본 발명은 X형 코어를 구비한 PBD공법의 배수재에 관한 것으로, 보다 상세하게는 PBD 공법을 통해 연약지반에 타설되는 배수재의 코어에 간격유지부재를 형성하여 코어의 변형시에도 코어와 필터의 간격을 유지시켜 줌으로써 배수로의 막힘현상을 방지하여 원활하게 연약지반의 탈수가 이루어지도록 하는 X형 코어를 구비한 PBD공법의 배수재에 관한 것이다.The present invention relates to a drainage material of the PBD method having an X-type core, and more particularly, the gap between the core and the filter even when the core is deformed by forming a gap retaining member in the core of the drainage material placed on the soft ground through the PBD method. The present invention relates to a drainage material of the PBD method having an X-type core for preventing the clogging of the drainage channel and maintaining the dehydration of the soft ground smoothly.

통상 연약지반이라 함은 상부구조물을 지지할 수 없는 상태의 지반을 지칭하는 것으로, 즉 연약지반이라 하더라도 상부구조물을 지지할 수 있느냐의 여부는 그 지반이 받는 하중의 크기에 달려 있는 상대적인 개념이다.In general, the soft ground refers to the ground in a state where the upper structure cannot be supported, that is, whether the soft ground can support the upper structure is a relative concept depending on the magnitude of the load that the ground receives.

상기와 같은 연약지반을 개량하기 위한 공법중의 하나인 PBD(Plastic Board Drain)공법은 도 1 에서와 같이 연약지반(106)의 내부에 삽입공을 형성하여 배수재(100)를 수직으로 삽입설치하거나 또는 전용압입장치가 설치된 크레인을 이용하여 배수재(100)를 압입시켜 설치하며, 상기 연약지반(106)에 포함되어 있는 수분은 수 직으로 설치된 배수재(100)를 통해 지표면으로 상승되어 배출되게 되는 것이다. PBD (Plastic Board Drain) method, which is one of the methods for improving the soft ground as described above, forms an insertion hole in the soft ground 106 as shown in FIG. 1 or vertically inserts and installs the drainage material 100. Alternatively, the drainage 100 is press-fitted and installed using a crane having a dedicated press-fitting device, and the water contained in the soft ground 106 is discharged to the ground surface through the drainage 100 installed vertically. .

상기 배수재는 도 2 및 도 3 에서와 같이 플라스틱 재질의 코어(101)와, 상기 코어(101)를 감싸 이물질의 유입을 방지하는 필터(105)로 구성된다.The drainage material is composed of a plastic core 101, as shown in Figures 2 and 3, and a filter 105 surrounding the core 101 to prevent the inflow of foreign matter.

상기 코어(101)는 플라스틱보드(102)의 양측면에 일정간격으로 이격되는 다수의 칸막이(103)가 수직방향으로 형성되어 칸막이(103)와 칸막(103)이 사이에 배수로(104)가 형성되며, 상기 배수로(104)를 통해 연약지반(106)의 과잉간극수를 지상으로 배수하게 되는 것이다.The core 101 has a plurality of partitions 103 spaced apart at regular intervals on both sides of the plastic board 102 in a vertical direction to form a drainage passage 104 between the partitions 103 and the partitions 103. The excess pore water of the soft ground 106 is drained to the ground through the drainage path 104.

그러나 상기와 같은 구조의 배수재(100)를 연약지반(106)에 타설할 경우 지중의 수직, 수평변형력에 의해 배수재(100) 고유의 편평성을 잃어 휘어짐(bending), 뒤틀림(twisting), 접힘(folding)이 심층부로 갈수록 심하게 발생되어 코어의 배수로 단면이 손상되어 배수성능이 저하되는 문제점이 있다.However, when the drainage material 100 having the structure described above is placed on the soft ground 106, the inherent flatness of the drainage material 100 is lost due to the vertical and horizontal deformation forces of the ground, such as bending, twisting, and folding ( There is a problem in that the folding occurs deeper toward the deeper portion and the cross section is damaged by the drainage of the core and the drainage performance is lowered.

즉 상기 코어가 연약지반 내부에서 발생되는 외력에 의해 변형이 발생되어 배수로(104)가 막혀지게 되고 코어(101)의 외면을 둘러싸는 필터(105)가 코어(101)에 완전히 밀착되어 필터(105)로서의 기능을 수행하지 못함은 물론 배수로(104) 막게 되어 배수성능이 저하되는 문제점이 있다.That is, the core is deformed by the external force generated in the soft ground, so that the drainage passage 104 is blocked, and the filter 105 surrounding the outer surface of the core 101 is completely in close contact with the core 101 to filter 105 Of course, there is a problem in that the drainage performance is lowered as the drainage 104 is blocked, as well as not performing the function.

The branch has a corrugated structure.

상기 플라스틱 보드(21)의 강도유지 및 뛰어난 통수기능을 가질 수 있도록 상기 제1경사부재(22) 및 제2경사부재(23)가 연결되는 연결각도는 40~90°의 각도를 가진다.The connection angle between the first inclined member 22 and the second inclined member 23 may have an angle of 40 ° to 90 ° to maintain the strength of the plastic board 21 and to have an excellent water supply function.

