You need to override getValidatorInstance method in your Request class, for example this way:

protected function getValidatorInstance()
{
    $validator = parent::getValidatorInstance();
    $validator->addImplicitExtension('numericarray', function($attribute, $value, $parameters) {
        foreach ($value as $v) {
            if (!is_int($v)) {
                return false;
            }
        }
        return true;
    });

    return $validator;
}
