CONSTRUCTION METHOD OF ORTHOGONAL THRESHOLD POWER PLANT (OTPP) COMBINED WITH SHIP PASSAGE (SP) Russian patent published in 2015 - IPC F03B13/00 E02B9/00 

FIELD: power industry.

SUBSTANCE: at implementation of a construction method of OTPP combined with SP 1, all the component parts of the object being built in the form of ready-made reinforced concrete or metal blocks from the works to the assembly site are delivered by means of a float-on method. Sequence of construction work is started from an earlier installed supporting and restricting barrier consisting of a metal, reinforced concrete or wooden grooved pile projecting in an underwater position through the height sufficient for fixed retention of flooded threshold blocks with orthogonal turbines 4, including foundation of SP 1. First, assembly of the foundation is started by afloat attachment into a common structure of a rectangular shape, the margin of buoyancy of which is sufficient for retention of posts for laying of board panels. Assembly of SP 1 is completed by installation of double-leaf gate 7. Gate 7 is left open till completion of work on installation of threshold blocks with turbines 4 connected through shafting 5 to generators 6 installed on the shore.

EFFECT: construction of HPP on navigable rivers, where it is impossible to erect dams and flood gates as per local conditions.
