Title:
UNDERWATER CONCRETE STRUCTURE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/035961
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problems of enabling production of a formwork such that a large crane vessel for suspending a concrete structure is not necessary, mechanical pre-stress can be introduced via tendons, and use underwater is possible without any problems, and enabling the production of an underwater concrete structure such that work to remove the formwork is not required because the formwork is made of concrete and serves as the surface material of the structure. [Solution] This underwater concrete structure manufacturing method is characterized by using tendons to introduce mechanical stress into a concrete abutment formwork in which side wall parts of a concrete hollow structure that face each other act as abutments, at least part of the hollow concrete structure being open at an upper part or a side part; filling the interior of the formwork with concrete; and solidifying the concrete.
