The standard steel sheet pile driving methods include impact drive, vibration drive and hydraulic pressing. Are these methods applicable to PVC sheet stacks and synthetic sheet stacks?
The standard piling rigs and tools for FRP and vinyl sheet pile driving as previously claimed by some sheet pile manufacturers. Although vinyl sheet piles have a significantly lower modular elasticity compared with other materials, in particular stainless sheet piles, they have been tested and are suitable for common driving techniques.
They are currently used to cater to the increasing project requirements in different regions in enormous amounts. In construction of bulkheads and containment barriers, vinyl sheet-piles are increasingly popular.
In addition, a case study was also presented from the above report, which showed that plastic batteries were driven during drainage. A very important remark was made as follows:
The flexibility of sheet piles resulted in a considerable bending during the operation of a single pile. This was not a problem if the piles were pulled as a pair and there were probably further improvements if there was more support for the batteries.
It appears that there is no difference at all between plastic sheet piles and other sheet piles. Mandrels are best for the side or front. This is a shaped stainless steel element identical to the vinyl pile rammed. The length of the mandrel shall correspond to the length of the rammed PVC items.
We recommend three main types of mandrels all specially made out of steel, following the overall profile of the pile of the PVC profile. The sleeve, slurry and chicken are sleeves.
The driving capacity of vinyl sheet piles is enhanced by a guide structure or template, like any other material. For each pile or pair of piles, several contractors recommend using at least two templates. Guide or waling holds the pile of sheets in place and templates should also be used for correcting the plumbing of the pile of sheets.
Vinyl sheet piles may have difficulty penetrating difficult ground conditions such as very compact, coherent or coarse granular soils, as they are lightweight. Jetting is used in these cases to make driving easier. This process causes pressure directly below the installed piles, loosening and removing the soil or obstacles. This technology applies special water or air ejectors.
Finally, some
companies have been able to develop special systems like the hydraulic
"Silent Piler" from Japan as an ultimate plastic sheet piling
solution to reduce stresses on the vinyl sheet piles. Most barriers and
difficulties are probably eliminated in this scenario when plastic sheet piles
are driven. Reach us at Bigfoot if you are looking for a sheet pile manufacturer in OKC.
