[0002] During the hardening process, building materials such as cement mortar, cement concrete, and polymer mortar will always be accompanied by volume expansion and contraction. Currently, non-contact bellows are often used to test the expansion and contraction of materials. Although high-precision and high-sensitivity sensors can record the deformation of the material in real time, the problem of sample molding inside the bellows affects the accuracy of the test results.
[0003] When artificial vibration molding is used, since it is difficult to control the vibration amplitude and frequency of the pipe during the vibration process, problems such as splashing and overflow of the slurry in the corrugated pipe often occur. If the vibration is insufficient, the slurry will not be dense, and if the vibration is excessive, it will segregate. In the vertical molding process of plastic corrugated pipes that are too long, the middle section is prone to horizontal displacement, which will cause the corrugated pipe to undergo inelastic deformation, seriously affecting the test results.
