METHOD FOR CRANELESS SUPPORT SUPERSTRUCTURE INSTALLATION WITH BRACES Russian patent published in 2019 - IPC E01D19/14 

FIELD: construction.

SUBSTANCE: invention relates to the field of bridge construction. In method of craneless installation of superstructure to head beams there are pivotally attached two spacers of required length and strength, other ends of which rest on additional pontoon; two winches and a limiter are installed on the pile grillage of the foundation; as a means of delivering a superstructure from the IMI-60 property, a floating support with the required stability is provided, with supports, which are capable of retaining the superstructure in the half-horizontal state in size. Prior to installation of superstructure, floating platform is assembled from IMI-60. Supports are installed on the support. Crane from shore to floating support in semi-horizontal state superstructure is installed from property IMI-60 with two struts hinged to head beams, other ends of braces are fixed for additional pontoons. A winch and a limiter are installed on the grillage of the pile foundation. When floating platform with superstructure from IMI-60 approaches grid of pile foundation to lower ends of braces, ends of winches cable are attached. When winch limiter hits, traction force is caused, and superstructure changes from semi-horizontal to vertical state. After installation of superstructure in vertical state braces are disconnected.

EFFECT: possibility of craneless installation of superstructure on grillage pile foundation without separation of head beams and grillage.
