Leakage prevention method using the in water leakage prevention for the seal material and leakage prevention for seal material in concrete structures

摘要

Disclosed is a low-cost leakage prevention sealing material for the construction work can be easily realized can be made a construction time of and leakage prevention sealing material without falling off from the joint portion when applying a leakage prevention sealing material is to provide a technique for leakage prevention method used. A 18 is a joint portion formed on the seam of the concrete structure 17, the two wall portions 17a, 17a are disposed to face. Internal inserted instrumentation in a substantially longitudinal leakage prevention for the seal material 19 stands clogs shape tubular body portion 19A and the symbolic geta shape tubular body portion 19A having a top wall portion 19a along with adapt to the external shape of the joints 18 to become a sponge portion 19B which is formed a rectangular hole 19f, and an axially elongated and is formed a substantially rectangular cross section. Structure of water prevention for seal material 19 I have configured easier fitted into the joint portion 18. [Selection Figure] Figure 1
