Abstract
The invention relates to a sealing method in the technical field of bridges and construction engineering, in particular to a method for connecting and sealing hot-extrusion coating steel wire inhaul cables and cable clips. The method mainly comprises the following steps: (1) stripping hot-extrusion PE protective sleeves with corresponding length on mark points of the cable clips of a suspension cable by a hot melt method to make steel wires exposed outside; (2) filling elastic sealing glue on the periphery of the inner wall of great circle counter bores on two sides of each cable clip evenly; (3) arranging and fastening a left cable clip and a right cable clip through bolts; (4) arranging two rubber insertion strips at the left end and the right end of each cable clip respectively, pressing the rubber insertion strips into the counter bores, sealing gaps among the insertion strips by the sealing glue, and after finishing, filling silica gel from outside in turn for sealing; and (5) applying wetting corrosion-resistant sealing paste on seams of the periphery of the cable clips to make the cable clips sealed into a whole. The method solves the problems of watertightness and sealing of a cable body self when the hot-extrusion coating inhaul cables are connected through the cable clips, and can effectively prevent the corrosion of the steel wires in the cable clips because rain water or moisture enters the inside of the cable clips, and prolong the service life of the inhaul cables.
Description
Technical field
The present invention relates to the encapsulating method of a kind of bridge and construction engineering technical field, specifically is that a kind of hot-extrusion coating steel wire inhaul cables and cable is connected encapsulating method with cord clip.
Background technology
Along with the fast development of Chinese national economy, highway bridge and building trade are launched just throughout the country in large area as the infrastructure of urban construction.Nowadays day by day in different style, the various informative bridge and building structure, hot extrude bag PE sheath wire digging line is owing to its outstanding tensile property and long application life have obtained using widely.In some small bridge and building structure, extruding being connected to each other between the sheath wire digging line relies on cord clip to finish, but have a certain degree mutually between suspension cable and hoist cable make cord clip must provide enough clamping forces resist by hoist cable cause along the downslide component under the suspension cable tangential direction, this just requires to divest the PE sheath on the suspension cable, cord clip is clamped on Steel Wire Surface, but this process has caused Steel Wire Surface to be exposed in the air, be subjected to the influence of rainwater, moisture, can cause the steel wire corrosion for a long time, reduce drag-line application life.
Summary of the invention
The present invention seeks to ensureing under the prerequisite of hot extrude bag sheath drag-line by the reliable connection of cord clip, special internal hermetically-sealed construction by cord clip adds the barrier propterty that potted component and encapsulant improve the drag-line body, thereby strengthen the corrosion resistance of drag-line, thereby improve the application life of bed rearrangement bridge or building structure.
The present invention is achieved by the following technical solutions, and the inventive method mainly comprises the steps:
(1) sentences the hot extrusion PE protective jacket that hot fusion method divests respective length at the gauge point of suspension cable cord clip, make outside steel wire is exposed to;
(2) around the inboard hole wall of cord clip both sides great circle counterbore, evenly squeeze into elastic sealant;
(3) with bolt install fastening about two cord clips;
(4) respectively join two rubber filler rods and be pressed into counterbore at two ends, the cord clip left and right sides, equally with fluid sealant sealing, squeeze into silica gel sealing after finishing successively from the outside between filler rod;
(5) crevice place is smeared the non-drying corrosion inhibiting sealant around the cord clip, and it is as a whole that cord clip is sealed to.
In the described step (4), filler rod is of a size of Ф 10.
The principle of the invention: utilize PE cylindrical roundness and fineness characteristics preferably, in the PE of cord clip two ends and drag-line external diameter junction, the elastic sealant of annotating respectively from inside to outside, embed the multi-sealed measure of double-deck elastic caoutchouc wind-lace and silica gel, at last at two cord clips crevice place filling all around non-drying corrosion inhibiting sealant, make the cord clip inner wire and the external world isolate fully, thereby reach etch-proof purpose.
Compared with prior art, the present invention has following beneficial effect:
Solve between hot extrude bag sheath drag-line the waterproof sealing problem of cable body when connecting itself by cord clip.Tool of the present invention can prevent effectively that rainwater or moisture from entering cord clip inside, causes the corrosion of cord clip inner wire, prolongs drag-line application life.
Description of drawings
Fig. 1 is the sealed structural representation between drag-line and cord clip.
Fig. 2 is the transverse sectional view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated: present embodiment has provided detailed embodiment being to implement under the prerequisite with the technical solution of the present invention, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1 and Figure 2, the present embodiment encapsulating method is:
1. sentence the hot extrusion PE protective jacket 7 that hot fusion method divests respective length at the gauge point of suspension cable cord clip 5, make outside steel wire 6 is exposed to;
2. around the inboard hole wall of cord clip 5 both sides great circle counterbores, evenly squeeze into elastic sealant 1;
3. two cord clips 5 and with bolton about installing.
4. respectively join the rubber filler rod 2 of two Ф 10 and be pressed into counterbore at two ends, cord clip 5 left and right sides, 2 of filler rods seal with fluid sealant 1 equally, squeeze into silica gel 3 successively from the outside after finishing and seal.
5. crevice place is smeared non-drying corrosion inhibiting sealant 4 around the cord clip 5, and it is as a whole that cord clip 5 is sealed to, and the top also is provided with bucker 8.
The waterproof sealing problem of cable body itself when compared with prior art, present embodiment solves between hot extrude bag sheath drag-line and to connect by cord clip. Can prevent effectively that rainwater or moisture from entering cord clip inside, cause the corrosion of cord clip inner wire, prolong drag-line service life.
Claims (2)
1. a hot-extrusion coating steel wire inhaul cables and cable is connected encapsulating method with cord clip, it is characterized in that, comprises the steps:
(1) sentences the hot extrusion PE protective jacket that hot fusion method divests respective length at the gauge point of suspension cable cord clip, make outside steel wire is exposed to;
(2) around the inboard hole wall of cord clip both sides great circle counterbore, evenly squeeze into elastic sealant;
(3) with bolt install fastening about two cord clips;
(4) respectively join two rubber filler rods and be pressed into counterbore at two ends, the cord clip left and right sides, equally with fluid sealant sealing, squeeze into silica gel sealing after finishing successively from the outside between filler rod;
(5) crevice place is smeared the non-drying corrosion inhibiting sealant around the cord clip, and it is as a whole that cord clip is sealed to.
2. hot-extrusion coating steel wire inhaul cables and cable as claimed in claim 1 is connected encapsulating method with cord clip, it is characterized in that, filler rod is of a size of Ф 10 in the step (4).
