Workflow

I want send approval request to approver if he didnot approve within 2 days then approval will sent to approvers manager and then anyone of them can approve the request

Would NOT recommend generating new approvals as a reminder.
I'd recommend the following flow activities

1) create approval for approver
2) wait 2 days
3) if ( 1 ) is still requested...
4) Send reminder notification to ( 1 )'s approver
5)  Create approval for approver's manager.
6)  If ( 1 ) or ( 5 ) are approved continue with your flow.
