Description
Technical field
The utility model relates to a kind of catenary mast, and especially a kind of catenary mast of being made by RPC is specially adapted to all kinds of bridges, highway constructions such as railway, highway, municipal administration.
Background technology
With the railway traffic is example, railway bed, bridge are multi-specialized integrated system engineerings, relate to building structure, rail system, power system, communication and signal system etc., modern electric railway roadbed technical level height, complex structure, relate to many professional domains, the large-sized concrete structural element required increasingly stringent, raising.
Catenary mast is one of important ancillary facility of railway electrification circuit, and it is for power being provided, guaranteeing that safe train operation has important function.The manufacturing materials of catenary mast and form of structure have material impact to load, structure, durability, safety assurance effect and the landscape effect of roadbed bridge.Whole loads of contact suspension, support and positioner are being born on catenary mast and basis thereof, in case come in contact net pillar fracture accident, will directly cause contact net to collapse, and then cause power failure, circuit to stop up, if can not get timely processing, very likely cause great driving accident.Therefore in daily railway contact line management, emphasis has been strengthened monitoring, detection and the maintenance to catenary mast, guarantees that with all strength it is in good condition normal.
The railway contact line pillar mainly adopts ferroconcrete prop and steel strut at present.
Though ferroconcrete prop is cheap, owing to limit by the characteristic of Reinforced Concrete Materials itself, make ferroconcrete prop comparatively heavy, physical dimension is bigger, has increased load or space on the roadbed bridge; Because present ferroconcrete prop adopts batch production prefabricated struts assembly mostly, adopts field-installed mode then, when bullet train passes through, can produce certain vibrations, year in and year out, strut assemblies can be become flexible, damaged even fracture, influences traffic safety; Ferroconcrete prop needs frequently to change because the limitation of its structure and the performance characteristic of ordinary concrete material make that the maintenance workload of this kind pillar is bigger, and the later maintenance expense is higher; And under present steel concrete production technology level, make that the landscape effect of this kind pillar is relatively poor relatively.
That steel strut has is in light weight, capacity is big, anti-collision, transportation and advantage such as easy for installation; Steel using amount is big, cost is high, one-time investment is big but exist, poor corrosion resistance, and it is anticorrosion regularly to eliminate rust, paint, and makes its maintenance expense height, and peeling off, influencing of face coat lacquer is attractive in appearance, and shortcoming such as inconvenient maintenance is arranged.From saving steel and making things convenient for the angle of operation maintenance, require few as far as possible the employing.
In addition, above-mentioned two kinds of materials all consume non-renewable resources in a large number, and manufacturing process energy consumption height, CO2 discharge value are big, are unfavorable for environmental protection.
Because the defective that above-mentioned known technology exists, the design people develops RPC catenary mast of the present utility model according to the production design experiences of being engaged in this area and association area for many years.
