These flotation facilities are fixed in such a way that the moorings settled on the seabed or on the sea floor and the flotation facilities are bound by mooring lines.

또한, 수중 공사시 해저면 또는 하상에 설치되어 수중 지반의 불필요한 부상 및 교란을 억제하고 세굴을 방지하는 매트 및 판체 등 침설물의 고정에도 전술한 중량물이 사용된다.In addition, the above-mentioned heavy materials are used for fixing sediments, such as mats and plates, which are installed on the sea floor or on the bottom during underwater construction to suppress unnecessary injuries and disturbances of the underwater ground and prevent scouring.

수중 공사용 중량물은 금속 또는 콘크리트로 제작될 수도 있으나, 낭체형 합성수지제 본체(10)에 토사 또는 쇄석 등의 충전재(19)가 충전되는 톤백을 적용함으로써, 중량물의 제작비용 절감은 물론 보관 및 운송편의성 등 다양한 이점을 얻을 수 있으며, 이렇듯 수중 공사용 중량물로서 활용되는 톤백 관련 종래기술로는 특허 제617898호 및 특허 제918308호를 들 수 있다.Underwater construction heavy weight may be made of metal or concrete, but by applying a tone bag filled with a filler 19, such as soil or crushed stone, to the bag-shaped synthetic resin body 10, the production cost of the heavy weight, as well as the convenience of storage and transportation Various advantages can be obtained, and the related arts related to the tone bag utilized as a heavy product for underwater construction include Patent Nos. 617898 and Patent 918308.

수중 공사에 사용되는 건설용 톤백(ton-bag)은 합성수지 시트 등으로 봉제된 대형 낭체로서, 현장에서 토사 또는 쇄석 등을 투입, 충전한 후 밀봉하여 중량물로서 활용하게 되는 바, 금속추 또는 콘크리트괴 등 여타의 중량물에 비하여 제작비용이 저렴할 뿐 아니라, 현장에서 중량을 탄력적으로 조절할 수 있는 장점도 있다.
A ton-bag for construction used in underwater construction is a large bag sewn with synthetic resin sheets, etc., which is used as a heavy material by putting and filling soil, crushed stone, etc. in the field, and then using it as a weight. Compared to other heavy materials, such as manufacturing cost is low, and also has the advantage of elastically adjustable weight in the field.

수중 공사용 톤백은 톤백 본체(10)에 토사 등의 충전재(19)를 충전하고 밀봉한 상태로 결속선(13)을 연결하여 수중에 투하하게 되는데, 공사의 종료 또는 시설물의 이동 시 톤백의 회수가 필요한 경우 결속선(13)에 부표(92)를 연결하여 추후 톤백의 위치를 파악할 수 있도록 하는 것이 일반적이다.Tone bags for underwater construction are dropped into the water by connecting the bundling line 13 in a state of filling and sealing the filler 19 such as earth and sand to the tone bag main body 10, the recovery of the tone bag at the end of construction or moving the facility If necessary, it is common to connect the buoy 92 to the binding line 13 so that the position of the toneback can be determined later.

한편, 도 4에서와 같이, 톤백 본체(10)에 열선(20)을 설치함에 있어서, 다수의 만곡부가 연속적으로 반복 형성된 파형(波形) 열선(20)을 적용함으로써, 톤백의 충전 및 투하 과정에서 톤백 본체(10)가 충전재(19)의 하중으로 인하여 팽창되거나, 해류, 파랑 또는 부력으로 인한 변형되는 경우 발생될 수 있는 열선(20)의 파단을 억제할 수 있다.On the other hand, as shown in Figure 4, in installing the heating wire 20 to the toneback body 10, by applying a waveform heating wire 20 formed with a plurality of curved portions continuously, in the charging and dropping process of the toneback It is possible to suppress the breakage of the heating wire 20, which may occur when the toneback body 10 is expanded due to the load of the filler 19 or is deformed due to currents, waves, or buoyancy.

즉, 도 4의 발췌 확대부에서와 같이, 본체(10)가 신장 및 수축됨에 따라 본체(10)에 부착된 열선(20)의 만곡부 곡률이 변화하면서, 본체(10)와 열선(20)이 동반 신축될 수 있도록 한 것이다.That is, as in the expanded portion of FIG. 4, as the main body 10 is extended and contracted, the curvature of the curved portion of the hot wire 20 attached to the main body 10 changes, so that the main body 10 and the hot wire 20 are changed. It is intended to be accompanied by new construction.

이렇듯, 톤백 본체(10)에 밀착 설치된 열선(20)은 전원(29) 인가시 가열되어 합성수지제 톤백을 용융, 절단하게 되며, 이로써 수중에 설치된 톤백에 잠수부가 접근하지 않고도 선상 또는 지상 등 원격지에서의 간편한 조작만으로 톤백 본체(10)의 절단이 가능한 것이다.As such, the heating wire 20 installed in close contact with the tone bag main body 10 is heated when the power supply 29 is applied to melt and cut the tone bag made of synthetic resin, thereby allowing the diver to access the tone bag installed in the water at a remote place such as onboard or on the ground. The simple operation of the toneback body 10 will be cut.

이렇듯, 전원(29)에서 열선(20)으로 전류가 공급되어 열선(20)이 톤백 본체(10)를 용융, 절단한 후, 도 5에서와 같이, 결속선(13)으로 본체(10)를 인양하게 되면, 당초 본체(10)에 충전되었던 토사 또는 쇄석 등의 충전재(19)는 해저 또는 하상에 존치된 채, 절단된 본체(10)가 충전재(19)로부터 이탈되면서 인양됨으로써, 톤백 본체(10)의 인양시 소요되는 장비의 출력을 획기적으로 절감할 수 있을 뿐 아니라, 신속하고 안전한 톤백 본체(10)의 회수가 가능하게 된다.
As such, after the electric current is supplied from the power supply 29 to the heating wire 20 and the heating wire 20 melts and cuts the toneback main body 10, the main body 10 is connected to the binding line 13 as shown in FIG. 5. When lifting, the filler 19 such as soil or crushed stone, which was initially filled in the main body 10, is lifted while being separated from the filler 19 while the main body 10 is removed from the filler 19 while remaining on the seabed or the bottom. Not only can dramatically reduce the output of the equipment required during the lifting of 10), it is possible to quickly and safely recover the toneback body 10.
