Description

석션 드레인 공법에 사용되는 배수재 연결구{Coupling device for succion drain method}Coupling device for succion drain method

본 발명은 연약지반 개량을 위해 지반에 포함된 간극수를 진공으로 흡출시켜 지반을 개량하는 석션 드레인 공법에 사용되는 배수재를 진공발생장치에 연결하는 연결구에 관한 것이다. 특히 연약지반에 삽입된 다수 개의 배수재와 진공발생장치의 배관에 용이하게 연결할 수 있는 구조를 가진 석션 드레인 공법용에 사용되는 배수재 연결구에 관한 것이다.The present invention relates to a connector for connecting the drain material used in the suction drain method for improving the ground by aspirating the gap water contained in the ground to improve the soft ground to a vacuum generator. In particular, the present invention relates to a drainage connector used for a suction drain method having a structure that can be easily connected to a plurality of drainage materials inserted into a soft ground and a pipe of a vacuum generator.

석션 드레인 공법은 연약지반을 개량하는 공법 중의 하나이다. 특히 지반에 포함된 물(간극수)를 진공으로 흡입하여 제거하는 페이퍼 드레인 공법의 일종이다.The suction drain method is one of the methods for improving the soft ground. In particular, it is a kind of paper drain method for sucking and removing water (gap water) contained in the ground by vacuum.

연약지반 개량 공법에는 샌드 드레인(sand drain) 공법과 페이퍼 드레인(paper drain) 공법으로 대별되는데, 샌드 드레인 공법은 연약지반의 상부에 일정 두께의 모래를 포설하여 단기간의 압밀로 간극수를 상부로 배출시켜 지반을 안정화시키는 것이다. 그리고 이를 발전시켜 연약지반에 모래 파일을 박아 간극수를 배출시키기도 하는데, 함수비가 높은 연약 지반에서 모래 파일이 절단되거나 변형이 발생되고, 시공 속도가 늦고 공사비가 비싼 문제가 있다.The soft ground improvement method is roughly divided into sand drain method and paper drain method. Sand drain method installs a certain thickness of sand on top of the soft ground and discharges the pore water to the upper part by short-term consolidation. It is to stabilize the ground. In addition, the development of this to put the sand pile in the soft ground to discharge the pore water, the sand pile is cut or deformation occurs in the soft ground with a high water content, there is a problem that the construction speed is slow and expensive construction cost.

페이퍼 드레인 공법은 시공이 간단하고, 균일한 지반 안정이 가능하여 많이 사용되는 공법으로, 배수재가 연약지반에 삽입되고, 진공으로 간극수를 흡출하는 방법이다.The paper drain method is a method that is easy to install, uniform ground stability is widely used, drainage material is inserted into the soft ground, and the gap water is sucked out by vacuum.

이와 같은 공법에 사용되는 배수재는 합성수지로 성형된 유연한 골조와, 상기 골조를 둘러싼 필터로 구성된다. 골조에는 간극수가 흐를 수 있는 유로홈이 형성되어 있고, 필터는 모래 등의 지반 구성물의 유입을 막아 간극수만이 통과되어 골조의 유로홈을 따라 지상으로 배출되도록 하는 구조이다.Drainage material used in such a method is composed of a flexible frame molded of synthetic resin, and a filter surrounding the frame. A flow path groove is formed in the frame to allow the gap water to flow, and the filter prevents the inflow of ground components such as sand so that only the pore water passes through and is discharged to the ground along the flow path groove of the frame.

그리고 상기의 배수재는 진공을 발생시키는 진공발생장치와 배관으로 연결되어야 하고, 배수재와 배관의 연결을 위해 연결구가 사용된다. 그리고 지표면으로부터 일정 심도까지는 간극수와 공기가 배수재로 흡입되지 않도록 하는 수직관체가 연결된다. 즉 수직관체는 공기가 통하지 않는 벽체를 가진 관체로서, 연약지반의 상층부에서 공기 또는 간극수가 진공에 의해 흡입될 경우 흡입력이 저하되어 지반 깊이 존재하는 간극수를 흡출하지 못하게 된다. 따라서 이를 방지하기 위하여 지표면으로부터 일정 깊이까지는 수직관체가 설치되고, 수직관체의 하단부에 배수재가 특정 장치에 의해 연결되어 설치되는 구조이다.And the drainage should be connected to the vacuum generating device and the pipe for generating a vacuum, a connector is used for the connection of the drainage and the pipe. And from the ground surface to a certain depth, a vertical pipe is connected so that the pore water and air are not sucked into the drain. In other words, the vertical tube is a tube having a wall through which air does not pass. When the air or the pore water is sucked by the vacuum in the upper layer of the soft ground, the suction force is lowered and the pore water which exists deeply in the ground cannot be sucked out. Therefore, in order to prevent this, a vertical pipe is installed from the ground surface to a predetermined depth, and a drain pipe is connected to a lower end of the vertical pipe by a specific device.

