Problems solved by technology

This not only prolongs the working time of the coating operation and reduces the efficiency, but also causes the on-site environment to be polluted by working media such as cement due to manual repairs, increasing the difficulty of subsequent cleaning work
In addition, the adhesion of the cement coating and the inner wall of the cast pipe to the cast pipe manufactured through this post-repair is also affected
[0004] In addition, considering that the plugging device needs to be used repeatedly, it is necessary to consider the erosion and deterioration of the plugging device by cement mortar. For example, the cement mortar enters the plugging device and is difficult to clean and deposits for a long time, corroding and deteriorating the plugging device

Embodiment Construction

[0025] Some possible embodiments of the present application are described below with reference to the accompanying drawings. It is noted that the figures are not drawn to scale. Some details may be exaggerated for clarity of presentation, and some details not necessarily shown have been omitted.

[0026] It should be noted that, in this application, the terms "axial" and "radial" are defined relative to the direction of the casting pipe, which is oriented with the central axis of the casting pipe. The use of "axial" and "radial" is descriptive (meaning only the relative orientation of the components) and not limiting in any way (ie, not referring to a particular direction). The terms "axially inboard", "axially inwardly" refer to the direction towards the casting tube. The terms "radially inward", "radially inward" refer to the direction towards the axis of the cast tube.

[0027] like figure 1 As shown, the present application discloses a partial cross-sectional view of a...

Abstract

The invention provides an inflatable rubber tire, a framework and a plug device for pipe coating and lining. The inflatable rubber tire comprises a rubber tire body, an inflation nozzle, a traction ring belt and at least one vent hole. The framework comprises an L-shaped component and an I-shaped component. The plug device comprises an inflatable rubber tire and a framework. When the framework and the inflatable rubber tire are matched to be used for coating a pipe, a coating on the inner wall of the end face of the pipe can be prevented from being stuck off.

Description

technical field [0001] The present application relates to an inflatable rubber tire for lining pipes, especially cast pipes, a skeleton suitable for the inflatable rubber tire, and a plug device comprising the skeleton and the inflatable rubber tire. Background technique [0002] In the production process of cast pipe (cast iron pipe), in order to prolong the service life of the cast pipe and the cleanliness of the conveying medium, it is often necessary to form a coating layer on its inner wall. A common practice is to apply a cement coating with a thickness of more than 2mm. Usually, a plug device is used to seal both ends of the casting pipe; then the cement is injected into the casting pipe, and through the high-speed rotation of the casting pipe, the centrifugal action is used to make the cement slurry gradually form on the inner wall of the casting pipe with a uniform thickness, a certain hardness and Adhesive cement coating, water may be precipitated during this proc...
