Railway protection fence, wire rolling cage

(1) The barbed wire rolling cage is fixed with the barbed wire connecting card every 120 degrees after the adjacent two circles are circled by the blade barbed wire. After closing, the diameter of the barbed wire rolling is 50cm. After opening, the installation spacing of each cross ring is 20cm, and the diameter is not less than 45cm.

(2) The stabbing rope of the blade is made of punching steel plate and mechanically rolled on steel wire. The width of the stabbing is 22mm, the vertical distance of the blade is 15mm, the longitudinal distance of the stabbing is 34mm, and the diameter of the core wire is 2.5mm. Q195 steel plate net with blade thickness of 0.5mm is made by punching. The core wire is cold drawn from HPB300 φ 6.5mm high wire.
 
(3) the wire connection buckle is connected with the longitudinal tendons fixed on the bracket. The longitudinal reinforcement and the support are connected by cold-drawn galvanized steel wire with φ 2.5mm circling twice and then tightened and fixed. The support is arranged in the column and the middle position of the span 3m protective fence, in which the span is set and the upper part of the column, the support and the protective fence are connected by the bracket hoop, for the protective fence that has been installed with metal mesh. The wire rolling cage is directly fixed on the metal mesh horizontal piece and wire with φ 2.5mm cold-drawn galvanized steel wire or wire connection buckle.

(4) The vertical distance between the lower edge of the barbed wire rolling cage knife and the upper edge of the reinforced concrete protection fence is 0.05m.
The amount of galvanized wire rolling cage is 120g/m2 in general environment, and 270g/m2 in special environment. Longitudinal tendons and cold-drawn steel wires need hot-dip galvanizing, and the amount of galvanizing is 270g/m2.
