Description
Technical field
The present invention relates to multi-functional trussings, more specifically to cable duct side wall template truss system, belong to
Engineering electric industry field.
Background technology
As China's economic level is showing improvement or progress day by day, nationwide integrated power grid is laid with erection quantities and is substantially increased, it is therefore desirable to synchronous
A large amount of cables are laid with, as the important component of transmission line of electricity, are chiefly used in the laying of substation or Urban Underground circuit.But
Because of cable own wt, high-voltage safety and economic angle etc. influence is laid with, the engineering hand that generally use cable duct is laid with
Section, cable duct are usually to be built by laying bricks or stones according to the design requirement excavation of safety in utilization, the load slotted-angle shelving in the welding of its madial wall,
Grounding construction is carried out at the same time as safety precautions, and in groove face upper cover upper cover plate, the underground for forming complete cabling is special
With channel, one realizes the purpose of hidden laying, and two save space to reduce aerial cable, the most key is that can also ensure
Cable safe to use and there is counter-measure when there is high pressure leakage accident.Truss is hingedly formed at both ends each other by rod piece
Structure, the advantages of truss is that rod piece can bear pulling force or pressure, gives full play to the self attributes effect of material, saves material
Material mitigates construction weight, and can realize functional exercise.
There is following Railway Projects for current cable duct engineering：
(1) existing cable duct section is the rectangular configuration of upper opening, and opposite notch, indentation, there are set at the top of inner wall
Cover board is installed, and processing is sealed to it, but after use after a period of time, sealing can also fail, if in cable duct
Nearby there is ponding, water will be flowed into cable duct, and then forms wet environment, get off to cause cable by cargo sweat etc. for a long time.
(2) when there is rainy season, above-mentioned situation can be further aggravated, and a large amount of rainwater is poured in cable duct, can will be electric
Cable floods, and the insulating properties of equipment is greatly reduced, and causes node device substation etc. that flashover fault occurs, influences power supply safety
It is run with equipment.
(3) when there is the above situation, not only with the situation of insulating properties reduction, also very maximum probability causes cable to damage
The electric leakage of bad high pressure happens, and is also impregnated simultaneously by ponding to the circuit of ground protection originally at this time, and not only protection is made
With failure, more wide high pressure can also be caused to leak electricity and reveal range, cause more serious destruction.
It (4), can be because wet environment grows or mosquito mouse ant is attracted to enter cable in the presence of above-mentioned ponding situation is of short duration
Cable is extremely easily gnawed or destroyed to ditch, such biology, if but carry out dispensing spill medicine insecticidal operation, after rainwash
Also it can fail, constantly can only largely repeat operation, increase workload.
(5) because of the operations such as cover plate for sealing, belong to a non-current space of opposing seal, an intensive electricity in cable duct
Cable transmission can cause largely to generate heat, and when two same day directly penetrated, heat can constantly penetrate savings can not dissipate in the space, and
Ventilating is simultaneously unrealistic, if without effective heat dissipation, gently it will cause cable jacket rubber or other ditch inner parts because
Overheat and coking or aging are serious, it is heavy then or even fire incident can occur.
So in view of the above-mentioned problems, designing and developing a kind of can dredge and take precautions against ponding and possess maltilevel security guarantee
Cable duct side wall template truss system becomes urgent need instantly.
