Abstract
The invention discloses a kind of methods that blow-off line is crossed in extra-high-tension cable process of deployment, which is characterized in that the first step prepares cable crossing blow-off line device；Second step covers cable crossing blow-off line device on blow-off line, while being firmly tied together cable crossing blow-off line device with blow-off line using rope；The end of cable to be laid is passed through the first metallic rod, the second metallic rod and third metallic rod, while guaranteeing that cable is located at the top of the first metallic rod, the lower section of the second metallic rod and third metallic rod by third step；The end of cable to be laid is fixed on mechanical traction device by the 4th step, and mechanical traction device moves towards to start to pull cable along groove.
Description
Technical field
The present invention relates to a kind of methods that blow-off line is crossed in extra-high-tension cable process of deployment.
Background technique
In the process of deployment of buried cable approximately as: firstly, establishment officer carry out topographic(al) reconnaissance, determine cable trench
Excavate route；Then groove excavates in establishment officer, finally carries out cable laying, and the common method of cable laying is that mechanical traction is applied
If.In order to guarantee the safety and cable construction quality of construction personnel, all first cable reel is steadily erected on pay off rack, frame
If cable disk, cable disk is rolled to the predetermined area by the arrow direction on drum, then steel shaft is through in drum axis hole,
The intensity and length of steel shaft should be combined with cable disk weight and width, enable drum activity freely, then led using machinery
Gravitation draws cable, and guidance cable moves forward, by cable laying into groove after, be finally exactly by groove soil-burial.
But it is frequently encountered blow-off line during excavating groove, cable to be laid is placed in groove in this way
Later using mechanical traction power draw cable if be easy for so that whole cable all vacantly.
Summary of the invention
The technical problem to be solved by the present invention is how to guarantee when mechanical traction power trailing cable encounters blow-off line whole
Root cable will not be suspended.
The above technical problem is solved in order to realize, the technical scheme adopted by the invention is that: a kind of extra-high-tension cable laying
The method of blow-off line is crossed in the process, which is characterized in that
The first step prepares cable crossing blow-off line device；
The cable crossing blow-off line device includes semicircle annulus, the first metallic rod, the second metallic rod, third gold
Belong to bar；
One end of first metallic rod connects the highest point of semicircle annulus, and one end of the second metallic rod connects semicircle
One minimum point of shape annulus, another minimum point of the semicircle annulus of one end connection of third metallic rod, and the first metallic rod,
Second metallic rod and third metallic rod are each perpendicular to the plane where semicircle annulus；
Second step covers cable crossing blow-off line device on blow-off line, while being arranged cable crossing using rope
Dirty plumbing installation is firmly tied together with blow-off line；
The end of cable to be laid is passed through the first metallic rod, the second metallic rod and third metallic rod, simultaneously by third step
Guarantee that cable is located at the top of the first metallic rod, the lower section of the second metallic rod and third metallic rod；
The end of cable to be laid is fixed on mechanical traction device by the 4th step, and mechanical traction device is along groove
Trend starts to pull cable.
Compared with the prior art, the advantages of the present invention are as follows: method disclosed by the invention can guarantee cable laying process
In not to be suspended under the action of mechanical traction power be that still cable can be made to move towards along groove under the action of tractive force
It is laid with.
Detailed description of the invention
Fig. 1 is the case where cable encounters blow-off line under the effect of mechanical traction power；
Fig. 2 is cable crossing blow-off line schematic device；
Fig. 3 is the effect diagram using cable laying after cable crossing blow-off line device.
Wherein, 1 is cable；2 be blow-off line；3 be the first metallic rod；4 be the second metallic rod；5 be third metallic rod.
Specific embodiment
Invention is described in further detail with reference to the accompanying drawing.
Embodiment: the method for blow-off line is crossed in extra-high-tension cable process of deployment, which is characterized in that
The first step prepares cable crossing blow-off line device；
The cable crossing blow-off line device includes semicircle annulus, the first metallic rod, the second metallic rod, third gold
Belong to bar；
One end of first metallic rod connects the highest point of semicircle annulus, and one end of the second metallic rod connects semicircle
One minimum point of shape annulus, another minimum point of the semicircle annulus of one end connection of third metallic rod, and the first metallic rod,
Second metallic rod and third metallic rod are each perpendicular to the plane where semicircle annulus；
Second step covers cable crossing blow-off line device on blow-off line, while being arranged cable crossing using rope
Dirty plumbing installation is firmly tied together with blow-off line；
The end of cable to be laid is passed through the first metallic rod, the second metallic rod and third metallic rod, simultaneously by third step
Guarantee that cable is located at the top of the first metallic rod, the lower section of the second metallic rod and third metallic rod；
The end of cable to be laid is fixed on mechanical traction device by the 4th step, and mechanical traction device is along groove
Trend starts to pull cable.
