Abstract

The utility model relates to the technical field of workshop explosion safety protection, in particular to a safety protection barrier for a fireworks and crackers workshop built on plain. The utility model discloses a protection barrier for a fireworks and crackers A grade workshop built on plain, which comprises a workshop and a protection barrier which adopts a protective claybank according to different earthiness; the protective claybank is dug hollow for building workshop foundation; a main passage and an explosion venting bank face are arranged in the front of the workshop; and the rear face and the side faces of the workshop are provided with explosion preventing faces. The utility model has simple construction, low construction cost and good performance of safety protection, can save occupied land, reduces the labor intensity of a worker, improves the working efficiency of the worker, and has popularization value.

Description

Fireworks and firecrackers A level worker-house, plains region protective barrier

Technical field

The utility model relates to factory building explosion safety guard technology field, particularly builds the security protection barrier in fireworks and firecrackers A level worker-house in the plains region.

Background technology

According to GB50161-92 " Code for safety design of fireworks and firecrackers plants ", the A level building of fireworks and firecrackers factory should be provided with protective barrier.At present, mountain area A level factory building can utilize massif to serve as natural cover, and promptly excavation factory building base cave just can solve the safety curtain problem on massif, and building is at the fireworks and firecrackers factory building in Plain, adopt adjacent factory building must reach the means that certain distance is a safety guarantee at present, such method for protecting exists not enough, causes apart from each other between the factory building, and plant area's floor space is big, increased working strength of workers, not only inefficiency, and easy the initiation is operated against regulations, even causes the accident.

Summary of the invention

In order to overcome above-mentioned drawback, technical problem to be solved in the utility model is, a kind of security protection barrier at Plain building fireworks and firecrackers factory building is provided, and can reduce area of mill site, reduces construction investment, alleviates labor strength.

The technical scheme that is adopted of the utility model technical solution problem is: fireworks and firecrackers A level worker-house, plains region protective barrier, comprise factory building, protective barrier, it is characterized in that: protective barrier adopts the protection earth embankment according to different soil properties, in the protection earth embankment, dig to lack the factory building ground is set, there are main channel, venting of dust explosion dike face in the factory building front, and there is the quick-fried dike face of retaining factory building back, side.

The height of described protection earth embankment is not less than the height of factory building eaves, and top width is not less than 1 meter, and bottom width is not less than high 1.5 times of dike, and dike length exceeds exterior wall before the factory building.

The described protection earth embankment gradient determines that according to different soil properties and needs keeping off the quick-fried dike face gradient can be the 70-80 degree, and the gradient of venting of dust explosion dike face can be the 30-40 degree.

The beneficial effects of the utility model are: construction is simple, and construction cost is low, and the security protection performance is good; Can save the area, alleviate working strength of workers, improve workman's efficiency, have promotional value.

The specific embodiment

At first determine factory building towards, fireworks and firecrackers factory will keep away with a western exposure, north wind as far as possible, its objective is that to prevent summer plant area's temperature too high, increases potential safety hazard; Avoid north wind then can be so that be unlikely to undue cold winter as far as possible, and therefore, building should be tried one's best southwards, and the main channel is east-west.

Dig the trench of a wide 8-10 rice, dark 1.2-1.5 rice, as main channel 2; Earth in the trench is piled the bulwark 4 that is higher than 4 meters toward both sides, and keeping off quick-fried dike face 1 gradient is the 70-80 degree, and the gradient of venting of dust explosion dike face 3 is the 30-40 degree, to prevent the reaction of shock wave.Dig scarcely at quick-fried dike one bank of retaining as required then, determine factory building 5 tofts, toft is arranged in the protection earth embankment 4.Distance between the operation factory building 5 on the same protection earth embankment 4 (calculating from exterior wall) is not less than 7 meters, and the distance between transfer storage facility and the factory building 5 is not less than 10 meters; The factory building 5 in same protection earth embankment 4 not, distance each other is not less than 20 meters.Build up back protection earth embankment 4 top widths and be not less than 1 meter, the dike height is not less than the height of factory building eaves.If toft and protection earth embankment 4 loosen the soil, should build bank protection and collapse to prevent earth.Toft ground should be equal with the road surface, main channel.

Claims

1, plains region fireworks and firecrackers A level worker-house protective barrier, comprise factory building, protective barrier, it is characterized in that: trench digging is built furrow on the level land, the excavation breach is provided with the factory building position in furrow, the main channel is left in the factory building front, and the worker-house periphery is built gutter, opposite, worker-house, it is domatic to be that the back of front-seat earth embankment is provided with venting of dust explosion, forms the protection earth embankment of factory building back, side.

2, according to fireworks and firecrackers A level worker-house, the described plains region of claim 1 protective barrier, it is characterized in that: the height of described protection earth embankment is not less than the height of factory building eaves, and top width is not less than 1 meter, and bottom width is not less than high 1.5 times of dike, and dike length exceeds exterior wall before the factory building.

3, according to fireworks and firecrackers A level worker-house, the described plains region of claim 1 protective barrier, it is characterized in that: it is the 50-60 degree that the described protection earth embankment gradient is kept off the quick-fried dike face gradient, and the gradient of venting of dust explosion dike face is the 30-40 degree.
