Description

The invention relates to techniques for protecting the environment from explosive effects, ensuring safety and tight containment in a confined space of a pre-fabricated structure of explosion products containing high-speed metal fragments, aerosols and gaseous substances. The main purpose of the structure is the localization, temporary storage and carrying out work with dangerous objects in it, including emergency ammunition in fragmentation packaging, the transportation of which from the location is impossible; special ammunition and charges containing harmful substances in their composition, subjected to emergency impacts, requiring urgent disassembly in emergency conditions; sabotage and terrorist devices of unknown origin and composition, requiring immediate localization at the place of their discovery.

Known protective structure (s. RF No. 95113901, E 04 H 9/04, publ. 08/10/97), separately standing with a rectangular reinforced concrete building and a mine emergency exit. The casing is made of a disk-shaped protective enclosure with portholes and a hatch located in the upper part, a flexible facing with an intermittent support ring, for example, polyurethane foam, in the lower part and installed in a reinforced concrete bowl with radial branches, and the casing, along the equatorial rib, and the bowl, along the perimeter of the side at the level of the bottom of the branches, is equipped with embedded parts to which articulated support-connecting elements are pivotally mounted in radial branches, while the ice ones are covered with protective nets, and the bowl at the lower point has a drainage funnel.

The main disadvantage of the structure is that it does not provide reliable localization of explosion products of environmentally hazardous objects, the impossibility of its transportation to the location of the explosive object in parts.

Closest to the invention, the technical solution is "Prefabricated device for the localization of explosion products" RF patent No. 2168107 F 17 C 1/00 publ. in BI No. 15 dated May 27, 2001. The device comprises a reinforced concrete shell, a closed sealing metal shell made of cuvette-shaped panels hermetically connected to each other along the perimeter of the open ends, a layer of damping material, an inner metal shell. The reinforced concrete shell is made of collapsible sections, lined with cuvette panels on the outside, and with metal covers on the inside, forming a sealing shell-frame. A layer of damping material is placed between the shell-frame and the inner metal shell. A power cargo sarcophagus is installed on the sealing shell-frame, made of multi-tiered and consisting of collapsible reinforced concrete sections, rigidly interconnected.

The device does not adequately meet the technical and operational characteristics, since for guaranteed localization of explosion products within the volume, the device should be a closed module with a lock system.

The objective of the invention is to improve the technical and operational characteristics, ensuring maximum environmental safety of the environment.

The problem is solved in that in a prefabricated-monolithic localizing structure containing a reinforced concrete shell made of prefabricated sections, lined with cuvette panels on the outside, and with metal covers on the inside, forming a sealing shell-frame, an inner metal shell, a damping layer material, placed between the shell-frame and the inner metal shell, a power cargo sarcophagus, made in many tiers, is installed on the sealing shell-frame m of concrete sections rigidly interconnected, the construction is designed as a sphere-like domes and provided with a pressure seal. Collapsible sections are solid-stage supporting-arch elements connected to each other by end surfaces. The shell frame made with the ceiling and bottom parts, which are reinforced concrete slabs with wedging elements, wrapped with steel sheets, is installed on a collapsible reinforced concrete foundation slab consisting of profile-connected sectors. The reinforced concrete sections of the power cargo sarcophagus are equipped with fittings and are rectangular-shaped blocks of rectangular cross-section, rigidly fastened to the base plate and to each other with metal anchor rods in a checkerboard pattern relative to the joints of the blocks. The reinforcement of the power cargo sarcophagus blocks is made by horizontal welded meshes and vertical reinforcement in the form of load-bearing spatial structures installed at their full height. The base plate is reinforced with flat mesh made of reinforcing steel. The joints of the cuvette-shaped panels are equipped with sealing covers fixed with bolts.

The proposed structure is a unified module that preserves structural integrity and tightness when exposed to shock waves and explosion products, protected from the inside by a damping layer with sealing elements and an external reinforced concrete power cargo sarcophagus. For ease of operation, the structure is equipped with a pressure seal operating from an external load as a protective one and from an emergency explosion inside the device as a protective seal.

The invention is illustrated in figure 1 - where a diagram of a prefabricated-localization localizing structure is shown, in figure 2 - section AA, figure 3 - section BB, figure 4 - view B.

The protective structure is a unified module made in the form of a sphere-shaped dome. The main structural element is a collapsible sealing shell-frame 1, consisting of separate reinforced concrete sections with a bottom and ceiling plates 2 and jamming elements 3, rigidly interconnected with bolts 4 and lined with cuvette panels on the outside, and metal with metal on the inside lids and a sealing cover 5. The shell frame 1 is installed on a collapsible reinforced concrete foundation plate 6, consisting of profile-connected sectors connected by a central mono cast plate 7. The base plate 6 is reinforced with flat grids of reinforcing steel. Outside, the shell-frame 1 is covered with a reinforced concrete power cargo sarcophagus 8, made multi-tiered in the form of collapsible tiers of reinforced concrete ring-shaped blocks of rectangular cross section, inverted with steel sheets. Collapsible tiers are interconnected along the end surfaces and are a continuous-step supporting-arched element.

The blocks are rigidly bonded to the foundation plate 6 and to each other with metal anchor rods 9 in a checkerboard pattern relative to the joints of the blocks. Reinforcement of blocks is carried out by horizontal welded meshes and vertical reinforcement in the form of load-bearing spatial structures installed at their full height. In the manufacture of the shell-frame 1, the foundation plate 6 and the power cargo sarcophagus 8, concrete of class B30 (grade M400) is used.

To protect the sealing shell-frame 1 from the effects of fragments and cumulative jets, a sinus wall and foundation layer is made of expanded clay. A ribbed-annular collapsible metal dome 11 is installed inside the room. Expanded clay 10 is poured into the gap between the dome 11 and the shell frame 1. The floor of the interior is equipped with two circular steel plates (not shown). Between the expanded clay layer 10 and the sealing shell-frame 1, an inner metal shell is placed. The construction is equipped with a pressure seal 12, which has two protective shutters (an armor plate and a pressure seal), operating from external loads as protective ones and from an emergency explosion inside the device as protective and sealing ones. The power cargo sarcophagus 8 can be bunded with a layer of gravel or soil 13, which, on the one hand, plays the role of an additional attached mass and, on the other hand, serves to filter probable aerosols in case of depressurization of the shell-frame 1 during an emergency explosion.

All collapsible elements of the protective structure are designed and manufactured with mass and overall dimensions that allow them to be transported and installed by existing technical means.

Thus, the proposed invention on a prefabricated-monolithic localizing structure provides:

- The shortest possible time for transportation and assembly of the structure at the location of the explosive facility;

- guaranteed localization of explosion products within the structure in the event of an emergency explosion in it;

- the ability to carry out the necessary amount of work to neutralize a localized object inside the structure;

- maximum ecological safety of the environment, people and buildings during the localization of the explosion products, radioactive, chemical and other substances;

- repeated use of the structure.
