Customized tremie pipe
If the tremie is buried too deep, the fluidity of concrete in the tremie will become poor, which is easy to cause pipe plugging. If the buried depth is too shallow, the newly poured concrete will easily break through the original concrete, so that it will not flow under the original concrete protective layer, but above it. In this way, it is easy to cause sandwich pile breaking, so the buried depth of the tremie is generally 2-6m.
