Description
Technical Field
The utility model relates to a belong to city utility tunnel safety prevention and control technical field, concretely relates to novel underground pipe gallery decompression anti-explosion plate.
Background
In the process of production, processing, transportation, storage and use of combustible gas, the phenomenon of gas leakage can occur due to artificial unsafe behaviors, unsafe states of objects and the influence of the surrounding environment, the leaked gas forms mixed gas with air under the action of air convection, when a certain explosion limit is reached, large-area combustion and explosion can occur when meeting a fire source meeting the minimum ignition energy of the gas or substances with certain heat, and if a local closed space or partial restriction can form a turbulent flow acceleration condition, the combustion can be converted into detonation to cause more serious harm.
The destructive action of underground pipe gallery gas pipeline explosion mainly is that the shock wave produces, and explosion shock wave carries a large amount of explosive fragments, will cause the damage to underground structure and surrounding building under the effect of impact kinetic energy. In the face of the ultra-strong shock wave generated by explosion, the common protection plate is damaged instantly, and the concrete protection plate has large self weight and is not easy to install, so that a novel underground pipe gallery pressure reduction anti-explosion plate is developed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the utility model provides a novel anti board that explodes of underground pipe gallery decompression, this anti board that explodes light in texture, easy installation, ability furthest absorbed the explosion energy to the antiknock effect of underground structure has been increased substantially, thereby the security of assurance structure.
The utility model adopts the technical proposal that: a novel underground pipe gallery decompression anti-explosion plate comprises a ceramic plate, a front side plate, a rear side plate, a U-shaped groove steel plate, a plurality of special-shaped steel plates and a light foam concrete layer; the special-shaped steel plates are uniformly and fixedly arranged inside the U-shaped channel steel plate, a plurality of closed cavities are formed by the special-shaped steel plates and the U-shaped channel steel plate, the front side plate is fixedly arranged on the front side of the U-shaped channel steel plate, the rear side plate is fixedly arranged on the rear side of the U-shaped channel steel plate, the ceramic plate is fixed at the top of the special-shaped steel plates and is mutually fixed with the special-shaped steel plates, the U-shaped channel steel plate, the front side plate and the rear side plate, and a; and the light foam concrete layer is uniformly poured and fixed in a cavity formed by the special-shaped steel plate and the U-shaped groove steel plate.
The special-shaped steel plate is formed by welding a section of arc-shaped steel plate and two flange steel plates.
The special-shaped steel plate flange and the bottom of the U-shaped steel plate are fixed on the wall surface through the steel cushion block and the bolt.
The light foam concrete layer is uniformly connected and fixed through a plurality of studs on the U-shaped channel steel plate.
The utility model discloses have following advantage and positive effect:
1. the utility model discloses structural design is simple, the texture is light, easy installation, the impact effect of resisting explosion fragment shock wave is good.
2. The utility model discloses can install fast at underground pipe gallery structure, through three-layer safeguard measure, reduce shock wave and explosion piece's impact kinetic energy, effectively protected underground structure's safety and personal safety around.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic cross-sectional view of the present invention.
In the figure: 1 is a ceramic plate; 2 is a U-shaped channel steel plate; 3 is a front side plate; 4 is a rear side plate; 5 is a special-shaped steel plate; 6 is a long bolt; 7 is a light foam concrete layer; 8 is a stud; and 9 is a steel backing plate.
Detailed Description
As shown in fig. 1 and 2, the novel underground pipe gallery decompression and explosion-proof plate comprises a ceramic plate 1, a front side plate 3, a rear side plate 4, a U-shaped steel channel plate 2, a deformed steel plate 5 and a light foam concrete layer 7. The special-shaped steel plate is formed by welding a section of arc-shaped steel plate and two flange steel plates.
Firstly, the U-shaped groove steel plate 2 is welded with the stud 8 at a corresponding position, the rear side plate 4 is welded at the rear side of the U-shaped groove steel plate 2, the special-shaped steel plates 5 are uniformly distributed inside the U-shaped groove steel plate 2, the flanges of the special-shaped steel plates 5 and the bottom of the U-shaped groove steel plate 2 are fixed on the wall surface through the steel cushion blocks 9 and the long bolts 6, and the light foam concrete layer 7 is uniformly poured at the front side opening of the cavity formed by the special-shaped steel plates 5 and the U-shaped groove steel plate. When the shock wave and the explosion fragment impact, the deformation of the steel plate and the porous energy absorption of the light foam concrete absorb a large amount of impact energy together.
Then weld preceding curb plate 3 in U groove steel sheet 2 front side, glue at last with ceramic plate 1 through the structure and 5 tops of dysmorphism steel sheet, U groove steel sheet 2 tops, preceding curb plate 3 and posterior lateral plate 4 reciprocal anchorages to form many places confined space (decompression chamber), this is the first layer protection of anti-explosion plate, through destruction and the cavity of ceramic plate, can effectively reduce and strike kinetic energy.
The front side plate and the rear side plate are thin steel plates, and the thickness of the steel plates is obtained through an impact resistance experiment, so that the dead weight of the anti-explosion plate is effectively reduced.
The utility model discloses a theory of operation is: when the piece that the explosion produced strikes to the guard plate fast with the shock wave, at first can break first layer protection ceramic plate, the broken power consumption of ceramic plate, then release by ceramic plate and deformed steel plate, U groove steel sheet, carry out decompression by a wide margin in the airtight cavity (the decompression chamber) that preceding curb plate and posterior lateral plate formed jointly, and then shock wave and explosion piece impact second floor protection deformed steel plate and inside light foam concrete layer, through deformed steel plate and the porous deformation absorption a large amount of impact energy of light foam concrete layer, and effectively prevented the impact kinetic energy of explosion piece, when explosion piece contacts U groove steel sheet bottom, the energy of shock wave has been formed the third layer protection by a large amount of losses, just so can protect the security of structure, reduce the loss that the explosion brought.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
