Is any way to force create crawled properties using PowerShell for site collumns without having any content in this fields ?

This is possible (at least using on-prem version of SharePoint).
Using a PowerShell admin console, you can use New-SPEnterpriseSearchMetadataCrawledProperty:
New-SPEnterpriseSearchMetadataCrawledProperty -Name $crawledProperty.Name ` -Category $crawledProperty.CategoryName ` -VariantType $crawledProperty.VariantType ` -PropSet $crawledProperty.PropSet ` -IsMappedToContents $crawledProperty.IsMappedToContents ` -IsNameEnum $false ` -SearchApplication $SearchApplication Some arguments aren't obvious. In order to help find this values, I suggest you to export an existing one (in a design site collection for example):
Get-SPEnterpriseSearchMetadataCrawledProperty | ? { $_.Name -match "ows_YourField" } You can even build more complex scripts that exports crawled properties, managed properties and mappings regarding a field name prefix (a good practice!) into a cv file or similar, then reimport them at the target.
