Description

Technical Field

[0001] The utility model relates to the technical field of coral soil subbase construction devices, and particularly relates to a coral soil subbase construction device. Background Technique

[0002] Due to its porous structure and high specific surface area, coral soil can be well combined with binding materials such as cement. Active components such as silicate and aluminate in cement react chemically with the surface of coral soil particles under the action of water to form hydration products, enhancing the bonding force between particles; coral soil contains particles of different particle sizes. By screening and re-blending, the particle gradation can be optimized, and the density and uniformity of the mixture can be improved; the coarse particles provide skeleton support, and the fine particles fill the voids, jointly improving the bearing capacity and stability of the subbase.

[0003] The existing coral soil subbase construction device mixes cement and coral soil twice on the ground to improve the strength and volume stability of the coral soil to the cement mortar. Although the above method can realize the mixing effect of the device on coral soil and cement, when the device mixes cement and coral soil, the hard oversize materials in the coral soil subbase will affect the balance of the aggregate, causing a certain impact on the compaction effect and the uniformity of the foundation. The hard oversize materials in the mixing process need to be removed separately, resulting in a long preparation time before the device is used. At the same time, when mixing cement and coral soil, the two have a certain viscosity and are easy to stick to the mixing knives. Long-term accumulation is easy to cause difficulties in the rotation of the mixing knives. Content of the Utility Model
