Manufacturing technique of reinforced concrete drain pipe

Abstract

The invention discloses a manufacturing technique of a reinforced concrete drain pipe, which is characterized by comprising the following technical steps: firstly manufacturing a reinforced skeleton according to the size of the reinforced concrete drain pipe and manufacturing an F steel ring; next, putting the F steel ring on a bottom mold and connecting the manufactured reinforced skeleton and the F steel ring; then sheathing the bottom mold and the reinforced skeleton into an outer mold and connecting the outer mold and the bottom mold; then sheathing the outer mold outside an inner film ina pool pit and installing a socket mold at the upper end surface of the outer mold; then injecting concrete and adopting a pneumatic brake for vibration; after injecting concrete, respectively removing the socket mold, an inner mold and the outer mold; sheathing the demolded reinforced concrete drain pipe on a steam cover for steaming and molding; and finally removing the bottom mold. Compared with the prior art, the manufacturing technique improves production efficiency and saves cost.

Description

technical field [0001] The invention relates to a manufacturing process of a drainage pipe, in particular to a manufacturing process of a reinforced concrete drainage pipe. Background technique [0002] Due to the characteristics of high hardness, compressive strength, corrosion resistance and high temperature resistance, reinforced concrete drainage pipes are widely used in various harsh environments, such as water conservancy projects and sewage projects. At present, when most reinforced concrete drainage pipes are manufactured, because the concrete is relatively wet, the reinforced concrete drainage pipes must be steam-cured and shaped first, and then removed from the mold, otherwise the drainage pipes will easily collapse; however, it takes four hours to perform a steam-curing process Right or left, according to this manufacturing process to produce reinforced concrete drainage pipes, one set of molds can only produce two pieces of reinforced concrete drainage pipes a da...

Problems solved by technology

At present, when most reinforced concrete drainage pipes are manufactured, because the concrete is relatively wet, the reinforced concrete drainage pipes must be steam-cured and shaped first, and then removed from the mold, otherwise the drainage pipes will easily collapse; however, it takes four hours to perform a steam-curing process About, according to this manufacturing process to produce reinforced concrete drainage pipes, a set of molds can only produce two pieces of reinforced concrete drainage pipes a day, so the output is very low. If you want to increase the output, you must increase the number of molds, and the cost is very high.

When manufacturing reinforced concrete drainage pipes, most mechanical pipe machines are used to vibrate and extrude the mold to make the concrete in the mold vibrate and extrude; however, this type of mechanical pipe machine has a complex structure and high cost

Therefore, there are still deficiencies in the existing manufacturing process of reinforced concrete drainage pipes, and it is necessary to improve to meet the needs of manufacturers.