이와 같이 종래의 시공 구조는, 연약지반에 깊숙히 박힌 배수재와, 상기 배수재의 상단에 연결되어 지표면으로부터 일정 깊이로 박힌 수직관체와, 배수재의 상단과 수직관체의 하단을 연결하는 특정 장치와, 상기 수직관체와 진공발생장치의 배관을 연결하는 연결구로 구성된다.As described above, the conventional construction structure includes a drainage material embedded in the soft ground, a vertical pipe connected to an upper end of the drainage material and embedded in a predetermined depth from the ground surface, a specific device connecting the upper end of the drainage material and the lower end of the vertical pipe, and the vertical Consists of a connection between the pipe and the pipe of the vacuum generator.

상기의 종래의 배수재는 수직관체와 연결하기 위한 연결구가 필수적으로 구비되어야 한다. 그러나 연결구의 설치에 의해 배수재를 연약 지반에 삽입할 때 큰 저항으로 작용하여 시공이 어렵고, 배수재의 삽입시에 연결구가 이탈되어 지표면의 공기 및 간극수가 그 틈으로 흡입되어 연약 지반의 내부에 있는 간극수를 흡출하여 제거하지 못하는 문제가 있다. 따라서 수직배관의 연결구조를 없애고, 하나의 배수재에서 종래의 수직배관의 역할을 하는 부분을 형성시키고, 진공발생장치의 배관과 바로 연결할 수 있도록 한 구조가 있다.The conventional drainage is essentially provided with a connector for connecting with the vertical pipe. However, when the drainage is inserted into the soft ground by the installation of the connector, it is difficult to install and the installation is difficult.When the drainage is inserted, the connector is separated and the air and the pore water in the ground surface are sucked into the gap and the gap water in the soft ground is There is a problem that can not be removed by aspiration. Therefore, there is a structure to remove the connection structure of the vertical pipe, to form a part that serves as a conventional vertical pipe in one drain, and to be directly connected to the pipe of the vacuum generator.

따라서 본 발명은 진공발생장치의 배관과 배수재를 바로 직결로 연결할 수 있는 연결구를 제공함에 목적이 있다.Therefore, an object of the present invention is to provide a connector that can directly connect the pipe and the drain of the vacuum generator.

본 발명은 배수재와 진공발생장치의 배관을 연결하는 T형 연결구로서, 배수재에 용이하게 삽입되고, 배관에 용이하게 체결되는 구조를 가진 연결구가 제공된다.The present invention provides a connector having a structure that is easily inserted into the drain, and is easily fastened to the pipe as a T-shaped connector for connecting the pipe of the drain and the vacuum generator.

상기와 같이 배수재와 배관을 간단하고 확실하게 연결할 수 있는 구조를 제공함으로써, 연약지반의 개량 공법이 매우 용이하게 이루어지는 효과가 있다.As described above, by providing a structure in which the drain material and the pipe can be connected simply and reliably, there is an effect that the improvement method of the soft ground is made very easy.

본 발명에 의한 석션 드레인 공법에 사용되는 배수재 연결구(100)는, 일정 길이의 수평관체(1); 상기 수평관체(1)에 수직으로 연결되게 설치되고, 납작한 형상을 가지며, 배수재(50)의 골조(51)가 삽입되는 수직관체(2)로 구성된다.Drainage connector 100 used in the suction drain method according to the present invention, the horizontal pipe (1) of a predetermined length; It is installed vertically connected to the horizontal pipe (1), has a flat shape, and consists of a vertical pipe (2) into which the frame 51 of the drain material 50 is inserted.

