Description
Technical field
The cable duct framework laid on a kind of power transmission sequence is the utility model is related to, particularly a kind of power transmission sequence matrix 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, in transformer station, cable duct section is little, and the raceway groove total length in a transformer station is few, and can provide wider
Construction site, therefore more using in-situ precast, the method for on-site consolidation, it is not necessary to prefabrication and long-distance transportation；And sending
In electric line engineering, because circuit mileage is grown, and corridor limit value, so scene does not possess the site condition of prefabricated ditch section, and it is described
Art solutions 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Height, then original interface mode is no longer applicable.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 power transmission sequence matrix assembly type cable slot of construction cost.
The purpose of this utility model is realized by following approach：
Power transmission sequence matrix assembly type cable slot, its structural feature be, the cable duct by plural number section ditch body head and the tail according to
Sequence connection composition, the cross section for often saving ditch body constructs in matrix, including bottom plate and biside plate；The medial surface of biside plate is embedded with more
Individual groove profile cable bearer built-in fitting, the groove profile cable bearer built-in fitting is perpendicular to backplane；The front end face for often saving ditch body is set
Be equipped with tenon, rear end face is then mortise, the mortise joggle of tenon and previous section ditch body rear end face, and mortise then with later section ditch body
The tenon joggle of front end face, forms end to end construction, and hydro-expansive rubber bar is pressed with the gap at joggle；Often save ditch
Body is fixedly connected with forward and backward section ditch body junction in joggle using a plurality of single ended bolts.
The ditch body of merogenesis concave configuration described in the utility model can be prefabricated in factory, meanwhile, groove profile cable bearer is pre-
Embedded part while ditch body is prefabricated also in advance on the biside plate of ditch body, can be by prefabricated components from processing in construction work
Factory transports to job site and installed, and employs and solves the problems, such as on power transmission sequence without prefabricated site condition, on the other hand,
Propose that longitudinal direction is connected by screw bolts, tenon type interface adds the connected mode of hydro-expansive rubber sealing, solve power transmission well
The problem of line environment complexity, meet the waterproof demand of raceway groove.Thus the utility model is prefabricated, live by ditch body member segments
Assembling, the weight of single prefabricated components is not only reduced, also substantially reduce prefabricated components in processes such as processing, transport, storages
In volume, so, the efficiency of long-distance transport can be improved, solve the long-distance transport from processing factory to transmission line of electricity and ask
Topic, expands the scope that assembly type cable slot is applied in KV Electric Transmissions.Moreover, connect between often saving cable duct using tenon shape
The mode that mouth and hydro-expansive rubber bar combine carries out water-proofing treatment, is not only able to meet structurally waterproof requirement, but also significantly
Reduce the workload of Site Welding.The groove profile cable bearer built-in fitting is to be used to install groove profile cable bearer, and this is pre-buried
Just prefabricated processing is together carried out when part is prefabricated in the factory, it is not only easy to operate, and " the zero of horizontal lateral frame installation can be realized
Welding " process, substantially reduces the field erected quantities of cable bearer, improves operating efficiency.
The utility model can be specially further：
The weight for often saving ditch body is less than 20 tons, and multiple lifting suspension hooks are distributed with biside plate upper end edge.
Produced for power transmission sequence prefabricated member and separate, transport and lift the features such as condition is limited with fabricating yard, carried
The measures such as suspension hook lifting, control single-unit prefabricated components weight are gone out, so as to which further the transport for component and assembling provide basis
Condition.According to the data of experimental project, matrix assembly type cable slot is obvious compared with the lifting of cast-type cable duct duration, and an operation follows
Duration in ring can be foreshortened to about 10 days by 40 days, there is obvious efficiency to improve, cost reduces and preferable economy.
It is 3.0 ~ 6.0m often to save ditch body length.
The size of ditch body is controlled from size, in order to the transport and lifting of prefabricated components, according to the scene of power transmission sequence
Condition, it can be constructed using small-size hoisting machine tool.
At least two bolt hole is often distributed with the bottom plate and biside plate of section ditch body respectively, is distributed in every section ditch body
On front and rear end.
The bolt hole is to be used to single ended bolt connection use, and the connection of single ended bolt is uniformly distributed in bottom plate and biside plate
On, achieved a fixed connection and waterproof homework so as to comprehensive.
In summary, the utility model provides a kind of power transmission sequence matrix assembly type cable slot, using ditch body component point
The prefabricated, Assembling of section, not only reduces the weight of single prefabricated components, also substantially reduce prefabricated components processing, transport,
Volume during storage etc., it is proposed that longitudinal direction is connected by screw bolts, tenon type interface adds the connection side of hydro-expansive rubber sealing
Formula, solve the problems, such as power transmission sequence environment complexity well, meet the waterproof demand of raceway groove.So, construction can be reduced
Quantities, shorten the construction period, improve the efficiency of long-distance transport, reduce construction cost, expand assembly type cable slot in power transmission
The scope applied in line project.
