Query: Kaluza--Klein-type models of de Sitter and Poincar\'e gauge theories of
  gravity   We construct Kaluza--Klein-type models with a de Sitter or Minkowski bundle
in the de Sitter or Poincar\'e gauge theory of gravity, respectively. A
manifestly gauge-invariant formalism has been given. The gravitational dynamics
is constructed by the geometry of the de Sitter or Minkowski bundle and a
global section which plays an important role in the gauge-invariant formalism.
Unlike the old Kaluza--Klein-type models of gauge theory of gravity, a suitable
cosmological term can be obtained in the Lagrangian of our models and the
models in the spin-current-free and torsion-free limit will come back to
general relativity with a corresponding cosmological term. We also generalize
the results to the case with a variable cosmological term.
