A kind of preparation method of concrete pipe with rubber ring groove

Abstract

The invention provides a manufacturing method of a concrete pipe with rubber ring grooves. The manufacturing method includes the steps that firstly, a spigot forming ring composed of multiple ring petals is installed on a bottom support of a core mold vibration pipe making machine, and then the multiple ring petals are tightly tied together through a steel belt; secondly, a reinforcing steel bar framework is placed on the bottom support; thirdly, an outer mold is installed on the spigot forming ring in a sleeving manner, the lower portion of the inner wall of a socket steel sleeve is connectedwith height control hooks, the upper portions of the height control hooks are made exposed out of the top end of the socket steel sleeve, height control stop pieces are arranged on the top of the outer mold, the socket steel sleeve is inserted in the outer mold, the height control hooks are supported through the height control stop pieces, and therefore height positioning is conducted on the socket steel sleeve; and fourthly, the socket steel sleeve and the reinforcing steel bar framework are fixedly connected, the height control hooks are then detached, the core mold vibration pipe making machine is started, concrete is poured, and the concrete pipe can be obtained through curing after pouring is completed. By means of the method, the size and the shape of a connector of the concrete pipe can both meet design requirements, and the finished product rate of products can be effectively increased.

Description

technical field [0001] The invention relates to a method for preparing a concrete pipe with rubber ring grooves. Background technique [0002] At present, the anti-seepage of reinforced concrete pipe joints is a difficult problem in the industry. Various scientific research institutes and manufacturers have been researching and exploring which method to use. At present, it is believed that setting apron grooves at the socket ends of reinforced concrete pipes, especially double apron grooves, has the advantages of The sealing effect of the interface is reliable, the construction is convenient, the monitoring of the sealing effect is simple and many other advantages, and it is often used in projects with high quality requirements. [0003] Mandrel vibration pipe making machine is used to produce concrete pipes by mandrel vibration process, which has been relatively popular in my country's cement product industry. Compared with other processes, the use of mandrel vibration proc...

Problems solved by technology

In order to facilitate demoulding, the spigot forming ring is designed as a multi-ring valve, and the bottom of the ring valve is provided with installation holes, and the ring valve is installed on the bottom bracket of the mandrel vibrating pipe making machine through the pin shaft inserted into the installation hole. With the injection of concrete, the concrete will press the bottom ring valve, especially the upper part of the ring valve is easy to open outward, and the socket size of the concrete pipe is easy to be too large and deformed, resulting in unqualified products, or during construction. Interface installation is difficult, which is also a common problem faced by the industry
