Description
Technical field
The present invention relates to power domain construction, especially a kind of cable duct bank and its construction method.
Background technology
With the growth requirement of Urbanization Construction, power cable gradually switchs to underground laying by setting up in the air.
The form that cable duct bank is generally used when traditional cable laying, especially a plurality of cable laying, is opened by scene
Foundation trench is dug, cable pipe special, then casting concrete maintenance molding are laid.There are operation sides for this traditional approach greatly, applies
The shortcomings of work period is long, scene is seriously polluted, especially during municipal cable duct bank is laid, can cause urban road to seal
Stifled, poured in place concrete pollutes environment, seriously affects daily life, does not meet the demand of Modern Urban Development.
Invention content
The problem of based on the above existing traditional construction technology, a kind of cable duct bank of present invention offer and its construction party
Method can realize factorial praluction, assembling assembly and mechanized construction.
The technical solution adopted by the present invention is as follows：
A kind of cable duct bank, including tube body, cable pipeline and connector U-shaped card pillow, cable pipeline runs through tubular body, described
The end face of tube body is equipped with the overlap joint faulting of slab ends of protrusion；The overlap joint faulting of slab ends is placed in connector U-shaped card pillow.
Further, the cable duct bank further includes connector snap-gauge, and the connector snap-gauge is formed with the pillow connection of connector U-shaped card
Annular anchor ear.
Further, the connector snap-gauge is bolted to connection with connector U-shaped card pillow.
Further, it is embedded with boom hoisting on the cable duct bank.
Further, through chamfered at the port of the overlap joint faulting of slab ends.
Further, after adjacent overlap joint faulting of slab ends docking, sealing strip is placed in the chamfering piece that port is formed.
Further, the port of cable pipeline is set as circular arc chamfering or expanding horn mouth.
Further, the length of the overlap joint faulting of slab ends protrusion end face is 200mm~400mm.
Further, the cable pipeline is in matrix arrangement, is by the arrangement of row × row：1 × N, 2 × N or 3 × N,
In, N=2,3 and 4.
A kind of construction method of cable duct bank of the present invention, is as follows：
1) foundation trench is excavated, laying bed course is simultaneously levelling；
2) it is laid with connector U-shaped card pillow, it will be in the bottom girder embedment bed course of connector U-shaped card pillow；
3) the overlap joint faulting of slab ends of comb is put into connector U-shaped card pillow by crane cable comb, and ensures to overlap the edge of faulting of slab ends
It is aligned with the edge of card pillow；As needed, the laterally assembled of cable duct bank is carried out, and ensures that overlap joint faulting of slab ends is right in a lateral direction
Together；
4) laterally after the completion of assembly, the chamfering position at the port of overlap joint faulting of slab ends, adhesive seal item, and a reserved fixed length
The sealing strip of degree；
5) longitudinal assembly is carried out to cable duct bank along the axial of cable duct bank, the overlap joint faulting of slab ends of comb is put into connector U-shaped
It is docked in card pillow and with the overlap joint faulting of slab ends of the laterally cable duct bank of assembly, the edge for overlapping faulting of slab ends is aligned with the edge that card is rested the head on；It is vertical
To after the completion of assembly, reserved sealing strip is adjacent to and is docked in the chamfering piece to be formed in two combs；
6) it in the top erection joint snap-gauge of connector U-shaped card pillow and is compacted, using bolt by connector snap-gauge and connector U-shaped card
Pillow is fastened as a whole；
7) it repeats step 4), 5) with 6), constructs and finish up to a section；Last foundation trench backfill, construction terminate.
Beneficial effects of the present invention are：
(1) cable duct bank of the invention can realize lateral single layer multiple row, multilayer with modularized production, modularization assemble
The assembled arrangement of multiple row comb meets the arrangement form of existing various comb designs.
(2) connector U-shaped card pillow effectively embraces the cable duct bank being laterally arranged in juxtaposition forms entirety together, limits electricity
The lateral movement of cable comb ensures the globality of comb and the accuracy of longitudinal cable pipeline docking；Pass through with connector snap-gauge
Bolt forms an annular anchor ear, and card has the cable duct bank of joint both direction in length and breadth in arms, is further ensured that the connection of connector
Intensity.
(3) connector U-shaped card pillow bottom girder can be thickeied according to engineering demand, had both the effect of sleeper, made cable duct bank connector
Place does not generate longitudinal and transverse direction displacement because of the effect of stress, ensures the globality of cable duct bank, can in the area that basis is poor
The basement process of U-shaped card napex is only done, comb is in integrally both ends freely supported structure, saves whole ground processing cost.
(4) sealing joint strip that one trap of setting is closed in the chamfering piece space that overlap joint faulting of slab ends joint is formed, passes through snap-gauge
After compacting connection, it is effectively guaranteed the water resistance of joint, prevents slime water from penetrating into cable pipeline.
(5) circular arc chamfering of cable pipeline port or one end are set as expanding horn mouth, effectively eliminate longitudinal 2-section pipe
Nozzle faulting of slab ends caused by road contraposition is inaccurate ensures smoothly penetrating for cable, eliminates nozzle faulting of slab ends and is scratched to cable.
(6) cable duct bank form of construction work of the invention is all connected using dry type, and scene is without a large amount of wet constructions, and environmental protection is without dirt
Dye, no formwork assembling and disassembling operation, be not necessarily to concrete curing, install can grave mound restore place original appearance, quickness and high efficiency.
