1708 Shexian underground pipe waterproof sealing example

Release time:

2020-02-09

The main problems encountered: 1. Pipes are mostly extruded deformation, its shape change more than 5%; 2. Many pipeline pipe mouth split, cable pipe wall appears serious damage; 3. Pipeline wells in the accumulation of water is serious, through the connected cable pipe makes the various underground cable pipe are water; 4. Many reserved pipe for the later laying of cable reserved, can not be blocked fixed, need to be flexible; 5. Cable not specification through the pipe, resulting in many Cable close to the pipe wall; 6. Underground cable well environment, construction difficulties; 7. Empty pipe, single, fine cable uneven, blocking material is difficult to choose; 8. Wells in the clutter, dirty, messy, miscellaneous; 9. Corner pipe, located in the 90-degree angle is difficult to blocking. 1. inflatable cable pipe sealing device, a new type of cable pipe sealing material, the use of inflatable expansion type extrusion principle, you can fill the various gaps between the cable and the cable wall to achieve a completely sealed degree; 2. inflatable principle can be filled without the need to fill in accordance with the specifications of the pipeline, elliptical, square can be completed to achieve the purpose of sealing the sealing needs to be achieved; 3. because there is no need to fix the blocking of the pipeline mouth, you can arbitrarily Select the pipeline can reach the blocking position, because the blocking pipeline mouth has been broken cable pipeline is one of the preferred blocking material; 4. This device uses polymer soft metal materials, can effectively resist the water immersion, acid and alkali, etc., effectively improve the resistance to ensure that the blocking pipeline inside the clean; 5. Convenient operation, low construction environment requirements, for eccentric cable, the size of the cable has a good sealing The new repeated trial inflatable cable duct sealing device can be used repeatedly on the basis of achieving the sealing conditions, effectively saving the late maintenance, management costs.

The main problems encountered:

1. Pipelines were mostly extruded and deformed, with a deformation of more than 5 per cent;

2. many pipeline orifices were split and the cable duct walls were severely damaged;

3. serious accumulation of water in the pipe wells, and water accumulates in underground cable ducts at various places through the connected cable ducts;

4. many reserved pipes are reserved for the later laying of cables, which cannot be blocked and fixed, and need to be flexible;

5. cables were not threaded through the ducts in accordance with specifications, resulting in many cables being tightly attached to the walls of the ducts;

6. the harsh environment of underground cable shafts, making construction difficult;

7. empty pipe, single, thin cable uneven, blocking material is difficult to choose;

8. a lot of clutter in the well, dirty, messy, miscellaneous;

9. there are corner pipes, located at 90-degree angles difficult to blocking.

1. Inflatable cable duct sealing device, a new type of cable duct sealing material, the use of inflatable expansion type extrusion principle, can fill the various gaps between the cable and the cable wall, to achieve a completely sealed degree;

2. Inflatable principle can be filled without the need to fill according to the specifications of the pipeline, oval, square can be completed blocking needs to achieve the purpose of blocking;

3. Because there is no need to fix the plugging pipe opening, you can choose any accessible plugging position in the pipeline, and because plugging cable ducts where the pipe opening has been broken is one of the preferred plugging materials;

4. This device is made of polymer soft metal material, which can effectively resist immersion in water, acid and alkali, etc. It effectively improves the resistance and ensures the cleanliness inside the blocked pipe;

5. Convenient operation, low construction environment requirements, for eccentric cables, large and small cables have good sealing, effectively overcoming most of the adverse factors of the blocking environment;

6. The new repeated test inflatable cable duct sealing device can be used repeatedly on the basis of achieving the sealing conditions, effectively saving the later maintenance, management costs.
