spiral type acoustic tube

Descripción del producto

spiral type acoustic tube:

Spiral acoustic steel tubes have been widely applied in multiple express highway,high speed railway bridge,municipal bridge engineering and dock,etc,and have gotten good feedback and high praise of vast number of users.

The main specifications of Spiral acoustic steel tubes:

*0 series: *0*1.5、*0*1.8、*0*2.0、*0*2.2、*0*2.5、*0*2.*5、*0*3.0、*0*3.5

*4 series: *4*1.5、*4*1.8、*4*2.0、*4*2.2、*4*2.5、*4*2.*5、*4*3.0、*4*3.5

*7 series: *7*1.5、*7*1.8、*7*2.0、*7*2.2、*7*2.5、*7*2.*5、*7*3.0、*7*3.5

Feature of spiral acoustic steel tube:

Simple operation, excellent leak tightness, strong tensile resistance, strong anti-torsional forces, anti-vibration, no leakage, no deformation, no blocking.

Advantages of spiral acoustic steel tubes:

1.Convenience: simple connection,not need to weld at the site, to adopt the spiral connection,spiral drives double buckle,to lock the sealing rubber rings tightly,from axis to end’s sealing,to prevent loosening effectively,to prevent leakage, convenient and swift,safe and reliable,and reducing the costs.The installation of each joint only needs less than 1 minute,working times are saved greatly and any technical support is not needed. Not to need the preparations that outside the construction site,not to need any facilities,simple and efficient(five times faster than traditional methods), easily to fixed in reinforcing cage,not affected by bad weather.

2.Economy:In the construction of deep bridge bored perfusion, acoustic transmission method test the quality of pile foundation is required for the bored perfusion inspection specification; Acoustic tube should be buried according to design requirements,three pcs should be buried for the ordinary pile foundations with **0cm***0cm pile diameter. In the conventional design,the tubes with outside diameter of ****0mm are adopted generally,wall thickness is 3.0mm left or right,to use adding the casing tube exteriorly to weld at the site in construction, this method requires higher costs. The construction cost of acoustic tubes produced by our company is only about *0% of the construstion cost of ordinary welded tubes,reducing the construction cost greatly.

3.Safety:Bridge pile foundation has strict requirements for the sealing,resistance to leakage,resistance to pressure,etc of the acoustic tubes in the process of pouring concrete,slight mistake could result in blocking pipe and deformation,each construction team is responsible for the welding work of acoustic tube in the construction for ordinary welded tube,can’t test tube wall,connector and sealing and resistance to leakage of the seals at the bottom of tubes,it’s difficult to ensure the quality. Whereas all the acoustic steel tubes produced by our company need to pass three inspection procedures(namely the initial inspection,gas inspection,water inspection),pass rate of our factory products is **0%,so we can ensure that the products meet the technical requirements for the construction.

Installation and use methods

Acoustic tube installation at the bottom section of reinforcing cage: Put Tube A(bottom tube with plug) on the ground to check whether the seal rings are in good condition,then insert Tube B into Tube A until reach the bottom of Tube A, then tighten the screw.Put the acoustic tube into reinforcing cage after connecting,fasten the tubes tightly on the main bar of the reinforcement cage according to specific dimensions. acoustic tube can be fastened by bracket of reinforcing steel bar or reinforcing three main bars for the parts that haven’t reinforcement cage, the binding distance can’t exceed 2meters.
