Vacuum preloading fails.Therefore, the patch work of diaphragm seal is extremely important, once finding that diaphragm seal has rupture, should be repaiied in time
It is multiple, to ensure vacuum degree and construction quality.
There are mainly four types of the method for repairing and mending of existing diaphragm seal：
First, not covering water on film, conventional vacuum can be taken to mend membrane technology, be as follows：1st, it finds at hole
(under normal conditions, the hole of diaphragm seal is less than 10cm), about 30cm is cut off with blade, while optionally cut off geotextiles under film,
Such as vacuum suction forms pit-hole, it is preferably with clay that pit-hole is plain, and repair geotextiles covering；2nd, by double-layer seal at hole
Film must not have soil pollution and water stain residual respectively with paper handkerchief by its wiped clean；3rd, two pieces are cut respectively with scissors at least to cover
Hole periphery 20cm circles mend film, and hole film side and benefit film are coated vacuum diaphragm glue special respectively；4th, film difference is mended by two pieces
It mends inside and outside double fenestra holes, overlapping together, air-dries.
Water is covered second is that having on film, need to carry out mending film under water, sluicing method can be taken.This method is：Water whole will be covered in cofferdam
It takes away, leaks out film surface, then operated by above-mentioned conventional membrane technology of mending, after the completion of repairing, the ascites on diaphragm seal, insufficient again
Part is：A, claim for eot is caused；B, construction cost is high.
