Description

Dustproof plant fiber screen and combined structure thereof

Technical Field

The invention belongs to the environment protection technology, and particularly relates to a dustproof and dust-absorption combined economical dustproof device.

Background

In recent years, project construction such as urban subway stations, subway lines, real estate construction, drainage pipelines, greening and the like has earthwork excavation and needs dustproof enclosure. Dust from demolition of the house also requires a dust enclosure. At present, most of the maintenance is isolated by adopting plates, and a green plastic screen is additionally arranged for beautifying, or a poster is adhered to the plate surface and the like. The shielding dustproof effect is poor, dust cannot be sucked, and only shielding can be simply carried out. Secondly, also adopt green net to enclose, often dustproof dust suppression effect is relatively poor, usually through the incessant watering, but the effect is not ideal always, does not reach the environmental protection requirement.

The dust pollution in construction engineering construction refers to the pollution to the atmosphere caused by dust particles generated in the production activities of building construction, road and pipeline construction, house demolition, material transportation, material stacking, road cleaning, mud land exposure and the like. The materials which are easy to generate dust pollution on the construction site mainly comprise: sand, lime soil, plaster, construction waste, engineering residue soil and the like. The fine particles such as cement, fly ash, lime soil, sand and stone which are easy to generate dust emission need to be dustproof, such as concrete and mortar mixing operation. The periphery of the fields is sealed and enclosed to control and reduce the pollution of the raised dust to the atmospheric environment. Especially, when the construction is carried out around sensitive targets such as schools, hospitals and houses, the barrier type dust prevention and dust elimination is needed. The dust-proof and pollution-proof requirements are met, and the influence of construction site construction raise dust on the surrounding air environment and the human living environment is effectively reduced.

At present, the plate or the net enclosure has high cost, complex construction and poor effect on tiny dust, and most importantly, the secondary pollution is serious; and the board is easy to be damaged and the dust screen is difficult to be recycled. The common problems in the dustproof enclosure technology are that the dustproof effect is not ideal, the construction is complex and the cost of dustproof facilities is high.

The tapestry 4 is woven by plant fiber and is arranged in the door-shaped supporting frame 3, and is a screen which can prevent dust and can be used as a landscape plant wall; not only can prevent dust, but also can vertically green. The color and pattern of the plants on the tapestry 4 can be selected according to the environmental requirements.

The size of the tapestry 4 is coordinated with the size of the support frame, and the tapestry width B is equal to the frame width L-2 times the diameter D of the frame column; the tapestry height a is the frame height H-the insertion column length H-the diameter D1 of the frame beam.

The tapestry can be produced and processed by using straws of rice, wheat, corn and the like or palm, coconut, hemp fiber and the like as substrates and using a plurality of materials such as nutritional agents, high-quality grass-filling seeds, shaped bamboo chips and the like through special mechanical weaving. The tapestry can be formed by adopting the edge sealing of the periphery of the bamboo chips, reinforcing the middle of the bamboo chips to form a bamboo chip net, increasing the rigidity of the tapestry and adding plant fibers into the bamboo chip net. The tapestry has good water absorption performance, and the plant fiber material can absorb certain water during rainfall; at ordinary times, the water pump is started and the micro-jet water flow is added, so that the dust screen is always kept wet, dust can be effectively inhibited from flying, and the growth of flowers and plants on the tapestry can be ensured.

In addition, the tapestry adopts grass seeds, namely local grass seeds and native plants are selected as much as possible; selecting grass seeds which are easy to survive, have short stems and strong root development and growth power by combining the conditions of local climate, rainfall, tapestry and the like; and thirdly, other grass seeds can be added according to the requirements of places with special greening effects.

(5) Micro-spraying water pipe

The micro-spray pipe 7 is arranged below the frame beam and is aligned to the top of the dustproof plant fiber screen. The micro-spraying pipes can also be arranged in sections under the beams, and reserved pipe joints 15 extend out of the frame column sides L. As shown in fig. 8, the micro-watering pipes 7 of two adjacent panels are connected by a U-shaped connecting pipe 13 with joint hinges 14 at both ends, so that the micro-watering pipes of all the fiber panels form a system. At the end shield, set up vertical pipeline and will spout water pipe and water pump intercommunication a little, form a water supply system, the water pump operation can spray water. The micro-spraying can be fully automatically controlled without manual operation.

When the pipeline water supply condition is not available, the dustproof plant fiber screen can be sprayed by a watering cart. In this case, the tapestry may not be provided with the micro-spray pipe or the water supply equipment.

(6) Auxiliary equipment

The auxiliary equipment comprises a water supply pump, a gate valve, a check valve, a computer control system and the like, and is conventional equipment.

Fig. 9 shows a single screen assembly of a support frame 3, two basic prefabricated blocks 2, and a tapestry 4 combined to form a dustproof plant fiber screen.

The dustproof plant fiber screen can be assembled to form a dustproof enclosure to form a combined structure. As shown in fig. 10 and 11, when the enclosure is dustproof, the single dustproof plant fiber screen 1 is spliced and can be arranged in a straight line shape or in a zigzag shape. According to the shape of the dustproof object, the dustproof object can be combined at will to form a barrier to enclose or shield. Firstly arranging a basic prefabricated block 2, then installing a supporting frame 3, installing a pipe clamp 16, and then hanging a tapestry 4; and adjusting the distance and the position of each screen to complete the overall arrangement.

Dustproof plant fiber screen 1 can be pieced together wantonly because frame post 31 is circular pipe, and two screen straight lines are pieced together, or two screen broken lines are pieced together, and adjacent department is two circular posts and is pieced together, and circular are pieced together non-directional requirement, can satisfy a font or broken line shape and arrange, and the pipe strap 16 of also being convenient for uses.

At the construction site, the dust-proof protective screen is arranged along the periphery of an object needing dust prevention to form a protective screen. In order to keep the humidity of the dustproof plant fiber screen, when the humidity is flat, the water pump and the micro-spray water flow are started, the humidity of the dustproof screen is kept all the time, dust can be effectively restrained from flying and effectively sucked, and the growth of flowers and plants on the screen can be guaranteed.

The moist dustproof plant fiber screen prevents dust from flying, plants can easily grow on the dustproof plant fiber screen, and a landscape is also created. There are three general effects: the dustproof plant fiber screen can prevent dust and absorb dust, the screen can form a vertically-greening landscape, and the screen has a humidifying effect on the surrounding environment.

The dustproof plant fiber screen standardized component is convenient to combine, and two combination modes are provided conventionally. The separation and combination of the tapestry 4 and the support frame 3 form two different assembling modes. The selection mode can be determined according to actual application and warehouse storage requirements.
