Description
Technical field
The utility model relates to a kind of heavy-caliber fiber reinforced plastic pipe flange leakage treatment devices, belong to pipeline maintenance technology neck
Domain.
Background technique
Heavy-caliber fiber reinforced plastic pipe passes through longtime running, in flange connections since flange, flange gasket or connection bolt are old
Change causes interface infiltration situation.Large diameter pipeline maintenance because small leakage is cut off the water, will affect the normal operation of pipeline, can shadow
The scheduling of entire company is rung, therefore the maintenance that generally will not all cut off the water.In the case where not cutting off the water maintenance, traditional maintenance method be from
Pipeline external directly with glass cloth add glue carry out ring paste maintenance, this method due to ring paste when can not completely sealing and cause to have repaired
Afterwards, new paste material and old pipe layered are occurred as soon as by three, five months or in a year or so and is leaked again, and leak is to water delivery repeatedly
Pipeline causes security risk, also results in economic loss.

Excessive, the control of slip casting machine gage pressure is advisable in 200MP, and each injected hole successively after slip casting, complete by first time slip casting；
6, start second time slip casting after waiting 20-30 minutes, still successively slip casting from the bottom to top, second time grouting pressure
It is greater than first pass, will appear bubble in the two sides of clip one and clip two when slip casting, while flowing out with Heisui River, until slip casting
Liquid is squeezed out from two sides, and there is no bubbles and Heisui River to emerge at this time, and slip casting machine pressure is in 300MP or so, second time slip casting at this time
Terminate；
7, start third after waiting 20-30 minutes all over slip casting, third does not need successively slip casting all over slip casting, carefully looks into before slip casting
Seepage point is looked for, where is it seepage point is with regard to carrying out slip casting with two nearest slip casting nozzles, until injection slurry flows out；
8, it waits 30 minutes, whether there is or not seepage points for observation, if there is continuing slip casting by the method for third time, if do not repaired
Terminate.
The good effect of the utility model: structure is simple, and the service life after capable of substantially extending maintenance will not leak repeatedly
Water not will cause security risk, reduce the duplication of labour, improve working efficiency.
