Multi-functional overwater movable lift-type work platform

The invention discloses a multi-functional overwater movable lift-type work platform comprising an upper-layer work platform and a lower-layer work platform which are movably connected. The lower-layer work platform is hung under the upper-layer work platform, both the upper-layer work platform and the lower-layer work platform are provided with spud legs used for supporting the work platforms on a seabed, and the upper-layer work platform is provided with a driving device which is slidably connected with the same. The lower-layer work platform is provided with a stop device capable of having the driving device limited. The multi-functional overwater movable lift-type work platform is applicable to construction under the condition of awful overwater waves, can be conveniently moved to a construction location according to requirements of marine engineering construction, and is unaffected by the waves, so that a construction period can be shortened and construction efficiency can be improved. The multi-functional overwater movable lift-type work platform is also applicable to construction regions such as shoals and swamps with insufficient water depth for ships, is convenient and flexible to move and wide in construction region coverage.
