Description

The invention relates to floating structures designed to transport objects by waterways, and can be used in the construction of industrial facilities.

A pontoon is known (RF patent No. 2659339, V63S 7/04; publ. 06/29/2018), containing a body, flooding and drainage systems, a kingston with a lid, sling niches with roundings for a smooth bend of pontoon slings, fittings for flooding and drainage systems, closing drives kingstones, devices for protecting the zygomatic keels, made in the form of semiaxes installed inside each sling niche.

The disadvantage of this invention is the lack of function of heating the lower part of the pontoon to prevent freezing into the ground.

A three-dimensional block of an industrial structure is known (USSR Author's certificate No. 887747, IPC E04B1 / 348; publ. 07.12.1981), including a frame, the upper part of which is equipped with a power belt with fence elements attached to it, and the lower one, having a base, is enclosed in a waterproof casing , while the base is made in the form of a horizontal frame, along the perimeter of which wall panels are located.

The disadvantage of this invention is the need to carry out additional installation work at the site of operation of the structure, which consists in the partial removal of the lining of the lower frame belt, the lack of heating of the lower part of the pontoon to prevent it from freezing into the ground.

The objective of the invention is to reduce labor and time costs for the construction and preparation for operation of industrial facilities due to the use of pontoons as a means of transport and at the same time as a platform for placing technological equipment.

The technical result of the invention consists in the most compact placement of the necessary technological equipment on a single site due to the multi-level design and the reduction of requirements for the dimensions of the equipment for transportation, as well as the provision of increased permeability on frozen ground.

The task is solved, and the technical result is achieved by a mobile complex of process equipment on a pontoon base, including a multi-level spatial metal structure installed on the base of the pontoon, on which process equipment and engineering networks are located, and at the base of the pontoon there are two pipeline systems - coolant pipelines and steam pipelines, as well as electric and water heaters, enclosed in sealed compartments, equipped with watertight doors, and the bottom of the pontoon base is reinforced with metal profiles, and in the end part of the pontoon base there are lugs for cables of pulling devices.

According to the invention, at the base of the pontoon, cavities can be mounted with sheets of the inner lining of the pontoon, intended for pouring with inertial damper concrete, above which dynamic units of technological equipment are installed.

According to the invention along the perimeter on the sides of the pontoon there can be located attachment points for a removable skirt of an air cushion, and inside the base of the pontoon there are shafts for supplying air to it from blowers.

The essence of the invention is illustrated by drawings, where figure 1 shows a General view of the mobile complex of technological equipment on a pontoon base, figure 2 - a fragment of the internal structure of the base of the pontoon, figure 3 - the cavity of the sheets of the inner lining of the base of the pontoon under the dynamic unit, figure .4 - air cushion of the pontoon base.

The mobile complex of technological equipment (figure 1) includes a multi-level spatial structure 2 installed on the base of the pontoon 1, on which the technological equipment 3, engineering networks 4 are located, a steam generator 6 is installed on the deck 5 of the base of the pontoon, lugs 7 are installed on the end of the base of the pontoon for attaching cables pulling devices moving the pontoon. Technological equipment may include fittings for switching liquid or gas, separation and heat exchange equipment, pumping and compressor equipment. Engineering networks - pipelines of the main process, drainage and auxiliary pipelines, corridors of cables of power and control circuits. Technological equipment and engineering networks are mounted on a pontoon even before it is sent to the place of operation. The pontoon acts as a transport vessel, at the same time it is the final platform for the placement of an industrial facility and its operation. The use of a pontoon makes it possible to ship objects in maximum factory readiness: technological pipelines and equipment have been installed, service platforms and cable-supporting structures have been installed, areas for inspection and repair of equipment have been provided, passages between installations have been provided, and so on. This can significantly reduce the amount of installation work at the construction site. The use of a pontoon to accommodate technological equipment instead of conventional small-sized boxes eliminates the need to lay a road between blocks, prepare foundations for each block separately, and also significantly reduces the amount of other preparatory work on the site, including backfilling, pile field formation, soil stabilization .

The internal structure of the pontoon base (figure 2) contains two piping systems - coolant pipelines 8 and steam pipelines 9, which are designed to supply coolant from the coolant and steam preparation unit, made, for example, in the form of a steam generator 6 (figure 1). It can be placed both on the pontoon itself as a component of the general installation, and as a separate unit on the construction site. Heating the lower part of the pontoon prevents the pontoon from freezing into the ground, and also reduces friction during the dragging of the pontoon in winter. Pipelines of the coolant and steam are located in sealed compartments 10, access to which is provided through waterproof doors 11 (figure 2). The doors are closed during the transportation of the object by water, and if the pontoon body is damaged, the water remains in the hermetically sealed compartment, not spreading to the other compartments. Thus, flooding is limited and the buoyancy of the pontoon is maintained.

The design of the pontoon provides for the possibility of heating the flooring of the base of the pontoon using electric or water heaters 12 (Fig. 2) located inside the serviced sealed compartments 10 of the pontoon. Electric or water heaters are attached with brackets to the flooring 5, thus providing heating of the upper part of the sealed compartments. This solution helps to avoid freezing of the pontoon base deck and the formation of an ice crust in winter.

The bottom sheets (bottom) of the pontoon base are reinforced with metal profiles of high strength class 13, which ensures the strength and rigidity of the complex structure when it is rolled out onto an unequipped shore and dragged overland.

Dynamic units of technological equipment - rotating units and drives 14 (figure 3) is installed by means of support frames on the flooring 5 of the base of the pontoon above the cavities 15 formed by the sheets of the inner lining of the pontoon. At the time of transportation, these cavities remain empty in order to reduce the overall weight of the structure. When installed on a construction site, these cavities are filled with inertial damper concrete. The presence of concrete significantly reduces the natural vibration frequency of the complex structures and eliminates resonance phenomena. Concrete is poured into the cavity through hatches 16.

Along the perimeter of the base of the pontoon on the sides there are attachment points for the skirt of the air cushion 17 (Fig. 4), and inside the pontoon there are shafts 18 for supplying air from blowers under the skirt, thereby organizing an air cushion. Blowers are blowers with diesel or electric drive, which are mounted on the deck of the pontoon base. This constructive solution preserves the natural cover of the land and does not damage the flora.

The multi-level spatial structure, as well as the elements of the technological equipment complex, are made of fire-resistant materials with the use of fire-retardant coatings.

The metal multi-level structure is designed to take on the weight and transport loads from the equipment and pipelines placed on it, it is a strength element of the rigidity of the pontoon base. The increased rigidity of the pontoon is necessary when carrying out operations of moving the complex to an unequipped shore, dragging it along a relief with a large curvature, tilting at a construction site.

Thus, the claimed invention allows to reduce labor and time costs for the manufacture and preparation for operation of industrial facilities, to place the necessary technological equipment as compactly as possible on a single site, while ensuring the rigidity and reliability of a multi-level structure, and also provides increased permeability on frozen ground.
