Abstract
The utility model discloses a project tunnel air duct which comprises a stainless steel layer (1). Wherein, a polyester composite material layer (2) is adhesively connected with the outer wall of the stainless steel layer (1) whose outer wall is adhesively connected with an outer stainless steel layer (3). Wherein, the stainless steel layer (1) and the outer stainless steel layer (3) are spirally wound by stainless steel stripe whose stripe edges are connected through welding. The polyester composite material layer (2) is a solidified resin adhesive layer and a meshed glass fiber yarn is fixed inside the glass adhesive layer. The project tunnel air duct is characterized by simple structure, low cost, high strength, low specific density, convenient installment, strong impact assistance and erosion assistance.
Description
Technical field
The utility model relates to a kind of air pipeline system, relate in particular to the engineering tunnel air duct at a kind of engineering tunnel and down-hole, mine driving bursting work scene.
Background technology
The used engineering tunnel air duct in present various engineerings tunnel or down-hole, mine mainly contains following two kinds:
The one, canvas engineering tunnel air duct, this air duct are individual layer canvas structure, and its advantage is that price is relatively cheap, quick and easy for installation, its shortcoming is that intensity is very low, particularly in the blast area, the engineering tunnel air duct of blast area abolish almost can not be used continuously after the explosion.
The 2nd, steel pipe engineering tunnel air duct, this air duct are common monolayer steel pipe structure, and its advantage is the intensity height, and shortcoming is that price is expensive, than great, inconvenience are installed, in a humid environment easy-to-rust.
The utility model content
The purpose of this utility model provides a kind of intensity height, the engineering tunnel air duct that proportion is little.
For achieving the above object, a kind of engineering tunnel air duct is provided, comprise stainless steel layer, its key is: the outer wall at described stainless steel layer is bonded with the polyester composite layer, stainless steel layer outside the outer wall of described polyester composite layer is bonded with.
This sandwich design had both made engineering tunnel air duct have high-intensity characteristic, had advantage simple in structure, easy for installation again, and simultaneously, inside and outside stainless steel layer has guaranteed that also engineering tunnel air duct has very high corrosion resistance.
Described stainless steel layer twines for the stainless steel band spirality, and for weldering connects, the thickness of described stainless steel band is 0.1～0.5 millimeter between the band edge of spirality stainless steel band, and width is 125～250 millimeters.
Described outer stainless steel layer twines for the stainless steel band spirality, and for weldering connects, the thickness of described stainless steel band is 0.1～0.5 millimeter between the band edge of spirality stainless steel band, and width is 125～250 millimeters.
Spirality is twined design, makes that the manufacturing of engineering tunnel air duct and processing are easier, and engineering tunnel air duct length can be arranged arbitrarily.
The resin glue-line of described polyester composite layer for solidifying is fixed with net structure glass yarn in this glass glue-line, the thickness of described polyester composite layer is 5～10 millimeters.
The resin glue-line holds tightly together stainless steel layer and outer stainless steel layer, the Thickness Design of engineering tunnel each layer of air duct can change according to the difference of environment for use, the polyester composite layer has reduced the proportion of engineering tunnel air duct, reduce cost, also improved the anti-impact force of engineering tunnel air duct.
Remarkable result of the present utility model is: provide a kind of simple in structure, cost is low, the intensity height, and proportion is little, and is easy for installation, and anti-impact force is strong, corrosion resistant engineering tunnel air duct.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an external view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2: a kind of engineering tunnel air duct, comprise stainless steel layer 1, be bonded with polyester composite layer 2 at the outer wall of described stainless steel layer 1, stainless steel layer 3 outside the outer wall of described polyester composite layer 2 is bonded with.
This sandwich design had both made engineering tunnel air duct have high-intensity characteristic, had advantage simple in structure, easy for installation again, and simultaneously, inside and outside stainless steel layer has guaranteed that also engineering tunnel air duct has very high corrosion resistance.
Described stainless steel layer 1 twines for the stainless steel band spirality, and for weldering connects, the thickness of described stainless steel band is 0.1～0.5 millimeter between the band edge of spirality stainless steel band, and width is 125～250 millimeters.
As shown in Figure 2: described outer stainless steel layer 3 twines for the stainless steel band spirality, and for weldering connects, the thickness of described stainless steel band is 0.1～0.5 millimeter between the band edge of spirality stainless steel band, and width is 125～250 millimeters.
Spirality is twined design, makes that the manufacturing of engineering tunnel air duct and processing are easier, and engineering tunnel air duct length can be arranged arbitrarily.
As shown in Figure 1: the resin glue-line of described polyester composite layer 2 for solidifying, in this glass glue-line, be fixed with net structure glass yarn, the thickness of described polyester composite layer 2 is 5～10 millimeters.
Resin glue-line 2 holds tightly together stainless steel layer 1 and outer stainless steel layer 3, the Thickness Design of engineering tunnel each layer of air duct can change according to the difference of environment for use, the polyester composite layer has reduced the proportion of engineering tunnel air duct, reduce cost, also improved the anti-impact force of engineering tunnel air duct.
Its working condition is as follows:
The utility model is installed in the suitable installation site in various engineerings tunnel or down-hole, mine can be used.
