Description

Straight-through concrete drain pipe manufacturing system and drain pipe manufacturing method Technical Field The invention relates to the technical field of pipeline systems, in particular to a straight-through concrete drain pipe manufacturing system and a drain pipe manufacturing method. Background The concrete drain pipe is an important component in urban and rural drainage systems, and for convenience of construction, most of the existing concrete drain pipes are directly processed and formed in factories and conveyed to construction sites for paving, and in terms of production modes, the existing concrete drain pipes are generally formed by casting concrete through a mould for maintenance. The existing concrete drain pipe production mode specifically comprises a bottom plate, a cylindrical inner mold is vertically fixed on the bottom plate, when concrete pouring is carried out, an outer ring of the inner mold on the bottom plate is required to be assembled with a cylindrical outer mold, a pouring gap is formed between the outer mold and the inner mold, concrete pouring work is carried out, concrete molding is waited after pouring is completed, demolding is carried out, however, the existing concrete drain pipe production mode has certain defects, on one hand, when demolding work is carried out, the outer mold can be easily torn off from the outer ring of the drain pipe, but because the inner mold is in a complete cylindrical shape, the inner mold is required to be integrally pulled out from the drain pipe when demolding is carried out, even if demolding agent is smeared on the inner mold, demolding work is still difficult, particularly when the length of the drain pipe is longer, after the outer mold is required to be removed, the inner mold, the bottom plate and the drain pipe are required to be integrally lifted, and the inner mold can be smoothly broken by a hammer to knock the bottom plate, meanwhile, the demolding mode has certain danger, and a lifting tool for falling off or lifting during knocking can possibly cause production accidents or damage to the drain pipe structure. On the other hand, the vertical pouring mode is difficult to perform due to the annular gap at the upper pouring position, and the drain pipe is generally transversely arranged in the process of transportation or storage, the vertical pouring mode is generally carried out at the middle parts of two sides (but not two ends) of the drain pipe during demolding, and after the demolding of the inner mold is completed, the drain pipe can turn over even due to the weight difference of the two ends, so that certain potential safety hazard exists.
