Abstract
The utility model provides a transparent cable convenient to durability disease detection, includes the cable, the total length within range or the steel tendon skin in the subregion of cable cover the transparent macromolecular material coating who has certain thickness to form entirely transparent and subregion transparent cable sheath, this cable sheath can satisfy cable sheath mechanical properties and durability, and the cable sheath can completely cut off the outside air, can slide between cable sheath and steel tendon. The utility model discloses a transparent cable material cost is low, and the preparation process is comparatively simple, easily batch production to have the advantage of direct observation to the steel tendon corrosion condition. Cross transparent cable sheath can observe directly perceivedly the durability disease condition such as steel tendon corruption in cable total length within range or the subregion, fracture.
Description
Technical field
This utility model relates to civil engineering and bridge field, is specifically related to a kind of transparent drag-line being easy to lasting hazard detection.
Background technology
Drag-line is as the main supporting member of Longspan Bridge (cable-stayed bridge, arched bridge pre-stressed boom etc.), using in the phase up to decades, under the coupling of the disaster factors such as the long term effect of environmental attack, material aging and load, fatigue effect and mutation effect, will inevitably lead to the damage accumulation of structure and system and degradation resistance, thus resisting the ability decline of natural disaster, even normal load effect, under extreme case, cause catastrophic burst accident.The service life of Longspan Bridge, stability and safety evaluation have important references meaning by drag-line steel tendon lasting hazard situation, for this, a kind of transparent drag-line being easy to lasting hazard detection of our utility model.Transparent drag-line is divided into all-transparent drag-line and partially transparent drag-line two class, adopt solidification macromolecule layer in drag-line length range or steel tendon surface, subregion forms transparent protective sleeve of pulling cable, steel tendon and ambient atmosphere flowing in sheath are not only completely cut off, and meet protective sleeve of pulling cable mechanical property and life requirement, and can sliding between steel tendon.Transparent protective sleeve of pulling cable had both completely cut off air flowing, made steel tendon not easily corrosion in transparent sheath, can be observed and assess again the lasting hazard situations such as the corrosion of drag-line steel tendon, fracture of wire by transparent sheath, solve the lasting hazard test problems of drag-line.
Utility model content
The purpose of this utility model is in that to provide a kind of transparent drag-line being easy to lasting hazard detection, it is possible to the situation of visual inspection drag-line lasting hazard.
The technology that this utility model adopts is as follows: a kind of transparent drag-line being easy to lasting hazard detection, including drag-line, it is characterized in, steel tendon outer layer in the length range of described drag-line or in subregion is covered with certain thickness transparent polymer material coating, thus forming the transparent protective sleeve of pulling cable of all-transparent and subregion, this protective sleeve of pulling cable disclosure satisfy that protective sleeve of pulling cable mechanical property and durability, and protective sleeve of pulling cable can completely cut off outside air, and protective sleeve of pulling cable and steel wire interfascicular can slidings.
The cost of material is low for transparent drag-line of the present utility model, and preparation process is relatively simple, it is easy to batch production, and has the advantage observing directly steel tendon corrosion situation.Cross clear cured coatings and can observe in drag-line length range intuitively or the lasting hazard situation such as steel tendon burn into fracture in subregion.
Accompanying drawing explanation
Making steel tendon not easily corrosion in transparent sheath, protective sleeve of pulling cable is transparent in drag-line length range or subregion, can be observed intuitively in drag-line length range by clear cured coatings or the lasting hazard situation such as steel tendon burn into fracture in subregion.
Accompanying drawing explanation
Fig. 1 is the protective sleeve of pulling cable structural representation that subregion is transparent；
Fig. 2 is the protective sleeve of pulling cable structural representation of all-transparent.
Detailed description of the invention
Below according to Figure of description citing, this utility model is described further:
Embodiment 1
A kind of transparent drag-line being easy to lasting hazard detection, including drag-line 1, it is characterized in, steel tendon outer layer in the length range of described drag-line or in subregion is covered with certain thickness transparent polymer material coating, thus forming the transparent protective sleeve of pulling cable 2 of all-transparent and subregion, this protective sleeve of pulling cable 2 disclosure satisfy that protective sleeve of pulling cable mechanical property and durability, protective sleeve of pulling cable 2 can completely cut off outside air, and protective sleeve of pulling cable 2 and steel wire interfascicular can slidings.Described macromolecular material is dimethyl siloxane macromolecule.
Embodiment 2
A kind of transparent drag-line manufacture method being easy to lasting hazard detection is as follows:
Step one: dimethyl siloxane macromolecular material and firming agent are mixed with mass ratio 10: 1, uses magnetic stirrer uniform stirring under certain rotating speed；Liquid after obtaining is put in vacuum drying oven, circulates evacuation and venting, remove the bubble in liquid；
Step 2: dimethyl siloxane macromolecule material solution obtained above is injected whole steel tendons or steel tendon surface, subregion, wherein partially transparent drag-line requires that the macromolecule material solution of transparent region is built with the pe sheath in nontransparent region simultaneously, then put it in baking oven and solidify, the transparent drag-line of the dimethyl siloxane macromolecular material coating finally obtained.
Cured formation meets the transparent dimethyl siloxane macromolecule material coating of protective sleeve of pulling cable mechanical property and durability, it is not only able to contacting of isolation steel tendon and outside air, and the transparent protective sleeve of pulling cable formed can observe directly the lasting hazard situation of steel tendon.
