Description

Work ship integrated apparatus for forming air wall}

The present invention relates to an integrated air wall forming apparatus for an aquatic work vessel, and more specifically, an air bubble curtain is not formed at a remote distance from a water work vessel that performs underwater blasting or underwater drilling, but directly to the aquatic work vessel. An air wall that is provided as an integral type and effectively blocks contaminants such as floating soil generated during underwater blasting or underwater drilling work in the circumference area of the underwater work ship by using the remaining compressed air and using the remaining compressed air. ) It relates to an integrated air wall forming apparatus on the water work ship that can be formed.

The conventional silt protector is to prevent the spread of pollution by installing cloth-shaped obstacles in the sea.It is used in various marine projects such as breakwater construction, reclamation, and port structure construction. It is also used in construction.

In other words, prevention of the spread of sediment and silt generated in seawater during reclamation work, prevention of seawater pollution by dredging routes, riverbed maintenance, revetment, breakwater, pollution prevention in nearby sea areas during port construction, aquaculture around offshore construction, and clean water areas , It has the purpose of preventing damage to beaches.

The anti-pollution film is the main function of preventing the diffusion of floating soil or wastewater generated during offshore construction. In addition, it plays a very important role in preventing the decrease in primary production due to the inhibition of photosynthesis of phytoplankton, preventing the effect of reducing the food source of zooplankton, and the development stage of fish eggs and fry.

In this regard, Republic of Korea Patent Publication No. 1262364 discloses a pollution prevention device for artificial reefs, Registration Patent No. 1262364 is a plurality of floating bodies floating in a river or sea; A fouling prevention film extending below each of the floating bodies to prevent the fouling water from spreading to the surrounding river or sea water; And a main anchor block provided on a river floor or a sea floor to prevent loss of the pollution prevention film, wherein the main anchor block includes: a body provided on the sea floor of the river or sea; A connecting ring member provided on the main body and the floating body to connect the pollution prevention film; And a main growth groove that is formed to be open on both sides of the body to allow seaweeds on the sea floor to grow, and each of the floating bodies connects wires to one or both sides; Each of the wires is detachably connected to a sub-anchor block for an artificial reef that is fixed to the seabed of a river or sea to maintain a distance between the floating bodies so as to prevent the pollution prevention membranes from approaching each other.

Registered Patent Publication No.1262364 is to reduce the cost of waste disposal due to collection by changing the shape of the anchor block fixed to the seabed of a river or sea to prevent the loss of the pollution prevention film so that it can be used as an artificial reef without collection after construction. And there is an advantage of preventing safety accidents that occur during collection.

However, the conventional anti-pollution device such as Korean Patent Publication No. 1262364 is a structure in which an anti-pollution film is connected to an anchor block provided on the bottom of the sea, and as the underwater position is fixed, when a situation where expansion or reduction of the construction area is required occurs. There is a disadvantage that a lot of manpower, equipment, and time are required to move the location of the anti-pollution device.

In addition, conventional anti-fouling devices such as Korean Patent Publication No. 1262364 have difficulty in traction of the floating body by the ship due to the resistance of water to the anti-fouling film. Therefore, in order to install the anti-fouling film on the sea or cancel the installation state, The anti-fouling membrane must be loaded onto the ship and dropped into the water after moving to the construction area.Therefore, there is a disadvantage that a lot of manpower, equipment, and time are required to move the position of the anti-pollution device when a situation requiring expansion or reduction of the construction area occurs.

In addition, a conventional anti-pollution device such as Korean Patent Publication No. 1262364 forms a specific shape in a state in which a plurality of floating bodies are tightly coupled to each other, so that a connected floating body is formed when a situation requiring expansion or reduction of a construction area occurs. There was a disadvantage that it was difficult to change the shape, and in order for the work ship to move in and out of the construction area through a floating body in the form of a closed loop, there was a hassle of disassembling the connection structure with the anchor block after dismantling the fastening structure between the floating bodies. .

On the other hand, the existing air bubble generator allows the formation of an air bubble curtain at a distance (approximately 100 m or more) separately from the water work vessel performing underwater blasting or underwater drilling due to safety issues, so underwater blasting or underwater drilling The effect of blocking contaminants such as suspended soil generated during work with air bubbles is not so great that damage may be propagated to surrounding farms, clean waters, beaches, etc. due to noise, vibration, and diffusion of pollutants. Since compressed air must be formed by using or a motor must be used, there is a problem that environmental pollution and maintenance and operation costs may be high.
