의 다공형 철판과 내부의 플라스틱유공관으로 구성되고 유공관과 철판의 사이에 골재를 충진함으로써 시공이 용이하고 도로절취사면의 용출수를 최소화할 수 있어 도로절취사면의 유실이 방지되고 도로 절취사면의 안정성이 유지되며,공사비가 절감되는 조립식 이중필터 맹암거에 대한 것이다.The present invention is for the prefabricated blind culvert, and especially in the construction of the blind culvert, it is composed of the outer perforated iron plate and the inner plastic perforated pipe with the nonwoven fabric attached to the outer surface, and the construction is easy by filling the aggregate between the perforated pipe and the iron plate. It is possible to minimize the elution of the road cut slopes to prevent the loss of the road cut slopes, to maintain the stability of the road cut slopes, and to reduce the cost of construction.
일반적으로 토목공사 및 조경공사에 포함되는 도로건설이나 운동장, 잔디광장 등의 공사시에 널리 시공되는 배수공법 중 심토층 배수공사로 시공하고 있는 맹암거는 토양공극내에 함유되어 있는 수분의 양을 적게하거나 지하수위를 차단 혹은 저하시켜서 토질의 유실을 방지함은 물론 토질의 내구력을 증진시키고 식물의 생육을 촉진시키기 위한 배수공법이다.In general, the Bum-A-Geul, which is constructed by sub-soil drainage, is a small amount of water contained in soil voids, which is widely used in road construction, sports ground, and grass plaza. In addition, the groundwater level is blocked or lowered to prevent loss of soil, as well as to improve the durability of the soil and to promote the growth of plants.
즉 중력배수공법의 하나로 심토층내 함유되어 있는 과잉수를 배제하기 위하여 암거를 매설하는 것으로서 암거의 매설은 불투수층까지 굴착한 후 투수성재료를 채워넣어 상부를 복토하여 심토층내에 함유된 수량을 배수시키는 것이다.In other words, as one of the gravity drainage methods, culverts are embedded to remove excess water contained in the subsoil layer. The culverts are excavated to an impermeable layer, filled with permeable material, and covered with the top to drain the water contained in the subsoil layer. .
이와 같이 시공되는 종래의 맹암거는 제1도의 사용상태도에서 알 수 있는 바와 같이 시공중인 지표층을 설계도면에 표시된 깊이까지 굴착하여 터파기를 한 후 부직포(3)를 깔고 부직포(3)상에 유공관(1)을 부설하고 그 위에 투수층을 이루도록 골재(2)를 투입하여 구거를 충진시킨후 부직포(3)를 봉합하고 그 위에 복토를 하여지표층을 만들게 되면 시공이 완료되는 것이다. 이때 부직포(3)는 토질조건상 토양입자가 물과 같이 흘러서 유공관(1)의 내부로 유입되어 유공관(1)이 막히는 것을 방지하기 위한 필터로서 기능한다. 그러면 지하수나 우천시 지표층에서 심토층으로 흡수되는 물은 부직포(3)와 골재(2)를 거쳐 배수망이 형성된 유공관(1)의 통공을 통해서 내부로 모이게 되어 물은 유공관(1)을 따라 배수가 되는 것이다.As shown in the use state diagram of FIG. 1, the conventional blind lumber constructed as described above is excavated by excavating the ground layer under construction to the depth indicated in the design drawing, and then laying the nonwoven fabric 3 and installing the perforated pipe on the nonwoven fabric 3 ( 1) Lay out and put aggregate (2) to form a permeable layer on it to fill the pores and then suture the non-woven fabric (3) and cover it to create a surface layer is completed construction. At this time, the nonwoven fabric 3 functions as a filter for preventing soil particles from flowing into the perforated pipe 1 due to soil conditions and flowing into the perforated pipe 1. Then, the water absorbed from the groundwater or the rainy ground surface layer is collected through the non-woven fabric (3) and the aggregate (2) through the through-hole of the perforated pipe (1) where the drainage network is formed, and the water is drained along the perforated pipe (1). Will be.
이러한 종래의 맹암거는 터파기 작업에 있어서, 골재의 투입시 과량의 골재가 투입되거나 과소의 골재가 투입되어 일정한 품질을 유지하기가 곤란하고 부직포로 유공관 및 골재를 둘러 싸야 하므로 부직포가 많이 필요하게 되며, 이로인해 공사비용이 과다하게 되고 자재관리 노무관리등의 시공관리의 어려움이 발생하게 되고, 다량의 필터용 골재가 필요하게 되므로 시공가가 고가로 되는 문제점이 있었다.In the conventional blind dig dig operation, it is difficult to maintain a certain quality due to the input of excess aggregate or under-aggregate when the aggregate is added, it is difficult to maintain a certain quality and to surround the perforated pipe and aggregate with a non-woven fabric, so a lot of non-woven fabric As a result, the construction cost is excessive, the difficulty of construction management such as material management labor management, and the need for a large amount of filter aggregates, there was a problem that the construction cost is expensive.
본 고안의 목적은 부직포를 다공형 철판에 부착하여 부직포의 낭비를 막고, 일정한 품질의 시공이 가능하며, 이를 통하여 지하수위를 낮추고 침투수의 처리 및 지하수를 여과하여 유입시킨 후 배수처리를 수행하는 조립식 이중필터 맹암거를 제공하는 것이다.The purpose of the present invention is to attach the nonwoven fabric to the porous iron plate to prevent the waste of the nonwoven fabric, and the construction of a certain quality is possible. Through this, the groundwater level is lowered, the infiltration water is filtered and the groundwater is filtered and introduced to perform the drainage treatment. It is to provide a prefabricated double filter blind culvert.
