It is improved in sealing structure and tamper-proof aspect.2, the filled polyurethane expanded material in built-in pipe（See《A kind of new oblique pull
Bridge end built-in pipe fills anti-corrosion method》）, at present the polyurathamc overwhelming majority on the market be all not achieved sealing block water
Effect, but the effect for water of attracting deposits are that the corrosion of dragline anchorage creates condition in this way, in addition the filled polyurethane in built-in pipe
Expanded material is unfavorable for the inspection in later stage and the replacement of drag-line.3, pressure bladder or close using unvulcanised is added under embedded pipe orifice
Sealing.The patent of pressure bladder is shown in 102953334 A of CN《Tube expansion sealing type guy cable and its application method》, this method it is close
Envelope effect is mainly determined by installation personnel, if has good sealing effect currently without operable method.For
Unvulcanised fluid sealant is mainly bonding with the HDPE of drag-line bad, and disengaging is easy tod produce under the vibration of drag-line and can not be hindered
Water.
Invention content
The purpose of this utility model is to provide a kind of sealing structure of drag-line embedded pipe orifice, this kind of drag-line embedded pipe orifice

There is preferable cementability, elasticity and intensity with steel so that drag-line has reliable anti-corrosion effect in vibration processes；It is real
The hermetically sealed performance of existing drag-line embedded pipe orifice.
The technical solution to solve the above problems is：A kind of sealing structure of drag-line embedded pipe orifice, including to be mounted on drag-line pre-
The waterproof of pipe laying mouth, it is characterised in that：Also have by 1 layer or 2 layers between waterproof inhaul cable body and waterproof
The sealing structure layer that sealing material layer is constituted.
Its further technical solution is：Have between waterproof inhaul cable body and waterproof by 2 layers of sealing material
The sealing structure layer that layer is constituted, be close to drag-line cable body is viscoplasticity sealant layer, and thickness is 1~100mm, is sealed in viscoplasticity
There is the silicone structure glue-line being made of the structural silicone adhesive filled in gap between the outside and waterproof of glue-line.
Its further technical solution or：Have between waterproof inhaul cable body and waterproof by 1 layer of sealing material
The sealing structure layer that the bed of material is constituted, this layer of sealing material is the structural silicone adhesive by being filled between drag-line cable body and waterproof
The sealant layer that the silicone structure glue-line or viscoplasticity fluid sealant of composition are constituted.
The viscoplasticity fluid sealant includes polyolefin viscoplasticity fluid sealant or polybutene viscoplasticity fluid sealant.
Due to taking above structure, compared with prior art, a kind of sealing knot of drag-line embedded pipe orifice of the utility model
Structure has the characteristics that and advantageous effect：
1, a kind of sealing structure of drag-line embedded pipe orifice of the utility model has double sealing structure, has reliable close
Seal effect and better anti-corrosion effect：
A kind of sealing structure of drag-line embedded pipe orifice of the utility model includes the waterproof shield mounted on drag-line embedded pipe orifice
Cover and the sealing structure in waterproof, the sealing structure in the waterproof be waterproof inhaul cable body with it is anti-
There is the sealing structure layer being made of 1 layer or 2 layers of sealing material layer between water shield；To form dual-seal, therefore have
Reliable sealing effect, anti-corrosion effect are more preferable.
2, a kind of sealing structure of drag-line embedded pipe orifice of the utility model is that combination is constituted, simple in structure, dismounting side
Just, there is positive effect to the maintenance of later stage drag-line and replacement.
With reference to the accompanying drawings and examples to a kind of technology of the sealing structure of drag-line embedded pipe orifice of the utility model spy
Sign is described further.
