종래에도 도3과 같이 선박에 설치된 모래탱크(13)내의 모래를 일정한 시간을 두고 벨트콘베이어(14)에 의해 바켓트(15)로 이송시킨후 상기의 바켓트(15)를 포스트(16)의 레일(17)을 따라 상승시켜 윈치(18)에 의하여 상하 이동 가능하게 설치된 공기가압통(1)의 호퍼(2)에 붓고 공기가압통(1)을 통하여 지하에 일정한 깊이로 박은 케이싱파이프(11)내로 모래(12)를 이동시킨 다음 개폐문(3)을 닫고 공기유입관(5)을 통하여 공기가압통로(1)의 내부와 케이싱파이프(11)내에 공기압을 가하여 도1과 같이 케이싱파이프(11)내의 모래(12)를 밀실하게 다져지게 한 후 공기가압통(1)과 케이싱파이프(11)내의 공기압을 감소시키고, 다시 케이싱파이프(11)내에 모래(12)를 유입시키는 작업과 케이싱파이프(11)를 상승시키는 작업을 반복 행하여 도3과 같이 지하에 일정한 간격으로 모래기둥(12')을 시공하는 시공기가 널리 알려져 있으나, 이의 모래기둥시공기의 공기가압통의 개폐문(3)은 실린더등에 의하여 개폐시키게 된 구조로 구성되었으므로 복잡한 구조로 되어 제조비가 많이 소요하면서 작은 고장으로 보수유지비를 많이 요하게됨과 아울러 또한 공기가압통의 공기배출은 다이아프램을 수축 팽창시키는 것에 의하여 통로를 개폐시키게 된 고중량의 고무슬리브로 된 밸브로 된 것이므로 작동이 원활하게 이루어지지 못하면서 고무슬리브가 쉽게 마모될 뿐만 아니라, 고무슬리브가 마모될 때에는 밸브전체를 교체하여야 하게 되어 경제적으로 많은 부담이 따르게 되었다.Conventionally, sand in the sand tank 13 installed in the ship is transferred to the basket 15 by the belt conveyor 14 for a predetermined time as shown in FIG. 3, and then the basket 15 is transferred to the post 16. The casing pipe 11 which is raised along the rail 17 and poured into the hopper 2 of the air pressurization cylinder 1 installed so as to be movable up and down by the winch 18 and which is driven to a predetermined depth underground through the air pressurization cylinder 1 The sand 12 is moved to the inside, and then the opening and closing door 3 is closed, and air pressure is applied to the inside of the air pressure passage 1 and the casing pipe 11 through the air inlet pipe 5, and the casing pipe as shown in FIG. 11) After the sand 12 in the chamber is compactly compacted, the air pressure in the air pressurizing cylinder 1 and the casing pipe 11 is reduced, and the sand 12 is introduced again into the casing pipe 11 and the casing pipe. Repeat the operation of elevating (11) and gather it underground at regular intervals as shown in FIG. Although the construction machine for constructing the pillar 12 'is widely known, the opening and closing door 3 of the air pressurization cylinder of the sand pillar construction machine is composed of a structure that is opened and closed by a cylinder or the like. In addition, it requires a lot of maintenance costs, and also the air discharge of the air pressure cylinder is made of a valve of a heavy weight rubber sleeve that opens and closes the passage by contracting and expanding the diaphragm, so that the rubber sleeve is not easily operated. In addition to wear, when the rubber sleeve is worn out, the entire valve needs to be replaced, resulting in economic burdens.

도1 및 도2에 도시된 바와 같이, 케이싱파이프(11)결합용 프랜지(1')를 형성한 공기가압통(1)의 일측에 호퍼(2)를 고정하여 개폐문(3)을 축(4)으로 유착하고, 공기유입관(5)과 공기배출밸브를 설치하여서 된 것에 있어서, 개폐문(3)은 약간 경사상으로 유착하여 모래(12)의 하강력과 공기유입관(5)의 공기유입력에 의하여 개폐되게 하고, 출구(702)를 형성한 밸브몸체(7)의 입구(701)를 에어실린더(8)의 로드(9)에 고정한 우레탄변판(10)에 의하여 개폐시키게 된 에어밸브(6)에 의하여 공기를 배출시킬 수 있도록함을 특징으로 한 것이다.As shown in Figs. 1 and 2, the hopper 2 is fixed to one side of the air pressurization cylinder 1 in which the flange 1 'for coupling the casing pipe 11 is formed so that the opening / closing door 3 is rotated. In which the air inlet pipe 5 and the air discharge valve are provided, the opening / closing door 3 is slightly inclined so that the descending force of the sand 12 and the air oil of the air inlet pipe 5 An air valve which is opened and closed by an input and is opened and closed by a urethane valve 10 which fixes the inlet 701 of the valve body 7 having the outlet 702 to the rod 9 of the air cylinder 8 ( It is characterized in that the air to be discharged by 6).

미설명부호 12'는 모래기둥이다.Reference numeral 12 'is a pillar of sand.

