Mechanized molding process for prefabricated component

Abstract

The invention discloses a mechanized molding process for prefabricated components and belongs to the field of mechanized molding process. The mechanized molding process for prefabricated components includes the steps of blank template making, steel bar binding, template installation, concrete pouring, pre-stressed tendon tensioning and channel grouting; the blank template making involves blank template mounding, press calendering, separant coating and position line arrangement; the concrete pouring involves pouring, vibrating, smoothing calendering, maintenance and pipe unloading; and the pre-stressed tendon tensioning involves screw end rod welding, pre-stressed tendon mounting, base plate mounting, tensioning and steel bar anchoring. According to the mechanized molding process, after thepipe unloading and before the screw end rod welding, a slag cleaning process is required; a diameter-variable cleaning device is configured in the slag cleaning process; a scraping head can be selected according to the diameter of channels; tightly adhered debris inside the channels are scraped off at first, and then, the scraped debris is completely removed from the channels; and therefore, a cleaning effect is significantly improved, and a good foundation is laid for subsequent construction process.

AI Technical Summary

Problems solved by technology

[0004] In the mechanized forming process of prefabricated components, there is a simple but non-negligible small process, that is, to clean the tunnel after the pumping is completed. There is no special tool for cleaning the tunnel in the existing construction technology, and generally a simple iron wire Cotton silk is wrapped around the end of the hole, and it is inserted into the hole for simple cleaning. This cleaning effect is poor, especially for some debris that adheres tightly. Hung up by sundries and left in the tunnel, affecting the subsequent construction process
