Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a drainage pipe hole blocking device. Background Art

[0002] At present, after the completion of the primary structure construction, after the secondary structure construction and the installation of the drainage pipe, it is necessary to use concrete mortar to seal the drainage pipe installation hole. Generally, a template is set at the bottom of the drainage pipe hole on site, and then the template is fixed by pushing down or pulling up. Since the template is located at the top of the lower building, the height is high and the space is small, it is inconvenient to use general wooden templates for installation and disassembly. Using steel pipes to return the top will cause the template to be uneven and slurry to leak. Utility Model Content
