Description

지반보강재 및 그 생산방법{GROUND REINFORCEMENT DEVICE AND THE MANUFACTURING METHOD THEREOF}Ground reinforcement and its production method {GROUND REINFORCEMENT DEVICE AND THE MANUFACTURING METHOD THEREOF}

본 발명은 지반보강재 및 그 생산방법에 관한 것으로, 더욱 상세하게는 지반 속의 수분을 배출하기 위하여 부직포가 초음파 또는 고주파에 의하여 접합된 지반보강재 및 그 생산방법에 관한 것이다.The present invention relates to a ground reinforcement and a production method thereof, and more particularly, to a ground reinforcing material bonded to the non-woven fabric by ultrasonic or high frequency in order to discharge the moisture in the ground and a production method thereof.

흙 자체는 고체이지만 강철 또는 콘크리트와 같은 결정체가 아닌 불연속체로서 쉽게 분리되며 외력에 의해 쉽게 변이가 일어난다. 특히 모재질 흙은 내부 마찰각은 크나 점착력이 없고 점토는 그 정반대의 경우이다. 따라서 흙 재료의 이용도를 배가시키기 위하여 내부 마찰각과 점착력이 동시에 큰 이상적인 흙 재료가 필요하다.The soil itself is solid but easily separated as a discontinuity rather than a crystal such as steel or concrete, and is easily shifted by external forces. In particular, the base soil has a large internal friction angle but no cohesion and clay is the opposite. Therefore, in order to double the utilization of the soil material, an ideal soil material having a large internal friction angle and cohesion force is needed.

상기의 요구를 충족시키는 새로운 흙 즉 보강토를 만들기 위하여 성토시 흙 다짐층에 판상, Wire상, 망상, 대상 등의 강재 또는 합섬섬유 재질의 지반보강재를 삽입한다. 따라서 지반보강재와 토립자 간의 마찰력에 의한 횡방향 변위를 구속함으로써 소위 겉보기 점착력을 유발하여 보강토를 만든다.In order to make a new soil that meets the above requirements, the reinforcement soil is inserted into the soil compaction layer, such as plate, wire, reticulated, object such as steel or synthetic fiber reinforced ground material. Therefore, by restraining the lateral displacement caused by the frictional force between the ground reinforcement and the granules, the so-called apparent adhesive force is induced to make the reinforcement soil.

도 4는 종래의 지반보강재의 일실시예이다. 도 4에 도시된 지반보강재(5)는 강화섬유 플라스틱 재료로 된 지반보강재로써, 몸체부(6)와 코어부(7)로 구성된다. 몸체부(6)는 저밀도 폴리에틸렌(LDPE), 고밀도 폴리에틸렌(HDPE), PVC, 폴리프로필렌 등으로 형성되며, 코어부(7)는 폴리에스테르 원사, 나일론, 폴리프로필렌 등으로 형성된다.Figure 4 is an embodiment of a conventional ground reinforcement. The ground reinforcement 5 shown in FIG. 4 is a ground reinforcement made of a reinforced fiber plastic material, and is composed of a body portion 6 and a core portion 7. The body portion 6 is formed of low density polyethylene (LDPE), high density polyethylene (HDPE), PVC, polypropylene, and the like, and the core portion 7 is formed of polyester yarn, nylon, polypropylene, or the like.

도 5 및 도 6은 도 4의 지반보강재를 사용하여 아파트 등의 옹벽을 시공하는 개념도이다. 옹벽을 설치하기 위하여 콘크리트 판넬(1)을 타설한다. 다음으로 지반을 형성할 흙(4a)을 채운 후 중장비 등을 사용하여 다짐을 한다. 지반보강재(3)를 콘크리트 판넬(1)과 미리 설치한 장착철근(2)에 연결한다. 다음으로 지반을 형성할 다른 흙(4b)을 채운 후 중장비 등을 사용하여 다짐을 한다.5 and 6 is a conceptual view of the construction of the retaining wall, such as an apartment using the ground reinforcement of FIG. In order to install the retaining wall, the concrete panel (1) is poured. Next, after filling the soil (4a) to form the ground to compact using heavy equipment and the like. The ground reinforcement (3) is connected to the concrete panel (1) and the pre-installed mounting rebar (2). Next, after filling the other soil (4b) to form the ground and compacted using heavy equipment.

대규모의 토지조성이나 도로, 철도, 터널 공사 등으로 인해 생성된 지반은 우수나 융설수가 침투할 경우 지반의 강도가 저하된다. 종래의 지반보강재는 지반 속에 침투된 수분을 배출시키지 못한다. 따라서 수분이 침투될 경우 강도가 저하되고 풍화가 진행됨에 따라 국부적인 사면붕괴나 토사유출 또는 낙석이 발생하여 인명이나 재산상의 피해가 발생한다는 문제점이 있었다.Soils produced by large-scale land construction, roads, railroads, tunnels, etc. are degraded when rainwater or snow melt infiltrates. Conventional ground reinforcement does not discharge the moisture penetrated into the ground. Therefore, when moisture is infiltrated, the strength decreases and weathering progresses, causing local slope collapse, soil leakage, or falling rocks.

