坑道用水下堵漏剂的研制

Development of under-water plugging agents for tunnel

坑道水下堵漏剂的研制包括F - 1、F - 2和F - 3型。其中F - 1是一种有机堵漏剂 ,它可以在水中固化 ;F - 2是一种无机防水堵漏剂 ,施工方便 ;F - 3是速凝型 ,它可在瞬间固化 。

The under water plugging agent for tunnel comprises three types: F-1,F-2and F-3.F-1 is an organic plugging agent and can harden under the water.F-2 is a inorganic plugging agent and can directly mix with the cement, it is easy to work.F-3 can instantaneously harden and is suitable to plug the gushing leak.
