Abstract
The utility model relates to a water proof case for stayed cable, which is characterized in that the device comprises a taper-type steel member (10), a HDPE pipe (11) and a seal ring (9), wherein the seal ring (9) is mounted in the outer slot; an external thread is positioned on the small end of the taper-type steel member (10) and an internal thread is positioned on one end of the HDPE pipe (11); the internal thread on the small end of the taper-type steel member (10) and the internal thread on one end of the HDPE pipe (11) work with each other. The utility model can prevent the rain water and the water vapor from getting into the cable; thereby, the device is of good water prevention effect and convenient use. The device can be widely applicable to cable-stayed bridges.
Description
Technical field
The utility model relates to the used steel strand stay cable of a kind of cable stayed bridge, relates in particular to a kind of cable-stayed bridge cable bucker.Belong to the road and bridge technical field.
Background technology
The used steel strand stay cable of cable stayed bridge is general all at HDPE pillar of cable body overcoat, between the pre-pipe laying bucker being installed on HDPE pillar and the beam, causes the corrosion of suspension cable cable body in the cable body to prevent that rainwater or aqueous vapor from entering.At present, Chang Yong steel strand stay cable waterproof is covered with two kinds of patterns: " Hough " formula bucker (referring to Fig. 1) and monolithic bucker (referring to Fig. 2)." Hough " formula bucker bends the steel plate of shaping for the two halves formula, after the suspension cable cable body installs, utilizes bolt to connect the HDPE pillar of holding with a firm grip it.This bucker because bolt corrosion and weather strip are aging, causes leakage easily in bridge operation process, cause rainwater or aqueous vapor to enter cable body.Monolithic bucker one end is enclosed within outside the pre-pipe laying, and the other end is inserted in the HDPE pillar, seals with thermal shrinkable sleeve in addition at the binding site of HDPE pillar and bucker.Because the contraction of thermal shrinkable sleeve can not guarantee itself and the sealing fully of HDPE pipe and pre-pipe laying fully, with and can produce aging phenomenon during use, so in bridge operation process, this structure is also leaked easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can guarantee fully that rainwater or aqueous vapor can not enter the suspension cable bucker in the cable body.
The purpose of this utility model is achieved in that a kind of suspension cable bucker, comprising: tapered steel member, HDPE pipe fitting and sealing ring,
Described sealing ring is embedded in the big end slot mouth of tapered steel member,
The small end of described tapered steel member is provided with external screw thread,
One end of described HDPE pipe fitting is provided with internal thread,
The internal thread of described tapered steel member small end cooperatively interacts with the internal thread of HDPE pipe fitting one end and is connected.
During installation, the other end of HDPE pipe fitting and the sweat soldering of HDPE pillar are integral, and the big end of tapered steel member is enclosed within on the pre-pipe laying.
Owing to adopt said structure, the HDPE pipe fitting closely is connected with the small end screw thread of tapered steel member, the HDPE pipe fitting is positioned at outside the tapered steel member, the sealing ring and the pre-buried seal of tube of the big end of while tapered steel member, guarantee big end of tapered steel member and the sealing of pipe laying in advance, rainwater and aqueous vapor can not be entered in the cable body, good water-proof effect, and easy to use.
Description of drawings
Fig. 1 is the work schematic diagram of " Hough " formula suspension cable bucker in the past.
Fig. 2 is the work schematic diagram of " integral body " formula suspension cable bucker in the past.
Fig. 3 is the work schematic diagram of the utility model suspension cable bucker.
Among the figure: bucker 1, fastening bolt 2, weather strip 3, HDPE pillar 4, pre-pipe laying 5, weather strip 6, suspension cable cable body 7, thermal shrinkable sleeve 8, sealing ring 9, tapered steel member 10, HDPE pipe fitting 11.
The specific embodiment
As shown in Figure 3, the utility model suspension cable bucker is made of tapered steel member 10, HDPE pipe fitting 11 and sealing ring 9.Described sealing ring 9 is embedded in the big end slot mouth of tapered steel member 10, and be installed on the pre-pipe laying 5 with tapered steel member 10, the small end of tapered steel member 10 is shaped on external screw thread, one end of HDPE pipe fitting 11 is shaped on internal thread, the small end external screw thread of tapered steel member 10 cooperatively interacts with an end internal thread of HDPE pipe fitting 11 and is connected, and the other end of HDPE pipe fitting 11 and 4 sweat solderings of HDPE pillar are integral.
Before suspension cable is installed, HDPE pipe fitting 11 and 4 sweat solderings of HDPE pillar are integral, tapered steel member 10 is screwed on HDPE pipe fitting 11, sealing ring 9 is embedded in the big end slot mouth of tapered steel member 1.Suspension cable cable body 7 passes the cavity in the above-mentioned syndeton.Suspension cable cable body 7 is installed in above-mentioned syndeton on the pre-pipe laying 5 after installing and finishing together, seals by sealing ring 9 between tapered steel member 10 big ends and the pre-pipe laying 5.
