FIELD: construction. ^ SUBSTANCE: guard breakwall, mainly for yacht ports, includes separate sections, vertical walls, anchor traction rods and prism of cobble fill. Separate sections are arranged in the form of precast monolithic support and intermediate sections installed serially one after another with alternation in a single row. Each support section is installed along longitudinal axis of breakwall structure at the distance equal to length of intermediate section. Intermediate sections are installed as displaced relative to this axis towards open water area to form internal space between support precast monolithic sections. Each support precast monolithic section is equipped with retaining metal frame with cobble fill, at the specified distance from which at external sides there are barrier elements to make it possible to concrete internal space between retaining metal frame and barrier elements. Each intermediate precast monolithic section is arranged of vertical external wall and parallel vertical internal wall installed at the specified distance, and internal space between them is concreted. External and internal vertical walls are made of external and internal panels installed one onto another, accordingly, besides vertical external and internal panels are first connected to each other by temporary anchor rods, then by permanent anchor rods. On top of two neighbouring support precast monolithic sections there are longitudinal reinforced concrete connection elements installed as resting with two ends on them and covering internal space between neighbouring precast monolithic sections. Top of two neighbouring support precast monolithic sections and intermediate precast monolithic section arranged between them, and also longitudinal reinforced concrete connection elements arranged between support precast monolithic sections are concreted to form precast monolithic reinforced concrete slab, which rigidly connects the first neighbouring support precast monolithic sections with intermediate precast monolithic section arranged between them to form the first root precast monolithic section, and subsequent precast monolithic sections downstream the first root section consist of one support precast monolithic section and one intermediate precast monolithic section, at the same time the last precast monolithic section is the head one in direction of the coast. All precast monolithic sections, starting from the first root and ending with the last head one, are arranged serially one after another and adjoin each other to form a single structure of guard breakwall, along length of which a reinforced concrete superstructure is installed as resting onto precast monolithic reinforced concrete slab. ^ EFFECT: improved reliability of breakwall design, reduction of material intensity. ^ 4 cl, 4 dwg |
