Technical Field

The utility model belongs to the technical field of the production and processing equipment of circular culvert and specifically relates to a can demolish circular culvert inside and outside mould casting mold fast.

Background

The prefabricated vibration method for circular pipe culvert features use of internal and external cover moulds, inserted vibration and efficient additive. The mold can be immediately demoulded after molding, so that the turnover of the mold is accelerated; the reinforcing steel bar protective layer adopts the cushion block, and is better controlled. The traditional formwork and hoisting process affects the demolding and hoisting of the pipe joint, which results in damage to the end of the pipe joint and the hoisting position and other common problems and affects the appearance quality. The centrifugal prefabrication method which is widely applied at present still has the defect that a steel bar protective layer is difficult to control, so that the circular pipe culvert is inconvenient to produce.

In view of the above-mentioned defects, the present designer actively makes research and innovation to create a casting mold capable of rapidly removing the inner and outer molds of the circular pipe culvert, so that the casting mold has industrial utilization value.