이와 같은 본 발명은 공기가압통(1)의 프랜지(1')와 결합한 케이싱파이프(11)를 지하에 일정한 깊이로 박은 다음 바켓트(15)에 모래(12)를 담아 상승시켜 호퍼(2)에 쏟으면 모래(12)는 개폐문(3) 및 공기가압통(1)을 통하여 케이싱파이프(11)내로 유입되고 다음 개폐문(3)을 닫음과 동시에 공기유입관(5)을 통하여 공기가압통(1)내에 고압공기를 주입하여 공기압력에 의하여 케이싱파이프(11)내의 모래를 밀실하게 다진 다음 공기가압통(1)내의 공기압을 공기배출밸브를 통하여 외부로 배출시켜 공기가압통(1)내의 공기압을 대기압상태로 감소한 다음, 다시 호퍼(2)에 모래(12)를 투입하고 고압공기로 케이싱파이프(11)내의 모래(12)를 가압하면서 케이싱파이프(11)를 상승시키는 반복작용에 의하여 도3과 같이 연약지반에 일정한 간격으로 모래기둥(12')을 시공하게 되고, 상기의 작동에 의하여 모래기둥(12')을 시공하게 되는 것은 공지인 바, 상기의 작동에 있어서 본 발명의 개폐문(3)은 약간 경사상으로 형성하였으므로 호퍼(2)에 모래(12)가 투입될 시에는 개폐문(3)은 모래(12)의 하강력에 의하여 자동으로 열리고 공기유입관(5)을 통하여 공기가압통(1)에 고압공기가 주입될 시에는 고압공기의 압력에 의하여 자동적으로 닫히게 되므로 구조가 간단하여 쉽게 고장이 발생될 염려가 없으면서 제조비의 절감효과를 기할 수 있고, 또한 공기가압통(1)내의 공기압을 에어밸브(6)에 의하여 외부로 배출시키게 되므로 작동이 매우 원활하게 이루어지게 됨과 아울러 장기사용으로 개폐효율이 떨어질 경우에는 우레탄밸브(10)만을 간단히 교체하면 된다.In the present invention, the casing pipe 11 combined with the flange 1 'of the air pressurizing tube 1 is driven to a predetermined depth in the basement, and then the sand 15 is contained in the basket 15 to raise the hopper 2. When poured into the sand (12) flows into the casing pipe (11) through the opening and closing door (3) and the air pressurizing tube (1) and close the next opening and closing door (3) and at the same time through the air inlet pipe (5) 1) Inject high-pressure air into the chamber to compactly sand the casing pipe 11 by the air pressure, and then discharge the air pressure in the air pressure cylinder 1 to the outside through the air discharge valve, and then press the air pressure in the air pressure cylinder 1 Is reduced to atmospheric pressure, and then sand 12 is introduced into the hopper 2 and the casing pipe 11 is raised by pressurizing the sand 12 in the casing pipe 11 with high pressure air. As shown in the following, the pillars of sand (12 ') are constructed at regular intervals on the soft ground. It is well known that the sand pillar 12 'is constructed by the above operation. In the above operation, since the opening and closing door 3 of the present invention is slightly inclined, sand 12 is introduced into the hopper 2. When the opening and closing door (3) is automatically opened by the descending force of the sand (12) and when the high pressure air is injected into the air pressurizing tube (1) through the air inlet pipe (5) automatically by the pressure of the high pressure air Because it is closed, the structure is simple, so there is no fear of breakdown, and the manufacturing cost can be reduced, and the air pressure in the air pressurizing tube 1 is discharged to the outside by the air valve 6, so the operation is very smooth. In addition, when the opening and closing efficiency decreases with long-term use, only the urethane valve 10 may be simply replaced.

이와 같은 본 발명은 공기가압통(1)의 개폐문(3)을 약간 경사상으로 형성하여 모래(12)의 하강력과 공기유입관(5)를 통하여 공기가압통(1)내로 주입되는 고압공기에 의하여 자동적으로 개폐되게 하였으므로 간단한 구조로 쉽게 고장이 발생되지 않아 수명이 길고 제조비를 절감할 수 있으며, 또한 공기가압통(1)내의 고압공기는 에어밸브(6)에 의하여 외부로 배출시키게 됨으로 작동이 매우 원활하게 이루어지게 됨과 아울러 변판은 마모가 잘 되지 않는 우레탄으로 되어 사용수명이 길고, 장기사용으로 마모될 경우에는 우레탄변판(10)만을 간단히 교체하여 사용할 수 있는 효과가 있다.In the present invention as described above, the opening and closing door 3 of the air pressurizing tube 1 is slightly inclined to form high pressure air injected into the air pressurizing tube 1 through the descending force of the sand 12 and the air inlet pipe 5. Because it is automatically opened and closed by the simple structure, it does not occur easily, so it has a long life and can reduce manufacturing cost. Also, the high pressure air in the air pressurized cylinder 1 is discharged to the outside by the air valve 6. In addition to being made very smoothly, the stool is made of urethane that does not wear well, the service life is long, and when worn for a long time, there is an effect that can be used by simply replacing the urethane stool 10.
