Embodiment Construction

[0023] After winding the circular prestressed high-strength steel wire on the outer surface of the tube core, a layer of interface agent with a thickness of 2.0mm is sprayed on it to carry out the interface between the metal and non-metal materials. After treatment, use a roller jet machine to spray a protective layer of dry hard cement mortar with a compressive strength of 48MPa and a thickness of 25mm.

Abstract

The invention discloses a method and a device for producing a prestressed concrete cylinder pipe by surfactant, and belongs to the technical field of the method and the device for producing the prestressed concrete cylinder pipe. An annular prestressed high-strength steel wire is wound on a cylindrical thin steel plate tube at the outer surface of a pipe core. The method is characterized by also comprising the following steps of: spraying a layer of surfactant of which the thickness is 1.5-2.5mm on the surface after winding the annular prestressed high-strength steel wire on the cylindrical thin steel plate tube at the outer surface of the pipe core; processing the interface bonded between a metallic material and a non-metallic material, and then spraying a dry hard cement mortar protection layer by a roll injection machine. According to the method, the adhesive bonding performance between the surface of a thin steel tube of the pipe core, the surface of the annular prestressed high-strength steel wire and the cement mortar protection layer is enhanced by processing the interface between the metallic material and the non-metallic material; the protection effect of the cement mortar protection layer is enhanced, and the durability and the service life of the prestressed concrete cylinder pipe are improved. The device can finish the method.

Description

technical field [0001] The invention belongs to the technical field of methods and equipment for producing prestressed steel cylinder concrete pipes, and in particular relates to a method and equipment for producing prestressed steel cylinder concrete pipes using an interface agent. Background technique [0002] Prestressed concrete cylinder pipe (Prestressed conerete cylinder pipe, referred to as PCCP), in which the small diameter is made of concrete on the inside, and the circular prestressed steel wire is wound on the outside of the tube core of the outer circular thin steel tube, and the cement mortar protective layer is made. The pipe, the structural type is called the liner type, and the code name is PCCPL. Prestressed steel cylinder concrete pipe has the advantages of high internal and external pressure resistance, good impermeability, crack resistance, excellent corrosion resistance, and low cost. It is the first choice for water diversion, water supply, water conser...