상기와 같은 실시예에 의한 본 발명의 코어(20)는 그 단면의 형상이 X형태로 구성되어 있음으로 인해 압밀이나 측압에 의해 정점부(26)가 눌려진다 하더라도 간격유지부재(24)가 수직하게 세워짐으로써 필터(30)가 코어(20)로 밀착되어 배수로(25)를 막게 되는 현상을 방지함은 물론 필터(30)를 외측으로 밀어주어 보다 넓은 배수로(25)가 제공되는 것이다.In the core 20 of the present invention according to the embodiment described above, even if the vertex portion 26 is pressed by consolidation or side pressure due to the shape of the cross section of the X shape, the space keeping member 24 is vertical. By standing so as to prevent the phenomenon that the filter 30 is in close contact with the core 20 to block the drainage passage 25, as well as to push the filter 30 to the outside to provide a wider drainage passage 25.

상기와 같은 실시예에 의해 본 발명의 배수재(10)를 지중에 삽입할 경우 지중에서 발생되는 압밀이나 측압에 의해 필터(30)가 코어(20)로 밀착될 경우 간격유지부재(24)에 의해 배수로(25)의 막힘 현상이 방지되는 것을 도 8 을 통해 보다 상 세히 설명하면 다음과 같다.When the drainage material 10 of the present invention is inserted into the ground according to the embodiment as described above, when the filter 30 is in close contact with the core 20 due to consolidation or lateral pressure generated in the ground, the gap holding member 24 is used. The blocking phenomenon of the drainage passage 25 will be described in more detail with reference to FIG. 8 as follows.

본 발명의 배수재(10)를 지중에 타설하면 도면에서와 같이 압밀과 측압에 의해 상기 플라스틱보드(21)의 제1경사부재(22)와 제2경사부재(23)가 연결되는 연결부, 즉 산과 골의 정점부(26)가 눌려지게 되고 이로 인해 상기 제1경사부재(22) 및 2경사부재(23)의 연결각이 커지게 되어 플라스틱보드(21)가 수평하게 펼쳐지게 됨으로써 코어(20)와 필터(30)와의 간격이 가까워지게 된다.When the drainage material 10 of the present invention is placed in the ground, as shown in the drawing, the connecting portion, that is, the mountain and the connecting portion, in which the first inclined member 22 and the second inclined member 23 of the plastic board 21 are connected by consolidation and side pressure. The apex 26 of the bone is pressed and the connection angle between the first inclined member 22 and the second inclined member 23 is increased so that the plastic board 21 is spread out horizontally so that the core 20 and The distance from the filter 30 becomes close.

그러나 이때 경사지게 형성되어 있는 간격유지부재(24)가 제1경사부재(22) 및 제2경사부재(23)의 수평변형에 의해 수직방향으로 세워지게 됨으로써, 코어(20)로 밀착되는 필터(30)를 받쳐주어 코어(20)와 필터(30)와의 간격을 일정하게 유지시킴으로써 배수로(25)의 막힘을 방지하여 원활한 배수가 가능하게 되는 것이다.However, at this time, the interval maintaining member 24 formed to be inclined is erected in the vertical direction by the horizontal deformation of the first inclined member 22 and the second inclined member 23, so that the filter 30 is in close contact with the core 20. ) To maintain a constant distance between the core 20 and the filter 30 to prevent clogging of the drainage passage 25 to enable smooth drainage.

즉 압밀이나 측압이 발생하면 간격유지부재(24)에 의해 필터(30)가 더 팽팽해져 배수로(25)의 막힘을 방지하게 되는 것이다.That is, when consolidation or side pressure occurs, the filter 30 is further tightened by the gap holding member 24 to prevent the drainage passage 25 from being blocked.

또한 상기 간격유지부재(24)에 의해 코어(20)가 변형되지 않고 부직포 재질의 필터(30)가 늘어나 코어(20)로 밀착될 경우에도 상기 간격유지부재(24)에 필터(30)가 걸려져 코어(20)로 더 이상 밀착되지 않도록 함으로써 배수로(25)가 막혀지는 현상을 방지하게 된다.In addition, even if the core 20 is not deformed by the spacing member 24 and the filter 30 of the nonwoven material is extended and closely adhered to the core 20, the filter 30 is caught by the spacing member 24. By preventing it from being in close contact with the jersey core 20, the phenomenon in which the drainage passage 25 is blocked is prevented.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

상기와 같은 구성 및 작용에 의해 기대할 수 있는 본 발명의 효과는, 압밀이나 측압에 의해 배수재의 플라스틱 보드가 변형될 경우에는 간격유지부재에 의해 코어와 필터의 간격을 유지시켜 줌으로써 필터의 밀착에 의한 배수로의 막힘현상을 방지함은 물론 제1경사부재와 제2경사부재의 연결각이 벌어짐으로써 더 넓은 배수로를 구비하게 되어 중의 간극수가 배수로를 통해 원활하게 지상으로 배수되도록 하는 매우 유용한 발명이다.The effect of the present invention, which can be expected by the above-described configuration and action, is to maintain the gap between the core and the filter by the gap retaining member when the plastic board of the drain material is deformed due to consolidation or lateral pressure. It is a very useful invention to prevent the clogging phenomenon of the drainage passage as well as the connection angle between the first inclined member and the second inclined member to have a wider drainage passage so that the gap water in the drainage can be smoothly drained to the ground through the drainage passage.
