Description
Technical field
The present invention relates to a kind of piping lane construction method, specifically, is to be related to a kind of piping lane cable laying method.
Background technology
With continuous application of the piping lane technology in city underground engineering, the innovation of the construction in management is always us and chases after
The standard that seeks to achieve breakthrough, laying for cable is exactly a very important construction technology, and traditional cable laying is one while needing
Want the work of a large amount of manpowers.Number of workers increase causes the tissue of human resources, personal safety management difficulty to rise therewith, and manages
Cable laying in corridor is even more that one loaded down with trivial details and the construction technology of complexity, takes, effort is to the holistic cost of engineering and from the duration
Arrive key effect.
Content of the invention
For above-mentioned deficiency of the prior art, the present invention provides a kind of raising operating efficiency, reduces management difficulty, reduction
The piping lane cable laying method of construction cost.
The technical solution used in the present invention is：

Specific embodiment
Referring to the drawings and embodiment the present invention will be described in detail：
Accompanying drawing 1 understands that a kind of piping lane cable laying method comprises the steps：
Cable 1 is transported to scene, carries out cable bearer 2, and by cable 1 on cable bearer 2, cable bearer is placed on temporarily
Or permanent construction hole 3；
The main supporting steel pipe of the cable hank weight that sets up as needed need to select larger pachydermia Guan Weiyi, two pieces of slip iron block thickness benefits
Slightly larger, cable hank weight can be born by the short distance of cable bearer and be defined；
The maximum cable disk size of cabling, determines the height of cable bearer as needed；
The height on cable bearer highest pitch-row ground should be greater than cable hank radius 100mm or so, it is ensured that cable hank get up after energy
Positive rotational is defined.
Cable bearer highly determine after with Pythagorean theorem calculate other supports at the length of material carry out blanking.
All into triangular form in cable bearer all directions after shaping, triangular form physically has stability characteristic (quality).
Rack winch 10 is installed, model is determined according to the actual requirement at scene；
Fixed angle pulley 4 is installed in permanent construction hole end；
Fixed angle pulley 4 is fixed on fixing rotary on pulley bracket 5；
Fixing rotary is attached with main body built-in fitting to pulley bracket 5 by bolt；
Fixed angle pulley mode with bolts, easy to disassemble and recycling, angle pulley is according to live angle, electricity
The position height that cable lays, is determined, and is made using 100 square steel；It is welded on 20mm steel plates；
It is required that the pre-buried quality of main body is qualified, most positioning requirements are higher.
Cable linear transport pulley 6 is installed；
Cable linear transport pulley should be firm when fixing,
Cable linear transport pulley should be leaned against from walking on stage recently on one side when fixed, be easy to bundle；It is not to tie up in the middle of crane span structure 7；
Tie up, after being easy to discharge a cable on side, cable is removed pulley, second can be laid, the 3rd ... near walking on stage
Where people operates well cable to have again and can put.
In bottom one layer of Multilayer bridge frame 7, to lay high-tension cable be extremely difficult, is bound with rope using manually laying
Draw, does not draw several meters rope must be passed through once and the bad power of making is cumbersome from crane span structure support.Using telpher
Lay crane span structure width and interfloor distance is difficult to put down cable transfer face that this is a difficult problem.
Power suffered by the pulley of turning is maximum, and quarter block must be fixed very firm, once otherwise quarter block quilt
Personnel are turned in drawing and cable will all be on the hazard.
When turning pulley is fixed, emphasis is fixed turning of cable and is formed on the exterior angle of angle.Fixing point position is as more as possible, with
Reach the target that safety in production is for first.
Steel wire rope 8 is caused 1 starting point of cable, is connected with cable by the special drawing head of cable；
Need to use the snakelike set of cabling specific purpose tool in the case where cable head does not have special drawing head, snakelike set is net
The bigger parcel cable of shape structure pulling force is tighter, is just difficult to skid.
Snakeskin set of connection devices, steel wire rope are provided with steering ring with the junction of cable.
But in order to solid and reliable preferably snakelike set afterbody iron wire colligation again.In order to mode cable knots and interior
Strength, adds free steering ring in snakelike set front end, cracks interior strength, prevents cable from knotting.
Start equipment and start trial operation, terminal and joint want someone to be guarded, speed is unsuitable too fast, after having no problem
Start cabling, laying speed equally can not be too fast, while each position of main detection, prevent cable fault or
Mechanical wounding.
The rack winch carries out pre-buried, hoist engine employing in main body construction in advance using original pre-buried form
Bolt is connected with built-in fitting.
Ladder-type bridge frame, cable linear transport pulley are fixed on above two steps of crane span structure.
After straightway pulley rotation, less, bridge ladder extremely can sustain the strength to stress completely.
Plate channel type crane span structure, cable linear transport pulley are bolted on the steel construction cross-arm support of lower section.
Whole pipeline is long, sets up cable in middle appropriate location and twists grinding machine less important work.
At the discrepancy in elevation, will not advance with the gradient camber of crane span structure after cable stress, but can be between two sustainable points
Form the very big line-like of radian.
When cable testing bridge not in the superiors when, where the discrepancy in elevation cable will wipe upper strata traveling, be not acted upon inherently
Cable is scratched, upper strata may be lifted upwards when upper strata is insecure.
Pulley upside down be fixed on upper strata very firm where, hang upside down the straight line formed between point and other pulley support points
On should there is no other obstacles.
Piping lane cable laying method of the present invention, Traditional Man transport cable labor intensive are excessive, and adopt electric cable transporting machine
Though can solve the problem that human problems, generation expense is more, and the cable length that electric cable transporting machine drives is limited, it may be necessary to multiple stage
Equipment, such machine cost input are excessive, and traction power is larger in this respect, can coordinate pipeline other operations, such as after installation
Pipeline construction etc., disposable input, input cost be not high, recycles, and greatlys save human and material resources, shortens the construction period, drop
Low construction cost.
The above, is only presently preferred embodiments of the present invention, not the structure of the present invention is made any pro forma
Limit.Any simple modification, equivalent variations and modification that every technical spirit according to the present invention is made to above example,
Belong in the range of technical scheme.
