Problems solved by technology

[0003] The purpose of the present invention is to provide a maintenance structure and maintenance method for reinforced concrete drainage pipes formed by suspension rollers, which mainly solves the problem that the existing concrete slump requirements are high, and the suspension rollers cannot leave the suspension roller shaft immediately after forming, and need to stop on the suspension roller shaft For a period of time, and it is not easy to control the static stop time and other issues

Embodiment 1

[0025] Such as Figure 1-4 As shown, the suspension roller forming reinforced concrete drainage pipe maintenance structure includes a reinforced concrete drainage pipe steel mold 2, a steel cylinder 3 located inside the reinforced concrete drainage pipe steel mold 2 and extending from both ends of the reinforced concrete drainage pipe steel mold 2, The steel cylinder is used to be sleeved on the suspension roller shaft 4 of the suspension roller machine 1, and also includes a movable support 5 for static stopping after the suspension roller is formed, and a group of movable supports 5 are set according to a drain pipe in the maintenance area. In this embodiment, the movable support 5 is a support with a symmetrical upper arm that can rotate by 90°, including a support 8, a rotating shaft 7 arranged on the top of the supporting frame 8, and a movable arm 6 that rotates on the rotating shaft and is used to support the steel cylinder.

[0026] The steel cylinder is a cylindrical ...

Abstract

The invention discloses a novel suspended roller forming reinforced concrete drainage pipe maintenance structure and a maintenance method thereof. The maintenance structure comprises a reinforced concrete drainage pipe steel mold, a steel cylinder and a movable support used for static stop after a suspended roller is formed, wherein the steel cylinder is arranged in the reinforced concrete drainage pipe steel mold, and the two ends of the steel cylinder stretch out. The maintenance method includes the steps that firstly, before the suspended roller is formed, a suspended roller shaft is sleeved with the steel cylinder, and the steel cylinder replaces the suspended roller shaft to roll the inner wall of the reinforced concrete drainage pipe steel mold; secondly, after a pipe body is formed, the static stop process is omitted, the reinforced concrete drainage pipe steel mold and the steel cylinder are directly lifted off a suspended roller machine, the steel cylinder serves as the support to be hung for maintenance, and the steel cylinder is suspended on the movable support. The concrete slump value is effectively reduced, the suspended roller can be immediately away from the suspended roller shaft after being formed, static stop is not needed, the displacement phenomenon caused by the gravity effect of top end concrete before the top end concrete is in a condensation state can be effectively reduced, and production quality is guaranteed while production efficiency is improved.

Description

technical field [0001] The invention relates to a maintenance structure and a maintenance method for a reinforced concrete drainage pipe formed by suspension rollers, and belongs to the field of building construction. Background technique [0002] The production of reinforced concrete drainage pipes formed by traditional suspension rollers is to pour dry hard concrete with a Weibo consistency of 5-10(s), which is formed by centrifugal rolling of the suspension roller shaft through the rotation of the suspension roller shaft and the weight of the steel mold and concrete. It has the characteristics of high requirements on concrete slump, the suspension roller cannot leave the suspension roller shaft immediately after forming, and needs to stop at the suspension roller shaft for a period of time, and it is not easy to control the static stop time. If the concrete slump is too large, the time to stop on the suspension roller shaft will be longer, and the concrete slump and displ...
