[0009] The present invention is to provide a waterproofing sheet by spraying a preferably hardened primary spraying cement concrete onto the excavated tunnel surface, and then arranging a waterproofing sheet having an adhesive property with the secondary lining cement concrete. This is a method of integrating tunnels. This waterproof sheet follows the cracking of the cement concrete due to the influence of the drying shrinkage of the secondary lining cement concrete and the ground after completion, and the like. By integrating the cement concrete and the waterproof sheet, even if the waterproof sheet is damaged, only the damaged part comes into contact with water.
Water leakage does not occur unless cracks occur in the secondary lining concrete at the sheet breakage portion, so that the probability of water leakage is greatly reduced and good waterproof performance is obtained. In addition, water penetrates into the gap between the waterproof sheet and the secondary lining cement concrete as in the conventional waterproof sheet, impairs the waterproof performance of the entire tunnel, and causes water leakage due to cracking of the secondary lining cement concrete. There is no. Furthermore, even if cracks occur in the tunnel itself, the waterproof sheet integrated with the secondary lining cement concrete has good crack followability and does not break, preventing water leakage. Is improved.

After placing the secondary lining concrete, 28
One day later, the specimen was cut out by boring, and the adhesion to concrete was checked. The secondary lining concrete and waterproof sheet were well bonded and integrated. Peel strength between secondary lining concrete and waterproof sheet is 0.9N / mm
That was all. The cuts were also well integrated with the secondary lining concrete, and the cuts in the concrete had a linear shape of 2 mm or less. In addition, although a hydrostatic pressure of 60 m was applied to the gap between the primary sprayed concrete and the multilayer waterproof sheet, water did not enter the gap between the multilayer waterproof sheet and the secondary lining concrete, indicating good waterproofness. In addition, since the used multilayer waterproof sheet has adhesiveness, the multilayer waterproof sheets can be adhered to each other simply by overlapping the ends of the multilayer waterproof sheet. Therefore, the workability was very good, and the adhesive strength at the overlapped portion was 1.7 N / mm, which was an excellent value. In addition, stress was applied to the secondary lining concrete assuming cracks in the tunnel to form cracks, but no abnormality was found in the multilayer waterproof sheet.

Even if a part of the waterproof sheet is broken, water does not enter the gap between the waterproof sheet and the secondary lining concrete, and good waterproof performance can be secured. Moreover, the waterproof sheet of the present invention has good crack followability, and even if cracks occur in the secondary lining cement concrete, the waterproof sheet is not damaged, and good waterproof performance can be secured. Even if the crack width is large and the tarpaulin is damaged, the other part of the tarpaulin is integrated with the secondary lining cement concrete, and water enters the gap between the tarpaulin and the secondary lining concrete. Because it does not, its industrial benefits are huge.
