    专利说明:

    The invention is a floating pier equipped with a longitudinal, central, uninterrupted channel, with a depth sufficient to allow seawater to communicate with the channel via openings. The floating pier’s deck has a grating over at least the part of the deck that lies directly above the channel.
    Background
    Floating piers are used for year-round operations. The deck of a floating pier must have a nonskid surface, and it must be taken into account that the pier will be used during the 10 winter season. The pier’s deck must be drained to prevent accumulation of water, snow.
    Floating piers of steel and concrete are known to exist that have a longitudinal, uninterrupted channel(s) placed either centrally or along the floating pier.
    A concrete floating pier is known from US 2014182504 that has a longitudinal, central, uninterrupted service channel. A grating lies atop the floating pier surface. The service channel has not a depth sufficient to allow seawater to communicate with it.
    A concrete floating pier is known from US 7845300 that has a longitudinal, central, uninterrupted service channel. A grating lies atop the floating pier. The channel can be defined as a service channel and therefore does not have a depth sufficient to allow seawater to communicate with the channel.
    NO 874272 shows a floating bridge of the pontoon type, where the ends are fastened to abutments. The bridge has varying waterline area in the longitudinal direction. The pontoon is box-shaped, and its interior chamber is divided up by a series of longitudinal and latitudinal partitions. The outer walls of the upper portion of the pontoon are in certain areas executed with openings in the waterline area and are thus open for water inflow. The floating bridge appears to lack a grating.

    This does not indicate that the channel has a depth sufficient to allow seawater to communicate with the channel via the openings, and that there is a grating over the channel.
    It is a well-known problem that ice and snow accumulate on the pier deck and that these are very difficult to remove. The option to install electric heating cables on floating piers of this type is too costly in relation to the need. Snow removal is ineffective and can present hazards for personnel.
    Objective
    The objective of the present invention is to overcome or mitigate at least one of the disadvantages of current technology and create a floating pier that is designed for safe and simple use during the winter season, so that snow, ice, etc. will fall through the 15 grating and melt.
    Invention
    The invention is defined in patent claim 1. The innovation of this invention is that 20 floating piers are equipped with a longitudinal, central, uninterrupted channel, with a depth sufficient to allow seawater to communicate with the channel via openings. The floating pier’s deck has a grating over at least the part of the deck that lies directly above the channel. Snow will fall through the grating and melt / drain off via the channel and then via the openings. The result will be a snow-free deck surface.
    The invention is elaborated in the enclosed illustrations.
    Figure 1 shows a perspective drawing of a floating pier shaped in accordance with the invention.

    Figure 2 shows a perspective drawing of a floating pier on edge and seen from the underside.
    Figure 3 shows a vertical profile of the floating pier.
    Figure 4 shows a vertical profile of the floating pier lying on the water surface.
    The floating pier, as shown in the invention, comprises component 1, deck 2, service 10 channels 3 on the upper side of the floating pier, longitudinal channel 4, openings 5 on the underside of the floating pier, and a grating 6.
    Service channels 3 are used to stretch tension cables for the coupling system of each element. Service wires/conduits such as water pipes, power cables or signal cables etc. 15 can be laid in channel 4 when necessary. The longitudinally running channel 4 is centrally located in the floating pier and is trapezoid-shaped. The purpose of the sloped sides of the channel itself has to do with making the channel easy to dismantle during production. Channel 4 may have different shapes.
    Openings 5 distributed along the entire underside of the floating pier and are used to distribute water inflow into channel 4. Openings 5 can have different diameters. The best result is obtained with openings having a round-shaped cross-section measuring 25 cm in diameter. This geometric shape enhances water inflow into the channel.
    If an alternative form is executed, at least one anchorage point 7 for fasting the pier to an abutment can be installed on the underside of channel 4. The advantage of this type of execution is that the chain is readily accessible from the walking area, since gratings 6 can be easily dismantled to get to channel 4 with anchorage point 7. This thereby avoids having to cross anchorage chains, which is something that must be done with 30 traditional concrete piers.
    Grating 6 lies atop the longitudinally running channel 4. Coverage of the entire walking area entails some challenges in terms of the buoyancy of the concrete pier itself At the same time, this entails a consequence in terms of price of the finished product. It is 5 sufficient that grating 6 is located only in the walking area in the centre of the pier, i.e.
    atop the longitudinally running channel 4.
    The floating pier as illustrated in the invention is a heavy floating pier made of steelreinforced concrete. It lies in the water year-round and can withstand ice. Because of its 10 weight, a heavy floating pier of this type has good load capacity and very good stability in ocean turbulence.
    When in use, the floating pier lies in the water at about level X, with seawater coming in through openings 5 and filling channel 4. Snow falls onto the deck and through 15 gratings 6 and melts /drains off via channel 4, so that the snow melts without the application of artificial energy.
