Description

[0001] The present invention relates to a float linear anti-scattering bracket and an underwater membrane vertical holding device using the same,

The present invention relates to an anti-fluid linear anti-scattering bracket for preventing the spread of abundant water around a construction water body during coastal or river embedding, dredging and dike, seawall, marine jacket file, sea general file installation, maritime bridge construction, The present invention relates to a membrane vertical holding device.

In the case of various coastal and river constructions such as landfill, dredging, sandstone and various protection ball dropping, embankment and embankment construction, shattering ball or shredder, In addition to not being environmentally friendly, it is common for local residents to set up pollution prevention facilities to prevent them from being transported and spread to neighboring waters.

As a typical anti-dumping facility, there is an anti-dirt film which is suspended by a fine mesh chain anti-tacking membrane at the port providing buoyancy, and a heavy object is held at the bottom of the anti- There has been a lot of research in that there is a problem that mooring or anti-torn film is moored to a fixed structure or a subterranean zone.

In the conventional technique as described above, a plurality of anchors are installed on the lower bottom surface to maintain the anticorrosive film, so that there is a great deal of inconvenience in moving and reinstalling the product. In case of a high flow rate, It is difficult to maintain the vertical durability of the vertical durability and to maintain the linearity of the vertical durability. In the case of the portable dirt prevention film using the steel pipe, breakage (bending of steel pipe) due to algae, It is effective for small scale dredging in the coastal area, but the large-scale operation (pump dredging, construction of offshore wind farm, construction of jACKET PILE among dock facilities, etc.) There are factors,

The reason is that

1. Existing steel pipe type antifouling film has excellent rigidity, but it has a low ductility, and continuous rolling and pitching phenomenon due to sea surface waves and continuous friction with the construction work line cause breakage of the joint portion,

2. Existing mobile anti-corrosion film has excellent ductility, so it does not cause the same phenomenon as in the case of steel pipe type, but it is difficult to maintain linearity as one oil pipe. In order to solve such a problem, since a bracket is used to form a combined body, it is formed into a relatively large-sized system, which causes disadvantages in economy and workability,

3. Conventional antifouling film is difficult to move because it uses a large amount of anchor to maintain the resin of the linear body and the film lowered by the underwater, and there are disadvantages such as the loss of hands caused by bad weather and re- And solving the above-mentioned problems is a problem of the present invention.

In general, the pipe used in the floating structure of the present invention is made of PE (polyethylene), and the superiority of the buoyancy of the pipe and the safety of the joint due to the heat fusion are guaranteed, but it has a defensive property In order to compensate for the severe linearity caused by the ductility of the pipe, it is necessary to combine rigid steel pipes against the algae and the waves to have the binding force to solve the problem of the distortion and warping of the underwater film linear shape provided with the anti-

The present invention relates to an upper oil pipe insertion portion 10 which is installed at an upper portion of the upper oil pipe insertion portion 10 by inserting an upper oil pipe 100 and has a circular annular shape and a bracket upper portion And the upper and lower oil pipe insertion portions 10 and 10 are provided on the upper and lower sides of the bracket upper and lower fixing portions 15 and 15, An upper upper support lower support reinforcing portion 12 having a triangular shape and provided as a reinforcing bar so as to support a portion 10 therein,

A lower oil pipe fixed connection block 13 for fixing a lower oil pipe insertion portion 11 for inserting a lower oil pipe 200 at a predetermined interval in the lower portion of the upper oil pipe lower support reinforcement portion 12, ,

The upper and lower support reinforcement portions 14 are provided on the lower both side surfaces of the lower-portion oil pipe insertion portion 11 and are provided as reinforcing bars so as to support the lower-portion oil pipe insertion portion 11 therein. The present invention is to provide a sub-fluid linear anti-scattering bracket 1 made up of an anti-fluid linear anti-scattering bracket 1 and an underwater film vertical holding apparatus using the same.

The present invention is made by making a buoyant material as a single line, minimizing unnecessary attachments to minimize weight, and forming a free-curving phenomenon in a water surface of a flexible pipe (buoyant material) The material of the lower floating pipe is arranged as steel pipe,

In addition, a buoyancy control valve is installed at the upper part of the lower oil pipe to position the device in a part of the water, so that continuous rolling and pitch phenomena caused by the sea surface wave and damage caused by continuous friction with the construction work line can be reduced And prevented by the anti-collision and anti-movement stoppers and anti-rotation devices,

It is possible to prevent contamination of sewage when the wave is severe by installing pollution preventing partition,

Since the lower suspended pipe is made of steel pipe and the center of gravity is below the water surface, stability against the conduction is ensured and the submerged membrane is secured to the vertical direction, so that it is not necessary to have a plurality of anchors such as general anti- (Polyethylene), which is strong against external force and excellent in restoring force, is easy to maintain and easy to construct, and is easy to construct.
