Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an auxiliary device and an installation method for a large-diameter concrete pipe. Background Art

[0002] Concrete drainage pipes are widely used in municipal rainwater and sewage drainage pipe projects. Concrete drainage pipes are usually composed of concrete pipes and rubber rings. They provide good drainage protection through concrete pipe connections and sealing rubber rings. They are characterized by good durability, strong bearing capacity and good adaptability, and can meet the use requirements in various environments and geological conditions. Therefore, concrete drainage pipes have become a commonly used type of pipe in municipal engineering; however, when installing large-diameter concrete pipes, the pipe diameter is too large and it is difficult to push it into place manually. Therefore, most of them use excavator buckets for single-point pushing. During the pushing process, the pipes are unevenly stressed, which often leads to uneven gaps between adjacent pipes after installation and the seam width does not meet the standard.
