An interlocking modular smart seawall diversion and recreation system provides step-shaped diverter sections arranged side-by-side along a shoreline. The diverter sections slope from a base end up towards an upper end. To break kinetic energy of waves, and divert waves, the diverter sections form steps with curved risers and horizontal treads. The system forms a diversion path for the waves that reach the upper end of the modular walls and recirculate the wave energy back to divertor chamber and natural environment. Foundation pilings project into the ground and extend up to support the wall sections. The bottom end of foundation pilings terminates at sheared attachments having a tapered cross section and an edge for securely anchoring into the ground. A platform atop the diverter sections provides a pathway; a lighted platform for recreational activities; and transparent skylight portals for observing aquatic wildlife in water below and creating an indigenous ecosystem.

A multifunctional floating breakwater includes: a plank platform, a first buoy, a second buoy, a first wave baffle, a second wave baffle, a first arc breast wall, a second arc breast wall, upper inclined supports, lower inclined supports and a net cage. The multifunctional floating breakwater integrates a floating breakwater and a wave-energy power generation device, which can not only maintain good stability of the water surface in a harbor, but also generate electric energy, and allow for aquaculture and other activities as well, and has advantages of being movable and not limited by water depth and geology. In addition, the invention has a simple structure, easy production and maintenance, no pollution to the marine environment and therefore wide application prospects.

Proposed is a construction method for an underwater concrete block structure. The concrete block structure is formed by stacking a plurality of concrete blocks on a foundation concrete block structure by using a guide pipe, and a concrete column is formed by, before removing the guide pipe, inserting a concrete column forming set such as a waterproof membrane through the inside of the guide pipe, so that the waterproof membrane can be inserted conveniently and safely and the construction speed of the concrete block structure can be further improved.

A movable platform adjacent to a stationary platform and operable between a raised position forming a part of a deck surface and a lowered position at least partially submerged in the body of water. A landing section and walkway section included in the movable platform. A lever arm carried by the landing section and extending underneath the walkway section, wherein the lever arm engages a bottom side of the walkway section when the movable platform is in the raised position, and the lever arm disengages from the walkway section when the movable platform is in the lowered position. A floatation unit disposed on the bottom side of the landing section. An air pump unit carried by the stationary platform, wherein the air pump unit channels air into and out of the floatation unit to change the buoyancy of the floatation unit to raise and lower the movable platform.

A pile guide has a collar with a void therein. A planar flange extends from a side of the collar. A bracket has opposing guides constructed and arranged for receiving the planar flange of the pile guide therein. The planar flange is in a slidable relationship with the bracket, and the bracket is constructed and arranged for mounting to a floating dock. The distance of the collar from the floating dock can be adjusted to accommodate for distances of piles from the floating dock.
