본 발명은 연약지반에 수직으로 삽입 설치되어 토양에 포함된 수분을 배출시키게 되는 드레인보드의 코어재에 관한 것으로, 더욱 상세하게는 드레인보드의 코어재를 각각 양측면에 복수의 돌기부가 돌출 형성되고 돌기부사이에 복수의 통공이 형성되는 판재가 한 조를 이루어 서로 적층되도록 구성하여, 드레인보드가 지반내부에 삽입 설치될 때 코어재의 내부에 형성된 공간부가 드레인보드의 양측면에 가해지는 토압에 의해 함몰되지 않고 원상태로 유지되도록 하므로써, 드레인 보드의 배수성능이 더욱 더 향상되도록 하는 연약지반의 압밀촉진배수용 드레인보드의 코어재에 관한 것이다.The present invention relates to a core material of the drain board that is inserted perpendicular to the soft ground to discharge the moisture contained in the soil, more specifically, a plurality of protrusions protruding formed on both sides of the core material of the drain board and the protrusion The board member is formed so that a plurality of through-holes are formed in a stack so as to be stacked on each other, so that when the drain board is inserted into the ground, the space formed inside the core material is not recessed by the earth pressure applied to both sides of the drain board. The present invention relates to a core material of a drainage board for consolidation and drainage of soft ground, which allows the drainage performance of the drain board to be further improved.

일반적으로 늪지대나 갯벌지대와 같이 토양중에 수분이 많이 포함되어 있는 지대에는 지반이 연약하여 지반상부에 토목구조물이나 건축물 등이 안정되게 건설될 수 없으므로, 이러한 연약지반에 토목공사나 건축공사를 시행하기 위해서는 먼저 연약한 지반을 단단하게 개량시키는 연약지반 개량공사가 선행되어야 할 필요가 있었다.In general, in the areas that contain a lot of moisture in the soil, such as swamps and tidal flats, since the ground is soft, civil structures or buildings cannot be stably built on the ground. First of all, it was necessary to carry out the soft ground improvement work that firmly improves the soft ground.

이와 같이 연약지반을 단단하게 개량시키는 공사에 채용되는 연약지반 개량공법으로서는, 연약지반에 무수히 많은 기둥을 박고 그 기둥의 선단부에 콘크리트구조물을 설치하여 연약지반을 개량하는 방법과, 연약지반에 약액을 주입하여 약액이 굳어지면서 연약지반에 다수의 파일을 형성되어 그들 파일의 선단부에 구조물을 설치하는 방법과, 연약지반에 포함되어 있는 수분을 제거하면서 땅을 다져서 연약지반을 단단하게 하는 방법 등이 있다.In this way, the soft ground improvement method employed in the construction of solid foundations for the soft ground improvement includes a method of improving the soft ground by placing numerous pillars in the soft ground and installing concrete structures at the ends of the pillars. There are a number of piles formed on the soft ground as the chemical liquid hardens by injection, and the structure is installed at the tip of those piles, and the ground is hardened by removing the moisture contained in the soft ground and hardening the soft ground. .

상기와 같은 연약지반 개량공법 중 연약지반에 포함되어 있는 수분을 제거하여 연약지반을 개량하게 되는 공법은, 도 1에 도시되어 있는 바와 같이 연약지반의 내부에 삽입공을 깊게 형성하여 드레인보드(1)를 수직으로 삽입 설치하거나 또는 전용압입장치가 설치된 크레인을 이용하여 드레인보드(1)를 압입시켜 설치하게 되는데, 이 때 연약지반에 포함되어 있던 수분은 수직으로 설치된 드레인보드(1)를 통해 모세관현상에 의해서 지표면으로 상승하게 되며, 이와 같이 지표면으로 상승된 수분은 태양열과 바람에 의해 증발되어 제거되도록 하거나 또는 연약지반의 표면에 도포된 모래층을 통해 지반외부로 배출되도록 하여 제거하므로써, 지반이 자중에 의해 점차 침하되면서 단단하게 다져지도록 한다.The method of improving the soft ground by removing the moisture contained in the soft ground of the soft ground improvement method as described above, as shown in Figure 1 by forming a deep insertion hole in the soft ground drain board (1) ) Is installed vertically or by press-fitting the drain board (1) using a crane equipped with a dedicated press-fitting device. At this time, the moisture contained in the soft ground is capillary tube through the drain board (1) installed vertically. As a result, it rises to the ground by the phenomenon, and the water raised to the ground is removed by being evaporated and removed by solar heat and wind or by being discharged to the outside of the ground through a sand layer applied to the surface of the soft ground. It is gradually settled down so that it can be firmly compacted.

