Description

지반 굴착용 흙막이 말뚝{Pile for retaining System}Ground Excavation Pile {Pile for retaining System}

본 발명은 지반 굴착용 흙막이 말뚝에 관한 것이다.The present invention relates to a ground piling pile.

첨부 도면중 도 1a,1b는 종래 흙막이 공법의 시공예를 나타내는 개략도면이다.1A and 1B of the accompanying drawings are schematic diagrams showing a construction example of a conventional soil film construction method.

이 도면들에서 도시하는 바와 같이 지하수가 있는 상태에서 지반을 굴착하는 경우 지하수를 양수하는 데는 두 가지 방법이 사용된다.As shown in these figures, two methods are used to pump groundwater when excavating the ground in the presence of groundwater.

하나는 굴착부 바닥에 섬프를 형성하고 여기에 고인물을 펌프를 사용하여 양수하는 방법으로서 공사비는 저렴하나 흙막이 벽체를 통해서 지하수가 흐르게 되어 토사가 유출되고 바닥이 포화되어 굴착작업이 곤란하게 된다.One is to form a sump at the bottom of the excavation part and pump the deceased here using a pump. The construction cost is inexpensive, but the groundwater flows through the wall of the earth, so that the soil is leaked and the floor is saturated, making the excavation work difficult.

다른 하나는 흙막이 배면에 양수공을 설치하고 수중펌프를 삽입하여 양수하는 방법으로서 바닥에 자유수가 없으므로 굴착작업은 용이하나 공사비가 비싸The other method is to install a pumping hole on the back of the earthen board and insert a water pump to pump the pump.

지게 되는 단점이 있다.There is a disadvantage to losing.

상기와 같은 단점으로 인하여 별도의 섬프나 양수공을 설치하지 아니하고 굴 착부의 바닥에 자유수가 생기지 아니하는 저렴한 양수방법이 필요하게 되었다.Due to the drawbacks described above, there is a need for an inexpensive pumping method in which free water does not occur at the bottom of the excavation without installing a separate sump or pumping hole.

상기의 필요성에 따라 본 발명에서는 굴착을 위해 설치하는 흙막이의 엄지말뚝(이하, 말뚝 혹은 엄지말뚝이라 함)에 양수기능을 추가한 저렴하고 효율적인 흙막이 말뚝을 제공하는 데에 그 목적이 있다.In accordance with the necessity of the above, the present invention has an object to provide an inexpensive and efficient mudstone pile having a pumping function added to the thumb pile (hereinafter referred to as a pile or thumb pile) of the mudstone for excavation.

상기 목적을 달성하기 위한 본 발명 지반 굴착용 흙막이 말뚝은,Soil excavation pile for the present invention for achieving the above object,

말뚝본체와, 상기 말뚝본체의 플랜지 내측에 공간을 형성하는 보호대를 포함하는 흙막이 말뚝에 의하여 달성된다.The soil film including a pile body and a guard forming a space inside the flange of the pile body is achieved by the pile.

상기 목적을 달성하기 위한 본 발명 지반 굴착용 흙막이 말뚝은 H형 형강이거나, ㄷ 형강이다.Ground excavation piling pile of the present invention for achieving the above object is H-shaped steel or c-shaped steel.

상기 목적을 달성하기 위한 본 발명 지반 굴착용 흙막이 말뚝의 상기 보호대는 ㄴ형 단면을 이루거나, 혹은 상기 보호대가 원통형 파이프로 함이 바람직하다. The guard of the earth excavation piling pile of the present invention for achieving the above object is preferably a b-shaped cross section, or the guard is preferably a cylindrical pipe.

상기 목적을 달성하기 위한 본 발명 지반 굴착용 흙막이 말뚝의 상기 보호대는 물이 침투할 수 있는 미세공을 다수 형성함이 바람직하다.The guard of the earth excavation piling pile of the present invention for achieving the above object is preferably to form a plurality of micropores that can penetrate the water.

본 발명은 굴착을 위해 설치하는 흙막이의 말뚝에 양수기능을 갖는 보호대를 형성하여 지반 굴착시 흙막이 말뚝을 통하여 지하수를 능률적으로 양수하게 되는 효과를 얻는다.The present invention forms the guard having a pumping function in the pile of the earthquake to be installed for excavation to obtain the effect of efficiently pumping groundwater through the earthquake pile during the ground excavation.

