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.

To address the problem of sluice concrete easily cracking during construction, this study introduces the crack mechanism of concrete structures. Temperature differences and constraints are the main causes of cracks. Anti-cracking measures should focus on optimizing concrete mixing ratio and improving construction technology. Using simulation calculation to model the actual construction process and temperature control measures, this study analyzes the causes of crack and selects timely and reasonable temperature control measures, which are necessary links in engineering construction. A three-dimensional finite element analysis was conducted for a huge concrete sluice structure. The causes of cracks are discussed, and timely and feasible anti-cracking measures are proposed to provide technical support for project construction.
