Description
Technical Field
The invention relates to the field of building construction environmental protection, in particular to an enclosing wall capable of reducing dust.
Background
Nowadays, people have higher and higher requirements on the environment, the environmental protection awareness is stronger and stronger, and the environmental protection concept requirements almost reach all walks of life; for example, a building construction site which is easy to generate dust flying can be normally carried out when the environmental protection standard is met in the construction and production processes; at present, when a construction site is constructed, a construction area needs to be sealed and blocked by using a wall, and meanwhile, a water spraying nozzle is arranged at the upper edge of the wall and forms a layer of water mist; when the raise dust in the place spreads the enclosure edge, dust and water smoke combine, subside to effectively reduce the exoergic degree of dust, thereby guarantee the outside air of construction place, environment to a certain extent.
However, this method also has more inconveniences: for example, the sprinkling nozzles are mostly arranged at the edge of the enclosing wall, and the inside of the field still flies dust, which poses great threat to the health of inside constructors; in addition, when the wind power is high, the water mist sprayed by the water spraying nozzle is easily blown away by airflow, and the dust can not be blocked; meanwhile, dust in the field can be blown out by strong wind to pollute the air at the lower wind port; meanwhile, even after the water mist is combined with the dust, the water mist is blown to a lower air port by strong wind, a large amount of water mist containing dust droplets is mixed in the air, and the normal passing of surrounding residents is seriously influenced; therefore, the current scheme can only reduce the escape of dust to a certain extent, but still cannot reach the standard and concept of green construction; in addition, when wind-force is great, closed enclosure produces great windage, receives wind-force great, causes easily that the enclosure root is not hard up, the junction drops, long-term the use causes easily that whole enclosure is blown down, is scraped and flies, not only does not play the effect of dust fall, has certain potential safety hazard even.
Disclosure of Invention
Aiming at the problems, the invention provides the building construction dust falling enclosure wall which can effectively reduce the flying condition of dust inside and outside a construction site, effectively improve the construction environment and ensure the health of constructors; and meanwhile, the air quality around the construction site is improved, and the influence of construction on the surrounding environment is further reduced.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the building construction dust fall enclosure wall comprises a base, a baffle and a water supply system; the base is arranged at the edge of the field;
the water supply system comprises a vertical supporting pipe, a transverse supporting pipe and a high-pressure water pipe; the vertical supporting pipes are arranged on the base at equal intervals, adjacent vertical supporting pipes are communicated by the transverse supporting pipes, and the transverse supporting pipes are arranged at equal intervals in the vertical direction; the high-pressure water pipe provides a high-pressure water source for the vertical supporting pipe and the transverse supporting pipe;
the baffle comprises a sleeve and spraying pipes, the sleeve is arranged on the upper side edge of the baffle, the spraying pipes are equidistantly distributed on the baffle, one end of each spraying pipe extends to the cylinder wall of the sleeve, and the other end of each spraying pipe extends to the lower side edge of the baffle;
