Description
Technical field
The cable duct framework laid on a kind of power transmission sequence is the utility model is related to, the particularly a kind of type of power transmission sequence one dress
With formula cable duct.
Background technology
Chinese patent 200810162805.0 provides a kind of transforming plant assembly type cable slot body and method for paving, with transverse direction
Overall U-typed cross-section structure, segmentation prefabricating, field splicing is reproduced, and be substantially all prefabricated at the scene, it is not necessary to considered remote
Transport, assembling process.This prefabricated, fabricated cable slot body can greatly reduce construction work amount, shorten construction period,
Efficiency of construction and construction quality are improved, reduces construction cost.But this assembled of transformer station is applied to power transmission sequence work
Cheng Shang, then can there are the following problems：
1st, cable duct section is little, and the raceway groove total length in a transformer station is few, and can provide wider construction site,
Therefore it is more using in-situ precast, the method for on-site consolidation, it is not necessary to prefabrication and long-distance transportation；And in KV Electric Transmissions
In, because circuit mileage is grown, and corridor limit value, so scene does not possess the site condition of prefabricated ditch section, the patented technology side
Case can not be applied directly.
2nd, the body of power transformation station cable ditch employs water-proof concrete, although using spigot-and-socket tongue and groove between longitudinal channel
The mode of connection, seam crossing water-proof function is less demanding, but is substantially all in transformer station and disclosure satisfy that engine request.But
For KV Electric Transmissions, the environmental condition on raceway groove periphery is complicated, mostly the shallower city city of level of ground water, waterproof requirement
Height, then original interface mode is no longer applicable.
3rd, due to far from each other using the environment in transformer station and the environment in power transmission sequence corridor, power transformation station cable ditch
The cable duct that method for paving can not also be applied to power transmission sequence be mated formation engineering.
At present, the cable slot body of power transmission sequence is built by the way of scene is built by laying bricks or stones, takes, be laborious, it is difficult to meeting
Current engineering construction requirement.
The content of the invention
The purpose of this utility model be according in place of the deficiencies in the prior art and construction work can be reduced by providing one kind
Amount, shorten the construction period, reduce the type assembly type cable slot of power transmission sequence one of construction cost.
The purpose of this utility model is realized by following approach：
The type assembly type cable slot of power transmission sequence one, its structural feature be, the cable duct by plural number section ditch body head and the tail according to
Sequence connection composition, often save ditch body and include three prefabricated components：Two pieces of side wall members and one piece of base plate member, each prefabricated components
Be in " one " letter stencil type, base plate member in the both sides of length direction along being above provided with welding built-in fitting, and two pieces of side wall members
It is also equipped with welding built-in fitting on lower side edge, two pieces of side wall members are separately mounted to two surveys of the base plate member in length direction
It is welded to connect along upper, and by respective welding built-in fitting, after welding, two pieces of side wall members and the U-shaped structure of base plate member
Make；
The front end face for often saving ditch body is provided with tenon, and rear end face is then mortise, tenon and the previous fourth of the twelve Earthly Branches for saving ditch body rear end face
Eye joggle, and the mortise then tenon joggle with later section ditch body front end face, form end to end construction, in the gap at joggle
It is pressed with hydro-expansive rubber bar.
In engineering, prefabricated components are transported to job site from processing factory, then successively pacified bottom plate, side wall member etc.
Put to raceway groove, first carry out longitudinally connected, then side wall member is welded with the welding built-in fitting reserved on base plate member
Connection, finally bankets, installs the later works such as cable and annex.The utility model is by prefabricated two side walls for often saving cable duct
Laterally three sides are carried out with a bottom plate to decompose, and form the standard end face of three " one " types, ditch body component is changed by three-dimensional objects
Into two-dimensional products, the weight of single prefabricated components is not only reduced, also substantially reduces prefabricated components in processing, transport, storage
Volume Deng during, so, the efficiency of long-distance transport can be improved, solve the long-range fortune from processing factory to transmission line of electricity
Defeated problem, improve the scope that assembly type cable slot is applied in KV Electric Transmissions.Further, from horizontal, side wall structure
Part and flooring element can meet the force request that bending moment is maximum between side wall and bottom plate using being welded to connect；From longitudinal direction, often save
Water-proofing treatment is carried out by the way of tenon shape interface and hydro-expansive rubber bar combine between cable duct, is not only able to meet structure
Waterproof requirement, but also substantially reduce the workload of Site Welding.
The utility model can be specially further：
The side wall member and base plate member for often saving ditch body are carried out with forward and backward section ditch body junction using a plurality of single ended bolts
Connection.
Because KV Electric Transmissions mesorelief is complicated, the waterproof problem of cable duct is the medical record of the most important thing, in order to
Waterproof effect is further improved, further fixed connect directly is done using single ended bolt in the longitudinal member of side wall and base plate member
Connect, with reference to tenon shape interface and hydro-expansive rubber bar before, substantially increase waterproof effect.
The medial surface for often saving both sides wall member in ditch body is embedded with groove profile cable bearer built-in fitting.
The groove profile cable bearer built-in fitting is to be used to install groove profile cable bearer, when this built-in fitting is prefabricated in the factory just
Prefabricated processing is together carried out, not only efficiency high, and " zero welding " process of horizontal lateral frame installation can be realized, greatly reduced
Cable bearer field erected quantities, improves operating efficiency.
In summary, the utility model provides a kind of type assembly type cable slot of power transmission sequence one, by prefabricated often economize on electricity
Two side walls of cable ditch and a bottom plate carry out laterally three sides and decomposed, and the standard end face of three " one " types are formed, by ditch body component
Two-dimensional products are converted into by three-dimensional objects, not only reduce the weight of single prefabricated components, prefabricated components is also substantially reduced and exists
Volume during processing, transport, storage etc., so, construction work amount can be reduced, shorten the construction period, improve long-range fortune
Defeated efficiency, construction cost is reduced, improves the scope that assembly type cable slot is applied in KV Electric Transmissions.
