(1) ant wind load :≤20m/s; Anti-snow load :≤10Kg/m
2; Hoisted load: nothing.
(2) skeleton: arch tube, cable-stayed support adopt the galvanizing pipe of φ 32X1.5, the vertical trombone slide in three roads all adopts the galvanizing pipe of φ 25X1.2.Adopt the zinc-plated draw-in groove of greenhouse special hot, 0.7 millimeter of draw-in groove thickness, is arranged in booth two sides, every side 2 roads, plastic card silk fixed film; One pull bar in 5 meters, interval; It is underground that connector all adopts zinc-plated processing big-canopy framework directly to insert, and need not make basis.Every 4 grades one of pile.
(3) what cladding material was used is the long-lived film of individual layer, additional sunshade net.
(4) through the test of raising pigs in 1 year, result was as follows:
The variation of table 2 plastic tent piggery house temperature and traditional pig house and outdoor each monthly mean temperature
Note: capitalization is that difference is extremely remarkable, P<0.01; Lowercase is significant difference, P<0.05
Plastic tent piggery house is given up warm seasonal variety and is approached with the outer temperature of house, differs increasing with traditional pig house room temperature, especially summer and winter, is unfavorable for raising pigs.
The variation of table 3 plastic tent piggery house various quarters day and night temperature
Note: capitalization is that difference is extremely remarkable, P<0.01; Lowercase is significant difference, P<0.05
It is larger that plastic tent piggery house is given up warm day and night temperature, approaches with the outer temperature of house, higher than traditional pig house, is unfavorable for raising pigs.
The variation of table 4 plastic tent piggery house humidity and traditional pig house and outdoor each monthly average humidity
Note: capitalization is that difference is extremely remarkable, P<0.01; Lowercase is significant difference, P<0.05
Humidity and outdoor approaching in plastic tent piggery house house, higher than traditional pig house.
The variation of table 5 plastic tent piggery house ammonia concentration
Note: capitalization represents that difference is extremely remarkable, P<0.01
In plastic tent piggery house house, ammonia concentration is less than traditional pig house, is conducive to raise pigs.
Air speed value in table 6 large booth in summer
Note: capitalization is that difference is extremely remarkable, P<0.01; Lowercase is significant difference, P<0.05
In plastic tent piggery house house, wind speed, higher than traditional pig house, is conducive to raise pigs.
