Description

Bridge cable protection combination sheath

Technical Field

The utility model relates to a bridge engineering field, concretely relates to bridge cable protection combination sheath.

Background

The bridge cable system is a main bearing structure of a suspension bridge, a cable-stayed bridge and an arch suspension bridge, but is in a severe working environment (moisture corrosion, wind erosion, stress corrosion and the like) crossing rivers, lakes and seas; when an accident occurs, a bridge is easy to catch fire, cable deformation and even bridge body collapse are caused, and once the cable is damaged and failed, serious safety accidents and economic losses can be caused. Therefore, in order to ensure the safety of the bridge structure, the cable is required to be protected. Japanese uses a modified putty material (HS) consisting of calcium plumbate, high molecular organic lead, etc., thus constituting a protection system: acrylic resin primer, HS putty winding and chlorinated rubber finish. The domestic protection system is developed for many years, and the key problems that the service life of a cable is shortened and the like are caused by the fact that a high-strength composite adhesive tape is wound outside a steel wire and then a PE layer is hot extruded are solved from the prior protection system that glass fiber cloth is wound and coated with epoxy resin and three layers of glass cloth are wound and coated after asphalt is coated at first to the prior protection system that a high-density Polyethylene (PE) layer is hot extruded outside a galvanized steel wire.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bridge cable protects combination sheath to solve the problem that proposes in the above-mentioned background art.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

the utility model provides a bridge cable protects combination sheath, is including first protective member and the second protective member that can splice into complete sheath main part, first protective member and second protective member are the semicircle cell type shape component that compound stack material layer mould pressing was made, compound stack material layer sets up with high temperature resistant silicone resin layer interval in turn for 3 ~ 5 layers fire-retardant resistant weather resistant fabric of preventing fires and forms, the outer winding of sheath main part has the PE layer, and the PE layer overcoat has anticorrosive coating.

Preferably, the fireproof flame-retardant weather-resistant fabric is high silica cloth, basalt fiber cloth, glass fiber cloth or carbon fiber cloth.
