Abstract
The utility model relates to a full sealed dragline which is used for cable stayed bridge or suspension bridge or other cable bearing unique structure, comprising a steel tendon 3 and the protection coat 4, 5, and 6 coated on the outer surface of the steel tendon 3. The full sealed dragline is characterized in that: the outer surface of the single steel wire 1 of the steel tendon 3 and the interstice between every two single steel wires 1 are respectively coated with an anticorrosive sealing layer 2. Therefore, even the single steel wires have disturbance when the steel tendon is pressed, and the original zinc protecting layer of the steel wire can not be damaged. In the anchor manufacturing process, the moisture can not enters into the inner side of the steel wire of the dragline easily, and the head of the dragline can also not have corrosion and breakage. Therefore, the utility model has good sealing performance and long service life.
Description
Technical field:
The utility model relates to a kind of construction cable-stayed bridge or suspension bridge or other Suo Cheng unique construction full seal type drag-line.
Background technology:
Wire digging line is the main bearing member of cable-stayed bridge.Owing to expose in atmosphere throughout the year, expose to the sun and rain, corrosion and destruction easily takes place.For addressing this problem, in recent years, people have proposed to squeeze the technical scheme of attached plastics at the good steel tendon outer surface of twisting, and are used.It is to improving protection effect, prolonging drag-line and played certain effect service life.But because stay cable end needs the strip off overcoat when making anchor head; therefore stay cable end anchor head place becomes a water inlet hidden danger; and owing between the individual wire of the stressed back of steel tendon changing of the relative positions friction takes place easily; the protection zinc layer of steel wire is destroyed easily; therefore its antiseptic property is relatively poor; corrosion and destruction easily takes place in the drag-line cable body, has reduced drag-line service life.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of good airproof performance is provided, and drag-line is difficult for taking place the full seal type drag-line of corrosion.
The purpose of this utility model is achieved in that a kind of full seal type drag-line, the overcoat that comprises steel tendon and be coated on the steel tendon outer surface is characterized in that the individual wire outer surface of steel tendon and the gap between individual wire and the individual wire are coated with the preserving and sealing layer.Like this, even between the individual wire of the stressed back of steel tendon the changing of the relative positions takes place, the former protection zinc layer of steel wire can be not destroyed yet; In system anchor process, moisture content is difficult for entering the steel wire inside of drag-line cable body, and the rope head position of drag-line corrosion and destruction can not take place yet.Therefore the utility model sealing spy is good, long service life.
Description of drawings:
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model.
The specific embodiment:
As Fig. 1, the utility model is a kind of full seal type drag-line.Form by central steel tow 3 and the black high density polyethylene (HDPE) middle level 5 and the color high-density polyethylene outer 6 that are coated on the high-strength polyester fiber band protection internal layer 4 of central steel tow 3 outer surfaces and are coated in fiber band 4 outer surfaces.Central steel tow 3 is twisted together by individual wire 1.Characteristics of the present utility model are that the individual wire 2 of central steel tow 3 is after zinc-plated, in preserving and sealing type organic compound coatings 2 such as twisting process outer surface anticorrosion with painting closed type grease or paraffin waxes.Like this, be coated with preserving and sealing type organic compound coating 2 in the outer surface and the gap between individual wire 1 and the individual wire 1 of individual wire 1.
Claims (4)
1, a kind of full seal type drag-line, the overcoat (4,5,6) that comprises steel tendon (3) and be coated on steel tendon (3) outer surface is characterized in that individual wire (1) outer surface of steel tendon (3) and the gap between individual wire (1) and the individual wire (1) are coated with preserving and sealing layer (2).
2, a kind of full seal type drag-line according to claim 1 is characterized in that preserving and sealing layer (2) adopts preserving and sealing type grease or paraffin wax.
3, a kind of full seal type drag-line according to claim 1 and 2 is characterized in that overcoat (4,5,6) comprises protection internal layer (4), middle level (5) and outer (6), and internal layer (4) adopts high-strength polyester fiber band.
