Construction technique of inspection weli for water drainage pipe jacking project with sunk tube method

摘要

Inspection well is needed for water drainage pipe jacking project in municipal engineering construction, and the deep ones are usually built by sunk tube method. According to a real project, this paper dissertates the construction technique of deep buried inspection well with sunk tube method under the condition of abundant water existence form the aspect of design theory and construction technique and emphasizes the problems and countermeasures during tube sinkage. The practice shows that inspection well with sunk tube method could resolve the difficulty of construction in Water-soaked Stratum.
