Composite coating layer on fine layer of cloth.
By using above-mentioned technical proposal, glass-fiber-fabric self-strength is high, plays the effect on basis；Stuck out one's tongue on glass-fiber-fabric multiple
Close dope layer and then play a part of waterproof.
Further set：The bucker profile is set to round table-like, sets anti-between sheath at the small end of round platform
Water-stop block.
By using above-mentioned technical proposal, water-proof sealing block can improve sealing, in general, round table-like bucker
Small end be set to deviate from ground side, water-proof sealing block is filled out and is located at small end, the environmental liquids such as rainwater can be effectively reduced
The possibility of infiltration.
Further set：The water-proof sealing block is likewise provided as round table-like, and it is big end close to bucker one end, and anti-
Water-stop block is set to be hollow, and its inwall is affixed on sheath.
By using above-mentioned technical proposal, when the liquid such as extraneous rain are fallen, rainwater inclines along water-proof sealing block
Inclined-plane is fallen, compared to columned water-proof sealing block, and this bevelled structure of band is more conducive to draining.
Further set：The sealing block is set to polyurethane water-proof paint block.
By using above-mentioned technical proposal, it is same that polyurethane rate of drying block, adhesive force are strong, physical and mechanical properties is excellent
When, also water-fast, moisture resistance, salt tolerant characteristic, additionally it is possible to band wet trade improves operating efficiency.
Further set：The bucker is set to two separate branch's covers.
By using above-mentioned technical proposal, first one of branch cover can be fixed at drag-line, so subsequently applied
During work, the effect of benchmark is served, beneficial to integrally-built complete, steadiness.
Further set：Inwall, which is sticked, at the small end of round table-like branch's cover rubber strip.
By using above-mentioned technical proposal, rubber strip is flexible, and branch's cover with rubber strip is arranged at drag-line
When, after rubber strip is squeezed, during elastic deformation resets, the gap between drag-line and branch's cover is filled up, sealing is played
Effect.
Further set：The sheath is set to be attached at the sheet metal on drag-line.
By using above-mentioned technical proposal, sheet metal surface is smooth, is sticked behind drag-line surface, thick compared to drag-line surface
Rough lines, current are more easy to, from smooth sheet metal surface landing, reduce the corrosion that current adhesion is caused.
