Description

Technical Field

[0001] The utility model relates to the technical field of short pipe moulds, in particular to a manufacturing device for a steel cylinder concrete short pipe. Background Art

[0002] At present, according to the current national standard (GB / T19685-2005), the standard length of the short pipe used in the pipeline is 5m or 6m. However, in actual engineering use, the accuracy of the fixed position setting of the pipeline is poor, and the length between adjacent fixed positions is not necessarily the standard length of the short pipe. In order to meet the actual use needs, the length of the short pipe is bound to be longer or shorter than the standard length. Non-standard short pipes bring great trouble to the production of short pipes. 1. If steel pipes are used to make short pipes, the project cost will increase and the daily inspection and maintenance of the pipeline will become complicated; 2. If PCCP short pipes are used, the device used by the manufacturer to cast and make PCCP short pipes is different from the mold device used to cast PCCP standard pipes. Special mold devices need to be customized according to the actual length of non-standard pipes, but such mold devices have low utilization rates and poor versatility for manufacturers, which is a serious waste of resources.

[0003] However, there are still some problems when using the existing short tube mold:
