Abstract

[0002] During the construction of the basement raft foundation, steel pipe supports and steel sections are usually used for thicker rafts. Compared with steel sections, steel pipe supports have the advantages of less welding, faster construction speed, lighter weight, and better economy. Therefore, the use of steel pipe supports for raft reinforcement is increasing. Usually, before pouring the raft foundation concrete, the steel pipe columns are manually grouted to reduce the risk of leakage at the steel pipe columns. This grouting method cannot seal the bottom of the steel pipe tightly, and gaps are easily generated between the steel pipe and cement slurry during long-term contact. It is impossible to fundamentally solve the leakage problem at the steel pipe support column, thus affecting the quality of the basement raft project. In addition, the grouting method for steel pipe columns also has problems such as high difficulty in operation, low construction efficiency, and high construction cost. Utility Model Content
