Ultra-large prefabricated pipe joint production and construction process

Abstract

The invention provides a production and construction process for an ultra-large prefabricated pipe joint, and belongs to the technical field of prefabricated pipe joints, the production and construction process for the ultra-large prefabricated pipe joint comprises the following steps: step 1, mounting reinforcing steel bars through a movable plate and a fixed plate, and conveying the reinforcing steel bars into a pouring cavity through a conveying device; secondly, cement is injected into the pouring cavity through the pouring opening, and the cement is waited to be condensed; thirdly, after the cement is completely condensed, a hydraulic cylinder is started to drive a bottom mold to move downwards, the bottom mold moves downwards to push a top mold to move upwards through a lifting mechanism, and the prefabricated pipe joint is demolded; and fourthly, a supporting plate is driven to move through a moving mechanism, so that the supporting plate moves the prefabricated pipe joint to the exterior of the pouring cavity, and finally the prefabricated pipe joint is unloaded. According to the device, a prefabricated pipe joint can be automatically demoulded through movement of the top mould and the bottom mould, and the prefabricated pipe joint is moved to the outside of the pouring cavity through the moving mechanism, so that the prefabricated pipe joint is more convenient to unload.

Description

technical field [0001] The invention belongs to the technical field of prefabricated pipe sections, and in particular relates to a production and construction process for super-large prefabricated pipe sections. Background technique [0002] With the acceleration of the construction of urban underground comprehensive pipe gallery, the prefabricated concrete comprehensive pipe gallery has been raised to an unprecedented height. The standard section of the underground integrated pipe gallery is assembled by prefabricated pipe sections. The prefabricated pipe sections can be produced in the prefabricated parts factory. In order to facilitate the production of super large prefabricated pipe sections, the complete prefabricated pipe section needs to be divided into two parts. Part of the prefabricated pipe sections are spliced ​​into a complete prefabricated pipe section for use. [0003] When the existing prefabricated pipe section is poured, it is very inconvenient to demold t...
