COFFRAGES PNEUMATIQUES
to built at site the concrete pipelines.
DIAMETERS from 150 mm until 4000 mm
Use of
pneumatic form |
The pneumatic form (diameters from 150 up to 4000 mms, lengths until 30 m and more) can be usefor the direct construction on site of concrete pipings such that sewage systems, water delivery and so on sewer.

Advantages
to use
pneumatic form |
Inflated with the compressed air, the pneumatic form constitutes the cylindrical body around of which the pipeline in concrete is casted, (with the help of wooden form, if needed). After the concrete become hard (12 hours approximately), the form is deflated, easely removed and remain ready for the next works. Its easyness and its rapidity of job, the very low surface roughness and its lack of adhesion to the concrete (of where a very great facility to remove it) permit to use with a very reduced manpower. It is proposed under 2 formulas: sale or renting (for works of small and medium length). He/it satisfies therefore entirely to requirements of quality and profitability of Public Works compnies. |
