The leakage of musical fountains is closely related to the use of different natures. The larger the cement particles, the smaller the surface area, the lower the activity, the smaller the shrinkage rate and the higher the heat of cremation. The shrinkage rate of ordinary Portland cement is lower than that of slag cement, fly ash cement, bauxite cement and quick-quenching cement, and the heat of cremation is lower than that. The sandstone shrinkage rate increases and the mud content increases. The larger the aggregate size, the smaller the sand rate and the smaller the shrinkage rate. The greater the water-cement ratio, the greater the shrinkage rate, the greater the reinforcement ratio, the smaller the shrinkage rate. In most cases, ordinary Portland cement is widely used, but the influence of natural resources and environmental factors is replaced by other materials in different places, and leakage is caused to some extent.
1. Formwork and reinforcement binding are not carried out in accordance with the requirements of technical specifications.
2. In order to facilitate construction, concrete should be added to the concrete during the concrete pouring process to improve the workability and fluidity of the concrete. The slump becomes stronger, the viscosity decreases, the strength and impermeability decrease, and the concrete solidifies and solidifies seriously.
3. In the concrete pouring project, the vibrator is not used to vibrate the concrete, so that the internal compactness of the concrete is insufficient, resulting in the shrinkage and shrinkage of a large number of honeycombs or holes in the rear wall of the concrete.
4. There are no eight steel bars on the side wall and bottom plate of the waterscape, resulting in stress concentration and instability.
5. The contact position between the waterscape equipment pipeline and the concrete is not properly vibrated and compacted, and it is easy to produce small cracks at the contact position.
