I'd recommend (besides of reading about generics and C# in general) to configure the pool with desired types on run time, store them in dictionaries and use the Type as key, i.e. something along the following lines...:

//...

// configuration, maybe factor out to a dedicated class...
private readonly IDictionary m_SupportedPools =
    new Dictionary();

// add this queryable, note that type inference works here
public void AddToPool(IQueryable p_Queryable)
{
    m_SupportedPools.Add(typeof(T), p_Queryable);
}

public IQueryable GetPool()
{
    IQueryable t_Set = null;  
    if (m_SupportedQueries.TryGetValue(typeof(T), out t_Set)) {
        return t_Set as IQueryable;
    } else {
        return null;
    }
}
