FIELD: construction.
SUBSTANCE: this arch consists of load-bearing oval tubes delineated by parabola, tightening tube, suspension and triangular grate. Proposed method consists in that arch skewbacks rest on load-bearing beds of two columns to couple the latter with top belt with heads of columns. Flexible concrete lies are connected to arch tubular elements pipes. Pump station control board is used to force and inject, from top to bottom, the fine expanding concrete into the arch tubular cavities. Every arch gets transformed from two parabolic triangles to monolith composite arch structure. Said structure is pre-stressed by aforesaid suspension. Turn-buckle makes a stressing element.
EFFECT: lower material input.