본 발명으로 인하여 굴착의 모든 단계에서 바닥에 자유수가 생기지 아니하여 Dry Work가 가능하게 되므로 굴착작업이 용이하며 별도의 양수공이나 값비싼 수중 펌프를 사용하지 아니하므로 공사비가 저렴하게 되는 장점이 있다.Due to the present invention, dry work is possible because free water does not occur at the bottom of the excavation at all stages of the excavation, and thus the excavation work is easy, and there is an advantage that the construction cost is low because no separate pump or expensive submersible pump is used.

이하, 본 발명의 바람직한 실시예를 첨부한 도면들과 함께 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

첨부 도면중 도 2a,2b,2c는 본 발명 지반 굴착용 흙막이 말뚝의 구조를 나타내는 단면도이고, 도 3a,3b는 본 발명 지반 굴착용 흙막이 말뚝의 보호대의 발췌도면이다.Figures 2a, 2b, 2c is a cross-sectional view showing the structure of the earth excavation piling pile of the present invention, Figure 3a, 3b is an excerpt view of the guard of the earth excavation piling pile of the present invention.

상기 도면에서 도시하는 바와 같이 본 발명은 말뚝본체(10)(11)와, 상기 말뚝본체(10)(11)의 플랜지 내측에 공간(23)을 형성하도록 부착된 보호대(20)로 이루어진다. 상기 말뚝은 H형 형강 혹은 ㄷ 형강으로 이루어지며, 그외에 여러가지 단면의 구조로도 적용가능하다.As shown in the figure, the present invention includes a pile body 10 and 11 and a guard 20 attached to form a space 23 inside the flange of the pile body 10 and 11. The pile is made of H-shaped steel or c-shaped steel, and can be applied to other cross-sectional structures.

상기 보호대(20)는 ㄴ형,ㅁ형,ㄷ형등 여러형태 단면으로 플랜지내에 형성되며, 다수의 미세공(201)을 형성하여서 된다. The guard 20 is formed in the flange in a variety of cross-sections, such as b-shaped, ㅁ -shaped, c-shaped, it is to form a plurality of fine holes 201.

또한, 상기 보호대(20)는 원통형의 파이프(21)로 이루어지기도 한다.이 보호대(21)에는 물이 침투할 수 있는 다수의 미세공(211)을 형성하여서 된다.In addition, the guard 20 may be made of a cylindrical pipe 21. The guard 21 may be formed by forming a plurality of micropores 211 through which water can penetrate.

첨부 도면 도 4는 본 발명 지반 굴착용 흙막이 말뚝들의 요부를 확대한 횡단면을 나타내고, 도 5a,5b는 본 발명 지반 굴착용 흙막이 말뚝들과 토류판이 설치된 상태의 지반 굴착면의 횡단면을 나타낸다. 도 6은 본 발명 지반 굴착용 흙막이 말뚝을 통하여 지하수를 양수하는 방법을 도시하는 개략적인 횡단면도이고,도 7a,7b는 본 발명 지반 굴착용 흙막이 말뚝을 통하여 지하수를 단계별로 양수하는 방법을 나타내는 도면들이다. 4 is a cross-sectional view showing an enlarged main portion of the ground excavation piling piles of the present invention, Figures 5a, 5b is a cross-sectional view of the ground excavation surface of the ground drilling piling piles and the earth plate of the present invention is installed. Figure 6 is a schematic cross-sectional view showing a method of pumping groundwater through the ground excavation piling pile of the present invention, Figure 7a, 7b is a view showing a method of pumping groundwater step by step through the ground excavation piling pile of the present invention. .

상기 도면들에서 보는 바와 같이 이와 같이 이루어진 본 발명 지반 굴착용 흙막이용 말뚝은 먼저 지반에 천공하여 연직의 구멍을 형성한 후에 상기의 말뚝을 삽입하고 구멍의 빈 공간을 모래로 되메우게 된다. As shown in the drawings, the ground excavation piling pile of the present invention made as described above is first drilled in the ground to form a vertical hole, and then inserting the pile and filling the empty space of the hole with sand.