그리고 상기 수직관체(2)의 외측면에는 오링(4)이 빙둘러 설치되어 있다.And the outer ring of the vertical tube (2) O-ring (4) is installed roundly.

또한 상기의 수평관체(1)의 양단부에는 체결부(3)가 형성되어, 진공발생장치의 배관(60)에 체결되게 실시할 수 있다. 상기 체결부(3)는 도 2와 도 5에 도시된 바와 같이, 배관(60)이 내부로 삽입된 후 외측 캡을 나사체결하면 배관(60)을 가압하여 고정시키는 일반적인 관연결구의 구조와 같다.In addition, a fastening portion 3 is formed at both ends of the horizontal pipe body 1, and can be implemented to be fastened to the pipe 60 of the vacuum generator. 2 and 5, as shown in Figure 2 and 5, after the pipe 60 is inserted into the inner cap is screwed to the outer cap is the same as the structure of a general pipe connector for pressing and fixing the pipe 60. .

상기와 같은 연결구(100)를 이용하여 배관(60)과 연결되는 배수재(50)의 구조는, 다수 개의 유로홈(52)이 길이 방향으로 형성되고, 일정 폭과 길이를 가진 골조(51)와, 상기 골조(51)의 외측에 부착된 필터(53)로 구성되고, 특히 상기 골조(51)의 일측부에 위치된 필터(53)에 기밀코팅층(54)이 형성된 구조이다.The structure of the drainage material 50 is connected to the pipe 60 by using the connector 100 as described above, the plurality of flow path grooves 52 are formed in the longitudinal direction, the frame 51 having a predetermined width and length and The filter 53 is attached to the outside of the frame 51, and in particular, the airtight coating layer 54 is formed on the filter 53 located at one side of the frame 51.

따라서 본 발명의 연결구(100)의 수직관체(2)의 내부로 배수재(50)의 골조(51)가 삽입되고, 수평관체(1)의 양단에 설치된 체결부(3)에 진공발생장치의 배관(60)이 연결된다.Accordingly, the frame 51 of the drainage material 50 is inserted into the vertical pipe 2 of the connector 100 of the present invention, and the pipe of the vacuum generator is connected to the fastening portion 3 provided at both ends of the horizontal pipe 1. 60 are connected.

본 발명의 사용 실시예가 도 1에 도시되어 있는데, 연약지반에 삽입된 다수 개의 배수재(50)의 상단에 본 발명의 연결구(100)가 설치되고, 상기 연결구(100)에 다시 배관(60)이 연결된 구조이다.An embodiment of the present invention is shown in Figure 1, the connector 100 of the present invention is installed on the upper end of the plurality of drain material 50 inserted into the soft ground, the pipe 60 is again connected to the connector 100 It is a connected structure.

도 2 내지 도 5는 연결구(100)와 배수재(50)가 결합되는 구조를 도시한 것으로, 수직관체(2)가 배수재(50)의 필터(53)와 기밀코팅층(54)이 형성된 내부로 삽입되고, 그 내측의 골조(51)가 수직관체(2)에 삽입되는 구조이다. 그리고 기밀코팅층(54)과 필터(53)의 복합층 부분의 끝단부가 수평관체(1)의 부분까지 다다른 후 가압링(70)에 의해 고정된다.2 to 5 illustrate a structure in which the connector 100 and the drain 50 are coupled to each other, and the vertical tube 2 is inserted into the filter 53 and the airtight coating layer 54 of the drain 50. The inner frame 51 is inserted into the vertical tube 2. And the end of the composite layer part of the airtight coating layer 54 and the filter 53 reaches the part of the horizontal tube 1, and is fixed by the pressure ring 70.

가압링(70)은 도 2에 도시된 바와 같이 배수재(50)의 외부에 끼워져 있는 상태에서, 수직관체(2)가 배수재(50)에 삽입되면, 도 3과 같이 가압링(70)을 수평관체(1) 가까이에 이동시켜 배수재(50)와 수직관체(2)가 기밀되게 접촉시킨다.When the pressure ring 70 is inserted into the drainage material 50 in a state in which the pressure ring 70 is fitted to the outside of the drainage material 50 as shown in FIG. 2, the pressure ring 70 is horizontal as shown in FIG. 3. It moves near the pipe body 1, and the drainage material 50 and the vertical pipe body 2 are hermetically contacted.

