Description

Offshore floating parking lot using concrete pontoons with adjustable buoyancy}

The present invention relates to a floating parking facility that is installed and operated by floating on the sea, and one or more concrete unit pontoons capable of controlling buoyancy are connected and installed horizontally and vertically to form a floating parking lot, so that a general passenger car can be parked as well as floating It relates to an offshore floating parking lot using a concrete pontoon that can control buoyancy, which has the effect of providing durability and buoyancy so that ships can be docked on the outer wall of the parking lot.

FLOATING PIER is a ship's berthing facility that floats a pontoon (a box-shaped float made to float on water) with buoyancy against water, and builds a bottom plate with reinforced concrete, steel plate, wood, etc. on it. It is a structure made to make it easier for passengers to board and load cargo. Since the bottom plate moves up and down along with the pontoon according to the water level, it is mainly used in places where there is a large difference between the tides or other places where there is a lot of water level change.

In general, a pontoon uses an object with a lower specific gravity than water to make a house, various barges, water bike roads, floating piers, water stages, floating solar power plants, boats and yachts, etc. It is used as a floating buoyant for the construction of various offshore structures and structures, including buoys, bridges), fishing port facilities, offshore cage farms, offshore trails and floating bridges or offshore fishing grounds. In recent years, as the demand and distribution of water sports is expanding worldwide, interest in and development of pontoons is increasing due to the demand and necessity for various uses and types of offshore structures.

The pontoon structure is a structure used by life and expensive ships, and is always exposed to freshwater environments such as salt water or ice pressure, typhoons, floods, and waves, so structural stability and durability are very important. In addition, in terms of functionality, it should be possible to combine various sizes and shapes of main pontoon/finger pontoon, etc., and it should be possible to safely protect the use facility lines such as power lines, oil pipelines, and water pipes, and to enable easy maintenance. In addition, it should be possible to install attachments such as facilities for anchoring and boarding ships.

Pontoons are usually made of FRP (FIBER REINFORCED PLASTICS). However, when disposing of a pontoon made of the above material due to aging or disposing of a pontoon damaged due to collision with a docked ship, etc., due to the glass fiber contained in FRP, there are many difficulties in processing and managing the discarded pontoon. .

In addition, as the buoyancy material of the pontoon, a structure in which a styrofoam buoyancy material having a low porosity is wrapped with a resin such as polyethylene is applied so that weight increase can be minimized even when water permeates. The aluminum deck type pontoon is composed of an aluminum frame and a deck made of solid wood on top of a buoyancy material.

The pontoons as described above can be manufactured in various sizes and shapes and have the advantage of being widely used because they can be conveniently manufactured for various attachments and detachments using an aluminum frame with an extruded cross-section.

In order to prevent this, the concrete deck type pontoon is a type in which a concrete floor plate is synthesized on a buoyancy material, and a concrete deck heavier than an aluminum deck is applied, and vibration by waves or users is good. However, it is very important to secure structural performance due to the material properties that should not allow cracking (tensile stress) in the part submerged in seawater.

In addition, by forming a hollow housing using concrete to produce a pontoon, it was often used to maintain its robustness against external impact. There is a disadvantage in that the buoyancy is lowered by

In particular, there is an aspect that it is not easy to maintain a stable balance because the difference in buoyancy force appears according to the difference in the thickness of the concrete injected on each side. In general, general concrete, fiber-reinforced concrete, mesh-reinforced concrete, etc. are mainly used as materials for manufacturing concrete pontoons. Hollow concrete pontoons consist of a concrete shell and a styrofoam core. As it has the largest weight among the three types, it also has the highest stability, making it suitable for berthing facilities of large yachts or vulnerable environments such as typhoons.

On the other hand, as shown in FIG. 1, in a passenger ship terminal or fishing boat docking facility on the shore, as shown in FIG. 1, in general, concrete of a structure protruding for a certain length toward the ocean is buried on the shoreline in contact with the ocean (S) so that a site can be prepared. The berthing facility 20 is installed. At this time, in the passenger ship terminal or the pier where the fishing boat is anchored, it is common that the parking lot 30 is installed on the shore so that it can be used by passengers or fishermen.

However, such piers require time, cost and effort to construct a concrete site projecting toward the ocean. The present invention provides an improved invention using a concrete pontoon capable of controlling buoyancy, which has been patented by the present applicant and has been patented on October 19, 2020. As it is installed in the sea as floating, not only the utilization of the space at the bottom of the bottom is high, but also the cost and process of installing the parking lot are reduced, and the wave resistance is also minimized. do.