상기와 같은 수분제거를 통하여 지반을 압밀시키는 공법에 사용되고 있는 종래의 드레인보드는 도 2에 도시되어 있는 바와 같이 양측면에 골이 형성되도록 주름지게 형성된 코어재(20)와, 코어재(20)의 외측면을 감싸며 지반내부에 포함된 수분을 흡수하게 되는 필터재(2)로 구성되어 있으며, 이와 같이 구성된 드레인보드 (1)를 지반내부에 수직으로 삽입 설치하게 되면, 토양은 필터재(2)에 걸리게 되고 토양내부에 포함된 수분만이 필터재(2)를 통과하여 필터재(2)와 코어재(20)의 골사이에 형성된 공간부에 저장되며, 이렇게 저장된 수분은 모세관현상에 의해 코어재(20)의 골을 따라 드레인보드(1)의 상단부로 상승하여 지표면으로 배출된다.Conventional drain board used in the method of consolidating the ground through the removal of water as described above is the core material 20 and the core material 20 formed to be corrugated to form a bone on both sides as shown in FIG. It consists of a filter material (2) is wrapped around the outer surface and absorbs the moisture contained in the ground, and when the drain board (1) configured as described above is inserted into the ground vertically, the soil is filter material (2) Only water contained in the soil passes through the filter material 2 and is stored in the space formed between the valleys of the filter material 2 and the core material 20, and the stored water is stored in the core by capillary action. Ascending to the upper end of the drain board 1 along the valley of the ash 20 is discharged to the ground surface.

그러나, 종래의 코어재(20)가 사용되는 드레인보드(1)는 도 3에 도시되어 있는 바와 같이, 지반내부에 수직으로 삽입 설치되어 토양내부에 포함된 수분을 흡수 및 상승시켜 배출하는 과정에서 점차 수분이 배출되어 침하되는 지반에 의해 드레인보드(1)의 양측면으로 강한 토압을 받게 되는데, 이 때 드레인보드(1)의 양측면에 가해지는 강한 토압에 의해서 코어재(20)의 외측면을 감싸는 필터재(2)가 코어재(20)의 골사이로 함몰되어 필터재(2)와 코어재(20)의 골사이에 형성되어 수분이 상승하게 되는 공간부가 현저히 감소하게 되거나 심한 경우에는 필터재(2)와 코어재(20)가 협착되어 막혀버리게 되므로써, 드레인보드(1)의 시공작업후 시간이 경과됨에 따라 드레인보드(1)의 배수성능이 현저히 저하되거나 배수성능을 전혀 발휘할 수 없게 되는 문제점이 있었다.However, as shown in FIG. 3, the drain board 1 using the conventional core material 20 is vertically inserted into the ground to absorb and raise moisture contained in the soil in the process of being discharged. The soil is gradually discharged and receives a strong earth pressure on both sides of the drain board 1 by the ground which is settled. At this time, a strong earth pressure applied to both sides of the drain board 1 surrounds the outer surface of the core material 20. The filter material 2 is recessed between the valleys of the core material 20 and is formed between the valleys of the filter material 2 and the core material 20 so that the space portion where moisture increases is significantly reduced or, in severe cases, the filter material ( 2) and the core material 20 is constricted and clogged, so that the drainage performance of the drainboard 1 is significantly lowered or the drainage performance cannot be exhibited at all as time passes after the construction of the drainboard 1. There was All.