상기 상태에서는 도 5에서와 같이 수직관체(2)의 외측에 설치된 오링(4)이 배수재(50)의 내측 필터(53)면에 접촉하게 되어, 그 기밀성이 더욱 향상된다.In this state, as shown in FIG. 5, the O-ring 4 provided on the outer side of the vertical tube 2 comes into contact with the inner filter 53 surface of the drain 50, further improving its airtightness.

상기와 같이 배수재(50)와 배관(60)을 연결하여, 진공발생장치를 이용하여 진공을 발생시키면, 연약지반 내부에 있는 간극수는 배수재(50)로 흡입되고, 골조(51)의 내부 유로홈(52)을 따라 상부로 이동된다.When the drainage material 50 and the pipe 60 are connected as described above, and a vacuum is generated using a vacuum generator, the gap water in the soft ground is sucked into the drainage material 50 and the internal flow path groove of the frame 51 is formed. Is moved upward along 52.

상부로 이동된 간극수는 도 5에 도시된 바와 같이 수직관체(2)로 이동되고, 이어서 수평관체(1)를 통해 소정의 위치로 이동되어 제거된다.The gap number moved upward is moved to the vertical tube 2 as shown in FIG. 5, and then moved to a predetermined position through the horizontal tube 1 and removed.

통상적인 배수재(50)는 얇은 형상으로 되어 있으므로, 골조(51)가 삽입되는 수직관체(2) 또한 평평한 얇은 형상으로 되어 긴밀하게 결합되는 구조가 된다.Since the conventional drainage material 50 has a thin shape, the vertical pipe body 2 into which the frame 51 is inserted also becomes a flat thin shape, thereby becoming a structure that is closely coupled.

그리고 골조(51)와 수직관체(2)의 삽입 결합을 용이하게 하기 위하여, 골 조(51)를 도 5와 같이 뾰족한 형상으로 가공하고, 수직관체(2)의 단부 형상은 좁게 함으로써, 결합시에 용이하게 삽입될 수 있도록 하고, 결합 후에는 간격이 없도록 할 수 있다. 따라서 수직관체(2)와 골조(51)의 결합은 틈없이 아주 긴밀하게 이루어지게 된다.In order to facilitate the insertion coupling of the frame 51 and the vertical tube 2, the frame 51 is processed into a pointed shape as shown in Fig. 5, and the end shape of the vertical tube 2 is narrowed, It can be easily inserted into, and there can be no gap after joining. Therefore, the coupling of the vertical tube 2 and the frame 51 is made very tightly without any gap.

그리고 기밀코팅층(54)과 필터(53)의 복합층 부분은 골조(51)의 단부보다 길게 형성되어 있어, 골조(51)가 그 내부에 위치된 구조가 되도록 함이 바람직하다. 따라서 수직관체(2)와 골조(51)가 결합된 경우에, 기밀코팅층(54)과 필터(53)의 복합층은 수직관체(2)와 골조(51)의 연결부를 덮어주는 구조가 된다.And the airtight coating layer 54 and the composite layer portion of the filter 53 is formed longer than the end of the frame 51, it is preferable to have a structure in which the frame 51 is located therein. Therefore, when the vertical tube 2 and the frame 51 are coupled, the composite layer of the airtight coating layer 54 and the filter 53 has a structure covering the connection portion of the vertical tube 2 and the frame 51.

그리고 복합층 부분은 수직관체(2)를 덮고 그 끝단부는 수평관체(1)부에 다다르게 되는데, 이 때 가압링(70)이 기밀코팅층(54)과 필터(53)의 복합층 부분과 수직관체(2)를 기밀되게 결합시킨다.The composite layer portion covers the vertical tube 2 and its end portion reaches the horizontal tube 1 portion. At this time, the pressure ring 70 has the composite layer portion and the vertical tube of the airtight coating layer 54 and the filter 53. (2) is hermetically combined.

이와 같이 본 발명은 배수재(50)와 배관(60)을 용이하게 연결할 수 있게 된다.As described above, the present invention can easily connect the drain 50 and the pipe 60.
