Description

Exempt to lift new construction method based on tunnel cable
Technical field
The present invention relates to a kind of power cable layer construction methods of installation, and in particular to one kind is exempted from lift based on tunnel cable and applied Work new method belongs to tunnel inner cable installation Technology field.
Background technique
Cable tunnel is the tunnel for being used to be laid with cable, for that can accommodate walking for the cable being largely laid on cable bearer Corridor or tunnel type structures.In power demand today's society growing day by day, especially in city, relative to other laying sides The advantage of formula, cable tunnel is apparent: 1. cable tunnel is disposable investment construction, is equipped with many cable branch in tunnel Frame, after tunnel is built up, it is only necessary to check on time, without proposing new plan to relevant departments, facilitate maintenance, maintenance or more Change cable;2. cable tunnel can be reliably prevented external force destruction, the influence of external condition is reduced, construction is facilitated;3. can accommodate big Cable is measured, and is not influenced vulnerable to external force, cable life is in a disguised form improved.In short, the application of cable tunnel can not for urban development Or lack, the construction technology laid in cable tunnel should also grow with each passing hour.
Technical difficult points are laid in cable tunnel at present to be: 1) cable that laying is completed being promoted to cable bearer, This process still relies primarily on manually at present, and since cable self weight is larger, lifting process need to consume a large amount of manpowers, low efficiency Under;Secondly, space is limited in cable tunnel, cable bearer is metallic facility again, easily causes personnel and cable in work progress Damage.
2) in practice of construction when meeting with tunnel turning, traditional construction technique solution is special in turning setting Personnel pass through bend by dragger tractive force bending cable using crowbar support cable.There are many for conventional construction method Drawback: increasing unnecessary human cost, and speed of application is slow, be easy to cause the damage of personnel and cable.
3) traditional work uses diesel oil motor-driven grinding mill, since space is limited in cable tunnel, unsmooth, conventional diesel engine of divulging information Dynamic the disadvantages of to be twisted that there are noises big, harmful gas emission is big, volume is large-scale handicapped.
Summary of the invention
The technical problems to be solved by the present invention are: overcoming the deficiencies in the prior art, provide a kind of based on tunnel Cable exempts to lift new construction method, so that construction light and fast of the cable at tunnel turning, and it is not necessarily to manpower, improve construction effect Rate reduces construction cost, while reducing the cable fault in work progress.
The present invention is adopted the technical scheme that in order to solve the technical problem: one kind exempting from the new side of lift construction based on tunnel cable Method includes the following steps:
Preparation includes:
1) the outer ground of tunnel shaft is cleared up, is smooth;
2) fence is arranged at tunnel well head;
3) it is disposed available manpower according to work on the spot process and tool equipment.
Operating procedure:
1) well external equipment in cable tunnel is arranged: fixation position of the cable reel stent outside well on ground is determined, in cable reel stent Unpowered V-type cable drum bracket, and fixed V-type cable drum are set up between tunnel well head, hanging turn of installation at tunnel well head To pulley.
2) cable is into well: cable reel is placed on the cable reel stent, by cable uncoiling on the V-type cable drum, And it will be in cable uncoiling to tunnel shaft across the hanging angle pulley.
3) equipment is arranged in cable tunnel: tunnel entrance installs the aerial quarter block of cable, installs electronic lead in tunnel Draw and be twisted, every five meter ampere fills the tunnel cable straight line unfolding Special-purpose bench coaster on tunnel wall mounting, and passes through cunning The long handle bolt of vehicle bottom is fixed as one with tunnel cable bracket;Tunnel turning, by the big of angle of turn and cable size The aerial quarter block of cable, and the adjustable pine of traction device of the aerial quarter block upper end of the cable are installed in small selection Tightly.
4) hauling rope is arranged: the one ends wound of hauling rope being rolled in the mill that the electric traction is twisted, passes through the tunnel Road cable straight line unfolds Special-purpose bench coaster and the aerial quarter block of the cable, other end connecting cable;The hauling rope exhibition It puts when being twisted upper to the cable electric traction, the hauling rope rolls on winding not less than 3 in the mill that the electric traction is twisted Circle, has stayed hauling rope tail rope by special messenger.
5) cable pulling: on inspection equipment install and connect it is errorless after, traction instruction is assigned by operating personnel, described in starting Electric traction is twisted trailing cable, and end sends special messenger's follow-observation cable by coaster situation during cable pulling, when logical When crossing at turning of cable, reducing hauling speed ensures that cable passes through the aerial quarter block of the cable, until cable is whole Traction stops afterwards in place.
6) it checks cable position: checking whether the cable position on cable position and corner cable trough on cable trough arrives Position, when cable is not to the correct position on cable trough, adjustment cable until cable in place.
7) equipment Removal: cable pulling in place after, remove the hauling rope, remove the electric traction and be twisted, remove institute State tunnel cable straight line unfolding Special-purpose bench coaster and the aerial quarter block of the cable.
The method for dismounting of the tunnel cable straight line unfolding Special-purpose bench coaster are as follows: special in tunnel cable straight line unfolding With electronic top cable device is used below half meter or so before and after rack coaster of cable, cable is held up slightly, unclamps pulley and tunnel Long handle bolt between road cable bearer, takes out cable coaster from bracket, and electronic top cable device is dropped down on tunnel cable bracket ?.
The method for dismounting of the aerial quarter block of cable are as follows: loosen the aerial quarter block take-up of the cable, electricity Cable stress is eased, and is twisted cooperation with the electric traction, and cable is placed the tunnel cable bracket at turning by artificial control On suitable position.
After equipment is all removed, cable snake shaped laying is carried out according to design requirement, job step is fixedly mounted.
8) it checks cable laying quality: checking the quality after the completion of cable laying, terminate operation after passed examination.
The beneficial effects of the present invention are: the present invention is lifted this working procedure without cable, cable can be directly on bracket Laying reduces difficulty of construction, reduces personnel needed for constructing, equipment volume is light, simple and quick;It also can avoid applying simultaneously It is contacted between cable and bracket during work, reduces the probability of cable fault.