본 발명의 일 실시예는 본 발명의 기술적 사상을 한정하는 것으로 해석되어서는 안 된다. 본 발명의 보호범위는 청구범위에 기재된 사항에 의하여만 제한되고, 본 발명의 기술분야에서 통상의 지식을 가진 자는 본 발명의 기술적 사상을 다양한 형태로 개량 변경하는 것이 가능하다. 따라서 이러한 개량 및 변경은 통상의 지식을 가진 자에게 자명한 것인 한 본 발명의 보호범위에 속하게 될 것이다.An embodiment of the present invention should not be construed as limiting the technical idea of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms. Therefore, such improvements and modifications will fall within the protection scope of the present invention, as will be apparent to those skilled in the art.

도 1은 본 발명에 따른 지반보강재의 일 실시예의 사시도이다. 도 1에 따른 지반보강재는 지반보강수단(60)과, 부직포(68)를 포함한다.1 is a perspective view of one embodiment of a ground reinforcement according to the present invention. Ground reinforcement according to Figure 1 includes a ground reinforcing means 60, and a nonwoven fabric (68).

지반보강수단(60)은 몸체부(61) 및 코어부(65)를 구비한다. 코어부(65)는 몸체부(61)의 내부에 삽입된다. 그리고 몸체부(61)의 일면에는 지반 속에 함유된 수분을 배출하기 위한 다수의 채널(63)이 형성된다. 부직포(68)는 채널(63)이 형성된 몸체부(61)의 일면에 고정된다. 이때 고주파 또는 초음파를 사용하여 부직포(68)의 양단(68a, 68c) 및 중앙부(68b) 등 최소한 3곳을 몸체부(61)에 고정시킨다. 부직포(68)가 몸체부(61)에 고정되지 아니한 경우에는 부직포(68)가 몸체부(61)에 대하여 상대운동을 하여 수명이 줄어들 수 있으나, 본 실시예에서 부직포(68)를 몸체부(61)에 고정시킴으로써 지반보강재의 수명을 늘 일 수 있다. 그리고 부직포(68)는 수분을 투과시키지만, 흙을 투과시키지 아니한다. 그러므로 상기 지반보강재가 지반에 설치되면 흙속의 수분만 부직포(68)를 통과하여 채널(63)로 모여서 채널(63)을 따라 외부로 배출된다. The ground reinforcing means 60 has a body portion 61 and a core portion 65. The core portion 65 is inserted inside the body portion 61. And one surface of the body portion 61 is formed with a plurality of channels 63 for discharging the moisture contained in the ground. The nonwoven fabric 68 is fixed to one surface of the body portion 61 in which the channel 63 is formed. At this time, at least three places such as both ends 68a and 68c and the central portion 68b of the nonwoven fabric 68 are fixed to the body portion 61 using high frequency or ultrasonic waves. When the nonwoven fabric 68 is not fixed to the body portion 61, the nonwoven fabric 68 may reduce relative life by moving relative to the body portion 61. However, in this embodiment, the nonwoven fabric 68 may be replaced with a body portion. 61) can increase the life of the ground reinforcement. The nonwoven fabric 68 transmits moisture, but does not transmit soil. Therefore, when the ground reinforcement is installed on the ground, only the moisture in the soil passes through the nonwoven fabric 68 to be collected in the channel 63 and discharged to the outside along the channel 63.

도 2는 본 발명에 따른 지반보강재의 다른 실시예의 사시도이다. 도 1에 도시된 지반보강재는 채널(63)이 몸체부(61)의 일면에 형성되었다. 그러나 도 2에 도시된 지반보강재는 채널(73)이 몸체부(71)의 일면 및 타면에 형성된다. 그리고 부직포(78)도 몸체부(71)의 일면 및 타면에 초음파 또는 고주파로 접합되었다. 코어부(75) 및 부직포(78)의 접합부(78a, 78b, 78c)는 도 1의 실시예와 동일하다.2 is a perspective view of another embodiment of a ground reinforcement according to the present invention. In the ground reinforcement illustrated in FIG. 1, a channel 63 is formed on one surface of the body portion 61. However, in the ground reinforcement illustrated in FIG. 2, the channel 73 is formed on one side and the other side of the body portion 71. The nonwoven fabric 78 was also bonded to one surface and the other surface of the body portion 71 by ultrasonic or high frequency. The junction portions 78a, 78b, 78c of the core portion 75 and the nonwoven fabric 78 are the same as in the embodiment of FIG.

In the core part forming step (S10), a polyester yarn, nylon, polypropylene, and the like are extracted and combined to form the core part 65. Body portion forming step (S20) by extruding low density polyethylene (LDPE), high density polyethylene (HDPE), PVC, polypropylene, etc. to coat the core portion 65 and then cooled to form a body portion. Channel forming step (S30) forms a channel on one surface of the body portion. At this time, the channel may be formed on the other surface of the body portion. And non-woven fabric bonding step (S40) is bonded to the non-woven fabric at least three places on one surface of the body using ultrasonic waves or high frequency. Of course, if the channel is formed on the other side of the body portion is bonded to the non-woven fabric on the other side of the body portion.