본 고안의 다른 목적은 골재를 유공철판과 유공관 사이에 충진하여 적은 양의 골재로 효율적으로 사용함으로써 시공비용이나 관리비용 등이 월등히 절감되는 것이 가능한 조립식 이중필터 맹암거를 제공하는 것이다.Another object of the present invention is to provide a prefabricated double filter blind culvert that can be significantly reduced in construction costs and management costs by filling the aggregate between the perforated steel sheet and the perforated pipe efficiently using a small amount of aggregate.
본 고안의 다른 목적은 맹암거의 윗부분을 철판으로 마무리 함으로써 도로의꺼짐을 방지하고 보다 안정적인 시공이 가능하며, 골재간의 공극을 일정하게 유지하게 되어 지하수 등의 물을 효과적으로 배수하고 반영구적으로 사용할 수 있도록 하는 조립식 이중필터 맹암거를 제공하는 것이다.Another object of the present invention is to finish the upper part of the blind gamyeo by the iron plate to prevent the road off and more stable construction, and to maintain the air gap between the aggregates to effectively drain water such as groundwater and use semi-permanently It is to provide a prefabricated double filter blind culvert.
본 고안의 이러한 목적들은 부직포(3)가 외측면상에 부착된 외부의 유공 철판(4)과 내부의 플라스틱유공관(1)으로 구성되고 유공관(1)과 유공철판(4)의 사이에 골재(2)를 충진한 조립식 이중필터 맹암거에 의하여 달성된다.These objects of the present invention are composed of an outer perforated iron plate 4 and an inner plastic perforated pipe 1 having a nonwoven fabric 3 attached to an outer surface thereof, and having an aggregate 2 between the perforated pipe 1 and the perforated iron plate 4. It is achieved by a prefabricated double filter blind culvert filled with).

In addition, by finishing the upper part of the blind pit with iron plate, it prevents the road from turning off and the groundwater passed through the nonwoven fabric 3 flows through the through hole of the perforated steel sheet 4, and then naturally filters through the pores of the aggregate and the plastic perforated pipe. The effect can be obtained.
실시예2는 제 5도에 나타난 바와 같이 상기의 플라스틱유공관(1) 내부에 보다 작은 통공을 갖는 유공관(5)을 하나 더 추가로 설치하고 외부의 유공철판(4) 또한 여러 겹으로 배치한 후 그 사이 공간에는 충진골재로서 모래, 25mm자갈, 45mm자갈, 55mm자갈을 내부에서 외부로 갈 수록 큰 공극을 갖도록 차례로 충진한다.In Example 2, as shown in FIG. 5, an additional hole tube 5 having a smaller through hole is installed inside the plastic hole tube 1, and the outer steel plate 4 is also arranged in several layers. The space between them is filled with sand, 25mm gravel, 45mm gravel, 55mm gravel in order to have larger voids from inside to outside.
본 고안의 실시예2는 실시예1에 나타난 바와 같은 본 고안의 구조적 특성을 이용하여 여과기능을 증대시킨 것으로서, 하천의 바닥이나 유수지에서 여과장치로서 사용될 수 있음을 보인 것이다. 즉, 외부에서 흡수된 물이 철판의 통공과 골재의 공극을 수차례 통과함에 따라서 자연 여과 될 수 있으며 이를 상수도 취수장치로 이용되도록 한 것이다.Example 2 of the present invention is to increase the filtration function by using the structural characteristics of the present invention as shown in Example 1, it was shown that it can be used as a filtration device in the bottom of the river or the reservoir. In other words, the water absorbed from the outside can be naturally filtered by passing through the pores of the iron plate and the pores of the aggregate several times, which is to be used as a water intake device.
본 고안에 따른 조립식 이중필터 맹암거는 도로나 운동장 등의 시공시에 지표하부에 설치되며 원형의 플라스틱 유공관(1)과 외측의 유공철판(4) 사이에 골재(2)가 충진되고 상기 유공철판(4)의 외표면상에는 부직포가 부착되어 물의 배수가 효율적으로 이루어지며 일정량의 부직포만을 사용하므로 종래 맹암거 시공에 수반되던 부직포의 낭비를 막고, 필터용 골재의 요구량이 감소하게 되어 운반비용이나 인건비 등의 시공비용이 절감되고, 골재의 과다 또는 과소투입의 우려가 없어 균일한 품질의 확보가 용이하며, 부직포를 통과한 지하수 등이 유공철판의 통공을 통하여 유입된 후에 골재의 공극과 플라스틱 유공관의 통과하면서 자연적으로 여과되는 우수한 효과가 있다.The prefabricated double filter blind pit according to the present invention is installed at the lower surface of the ground during construction of a road or a playground, and the aggregate 2 is filled between the round plastic perforated pipe 1 and the outer perforated iron plate 4 and the perforated iron plate. On the outer surface of (4), the nonwoven fabric is attached to make the drainage of water more efficient, and only a certain amount of nonwoven fabric is used, thus preventing the waste of nonwoven fabric that has been involved in the construction of the traditional blind rock, and reducing the required amount of filter aggregates, thus reducing the transportation cost and labor costs. Construction cost is reduced, and there is no fear of excessive or underinjection of aggregates, so it is easy to secure uniform quality, and after the groundwater, which has passed through the non-woven fabric, flows through the perforated steel sheet, There is an excellent effect of naturally filtering as it passes.
