Background technology
Along with China's rapid economic development, various urban infrastructure gradual perfections, construction and the maintenance to underground utilities
Propose higher standard and requirement.Underground communication, power pipeline typically all use the materials such as plastics, fiberglass, cement
Material, be embedded in the ground lower groove and comb dug in advance, and artificial well be set in a certain distance, as wiring, examination,
The operating point of the management line security such as maintenance, maintenance.Operating point is typically all the main body making artificial well of concrete, due to each well it
Between connect pipeline all communicate, if pipeline do not do waterproof sealing process or deal with improperly, be easily caused rainwater, sewage,
Mud etc. flow into work well and cable channel, cannot rush to repair in time when certain section of cable breaks down, and cause and cannot estimate
Loss.
Cable tube road junction flexible blockage technology WQBZ cable inflatable duct enclosure systems, it is adaptable to buried cable pipe
Closure imported and exported by road engineering and basement cable channel, and waterproof, antiseepage, protection against rodents settle at one go.Aluminum foil composite is made
Inflation pipe close, it is simply that utilize the principle of inflation that pore is realized closure.Marine glue is posted in inflation pipe close both sides, and marine glue exists
When inflation reaches 2.6-3.0bar, pipeline, inflation space between pipe close, cable three can be filled up completely with, to reach complete
The effect sealed.Inflation pipe close air-filled pore inside install silica gel material, when gas of substituting the bad for the good pulls out gas tube, silica gel material from
Air-filled pore can be blocked by the performance that I fills at once, it is ensured that gas does not leaks.
Acid and alkali alkaline environment affects, and is not affected by pipeline flowing water, standby blank pipe, unit cable pore, multi-cable pipe
Hole can be installed.

Goodization good looking appearance；
G pulls out inflation pipe close；When the blowing pressure list index points to 2.6-2.8bar position, gas-filled switching tube can be closed, and
Confirming gauge hand position no change, the time maintains between 30 seconds to 120 seconds, the most again by gas tube from gas tube the most beyond the Great Wall
Pull away；
Wherein, described dummycable mounting process is:
After inflation pipe close is moved on to block-up position, after step e, take a dummycable and put in the middle of inflation pipe close, put
Entering degree of depth 10cm, align bottom inflation pipe close, exposed parts, in the scope of 3-5cm, carries out the inflation of step f the most again；
Wherein, described rubber bushing mounting process is:
Before inflation pipe close is installed, after the release paper of the first rubber bushing outer layer is torn and smears lubricant, move
Enter pipe plugging position, along inner-walls of duct outwards firmly by tight；The mounting means of the second rubber bushing is identical, with the first rubber lining
Set installation site alignment.
Further, described cable pressurization formula sealing technology directly uses gas tube to fill in row closure, and the caliber being suitable for exists
50mm-150mm scope.
Further, described dummycable mounting process is the plugging technology combined with cable pressurization formula sealing technology,
The caliber being suitable for is in 150mm-180mm scope.
Further, described rubber bushing mounting process is the plugging technology combined with dummycable mounting process, suitable
Caliber in 150mm-300mm scope.
The method have the advantages that
The plugging technology that the present invention is directed to different cable pipe diameter size devises the mode of three kinds of different-effects, this technique
Purpose on the one hand, can quickly be prevented by the cable inflatable duct enclosure systems of employing by electricity channel cable run pipeline
Water-stop, reduces cable channel maintenance cost, is the most also the effective means improving cable channel repairing working performance；The opposing party
Face, this process provides one more to clean for artificial underground work or underground pipeline construction, dry working environment, and
In a very long time, obtain the trouble first drawn water and time before exempting construction, shorten each engineering time, prevent mouse from entering pipe
Line causes unnecessary loss；It is effectively improved the success rate of inflated type duct enclosure systems closure, reduces unnecessary to material
Waste.
Certainly, the arbitrary product implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
