over the Dnieper River in Kiev
ones with high-strength friction bolts of 22 mm diameter, the sealing of which is to
be made using Sikaflex silicone sealant.
As for the design solution of the bridge road part, it consists of an orthotropic deck,
welded cross-beams of double-T shape of equal height between the main girders and
of variable height outside, and of the main box-section girders. The pitch of the
cross-beams is 3.1 m, which are fastened to the main girders using top cover plates
with high-strength bolts in one level. On the bridge, on both sides of the driveway,
metal overhead contact-line supports are also provided with a pitch of ≈ 21.7 m.
The guardrails «Bridge guardrail H4B» are taken of company SGGT (Germany)
with a pitch of 1.1, 1.14 m high (at service passage) and 1.54 m (railway side), it
is made of galvanized steel. Guardrail posts are fastened to the superstructure with
M20 bolts. The steel grade of the guardrail parts is Ct3pc5 and Ct3cp5 according
to GOST 14637-89.
Railings 1.1 m high are located on the service passage. The pitch of the posts of
80 × 60 × 7 mm section makes 1.5 m, the handrail dimensions are 100 × 70 ×
5 mm, the lower and upper stringers are 50 × 30 × 3 mm, and the filling is 20 × 20