본 발명에서 상기 말뚝본체의 플랜지 내측에 보호대가 설치되어 있고, 되메움시 모래가 침입할 수 없는 공간(23)이 형성되어 있다.In the present invention, a guard is provided inside the flange of the pile body, and a space 23 is formed in which sand cannot penetrate during backfilling.

상기 보호대(20)(21)는 말뚝본체(10)(11)의 길이방향으로 설치하되 용접등의 수단으로 말뚝본체(10)(11)와 결합시킨다. The guards 20 and 21 are installed in the longitudinal direction of the pile body 10 and 11, but are coupled to the pile body 10 and 11 by means of welding or the like.

전술한 바와 같이 보호대(20)(21)에는 지하수가 쉽게 침입할 수 있도록 미세공(201)(211)을 다수 형성하므로 되메움된 모래로 부터 지하수가 침투된다.As described above, the guards 20 and 21 form a plurality of micropores 201 and 211 so that the groundwater can easily invade the groundwater from the backfilled sand.

첨부 도면중 도 6은 본 발명 지반 굴착용 흙막이 말뚝을 통하여 지하수를 양수하는 방법을 도시하는 개략적인 횡단면도이고,도 7a,7b는 본 발명 지반 굴착용 흙막이 말뚝을 통하여 지하수를 단계별로 양수하는 방법을 나타내는 도면들이다.6 is a schematic cross-sectional view showing a method of pumping groundwater through the ground excavation piling pile of the present invention, Figure 7a, 7b is a method for pumping groundwater step by step through the ground excavation piling pile of the present invention It is a figure which shows.

상기와 같이 보호대(20)(21)를 형성한 말뚝본체(10)(11)는 미리 천공한 구멍에 매입하고 구멍속의 공간을 모래로 되메움하므로써 모래가 토립자의 침투를 막고 지하수를 통과시키는 필터의 역할을 하게 된다.The pile body 10 and 11 having the guards 20 and 21 formed as described above are embedded in a previously drilled hole and fill the space in the hole with sand so that the sand prevents the infiltration of the granules and passes the groundwater. It will play the role of.

즉, 보호대(20)(21)의 내측은 필터기능의 모래로 보호된 공간(23)이 형성되어 있다. 굴착작업이 진행되면 말뚝본체(10)(11)의 플랜지가 노출되고 여기에 토류판(50)을 설치하게 되며, 이때 보호대(20)(21)도 노출된다.That is, inside the guard 20, 21, the space 23 protected by the sand of a filter function is formed. When the excavation work is carried out, the flange of the pile body 10, 11 is exposed and the earth plate 50 is installed there, and the guard 20, 21 is also exposed.

노출된 보호대(20)(21)의 측면에 호스가 삽입될 만한 크기의 구멍을 뚫고 이 구멍을 통하여 호스를 삽입한다. 상기의 구멍은 보호대 설치시에 미리 형성하고 마개로 막아 두었다가 말뚝이 노출된 후 마개를 제거하는 방식으로 만들 수 있다.Drill a hole in the side of the exposed guard 20, 21 to the size that the hose is inserted and insert the hose through the hole. The above holes can be made in advance by forming the guards, plugging them in the caps and removing the plugs after the piles are exposed.

상기 구멍으로 삽입한 호스는 보호된 공간을 따라 연직으로 내려 보내어 지하수위 아래까지 이르게 한다.The hose inserted into the hole is sent down vertically along the protected space to reach below the groundwater level.

이 상태에서 흡인펌프를 호스에 연결하여 지하수를 양수함으로써 지하수위를 하강시킨다. 상기의 흡인펌프는 가격이 저렴하여 다수를 설치할 수 있는 장점이 있다. 흡인펌프의 양정은 실용적으로 6~8미터이므로 굴착이 진행되면 굴착부의 바닥에 자유수가 출현하게 된다.새로이 노출된 보호대에 두번째 구멍을 뚫고 호스를 이설하여 양수함으로써 재차 지하수위를 하강시키고 이하 같은 공정을 반복한다.In this state, the ground water level is lowered by connecting the suction pump to the hose and pumping the ground water. The suction pump has the advantage that can be installed a large number because the price is low. Since the suction head of the suction pump is practically 6 to 8 meters, free water will appear at the bottom of the excavation section when the excavation is progressed.The groundwater level is lowered again by drilling a second hole and relocating the hose to the newly exposed guard. Repeat.
