[0002] Self-compacting cement soil is made by mixing inorganic cementitious materials with soil and water in proportion, also known as cement soil. It is generally replaced by self-compacting cement soil when used in the construction of pile foundation holes for bridge projects. Cement soil needs to solidify but does not require very high strength, so it requires a specific test mold box to form. The cement soil slurry is formed after vibration compaction. At present, it is mainly demolded by manual handling and then inverted. The demolding is relatively difficult, which increases the demolding time and affects the turnover efficiency of the cement soil test mold.

[0003] Therefore, it is necessary to develop a self-compacting cement soil test mold device which has a simple structure, quick demoulding, and is easy to move after the test mold is detached. Summary of the invention
